SUMMARY

The Halcrow property consists of four claims comprising 48 claim units that are located 210 kilometres northwest of Sudbury, Ontario. The claims are held I Q&X* by Cameco Corporation. The claims are situated in the southeast part of Halcrow Township and the northeast part of Tooms Township.

The property was acquired by staking in March 1994 following some regional geological reconnaissance work completed in the southern Swayze greenstone belt as part of the Ontario Generative project. The area was recognized as having many geological characteristics in common with established gold mining camps such as Kirkland Lake and Timmins. The property lies along a regional fault known as the Halcrow-Osway fault which may be related to the Kirkland Lake-Larder Lake Break to the east. This regional structure is characterized by shearing, carbonatization, silicification and sericitization of most lithologies and by the presence of numerous gold showings and one past producer.

Following the staking, a 85 kilometre grid was cut, and a program of geological mapping and sampling was conducted. The geological mapping has confirmed the existence of a high strain (shear) zone which crosses the centre of the property. The lithologies present include coarse to fine clastic sediments, fine grained intermediate to mafic tuffs, mafic volcanic flows and ultramafic intrusives. Within the high strain zone, which is 600-1000 metres wide, alteration intensity has increased with the rocks containing dolomite, ankerite and sericite.

No significant gold occurrences were located as a result of the current program. Sulphide mineralization is restricted to narrow zones within mafic volcanics and occasionally associated with narrow felsic dikes.

The evaluation of the gold potential of this property is greatly inhibited by the extensive overburden cover. Ground geophysical surveys would assist in the interpretation of the bedrock geology. It is recommended that further exploration of the property consist of magnetic and VLF surveys, limited IP/resistivrty surveying and a program of diamond drilling to test geological and geophysical targets.

1.0 Introduction

The Halcrow property consists of four claims comprising 48 claim units and is located in southeast Halcrow Township and northeast Tooms Township about 210 kilometres northwest of Sudbury, Ontario. The property was acquired by Cameco in March 1994 by staking open ground.

The property is situated along the Halcrow-Osway corridor, which delimits a zone of high strain, along with anomalous carbonatization, silicification and locally sericitization. The property lies to the northwest of known zones of gold mineralization in the Hotstone and Betty Lakes areas and to the southeast of an old underground exploration property, known as the Halcrow-Swayze mine. The main lithologies which underlie the area include clastic metasediments, mafic to intermediate volcanic flows and minor mafic to felsic intrusive rocks. A series of Input conductors crosses the properties and is associated with the volcanosedimentary lithologies. Exploration work is hampered in the area due to the extensive glaciolacustrine gravel and sand deposits which cover most of the claim group.

This report covers exploration work done on the Halcrow property by Cameco personnel during 1994, including linecutting, geological mapping and lithogeochemical sampling. The field work was completed by contractors and by Doug Panagapko and Peter Chubb.

2.0 Property Location and Access

The Halcrow property consists of four claims totalling 48 claim units, located in Halcrow and Tooms Townships, about 150 kilometres southwest of Timmins and 210 kilometres northwest of Sudbury, Ontario (see Figure 1). The southern limit of the property passes through the northwest part of Betty Lake, and extends to the northwest to the Kinogama River just south of Halcrow Lake.

The property can be accessed via the Kormack road which leaves Highway 667 about 19 kilometres west of Sultan, Ontario. Another old logging road exits the Kormack road just north of Sylvanite Creek, about 30 kilometres north of the highway. This road proceeds west of Betty Lake and ends at Sawbill Lake. Several overgrown logging roads, suitable for use by ATV provide access to within 300 metres of the northern property boundary. Sawbill Lake provides access to the western part of the grid.

3.0 Land Status

The layout of the claim group is given in Figure 2. The property was acquired by staking in March and April 1994. The work was contracted out to Exsics Exploration of

Timmins and the claims were recorded April 8, 1994. A total of S19,200 in assessment work must be filed by April 8, 1996 to keep the claims in good standing. The claim abstracts may be found in Appendix A.

