1. Summary This report on the Island Copper Property was prepared following the completion of field work for 2003. It describes the geology and mineral potential of the property, and presents the results of the exploration that has been carried out to date. The Island Copper property is located approximately 19 kilometres northeast of Sault Ste. Marie, Ontario. The property is situated northwest of the junction between Highways 556 and 552, and straddles Highway 552. The Island Copper property is comprised of four Falconbridge claims, three YMCA patents and the Nystedt leasehold patents. Under a January 2002 option and Joint venture agreement, Amerigo Resources Ltd. (Amerigo) has the right to earn a 55% interest in the property from Falconbridge Limited (Falconbridge) by spending $250,000 on exploration and issuing 200,000 shares over three years. Nikos Explorations Ltd. (Nikos) has agreed to acquire Amerigo’s interest in this property. The target of exploration on the property is iron oxide copper-gold mineralization of the Olympic Dam style. Previous work outlined copper mineralization hosted by altered, hematite-rich albite granite breccias at and near the contact with Archean-aged gneiss. The mineralized breccia occurs near the intersection of two major structures, and displays alkali metasomatism (Na +/- K enrichments), and chlorite, amphibole and Fe-oxide alteration. The copper mineralization consists dominantly of chalcopyrite with minor bornite associated with pyrite and specular hematite. Historical work on the property includes at least 37 diamond drill holes drilled mainly in the southeastern portion of the property to a maximum vertical depth of ~ 137 meters. Copper values are reported for most of the drill holes, but cannot be independently verified due to improper storage of the core. Drilling for which reports are available was undertaken in the 1960s and early seventies. The best intersection of 3.40% Cu and 0.9g/t Au over 11.59 metres that contained 6.22% Cu and 1.7 g/t Au over 3.5 metres, occurs in Hole 65-1 drilled in 1965 by Kennco Explorations. This intersection was not specifically tested during Amerigo’s 2002 drill program. Recent work undertaken by Falconbridge Ltd. includes detailed geology, surface sampling, and magnetic, gravity and induced polarization geophysical surveys. The results of the geophysical surveys indicate broadly coincident east-west trending gravity and chargeability highs.

Since signing the agreement with Falconbridge, Amerigo Resources Ltd has carried out rock sampling, diamond drilling, an airborne magnetic survey and a mobile metal ion (MMI) soil survey. Further surface work is recommended to advance the property to a second stage drill program. 2. Introduction and Terms of Reference This report describes the geology and mineral potential of the Island Copper property, and the geological work that has been carried out to date. It was written in order to allow an evaluation of the technical merit of the property as it pertains to the acquisition of the property by Nikos Explorations Ltd. Dr. Moss is currently Vice President of Exploration for Amerigo. He has been involved in exploration on the property since January 2002 and directly supervised all of Amerigo’s work. The present evaluation is based largely on this experience, prior technical reports, and current and historical data. Dr. Moss developed Amerigo’s model for IOCG exploration in the Sault Ste. Marie area and has been active in the investigation of Proterozoic Fe-oxide Copper-Gold deposits for the past three years. Mr. Tortosa is a professional engineer and an experienced geologist familiar with the Island Copper property. While consulting for Amerigo, he reviewed all diamond drilling on the property for the purpose of assessing the applicability of three dimensional modeling of the data. 3. Disclaimer All statements regarding historical diamond drilling and associated assays cannot be independently verified, since the drill core has not been maintained in a useable condition. Also, historical surface assays have not been independently verified. While drill logs with assay data are available for review, there are no assay certificates to accompany the drill logs, and so all reference to historical drill intersections is taken from the drill logs.

4. Property Description and Location The Island Copper property is located approximately 19 kilometres northeast of Sault Ste. Marie, Ontario, (Figure 1). The property is situated northwest of the junction between Highway's 556 and 552, and straddles Highway 552.

The Island Copper property is

5

comprised of four Falconbridge claims, three YMCA patents and the Nystedt leasehold patents (Figure 2, Table 1). All claims are in good standing at the time of writing. The Falconbridge claims bound the patents held by the YMCA of Sault Ste. Marie on the north, west and southwest. The YMCA patents contain the main copper showings. Following the final $30,000 option payment to the YMCA on December 31, 2003 by Amerigo, Falconbridge has a 100% interest in the YMCA patents. Falconbridge also had an option on the Nystedt patents, which consist of two surface and mining leasehold patents owned by the Nystedt family of Sault Ste. Marie, Ontario. The Nystedt patents were optioned to Falconbridge Limited in August 2000. These claims are immediately south of the YMCA patents. Following the final option payment on October 1, 2003, Falconbridge became the 100% owner of the Nystedt Patents. Nikos has agreed to acquire three copper-gold properties located in the Sault Ste. Marie area, including the Island Copper property, from Amerigo Resources Ltd. effective December 31, 2003. Nikos will issue Amerigo 5,000,000 common shares upon final exchange acceptance, and will issue Amerigo 5,000,000 additional common shares at the option of Nikos on or before June 30, 2005 if Nikos retains an interest in any of the properties. The acquisition of these properties forms part of the application for the reactivation of Nikos from NEX to the TSX Venture Exchange. Subsequent to the agreement with Amerigo, Nikos renegotiated the option joint venture agreement with Falconbridge Limited. In order to earn the 55% interest in the property, Nikos has agreed to: 1) Issue 150,000 units of Nikos on TSX Venture Exchange approval of the transaction, with each unit comprising one Nikos share and one share purchase warrant, with each warrant entitling the holder to purchase one additional Nikos share for a price of $0.30 for a period of two years from the date of issuance; 2) At the election of Nikos, on or before January 21, 2005, either issue a further 150,000 Nikos shares or make a cash payment of $30,000; and 3) Spend no less than $100,000 in exploration on the property prior to January 21, 2005 or, if the full expenditure is not made, make a cash payment to Falconbridge for the remaining portion.

6

Once Nikos has earned an undivided 55% interest in the property, a 55%: 45% Joint Venture will be formed with terms governing said J/V usual to the mining industry. Alternatively Falconbridge may exercise a one-time option to increase its interest in the property to 65% (“bump up”) by electing, within 90 days of the Issuer having earned its 55% interest, to complete a bankable feasibility study on the property. If, based upon the outcome of the bankable feasibility study, a production decision is made, Falconbridge shall have 90 days to exercise a one-time option to increase its interest further to 75% by arranging for mine financing. Falconbridge will become Operator during said “bump up” periods. Should Falconbridge not exercise its right to increase its interest above 45%, the 55:45 J/V relationship between the Issuer and Falconbridge will continue to operate with the Issuer as Operator under the formal JV agreement. The joint venture partners will contribute, on a prorata basis, to exploration expenditures agreed upon by both companies. Failure by either Party to contribute its share to agreed-upon exploration expenditures on the property will result in dilution of its interest. Should either Party’s dilution reach 10% or less, that Party’s interest in the property will automatically revert to a 2% NSR. In the event that either Party’s interest reverts to a 2% NSR, the other Party shall have the option to purchase 1% of the NSR for CDN$1,000,000.00. The YMCA of Sault Ste. Marie and the Nystedt Family each have net smelter return royalties of 1.5% on future production from the property. Falconbridge has the right to buy back half (0.75%) of the royalty for $400,000 per property

5. Accessibility, infrastructure, local resources, climate and physiography The Island Copper property is accessed by way of the paved Trans Canada Highway north from Sault Ste. Marie to the town of Heyden (Figure 1) and thereafter by Highway 556 to Ranger Lake and Searchmont. The property lies ~ 5 kilometers east of Heyden at the junction of Highways 552 and 556, which is in the southeast corner of the property. The Algoma Central Railway (ACR) line passes along the southeast boundary of the property. A 5-car spur line is located off the gravel quarry on the eastern side of the property. DCI Investments of Sault Ste. Marie leases this quarry, located immediately east of Highway 552, across from the main Cu-showing of the Island Copper property, from the YMCA.

Infrastructure in the vicinity of the property is excellent. In addition to the abovementioned ACR railway line and paved highways, electrical power lines run along the highways, and air and port facilities are available in Sault Ste Marie. Sault Ste. Marie is a major commercial and industrial city of ~ 100,000 inhabitants located on the St. Marys River which connects Lake Superior and Lake Huron. Sault Ste. Marie serves a large portion of north-central Ontario, and is connected by bridge directly to Sault Ste. Marie, Michigan.

The climate and physiography of the property is typical of the Canadian Shield east of Lake Superior. The climate is northern temperate with warm summers and cold winters with snow from approximately November through to Early April. Moderately steep hilly terrain occupies the southern and central portions of the property, while the northern area drops steeply at first, then gently towards the Goulais River valley. The region is covered by a mixture of outcrop and overburden, consisting of glacial sand and gravel of varying thickness, covered by humus. Outcrop exposure averages approximately 10% and occurs predominantly as rocky ridges, on hilltops and as cliff faces. A thin veneer of glacial overburden and humus occurs along the flanks of rocky ridges and covers small valleys between the ridges in the southern areas of the property. The thickness increases northwards towards the Goulais River valley where outcrop exposure is minimal to non-existent. Thick stands of maple alternating with cedar and spruce are the main tree species in the area. Drainage along the northern portion of the property is towards the Goulais River and forms deep ravines with fast-flowing creeks. However, drainage is relatively poor in the central highland area of the property, and forms occasional swamps and beaver ponds between the hills with surface water available for diamond drilling. 6. History and Previous Work on the Island Copper Property The history of exploration on the Island Copper Property has been summarized by Camier and McLellan, 2000, Mumin and Camier, 2002, and Camier and Moss, 2003. The following summary is taken from Camier and Moss, 2003. Copper mineralization was discovered in the area over 90 years ago. However, very little information about early exploration is available. An historical exploratory adit exists on the property indicating the extent of previous work. Exploration in the 1950's culminated with some diamond drilling, however detailed assessment research by both Highland-Crow Resources Ltd. in the eighties, and Falconbridge Limited in 2000 did not find any records of this early drilling. The Geological Survey of Canada (1964) and the Ontario Geological Survey (1965) carried out regional reconnaissance mapping over the area. This was coincidental with prospecting in 1965 by Kennco Explorations (Canada) Ltd. near the old adit, and led to the discovery of the hilltop showing. This discovery inspired further work including line cutting,

10

geochemical surveys, geological mapping, geophysical surveys (ground EM, induced polarization), and the blasting of numerous trenches. The work concluded with 2,700 feet of diamond drilling in 14 holes (Table 2). The best intersection graded 3.40% Cu and 0.9 g/t Au over 11.59 metres (Table 3). Other than the drill logs, no record of the core was found. Other work includes prospecting and diamond drilling in 1970 by Mr. H. Nystedt of Sault Ste Marie, who drilled 503 feet in two drill holes southwest of the hilltop showings. Copperville Mining Corp Ltd. optioned the property in 1970 and 1971, and drilled 10 diamond drill holes for a total of 3,559 feet. The best intersection was 3.01% Cu over 4.3 metres (Table 3). No gold assays were found. Other companies that have worked in the area include Delta Minerals, Tri-Bridge, and Colleen Copper. Approximately 10,000 feet of diamond drilling in at least 43 historic drill holes has been recorded on or adjacent to the property. Unfortunately, the core is not recoverable and lays scattered amongst the leaf litter covering the property. As a result of a regional reconnaissance program conducted during 1980 and 1981, Highland-Crow optioned the property from the YMCA of Sault Ste Marie and Mr. Nystedt in 1981. Highland-Crow’s exploration included geological field mapping and geochemical sampling; however, they did not continue with any additional work on the property. No further work was carried out until Falconbridge optioned the property in late 1999, and staked additional contiguous ground to the north and west of the YMCA and Nystedt properties. In the spring of 2000, Falconbridge flew airborne radiometrics over the entire property. This was followed in 2000 by line cutting, detailed geological mapping and geochemical sampling (Camier and McLellan, 2000). The Nystedt property was optioned by Falconbridge in the fall of 2000, with detailed geochemical sampling and geological mapping conducted in 2001 (Camier and Oosterman, 2001). An induced polarization survey was carried out by Abitibi Geophysics on behalf of Falconbridge during August 2001, and gravity surveys were carried out in 2001 and 2002 by Quantec Geoscience Inc. Results of these surveys indicated partly coincident residual gravity and chargeability anomalies (Figure 3 and 4).

