Capsule Geology

The Amic (Yukon) claims are located on a new showing discovered in 1982 when following up a stream sediment anomaly using a heavy metal kit. A vein with 300 metres strike length and a fissure zone were found striking 045 degrees and dipping almost vertically. The vein and fissure are hosted in the Mine stock, part of the Nelson intrusions of Middle Jurassic age, described in Geological Survey of Canada Memoir 228 as calcic biotite amphibole granite and thus distinct from the Bayonne batholith to the south, which does not contain significant amphibole. However, the mineralization may be related to the middle Cretaceous Bayonne batholith, which is post-amphibolite grade metamorphism.

The quartz vein and the fissure contain galena, pyrite and sphalerite as small pockets; assays of up to 0.67 per cent lead, 0.13 per cent zinc, 23 grams per tonne silver and 19.5 grams per tonne gold occur in vein float and outcrop over up to 25 centimetres width (Assessment Report 11026).

Geochemical surveying and trenching by Cima Resources Ltd. in 1982 revealed the presence of several subsidiary veins with similar strike on the property.

Bluebird Minerals Ltd. drilled 6 holes totalling 1132 metres in 1997.
