The Silver showing, later a part of the Altroy Group (Marmot Grid), is located on a tributary of Lavington Creek. The showing was originally explored in the 1920's and 1930's before re-newed exploration in 1990's. In 1995, a program of geological mapping, reconnaissance VLF-EM and magnetometer and geochemical surveys were completed.

At the Silver showing, oxidized galena, sphalerite and pyrite occur within a highly faulted and fractured shear zone which strikes generally north and dips steeply to the west. The shear zone occurs in recessive Kitchener Formation rocks of finely bedded, rusty weathering, vari-coloured (red, purple and green) argillite-smite metasediments. Much of the succession is dolomitic and altered Carbonate is present in the mineralised zones.

During the period, 1926 through 1934, trenching in the oxidized metasediments disclosed disseminated sulphide and oxide mineralization with silver values in the amount of 102 to 364 grams per tonne, 0.7 to 1.4 gram of tonne gold, 13 to 22 per cent lead and 10 to 26 per cent zinc (Assessment Report 26145).

In 1993, a sample of outcrop returned up to 0.34 gram per tonne gold, 1157 grams per tonne silver, 204 parts per million copper, 23.00 per cent lead and 40,823 parts per million zinc (Assessment Report 23409).

In 1995, rock samples returned up to 18.5 per cent lead, 15.10 per cent zinc and 652.2 grams per tonne silver. Another sample, from the same area, returned 3.26 per cent lead and 9.01 per cent silver (Assessment Report 24427).
