Lithology Comments

Jun 11, 2021 (Sheree Hinz) - The property is underlain by biotite and granite gneisses of the Cross Lake granite gneiss mass, and by a thin band of easterly-trending biotite-hornblende gneiss. Radioactivity occurs in east-west trending pegmatite dikes.

Mineralization Comments

Jun 11, 2021 (Sheree Hinz) - The dikes consist of medium- to- coarse-grained pink pegmatite with approximately 10% biotite, often in well-developed crystals. A bulk sample from a dyke (near the centre of the E half of lot 6, con 1) assayed 0.051% U3O8 (chemical), nil ThO2. The best bulk sample from a trench assayed 0.062% U3O8 and 0.05% ThO2.