4.0 Topography and Vegetation

The property lies within the Hudson Bay watershed, about 35 kilometres north of the divide between the Great Lakes and Arctic watersheds. The two largest lakes on the property, Betty Lake and Sawbill Lake, both drain north into the Kinogama River which in turn drains into the northeast flowing Ivanhoe River. The property is largely covered by bouldery till and sand deposits and minor cedar swamps. Poor outcrop exposure is restricted to the eastern half of the property. The western half of the property is almost entirely covered by overburden. In this area, esker ridges are the cause of local rugged relief. Two semi-continuous eskers have been mapped crossing the western half of the property. One esker lies near the eastern boundary of claims 1189290 and 1189287. The other esker crosses through the centre of the same two claims. Both features are oriented approximately north-south.

Vegetation consists of poplar, birch and white spruce in the western half of the property, and more abundant jack pine east of the eastern esker mentioned above. Black spruce and cedar occupy the lower, swampy areas. Refer to Figure 5 for the distribution of topographic and vegetation features.

5.0 Regional Geology

The Halcrow property is located within the Abitibi Subprovince of the Precambrian Shield, specifically in the southwesternmost part of this extensive greenstone belt. The supracrustal sequence is bounded to the east by the Kenogamissi Batholith, to the south by the Ramsay-Algoma gneissic complex and to the west by the Kapuskasing granulite terrain. It is referred to as the Swayze greenstone belt.

The southern part of the Swayze greenstone belt, south of Coppell, Newton and Dale townships, can be broadly subdivided into five main assemblages (after Jackson and Fyon, 1991). These assemblages are: Garnet-Tooms, Hong Kong, Marion, Halcrow- Swayze and Ridout. Of regional significance to the Halcrow property are the Gamet- Tooms, Halcrow-Swayze and Ridout assemblages (see Figure 3).

The Garnet-Tooms assemblage underlies much of Tooms and southern Greenlaw townships. It lies between the Ridout assemblage to the north and a unit of oxide facies iron formation which forms the top of the Hong Kong assemblage to the south. The main rock units which make up this assemblage are tholeiitic basalt, intermediate to felsic calc-

alkalic flows and komatiitic flows with minor oxide facies iron formation. The basaltic rocks are cut by coarser grained diorrtic to gabbroic phases which may be intrusions or coarse flows. Generally, the massive to pillowed tholeiitic basalts form the base of the assemblage and the upper part consists of calc-alkalic feldspar porphyritic basalts and andesites.

Rocks which comprise the Ridout assemblage consist of turbidrtes, arkose and conglomerate with minor interbedded units of metavolcanics and iron formation. The conglomerate contains pebbles of chert, vein quartz, basalt, andesite, porphyritic rhyolite and jasper fragments. The Ridout assemblage underlies part of Tooms, Greenlaw and Garnet townships in the western part of the south Swayze greenstone belt. It is thought that the Ridout assemblage is temporally and technically equivalent to the Temiskaming assemblage in the Kirkland Lake area.

The Halcrow-Swayze assemblage is the most regionally extensive group of lithologies in the southern Swayze belt, underlying the southern parts of Halcrow, Denyes, Swayze, Dore and Heenan townships and much of Garnet and Benton townships. The primary lithologies which make up the assemblage are komatiitic flows, tholeiitic basalt and intermediate to felsic calc-alkalic volcanics interlayered with oxide facies iron formation. The komatiitic to tholeiitic phases tend to occur along the margins of the assemblage with the intermediate to felsic rocks occupying the core (ie. in Denyes and Swayze townships).

The Halcrow property is underlain by rocks belonging to the Halcrow-Swayze and Ridout assemblages. The area covering Tooms and Halcrow Townships was mapped by Donovan in 1965 and this is the only available government mapping for the Halcrow property (Donovan, 1968). During 1993 and 1994, regional geological mapping has been completed over the south Swayze greenstone belt by Kevin Heather of the Geological Survey of Canada (Heather, 1994). Part of the work completed includes geochronological dating of various key lithologies in the area. These data have allowed for a re- interpretation of the overall stratigraphy and structure of the south Swayze area.

6.0 Previous Exploration

Recorded exploration in the property area commenced in 1933 with the discovery of gold 2.8 kilometres northwest of the property. A shaft was sunk to a depth of 371 feet and underground development took place on the 200 and 354 ft levels, during the period 1933-35. A small 25 ton test mill was erected on the site, which became known as the Halcrow-Swayze mine. Gold occurs within a shear zone localized along the contact between greywacke and volcanic tuffs. A narrow quartz diorite dike also lies within the zone of shearing. Pyrite and carbonate are abundant in the gold-bearing parts of the zone. The largest vein examined was 900 ft long, 7 ft wide and averaged 0.12 opt gold.

