In an effort to exploit the barite deposit, Food Machinery Corporation (FMC) leased the claims from the BLM in late 1947 and by 1951, began active mining of the Mountain Springs deposit. The high-grade barite ore was mined by conventional means and shipped to FMC's Modesto, California facility for final processing and packaging. FMC actively ...

The drinking water in the mining region had sulphate concentrations that ranged from 211 to 589 mg/L, compared to sulphate concentrations of 25 mg/L or less in the non-mined areas. The natural existence of barite and the widespread mine waste dumps at Mangampeta are believed to be responsible for the higher levels of sulphate in the ground water.
