Geologic setting

Geologic description

The Sheep Creek occurrence consists of sphalerite in small lenses along shear zones in dikes near the north side of a small stock. The stock intrudes limestone and siltstone of the mid-Silurian Terra Cotta Mountains Sandstone, a formation within the Dillinger sub-terrane (Bundtzen, Harris, and Gilbert, 1997). According to Reed and Elliott (1968), selected grab samples contain up to 5.00 percent zinc.
In 2008, this prospect was one of several in a block of claims that covered more than 70 square miles, known collectively as the BMP project (International Tower Hill Mines, Ltd., 2008).