7. Geological Setting The geology of the property has been described in detail by Camier and McLellan, 2000; Camier and Oosterman, 2001; Mumin and Camier, 2002, and Camier and Moss, 2003 and is summarized below. 4.1 Regional Geology The property occurs in moderately to strongly foliated Archean gneissic-granitoid rocks of the Gros Cap Batholith, immediately north of the Archean-Proterozoic boundary (Figure 5). The boundary is delineated by the Highway fault (Proterozoic boundary fault) that parallels Highway 556 and the ACR rail line. This fault separates Proterozoic aged clastic rocks of the Aweres Formation in the Upper and Lower Island Lake areas from Archean gneiss. To the north and northwest of the property, clastic rocks of the late Keweenawan-age Jacobsville Formation unconformably overlie the Archean rocks (Camier and McLellan, 2000). Gros Cap Gneiss comprises the majority of the outcrop on the property. The gneissic rocks are composed of granite and granodiorite that have been strongly to moderately foliated, and contain localized migmatitic units. At several locations, the gneiss appears intensely sheared, altered, and crosscut by east-west trending chlorite-altered amphibole schist. The gneiss has been further intruded by numerous gabbroic to fine-grained diabase dikes of at least three different ages. Larger dikes trend in a west-northwest direction and display a gabbroic texture, moderate to weak magnetism, and weak chloritization. Finer grained, moderately to strongly magnetic diabase dikes trend in a northwest direction. Several, southeast trending and north-south trending dikes of strongly magnetic biotite-lamprophyre comprise the

Figure 5. Regional Geology in the vicinity of the Island Copper Property.

17

youngest mafic intrusive units (Camier and McLellan, 2000). The area is structurally complex and exhibits zones of intense faulting. Bennett and Innes (1977) state that the Archean-Proterozoic boundary, or Highway Fault, is a thrust or reverse fault trending northeast along the southern boundary of the property (Innes, 1983). This fault has been interpreted to represent the northern margin of the Lake Huron Graben Structure. The north-northwest trending Island Lake Fault crosscuts the gneiss on the eastern side of the property and is visible in outcrop along Highway 552. The Island Lake fault appears to be truncated and offset by the Highway Fault. The brecciated gneiss is primarily concentrated along the Island Lake Fault, and represents cataclastic brecciation formed in a zone of structural weakness, at the intersection of the two faults (Camier and McLellan, 2000). 4.2. Property Geology Detailed geological mapping of the Island Copper property was completed by Falconbridge Limited in 2000 and 2001, and is discussed in detail by Camier and McLellan (2000) and Camier and Oosterman (2001). Further discussion of the property is presented in technical reports by Mumin and Camier (2002) and Camier and Moss (2003). The majority of the rock on the property consists of Gros Cap gneiss (Figure 6). The gneiss consists of light gray to pink granite and granodiorite, comprised of plagioclase, quartz, and biotite ± hornblende. It displays a strong to moderate fabric or gneissic layering. Localized zones of migmatite consisting of alternating wispy bands of Fe-rich minerals are set in white quartz and pink feldspar, and in one location the gneiss is strongly albitized (Camier and McLellan, 2000).

18

Figure 6. Geology of the Island Copper Property (after Camier and McLellan, 2000).

19

Gros Cap gneiss is extensively brecciated in the eastern portion of the property straddling the north-northwest trending Island Lake fault on both sides of Highway 552. The gneissic breccia is recognized by angular to subrounded and occasionally stretched fragments, with moderate to well-defined gneissic layering still well-preserved. Fragments are set in a black to greenish-black matrix of occasionally silicified, chlorite-altered amphibole schist. The fragments are easily identified by the preserved gneissic fabric and differential weathering between the gneissic fragments and matrix. Some of the fragments exhibit intense potassic and/or hematite alteration (Camier and McLellan, 2000). Silicification is apparent in the breccia fragments and often overprints the matrix. Quartz also forms anastomosing to fragmental white quartz veins and veinlets between the fragments. Larger quartz veins crosscut both the massive and brecciated gneiss, forming anastomosing veins and stockworks that parallel the Island Lake fault. Some of these quartz veins are discontinuous, and appear to have been fractured and dislocated (Camier and McLellan, 2000). Hematite and chalcopyrite mineralization are confined to outcrops of pink albite-rich granite that intrudes the brecciated gneiss. This albite-rich granite appears to be a separate rock unit composed of 80-85% pink to pinkish-white albite crystals intermixed with K-feldspar and minor quartz, set within a microcrystalline quartzo-feldspathic groundmass (Camier and McLellan, 2000). The unit has undergone crackle or shatter brecciation with hematite (specularite) and chalcopyrite mineralization forming the matrix and alternating with occasional chlorite-altered amphibole schist veins. This granite does not exhibit gneissic layering or fabric and is interpreted as a separate rock unit. The contact between the albiterich granite and brecciated gneiss is sharp, with a very narrow chill margin extending into the albite-rich granite suggesting the gneissic breccia was lithified prior to emplacement of the albite-rich granite. Further evidence for this is suggested by the lack of hematite and chalcopyrite mineralization extending beyond the albite-rich granite and brecciated gneiss contact. However, some specular hematite veining associated with late quartz-filled fractures extends into the brecciated gneiss (Camier and McLellan, 2000). The albite-rich granite comprises a large portion of the cliff face, along which the historical adit is located, and outcrops at several locations to the north along Highway 552. However,

20

the main showing with abundant hematite and chalcopyrite mineralization within the albiterich granite is located between L88+00N and L91+00N on L100+00E on top of the hill above the adit. Only one exposure of the albite-rich granite occurs on the east side of highway 552, located along L91+00N in historical trenches cut into a cliff face. The trenches provide excellent exposures of hematite and chalcopyrite mineralization within the matrix of the albite-rich granite (Camier and McLellan, 2000). Detailed observation of the outcrop face indicates the unit may have been faulted and juxtaposed against unbrecciated gneiss (Camier and McLellan, 2000). The majority of quartz veins observed on the eastern side of Highway 552, appear to parallel the Highway Fault and trend in a north-northeast direction.

8. Deposit Types 8.1 Introduction The target of exploration at Island Copper is an Fe-oxide copper-gold deposit (IOCG). Iron oxide copper-gold deposits are attractive exploration targets due to their common large size and multi-metal nature. Exploration for these deposit types, especially among junior explorers, has suffered from the lack of rigorously defined models, both empirical and genetic, and well documented case histories. Several recent publications (Vancouver Mining Exploration Group, 2000; Porter, 2000; 2002) have however provided a broad framework of models and case histories that may be used in targeting areas for IOCG potential, and for designing follow-up exploration programs. However, as pointed out by Pollard (2000), IOCG deposits are part of a broad spectrum of copper-gold deposits that include both porphyry and skarn-type deposits and rigid application of deposit specific characteristics to exploration should be avoided. 8.2 Characteristics of IOCG deposits While IOCG deposits range in age from the Archean to the Neogene, many of the deposits, including most Australian examples such as Olympic Dam and Ernest Henry, are Proterozoic in age. There are many inferred tectonic settings for the deposits, with an anorogenic or rift-related setting being most widely postulated (Barton and Johnson, 1996). However, it appears that regardless of the specific setting, an extensional environment is of fundamental importance (Gandhi and Bell, 1995). A strong structural control is noted in most

21

deposits, with mineralization emplaced along major regional faults or fracture systems, at intersections of faults or in axes of major fold systems (Oreskes & Hitzman, 1993). Typically IOCG deposits show spatial and temporal links with igneous rocks, including alkalic granitoids and volcanic rocks, calc-alkalic mafic, intermediate and felsic suites, continental flood basalts and rift-related basalts (Barton & Johnson, 1996). Many deposits are directly associated with the emplacement of high level felsic plutons (Ghandi & Bell, 1995; Wall, 2000), typically occurring in the roof zones of the pluton (Ethridge & Bartsch, 2000). Mineralization is commonly hosted by hydrothermal intrusive breccias or diatreme breccias (Reeve et al., 1990; Pollard, 2000). IOCG mineralization consists of Ti-poor iron oxide, with lesser phosphates, Cu- and Cu-Fe sulphides, and variable Au, U, Ag and Co (Barton & Johnson, 1996). To some degree it is the low Ti nature of the iron oxide that ties otherwise disparate mineral deposits of the IOCG class together. The most common iron oxides are hematite and magnetite. Magnetite is typically early and occurs in the deeper or more proximal parts of the hydrothermal system, whereas hematite is later, more distal and may overprint the earlier magnetite (Barton & Johnson, 1996; Oreskes & Hitzman, 1993). The magnetite may be accompanied by apatite (e.g. Kiruna) and Cu-Fe-Sulfides (e.g. Ernest Henry, Candelaria) and widespread sodic alteration. Gold and Cu-Fe sulphides are associated with hematite-stage mineralization at Olympic Dam (Reeves et al., 1990; Barton & Johnson, 1996). A broad range of elements may be associated with the mineralization. Apart from the Fe, Cu and in some cases Au and Ag, comprising the mineralization, deposits may be anomalous in Ba, P, F, Cl, Mn, B, K, REE, U and Na and have elevated Co, Ni, Te, As, Mo and Nb abundances, whereas Ti and Cr tend to be depleted (Foose & Grauch, 1995). Exploration for IOCG deposits relies heavily on gravity and magnetic surveys, with coincident gravity and magnetic anomalies being the preferred target (Gow et al.,1994). Detailed aeromagnetic surveys are recommended to map structure in the area of interest with likely dilational sites targeted for further follow up using alteration and geochemistry to site drillholes (Etheridge & Bartsch, 2000).

8.3 Application to the Amerigo Property The following features, considered to be key exploration criteria for IOCG deposits, are relevant to the Island Copper Property:

• • • • • •

Gold and silver occurs along with copper Hematite and minor magnetite is associated with the mineralization Major crustal-scale faults, including the Highway Fault that divides Archean rocks from Proterozoic rocks, are present on the property The presence of both an aeromagnetic anomaly and a gravity anomaly Significant sodium- (albite) and iron- (hematite) metasomatism The mineralization occurs near the boundary between Archean and Proterozoic rocks, along the margins of a major re-activated graben structure.

