Preliminary field investigations began in 2011, and bedrock mapping began the following year at Sharrie Lake, east of Yellowknife. In 2013 and 2014 bedrock mapping continued at Sharrie Lake and in the Snare River and Indin Lake areas, north of Yellowknife. Geochemical studies, regional age dating, and further preliminary field investigations has been ongoing since 2012. The extensive forest fires in 2014 exposed bedrock in the volcanic belt areas, which will greatly increase the ability to map these areas. The surficial sediment sampling related to VMS exposures will begin during the 2016 field work focused on the Grenville Lake and Indin Lake areas.
