Summary and Conclusions

During July 2004, geological mapping, thin section collection and a total of 6 whole rock lithogeochemical samples and 12 soil samples were collected and analyzed over the claim KRL 1184170, located on the McKenzie Island, Dome Township Property. The purpose of the work was to follow the anomalous gold and trace-element values, received after the previous phase of work on the claim (Year 2002, W0220.01282) and increase the knowledge of the petrology and identify the vectoring of alteration and mineralization. Mapping of the lithology of the area shows presence of felsic to intermediate flows and tuffs. Quartz veins, up to 20 cm in thickness, containing pyrite, arsenopyrite and chalcopyrite, hosted in the silicified intermediate to felsic volcanic rocks, were sampled.

In conclusion, the 2004 mapping and sampling enhanced the understanding of the geology, rock type and alteration identification and lithogeochemical sampling became a basis of multi-element analysis to compare the property with the known deposits in the region. Analysis of the B-horizon soil sampling results will increase understanding of the multi-element zonation on the property. Anomalous gold and trace-elements value suggest potential of the area.

Introduction

The claim KRL 1184170 (McKenzie Island) is located in the northern part of the McKenzie Island, Dome Township, Kenora-Red Lake Mining Division (Figure 1). During July of 2004, an exploration program, consisting of geological traversing, mapping, soil sampling, thin-section collection and lithogeochemical sampling and analysis was conducted on claim KRL 1184170. The mapping was focused on the area where previous work returned anomalous gold and trace-element values around the historic trenches. Soil sampling was performed across the claim group to estimate the multi-element zonation.

Property

The claim KRL 1184170 is composed of two 16-hectare claim units in Dome Township, Red Lake Mining Division. Originally it was recorded by PDC on August 8, 1994.

Location and Access

The property is located on the west side of McKenzie Island, Dome Township, Ontario, between latitudes 51 004'10" and 51 004'28" and longitudes 93 0 51"12" and 93 051'32", NTS 52 N/4. Depending on the season, access can be made either via boat or snow machine to the west shore of the island followed by a 100m traverse to the northern

boundary of the claim (Fig. 1). Access can also be made via numerous cross-country ski trails that cut through the property.

Previous Work

The first recorded work in the area was done by South McKenzie Island Mines Limited and consisted of a programme of stripping, trenching and diamond drilling (5 holes totaling 185m). No work was recorded on the property until 1980 when Gold Fields Resources Ltd. staked the area and performed a programme of geological mapping, magnetometer and V.L.F. surveys in 1981 (Cameron, 1981; Boniwell, 1981; Chute, 1982), as well as detailed I.P. surveys, a geochemical humus sampling survey in 1982 (Seara, 1983; Bald and Cameron, 1983) and power stripping in 1983 (Cameron, 1983).

In August 1986, Dighemlll airborne magnetic and electromagnetic surveys were carried out over the property by Noramco Explorations Inc. (Smith, 1986). Pure Gold Resources Ltd. conducted geological fieldwork in the area during the fall of 1986 (Rusk, 1986). Their work examined the known showing in the east-central part of the property and enlarged upon the known associated zone of silicification.

During February 1987, Noramco Explorations, Inc., the operator for Pure Gold Resources Ltd., conducted 388.8m of diamond drilling on the property (Donaldson, 1987). The highest Au values were reported from a felsic tuff unit (600 ppb Au).

Placer Dome performed limited exploration on the property in 1999 and 2002. Soil geochemistry was performed in 1999. Elevated values were recorded for gold, silver, and arsenic. Rock sampling and MMI sample line was done in 2002, which confirmed the anomaly.

General Geology

The property lies within the east-west trending Red Lake greenstone belt of the Uchi Subprovince of the Archean Superior Province of the Canadian Shield. In the Red Lake area, the belt consists mainly of volcanic rocks with lesser amounts of clastic sedimentary rocks and is bounded on all sides by large granitic batholiths.

