Structure: Faults
Commodity: Part of ore is dark, greenish-gray, compact, but grades into partly chloritized igneous rock. Rest of ore is a breccia consisting of rounded fragments of compact material in a fine-grained flakey, sheared matrrix.
Deposit: Vertical zone of faulting and chloritization in porphyritic quartz diorite and quartz monzonite. On NE side of road is another similar 30-ft zone of partly chloritized impure material.
Development: Stripping, trenching
Rock formation(s): Sylvania Pluton
Ore(s): Vertical Fault Zone
