The Property is underlain by the northeast portion of the Tulks Volcanic Belt; an informally named formation belonging to the Victoria Lake Group. Regionally, the 498 Ma sequence consists of felsic pyroclastics and flows with interbedded mafic volcanic units and fine grained, commonly graphitic, sediments. The felsic volcanic rocks are typically dacitic to rhyolitic in composition.
At the north end of the belt, mafic volcanic rocks dated at 462 Ma are typically calc-alkaline which contracts with the tholeiitic affinity of the Tulks Belt. Work by BP geologists indicated that this sequence is in fault contact with the Tulks Volcanics belt in the vicinity of the Victoria Mines. These younger rocks, termed the Victoria Mines Sequence may in fact belong to the Buchans Group rather than the Victoria Lake Group.
The northern portion of the Tulks Belt hosts 4 significant volcanogenic massive sulphide deposits; Jack’s Pond, Daniel’s Pond, Bobby’s Pond and Victoria Mines as well as numerous showings such as the Roebuck, Sutherland Alteration Zones and the Parking Lot Showing.
