Structure: Nw-Trending Fault That Offsets Ash-Flow Tuff Sequence.
Alteration: Silicification, Kaolinization, Alunitization; Argillized.
Commodity: Project 9350 - 01393 alunite resources; Au to Ag ratio 1:1
Deposit: See record m233181, golden pen gold mine, for information on gold deposit at this site. ; info.src : 1 pub lit; 3 field observ main quartz vein varies from 3 to 10 ft. Thick, but the alunite is found in sheets separating the vein from the wall rock. These sheets are 3 inches to 1 ft. Wide. Size/directional data given is for alunite deposit only. Vein emplaced along nw-trending fault.
Deposit type: Epithermal vein, Comstock
Development: Early works for gold (1908 and later); 1936 a portion of the property was leased to w.b. Worlock who made two small shipments.
Geology: Thin alunite vein replaces gouge (?) in sericitized rhyolitic tuff. Quartz veins 3-8 ft. Wide, milky and vuggy As well As brecciated. Separated from walls of post esmeralda(?) volcanic rocks by alunite sheets 3-12 inches thick.
Ore(s): Nw-Trending Fault; Ore Mainly On Hanging Wall Of Fault Zones Up To 50 Ft. Wide.
