Woodstock ProjectElectrolytic Manganese Metal (“EMM”)

Minco Plc

• Woodstock EMM Project located 6 km from the town of Woodstock in west, central New Brunswick, Canada

• Positive Economic Assessment (“PEA”) for production of Electrolytic Manganese Metal (“EMM”)

• Potentially lowest operating costs in the EMM Industry

• Presentation discusses:

• What is EMM?• EMM supply, demand & pricing• Lowest operating costs in EMM industry• Woodstock property acquisition• Woodstock property development plan• Plymouth deposit Inferred Resource• Plymouth deposit mineralogy• Plymouth deposit mining plan• Plymouth site rehabilitation• Hydrometallurgy• Preliminary Economic Assessment• Conclusions

• EMM is primarily consumed in the steel industry as an alloy additive:− 74% of EMM was consumed in the steel sector (42% to the 200 series Stainless Steel sector)

− 12% is used in the production of specialty manganese alloys such as aluminum alloys

− 14% is consumed in electronics and chemical industries

• EMM represents ~9% of the global manganese market

• China currently supplies >95% of world EMM supply

• EMM is produced primarily from manganese carbonate deposits that offer cheaper operating costs over manganese oxide deposits

Woodstock Manganese ProjectLowest Operating Costs in the Industry Minco Plc

• Woodstock Operating costs anticipated to be the lowest in the Industry with production of ~80,000 tonnes of EMM per year over 40 project life:

− US$ 0.68/lb EMM produced over life of project

− US$ 0.64/lb EMM produced in first 20 years

• High Chinese operating costs:

− US$ 0.91/lb EMM produced - average Chinese operating cost

− US$ 0.81/lb EMM produced - lowest Chinese operating cost

• Chinese operating costs anticipated to further increase due to:

− Rising electricity costs

− Rising labour rates

− Declining ore grades for local deposits and high acquisition charges for EMM plants that have to import carbonate ore

− Chinese EMM producers pay a value added tax of 17% plus a 14% import tax into the U.S.

Woodstock Operating costs – US$0.68/lb EMM

Chinese Operating costs – US$0.91/lb EMM

• Identified numerous historic manganese properties, including the Woodstock manganese deposits in New Brunswick

• Acquired a 100% interest in the property in 2010

• Staked additional claims to cover further prospective land covering 58 km2, including the 3 historic deposits

Minco Plc

Woodstock Development Plan:

• Is the historical resource real?

− Log & twin 1986 drill holes to verify results

− Drill an NI 43-101 Inferred Resource over the

Plymouth Deposit

• Hydrometallurgy – Can we produce EMM?

− Conduct bench scale program to design

hydrometallurgical flowsheet

− Produce EMM

• Preliminary Economic Assessment – Can production of EMM be profitable?

− Given that the Chinese dominate production of EMM

with 98% of world production, can we be competitive

and can we produce EMM cheaper than their lowest

cost producer at ~US$0.81 / lb EMM?

Notes:

1. An Mn cut-off value of 3.5% for this resource statement

reflects a reasonable expectation of economic viability for a

deposit of this nature based on market conditions and open

pit mining methods.

2. Mineral resources that are not mineral reserves do not

have demonstrated economic viability.

3. This estimate of mineral resources may be materially

affected by environmental permitting, legal, title, taxation,

sociopolitical, marketing, or other relevant issues.
