Bundle Description

43 till samples collected in 1994 from Natapulik Lake (NTS 86I) were picked for gold grains by Overburden Drilling Management, Ottawa, Ontario in 1995. Prescreened samples were disaggregated in water and sieved to < 1 mm. Heavy minerals were concentrated using a shaking table. The HMC concentrate was panned and gold grains were counted and classified based on their shape.

These data are published in GSC Open File 3316.