Property Geology

The property is underlain by felsic metavolcanics (tuff, crystal tuff and agglomerate), minor intermediate to felsic metavolcanics (tuff and flow). Alteration is presented by intense silicification and minor carbonization. Bedding is oriented northeast (NE) to southeast (SE) and is steeply dipping variably to the north and south. Quartz veining in the stripped and trenched area is orientated at 0600 and ranges from a few centimeters to 20 centimeters in width.

Mineralization

Finely disseminated pyrite is present in numerous outcrops throughout the property. In the stripped and trenched area, disseminated pyrite and arsenopyrite occurs in the felsic tuff, and pyrite, arsenopyrite and chalcopyrite are associated with the quartz veining. Anomalous gold values were historically defined in the quartz vein as well as the silicified zone associated with the quartz veining.

Structure

The rocks outcropping on the property are relatively un-deformed with the exception of the stripped and trenched areas. Bedding in the felsic volcanics varies from 022 0 to 085 0 azimuth dipping northwest at 480 to 900 . Near the stripped and trenched areas, the rocks begin to display deformation with the development of foliation, which varies from 045 0 to 0900 azimuth, dipping steeply northwest to vertical. The mapped shear zone (Fig. 5) has a strike 200 deg, and dip 65 deg, NW. Cleavage has a strike 335 deg, dip 45 deg, NE.

Mapping, Thin-section Collection and whole rock lithogeochemical Sampling.

Previous sampling performed by Placer Dome (CLA) Ltd, Campbell Mine in 2002, returned elevated values for gold in two samples: BO7159 - 159.0 ppb and BO7160 - 421 ppb, with anomalous arsenic values - 445 ppm and 15 ppm respectively. Additional sampling of this area was done in purpose to confirm the anomalous values and estimate the lithogeochemical multi-element features, which can be an indicator of deep mineralization.

Six samples, described in the Table I., were collected from the area. Analytical results are presented in the Appendix 3. Four thin sections were collected around and from the silicified shear zone (Fig. 2). The petrographic study will show the alteration styles and will set the correlation with a multi-geochemical analysis.

Soil Sampling

Soil sampling was performed across the property in order to estimate the multi-element zonation, reflected on the B-horizon soils, on the northern part of the area, which was never sampled historically. The collected material was presented by brown soils, brown clay and sandy clay from the well-developed B-horizon. Sampling was done using the auger; coordinates were taken using GPS. Samples were submitted to the ALS Chemex laboratory in Vancouver. The description of the samples and their coordinates are presented in Table 2. Analytical results are presented in the Appendix 4.

Recommendations

Based on the 2004 work, it is recommended to analyze the multi-element distribution in order to assess the alteration halos and identify the possibility of deep meneralization, which does not have a surface expression. Comparison with the petrographic study will establish the correlation of the geochemistry and mineralogy.

INTRODUCTION

This report presents the petrography of six samples from McKenzie Island in the Red Lake Greenstone Belt and interprets the results with respect to lithology, alteration, metamorphic conditions, and deformation. Digital versions of the report, sample scans, and photomicrographs are included on the compact disc in the back pocket. To maximize objectivity, study was done without access to detailed locations or previous company reports.

GEOLOGICAL SETTING

After Horwood (1940), McKenzie Island is underlain mainly by metasedimentary rocks intruded by the Dome and McKenzie granitic plutons. Mafic metavolcanic rocks are limited to the northernmost tip of the island and several lenses within the Dome pluton at the south end. Andrews et al. (1986) remapped the metasedimentary rocks as felsic metavolcanic rocks that formed part of a "Calc-alkaline Sequence". More recently. Parker (2000) and Sanborn-Barrie et al. (2001) subdivided the latter lithologic package into felsic metavolcanic rocks of the McNeely sequence (Confederation assemblage, -2.75-2.73 Ga) and metamorphosed volcanoclastic/clastic rocks and iron formation of the Bruce Channel assemblage (-2.89 Ga). McKenzie Island falls within Parker s (2000) distal carbonate alteration zone. On structural maps of the Red Lake Belt (Andrews et al., 1986; Sanborn-Barrie et al., 2001), McKenzie Island appears to be a zone of relatively low strain bounded by high strain zones lo the northwest and northeast. Southwest- northeast D2 structural trends southwest of the island and east-west to northwest-southeast trends east of the island (Sanborn-Barrie et al., 2001) are not continuous across the island. Except for the northeast corner that is located in the upper greenstone zone of regional metamorphism (Thompson, 2003), most of the island is presumed to be in the lower greenstone zone. The thin sections used in the regional study, however, were limited to the northeast corner. In the context provided by the belt-scale metamorphic map, the available data are consistent with peak metamorphic temperatures (375-425 0 C) and pressures (~ 3 kbars) in the middle greenschist facies. The metamorphic study concluded that the McKenzie and Dome plutons intruded early in the compressive stage of the orogenic process before regional metamorphic conditions reached a maximum, and are, therefore, themselves metamorphosed. More petrographic data from McKenzie Island will provide critical constraints on the metamorphic hot spot that appears to be associated with the past-producing Cochenour-Willins gold mine (Thompson, 2003).