HALCROW PROJECT - 1994 Exploration Program

It was estimated that the main vein (No. 2) contained 35,000 tons of ore grading 0.17 opt Au. down to the 354 ft level (Rickaby, 1935).

Canadian Nickel Co. Ltd. drilled one hole in 1968, located about 200 metres south of the southern property boundary (BH 31960). Mafic volcanics and tuffs, cherty iron formation and diabase were intersected. The hole apparently tested an EM conductor.

Granges Exploration AB drilled two diamond drill holes totalling 156.0 metres in the westcentral part of the property in February 1977 (SW-5, SW-7). These holes were drilled to test an EM conductor. The holes intersected andesrtic tuffs and graphitic argillite with up to 10^6 pyrite. No gold assays were reported.

In 1981, Granges Exploration AB drilled two additional holes, both located about 600 metres southeast of the property boundary (SW-100, SW-101). These short holes intersected quartz-chlorite schist, andesite and graphitic schists and were most likely testing EM conductors.

The majority of the property was held by Regal Petroleum Ltd. during the period 1984-86. At this time the company completed an airborne Aerodat survey, geological mapping, ground magnetic and VLF surveys, IP/resistivity and soil surveys. Detailed work was concentrated in the vicinity of the Halcrow-Swayze mine. In 1985, the company drilled 14 holes in the immediate area of the mine workings. A further 9 holes were drilled by Regal in 1986. Results of this work were generally disappointing and no further work was completed.

In 1988, Quinterra Resources Inc. completed a large exploration program to the south of the present property. One of the drill holes is located about 500 metres south of the property (SC88-4). It intersected mafic to intermediate tuffs, cherty sediments and an ultramafic flow. The highest reported gold value was 211 ppb.

7.0 1994 Exploration Program

7.1 Linecuttino

During the period May 25 to June 20, a cut line grid was completed over the Halcrow claims. The work was contracted out to Services Exploration Enrg of Rouyn- Noranda, Quebec. A total of 84.85 kilometres of baselines, tie-lines and grid lines were cut and chained. The baseline, oriented at 1300 Az., was started on an old trail where it crosses a creek on claim 1189289. This point could easily be located on 1:20,000 scale airphotos. In order to complete the grid around several small lakes, it was necessary to cut tielines at 5+OOS, 7* OOs, and 13+OOS. Every 100 metre picket was marked with a metal dymo tag for a more permanent record. Figure 4 shows the grid layout.

7.2 Geological Mapping

7.2.1 Introduction

During the period June 8-21, all lines on the newly established grid were mapped and bedrock exposures were located and tied into the grid. In addition to mapping exposed bedrock, topographic features, overburden and vegetation types and claim lines and posts were noted. All location data, lithologies, alteration, mineralization, structure and sample information were entered on a daily basis into Reldlog, a field-based database program which is linked to Autocad. An updated grid and geology map was kept in the field. Once the crew demobilized to Sudbury, paper copies of all datasets could be immediately generated.

The bedrock and surficial geology is given on Rgure 6, located in the back pocket. Sample locations and Reldlog station numbers are given in Rgure 7. Certificates of analysis and whole rock geochemical data may be found in Appendix B. A summary of the geochemical nature of samples submitted for whole rock analysis is shown on Rgure 8. Lithologic descriptions based on whole rock geochemistry are related to Jensen Cation Plots (see Rgure 9 for legend). Individual samples are plotted on Rgures 10 through 13. An additional 17 samples from previous exploration work done by Regal Petroleum are shown on Rgure 8 and the data are also plotted on Rgures 14 and 15.

7.2.2 Lithologies

The Halcrow property is underlain by a varied sequence of volcanic and sedimentary rocks which have been intruded by minor mafic to felsic intusives. Ultramafic extrusive/intrusive rocks are also present on the property. All rocks are of Archean age and have been metamorphosed to the lower to middle greenschist grade.