9. Mineralization Near surface mineralization on the Island Copper property consists of Fe-oxide (hematite ± magnetite), pyrite and chalcopyrite occurring between trace and 6 wt % chalcopyrite, with surface weathering to malachite and azurite. The hematite and sulphides occur as intergranular fillings, disseminations and anastomosing veins and veinlets of chalcopyrite and pyrite along with hematite ± magnetite (Camier and Mumin, 2000; Appendix 1). The mineralization plus chlorite and amphibole form the matrix of a crackle and/or shatter breccia in the albite-rich granite. Copper mineralization does not extend into the overlying Gros Cap gneiss, except for the presence of occasional vein-type specular hematite associated with crosscutting quartz veins in the brecciated zones. Surface grab samples collected by Falconbridge for whole rock geochemistry and metal assays indicate Cu up to 0.5 wt%, with occasional gold values up to 2 g/tonne, and silver up to 4.2 g/tonne. Falconbridge did not resample the known historical trenches from the main copper showings. Historical grab samples collected by prospector F. Racicot from the main mineralized zone of the property reportedly averaged greater than 1 wt% Cu, and contained between 24 and 373 ppb Au. The report by W. H. Thompson for Kennco Explorations (Canada) Limited, December 1966, indicates surface trench assays of up to 2.93 wt% Cu over significant widths. Assay results from historical drilling also indicate good values, with grades of up to 3.4% Cu and 0.9g/tonne Au over 11.59 metres that included 4.02 23

wt% Cu over 9.45 meters reported for hole KO-65-01. Drilling by Amerigo in 2002 (see below) did not specifically test this intersection. However, hole IC02-01, collared about 160 metres north of KO-65-01, intersected 1.52% Cu over 8 metres. Assaying for gold in the historical drilling was not carried out consistently. Additional significant assay results from the historical drilling are listed in Table 3. Other mineralization historically reported from the Island Copper property comes from Highland-Crow. Their sampling indicated several quartz veins on the eastern side of the property with elevated Zn and Pb values. Surface samples taken by Falconbridge were unable to reproduce these results, however, it is unlikely that Falconbridge sampled the same material. Several other copper showings have been reported in the vicinity of the Island Copper property, and one radioactive occurrence is reported about 1 km south of the property.

10. Exploration of the Island Copper Property Since signing the option joint venture agreement with Falconbridge in January of 2002, Amerigo has carried out an airborne magnetic survey, a diamond drilling program and an MMI soil geochemistry survey.

10.1 Drilling A four-hole diamond drill program was undertaken during November and December of 2002. A total of 992 meters was drilled in four holes numbered IC02-1, IC02-2, IC02-3 and IC02-4. The drill program was designed to test the depth extent and continuity of previously outlined copper and gold mineralization, and to test chargeability and residual gravity anomalies. The results of the drilling program were described by Camier and Moss, 2003 and are summarized below. The locations of the holes drilled by Amerigo, as well as the location of the historical drillholes, can be found in Figure 7. The following subsections describe the geology and mineralization observed within the drill holes. A long section for holes IC02-1, IC02-2 and IC02-3 is given in Figure 8.

Assays of Cu, Ag and Au are summarized in Table 4. Diamond drill logs are attached in Appendix 1 and assay certificates are in Appendix 2. 10.1.1 DDH IC02-1 Diamond drill hole IC02-1 is located on L89+00N at L99+80E at the summit of the hill above the historic adit. Azimuth of the drill hole is 265° and inclination is -50° from the horizontal. Total depth of the drill hole is 418 metres. The hole was collared into brecciated and mineralized alkali granite under 3 metres of glacial and swampy overburden. The first unit encountered within the drill hole consists of brecciated albite-rich granite with a veined matrix of specular hematite and chalcopyrite ± pyrite, alternating with amphibole ± chlorite veins. The unit extends from 3.00 metres to 12.13 metres. The fracture breccia is comprised of subhedral to euhedral whitish-pink albite plagioclase phenocrysts set in a pink aphanitic quartzo-feldspathic groundmass. The albite phenocrysts are randomly oriented, fractured and occasionally corroded on their edges. They display well-formed polysynthetic twining visible on crystal faces with the naked eye. Local weak to moderate hematite ± K alteration, most prominent along fractures, imparts localized reddish-brown colouration to the granite. The matrix consists primarily of metallic, silver-coloured specular hematite that forms anastomosing veins and veinlets supporting the brecciated fragments of alkali granite. The predominantly specular hematite occasionally contains reddish-brown earthy hematite that often rims some fragments and coats late fracture walls. Sulphide minerals consisting of chalcopyrite and pyrite alternate with hematite in the matrix. Chalcopyrite locally forms up to 10% of the rock, occurring as anhedral blebs, veins and veinlets that often rim granite fragments. It is intergrown with up to 2% pyrite and trace amounts of bornite. Pyrite generally occurs as aggregates of subhedral to euhedral grains within the matrix. Below 4.5 metres up to 1% sulphides occur, but appear to diminish with depth. It was observed that as pyrite increases in the matrix, chalcopyrite decreases, and as chalcopyrite increases, pyrite decreases. Both chalcopyrite and pyrite were also observed as blebs within granite fragments. Occasionally alternating with the hematite and sulphide matrix, are veins and veinlets of moderately to intensely chloritized amphibole. Pyrite as euhedral grains and aggregates was

the only sulphide observed associated with the amphibole schist. The section between 3.0 and 10.0 metres contains the bulk of the copper mineralization. The upper one meter of the unit between 3.0 and 4.0 metres contains 4.9% Cu, which decreases to 3.9% Cu between 4.0 and 5.0 metres. From 5.0 to 11.0 metres the Cu grade drops to an average of 0.5% over the 6 metres. Average grade between 3.0 and 11.0 metres is 1.52% over 8 metres (Table 4). The section also includes gold values of 0.5 g/t over 3 metres between 3.0 and 6.0 metres depth. The lower section of the alkali-granite contains a late fracture that is filled with calcite-rich fault gouge and finely comminuted Iron-oxide altered reddish-brown alkali granite fragments supported by the calcite minerals. The fault crosscuts the core between 10.70 and 10.88 metres at 35° to the core axis. This fault marks the lower contact and trends 50° to the core axis. The walls of the fault contain intensely chloritized amphibole schist and white quartz veining. Gros Cap granite gneiss breccia occurs between 12.13 and 52.22 metres. It is comprised of fracture brecciated granite gneiss alternating with crosscutting zones of greenish-black chloritized amphibole schist. Within the schist are occasional gneissic fragments and discontinuous vermicular veins of quartz and an unknown mineral that exhibits intense pink to reddish-pink potassic alteration. The section is further crosscut by numerous quartz-filled fractures and quartz-vein stockwork containing occasional clots of specularite and chalcopyrite mineralization. Some veins contain earthy-red hematite staining along fracture walls. Pyrite mineralization was observed in the schist as subhedral to euhedral aggregates and individual crystals. Between 52.22 metres and 62.59 metres is a brecciated iron oxide and potassium altered alkali granite that has a sharp upper contact with the brecciated gneiss. This contact is marked with slickensides and weakly chloritized amphibole schist. The alkali granite contains angular to subrounded fragments composed of subhedral, broken phenocrysts of albite plagioclase supported in a pink to red hematite and potassium altered quartzofeldspathic groundmass. The fragments are matrix to clast supported, with a matrix of finegrained amphibole schist and quartz veining. Sulphides occur as chalcopyrite and pyrite up to 1% locally. Chalcopyrite mineralization consists of anhedral grains and blebs occurring in the matrix and groundmass

31

of the fragments. Pyrite forms crosscutting veins and veinlets of subhedral to euhedral granular aggregates. Copper mineralization within this section grades 0.28% over 6.37 metres, between 56.22 metres and 62.59 metres (Table 4). Gros Cap gneissic breccia occurs between 62.59 metres and 94.32 metres, 101.60 metres and 150.19 metres, and 152.62 metres and 252.00 metres. The gneissic breccia is described above. Mineralized gneissic breccia crosscut by high angle (subparallel to core axis) quartz veins occurs in the lower section from 62.59 to 94.32 metres. The quartz veins are comprised of white to translucent quartz and contain minor anhedral blebs and veinlets of chalcopyrite. Copper mineralization grades 0.27% over 1 metre, between 86.25 metres and 87.25 metres, and 0.20% over 2.75 metres, between 90.25 metres and 93.00 metres. Overall, the quartz veined section has elevated copper mineralization of 67 ppm to 2678 ppm between 86.25 metres and 94.32 metres (Table 4). An iron-oxide and biotite-rich lamprophyre dike crosscuts the gneissic breccia between 94.32 metres and 101.60 metres. The unit is black, fine to very fine-grained, exhibits moderate to strong magnetism and is crosscut by numerous earthy-red hematite and white medium-grained calcite veins that trend at 50° to the core axis. The upper and lower contacts are marked by calcite alteration extending over 1 metre into the lamprophyre at either contact. Copper mineralization grades 297 ppm from 94.00 and 95.00 metres and 67 ppm between 95.00 and 96.00 metres (Table 4). Between 150.19 metres and 153.62 metres, a fine-grained greenish-black nonmagnetic, weakly to moderately chlorite altered diabase dike crosscuts the gneissic breccia. The upper contact is sharp, while the lower contact is marked by a friable fault gouge comprised of sand and gravel fragments including diabase and calcite. Occasional subangular xenoliths of gneiss are caught within the diabase groundmass. These xenoliths display alteration rims of up to 5 mm and are intensely iron-oxide altered to a reddish-brown. Primary gneissic textures in the fragments are well-preserved. The bottom of the hole at 252.00 metres consists of fracture brecciated gneiss crosscut by a quartz vein stockwork. No sulphide mineralization was observed in the quartz veins.

10.1.2 DDH IC02-2 Diamond drill hole IC02-2 is located at L88+00N and L100+30E. The azimuth of the hole is 085°, inclination is -50° and total depth is 257.0 metres. The drill hole is collared in Gros Cap granite gneiss breccia under 3 metres of glacial overburden. The gneissic breccia extends from 3.00 metres to 65.30 metres. It is comprised of iron oxide and potassium altered, and silicified fracture brecciated gneiss with alternating matrix and clast-supported sections. The matrix is composed of greenish-black moderately chloritized amphibole schist, forming anastomosing veins and veinlets in the clast-supported sections. Matrix-supported sections contain angular fragments of gneiss up to 2 cm in diameter that are generally less poorly sorted and comminuted. Sulphide mineralization occurs as granular aggregates of subhedral to euhedral grains of pyrite and pyrrhotite supported wholly within the amphibole matrix. Iron-oxide rich alkali granite occurs between 65.30 metres and 95.87 metres. The upper 50 cm’s of the contact is friable and intensely blocky, comprised of sand, mud, gravel and angular fragments of alkali granite and gneiss surrounded by calcite mineralization. The alkali granite is comprised of subhedral to euhedral white to pink albite plagioclase phenocrysts that exhibit well-defined visible albite twinning. The phenocrysts are set within a fine-grained to aphanitic, quartzo-feldspathic pink to reddish-brown fracture brecciated groundmass. Hematite alteration within the granite is either pervasive or occurs as wispy tendrils of reddish-brown alteration fingering into the pink silicified groundmass. Occasional pink potassium feldspar phenocrysts are intergrown with the plagioclase. Rounded quartz eyes were observed scattered throughout the groundmass. The matrix of the fracture brecciated granite is platy metallic-silver specular hematite and earthy-red hematite, alternating and occasionally intergrown with anastomosing veins and veinlets of chloritized amphibole schist. Sulphide mineralization consists of pyrite and chalcopyrite (locally up to 2%) and trace pyrrhotite. Pyrite occurs as subhedral to euhedral grains forming veins, veinlets and granular aggregates within both the hematite and amphibole schist matrices. Chalcopyrite occurs as anhedral grains in the groundmass of the granite and as veinlets, veins and blebs within the matrix. Pyrrhotite occurs as subhedral to euhedral grains randomly scattered in the amphibole matrix. Copper mineralization within this section grades 0.35% between 80.0 and

