The Knob Hill showing is located 2 kilometres southwest of August Lake and 5 kilometres southeast of Princeton.
A mass of resistant syenodiorite projects above the surrounding overburden, forming a small hill known locally as Knob Hill. The syenodiorite outcrops over an area 1000 metres long and up to 600 metres wide. This intrusive body appears to be related to the Early Jurassic Lost Horse Intrusions, occurring in the vicinity of Copper Mountain to the southwest.
Some quartz-carbonate veins, containing chalcopyrite, occur on Knob Hill. Two grab (?) samples assayed 0.99 and 0.51 gram per tonne gold, 33.6 and 49.0 grams per tonne silver, and 0.60 and 1.22 per cent copper, respectively (Assessment Report 12736, South zone geochemistry map).
Various operators conducted surface exploration over the showing between 1966 and 1988. Knob Hill Explorations Ltd. drilled one hole in 1971.
