Structure: Fracturing Trends Generally Nw. Thin Series Of Andesite Breccia Overlain By Rhyolite Indicates Fault Contact With Andesite

Alteration: Bleached Andesite And Development Of Jarosite Due To Oxidation Of Numerous Sml. Xstls. Of Disseminated Pyrite

Commodity: Due to presence of mn, zone of secondary enrichment extends belo W the 250' level. Some Ag alloyed w/au, ration Au to Ag 30:1 . The average assay value of a number of samples was .78 oz. Gold and 36.7 ozs silver which converts to $59.65 per ton, gold at $20 per oz. And silver at $1.20 per oz.

Deposit: Estimate location. Deposit is oxidized and highly siliceous seven lode claims: last hope, l. H. Fraction, thomas fraction, l. H. Extension no. 1 , hope extension no. 1 and no. 2 . Approx. 110 acres. 30 ft. Head frame, blacksmith shop, assay office on site. A mill proximal to mine with 40 to 50 ton capacity and cyanide leaching system; h20 at 160 : refer to record no. M035745 ; info.src : 1 pub lit; 2 unpub rept

Deposit type: Epithermal vein, Comstock

Geology: Richest ore occurred in lenses in iron-stained qtz. Gangue in sheared volcanics. Crushed rock carries good value while gouge is low grade or barren

Ore(s): Clay Seams And Altered Areas Of Andesite Tended To Concentrate Secondary Ore
