Geology Comments

May 06, 2008 (D Guidon) - from AFRI 42A01NE2003 The property is underlain by Keewatin (Lower Blake River) tholeiitic metavolcanics of intermediate to mafic composition. These consist of massive flows, pillowed flows and occasional interflow breccias. A large body of quartz-feldspar porphyry of indeterminate age traverses the approximate middle of the property in a N/E-S/W direction with an average thickness of several hundred feet. This rock anastomoses or swarms near the southern boundary of the property. All of these rooks are metamorphosed from lower to middle greenschist facies. Associated with the body or bodies of porphyry are parallel or sub-parallel fault or shear structures especially evidenced at the volcanic porphyry contact zones. In a few locations, these faults tend to display only minor ductile shear and appear to be mainly dilatant breccias; however, in the main area of intensive exploration, strong ductile shearing is at least spatially associated with these contacts. The property lies on the nose of a west plunging east-west trending syncline and much of the rock has undergone very little strain. However, a shear zone was revealed in the recent drill program within the workings of the No.l shaft. This fault trending at 078 degrees is believed to roughly parallel the trend of the major gold-bearing structures in Kirkland Lake, but the feature dips steeply to the north. The main Kirkland Lake gold deposits occur within Temiskaming Group rocks higher in the stratigraphic section.

Lithology

Lithology Comments

May 06, 2008 (D Guidon) - Zone A is underlain by massive to pillowed iron and magnesium tholeiites. These rocks are separated by a north dipping shear zone with shearing trending at 078 0 (however, a siliceous sedimentary-tectonic breccia unit is also present on this contact in some sections- inferring a south facing top to the iron tholeiite). Many narrow faults defined by fault gouge and confined shear zones were intersected in the drilling and are inferred to trend at approximately 025 Q and dip 60 0 S. The trend of the shear zone in the area of drilling is apparently 100 0 possibly due to displacement of the shear along these crosscutting faults. More detailed examination is required to resolve the possible relationships between these faults and the distribution of commercial grade gold mineralization. A series of anastomosing quartz feldspar porphyry dikes believed to trend at approximately 063 0 and dip 75 0 N are also spatially associated with the gold mineralization in Zone A. Gold occurs both in quartz carbonate veins in the shear zone and in volcaniclastic and sedimentary breccias. The mineralization is spatially associated with the inferred top of the iron tholeiite unit within an east-west trending north dipping but south facing sequence of iron and magnesium tholeiites. The shear is sub-parallel in strike to the volcanic sequence but with a slightly gentler dip traverses the volcanic flows. For the purpose of map control the volcanic rocks in Zone A are subdivided on the basis of colour index and certain distinctive characteristics into: Iron Tholeiite: buff to dark greenish grey with a red to lavender tinge; fine grain to aphanitic massive flows frequently with pervasive cooling fractures, zones with pillows and pillow breccias and hyaloclasis trending into multiple flow units with pillows and pillow breccias with hyaloclastic and partially sedimentary breccias. Magnesium Tholeiite: (Leucoxene Rich) Buff to medium greenish grey rock with buff to lavender speckles and blotches of leucoxene to 20%; generally fine to coarse grain, thick flow with lesser pillowed flows but some thinner units may be sills. Magnesium Tholeiite: (Leucoxene Poor) Buff to medium greenish grey rock generally fine grain with very fine grain leucoxene in rare cases; flows and pillowed flows. Magnesium Tholeiite: (Amygdaloidal, fractured, box work calcite) Light to dark greenish grey aphanitic to fine grain rock often with outstanding quench, chill and degassing textures; amygdules with sulphide, calcite, and/or chlorite filling up to 20% of rock; spherules to 30% especially at pillow tops and rims; wedge shaped and cris-crossed or box-work healed fractures containing calcite comprises up to 20% of rock; the unit comprises more massive rather than pillowed flows and is less amygdaloidal in Hole GF90-15 which is furthest to the east.

Mineralization

Mineralization Comments

May 06, 2008 (D Guidon) - from AFRI 42A01NE2003 Quartz-carbonate and quartz-calcite veins occurring in zones of weakness such as shears, strained contacts and other permeable structures (eg.flow top breccias, sedimentary-tectonic breccias and hyaloclastites) are all potentially permissive to economic grades of gold mineralization on the property. Associated mineralization in gold-bearing zones consists of lenticular stringers of quartz, carbonate, calcite, pyrite, specularite, minor chalcopyrite, molybdenite, and graphite. Tellurides have also been reported. Alteration assemblages occur around all gold-bearing zones, but the alteration varies in different occurrences. Silicification is the most closely associated alteration or replacement in gold-rich zones. Carbonates, sericite, and epidote are also prominently associated. However, Zone A-4 is typified by the absence of silicification and veining and the presence of very subtle hematite-graphite addition with modest amounts of pyrite and chalcopyrite mineralization. Chlorite and epidote alteration are also distinctive features of Zone A-4. The gold-bearing zones are spatially associated with sheared and altered porphyries and metavolcanics which occupy a small zone extending over 4,000 feet of strike northeast-southwest through the property. This zone may be an extension of the Lakeshore Fault which is further to the southwest in Teck Township. On the Goodfish property it reaches widths of 1,000 feet. For purposes of discussion, the intensively explored areas of the property Fig. 4 may be referred to as Zones A, B, and C. The three zones comprise approximately 6 per cent of the property. Moreover, the bulk of recent work is confined to 2 per cent of the property. In Zone A the No.l shaft was sunk to 620 feet with more that 5,000 feet of lateral development carried out on four levels. The best gold mineralization occurred on the 300-foot level with a 3-foot width grading 0.50 oz gold per ton. However, this mineralization was insufficiently supported on adjacent levels. Most recent exploration, however, has been conducted in Zone A. Exploration in August to October 1990 and again in 1992 was directed to follow an intersection of 0.495/41.5' in hole GF90-4. Holes GF90-8 to GF90-15 and GF92-16 to GF92-19 comprising 7161 feet have tested four distinct gold occurrences - Zones Al, A2, A3 and A4. Zone A-l: The zone occurs on or near the stratigraphic top of the iron tholeiite unit and is characterized as a laminated iron enriched siliceous rock. Zone A-2 is a dark bluish grey molybdenum-chlorite-graphite-tourmaline bearing quartz breccia vein or veins within but not parallel to the main shear. Hole GF 90-4 intersected a 2.O foot vein with coarse visible gold which returned an assay of 5.08 ounces Au/ton. Zone A-3 occurs in the flow top of the amygdaloidal box-work calcite flow which comprises minor quartz carbonate veining with up to 1% molybdenite and 5-10% fine grain pyrite. This mineralization appears to correlate with reported high grade mineralization on the 450 foot level of the workings in the number l shaft. Zone A-4 occurs within a broader 10 to 30 foot zone which is a very dark greenish mauve grey iron tholeiite. The broad zone is highly altered with chlorite and hematite, intensively fractured (cooling fractures which have all, healed) and contains 1-15% secondary sulfides comprising pyrite and chalcopyrite. The gold enriched portion is visually indistinguishable from the rest of the zone at this time although it appears to have a much stronger magnetic attraction and a low sulfide content.
