Section 21E of the Securities Exchange Act of 1934, as amended that are intended to be covered by the safe harbor created by such
sections. Such forward-looking statements include, without limitation, (i) estimates of future molybdenum prices, supply, demand and/or
production; (ii) estimates of future cash costs, direct operating costs, costs applicable to sales (CAS), or royalty payments; (iii) estimates of
future capital expenditures; (iv) estimates regarding timing of permitting, future development, construction or production activities; (v)
statements regarding cost structure, project economics, or competitive position, and (vi) statements comparing Mt. Hope to other mines,
projects, or metals. Where the Company expresses or implies an expectation or belief as to future events or results, such expectation or
belief is expressed in good faith and believed to have a reasonable basis However forward looking statements are subject to risks
basis. However, forward-looking risks,
uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by
such forward-looking statements. These risks and uncertainties include, but are not limited to, metals price and production volatility, global
economic conditions, currency fluctuations, increased production costs and variances in ore grade or recovery rates from those assumed in
mining plans, exploration risks and results, political, operational and project development risks, including the Company’s ability to obtain
required permits to commence production and its ability to meet conditions precedent required to complete the Hanlong financing, adverse
g
governmental regulation and j
g judicial outcomes. For a more detailed discussion of such risks and other factors, see the Company’s Annual
p y
Report on Form 10K, which is on file with the Securities and Exchange Commission, as well as the Company’s other SEC filings. The

Cautionary Note to U.S. Investors Concerning Estimates of Reserves and Resources
Calculations with respect to "proven reserves" and "probable reserves" referred to above have been made in accordance with, and using
the definitions of National Instrument 43-101, as required by Canadian securities regulatory authorities. For United States reporting
purposes, the U.S. SEC applies a different standard in order to classify mineralization as a "reserve". Under SEC standards, mineralization
may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally
extracted or produced at the time the reserve determination is made. No such determinations have been made with respect to any
mineralization at the Liberty project, and it cannot be assured that such a determination will be made. This release also uses the terms
“measured”, “indicated” and “inferred” resources We caution U.S. investors that while such terms are recognized and required by
measured indicated inferred resources. US
Canadian Securities Administrators pursuant to the National Instrument 43-101, the SEC does not recognize them. U.S. investors are
cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. “Inferred
Resources”, in particular, have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal
feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under
Canadian Securities Administration rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility
studies. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally minable.

9. Molybdenum Overview
• Essential metal for modern industry
• Industrial requirements demand better steels
q
• Strengthens steel, improves weldability, reduces brittleness, helps steel
perform in very high or very low temperatures
• Applications for energy, pipeline development, nuclear power plants,
desalination, refineries, catalyst for high sulphur fuels, motor vehicles
• Powerful anti-corrosive alloy for stainless and alloy steels
anti corrosive
• Molybdenum is vital in the products in which it is used with few
substitutes
• Moly demand is relatively price inelastic
9

10. Moly Demand Growth Projected to be Robust
• Moly demand to grow +30M lbs per year or approximately 128M lbs by
year,
2015 when Mt. Hope projected to be in full production.
• Moly use recovered and grew 18% in 2010 and 13% in 2011 (IMOA)
• Demand forecast to grow 5.5% CAGR through 2020 to reach over 800
million pounds annually
• Supported by global steel demand growth (~3.5% CAGR) and growing
intensity of use

• More sophisticated energy
production and transportation
driving moly use
• Examples include:
• Shale Gas Production
• Off-shore / deep-ocean oil production
• LNG development

to be spent globally on energy
energy-
supply infrastructure by 2035
• JP Morgan says Mo one of 5 key
commodities for 21st century1 Source: SMR Research
