The World Gold Council on Grading

The World Gold Council defines a high-quality underground mine as having a gold ore density between 8 and 10 g/t, while a low-quality underground mine has a gold ore density of 1 to 4 g/t.5 Open-pit mines tend to have a lower grade, but they can be considered very valuable because of the lower average operating costs necessary to obtain them. 11 The council recommends using cost per ounce, not gold ore grading, to evaluate a gold mine.

Using the World Gold Council's g/t standard, many of the world's high-grade gold mines are in the United States, Russian, and Peru. The Fire Creek mine in Battle Mountain, Nev., for example, was reported to have one of the highest at 44.1 g/t. Others making the list include the Macassa mine in Canada, the Kedrovka mine in Russia, and the Toguraci mine in Indonesia.6
