Status: Developed Prospect
The area is underlain by rocks of the (?)Hadrynian-Paleozoic Snowshoe Group of the Barkerville Terrane. Fluorite mineralization is contained in quartz-feldspar-mica gneiss injected with masses of pegmatite, aplite and granitic rock of normal texture. The gneiss is overlain by biotite schist. Foliation in the gneiss strikes east to northeast and dips 35 to 45 degrees north. The gneiss is highly fractured by numerous joints and faults which are generally either near vertical and striking north to slightly west of north, or vertical to steeply southeast dipping and striking northeast.
Fluorite occurs as grains disseminated in the country rock, as thin films on fractures, as veinlets and scattered veins up to 15 centimetres wide, and as pods and irregular masses 15 to 20 centimetres wide. Drilling results seem to indicate a series of steeply dipping north to northeast trending zones of mineralization with an enriched zone adjacent to the footwall or lower contact of the mineralized gneiss. The mineralized zone extends 1500 metres in an east-west direction and 900 metres in a north-south direction. In addition to fluorite, mineralization consists of galena, sphalerite, molybdenite, celestite, pyrite and associated silver. Gangue minerals consist of quartz, calcite, dickite and allanite. Chloritic, sericitic and potassic alteration with associated biotite and epidote are evident in the area. An age date on fluorite using fission track methods resulted in a date of 104.6 Ma +/- 6 Ma (Fieldwork, 1988).
Indicated (probable) reserves are 24 million tonnes grading 11.5 per cent fluorite (CaF2) (Eaglet Mines Ltd. Annual Report 1984).