PETROGRAPHY

Of the six samples (Figure 1) examined here, four are from one locality (rlmi-A,B,C,D) and two are assumed to be from another (rlmi-31201, rlmi-31206). All six samples are felsic metavolcaniclastic rocks (see Table l for mineral assemblages). Photomicrographs from different parts of each thin section are presented with both plane polarized light and crossed nicols. Image numbers in the figures refer to the photomicrographs included on the CD in the back pocket. For maximum resolution of photomicrographs, view individual images on the CD in a full screen format.

Sample rlmi-A (felsic litho/crystal metatuff)

Pale grey to beige weathering, this sample appears to be relatively homogeneous and massive in hand specimen. In thin section, there is a weak to moderate preferred orientation defined by the long dimensions of mineral and lithic clasts and by aggregates of white mica (Figures 2, 3). The chlorite-carbonate filling in between a pulled apart quartz grain (Figure 3ab, centre-right) is further evidence of syn-metamorphic strain. Rounded to subangular grains of plagioclase (0.5-1.5 mm) are variably altered to very fine-grained white mica ^0.005-0.02 mm) along grain boundaries and internal fractures. In some cases, only a small part of the plagioclase grain has survived (e.g., left and below pulled-apart quartz grain, Figure 3ab). Quartz occurs as well rounded to angular grains (0.1-2.0 mm). Many have the scalloped edges and indentations caused by partial resorption during the magmatic history of the rock (Figure 2de). While some quartz grains appear to be unstrained, others are divided into deformation domains by thin polygonized zones (Figure 2c, left centre, Figure 2d, lower left). Thin angular grains look like fragments that could have formed during explosive volcanic activity (Figure 3ef, lower left). Well-rounded mafic lithic clasts (0.5-1.0 mm) rich in chlorite and opaque minerals are also present (Figure 3cd). Although many of the very fine-grained aggregates of white mica are derived from igneous plagioclase, other irregular to wispy-shaped examples may be recrystallized volcanic glass (Figure 2de, upper left; Figure 3ef). Distinguishing the very fine grained white mica-quartz-feldspar-opaque mineral matrix from clasts is not straightforward. Carbonate is rare (the sample does not fizz in reaction to dilute HC1). Small opaque mineral grains (mostly "^0.02 mm) and chlorite are concentrated in mafic lithic clasts, but do occur in the matrix. The wide range in grain size from 0.005 to 2 mm, metamorphic mineral assemblages, relict igneous grains of quartz and plagioclase, variable clast type, and poorly-sorted aspect are the basis for calling this sample a felsic lithic/crystal metatuff.

Sample rlmi-B (felsic lithic/crystal metatuff)