11From southwest to northeast, the following lithologies have been mapped:

ultramafic intrusive (dunite), mafic volcanic flows (Mg-tholeito'c) with minor gabbro, greywacke/conglomerate, intermediate pyroclastics or fine grained sediments with minor argillite, and mafic volcanic flows (Fe-tholeiitic). Minor felsic intrusives were also mapped. Each of these lithologies will be described in more detail below.

Ultramafic Intrusive (Dunite)

This unit is exposed in the southwestern part of the property, on line 3+OOW and on the road to Sawbill Lake. It is a massive dark green to dark grey rock that is strongly magnetic and contains local concentrations of fibrous serpentinite. On the weathered surface, it has a fractured fine grained appearance that is typical of ultramafic intrusives. These rocks are ultramafic komatiite in composition (Rgure 12) and contain up to S?.?1!!) MgO with anomalous Ni and Cr values (sample HA-9423). A similar unit was intersected in the Quinterra drill hole located at Betty Lake, and may be part of the same sill.

Mafic Volcanic Flow (Mg-Tholeiitic Basalt)

This unit forms a wide band, which in the southcentral part of the grid, attains a width of about 600 metres. Most outcrops are located near the Sawbill Lake road and south of the small lake just north of the road. The unit is comprised of fine grained, moderately foliated dark green basalt flows that contain variable amounts of carbonate, usually calcite. The basalt weathers a rusty brown colour, is non-magnetic and occasionally contains trace amounts of fine grained pyrite. Possible pillows were recognized in one location (1+OOE/9+OOS), although these are not readily identifiable due to the high strain. The basalt is intruded by a small pod of leucogabbro near the 13+OOS tieline. Chemically, the unit is a Mg-rich tholeiitic basalt (Figures 10, 11, 12). Seven samples submitted for whole rock analysis had MgO percentages ranging from 4.65 to S.18% with the majority of the samples averaging Z.7% MgO.

Another thin unit of Mg-tholeiitic basalt is located within the main sedimentary package immediately northeast of the string of small lakes in the centre of the property. It appears to have limited strike length but the area to the east is largely overburden covered. The average MgO percentage for two samples from this unit along with the seven samples mentioned above is 7.96^ Average Fe2O3 percentage for the same suite of samples is 12.03*36.

Greywacke/Conglomerate

Metasedimentary rocks form the most well exposed lithology on the property. This rock type extends from line 15+OOW to the southeastern property boundary and has an average exposed thickness of 500 metres. There are several lithologic units which make up the sedimentary package. Because these rocks have been subjected to high degrees

of strain, rt is often difficult to distinguish between well bedded greywacke and intermediate tuff to lapilli tuff. As well, the exposures are often of limited size. There is generally a northeastwards decrease in clast size from primarily conglomerate in the 5+OOS to 7+0X38 area through greywacke from 5+OOS to the 0+00 B/L.

The conglomerate is polymictic and varies from clast to matrix supported. The matrix consists of fine grained feldspar, quartz and chlorite. It was originally mapped by Donovan (1968) as a clastic sediment. Previous exploration work categorized these rocks as volcanic agglomerates. The clasts have been flattened due to high strain and often contain an abundance of volcanic fragments. Occasionally, rounded granitic clasts were observed which are more typically associated with Temiskaming-type conglomerate. The area between 5+OOS and the 0+OOB/L is underlain by finer grained moderately well bedded greywacke/tuff. It is very difficult to determine the provenance of these fine grained rocks due to their poor exposure. They are medium grey to green on weathered surface and generally have a well banded appearance. From 10+OOE to 11+OOE, just south of the baseline, are several outcrops of grey to black fine grained argillite. This unit is well bedded and may represent the finest grained subunit of the sedimentary package.

Whole rock analysis of some 17 lithologic samples indicate that this package is of a calc-alkaline affinity with calc-alkaline basalt, andesite and dacite equivalents present (Figures 10, 11, 12, 13). In general terms, the calc-alkaline basalt occupies the southwestern part of the sedimentary package while the andesitic and dacitic affinities lie to the northeast.