33

81.0 metres (Table 4). Heterolithic fault breccia occurs between 95.87 and 117.48 metres, 118.24 and 172.73 metres, 174.40 and 197.30 metres, 199.82 and 208.04 metres, and from 221.40 metres to the end of the hole at 257.00 metres. The breccia is comprised of comminuted, matrix supported, rounded to angular, silicified, grayish Gros Cap granite gneiss fragments intermixed with rounded to angular fragments of pink alkali granite. Variable intensities of iron oxide and potassic alteration affect all the fragments, and the gneiss is identifiable by still visible gneissic layering. The breccia commonly grades into zones of intensely altered fragments supported in chloritized amphibole schist. Chlorite alteration of the schist varies from weak to intense. No sulphides were visible in the matrix or fragments. These heterolithic breccias exhibit textures and alteration features that are similar to diatreme breccias. A strongly magnetic, fine-grained, black to dark-gray lamprophyre dike crosscuts the heterolithic breccia between 117.48 and 118.24 metres. No sulphides are associated with this unit. Between 172.40 and 174.40 metres a weakly to moderately magnetic, fine-grained greenish-black to dark-gray diabase dike intrudes the breccia. It contains numerous rounded xenoliths of heterolithic breccia supported within the groundmass. The unit is crosscut by numerous calcite ± quartz veins and veinlets that plunge between 75° and 90° to the core axis. A similar unit was noted between 197.30 to 199.82 metres. A significant discovery in this drill hole was the intersection of an iron- and potassium-metasomatized, reddish-brown quartz-feldspar porphyry (QFP) that appears similar to the Keweenawan-aged iron- and potassium-metasomatized quartz-rich felsic intrusives observed along the Lake Superior coastline near Mamainse Point. The upper contact is sharp with a two centimetre chill margin extending into the QFP and one centimetre of amphibole-rich alteration. The reddish-brown QFP is comprised of fine to medium-grained feldspar phenocrysts alternating with 1-3 mm rounded quartz phenocrysts (~20 to 30%) set in a fine-grained, sugary-textured iron- and potassium-metasomatized groundmass. The feldspars alternate with ragged greenish amphibole clots. Occasional veinlets of chlorite ± epidote emanate from the amphiboles. Sulphides are occasionally associated with the amphibole clots. Very-fine veinlets of reddish-brown hematite surround the quartz grains and occasionally intrude into the grains along minute fractures or crystal faces. A three metre section of the unit is intensely bleached and altered by amphibole ±

34

chlorite and/or epidote alteration, imparting a pale green to green-black colour to the rock. Sulphide mineralization consists of 1 to 5% pyrite and trace chalcopyrite. The pyrite is intimately associated with the amphibole clots in the groundmass. Chalcopyrite was observed associated with the pyrite, as occasional anhedral blebs along the edges of amphibole, and as minute anhedral blebs within the groundmass. The QFP exhibits only background copper levels of between 13 to 110 ppm (Table 4). 10.1.3 DDH IC02-3 Diamond drill hole IC02-3 is located at L91+00N and L99+35E. The hole was drilled at 90° to a total depth of 243.0 metres. The hole was collared in a diabase dike under 2.10 metres of overburden. The unit is comprised of fine-grained, black to dark gray, strongly magnetic and weakly chloritized diabase. No visible sulphides were observed within the unit. The unit has a sharp lower contact at 5.87 metres. Brecciated iron-oxide rich alkali granite and granite gneiss were encountered between 5.87 and 46.08 metres. Angular to subangular fragments of breccia and comminuted materials are clast to matrix supported. The matrix is composed of weakly to moderately chloritized amphibole schist forming anastomosing veins and veinlets. Quartz forms a stockwork of veins and veinlets that crosscut the section. Late calcite veins also form a stockwork that cuts both the breccia and quartz. Calcite veins comprise 5-10% of the section. The walls of both the quartz and calcite veins are coated with earthy red hematite and occasional specularite. Late anastomosing hematite veins crosscut the entire section. Alkali granite fragments contain subhedral to euhedral, fractured and occasionally ragged, pink to white-pink albite phenocrysts with well-developed twinning set in a pink to reddish-pink quartzo-feldspathic groundmass. The groundmass is weakly to moderately Feand K-altered. Occasional specks of sulphide minerals were observed within the groundmass too small to be identified. The granite gneiss fragments contain plagioclase, potassium feldspar and quartz, and still exhibit primary gneissic layering. A well-developed fabric allowed easy identification of the gneiss. Neither the fragments nor the matrix display any evidence of gneissic layering. Intense pervasive and turbid iron oxide and potassium alteration was observed in some of the granite gneiss fragments, and well-defined gneissic layering is still preserved in some reddish-brown clasts. Sulphide mineralization within the sections consists of trace to 5% pyrite, trace to 4%

35

chalcopyrite and trace amounts of pyrrhotite. Pyrite occurs as subhedral to euhedral grains and aggregate clusters within the matrix. Chalcopyrite occurs as anhedral blebs and discontinuous veins and veinlets within the matrix and occasionally in the alkali granite fragments. Some blebs were observed within the gneiss; however, these were always associated with fractures emanating off the matrix into the fragment. Copper assayed at 0.53% over 1.5 metres between 7.50 and 9.00 metres. A crosscutting, non-magnetic, weakly-chloritized, fine-grained, greenish-black diabase dike occurred between 46.08 and 58.98 metres. The unit is crosscut by a sulphide vein composed of pyrite and chalcopyrite. Fragments of gneissic breccia are contained within the lower margin of the dike, and still have a recognizable fabric. Two other diabase dikes occur between 73.64 and 78.00 metres, and 88.38 and 107.74 metres. Both units exhibit a weak to moderate magnetism, are greenish-black, fine-grained and weakly to moderately chloritized. Trace pyrite and pyrrhotite occur as grains within the groundmass. Brecciated Gros Cap granite gneiss occurs at 58.98 to 73.64 metres, 78.00 to 88.38 metres, 107.74 to 227.90 metres, and 231.98 to 241.19 metres. The breccia consists of angular to subangular fragments of gneiss with well-developed gneissic layering in clast and/or matrix-support. The matrix is comprised of fine-grained, weakly to moderatelychloritized amphibole schist. Breccia fragments display varying degrees of weak to moderate iron oxide and/or potassic alteration. A number of fragments exhibit pervasive and intense iron-oxide alteration, with very little trace of the original protolith. Discontinuous broken veins of very-fine-grained, iron-oxide altered reddish-brown unidentified silicified material was observed within the matrix. This material was also observed periodically in some sections of the clast-supported breccias. Sporadic, intense sericite alteration is visible as bleached units up to 10 cm wide below 175 metres. The greenish-black to black matrix forms anastomosing veins and veinlets in the clast supported sections. In matrix-supported sections, fine-grained matrix minerals comprise nearly 60% of the rock with narrow sections up to 85%. These sections contained comminuted angular fragments of gneiss that average 1 to 2 mm in diameter with occasional larger fragments. Careful examination by hand lens reveals a gneissic fabric. However, some fragments do not exhibit any fabric, are fine-grained and intensely iron-oxide altered. These zones are interpreted to be mylonites. Several sections within the breccia appear to be

36

entirely comprised of amphibole schist and contain no fragments whatsoever. These sections are interpreted as fault gouge, and generally are under a metre wide. However, a 4.08 metre wide section occurs between 227.90 and 231.98 metres. A number of these sections are ironoxide altered and silicified. Quartz veins and veinlets crosscut the breccia and schist at varying degrees of 30° to 50° to the core axis. The veins on occasion form anastomosing stockworks and are generally between 1 to 5 mm in width, although some veins were up to several centimetres wide. The abundance of quartz veins decreases substantially with depth, and only occur as infrequent veinlets below 195.00 metres. Quartz veins up to three centimetres wide reappear abruptly between 227.90 and 231.98 metres. Quartz flooding begins at 241.19 metres and intensifies to the bottom of the drill hole. Locally the quartz stockwork supports angular fragments of amphibole schist and Fe-O ± K-altered fragments. No sulphides were observed in this unit. Calcite veins up to three centimetres in width crosscut the breccias, matrix and quartz veins. However, with increasing depth, the calcite veins trend parallel to the quartz veins. The calcite veins also decrease in abundance with depth. Sulphide mineralization occurs only within the matrix, consisting of pyrite, pyrrhotite and chalcopyrite. Pyrite varies from trace amounts to 3% locally, as subhedral to euhedral grains, aggregate clusters, and occasional veinlets. Pyrrhotite occurs in trace amounts, primarily as individual subhedral to euhedral grains and occasional aggregates. Chalcopyrite occurs only as trace amounts forming sporadic anhedral blebs in the matrix. 10.1.4 DDH IC02-4 Diamond drill hole IC02-4 is located at L88+96N and L94+54E and was drilled vertically to a total depth of 239.5 metres. The hole collared in silicified Gros Cap granite gneiss breccia under 4.0 metres of glacial and muskeg overburden. The gneissic breccia is comprised of angular to subrounded fragments of granite gneiss with well-preserved gneissic layering. The mostly gray-white to reddish-brown gneiss fragments are comprised of plagioclase and potassium feldspar phenocrysts alternating with rounded quartz grains (20%) set in a quartzo-feldspathic groundmass. Feldspar phenocrysts exhibit turbid iron-oxide alteration. Fragments are matrix to clast-supported in silicified and weakly chloritized, veryfine-grained amphibole schist. The matrix forms anastomosing veins and veinlets and contains numerous angular clots of calcite mineralization. Quartz veins that crosscut the core 37

between 30° and 90° to the core axis, are between 1 to 5 mm wide, and form a stockwork within the unit. The lower contact at 41.80 metres is marked by an eight centimetre wide fault gouge composed of clay, mud and sand. Between 41.80 and 45.00 metres a brecciated ultramafic intrusion crosscuts the granite gneiss. It is comprised of angular to subangular black to greenish-black, non-magnetic soft fragments hosted in a quartz and calcite vein stockwork. Late, earthy hematite filled fractures up to 3 mm wide crosscut the unit subparallel to the core axis. The lower contact is undefined and gradational into a diabase dike that extends to 56.93 metres depth. The greenish-black diabase is weakly chloritized containing greenish-gray clots supported in the fine-grained groundmass. The lower contact is marked with intense quartz flooding over 10 cm’s, supporting angular fragments of mafic material and gneiss. Silicified Gros Cap gneiss breccia occurs between 56.93 and 92.86 metres, 183.20 and 202.13 metres, and between 210.20 and 212.88 metres. The silicified breccia and matrix minerals are as described above. Similar quartz and calcite veins crosscut the Gros Cap breccia. Up to 3% sulphide mineralization within the Gros Cap breccia consists primarily of pyrite and trace amounts of pyrrhotite and chalcopyrite. Pyrite occurs as euhedral grains forming granular aggregates, occasional veins, veinlets, and individual crystals within the amphibole matrix. Pyrrhotite occurs as subhedral to euhedral grains scattered randomly in the matrix and as very sporadic anhedral granular clusters. Sulphides occasionally rim breccia fragments. Fine to medium-grained diabase dikes crosscut the breccia between 92.86 and 183.20 metres, 202.13 and 210.20 metres, and between 212.88 and 239.50 metres. The weakly to moderately magnetic, greenish-black diabase is generally massive, exhibits a “salt and pepper” texture, is weakly chloritized, and contains trace amounts of pyrite, pyrrhotite and chalcopyrite. Anastomosing quartz and calcite veins and veinlets crosscut the diabase. Lithologic contacts with the gneissic breccia are marked by a stockwork of intense quartz and calcite flooding. These veins generally contained angular fragments of both gneiss and diabase.

