Abstract: An integrated bedrock mapping and regional soil sampling program in the Mount Mervyn map area (106C/04) was undertaken in 2010. It is the first year of a multi-year initiative called the South Wernecke mapping project (SWP), which will cover ten 1:50K map sheets in the southern Wernecke Mountains area in central Yukon. Field work in the first year served to highlight the complexities of the bedrock geology in the region, and identify areas of mineral potential.

The Mount Mervyn map sheet is underlain by Proterozoic and Paleozoic siliciclastic and carbonate rocks that have been deformed into an east-trending fold-and-thrust belt. Regional soil geochemical data coupled with bedrock observations highlight new areas of mineral potential (i.e., Ni and Au) that have not been previously identified.
