In early 2001, Newmont acquired Battle Mountain Gold Co. and in 2002 Normandy Mining, so further extending its gold mining and exploration base in Nevada. In 2002, Newmont owned or controlled 7,915km of land along Interstate 80. Mining started with open pits, some of which have been extended underground since 1994.
Even today, however, some gold seekers will use the light and simple pans for prospecting, systematically sampling gravels as they work up a stream, for example, and knowing that when the gold “color” stops, a vein or two of gold feeding into the stream may be close at hand.

Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide and toxic.
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe.
