Gold grains in till samples from the southern Core Zone, Quebec and Newfoundland and Labrador (NTS 23-P and 23-I): M183-2/8222E-PDF

potential for undiscovered mineralization /

"This report presents the indicator mineral content of till samples (n=86) collected during the summer of 2016, in the southern sector of the Core Zone located within Woods Lake (NTS 23-I) and Lac Résolution (NTS 23-P) map areas, approximately 50 km east of Shefferville, Quebec. Of potential interest for mineral exploration in this region is the presence of gold grains (7 to 63 grains /10 kg) in 15 till samples principally collected over the Doublet Zone mafic volcanic rocks. One sample located over the Core Zone orthogneiss contains a noticeably large sand-sized gold grain, which is in contrast with the silt-sized gold particles in the other till samples. The source(s) of gold in the till is unknown. The 2016 till sampling survey was the third of three field seasons of reconnaissance-scale surficial mapping and till sampling in the south part of the Core Zone and was conducted as part of the GSC’s Core Zone Surficial Activity (2014–2017) of the Geomapping for Energy and Minerals 2 (GEM 2) Program. Indicator mineral results for the 2014 and 2015 till samples, which were originally presented in McClenaghan et al. (2016) and Rice et al. (2017), are included for completeness"--Abstract, p. [1].
