VANCOUVER, BRITISH COLUMBIA--(Marketwire -07/11/12)- Alderon Iron Ore Corp. (ADV.TO)(AXX)(AXX) ("Alderon" or the "Company") is pleased to announce the results of the final mineral resource estimate on its Kamistiatusset ("Kami") Iron Ore Project in western Labrador. The estimate includes a Measured and Indicated mineral resource of 1.1 billion tonnes at 29.8% iron and an Inferred mineral resource of 277.4 million tonnes at 29.5% iron (refer to tables below for tonnage and grade details) based on a cut-off grade of 20% iron.

"We are extremely pleased with this final resource estimate for Kami," says Tayfun Eldem, President and CEO of Alderon. "The completion of each successive drill program has resulted in an increase in the mineral resource estimate, while continuing to confirm consistent grades. The final numbers clearly underline the potential and the value of the Kami Project. The Measured and Indicated mineral resources will form the basis for Kami's Feasibility Study that is expected to be completed before the end of this year."

Resource Estimate Details

The mineral resource estimate for the Kami Project is based on results from 209 diamond drill holes at Rose Central and North Rose (170 holes) and Mills Lake (39 holes) zones totaling 62,247 m and is effective as of July 11, 2012. Watts, Griffis and McOuat Limited ("WGM"), Consulting Geologists and Engineers of Toronto, Canada, was retained to audit an in-house estimate completed by Alderon. Mr. Michael Kociumbas, P.Geo., and Mr. Richard Risto, P.Geo., with independent firm, WGM, are Qualified Persons as defined by NI 43-101 and are responsible for reviewing and approving this mineral resource estimate. They have verified, reviewed and approved the technical data contained in this news release and underlying sampling, analytical and test data. WGM has previously visited the site, collected independent core samples and reviewed the QA/QC data received to date. Mr. Risto has reviewed and approved the underlying sampling, analytical and test data used for the Estimate. The estimate is classified as a Measured, Indicated or Inferred mineral resource, consistent with the CIM definitions referred to in National Instrument (NI) 43-101. Alderon is not aware of any environmental, permitting, legal, title, taxation, socio-political, marketing or other issues which may materially affect its estimate of mineral resources.

The geological and mineral resource modelling parameters consisted of:

 

-- Creation of 3-D wireframes from the drillhole intersects using assay
intervals and major lithological units.

-- A block model procedure (block sizes of 15 m x 15 m x 14 m for Rose
Central and Rose North and 5 m x 20 m x 5 m for Mills Lake) was used
with grades interpolated utilizing an Inverse Distance estimation
technique; Total Iron (TFe%), Fe in magnetite, Fe in hematite,
Manganese% and SiO2% were modelled.

-- A variable density model was used based on best fit regression line from
all DGI (downhole physical properties probe) measurements, therefore
each block in the block model has unique specific gravity and gives a
more representative tonnage based on Fe grades.

Complete assay results are posted on the Alderon website at http://www.alderonironore.com/_resources/kami/2010-2012_Kami_Drill_Results.pdf.

Three dimensional images showing the outline of the mineral resources are posted on the Alderon website at http://alderonironore.com/projects/kami/.

Sawn drill core samples were sent to SGS Mineral Services in Lakefield, Ontario for analyses. Total iron analysis was performed using X-ray fluorescence and the magnetic component was determined by Satmagan magnetic analysis. Standards, blanks, and duplicate assays were included at regular intervals in each sample batch submitted from the field as part of an ongoing Quality Assurance/Quality Control program.

Cautionary Note Concerning Reserve and Resource Estimates

This press 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 press 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.
