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 geophyscis, 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 based on the reported intersection of anomalous concentrations of copper and zinc in Castlebar Silver and Cobalt Mines/Sulmac Exploration Services' 1960 diamond drill hole No. 3 (AFRI# 52O12SE0024). The diamond drill hole log indicates that the stratigraphy at this location is dominated by metavolcanic rock logged as andesite. Significant sections were also logged as banded siliceous tuff and rhyolite. Sulphide mineralization was reported throughout the approximately 100 m drill section, with two significant sections of massive sulphide. The widest of these massive sulphide intersections was encountered approximately 55 m from the top of the hole and was 2.2 m wide. Sulphide minerals that were logged included pyrrhotite, pyrite and chalcopyrite. Fenwick (1969) mapped clastic metasedimentary (siltstone/argillite), iron formation and mafic metavolcanic rock units in the area of this occurrence. Fenwick (1969) indicates a sedimentary bedding orientation of approximately 060/80, as well as a nearby occurrence of mineralized float containing pyrite, chalcopyrite and bornite. Numerous anomalous zinc and copper assays were reported from the upper 55 m of the drill hole, with the most significant being 2.18% Zn over 0.7 m and 0.26% Cu over 0.36 m.
