The South Australian Exploration Initiative: Benefits to Government and Industry

Mining has long been an important activity for the people of Australia . The Aboriginals used rocks and minerals in their culture many thousand years before European settlement. It was not until 1840 that silver-lead ore was discovered in the Mount Lofty Ranges , and developed as Australia's first metalliferous mine. The mining industry contributes significantly to all aspects of the Australian economy, generating substantial employment opportunities, investment and income, export earnings and royalties for Governments. While the mining industry in South Australia is small by comparison with Western Australia, Queensland and New South Wales, it is nevertheless a very important industry in the State.   With the discovery of the world's third largest Cu-Au-U-Ag resource at Olympic Dam in 1975, the State saw a period of intense exploration activity through the early to mid-1980s. However, failure to locate additional world class deposits saw a dramatic reduction in exploration activity during the late 1980s. A perceived lack of prospectivity was compounded by the recognition that exploration for such deposits was neither easy nor inexpensive in South Australia because more than 80% of the State is masked by surficial sand and silt.
