Geologic setting

Geologic description

The rocks in the area consist of Silurian or Ordovician basaltic to andesitic volcanic rocks of the Descon Formation, and Ordovician granodiorite and diorite (MacKevett, 1963; Gehrels, 1992). Near the prospect, both units are offset by a north-northwest-trending fault. The deposit is in highly fractured, metavolcanic rocks and consists of gold-bearing calcite veins that contain pyrite, chlorite, and secondary iron oxides.
