The Amulet Mine, Que.

CIM Bulletin1930
THOSE who have followed the geological developments in connection with the copper deposits of Quebec will recall that on many properties the sulphide bodies occur as replacements of fault breccias or tuff breccias, and exhibit a pronounced distaste for the more massive lavas. At the same time the rocks around the orebodies are profundly altered, first by addition of silica and sericite, later by conversion of these minerals into chlorite.