Mafic Volcanic Row (Fe-Tholeiitic Basalt)

The northeast quarter of the property is thought to be underlain by massive to moderately foliated fine grained basalt, although the outcrop exposure in the area is poor. Where exposed, the basalt is moderately well sheared and contains abundant calcite. Sericite is also found in local concentrations. The outcrops locally exhibit a tuffaceous texture, as is the case at 15+70W/0+75N, where a mafic tuff unit is intruded by a quartz phyric felsic dike. The basalt is non-magnetic and only rarely contains trace pyrite.

As the heading indicates, these rocks have a Fe-tholeirtic chemical affinity (Figure 11,12,13). Percentages of Fe2O3, MgO and TiO2 have the following respective ranges (based on four samples): 13.68-14.09^ S.6-5.95%, and 0.98-1.05"fc.

Gabbro

Only small areas are interpreted to be underlain by gabbroic intrusive rocks. Both gabbro and leucogabbro occur. They are typically medium grained, medium to dark grey-green and exhibit an equigranular massive texture. The outcrop areas are located near 19+OOW/7+50N and 3+OOW/13+OOS. The gabbro is non-magnetic and is

generally devoid of sulphides.

Felsic Dikes

Fine to medium grained felsic dikes are a minor constituent of the bedrock in the area. These dikes are narrow, pink to buff coloured and range in composition from quartz monzonite to granodiorite. Examples of these dikes are found at 1+OOE/9+OOS and 15+70W/0+75N. At this last location, the dike is associated with quartz veining and elevated pyrite percentages.

Mafic Dikes

Although not outcropping, a magnetic mafic dike is interpreted (from vertical derivative magnetic data) to cross the northern part of the property. The dike is part of the Abitibi swarm (1141 Ma) and continues for a distance of 240 kilometres to Lake Abitibi. The dike is oriented at about 0650 and is of undetermined thickness.

7.2.3 Structure

The majority of the finer grained lithologies on the property display a weak to moderate penetrative foliation that has an azimuth ranging from 1050 to 1250. Dips for the most part are steep to the northeast, although some units dip steep southwest as well. Although tops directions have not been observed on the outcrop scale, the general progression from coarse to fine clastic units as you approach the northeast would suggest that the lithologic sequence tops to the northeast, making it a largely upright homoclinal sequence. This sequence is possibly situated on the northern limb of an east plunging antiform, the nose of which lies somewhere in central Greenlaw Township.

Several zones of high strain (locally termed 'shear zones') have been observed on the property. These zones are delineated on Figure 5. In outcrop, the strain is manifested as an extreme fissility in fine grained sediments. In coarser sediments, clasts are stretched in the plane of the foliation. Outcrop exposures were not sufficient to determine if the deformation is due to compression oblique to the foliation or to elongation within the plane of foliation.

7.2.4 Alteration

Several different alteration types are present on the Halcrow property. The least altered rocks are ultramafic intrusives and massive mafic volcanics flows. These units generally contain minor calcite and some late quartz veining. As you proceed in towards the centre of the property, the alteration intensity increases, with the rocks becoming more strongly carbonatized, sericitized and locally silicified. The finer grained

sediments/tuffs are most strongly seridtized, in part due to their more felsic composition. Carbonate alteration is predominantly calcite although in local highly strained zones dolomite and ankerite are the main carbonate minerals.

7.2.5 Mineralization

Sulphide mineralization on the Halcrow property consists primarily of narrow zones of disseminated pyrite and occasional chalcopyrite. One outcrop located at 15+75W/0+75N contains up to IQ/% pyrite concentrated along the contact between a quartz-feldspar dike and a sheared mafic volcanic flow. Sulphide contents are slightly elevated where shearing and alteration increases.

No significant zones of gold mineralization were located on the property. A value of 110 ppb is associated with a sulphide zone along the contact between a felsic dike and sheared mafic volcanics (15+70W/0+75N).

8.0 Airborne Geophysical Surveys

The Ontario Geological Survey released an airborne total field magnetic and electromagnetic survey covering the central and southern Swayze greenstone belt (OGS 1982). The data are available as a series of 1:20,000 combined magnetic/Input maps and 1:31.680 monochrome Input maps. The Halcrow property is located on Map 80540, Vice Lake Sheet.

The magnetic data show a general southeast trend of alternating high and low magnetic layers, in the vicinity of the property. The areas of high magnetism correspond to mafic volcanic flows and ultramafic intrusives. Lower magnetism correlates with the sedimentary package that crosses the centre of the property. A major 060" diabase dike is interpreted to cross the northwest corner of the property. No major cross structures can be interpreted from the magnetic data.

