Exceptional Partner: Chinalco
Chinalco is world’s 2 [nd] largest
alumina producer & 3 [rd] largest
Chinalco’s 56% holding in YCI
primary aluminum producer
gives it indirect holding of 11.9%
Chinalco 56%
in CYU, the only Chinalco branded
offshore exploration company
Yunnan
Copper
Industry
Group (YCI)
21.3%
Chinalco Yunnan
YCI is China’s 3 [rd] largest Copper Resources
copper producer and essentially (CYU) CYU has led Chinalco
an arm of Chinalco
into Chile for the first time
The relationship provides economically
beneficial projects & a gateway into
potential & future projects
----- End of picture text -----

Most active period in the company’s history:

• Currently drilling major porphyry copper systems in Chile with Rio Tinto

• Second Rio Tinto JV to be drilled IMMEDIATELY following current program

• Currently performing resource calculation AND continuing drilling at our new discovery in the Mt Isa region – 122.7m @ 0.55% Cu, 317 ppm Co. uranium & rare earths

• Currently drilling Zambian style coppersilver projects in Laos with results pending from recently completed programs in Laos – JV operated by Chinalco

• Laos – Chinalco smelters nearby – natural path for monetising discoveries. Projects are advanced & have Chinese resources –

JORC process underway. Potential for rapid development & cash flow using Chinalco infrastructure

• Tier 1 partners: Chinalco Yunnan Copper, Rio Tinto & Xstrata Copper

• Three tier strategy:

Targeting giant porphyry systems in Chile ; building on major discoveries in Mt Isa region; pushing towards development in Laos

Copper Silver – Laos: Chinalco managed, drilling currently, near term cashflow Copper – Chile : Major porphyry systems being drilled

• Mt Isa/Cloncurry Region

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

• Ernest Henry

• We have a discovery

• Thick intersections 100m +

• Copper, gold, cobalt, rare earths & uranium

Suggestive that the 6km untested shear between Mary Kathleen & Elaine is host to multiple deposits

ELAINE/MARY KATHLEEN: 6 KMS OF UNTESTED STRIKE BETWEEN THE TWO

==> picture [564 x 271] intentionally omitted <==

As per Mary K, recent modeling indicates Mary K Shear feeds near horizontal mineralisation – in this copper greater than 0.4% is depicted based on 23 holes drilled so far – main target remains the Mary K Shear with highest grades of copper

• Largest copper mines in the world

• Multi-billion ton operations

• Dominated by world’s top copper companies

• Opportunity for a major discovery

==> picture [244 x 169] intentionally omitted <==

• 2000m diamond drill program is underway at Candelabro

• 60km north is Caramasa to be drilled immediately following 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

• Exceptional large size targets only possible in this region

• Palmani also Rio JV – drilling preparations also underway in coming months

==> picture [233 x 348] intentionally omitted <==

• Humitos 100% CYU-owned claims plus farming into enveloped Xstrata copper property

• CYU/Rio Tinto JV

• Four diamond holes commenced – underway

• • The system has had geological mapping, sampling & geophysical profiles completed to allow drill targeting

• • Significant fieldwork at excellent technical level completed by Rio

FOCUS ON SHORT TERM CASH FLOW

• Development & production options through Yunnan Copper & Chinalco. Chinalco smelters situated in nearby Kunming

• Zambian-style sediment hosted copper silver deposits

• Corporate target 100Mt @ 1% copper & 120g/t silver

• JORC Resource drill outs currently taking place at Xinzhai & Juizhai

• Any resources discovered are of great value given straightforward development pathway

XINZHAI DRILLING:

Hole XZP001 is to test the dipping extension of known mineralisation defined by trenches & adits. Visual copper silver intercepts, assay results due in coming weeks
