KATX and Vale targets that elsewhere in the world have proved to be major sources of copper
A similar environment appears to be present in the Newfoundland Avalon Zone where native copper– bornite–chalcocite mineralization is present in redbed–basalt units of the Neoproterozoic Musgravetown Group on the west side of Placentia Bay (e.g., Rocky Cove prospect, Figure 2), near Bonavista Bay (Princess and Red Cliff prospects, Figure 2), and also in basalts of the Harbour Main Group near St. John’s.
The sediment-hosted environments, notably the redbed and volcanic redbed environments, represent promising grass-roots targets that elsewhere in the world have proved to be major sources of copper. The porphyry environment is also an underexplored grass-roots target that may have considerable further potential, particularly in the granitoid batholiths that comprise much of the Newfoundland south coast. The possible association of Cu–Au, or Fe oxide–Cu–Au, porphyry mineralization with the epithermal systems of the Avalon Zone is also a promising target for a large part of the central and western Avalon Zone
