Survey Description
During the 2016 and 2017 field seasons, till samples were collected in frost boils at an average depth of 34 cm for indicators minerals (10 kg) and till geochemistry (3 kg). Sixty-one samples were collected in four transects parallel to the main ice-flow direction (NNW) with samples collected up-ice, over and down-ice of mineralization. The transects were centered on known arsenic anomalies defined from a previous detailed till survey by Agnico Eagles Mines Ltd.
A vertical profile in a frost boil on each transect was sampled for geochemistry (3 kg) at 10 centimeters intervals from the surface to a maximum depth of 115 cm. A 10 kg sample was also collected for each profile at ~33 cm depth.
The data are published in Victor de Bronac de Vazelhes’ MSc thesis at the Université Laval. The work is also mentioned in Geologial Survey of Canada Open File 8651.
In order to assess the gold grain count background, 19 regional samples were collected but the results from these samples are not reported.