A series of 2-5 Channel Input conductors crosses the central part of the claim group. They are primarily associated with finer grained sections of the metasedimentary package with a couple of anomalies being associated with the southern sedimentary contact. Two 3 Ch. conductors in the vicinity of lines 12-14W have been drill tested by Granges and the conductivity is caused by graphitic argillrtes containing up to 10^6 pyrite. The other conductors have an undetermined cause.

The EM trends defined by a helicopter EM and magnetic survey flown in the Halcrow project area are compiled on Figure 16 with the anomalies derived from the 1981 OGS survey. The helicopter survey was flown by Aerodat for Regal Petroleum and forms part of a larger survey. Attempts to locate the digital data for this survey have thus far


21

failed. The HEM flight line spacing was 100m compared to 200m for the INPUT survey. The flight line direction was north-south for both surveys. Reprocessing of the INPUT data has been carried out and is discussed in the 1993 Swayze report (Panagapko et. al., 1993).

The Aerodat interpretation maps were reviewed and the trends shown on Figure 16 represent the digitized EM trends, differentiated as moderate, weak and very weak, together wfth interpreted VLF axes and structural breaks. The overall trend direction of the EM data is northwest/southeast, corresponding to the strike of the geology. There is good agreement between the HEM and INPUT anomalies, though the Aerodat data has defined a more extensive system of weaker trends, presumably related to geological contacts and structural features. The 100m HEM data also provides more detail. In view of this the effort to locate the digital archive data should continue.

Three areas of potential interest are indicated. In the northwest increased conductivity and disruptions in the EM trends are associated with a major northeast trending diabase dike. Similarily, in the extreme southeast corner of the property, increased conductivity is noted, in this case, corresponding to north-south breaks, indicated from the regional magnetic data.

An interpretation of the airborne geophysical data from the OGS and Regal Petroleum surveys is given in Figure 16. A colour plot of the airborne geophysical data is shown in Figure 17.

9.0 Conclusions

As a result of work completed to date on the Halcrow property, the following general conclusions can be made:

1) The property is underlain by a series of mafic to intermediate volcanic flows and lesser pyroclastics that are in contact with a sequence of coarse to fine clastic metasediments. The volcanic rocks are of Mg-tholeiite and Fe-tholeiite chemical affinity and comprise both flows and occasional tuffs. The southwestern limit of the property is underlain by an ultramafic intrusive unit (dunite). The sedimentary rocks are difficult to classify as sediments due to the local intense regional strain which these rocks have been subjected to. Congolmerates contain a high percentage of volcanic fragments but occasionally contain rounded granitic clasts.

2) Bedrock exposure is very poor overall. On the eastern half of the property, where the majority of the rock is exposed, there is only about 1*fc outcrop. The remainder of the area is covered by extensive glaciolacustrine sand. The western half of the claim group is almost devoid of outcrop, due to extensive outwash and esker deposits.

3) The central part of the property has been subjected to high strain, with evidence of strain being extreme fissility in finer grained sediments and flattening of clasts in the coarser grained formations. Accompanying this high strain is more intense alteration. The primary alteration minerals are ankerite, sericite and silica, with most of the alteration being confined to the central sedimentary package.

4) Input anomalies are associated with the clastic sediments and, to a lesser extent, the massive volcanic units.

10.0 Recommendations

The next phase of exploration on the Halcrow property should consist of the following work:

1) Ground magnetic and VLF surveying of the new grid. This work should be completed late in 1994, after the lakes have frozen over, to allow for complete coverage.

2) IP/Resistivrty surveying of selected lines based on geological mapping, interpretation of airborne and ground geophysical data, and overburden considerations. This work should be completed during spring-summer 1995 to avoid winter problems.


23

3) Some prospecting or ground follow-up may be required as a result of the geophysical surveys undertaken. This may be limited by excessive overburden.

4) Diamond drill testing of selected geological and geophysical targets. Approximately 1200 metres of drilling is proposed and will be carried out in fall 1995.

This work is estimated to cost S9,000 for the geophysics in 1994 and S75,000 for the geophysics and drilling in 1995.