This massive to weakly foliated rock has a rough pale grey to white weathered surface. Localized recessive zones suggest the presence of carbonate. Millimetre-scale quartz grains glisten on the fresh surface. Deformation is more heterogeneous than in the previous sample with most of the strain concentrated in sub-millimetre chlorite-rich seams (Figure 4de) or millimetre-scale white mica-rich zones (Figure 5cd). Carbonate veins with narrow chlorite-rich rims (Figures 4de, Sab) appear to predate the narrow chlorite deformation zones. White mica alteration of rounded to blocky plagioclase grains (0.25 to l mm) is more pervasive (Figure 4ab, upper right) than in sample rlmi-A. Quartz (0.25 to l .75 mm) occurs as angular to well rounded grains that show variable degrees of strain (compare Figures 4, 5). Prominent relatively homogeneous patches of very fine-grained material (pink and grey under crossed nicols) may be fine-grained felsic lithic clasts. Rounded to irregularly-shaped aggregates rich in opaque minerals and chlorite (Figure Sab) are interpreted to be mafic lithic clasts. Chlorite also replaces plagioclase grains and occurs in seams that cut across the sample. Aggregates of very fine- grained white mica that can be interpreted as metamorphosed volcanic glass are rare. Tiny opaque grains ^0.02 mm) occur in chlorite aggregates and in the matrix. Carbonate is present in veins (fizzes in dilute HC1) and in much smaller pull-apart features. Once again, wide ranging grain size, metamorphic minerals, relict igneous grains of quartz and plagioclase, variable clast type, and poorly-sorted aspect are the basis for calling this sample a felsic lithic/crystal metatuff.

Sample rlmi-C (felsic quartzofeldspathic phyllite)

Pale beige to white weathering and friable, this felsic rock (Figure 6) reveals a well- developed preferred orientation of very fine-grained white mica (*:0.005 to 0.01 mm) in thin section. Sub-millimetre quartz-carbonate veins, oblique to the mica fabric are folded and weakly boudinaged (Figure 7ab). Quartz and feldspar (O.01 mm) are subordinate to white mica outside the veins. The former occurs also as scattered grains that are coarser than white mica (Figure 7a, upper centre). Bluish-green to pale green tourmaline (0.02-0.04 mm) is a significant minor phase in the rock. Scattered throughout (Figure 7ef), locally it appears to have grown across the mica fabric (Figure 7cd). In some cases, tiny prismatic grains overgrow a rounded nucleus. Trace amounts of chlorite are present in the matrix and in the polygonized quartz- carbonate veins. Carbonate is located in pull-aparts formed by boudinage of the veins. Apatite is a prominent trace mineral. Much more homogeneous with respect to grain size and mineralogy, lacking the meta-volcanoclastic texture of samples rlrni-A and rlmi-B, and more penetratively deformed, this rock is interpreted to be a very-fine-grained felsic metatuff or a metamorphosed altered rhyolite flow.

much finer-grained zones (Figure 8bc, lower left; Figure 9ab) characterized by tiny angular grains of quartz (0.05-0.7 mm). In both cases, a preferred orientation of mineral grains and clasts is present. Euhedral plagioclase (Figure 8bc) and partly resorbed quartz (Figure 9ef) similar are evidence of the ultimately igneous source of this rock. The white mica aggregates interpreted to be derived from shards of volcanic glass (Figures 8de, 9cd) support a volcaniclastic origin as well. Clusters (Figure 8b-d) and aggregates/seams (Figure 9a-f) of euhedral epidote (0.1 mm) with chlorite are a distinctive feature. They may represent concentrations of carbonate and chlorite that reacted to form epidote with increasing metamorphic grade consuming all the carbonate. Opaque minerals occur as individual grains and as clusters associated with what may be "fuzzy" titanite. An unknown mineral may be another epidote group phase or a variety of titanite. Trace amounts apatite and of prismatic tourmaline (0.15 mm) are present. Wide range of grain size, presence of igneous plagioclase and quartz crystals, possible metamorphosed glass shards, and poor degree of sorting are consistent with this sample being a bedded felsic metatuff or felsic meta-epiclastite.

Sample rlmi-31201 (felsic metatuff)

The homogeneous and massive-looking chip of rock (Figure 10) that was thin-sectioned has a pale-grey to beige weathered surface. Distinguished from the other five samples by a much lower content of very fine-grained matrix (Figure 11 a-f), the resulting closely-packed appearance of mineral and lithic clasts is the result. Clasts and matrix outline a weak preferred orientation. Rounded to blocky plagioclase, replaced to varying degrees by very fine-grained white mica, predominates over subrounded grains of quartz (Figure 11). Chlorite-opaque mineral aggregates

Are smaller here (Figure l led). The chlorite rims on carbonate veins (Figure l led) are more sharply defined in this rock than they are in sample rlmi-B. The veins react strongly to dilute hydrochloric acid. Carbonate is also present in the matrix and as a replacement for plagioclase. Rounded to irregular grains of opaque minerals are typically less than 0.04 mm across. There are trace amounts of apatite. Where present, the matrix is a very fine-grained aggregate of white mica, quartz, and feldspar. With its somewhat higher degree of sorting and higher clast to matrix ratio, this rock is another variation on the theme of metamorphosed felsic volcaniclastic rocks that is represented by the other five samples.

