Chris Taylor, President and CEO of Great Bear said, “In a district where gold is usually mined from discontinuous veins averaging a few metres in width, often at kilometre-scale depths, the near-surface, multi-kilometre extent of our LP Fault discovery instead resembles other Archean-age gold deposits across Ontario and Quebec. We continue to intersect high-grade gold intervals with comparable widths and grades to what have been mined at the major high-grade deposits in Red Lake, however these occur within wide envelopes of moderate to low grade gold mineralization, which we observe projecting to surface. During September and October, mapping crews discovered outcrop exposures of our felsic target geology, similar to what we’re drilling from Bear-Rimini to Auro, along approximately 15 kilometres of strike length. We have also now drilled the same units one kilometre to the southeast of the Auro zone, with assays pending, and through examination of historical drill core we see that Noranda in 1993, drilled similar rocks 8 kilometres to the southeast of the Auro zone.”
Noranda Report – 1993
Hole P-93-2 was drilled to a depth of 147.0m and was designed to test the conductor mentioned above. The hole intersected intermediate bedded to massive pyroclastic ash tuffs/lapilli tuffs. Locally, strong chlorite-carbonate mineral assemblages are observed. From 105.4m-118.1 m, 5-15^ disseminated to stringer Po-Py mineralization with trace chalcopyrite was intersected corresponding to the down dip projection of the conductor axis. No significant assays were returned.
The drill program confirmed the presence of intermediate pyroclastic volcanic rocks similar to that observed at the Dixie deposits to the east. The conductor was explained by a 12.7m interval of disseminated to stringer Po-Py mineralization, however, no significant assays were returned. Lithogeochemical sampling failed to identify favourable alteration (ie. Na-depletion, Mg-enrichment) typical of a VMS hydrothermal system.
