Cargo Mining Claim - Imperial County, California

The Cargo Mine is located in the low western hills of the Cargo Muchacho Mountains. The gold in the Cargo Muchacho mountains is well known and has a long history. The Cargo Mine is one of the first deposits mined in Imperial County. The deposit was located in 1877 by Thomas Porter Neet, and by 1882, 14,000 tons of ore had been mined which averaged $12 per ton. The mine was surveyed for patent in 1892. Other periods of major activity were 1890-1894 and 1936- 1942, 1949-1952. Total production probably exceeds 25,700 ounces of gold. The mine is developed by a 680-foot inclined shaft at the north end of the vein, and a 200-foot vertical shaft about 1100 feet south of the deep shaft. Most of the stopes are below the third level. The area as far north as 800 feet of the main shaft was explored on the surface by several shallow shafts. In another prospect a 125-foot adit was driven due north from a point 1000 feet N 70 degrees W of the main shaft.
