3 Elements to the Roseby ProjectLittle Eva: A Development Ready ProjectFully permitted with DFS completed on a simple39,000tpa (86mlbs pa) copper open pit mine andflotation plant.Major Resource Inventory1.52Mt copper metal including 0.84Mt (1,850mlbs)copper in 7 ‘native copper’ deposits outside Little EvaProject.Exploration1,500km² of exploration tenure prospective for copper,gold, molybdenum, uranium and zinc-lead-silver.altonamining.com April 201310.

Little Eva is a Large Deposit• 1.3km long, 20-370m wide• Drilled up to 300m deep (511drillholes, 76km)• Large bulk IOCG style deposit similarto Ernest Henry• Strip ratio of 1.8:1 after 15Mt pre-strip• Little Eva deposit reserve: 53Mt ore at0.6% copper, 0.1g/t gold.• Additional 6Mt reserves in 3 smallsatellite pits• 15Mt of low grade ore stockpiled andtreated at end of mine life• 11 year mine life• Underground potentialaltonamining.com April 201311.

Can Roseby be bigger than 2Mt copper?• Altona has grown resource 60% to1.52Mt of copper metal in 2 years• 4 Reserves, 7 Resources and manyprospects and workings• Little systematic exploration for 15years• Turkey Creek discovery in August2012 highlights prospectivity• All deposits open and growing, manytargets for extensions• Dugald River zinc and Mary Kathleenuranium highlight that explorationpotential not limited to copperPlan of depositsand prospects atcentral Rosebyareaaltonamining.com April 201316.

Companion: Example of Exploration Target• Several parallel zones ofmineralised outcrop and artisanalworkings 25km south of Little Eva• Total strike ~7km, individual zonesup to 1km long and up to 30m inwidth• Potential for additional 4km alongstrike to south (work in progress)• Outcrop samples up to severalpercent copper and several gramsper tonnes gold, visible gold atsurface• Only 4 historic drill holes in thearea (best 7.5m at 0.9% copper)• Systematic RAB drilling underwayaltonamining.com April 201317.

Fourpart Strategy for Roseby1. Finance: Conclude financing /partnering negotiations in mid20132. Produce: Build a stand alone~7Mtpa copper concentrator atLittle Eva sulphide ore from LittleEva open pit and 3 satellites3. Expand: Develop ‘native copper’deposits for additional 10-15ktpacopper4. Explore: Target 2Mt coppermetal resource. Initial focus onsulphide ore to supply Little Evaconcentrator eg. Turkey CreekOld copper workings at Lady Clayrealtonamining.com April 201318.