10.2 Airborne Magnetic Survey 10.2.1. Survey Specifications and Approach During February 2003, Fugro Airborne flew a detailed aeromagnetic survey over Amerigo’s Sault Ste. Marie area properties. Approximately 140 line kilometres were flown over the Island Copper Property (Figure 2) as part of a larger survey consisting of 1,136 line kilometres. The survey was flown on a traverse direction of 40.5º and at a line spacing of 100 meters. Survey information is summarized in Table 5, and full details of the survey are given in the Fugro Airborne Surveys report included as Appendix 3. The instruments installed in the aircraft are listed in Table 6 and described in Appendix 3.

10.2.2. Survey Results The results of the survey indicate that the Island Copper property is characterized by moderate to high magnetic intensity, with higher intensity areas generally found in the south of the property (Figure 7). Sedimentary rocks of Huronian age immediately to the south of the Island Copper property show moderate to low magnetic intensity. The contact between these sedimentary rocks and the Archean-aged gneiss is not associated with an abrupt change in magnetic intensity, but appears more diffuse. The main magnetic feature of interest on the property is an approximately east-west trending magnetic high (Anomaly A) that originates near the intersection of Highways 552 and 556 (Figure 7). This anomaly is sub-parallel to, and immediately south of, the gravity anomaly outlined by Falcobridge (Mumin and Camier, 2002). Several magnetic lineaments trending northwest to north-northwest most likely indicate the presence of mafic dikes and/or faults. 10.3 Mobile Metal Ion Soil Geochemistry A mobile metal ion (MMI) survey was undertaken over an area covering the coincident gravity and chargeability anomalies outlined by Falconbridge and the linear magnetic anomaly resulting from the Fugro Airborne survey. Samples were taken at an 80 metre station interval between 87+00E and 102+00E on nine lines beginning at L84+00N and ending with L94+00N. Assay certificates are included in Appendix 4. The MMI survey successfully detected the known copper mineralization around the hilltop showing, and outlined an additional four anomalous areas for follow up (Figure 10). The most anomalous Cu response occurs in the vicinity of the hilltop showing where seven samples show response ratios greater than 10, with a high of 28,400 (Anomaly A). MMI response ratios are the preferred method for displaying the results of MMI surveys, and are calculated by dividing each sample value by a predetermined background value for that element. The background is taken as the average of the lowest quartile (25%) of the data (Wamtech, 1996). Anomaly A extends further north on lines 92+00N, 93+00N and 94+00N and is open to the east, north and south. The anomaly is coincident with the strongest chargeability anomaly on the property. Elsewhere on the grid, four samples show Cu response ratios greater than ten. Two of these samples occur on adjacent lines (Anomaly B) and are accompanied by two samples with response ratios greater than 5. Anomaly B is

40

partly coincident with a strong gravity response. Anomalies C and D are linear anomalies associated with, or adjacent to, weak to moderate chargeability anomalies. Anomaly E, which consists of 6 samples with a Cu response ratio of between 5 and 10 over 400 meters, is partly coincident with a gravity anomaly and a weak chargeability anomaly.

11. Sampling Method and Approach 11.1 Drill Core During the drilling program, 223 samples were collected from halved drill core and ten quality control samples were added during the packing of the samples. All samples were marked for splitting and sample numbers attached to the sample interval. The core was then split in two by a mechanical splitter, fitted together and placed back in the core box with the corresponding sample number for that interval. Samples that shattered when split were fitted together as best as possible and returned to the core box for the sampling procedure. The core splitter and the trays that captured the split core were cleaned and swept after every interval. Samples were collected from the core boxes after several boxes had been split, and bagged with the corresponding sample number for that interval. Where possible, the core sampled for assay was removed from one contiguous side only, with the remainder of the core left in the core box for future reference. All samples were put in individual sample bags with the corresponding sample number for each sample interval, and taped closed with clear packing tape.

11.2 Soil Samples Sampling of soil during the MMI survey followed the procedures outlined in the MMI Manual (Wamtech, 1996). Based on the results of an orientation survey at Amerigo’s Coppercorp property, soil was sampled at a consistent depth of 10cm below the surface organic matter. Samples were collected with a garden trowel, sieved to –2mm in a plastic sieve and stored in “ziplock” plastic bags.

12. Sample Preparation, Analyses and Security 12.1 Drill Core All securely packaged split drill core samples were packed into rice bags, approximately 25 samples per bag, and shipped via Greyhound bus from Sault Ste. Marie to Activation Laboratories, 1336 Sandhill Drive, Ancaster, Ontario, Canada, L9G 4V5, for analysis. Each core box was fitted with a lid and secured with 6 centimetre wood screws. The core boxes for each drill hole were strapped together onto a pallet with ¾ inch metal strapping for storage. The drill core is stored on the Island Copper property in a locked quarry enclosure, leased from the YMCA by DCI Investments of Sault Ste Marie, located across Highway 556 from the historic adit. 12.2 Soil Samples All soil samples were put in individual zip lock bags with the corresponding sample number, and securely closed. Samples were packed into rice bags, approximately 30 samples per bag, and transported directly to SGS Canada Inc., 1885 Leslie Street, Toronto, Ontario, Canada, M3B 2M3, for analysis. SGS Canada Inc is an analytical laboratory that is accredited to international quality standards (ISO Guide 17025 accreditation). All samples were analyzed for Cu, Pb, Zn and Cd by inductively coupled plasma/ mass spectrometry following a multi-component extraction. The writer verifies that all samples for analysis were collected and packed under his supervision, and delivered directly to the laboratory by him. The values given here are as reported by SGS Laboratories, and assay certificates are included in Appendix 4. It is the author’s opinion that all sampling was undertaken in a manner consistent with industry practice, and that the samples collected were representative of the material sampled. Every effort was made to keep contamination to a minimum during sampling.

13. Data Verification Amerigo monitors the quality of the analyses received by the introduction of certified reference standards and duplicate samples into the sample stream. Standards are obtained from CANMET Mining and Mineral Sciences Laboratories in Ottawa, Ontario. Duplicate samples are collected in the field (field duplicates) and are also routinely taken from splits of samples by the laboratory (lab duplicates). A summary of standard and duplicate samples

44

used in the drilling program and in the MMI Survey is given in Appendix 5. Another important component of a quality-monitoring program is check assays, whereby samples analyzed at one laboratory are “checked” by a second analysis at a different laboratory. No check assays have been carried out on Island Copper samples to date, since the exploration program is still at an early stage. The author believes that the data reported by Amerigo Resources Limited has been adequately verified, within the scope and purpose of the analyses performed during the exploration program. The data referred and relied upon for interpretation and conclusions is appropriate within the limitations stated. 14. Interpretation and Conclusions Geological mapping has identified an area of gneissic breccia, referred to as the Gros Cap Gneiss Breccia, which is up to 1 kilometre in width and over two kilometres in length with the long axis trending in a north-easterly direction parallel to the Island Lake Fault. The gneissic breccia can be classified as a cataclastic rock which varies from a protomylonite with partially developed fluxion (flow) structure, to a microbreccia containing larger granitoid fragments. The composition of the Gros Cap Gneiss Breccia is quite variable ranging from a leucocratic granitoid or gneissic rock to a mesocratic-to melanocratic chlorite amphibole schist. Within the main mass of Gros Cap Gneiss Breccia are a number of areas consisting of silicified, albitized granite and albite granite breccia, the largest of which is about 300 metres in diameter and is situated approximately 300 metres northwest of the intersection of the Island Lake Fault and the Highway Fault. Within this large mass of albitized granite and granite breccia is the main mineralized zone (Hilltop Occurrence). The Hilltop Occurrence is a prominently exposed area at the top of the large hill with steeply dipping terrane to the east and southeast, reflecting the influence of the Highway Fault (scarp) and Island Lake Fault. The main trench is oriented in a NW-SE direction and has exposed a fractured, brecciated and highly altered albitized granite and a granitic protomylonite. Fractures cutting the albite granite and the matrix to albite granite fragments contain comminuted rock grains and form gossans reflecting the presence of chalcopyrite and pyrite mineralization. It appears that mineralized fractures and alteration extends from the

45

trench area into the wallrock, suggesting that the granitic protomylonite has been extensively replaced by silicification, hematization and albitization related to the fracturing and mineralizing event. The presence of a large area of cataclastic deformation represented by the Gros Cap Gneiss Breccia, attests to a significant tectonic event which affected the Gros Cap Gneiss. The northeast orientation of both the Gros Cap Gneiss Breccia and major regional structures such as the Highway Fault suggests that the area represents a zone of repeated weakness in the crust. Later fracturing and brecciation events gave rise to the introduction of mineralizing fluids which resulted in the extensive alteration in the form of albitization, hematization, and silicification of the host rocks, and was accompanied by the introduction of copper and gold mineralization. Areas of intersection by major regional structures such as the Highway Fault and Island Lake Fault would be the likely focal points for the mineralizing event, as reflected by the location of the albitized granite units on the property. Late Proterozoic (Keweenawan-age) reverse movement along regional northeasttrending structures has been documented through the east shore of Lake Superior (Manson and Halls, 1993). This includes major crustal-scale faults to the north and south of the Island Copper Property such as the Mamainse Fault, Haviland Fault, Van Koughnet Fault and Anderson Fault. Reverse movement along the Highway Fault is consistent with others in the immediate area which has been attributed to a late compressional event related to the advent of Grenville Orogenesis from the southeast (Manson and Halls, 1993). This suggests that the late fracturing and brecciation event which gave rise to the mineralizing fluids may represent part of the extensive mineralizing event that gave rise to the Keweenawan-age Cu-Ag-Au hydrothermal systems in the area represented by deposits such as CopperCorp Mine (Richards, 1985) and the Tribag Mine (Norman, 1977). As such, the IOCG deposit model provides the best framework to guide mineral exploration for copper-gold deposits in this area. Exploration on the Island Copper Property has identified an E-W trending residual gravity anomaly (about 0.5 mgals) that partly coincides with an E-W trending magnetic anomaly covering the main area of mineralization. An E-W trending IP Chargeability anomaly includes the mineralized area and coincides with the residual gravity anomaly. The MMI copper anomalies form a main cluster that is about 250 metres wide and

46

750 metres in length (based on the extent of the sampling). The long axis of the main cluster is oriented in a north-south direction and the anomaly appears to straddle the Highway Fault. Diamond drilling has tested the gravity and chargeability anomalies and was successful in identifying additional mineralization northwest and southeast of the historical drilling. The presence of hematite-altered, brecciated granitic gneiss in drill hole IC02-4 indicates that the hydrothermal system extends 500 m west of the limits defined by the previous drilling. Exploration on the Island Copper property over the last 40 years has indicated the presence of copper and gold mineralization associated with brecciated granitic rocks. The exploration has outlined intermittent surface copper and iron rich breccia style mineralization over an area of 430 meters by 290 meters. While the mineralization has yet to be proven economic, recent exploration, guided by a new exploration model, has demonstrated that potential remains for the discovery of more IOCG type mineralization. 15. Recommendations Prior to a second phase drill program, more surface work is recommended in order to help define drill targets. It is recommended that the following work be undertaken in early 2004: 1. Compilation and interpretation of all geological, geophysical, and geochemical data with the intent of identifying drill targets. This work should include a 3-dimensional analysis of all diamond drill hole information, incorporating where feasible, surface information (geology, geophysics, geochemistry). 2. Detailed structural mapping to determine the relationship between mineralization and structure at both the property and mineral occurrence scales. This should incorporate the use of a standardized classification nomenclature suitable for cataclastic rocks (Higgins, 1970). 3. Geochronological age-dating analysis of the albitized granite using K-Ar dating method to confirm the interpreted late-Keweenawan age of the mineralizing event. 4. Extending of grid lines to the eastern property boundary. 5. In-fill MMI survey of all four anomalies at a 20 metre sample interval and extending the sampling to cover the extended grid lines, and to the north and south of anomaly A 6. Stripping and Trenching of MMI anomalies and other significant targets identified in the compilation and interpretation stage.