Sample rlmi-31206 (felsic mctatuff)

Pale grey to white weathering, this rock exhibits a weak foliation and some variation in grain size that may represent bedding or the intercalation of lenses of relatively coarse and fine material (Figure 12). In thin section, the long dimension of white-mica aggregates (Figure 13a- d) defines a weak preferred orientation that parallels a crude alignment of other mineral grains and aggregates. Overall, the replacement of angular grains of plagioclase (0.5-1.5 mm) by white mica(O.01 mm) is quite advanced (Figure 13a-t)- Quartz grains (Figure 13ab) tend to occur as either angular fragments (~0. l mm) or rounded, p art l y-resorbed grains (0.7-1.5 mm). Individual grains or aggregates of euhedral epidote (0.07-0.1 mm) are quite common but chlorite and carbonate are still present in the matrix with and without epidote. Only half of the distinctive aggregate of very fine-grained white mica (Figure 13cd) is included in Figure 13cd. As is the case with other samples in the study suite, matrix ^0.02 mm) is composed of white mica, quartz and probably feldspar (too fine-grained to be certain). The mixture of lithic and crystal clasts, the poorly sorted aspect, relict igneous and quartz grains, metamorphic assemblages, and texture are the basis for designating this rock a metamorphosed felsic volcaniclastic.

INTERPRETATION

Lithology

The mineralogical and textural features of the six samples are consistent with an origin as felsic crystal/lithic tuffs. The overall grain size range less than 2 mm may indicate a significant distance from the felsic volcanic centre. If the samples exhibiting a degree of compositional layering (rlmi-D, rlmi-31206) have been subjected to some degree of reworking by water, the term epiclastite would be more accurate. The absence of lithic clasts, the very fine grain size, higher white mica content, tourmaline, and generally more homogeneous aspect distinguish sample rlmi-C. It is important to determine if this sample is characteristic of a lithologic unit that is concordant with stratigraphy or of a discordant zone of intense alteration and deformation. The presence of tourmaline can be explained by exhalative processes accompanying deposition of very fine-grained volcaniclastic rocks or by synvolcanic hydrothermal alteration after deposition.

Deformation

The variable, but mainly weakly developed preferred orientation of minerals and mineral aggregates, the fractured plagioclase, and the polygonized quartz grains are evidence that these samples have been involved in the ductile deformation history of the Red Lake Greenstone Belt. Assuming that the preferred orientation observed in thin section is equivalent to D2 structures elsewhere in the belt, the absence of structural trends across the island suggests either that the structures observed in thin section are not measurable at outcrop scale or the structural mapping is incomplete. The low grade of regional metamorphism that accompanied the formation of deformation fabrics and the resulting fine-grain size of metamorphic minerals that define the structures may also part of the problem.

As discussed above, whether or not the most intensely deformed sample (rlmi-C) is part of a particular lithologic unit or a deformation/alteration zone is an important question to be answered by further work.

Metamorphism

The pervasive metamorphic textures and the coexistence of chlorite and white mica (Table 1) in all six samples indicate that the grade of regional metamorphism is in the lower greenstone zone. The implied temperatures of 350-4000 C and pressures less than 4 kb are typical of the lower greenschist facies. Although the location of the samples on McKenzie Island is not known to the author of this report, the new data support the extrapolation of the lower greenstone zone across the southern two thirds of the island (Thompson, 2003). Moreover, it appears that these rocks were not affected by the upper greenstone to amphibolite zone metamorphic "hot spot" that is associated with the Cochenour-Willins past-producing gold mine. On the other hand, the location of the epidote-bearing samples (rlmi-D, rlmi-31206) relative to the other samples and to this relatively high metamorphic grade zone is important. A metamorphic reaction between carbonate, white mica, and chlorite to produce epidote could occur within the lower greenschist facies as a result of higher temperatures and/or a change in

metamorphic fluid composition. That is, if the presence of epidote in these samples and its absence from the other four can be attributed to increase in temperature and/or change of fluid composition, the change may be significant with respect to gold mineralization.

