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.