Camier, M.Sc. 252m Description (colour, grain size, texture, mineralization, minerals, Planar Sample Depth alteration); CA = core axis feature No. Angle Overburden BRECCIATED AND MINERALIZED ALKALI GRANITE Fracture brecciated albite-rich granite with alternating matrixsupported sections of up to 30cm in width. The matrix is composed of hematite (specularite) and sulphide mineralization alternating and locally intermixed with amphibole ± chlorite schist. The matrix of specular hematite forms anastomosing veins and veinlets throughout the fracture breccia and occasionally forms a supporting matrix in finely comminuted breccia. Moderately to intensely chloritized fine-grained amphibole comprises the matrix where hematite decreases or diminishes. The granite is composed primarily of subhedral to euhedral albite plagioclase phenocrysts set in an aphanitic quartzo-feldspathic groundmass that has weak to locally moderate hematite ± K alteration overprint, which imparts a pink to pale reddish-brown colouration to the rock. The sulphide mineralization consists of Cpy (trace to 10% locally) ± Py (trace to 2%) ± Bn (very trace). The sulphides decrease to between trace amounts to 1% below 4.5 metres. Were Py increases, the Cpy appears to decrease. The sulphides are predominantly contained within the matrix and occur as occasional veins, often rimming the fragments. Trace amounts occur within some of the alkali granite fragments as anhedral blebs and appears to be mostly Cpy. A calcite-rich fault gouge occurs between to metres plunging at: This gouge is composed of finely comminuted fragments of reddish-brown Fe-O altered alkali granite fragments supported in a calcite and amphibole ± chlorite matrix.

Brecciated and fracture brecciated granite gneiss alternating with zones of comminuted fault gouge supported in amphibole ± chlorite schist. Pervasive to turbid hematite ± K alteration extends to 28.74 metres. Below this the alteration is weak to sporadic forming occasional discontinuous and wormy veins and intensely altered fragments mixed with weakly altered fragments of granite gneiss. Numerous quartz veins (3 to 5 per metre) crosscuts the section at various angles between 45° and 75° to the CA, with the most prominent at 50° CA. All the quartz veins contain reddish-brown hematite staining along the vein walls extending up to 2-3 mm into the veins. There are occasional clots of specularite and Cpy mineralization (trace to 1% locally), and occasional subhedral to euhedral Py aggregates. The gneiss fragments contain a moderate to intense gneissic layering. The matrix forms anastomosing veins and veinlets separating and occasionally supporting the fragments. There are narrow sections up to 30 cm wide of black to green amphibole ± chlorite schist. Occasional intensely altered reddish-brown to red fragments are supported within the schist. Py mineralization occasionally occurs within the amphibole schist as subhedral to euhedral grains and aggregates. BRECCIATED AND MINERALIZED ALKALI GRANITE Sharp, brecciated and faulted Upper contact The contact is well-defined marked by slickenfibres and chloritized amphibole schist supporting Fe-O and K-altered gneissic and alkali granite fragments. The contact zone is gradational into matrix and clast supported alkali granite fragments supported in a matrix of intergrown amphibole ± chlorite and hematite (specularite).

The contact fragments are composed primarily of subhedral to euhedral pink albite plagioclase phenocrysts with well-defined cleavage planes. The phenocrysts are set in a pink to red tinted, hematite and Kaltered quartzo-feldspathic groundmass. The fragments vary in size from 2-3 cm, are angular to subrounded. Mineralization consists of Cpy and Py from trace to 1% locally. Cpy is occurs as blebs within the amphibole matrix and as anhedral aggregates. Occasional anhedral Cpy blebs were observed within the groundmass of the fragments interstitial to the plagioclase phenocrysts. Py occasionally occurs as aggregate veins crosscutting the matrix and as individual euhedral crystals supported in the matrix. The lower contact is sharp and faulted at: 62.59

GROS CAP GRANITE GNEISS FAULT BRECCIA Upper contact is sharp at: The breccia is similar to the section previously described above between 12.13 and 52.22 metres. The section consists of alternating breccia fragments in matrix to clast-support and amphibole ± chlorite schist (fault gouge). The amphibole schist contains occasional intensely altered rounded red breccia fragments of granite gneiss and comminuted fragments of gneiss. Quartz veins crosscut the section hosting hematite (specularite), Cpy and Py. The Cpy occurs as large anhedral blebs within the white quartz. Cpy also occurs as occasional blebs and crosscutting veins along fractures that emanate off the quartz veins. Py occurs as large subhedral to euhedral blebs within the quartz veins and amphibole schist. Occasional zones of reddish-brown, variably intense and pervasive hematite alteration occurs within the fragments and throughout the section.

GROS CAP GRANITE GNEISS FRACTURE BRECCIA The unit is previously described in detail above in the upper units. The section is primarily fracture brecciated with narrow sections of matrix supported breccia (~10 cm widths). There is less amphibole ± chlorite schist matrix as was observed uphole. Py mineralization occurs between 159.0 metres and 175.5 metres at trace to 1% locally, and between 182.0 to 195.0 metres at up to 2% locally. The amphibole ± chlorite matrix occurs as anastomosing veins and veinlets crosscutting and filling the fractures within the breccia. It also fingers into the breccia as discontinuous and continuous hairline fracture filling and veinlets. Matrix supported fragments are generally smaller than in the upper units, with more rounding and attrition occurring to the breccias. Annealed and silicified matrix and clast supported breccias in a silicified and quartz flooded amphibole matrix form occasional

They exhibit moderate to intense sericite-alteration, are well rounded to subrounded, and occasionally exhibit intense Fe-O and or K alteration. Calcite and white quartz veins crosscut the unit from parallel to the core axis up to 45° to the CA. Some of the cataclastic breccia consists of brecciated quartz veins intermixed with the gneissic fragments. The section becomes more silicified with depth towards the bottom of the hole.

supported breccia. The alkali granite is composed of subhedral to euhedral pink to white-pink plagioclase set in an aphanitic pink quartzofeldspathic groundmass. There is occasional K-feldspar crystals and rounded quartz eyes. The unit may be granite gneiss; however, there is no fabric in the breccia fragments. The matrix is composed of primarily platy specular hematite with localized zones of amphibole ± chlorite forming anastomosing veins and veinlets. The hematite occurs as veins and veinlets supporting the breccia and occasionally replaces the amphibole matrix. Some sections are in complete matrix support with the hematite supporting finely comminute and brecciated fragments. Some evidence was observed that may indicate the alkali granite consists of slivers of brecciated rock juxtaposed against matrix supported granite gneiss. However, there are zones of intergrown amphibole and hematite matrix indicating the amphibole may grade into hematite matrix. Sulphide mineralization consists of trace to locally 2% Py and Cpy with trace amounts of Po. The Py consists of subhedral to euhedral grains and aggregates in the amphibole matrix and occasionally within the hematite matrix. Cpy consist of anhedral grains and aggregates forming veins and blebs within the matrix and occasional as small fragments within the groundmass of the alkali breccia. Po appears associated with the Py as subhedral to euhedral grains in the matrix. The lower contact is sharp along annealed and silicified 44° CA amphibole ± chlorite fault gouge at:

Lower contact is sharp at: 47° CA 46.08 Fe-O RICH ALKALIC GRANITE AND GRANITE GNEISS BRECCIA The unit is composed of a Fe-O rich alkali granite breccia intermixed with granite gneiss (gneissic layering visible) matrix to clast supported in a matrix of amphibole ± chlorite schist and finely to moderately comminuted fragments of host rock. Quartz veins and veinlets crosscut the unit forming localized anastomosing stockworks. Veins are composed of white quartz with occasional earthy hematite coating fracture walls and occasional specularite books. Calcite veins and veinlets crosscut both the breccia and quartz stockwork indicating late to syn injection. Veins are variable crosscutting at between 20° to 40° to CA. The breccia fragments are composed of alkali granite and granite gneiss fragments. The alkali granite is composed of pink to white plagioclase set in a pink, aphanitic quartzo-feldspathic groundmass with weak Fe-O ± K alteration. The gneiss fragments are composed of plagioclase, K-feldspar and quartz that exhibit moderate to locally intense Fe-O ± K alteration that colours the fragments a reddish-brown. Alteration is pervasive to turbid within the breccia. The gneissic breccia displays a very prominent gneissic layering as opposed to the alkali granite fragments which do not display a fabric.

The Py occurs as subhedral to euhedral grains within the matrix and as occasional aggregates or clusters. The Cpy occurs as anhedral blebs and discontinuous veins within the matrix often associated with the Py and as occasional blebs within some of the alkali fragments. Some blebs were observed within the gneiss; however, these were generally located along hairline fractures extending to the matrix. Po is generally closely associated with the Py as subhedral to euhedral non-magnetic or very weakly magnetic grains.

Contact is: 73.64 GROS CAP GRANITE GNEISS FAULT BRECCIA Upper contact is brecciated with fragments supported in diabase. Contact is gradational over 30 cm at: The breccia is composed of moderately to weakly Fe-O ± K altered Gros Cap granite gneiss with a well-defined gneissic layering. The fragments are matrix to clast supported within a black top greenishblack matrix composed of amphibole ± chlorite schist. Chlorite alteration is variable within the schist. Quartz veins trending between 30° and 50° to the core axis crosscut both the matrix and the fragments. Late calcite veins further crosscut the unit subparallel to the CA up to 70° to the CA. The veins occasionally contain angular fragments of the host rock. The matrix is composed primarily of amphibole schist overprinted by chlorite alteration. Minor magnetite grains were observed within the matrix that exhibit a weak magnetism. Calcite blebs and alteration was also observed in the matrix indicated with a weak to violent fizz reaction with 10% solution of HCl.

