RI 4001 Chromiferous Sand Deposits in the Coos nay Area, Coos County, Oreg

During the early part of World War II , it appeared likely that supplies of chromite for United States industry might become critically short . As a part of the ensuing search for new sources of domestic chromite supply , the chromite - bearing black sands along the coast of southern Oregon were hurriedly investigated by State and federal agencies and by private interests , These investigations led to a decision to begin exploitation of the deposits immediately . A government stock- piling program was put into effect , a concentrator was financed by the Defense Plant Corporation , two privately controlled companies were encouraged to start mining operations , and the Bureau of Mines and the Geological Survey were authorized to search. for additional reserves of minable ore .
