Exploration History

1934: Claims staked and surface exploration carried out. 1935: Geological survey conducted, surface exploration continued, and a diamond-drilling program began in November. 1936: Exploration con't, including trenching and stripping. Diamond-drilling totalled 1,371.6 m. Three compartment vertical shaft sunk to 22.9 m; buildings cons't. 1937: Shaft sinking con't, and levels established. Five ton sample sent to the Hard Rock Mill. 1939: Surface exploration resumed; 1,990.3 m of diamond-drilling completed. Despite some spectacular intersections, operations were suspended and the option dropped by Howie Gold Mines Ltd. 1946: Shaft dewatered and underground operations resumed. Ore shipped to Hard Rock Mine's mill for treatment. 1947: Mining con't; operations suspended in Oct. due to lack of finances. 1958: Gulch Mines dewatered and drilled. No ore found and operations suspended. Shaft sealed. 1979: Airborne geophysical survey conducted by Gulch Resources. 1984: Property re-evaluated by Camel Oil and Gas Ltd. Claims were still held by Camel as of 1986.

Geology Comments

Dec 07, 2005 (B Nelson) - The Hutchison Lake geology consists of a metasedimentary belt trending ENE, bordered to the north and south by belts of mafic to intermediate metavolcanics. Further to the north, the bedrock is of granitic composition. Metasediments and metavolcanics are intruded by diorite, felsic porphyries, and olivine and quartz diabase dykes. The rocks have been subjected to regional shearing, which strikes in the neighbourhood of N80 degrees E. Regional folding has upturned the rocks to a steep or vertical position, and minor local folds are present. These features are best shown in the bedded tuffs. The shearing and minor folding of the rocks are believed to have been the dominant control in the localization of veins. In the underground workings, the higher grade material has been found to occur at the crests of folds and where the shearing is more pronounced. Post-ore faulting was noted by Morrow (1949) to be a common feature, but faults are of small magnitude and did not complicate mining operations. The ore bodies consist of highly irregular, branching, mineralized quartz veins in sheared and carbonatized tuffs and dacites (altered andesite). Quartz is the dominant vein material, but in some places sulphide mineralization is heavy. The carbonate and ankerite is very common in the veins, and along the wall rocks have been extensively carbonatized.

Lithology

Lithology Comments

Dec 07, 2005 (B Nelson) - The lavas consist of dark-green, moderately sheared andesites and pillow lavas and grey-green, massive andesites. They are highly altered and consist dominantly of chlorite, altered feldspar and calcite. A coarse grained basic rock occurs in several places on the claims. The rock may be a diorite or gabbro, but is considered to be a coarse-grained basic lava. Coarse agglomeratic fragmental material is also present in the western claims of the property. Bedded sedimentary tuffs are interbanded with the lavas in some places. They are typically more highly sheared than the lavas and are medium-grained to slaty in character. The coarser-grained ones consist mainly of feldspar. Many of them are high in carbonate and weather to a rusty brown color. Some contain disseminated pyrite. It should be noted that the structural information is fragmentary due to the massive nature of most of the lavas and the scarcity of outcrop.

Mineralization

Mineralization Comments

Dec 07, 2005 (B Nelson) - Gold occurs in some specimens as coarse, easily visible blebs and has been observed in the following associations: 1). In quartz gangue that is free from any visible fractures; or in fractures in quartz gangue, either with galena or alone. 2). In pyrite, sphalerite and galena as blebs and veinlets. 3). Along contacts between sphalerite and quartz and penetrating the sphalerite. A number of significant sample values have been obtained. Values reported by The Globe and Mail (July 6, 1937) ranged from 2.0 to 20.0 oz/ton Au over a vein width of 0.91 m. Diamond-drilling by Maylac Gold Mines Ltd. intersected values up to 11.6 oz/ton over a width of 0.41 m. 1959 diamond-drilling by Gulch Resources intersected only low gold values, the best of which was 0.03 oz/ton Au.
