The Marg deposit is a polymetallic (zinc, lead, copper, gold and silver), volcanic hosted massive sulphide deposit (VMS deposit). It is hosted within Devonian to Mississippian felsic volcanics, and associated carbonaceous mudstones of the Earn Group. Mineralization at Marg consists of a series of continuous to discontinuous, subparallel sheets of massive to semi massive sulphide at or near the contact between the hanging wall carbonaceous mudstones and footwall felsic volcanics. Sulphide minerals include pyrite, sphalerite, chalcopyrite, galena, tetrahedrite and arsenopyrite in a gangue of quartz, ferroan carbonate, muscovite and rare barite.
In 2013, Redtail Metals carried out a mineral resource estimation and estimated:
An Indicated Resource of: 3.96 MT at 1.57% Cu, 1.92% Pb, 3.90% Zn, 49.40 g/t Ag, and 0.79 g/t Au
And an Inferred Resource : 7.70 MT at 1.12% Cu, 1.36% Pb, 2.89% Zn, 34.88 g/t Ag, and 0.52 g/t Au
The Marg deposit is located approximately 75km northeast of Mayo, Yukon Territory, Canada and is accessible via winter trail from Keno City, helicopter or a small airstrip located on the property.
