The GM occurrence was discovered by partners Mel Zeiler and Gary Toop by prospecting in 2000.

The GM area is underlain by rocks of the Hadrynian or Paleozoic Snowshoe Group, Barkerville Terrane. The rocks are comprised of quartz mica schist and micaceous quartzites, pyritiferous argillite and phyllites. The showing comprises a 1 metre wide quartz-carbonate vein and stockwork zone exposed in two excavator trenches spaced 40 metres apart. Mineralization consists of disseminated to locally massive galena and minor pyrite, sphalerite and chalcopyrite. Galena is also disseminated in siliceous bands within crenulated to gently folded metasediments adjacent to the vein structure, and exposed in a road cut below the trenches. The vein is subvertical and has a strike of about 140 degrees.

A grab sample of quartz vein with 3 to 4 per cent galena assayed: 0.79 gram per tonne gold, 134.6 gram per tonne silver and greater than 1 per cent lead (Personal Communication, Robert Lane, 2001).
