Mar 11, 2019 (Sheree Hinz) - The local geology of the deposit was mapped by Carter who outlined a northwest-trending band of dolomitic marble at the contact between calcitic marbles and syenite. Mineralization is hosted in the dolomitic marble, a white, medium-grained massive rock containing minor fine-grained graphite and serpentine. The syenite is a reddish coloured, very fine-grained massive rock containing small clots of fine-grained mafic minerals. It is cut by narrow veinlets of very fine-grained epidote. The last recognizable unit is a white, massive medium-grained calcitic marble with minor disseminated graphite and brucite.

Mar 11, 2019 (Sheree Hinz) - Narrow mineralized zone (10-20 cm), contorted layer of heavily disseminated to massive sphalerite. Low silver content. Two chip samples were analyzed by Carter in 1985 and got returns of: 45.6% Zn, 425ppm Cu, 345ppm Pb, 1260ppm Cd, 0.24 oz/ton Ag for sample 81 TRC-22, AND 3.58% Zn, 74ppm Cu, 30ppm Pb, 17ppm Cd for sample 81 TRC-23.
