Mineralization Comments

Sep 25, 2023 (Shirley Peloquin) - There is no specific information on Platinum Hill. However, it is along strike to the East from BP Resources' D-zone. D-zone is described as within the marginal leucogabbronorite, about 50-100m south of the country rock granite contact. The zone is 260m long. It is open to the west; BP did not consider the eastern extension (toward Platinum Hill) to be mineralized.
