  • AGM Presentation June 2008 Mining Basics - Theory Turnings rock in the ground into profits! Or more eloquently The fundamental value of a mineral deposit ultimately depends entirely on its capacity to support an economically viable mining operation in the future 5

  • AGM Presentation June 2008 The best route to create shareholder value? 1.Through exploration? 2.Mine development? 3.Project acquisition? 4.Corporate M&A? 6 A combination?

  • AGM Presentation June 2008 A Risky Business in a Risky World Macro risks: Country, commodity price, global economics Micro risks: from exploration concept to mine production: Exploration tenement acquisition, target concept, reconnaissance, anomalies, targets, detailed exploration, discovery, resource delineation/definition Project scoping study, pre-feasibility, bankable feasibility study, permitting, financing, construction, commissioning Mining technical, geotechnical, economics 7

  • AGM Presentation June 2008 Mining Industry Reality Statistically its a tough business and getting harder Out of thousands of grass roots exploration prospects only a few ever make it to become mines with a satisfactory return on capital Constant pressure on the industry to improve the odds of success and to lower costs Environmental obligations for higher standards Notwithstanding industrys inherent conservatism, technology has a significant role 8
  • Slide 9
  • AGM Presentation June 2008 Mining Industry & Technology Buoyant international mining industry, plus upwards operating cost pressures, means desire to embrace new technologies will intensify. Major technology breakthroughs in the last few decades: Exploration (geophysics/remote sensing), Mineral processing (gold & copper heap leaching, smelting and HPAL) and Mining (explosives, underground mechanisation, open pit excavators and haulage trucks, and computer control). Deposits are becoming harder to find and mine more underground mines Arguably, most potential for technical innovation is in mineral processing. 9

(Hons) in Minerals Engineering, University of Leeds, Ph.D. Royal School of Mines, Imperial College, London 8 years as researcher at Australian National University 6 years, Senior Lecturer in Hydrometallurgy at Murdoch University Currently, Xstrata Zinc Alliance Associate Professor at University of Ballarat Two edited proceedings, >70 journal papers, R. W. Raymond Award for best paper published by AIME in 2003 plenary conference Over 30 conference presentations and Editor-in-Chief of the journal Hydrometallurgy
  • Slide 19
  • 19 Background Favourable environment to embrace new technologies. Focused on hydrometallurgical solutions that add value at the mine site. Cost effective ambient whole ore leaching process using either agitated tanks or heaps. Conventional and marketable intermediate products Purification and concentration using SX-EW.
  • Slide 20
  • 20 Copper extractive metallurgy Global mined copper production is around 16.5Mtpa . .. Approx. a quarter produced using hydrometallurgy and rising. Main process is copper acid leaching and SX-EW of oxides and secondary sulphide ores but acid prices have risen sharply. Heap and dump leaching dominates as the leaching process. Chalcopyrite (CuFeS 2 ) concentrates are invariably smelted and account for around three-quarters of global copper produced
  • Slide 21
  • 21 Copper heap leach, SX-EW Production using leaching recorded in 17/18 th century at Rio Tinto mine in southern Spain First commercial leach SX-EW plant started in late 1960 s in Arizona @ 6ktpa First large plant in 1973 in Zambia @ 100ktpa By 1980s major plants in USA, Mexico and Chile Now accounts for ~ 3.5Mtpa (~21%) of world copper production
