Point Location Description: General
Location Method: Conversion from MDI
Access Description: The Pincher Lake Occurrences are located about 30km south of Dryden in northwest Ontario. Highway 502, a paved, all weather road connecting Dryden and Fort Frances crosses the northern part of the property. The original access road from Minnehaha Lake to Gold Rock lies on or near the western part of the claims. This road is now partly grown in but can be travelled on foot, by ATV or snowmobile. The present access road to Gold Rock crosses the southeast part of the claims. This road is not grown in but is not maintained. Travel on this road is possible with 4WD vehicles in dry weather or by snow machine in winter. (Assessment File 52F07NE BBB-3, J.W. Redden, 1989, Kenora Resident Geologist Office)
The area containing the claim block was first explored by prospectors during the 1890s. Work was carried out on a number of gold-bearing quartz veins in the area over the next few years. A few test pits and trenches are the only evidence of early work on the present claims. No documentation of this early work has been found. Sporadic exploration has been carried out ever since, however the work is poorly documented. No evidence of extensive work was found in the field. The only major exploration programme for which records exist was carried out by Asamera Inc. in 1983. Asamera, under a joint venture agreement with Shield Development Company Limited carried out a major exploration programme over a block of 97 claims. Most of the present claim block was covered by this programme. Work on the claims included line cutting, ground magnetic and VLF surveys, rock and humus geochemical surveys, and a geological survey. One day of stripping and 12 drill holes on 3 different quartz veins was also done. A number of interesting targets were located, however no additional work was done and the project abandoned. W. Sovereign prospected in the northern part of the block and discovered several areas of quartz veining. Assessment File 52F07NE BBB-3, J.W. Redden, 1989, Kenora Resident Geologist Office)

Geological Age: Precambrian
Feb 24, 2010 (C Ravnaas) - The geology underlying the claim block is shown on O.G.S . Map 2476 to consist principally of mafic volcanics with minor felsic volcanics and a few felsic dykes. Mapping by Asamera resulted in very little revision of the geology. Shearing and alteration is widespread throughout the claim block. Shear directions of northeast - southwest, north 70 degrees east - south 70 degrees west and east-west occur on the property. The northeast - southwest shearing follows the regional foliation. Carbonatization and silicification are associated with the shearing. Pyritization is present in this shear direction at the extreme south end of the property. Gold is associated with this shear direction. The east - west shearing and the north 70 degrees east south 70 degrees west shearing may represent a single shear event. These shears are very poorly exposed on the property.

Feb 24, 2010 (C Ravnaas) - Assays: 9106 and 1393 ppb Au. All known gold occurrences in the area are associated with silicification. Carbonatization is widespread and is often present over large areas not known to contain much more than slightly anomalous gold values. Pyritization is considered as a favourable indicator for gold. Often the pyrite is concentrated in the wall rock, with the quartz vein containing gold to be rather low in pyrite. Chalcopyrite in a quartz vein appears to be a favourable indicator of gold.
