Slide 8: Mining Industry Reality in a Turbulent World
AGM Presentation June 2008 8 Mining Industry Reality in a Turbulent World • World economic growth dependent upon raw materials • Mining’s 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
Slide 9: Mining Industry & Technology
AGM Presentation June 2008 9 Mining Industry & Technology • Desire to embrace new cost saving technologies will intensify. • Major technology breakthroughs in the last few decades: Exploration: geophysics/remote sensing Mineral processing: gold & copper heap leaching, smelting and HPAL Mining:
Slide 10: New Proprietary Mineral Processing Technology
AGM Presentation June 2008 10 New Proprietary Mineral Processing Technology • Alexander Mining has developed a new and innovative proprietary mineral processing technology called AmmLeach® (patents pending) • Successful pilot plant demonstration of the technology on a high acid consuming copper oxid
Slide 11: MetaLeach owns the intellectual property to two proprietary hydrometallurgical technologies

(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 Hydrom
Slide 14: Background
14 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
Slide 15: Copper extractive metallurgy
15 Copper extractive metallurgy •Global mined copper production is around 17Mtpa ……. ….. Approx. 25% produced using hydrometallurgy and rising. Main process is copper acid leaching and SX-EW of oxides and secondary sulphide ores using sulphuric acid. •Heap and dump leaching dominates as the leaching
Slide 16: Copper heap leach, SX-EW
16 Copper heap leach, SX-EW •Production using leaching recorded in 17/18th 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 1980’s major plants in USA, Mexico and Chile
Slide 17: Zinc extractive metallurgy
17 Zinc extractive metallurgy •Global mined zinc production is around 12.7Mtpa •Most world zinc metal production uses smelting to recover and refine zinc metal from zinc concentrates or zinc oxides. •A new hydrometallurgical process route for zinc oxides has the potential to simplify zinc refining.

Slide 19: Metaleach AmmLeach
Metaleach Ammilaach” AmmLeach’ is a proprietary ammonia based process for the selective leaching and extraction of base metals from high acid consuming or complex ores under ambient temperature and pressure conditions.
Slide 20: No one made it work in ambient heap leach conditions
20 Notable historical use, with mixed results, of ammonia as a leaching agent: • 1916 - Kennecott Copper and Hecla Mining plant to precipitate copper oxide • 1950s - Sherritt Gordon developed a process to recover Ni, Cu & Co from a complex sulphide flotation concentrate using autoclave leaching • 19
Slide 21: Alkaline/ammonia leach process at ambient pressure and temperature
21 AmmLeach® • Alkaline/ammonia leach process at ambient pressure and temperature • Proprietary two stage leaching process – Ore specific cure/pre-treatment stage – Heap or tank leaching • Proprietary solvent extraction step to avoid ammonia carry-over into electrolyte • Uses conventional equipment
Slide 22: AmmLeach - Advantages I
22 AmmLeach® - Advantages I Parameter Acid AmmLeach® Mineralogy Oxides, carbonates, silicates, some Almost any – dependant upon pretreatment sulphides stage Selectivity Low: iron, manganese, calcium and High: no iron, manganese, calcium or silica silica are likely problems dissolution Rate of Limite
Slide 23: AmmLeach - Advantages II
23 AmmLeach® - Advantages II Parameter Acid AmmLeach® Leachant Depends upon carbonate content Depends on concentration used but range consumption but 30 to over 100kg/t ore reported of 3-5kg/t is reasonable for operating heaps Safety Large volumes of concentrated Gaseous ammonia main hazard, acid re
Slide 24: AmmLeach - Potential applications
24 AmmLeach® - Potential applications • Demonstrated at pilot heap scale: Copper from strata-bound carbonate and weathered oxide deposits • Demonstrated at laboratory scale: Zinc from mixed oxide/carbonate/silicate deposits right through to metal Zinc from roaster calcine • Under investigation
Slide 25: AmmLeach - Economics cf. sulphuric acid leaching
25 AmmLeach® - Economics cf. sulphuric acid leaching • Dependent upon mineralogy of the deposit and its location. • Fundamental difference in that whereas acid is consumed by gangue minerals during leaching, ammonia is not, hence for even a moderately high acid consuming ore, ten to fifteen times as
Slide 26: AmmLeach - Economics cf. acid leaching for DRC copper/cobalt oxide ore
26 AmmLeach® - Economics cf. acid leaching for DRC copper/cobalt oxide ore

27 AmmLeach® - Economics cf. acid leaching for DRC copper/cobalt oxide ore
Slide 28: MetaLeach - Focused on commercialisation and revenue generation
28 MetaLeach® - Focused on commercialisation and revenue generation • Dual approach to commercialise the MetaLeach® technologies: – Firstly, third parties to use technology in exchange for a royalty and/or under a licence fee structure, or indeed a minority project interest; – Secondly, by identifyi
Slide 29: Summary
AGM Presentation June 2008 29 Summary • Alexander has developed two proprietary hydrometallurgical ambient temperature and pressure processes. • AmmLeach® has significant economic and environmental benefits cf. acid. • Main AmmLeach® use is for high acid consuming copper, copper/cobalt and zinc oxid
