The Myah vein has a general strike of N43E, and dips 55NW to vertical. The vein is formed by replacement of sheared granite along a minor fault zone. It is a composite of discontinuous stringers of quartz, pyrite, and chalcopyrite and ranges in width from a few inches to about 3 feet (1 meter).

Workings include a drift adit and an inclined shaft from which drifts have been driven on the 65, 130, and 180 foot levels.
