The United Copper showing is located approximately 1.5 kilometres south west of Sawyer Pass, at an elevation of 1992 metres.
The area is primarily underlain by siltstone, argillite, quartzite and dolomite of the Middle Proterozoic Dutch Creek Formation (Purcell Supergroup). Phyllite, quartzite and grit of the Upper Proterozoic Horsethief Creek Group (Windermere Supergroup) and quartz arenite sedimentary rocks of the Middle Proterozoic Mount Nelson Formation (Purcell Supergroup) outcrop to the east and west.
Locally, quartz veins and inclusions containing chalcopyrite, sphalerite, galena, pyrite and pyrrhotite occur along a shear zone in foliated zones with in a chlorite schist or laminated argillite. Bornite with silver minerals occurs as replacements in limestone. The vein strikes north 30 degrees east and dips 57 degrees east and has been exposed by surface stripping for a distance of approximately 300 metres. The vein varies from approximately 30 centimetres wide at the north end to a 5 centimetres wide at the south end and reaches a maximum width of 2.5 metres with an average width of 1.1 metres.
Two other, parallel, quartz vein systems have been exposed by stripping, open-cuts and small drifts approximately 300 metres west and 150 metres lower in elevation and 450 metres west of the main vein. These veins vary from 5 to 60 centimetres in width over strike lengths of 1.5 metres.
In 2008, a 1.08-metre wide chip sample (UCR08-01) assayed 0.774 per cent copper, 0.015 per cent lead, 0.13 gram per tonne gold and 4.5 grams per tonne silver, while a grab sample (UCR08-02) assayed 0.16 gram per tonne gold, 6.2 grams per tonne silver and greater than 1.0 per cent copper (Assessment Report 30380).
The property was reportedly drilled in the early 1970’s. In 2008, a minor program of rock sampling and prospecting was completed.
