Cavities at pedro generally are not collapsed as at the other breccia bodies, but are solid making extraction of fine matrix specimens difficult. Big Chief claim Below Pedro, there is another breccia body with similar characteristics. This deposit has not been commercially mined, but is being worked by the claim owners. Quartz forms stubby to elongated crystals, often sceptered, with some amethystine crystals. Japan law twins are uncommon.
Some crystals contain chlorite inclusions and phantoms formed by fluid inclusions.
Pyrite is uncommon and is usually oxidized. Minor amounts of tiny crystals of anatase, brookite, and hematite have also been found. Other breccia bodies Other breccia bodies that have produced some quartz specimens in this area are Clipper , Condor and Porter .
