Geologic setting

Geologic description

The rocks in the vicinity of this occurrence are Paleozoic amphibolite-facies paragneiss, quartzite, schist, and amphibolite and Mississippian to Devonian augen gneiss (Werdon and others, 2001). These units are cut by a prominent, northeast-trending, high-angle fault that can be seen as a topographic linear in air photos. An assay of a calcite-veined breccia with igneous-textured clasts (probably augen gneiss) from this fault contains 75 ppb gold (Szumigala and others, 2000).
