Abstract: The Fer gold property lies only 5 kilometres southwest of the Nahanni Range Road (Highway 10) in southeastern Yukon. It is underlain by a broadly folded sequence of coarse siliciclastic, calcareous and phyllitic, continental margin sedimentary rocks of the Neoproterozoic to Lower Cambrian Hyland Group. The extensive belt of Hyland Group rocks hosts gold mineralization in numerous occurrences from southeastern Yukon to the Dawson City area and is part of the Tintina gold belt.

The Fer property was originally staked in 1996 to cover the largest cluster of gold anomalies (>90th percentile for gold) in a regional fine-stream-sediment sampling program. Soil geochemistry on the property has outlined an area of about 2000 by 500 metres in the Southern Grid area with anomalous gold and arsenic values (>25 ppb Au, >125 ppm As). These values range up to 1870 ppb Au and 5430 ppm As. As well, a 500 by 200 metre Au-As anomaly is present in the Northeast Grid.

Mineralization is largely controlled by structure and host rock lithology, and is spatially associated with the most intense zones of silicification and quartz vein stockwork. Gold correlates best with As, Ag, Pb, and Sb. Values up to 2.3 g/t Au have been found in select rock samples in the mineralized areas. The Fer property mineralization likely represents a distal end-member of the plutonic-related gold deposits in the Tintina gold belt.
