What is Mining and Milling Practices at Small Gold Mines about?
This paper discusses small-scale lode gold mining and milling. It is abstracted from a bulletin being prepared by the United States Bureau of Mines entitle "Equipping, Developing, and Operating Small Gold Mines." Gold is widely distributed in the mountainous regions of the United States; relatively few deposits, however, can be profitably worked on a large scale. Because of the high intrinsic value of gold, ores containing this metal may be very rich; hence it is possible to mine profitably smaller bodies of gold ore than of the ore common metals
