Mineralization Comments

Nov 29, 2022 (Therese Pettigrew) - The bands of sulphide-graphite mineralization are evident as magnetic highs and time domain electromagnetic anomalies on airborne geophysical surveys. Samples of quartz-biotite gneiss, quartz-feldspar-biotite-gneiss, and rusty quartz-feldspar-phlogopite schist containing up to 7% graphite (visual estimate) and minor pyrite were collected. Sample JM-17-13 returned 2.77% graphite (Assessment report 20000017976).
