Point Location Description: Pit on claim L.1606.

Location Method: Field Visit with GPS

Access Description: Access to the property is by gravel road at the Portelance property, 0.2 km north of the bridge in Kenogami. The road goes east for 0.9 km to the pipeline. The showing is .76 kilometres northwest along the pipeline and about 100 m to the west. The pipeline is passable by truck.

Exploration History

The original claim was staked by A. Gibson in 1911 and patented in 1915. The patent was forfeited in 1958. Prior to 1946 the pit was sunk. In 1939 and 1940, Sylvanite Gold Mines, Limited completed an extensive exploration program on the Tremblay Claim immediately to the south of the pit on the McCombe property. Large trenches in the overburden were excavated (totalling over 160 m in length) and extensively sampled. Two holes, totalling 152 m were diamond drilled. Veins trended at 330 degrees with assays to 2.76 ounce Au per ton. Assays were erratic. The original showing had ore grade values across 3 feet for a length of 25 feet. Assay results of the 2 drill holes were disappointing. In 1981, Norcana Resources Limited completed a VLF-EM and Magnetometer survey over thirteen claims. In 1983, Orcana Resources Limited mapped the property and completed a 34-hole overburden drill program totalling 70 m of drilling. In 1984, Orcana diamond drilled a 111 m drill hole and a 130 m diamond drill hole was completed in 1985. Best assay 0.016 opt Au over 1 foot. The diamond drill holes were put down to test showings to the northwest. In 1995 and 1996, the property was prospected, areas stripped and a beep mat survey was completed by B. McCombe. Geological mapping was completed by Kinross Gold Corporation in 1997.

Geology Comments

Dec 07, 2005 (D Guidon) - The rocks are mafic volcanic, probably Mg tholeiites. They vary from very coarse grained flows with gabbroic textures, to massive, to pillowed to porphyritic. Strike is generally 330 degrees. Minor carbonate and leucoxene alteration exists in the relatively fresh rocks. A quartz vein could be observed in the walls of the pit. It appeared to be approximaely 30 cm wide. The strike and dip are 270-70. Waste material around the pit is composed of altered tholeiitic basalt. The samples are chloritized, sericitized, pyritized, carbonatized and silified. Samples collected contained up to 5% fine grained pyrite. Assays were disappointing.

Lithology

Lithology Comments

Dec 07, 2005 (D Guidon) - Samples of broken tholeiitic basalt collected around the pit indicate that the rocks are altered with chlorite, sericite, carbonate, silica and pyrite. The carbonate is both calcite and Fe-dolomite as pervassive. The most intensely altered sample contains approximately 30% quatz and 5% fine grain pyrite disseminated along fractures.

Mineralization

Mineralization Comments

Dec 07, 2005 (D Guidon) - During the May 4, 1998, I thought I saw visible gold with pyrite in the vein just east of the shaft.

Alteration Comments

Dec 07, 2005 (D Guidon) - Fine- to coarse-grained, dark green to buff, chloritized, sericitized - cut by minor 2mm qv up to 30% qtz - 1-2% subhedral 1mm py - 1-2% calcite filling fractures - 5-10% high Fe-dolomite pervassive interstitial - sericitized - 10-15% - 5% clhorite - 5% .5mm anhedral py.

Date: Jun 25, 1997

Geologist: D Guidon

Notes: Property visit Aug 29, 1995 with B.McCombe. The pit is approximately 3 by 5 feet and surrounded by chicken wire wrapped arround surrounding trees. The vein is visible in the walls of the pit. The vein and structure within the pit stike 270 degrees and dip approximately 70 degrees north. Broken muck to the south of the pit is silicified, carbaonatized, chloritized, sericitized and pyritized. Assays of the samples collected are anomalous but low. McCombe reported samples with assays to almost 0.1 ounce Au per ton (personal communications). The vein is narrow but the width and stike length of the alteration have yet to be traced. The vein was sampled during a property visit by Kinross Gold Corporation in 1996. A sample from both sides of the shaft assayed2696 and 2745 ppb Au. The shaft is 3 x 5 feet and was measured to be 36 feet deep. The property was revisited May 4, 1998 with B.McCombe and D.Robinson. Since the first visit, the area around the shaft has been stripped and washed. It appears that the carbonate alteration is pinched out in the shaft area and widens to the south. At the shaft, the alteration zone is 10 m wide. It also appears to strenghten to the south. A stripped area, 5 x 15 m, is exposed approximately 65 m to the south east of the shaft at a bearing of 115 from the shaft. To the east of the shaft, the shaft vein is offset to the north by a fault striking at 355. The offset is small.
