Capsule Geology

Poorly exposed, centimetre-scale veinlet cross-cutting massive, dark grey or green volcanic breccia of the Upper Triassic Stuhini Group. The occurrence is actually in the creek, so outcrop of the sample locality is poor. A grab sample of the veinlet (maximum width less then 0.5 centimetres) and surrounding altered wallrock yielded 312 parts per billion gold, 12.0 parts per million silver, and 0.50 per cent copper. Veinlet mineralogy includes quartz, pyrite, chalcopyrite, and possibly hematitic staining. The immediate wallrock is chloritic and in part stained pink (potassic alteration?).
