Pyrrhotite Gold Musselwhite Mine Cyanidation
Overview | Romios Gold Resources Inc.
Drilling on NW claims discovered the most significant gold intercept in the belt outside of the Musselwhite mine property: g/t Au / m in a quartz(pyrrhotite) vein. Several large, coarsegrained, "epithermallooking" calcite veins up to m wide, +/ gold values up to g/t Au/ m, occur near the goldquartz vein(s).