It was often observed rimming the fragments and progressively invading the interior of the fragments with wispy tendrils following crystal planes and the gneissic fabric. The fragments display a well-defined or visible weak to moderate gneissic layering. However; some of the fragments may have an overprint fabric due to a build up of strain prior to the faulting event. Composition of the fragments under hand lens examination appears to be plagioclase, K-feldspar, quartz and minor hornblende. The fragments are variable in size from less than 1 mm to greater than 20 centimetres. Comminuted fragments occur surrounding the larger breccia pieces and occur supported within the matrix. Very trace amounts of sulphide mineralization was observed as subhedral to euhedral Py ± Po grains occurring within the matrix only. Smaller anhedral blebs of what appeared to be Cpy also occurs both scattered within the matrix and associated with the other sulphides. 78.00 DIABASE INTRUSIVE DYKE – MAGNETIC Sharp faulted contact marked by calcite veining at: 60° CA Moderately to weakly magnetic, black to dark gray fine-grained chloritized diabase dyke with subhedral to euhedral magnetite grains supported in the groundmass. The unit has numerous crosscutting calcite veins and veinlets that plunge subparallel up to 65° to the CA. Trace sulphides of Py ± Po were observed in the groundmass. Lower contact is faulted with intensely blocky core some of which exhibit slicken fibres. No angle was obtained. 88.38 GROS CAP GRANITE GNEISS FAULT BRECCIA AND ANNEALED AMPHIBOLE SCHIST (FAULT GOUGE) No angle obtained on the upper contact.

The gneiss fragments exhibit localized intense hematite alteration ± K, colouring the rock a reddish-brown and overprinting the protolith. There are often wormy discontinuous veins. Numerous calcite veins and blebs crosscut and occur within the amphibole ± chlorite matrix. Sericite alteration was observed in localized sections of up to 10 cm in width, bleaching the rock to a pale white to buff colouration.

The breccia is as previously described above; consisting of comminuted fragments and fracture to angular breccias alternating with amphibole ± chlorite schist. The fragments are composed of granite gneiss with a well-defined fabric (gneissic layering) set in matrix to clast supported amphibole ± chlorite schist. No visible sulphides observed in the upper portion of the unit. Foliation at 122.08 m within the fracture brecciated sections is: Foliation at 131.66 m within the fracture brecciated sections is: Sulphide mineralization occurs below 123.0 metres at trace to 3% locally composed of Py ± Po forming veins and aggregates within the amphibole matrix. There are zones of weak to moderate conductivity indicating at least some of the veins are interconnected within the core. No magnetism was noted in the Po grains. Quartz veins (white to smoky gray) occur within the amphibole schist (fault gouge) and occasionally crosscut the breccia and on rare occasions rim some fragments. Occasional calcite veins were observed generally paralleling the quartz veins. Trace Cpy mineralization occurs along some fractures and was observe in the matrix often rimming and occurring interstitial to the fragments. Below 171.00 metres the core exhibits a weak to moderate magnetism. Magnetite grains (euhedral) were observed primarily in the amphibole matrix. Some Mt grains were observed within some fragments that resemble alkali granite fragments, as were anhedral blebs of Cpy. These possible alkali granite fragments do not display any gneissic layering and are chiefly composed albite grains with well-defined crystal cleavage planes set in an aphanitic pink groundmass.

The alteration colours the breccia to a reddish-brown with turbid and pervasive alteration. Localized sericite alteration occurs within the breccia bleaching the rock to a buff and yellow-pink colour. Quartz veins decrease substantially with depth occurring as wispy veins. The breccia below 180.00 metres is composed of annealed and fracture brecciated gneiss containing alternating sections with sharp contacts of annealed, Fe-O altered and silicified fault gouge. The fault gouge sections are composed of a mixture of moderate to finely comminuted host rock and amphibole ± chlorite matrix. The fracture breccia is composed do granite gneiss with well-defined gneissic layering set in anastomosing veins and veinlets of amphibole ± chlorite matrix. Sericite occurs sporadically as bleached sections, which is very evident in the narrow (up to 10 cm wide) sections of matrix supported breccias. In these narrow sections the matrix minerals generally exceed 45%. 201.94 202.00 Finely comminuted and annealed fault gouge compose of reddish-brown 53° CA fragments of Fe-O altered host rock mixed with amphibole matrix minerals plunges at:

To (m) 4.0 Overburden 41.72 GROS CAP GRANITE GNEISS FAULT BRECCIA Brecciated Gros Cap granite gneiss with weak to moderate fabric (gneissic layering) at 45° to the core axis (CA). The fragments exhibit varying degrees of weak to intense turbid to pervasive hematite alteration. The breccia is predominantly clast supported to locally matrix supported. The matrix (mtx) is composed primarily of silicified to chlorite-altered amphibole schist that is very fine-grained, black to greenish-black in colour. The amphibole schist also forms anastomosing veins and veinlets that appear to be late annealed fracture breccia matrix. There are numerous anhedral to subhedral calcite clots and blebs that occur within the matrix and as an alteration feature in the fragments. Quartz (Qtz) veins and anhedral rounded to oblong eyes at 20-30% occur interstitial to the feldspars (plagioclase and K-feldspar) in the quartzofeldspathic groundmass in the fragments. The veins crosscut the core at various angles from 30° to 90° to the CA. The feldspars are primarily subhedral to euhedral K-feldspars with varying intensities of pervasive and turbid hematite (hem) alteration. The altered pink K-feldspars are reddish-brown. Plagioclase is affected similarly, but is generally yellow-white in colour. 41.80 8 cm fault gouge composed of clay, mud and sand. 45.00 ULTRAMAFIC INTRUSION Upper contact is marked by calcite clots and blebs.

The fragments are composed of black to greenish-black, angular to subangular, that are generally matrix supported. The fragments are non-magnetic, 3-4 hardness on the MOHS scale and occasionally exhibit a platy to schistose texture. There is a well-defined crenulation cleavage within the section that suggests movement post brecciation. The breccia grades into competent rock with no discernable contact in very blocky core. 56.93 DIABASE INTRUSIVE DYKE No discernable upper contact in very blocky fracture brecciated core. The rock is greenish-black to black with greenish-gray clots (chlorite), fine to very-fine grained. Trace pyrite (Py) and pyrrhotite (Po) occur within the calcite ± Qtz filled fractures, which plunge 30° to 75° to the CA. The rock is relatively massive and nondescript resembling the amphibole schist. The lower contact is Qtz-veined and brecciated containing angular to 28° CA rounded fragments of gneissic breccia. 92.86 GROS CAP GRANITE GNEISS FAULT BRECCIA Cataclastic breccia of Gros Cap granite gneiss. White to Pink feldspars alternating with turbid hematite (pervasive) altered feldspars supported in an amphibole ± chlorite matrix that forms anatomising veins and veinlets. Trace Py mineralization associated with crosscutting quartz veins that trend at 18° to 90° to the CA. Quartz veins form an anastomosing stockwork crosscutting the breccia and matrix.

Hematite veins associated with the calcite and quartz veins occur at perpendicular angles to the CA. The hematite occurs as earthy red rouge. Calcite ± quartz veins contain occasional magnetite grains that exhibit a weak magnetism and trace Cpy. The diabase is weakly to moderately magnetic with localized zones that are non-magnetic. The lower contact is brecciated over several centimetres. 183.20 202.13 GROS CAP GRANITE GNEISS FAULT BRECCIA Intensely fracture brecciated contact resulting in extremely blocky core at 33° CA The breccia is hosted within a silicified amphibole ± chlorite matrix that contains trace amounts of Py and Po and very trace amounts of Cpy. The Cpy mineralization occurs as blebs associated with the Py. The granite breccia is composed of angular to well-rounded fragments that exhibit varying degrees of Fe-O alteration ± K-feldspar, that are matrix to clast supported. Quartz and calcite veins crosscut the core at various degrees to the CA 10° to from perpendicular to 10° to the CA. Occasional angular fragments of 90° to gneiss are supported within the quartz matrix. CA Sulphide mineralization occurs within the groundmass comprised of Py, Po and Cpy. The sulphides vary from trace to locally 3%, with Cpy generally as trace. The sulphides form subhedral to euhedral aggregates and individual grains that often rim some fragments. Sections of the breccia contain turbid to pervasive hematite alteration ± Kfeldspar and form discontinuous wormy veins and veinlets that are reddishbrown. The hematite also occurs as specular hematite within quartz veins and as earthy red (rouge) that coats some quartz vein walls. 202.13 210.20 DIABASE INTRUSIVE DYKE The unit is similar to that described between 92.86 to 183.20 metres.

Only trace amounts of sulphide (Py ± Po) mineralization was observed as blebs within the groundmass and within localized zones of brecciation, within zones of alteration and the groundmass. Veinlets of sulphide mineralization (Py ± Po ± Cpy) were observed crosscutting the diabase and within the groundmass. Py is the dominant sulphide mineral, with Po next and very trace amounts of Cpy. The subhedral Po and anhedral Cpy are associated with the Py occurring as interstitial blebs within the subhedral to euhedral Py aggregates. The unit is carbonate-rich with anastomosing veins crosscutting the core, as well as veins and blebs occurring in zones of local brecciation. ** The 195.00 m marker is in the wrong location; therefore the hole is one metre longer than indicated by St. Lambert Forage. The end of box 34 is 194.55m.

INTRODUCTION

From February 5th to February 7th, 2003, FUGRO Airborne Surveys Quebec Ltd. (FASQ) had flown a highresolution aeromagnetic survey on two blocks located in Sault Sainte-Marie, Ontario. The Northern block (figure 1) was flown with traverse lines spaced at 100 meters and oriented N 60o E. The spacing between traverse lines never varied by more than 50% from the nominal spacing over a distance of more than 2 km. Control lines were oriented S 150o E with a spacing of 1,000 meters and presented the same absolute horizontal deviation tolerance. The traverse lines spacing of the Southern block (figure 1) was flown at 100 meters and oriented N 40.5o E. The control lines were spaced at 1,500 meters with an orientation of S 145.5o E. Table 1 presents the specifications of the survey blocks and table 2 outlines the survey area. The nominal survey height was 120 meters above the surface of the ground. The topographic relief in the survey area presented no significant challenge in meeting altitude specifications.

The base of operation was located in the small town of Sault Ste-Marie, Ontario. The field quality control and data processing were performed at the main office in Montreal.

The primary goal of this project was to provide high quality digitally recorded and processed geophysical data in order to assist geological mapping to indicate structures potentially favourable to mineral explorations.

This report describes the survey procedures and data verification, which were carried out in the field, and the data processing, which followed at the office.

SURVEY OPERATIONS

Crew mobilization, from Ottawa to Sault Sainte-Marie, Ontario, with equipment and survey aircraft, occurred on February 1st, 2003. Test flights were carried out from January 28th to February 5th, 2003. The first production flight started on February 5th and the last production flight was flown on February 7th, 2003.

The aircraft’s base of operation was located at Sault Ste-Marie Airport, Ontario. The field quality control and data processing was performed at the main office in Montreal. Preliminary processed data was sent at the end of February 2003. The final processed database, on CD-ROM, was delivered in March 2003.

CALIBRATION AND TESTS 3.1

Bourget/Heading Test

Before survey production starts, a Heading Test was performed over the Bourget calibration range at the nominal survey altitude in two directions. The pre-survey test was flown parallel to the roads (roughly N-S and E-W). The maximum value to be tolerated in each of the two headings is expected to be less than 5 nT. The average difference from the predicted Total Field magnetic absolute value is expected to be less than 10 nT. The test results are presented in appendix A and summarised in Table 3.

Figure of Merit

Aircraft movements induce spurious magnetic fields, which are removed from the magnetic data by the compensator (section 5.2.2). The efficiency of this removal can be evaluated by conducting a test called a Figure of Merit (F.O.M.). The aircraft flies a series of three manoeuvres of ±10o rolls, ±5o pitches and ±5o yaws in each of the traverse and control line directions in a magnetically quiet zone (low gradient) at high altitude. The peak-to-peak amplitudes of the responses obtained on the magnetometer compensated channel are determined for each of the three manoeuvre types and for each of the four directions. The twelve values are then summed giving a total called the Figure of Merit. This F.O.M. must be less than 2.0 nT or corrective action must be taken to minimise these spurious magnetic fields on the survey aircraft. The F.O.M. is determined at the beginning of the survey and repeated monthly or if a major change in aircraft or magnetometer equipment has occurred. The F.O.M. test performed prior to the survey is presented in appendix A and summarised in Table 4.

