Volcanic activity there will produce the gold deposits of the future. Similar investigations have led to the discovery of a Carlin-type gold deposit in Jerritt Canyon, Nevada.Ĭonvergent boundary map: A present-day convergent boundary is located along the Pacific Northwest portion of the United States and extends north along the coast of Canada. ![]() The Carlin mine near Carlin, Nevada, produced gold from a large low-grade deposit that was opened in 1965 after intensive scientific and technical work had been completed. ![]() These may be large enough to be exploited by modern mining and metallurgical techniques. The development of new, highly sensitive, and relatively inexpensive methods of detecting gold, however, has greatly increased the possibility of discovering gold deposits which are too low grade to have been recognized earlier by the prospector using only a gold pan. The lack of outstanding success in spite of the great increase in prospecting during the depression in the 1930's confirms the opinion of those most familiar with the occurrence of gold and the development of gold mining districts is that the best chances of success lie in systematic studies of known productive areas rather than in efforts to discover gold in hitherto unproductive areas.
