The ore is in quartz in silicified brecciated zones striking N with a steep dip. Ore pinches and swells rapidly. Alteraton is silicification. Host rocks are Deception rhyolite and quartz porphyry.
Openings are some 600 feet of workings to 100 feet deep. Production was some 5,000 tons of ore valued at $15 ton (before 1900).