Lag Test

In order to ascertain the lag between the navigational data (i.e. X-Y co-ordinates) and the total magnetic field, radar and barometric altimeter data, a lag test is performed before the survey begins. For the magnetic data, this was done by flying in two opposite directions over a body creating a sharp magnetic anomaly. Results are presented in Appendix A and summarised in table 5.

5.2.3.2 GPS base station A Trimble 4000 GPS base station and its antenna, located at Sault Ste-Marie Airport, was used during the survey in order to provide data for post flight differential correction of the airborne GPS positional data.

114

5.2.4 Digital acquisition System The Digital Data Acquisition installed in the aircraft was a Geodas system. This system presents a sampling rate of 10 readings/second and can be programmed to accept a wide variety of input types. Analogs were plotted on a GR33A chart recorder. The data acquisition system was synchronized to GPS time through a 1-second GPS pulse. Since the GPS position and UTC are related to the GPS pulse (while data acquisition timing is controlled by the 100-Hz system clock) a precise correlation was maintained.

The GR33A-1 can plot multiple types of analog and digital signals in programmable, multi-channel strip-chart format complete with alphanumeric annotation of information such as signal identification, operating parameters, header messages, fiducial numbers and time. The advantage of an onboard chart recorder is that it is a valid record of the actual recorded data. The horizontal scale was 2 cm per 1 km of ground distance (1:50 000). The vertical scales for the total field magnetometer were 20 nT/cm (fine) and 100 nT/cm (coarse). The vertical scales for the radar and barometric altimeters traces were 100 feet/cm.

5.2.5 Positioning Cameras, Navigation and Flight Path Systems 5.2.5.1 Video System The video system installed in the aircraft was a CDS video surveillance camera connecting to a VHS cassette recorder, model AG-7. The camera lateral field of view was slightly larger than the terrain clearance. The system recorded both video and data. The data, which was displayed alphanumerically in the bottom portion of each frame, included: -

GPS time in hh:mm:ss format Fiducial (seconds)

-

Flight and line numbers

Data and video were available for review immediately after each flight with no further processing.

115

5.2.5.2 Global Positioning System (GPS) Global Positioning System consists (at present) of a constellation of 24 active satellites orbiting the earth. The orbital period for each satellite is approximately 12 hours with an altitude of approximately 20,000 km. Each satellite contains a very accurate cesium clock that is synchronized to a common clock by the ground control stations (operated by the U.S. Air Force).

Each satellite transmits individually coded radio signals that are received by the user’s GPS receiver. Along with timing information, each satellite transmits ephemeredes (astronomical almanac or table) information that enables the receiver to compute the satellite’s precise spatial position. The receiver decodes the timing signals from the satellites in view (4 satellites or more for a 3-dimensional fix) and, knowing their respective locations from the ephemeredes information, the GPS system computes a latitude, longitude and altitude for the user. Theses position solutions are continuous and are updated once per second.

The airborne differential GPS receiver used on the aircraft was a Novatel OEM4. This receiver had an accuracy of ±5 metres and positions were real-time differentially corrected with the Omni-Star system. The GPS receiver was used in conjunction with a Picodas PNAV-2100 navigation system. The main features were: Real-time graphical and numerical display of flight path with survey-area and grid-line overlay

-

Distance-from-line and distance-to-go indicators

-

Operation in survey-grid or waypoint navigation mode Recording of raw range-data for all satellites from both the aircraft-borne and base-station GPS receivers, for post-flight refinement of GPS position

116

5.2.5.3 Altimeters Two altimeters were used to record aircraft terrain clearance or altitude: radar and barometric altimeters. The outputs from the altimeters are a linear function of altitude. The radar is pre-calibrated by the manufacturer and is checked after installation using an internal calibration procedure and also by performing calibration test flights. The altimeter calibration test flight performed is presented in Appendix A.

DATA PROCESSING 6.1

Field Quality Control Procedures

Before each survey flight, all instruments were powered on for at least 30 minutes to ensure electronic stability. 6.1.1 Positioning The GPS receivers, real-time differentially corrected through the Omni-Star systems, in conjunction with the navigation systems, provided in-flight navigation control. GPS data were post-processed daily. The raw GPS data from both the mobile (aircraft) and base station are recovered. Using Grafnav commercial software, positions are initially recalculated from the recorded raw range data in flight. Post-flight recalculation of the fixes from the raw ranges rather than using the fixes which are recorded directly in flight, improves on the final accuracy, as it eliminates possible time tag errors that can result during the real-time processing required to get from the range data to the fixes directly within the receiver. Differential corrections are then applied to the aircraft fixes using the

118

recorded base station data. The resulting differentially corrected latitudes and longitudes are then converted from the WGS-84 spheroid to UTM metres. A point-to-point speed calculation is then done from the final X, Y coordinates and reviewed as part of the quality control. The flight data is then cut back to the proper survey line limits and a preliminary plot of the flight path is done and compared to the planned flight path to verify the navigation.

After each flight, data, including GPS, were transferred to the field computer system and merged into the database. Navigational data were plotted in XY plan format. Errors were noted and re-flights called where necessary.

GPS data from the real-time and post-processed sources were compared with each other and with barometer data. This comparison resulted in the selection of real-time and/or post-processed GPS. A thorough verification of X, Y, Z velocities was then made and jump corrected on-site, producing the final flight path in the field. Jumps were generally inferior to 5 metres.

Lag corrections of TFM were applied in the field. The quality of the GPS and the effectiveness of the lag correction were verified through preliminary grids. Once GPS and lag were confirmed, the final flight path was determined by cutting the line segments at the appropriate control lines.

119

6.1.2 Maintenance of speed and sampling Despite the gentle to moderate terrain, the speed of the aircraft sometimes varied significantly due to prevalent strong winds during the survey. On the survey, the pilot maintained a slow economic cruising speed for the aircraft. This reduced fuel consumption and the time required for repositioning between survey lines. Lowering the speed also increased the sampling density. Figure 3 presents a histogram of the aircraft speed variations. 6.1.3 Maintenance of flight altitude The nominal survey altitude was 100 metres, except in the case of rugged topography where the pilot’s judgement prevailed. The aim was to maintain the altitude difference at the intersections of traverse/control lines below 30 metres. 6.1.4 Diurnal monitoring Diurnal magnetic variations were monitored and recorded using the base station at Sault SteMarie airport. Base station time and aircraft acquisition time were synchronized. The record of variation for the magnetic base was examined for intervals where the variation has exceeded 3.0 nT (peak to peak) from a long chord equivalent to fly the average distance between control lines. This specification was verified in the field prior to demobilisation. Any line or section of line not meeting the specifications were noted for reflight.

6.1.5 Magnetic data Compensation of the observed magnetic data for heading and aircraft effects was accomplished in real time by software controlled digital processing of the raw. Both the raw and compensated data were recorded so that postflight processing could be performed, if required.

All magnetic data recorded in flight was checked for noise by an inspection of the fourth difference trace. The fourth difference is defined as:

4DI = XI+2 – 4XI+1 + 6XI – 4XI-1 + XI-2 Where XI is the Ith total field sample. In this form, the fourth difference has units of nT. High frequency noise should be such that the fourth differences divided by 16 are generally less than ±0.1 nT. The fourth difference was displayed on analog at scales of 0.1 nT/cm. The close inspection of the filtered mag., the 4th difference and noise channel allowed the correction of remaining spikes. To ensure the completeness and veracity of the magnetic data, grids and preliminary magnetic contours were produced, without control line levelling, in the field.

6.2

Office Data Processing

Essentially the office processing system represents the same capabilities of the field system, plus additional presentation and colour plotting facilities. With the increased capacity, personnel and time available, editing and compilation procedures were carried out to detect and correct any remaining isolated errors, to refine the positioning, carry out levelling and gridding through to final contours. The processing stage was monitored closely by the Project Leader. 6.2.1 Positioning All GPS post-processing and jump corrections made in the field were verified.

6.2.2 Compilation of magnetic data

122

A diurnal correction was applied prior to control line levelling. To obtain the diurnally-corrected TMI channel, the long wavelength component was subtracted from the lag-corrected TMI channel. The long wavelength component was deduced by subtracting the average value of the magnetic base from each of the magnetic base value and a 90second low-pass filter was applied.

Also prior to levelling, flight path trimming was verified and finalised. The efficiency of the mag filtering and despiking made on-site was verified.

Intersection levelling was performed in three iterative cycles. Each cycle included: 1) 2) 3) 4)

computation of intersections from raw controls and corrected lines mistie correction model for controls computation of intersections from corrected controls and raw traverses mistie correction model for traverses.

Each cycle used increasingly precise (or with higher frequencies) mistie correction models and greater care in removing erratic intersections (high gradient) through visual inspection.

The first cycle used polynomial (Oasis TREND) model for the controls and the traverses. The second cycle used careful levelling method for the controls. The third and last cycle used the radar intersection errors as a guide to determine intersection removal or edition and to introduce higher frequency content in the correction models. High frequency line-to-line noise was reduced further by using in-house proprietary micro levelling technique.

CONCLUSION

Started on January 28th and ended on February 7th, 2003, the survey was completed inside the estimated time frame.

The noise levels for the measured Total Magnetic Field were well within the accepted limits, as shown by the fourth difference of the lagged, edited airborne magnetic data.

The flight path was surveyed accurately and the speed checks showed no abnormal jumps in the data. The aircraft were able to remain within the ±30 metre elevation differences at the traverse/control line intersections, except in rugged terrain, which was subject to pilot’s judgement.

The calculation of the digital elevation model from the Z-GPS values, provided by the Real Time OMNI Star system, showed that the elevation errors were located in the 5-7 meter range.

It is hoped that the information presented in this report, and on the accompanying products, will be useful both in planning subsequent exploration efforts and in the interpretation of related exploration data.

APPENDIX 5 STANDARDS AND DUPLICATES USED IN QUALITY CONTROL PROGRAM

145

Certified Reference Materials were obtained from Natural Resources Canada at CANMET Mining and Mineral Sciences Laboratories in Ottawa, Ontario. Two different standards were used, KC-1a, a zinc-lead-tin-copper-silver ore and CCU-1C, a copper concentrate. KC-1a consists of massive sphalerite-pyrite ore containing native silver and galena from the Kidd Creek Mine. CCU-1C is a copper flotation concentrate of ore from the Ruttan mine, Lynne Lake Manitoba. Both of these standards have certified values for copper and silver, while CCU-1C also has certified values for gold. Duplicate samples used in the quality control program were collected from outcrop on the Island Copper property. Quality control samples for the drilling program are listed in Table A5-1. Table A5-1.

During the MMI Survey, quality control consisted of analyzing duplicates of different types. Duplicate field samples were collected during sampling on the Island Copper property. Duplicate samples of beach sand, remote from the Island Copper Property, and a mixture of beach sand and Coppercorp tailings were also submitted for analysis. Seventeen laboratory duplicates were also analyzed. Results of analysis of submitted duplicates are shown in Table A5-2, and results of analysis of laboratory duplicates are listed in Table A5-3.
