The MM showing is located on the east bank of Many Creek, approximately 1.5 kilometres northeast of Mount Madge and at an elevation of 800 metres. The showing is a mylonitic zone in andesite volcanic rocks of the Middle Jurassic Salmon River Formation, Hazelton Group. It has been traced for over 50 metres and is up to 25 metres wide.

Mineralization occurs andesitic tuff, marked by a wide zone of ductile deformation and cataclasis. Alteration is intense, with pervasive bands and pods of ankerite, fuchsite, quartz-carbonate, sericite and pyrite. These rocks host sulphide mineralization as disseminations, vein stockworks and bands of sphalerite, galena, arsenopyrite, minor chalcopyrite, trace tetrahedrite and pyrite. Peripheral alteration consists of chlorite and ferrous carbonate. Cross cutting zones of shearing trends both parallel and at right angles to Mandy Creek.

Three trenches were excavated in 1993 over an exposed length of 50 metres and 25 metres width. A total of 17, one metre chip samples were taken with mixed results. Trench 101 yielded a wide zone of anomalous but uneconomic values. The most significant chip sample assayed 1.17 grams per tonne gold and 0.25 per cent zinc across 1 metre (Assessment Report 23805).
