On either side of the fault, country rock has been strongly sheared over distances of up to 400 m from the fault. This northwestern limb of the MDdz is 25 km long and 2 to 5 km in width and hosts the majority of the known gold occurrences.
Excellent Bulk Sample Results & Metallurgy
Gold is concentrated in the “crackseal” fractures and in selvedges along the quartz vein margins. Calcite filled fractures within quartz veins also carry gold. Narrow gold-bearing semi-massive sulphide filled fractures within fissile zones also contain significant gold values. Pervasive ferroan carbonate alteration, disseminated sulphides, and very small barren quartz veinlets characterize the fissile zones.
Sulphides are predominantly pyrite, with variable amounts of chalcopyrite. The gold tenor appears to be related to the quantity of pyrite present in the wall rock and in veins.
