Exploration History

1960: Diamond drilling by Castlebar Silver & Cobalt Mines in the area between Lang Lake and Saddle Lake. 1968-1972: Bochawna Copper Mines Ltd. and the Hanna Mining Company conducted an extensive exploration program in the area north of Lang Lake, including a diamond drilling program that outlined a copper deposit. 1969-1971: The Algoma Steel Corporation Ltd. conducted extensive diamond drilling and geophysics in northwest of Lang Lake for iron ore. 1969-1970: Card Lake Copper Mines Limited conducted grid mapping geophysics and diamond drilling for gold and base metals in the Saddle Lake, Boyes Lake, Card-Cannon Lakes, and Heinz Lake areas. 1970: Mextor Mineral Ltd. and Kennco Exploration Limited conducted geophysics and diamond drilling for base metals in the Saddle Lake area. 1984-1986: Duration Mines conducted geophysics, grid mapping and diamond drilling on the southern arm of the Lang Lake greenstone belt for base metals mineralization. 1985-1986: Geological, geochemical and geophysical surveys in the western Lang Lake area by Utah Mines. 1991-1992: Noranda Exploration Company Limited conducted grid mapping, geophysics and diamond drilling for base metals in the Lang Lake and Saddle Lake areas. 2003-2007: East-West Resource Corporation conducted geological and geophysical surveys and diamond drilling of the Lang Lake copper deposit.

Mineralization Comments

Mar 30, 2007 (Mark Puumala) - This occurrence is found within a quartz vein hosted within intermediate tuff (Weidner 1987). The rocks in the immediate area of the occurrence are indicated to be dominated by intercalated mafic to intermediate metavolcanic flows and tuffs. These metavolcanics are intruded by a relatively narrow (< 3m wide) anorthosite. Foliation in the area of this occurrence is oriented approximately 110/90 (Weidner 1987). The metavolcanic/anorthosite contact is also oriented 110/90. The metavolcanics are indicated to be moderately carbonate altered, with intense fuchsite alteration and moderate quartz veining occurring in proximity to the anorthosite contact. An anomalous gold assay of 0.038 oz/ton was reported by Weidner (1987) from a grab sample of quartz vein material. Significant sulphide mineralization does not occur in the veins, with pyrite only observed rarely.
