The Friendship occurrence is located on the south side of Penstock Creek, approximately 1.5 kilometres southeast of its confluence with Winslow Creek.

The area is underlain by granodioritic intrusive rocks of the Tertiary to Jurassic Coast Plutonic Complex.

Locally, two forms of mineralization are present. The first, and most prominent, consists of aggregates, of hornblende, biotite and pyrite with minor chalcopyrite and rare molybdenite, ranging from 0.25 to 2.5 centimetres in diameter. The second form of mineralization consists of quartz veins and fractures, up to 7.5 centimetres wide, hosting patches, smears and rosettes of molybdenum with minor chalcopyrite. The veins trend 168 degrees and dip 65 degrees west. Both forms of mineralization are hosted by highly fractured and altered granodiorite to quartz diorite.

In 1966, diamond drilling is reported to have yielded up to 1.9 per cent copper or molybdenum over 22.5 metres (Property File - Esperanza Explorations Ltd. [1980-02-01]: Property Examination Report - The Winslow Creek Project).

In 1979, two grab samples (718 and 719) of the first style of mineralization assayed 0.153 and 0.157 per cent copper, respectively (Property File - Esperanza Explorations Ltd. [1980-02-01]: Property Examination Report - The Winslow Creek Project).

A short, 3-metre adit of unknown age is reported. In 1966, New Jersey Zinc Exploration Company (Canada) Ltd. carried out 709 metres of diamond drilling in five holes. In 1980, Esperanza Explorations examined the area.
