Most active period in the company’s history:

• Currently drilling major porphyry copper systems in Chile with Rio Tinto. Exciting discovery hole VISUAL copper >100m.

• Rig moving to 2[nd] Rio JV while assays are awaited – 6 weeks. Potential major porphyry system. Outstanding Rio projects acquired due to strong in country relationships.

• Mt Isa Discovery: Currently performing resource calculation and continuing drilling - Continuous gold and copper mineralisation and major rare earth discovery 26m @ 1.7g/t Au, 0.24% Bi, 213 ppm Co, 0.27% Cu. Uranium and Rare earths.

• Laos – Drilling Zambian style copper-silver prospects. Chinalco smelters nearby – natural path for monetising discoveries. Projects are advanced and have Chinese resources – JORC process underway - Potential for rapid development and cash flow utilising Chinalco infrastructure:

• World Class partners: Chinalco Yunnan Copper, Rio Tinto and Xstrata Copper

Three Tiered Strategy:

1. Targeting Giant porphyry Systems in Chile

2. Building on Major discoveries in the Mt Isa region

3. Pushing towards development in Laos

Copper Silver - Laos: Chinalco managed, drilling currently, near term cashflow Copper – Chile : Major porphyry systems being drilled Copper – Queensland: Managing Elaine drill out and further discoveries

• Mt Isa/Cloncurry Region.

• Home to some of the biggest discoveries in Australian mining history.

• We have a discovery. Resource calc underway

• • Thick intersections: MKED009

• 109 metres @ 1.98 g/t Gold, 0.50% Copper, 482ppm Cobalt

• 26m @ 7.76 g/t Gold within this intersection.

• Recent shallow gold hit with bismuth: MKED026

• 26m @ 1.7g/t Gold, 0.24% Bismuth, 213 ppm Cobalt, 0.27% Copper. Uranium and Rare earths. Including 9m @ 3.63 g/t Gold.

• Copper, gold, cobalt, rare earths, thorium and uranium present in this project. Forms part of a rich mineral province.

Elaine 1. 109m @ 0.5% Cu 482ppm Co 1.98 g/t Au. Resource calc underway. Potential multiple trap sites along the shear zone.

• MKED32 currently drilling Elaine 1.

• Elaine 1: Additional results pending on 3 diamond holes already completed.

• Elaine 2 and 3. Results awaited on 2 diamond holes

• These are outside the current resource envelope, so any discoveries will add to the inventory

• Hole MKED26 results released yesterday also not included in current resource calculations

• Rig moving upon completion to Cloncurry North to test deep IOCG Ernest Henry style targets. Significant geophysical anomalies as part of the Yunnan Exploration JV. Fully Funded by YEX – $5m over three years. Great partnership for a junior!

• Field work simultaneously at Xstrata Copper JV at Mt Frosty on the same shear zone to generate drill targets to drill on completion of the Cloncurry North Program

• Largest copper mines in the world

• Multi-billion ton operations > Olympic Dam

• Dominated by the worlds top copper companies

• Opportunity for a major discovery: awaiting assays on major visual intersection with Rio Tinto JV. Watch this space

• 2000m diamond drill program is underway at Candelabro. Results out last week Visual copper over 125m. Assays pending. Potential major porphyry system.

• 60km North is Caramasa which is to be drilled immediately while assays are awaited at Candelabro.

• Adjacent to Peruvian border. Major structures run into Peru. Chile better jurisdiction.

• Caramasa – RIO JV seeking major multi-porphyry systems. Major system targeting major resources.

• How did this Opportunity arise? Chinalco relationship. Previous working relationship with Rio Tinto.

• Exceptional large size targets only possible in this region with major partners. We have 3 of these major projects.

• Palmani also Rio JV – drilling preparations also underway for the coming months

CYU and Rio Tinto JV

• Final drill hole underway, image from ASX release 5[th] June visual sulphides below.

• 7 holes vectoring to centre of system after each hole is analysed.

• Final hole underway and Assays pending
