"Husson (2003; GM60474) also identified quartzofeldspar/granite porphyry (?) sills, oriented parallel to the gabbro/amphibolite schistosity. The sills are medium-grained, composed of quartz (60%), feldspar (40%), and rare biotite and muscovite crystals. In the field, we observed granitic pegmatite dykes and bodies, mainly outcropping on the gold occurrences of the South Zone (e.g., Oeil, Granite, Désirée, and Cache-à-L'Ours). Megascopically, these exhibit a mineralogical assemblage consisting of feldspar (potassium and plagioclase), quartz, biotite, and ± muscovite. The contact between sills and volcano-sedimentary units is often marked by sulfide-rich zones."

GM70706 Conclusion:
"In the South Zone, visible gold is noted on at least three significant showings and high Au grades in association with deformed/mylonitized metavolcanic/metasedimentary rocks rich in pyrrhotite: e.g., 167 g/t, 33 g/t, 24.8 g/t, and 4.8 g/t. When significant data from SOQUEM and Stelmine on selected samples are incorporated, concentrations of 0.35 to 24.80 g/t Au are obtained, producing an average of 3.65 g/t (32 samples), excluding a value of 167 g/t. The abundance of conglomeratic units accompanied by the presence of fuchsite in association with sulfide rocks, ultramafic sills, silicified protoliths, and arenite/quartzite bands indicates significant hydrothermal alteration possibly associated with gold mineralization."Link to GM70706 reportStelmine 2022: Zone 4 Target (Zone Sud)"The Zone 4 Target (Figure 1) area covers an 800 m strike length with channel sampling returning results of 167 g/t Au over 0.5 m and 4.0 g/t from a 1.3 m.
Only two holes were completed at Zone 4 with one hole returning 2.0 m at an average grade of 0.78g/t Au from 52.5 m (STH21-COU014), highlighting the potential for additional drilling to define further gold mineralisation at this target."
