C. Throughout history, gold has been precious metal, eagerly sought and cherished. It was probably the first metal to be mined because beautiful objects could be made from it — even with primitive tools. The value of gold has always been known, even before gold was used in coinage. It remains the only universally recognized standard of value in international monetary exchange. Most of the world's refined gold is absorbed by governments and central banks to provide backing for paper currency. In addition to its use for jewelry, its special properties have led to many applications in modern science and technology. The largest gold mine is located in South Africa. The largest producing gold mine in United States is the Homestake mine in South Dakota, which yields about 570,000 ounces of gold each year. Often mines throughout the world produce even larger amount of this highly prized metal.
