Worldwide nonferrous metals exploration activities had changed drastically in 1990s. From early 1990s to 1997, the exploration budget steadily increased due to the high metals prices and privatization of mining sector in developing countries. However, the drop in metals prices in 1997 caused to fall the exploration budget, and this downturn continued until 2002. Here, 14 base metal companies are focused and their detailed exploration activities are clarified from late 1990s to 2003.
