Part of the Alladin Group
Alteration: Silificion

Deposit: Tactite body at contact of granite porphyry with limestone also, some gold-bearing quartz veins. The delmas copper co., owner of several claims, developed their property by means of shallow pits and adits to explore the copper ore deposits in the tactite body which extends in a zone over 2000' long, and 125'-400' wide. Much of the early development was completed from 1906-1908. This activity resulted in the shipping of ore to the utah smelters. The sweepstakes claim is the most extensively explored. Ore shipped ran As high As 70 oz. Of silver, 10.4% copper, and 2.8% lead. The highest grade ore carries chalcocite coated sulphides ; info.src : 1 pub lit

Deposit type: Skarn Cu

Development: Early development took place 1906 to 1908, when ore was shipped to utah smelters

Geology: Some gold-bearing quartz veins occur in the granite porphyry

Ore(s): Intrusive Contact, Favorable Rocks
