Alderon Files Combined Technical Report for Kami Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 21, 2012) - Alderon Iron Ore Corp. (TSX:ADV)(NYSE Amex:AXX) ("Alderon" or the "Company") announces that it has filed on SEDAR, at www.sedar.com, a Technical Report entitled "Technical Report Preliminary Economic Assessment of the Rose Central Deposit and Resource Estimate for the Rose Central, Rose North and Mills Deposits of the Kamistiatusset (Kami) Iron Ore Property, Labrador for Alderon Iron Ore Corp." dated effective October 26, 2011 (the "Combined Report") in accordance with National Instrument 43-101.

Alderon previously filed a Technical Report dated September 8, 2011, presenting a Preliminary Economic Assessment for the development of the Rose Central Deposit of the Kami Property and a Technical Report dated October 26, 2011, presenting a Mineral Resource estimate for the Rose North Deposit of the Kami Property (the "Prior Reports"). This Combined Report comprises a consolidation of the two aforementioned Prior Reports and supersedes the Prior Reports. The Combined Report does not contain any new material information that was not included in the Prior Reports. Only the Combined Report should be relied on as the current technical report on the Kami Property.

Kami Property Summary

Kami Property Mineral Resource Estimate

The Rose Central Deposit, together with Mills Lake Deposit and North Rose Deposit of the Kami Property, have an Indicated Mineral Resource estimate of 490 million tonnes at 30.0% iron and an additional Inferred Mineral Resource estimate of 598 million tonnes at 30.3% iron at a cut-off grade of 20%. The effective date of the Mineral Resource estimate is October 26, 2011. Mineral resources that are not mineral reserves do not have demonstrated economic viability

Preliminary Economic Assessment of the Rose Central Deposit

The results of the Preliminary Economic Assessment ("PEA") of the Rose Central Deposit of the Kami Property set out below are unchanged from those announced in Alderon's September 8, 2011 news release. The PEA is based only on the development of the Rose Central Deposit of the Kami Property. Highlights of the PEA include:

• Concentrate production rate of 8 million tonnes per year at a grade of 65.5% iron.
• Subject to certain risks and uncertainties set forth below, commercial production is expected to commence in Q4 2015 with a mine life of 15.3 years.
• Capital cost of US$989 million (excluding closure costs, sustaining capital & leased equipment).
• Pre-Tax IRR of 40.2%.
• Pre-Tax NPV (discounted at 8%) of US$3.07 billion.
• Payback period of 2.7 years.
• Total operating cost (excluding royalties) of US$44.87/tonne concentrate (averaged over the life of mine).

The PEA is preliminary in nature and it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Total capital expenditures (including contingency) are estimated at US$988.9 million. The capital cost estimate excludes closure costs and sustaining capital, which are expected to be approximately US$25.4 million and US$198.4 million, respectively for the life of the project.

The PEA assumes a concentrate selling price of US$115/tonne for the life of the project and includes a 3% gross sales royalty on iron ore concentrate to Altius. Total operating costs, including annual costs for leasing of equipment (valued at US$259.2 million) over the life of the leases, are estimated at US$44.87/tonne of concentrate.

Alderon has not yet completed a Pre-Feasibility Study or Feasibility Study to demonstrate the economic viability of the Kami Property. Furthermore, no Mineral Reserves have been established on the Kami Property. Any statements regarding planned production rates, projected cash flows, payback period, IRR, NPV, construction timelines or the expected commencement of commercial production in Q4 2015 assume that Alderon is or will be able to complete all of the required steps to bring the Kami Property into commercial production including the completion of a Feasibility Study to demonstrate the economic viability of the Kami Property, the completion of the environmental assessment process, the conclusion of infrastructure agreements for railway transportation, power and access to port facilities and that Alderon obtains the necessary project financing to pay for the capital costs to develop and construct a mine at the Kami Property. There is no certainty that Alderon will be able to complete any or all of these steps and reference should be made to the "Risk Factors" section in Alderon's Annual Information Form for the most recently completed financial year.

Future Exploration and Development

Alderon is currently conducting its 2012 winter drilling program on the Kami Property. The four month drill program will be focused predominately on the North Rose Deposit and will include up to 18,000 metres of drilling with six drills. The program will concentrate on infill drilling with the goal of upgrading the current mineral resource estimate from the indicated and inferred categories to the measured and indicated categories in preparation for the Feasibility Study on the Kami Property expected to be completed in the third quarter of 2012.

Cautionary Note Concerning Reserve and Resource Estimates

This news release uses the terms "reserves", "resources", "proven reserves", "probable reserves", "measured resources", "indicated resources" and "inferred resources". United States investors are advised that, while such terms are recognized and required by Canadian securities laws, the United States Securities and Exchange Commission (the "SEC") does not recognize them. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Mineral resources that are not mineral reserves do not have demonstrated economic viability. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Inferred Resources are in addition to Measured and Indicated Resources. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can be mined legally or economically. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations, however, the SEC normally only permits issuers to report "resources" as in place tonnage and grade without reference to unit measures. Accordingly, information concerning descriptions of mineralization and resources contained in this release may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the SEC.

National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all reserve and resource estimates referred to in this news release or released by the Company in the future have been or will be prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Classification System. The requirements of NI 43-101 are not the same as those of the SEC and any reserves reported by the Company in compliance with NI 43-101 may not qualify as reserves under the SEC's standards.
