Cashier Mill is located in Death Valley National Park only a short distance east of Harrisburg, California. The Eureka Mine that fed the mill was opened in 1905 by Shorty Harris and Pete Aguereberry. Pete continued to mine here for 40 years producing $170,000 in gold. His abandoned home and cars still exist at Aguereberry Camp, the only remains of Harrisburg.
The mill was powered by gasoline engines, the mill crushed the oar removed from the nearby mines into powder which was then chemically treated with cyanide and mercury to extract the gold. The mill site and surrounding mines were originally part of Shorty Harris’ claim which he sold to the Cashiers Mining Company. Pete later bought the mill adding to the seven claims he owned in death valley.
The mill’s wood structure still stands but all of the stamps, cams and other pieces have been removed. There is a sealed incline shaft on the hill above the mill.
