Late 1990s

Gold Fields of South Africa decides to sell its base metal assets, including Black Mountain. Anglo American Corporation purchases Black Mountain and the nearby, as yet undeveloped, Gamsberg zinc deposit. Low-key exploration, aimed mainly at finding extensions to the Broken Hill orebody, continues. With the change in ownership almost certainly signaling an end to the drilling program, the chief geologist requests funds for one final hole to test an area remote from those that had already been drilled. This is a turning point in the history of Black Mountain Mining as high-grade mineralization is intersected at a depth of just over 1,000m. Funds are made available immediately for an expanded drilling program.
