There are minor amounts of pyrite and subhedral chalcopyrite crystals. Malachite is uncommon as thin coatings or tufts of acicular crystals. Pedro claim Pedro is located below the Katie Belle breccia in a very steep cliffy area. This claim has been commercially mined for specimens. Cavities are generally less common and smaller than those at Spruce, mostly 15-30 cm long.
Quartz scepters are common in parts of the breccia as are Japan law twins.
Quartz crystals are often brilliant and may contain pyrite and tiny green and black spherical inclusions, sometimes forming phantoms. Pyrite crystals are numerous and occur both as modified cubes with striations and growth hillocks, or as composite crystals formed from many oriented small cubes. Most are less than 3 cm across. Chalcopyrite is uncommon, but has been found to 6 cm. Galena forms small crystals or rarely stalactites.
