Hole BR25-002 at 125m. (A) Closeup of massive pyrrhotite > chalcopyrite in skarn zone approaching contact with a thick granodiorite dyke. (B) Mineral assemblage appears to be dominantly chlorite-quartz with zones of massive and clustered sulfide Pyrrhotite > Chalcopyrite, changing to chalcopyrite dominant downhole.
