    South Africa. Gold Records There are two major hypotheses for the origin of gold within the Witwater- srand basin—the "placer" model and the "hydrothermal" model. Both con- cepts date back more than 100 years, and each has traded places several times with the other as the favorite among scientists. Determining which of these theories is correct not only con- cerns earth scientists who wish

    Methods of Gold Mining Geology In. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers

There is a need to summarize such information and, more importantly, to attempt to synthesize it into a coherent classifica-tion of gold deposits. The purpose of this paper therefore is to present a summary of the

The government order restricting gold mining in the United States during the war resulted in a precipitous drop in annual production to less than 50 metric tons. After the war, a brief increase in annual production tailed off into a gradually declining

    An example can be seen in the successful search for gold deposits in the South Pacific. There, exploration models have been based on principles developed in the study of modern geothermal systems. Giant deposits such as Lihir and Porgera have been the reward. Another example is the giant copper-gold-uranium deposit at Olympic Dam, South Australia, discovered beneath 300 m of cover