Alteration

Is the remarkably pervasive, but partial to complete, replacement of plagioclase by white mica a product of hydrothermal alteration associated with volcanism or is the alteration a product of processes related to regional metamorphism? Clearly, the white mica present in the rocks now is a metamorphic mineral that grew or, at least, recrystallized during metamorphism and deformation of the rocks. During metamorphism, detrital or igneous plagioclase and potassium feldspar commonly change composition and texture without being replaced by white mica. The replacement of plagioclase by white mica, therefore, likely requires interaction with a hydrous fluid phase sufficiently rich in K+ and or Na4- ions that feldspars become unstable with respect to K-mica ("sericitization") or Na-mica ("paragonitization"), respectively. If the process occurred during or soon after volcanism, on or near the sea floor, potassic or sodic clay minerals could form. Subsequent metamorphism and deformation would recrystallize and re-orient the synvolcanic hydrothermal micas or form new ones with a preferred orientation from the clay minerals. Alternatively, the feldspars in tuffaceous rocks remain unaltered until potassic hydrothermal fluids derived from metamorphism of rocks deeper in the crust transform the igneous feldspars into white mica. Both scenarios have potential to be prospective for gold mineralization. Gold ore associated with synvolcanic, pre-metamorphic hydrothermal alteration, however, should show evidence of subsequent metamorphism and deformation. Syn- metamorphic ore should cut across one or more generations of structures and perhaps be associated with textural evidence that it is synchronous or younger than the predominant metamorphic assemblages.

Carbonate-chlorite veins present in samples rlmi-B and rlmi-31201 are evidence of another possible alteration event. This may be the style of Parker's (2000) distal carbonate alteration zone. Less pervasive than white mica alteration of plagioclase, these features appear more likely to be part of the main metamorphic and ductile deformation events rather then definitively older or younger than these events. On the other hand, epidote-rich seams in sample rlmi-D can be interpreted as metamorphosed carbonate-chlorite veinlets.

A key aspect of both these potential hydrothermal alteration events yet to be examined is whether or not the intensity of the transformation of plagioclase or of the density of carbonate- chlorite veinlets increases toward know gold mineralization. Such a relationship could provide a vector that, integrated with other data sets, enhances exploration of known gold deposits and helps to define new targets.

CONCLUSIONS

* All six samples represent variations within a single package of metamorphosed felsic volcanic rocks that is dominated by crystal/lithic metatuffs.

* Synmetamorphic ductile deformation has modified to varying degrees the sample suite.

Peter H. Thompson Geological Consulting Ltd. McKenzie Island Project l g

* Regional metamorphic grade of the felsic metavolcanic sequence attained maxium temperatures (350-4000 C) and pressures (3-4 kbars) in the lower greenschist facies.

* The suite of samples falls outside the thermal and/or fluid composition effects related to formation of the metamorphic "hot spot" that is associated with the Cochenour gold mine.

* If the intensity of either or both the more pervasive white mica alteration of plagioclase and the more restricted carbonate-chlorite vein type alteration can be linked to gold mineralization these features could provide a useful tool for gold exploration.

RECOMMENDATIONS

* Determine if the white mica-rich, intensely foliated sample (rlmi-C) is part of a concordant stratigraphic unit or of a discordant deformation/alteration zone.

* Confirm with more extensive sampling on McKenzie Island whether or not the high metamorphic grade anomaly associated with the Cochenour-Willans past producing gold mine extends westward across Bruce Channel and whether or not it can be linked to gold mineralization on the island.

* Explore the degree to which white mica alteration, carbonate-chlorite alteration and the origin of sample rlmi-C can be used as vectors for gold exploration.
