The CAMP HEWITT 8 showing is located on the northeast side of Pincushion Mountain, approximately 1.2 kilometres northwest of Pincushion Bay.

The showing consists of small shears and quartz veins in greenstone of the Triassic-Jurassic Nicola Group. The area is covered by rhyolite, trachyandesite and andesite flows of the Eocene Marron Formation (Penticton Group) except in the Trepanier Creek valley where the Nicola Group rocks are exposed. Granodiorite of the Early Jurassic Pennask Batholith is found a short distance to the west.

An old 3.6-metre shaft is attributed to the Camp Hewitt Mining and Development Company which was active in this area during the period 1896-99. The shaft exposes several small shears striking northeast to north-northeast and dipping steeply to the southeast. Irregular quartz lenses with pyrite are found within the shears. Disseminated pyrite is found in the greenstone between shears. Occasional small lenses of galena with minor sphalerite are also noted. In 1965, Quinalta Petroleum Ltd. drilled a 35-metre diamond-drill hole at this location. There is no record of the hole intersecting mineralization.

In 1972, Vega mines Ltd. carried out a soil geochemical survey centred over the CAMP HEWITT 3 (082ENW022) area 1.2 kilometres to the southwest; copper and zinc anomalies were found. In 1984, Charles Brett funded a VLF-EM survey over the same general area. The survey was able to identify gross lithological features, but was not useful in defining shear zones.
