Is gold found in schist?
Visible gold occurs in small irregular grains and wires in quartz without associated sulfides (fig. 7A) and in pyrite, both in the veins and in the altered schist in shear zones, even where quartz is absent (fig. 7B). Scattered grains are also found in the sulfide-bearing schist adjacent to the quartz veins.
