The prospect occurs in siliceous sandstone of the Lower Cretaceous Skeena Group, Kitsun Formation. The sediments are intruded by a swarm of leucocratic quartz feldspar porphyry dikes which range from 4.5 to 6.0 metres in width and have caused selective hornfelsing.

Mineralization is found throughout the sediments as disseminated and blebs of pyrite in fractures and within quartz and quartz- carbonate veinlets. Some molybdenite and minor chalcopyrite occur along fractures in the intrusive dikes and hornfels (refer to 093L 136 - Reiseter 5). Other quartz veins in the area host stib- nite, sphalerite, galena and minor chalcopyrite (refer to 093L 134 - Reiseter).

Mapping in 1988 uncovered an old trench which hosts blebs and disseminated pyrite in quartz stockworks within siliceous sandstone. Sample APE 88-25-1, taken from a quartz vein with pyrite assayed 6.84 grams per tonne gold, 218.0 grams per tonne silver and 0.087 per cent copper. Sample APE 88-25, taken across the vein including some country rock, assayed 0.002 grams per tonne gold, 0.007 per cent copper and 0.001 per cent zinc (Personal Comments: P.A. Desjardin, Fieldwork, 1988).
