The Redfern occurrence is located on the northern slopes of Spanish Creek, approximately 7 kilometres south-southwest of Spanish Lake.

The area is underlain by quartz-mica schists, calc-silicate schists, quartz biotite schists, quartzites and minor marbles of the Proterozoic-Paleozoic Snowshoe Group.

Locally, limonite-stained white quartz veins, up to 1.4 metres wide, carrying rare galena-pyrite mineralization in the form of sporadic blebs and disseminations are hosted in a highly altered calcareous quartzite or phyllite, also carrying finely disseminated pyrite and minor galena.

Between 1987 and 1990, D.W. Ridley conducted various programs of geochemical sampling, prospecting, geological mapping, trenching and a geophysical survey on the property. In 1990, a 2.0 metre rock chip sample across the vein and wall rock returned values of 13,874 parts per million lead, 1,077 parts per million zinc and 50.2 parts per million silver (Assessment Report 21013).
