4. Woodstock Project
Electrolytic 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

5. • 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

8. Woodstock Manganese Project
Lowest 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

9. • 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

10. Woodstock Manganese
Development Plan
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.
