Capsule Geology

The area is underlain by a "trachytic" unit of alkali-feldspar porphyry, lithic tuff, tuff breccia and pyritic schist of Unit EBFt of the Devonian to Mississippian part of the Eagle Bay Assemblage. The trachytic unit is structurally underlain by quartz-sericite schist, chlorite schist and interlayered metasediments. High-angle northerly trending faults sharply control the distribution of the trachyte unit.

Molybdenite, fluorite, uranium and thorium minerals, likely uraninite and uranothorite, occur in the trachytic unit mainly associated with pyrite and mica. Drilling intersected 0.230 per cent MoS2 over 6 metres in one hole and 0.014 per cent uranium over 6.7 metres and 9.2 per cent CaF2 over 3 metres in a hole 100 metres to the northeast. A further 400 metres to the northeast a hole intersected 0.16 per cent ThO2 over 6 metres and another hole intersected 0.014 per cent uranium over 17.6 metres (Property File, Report by P. Pisani, 1970).
