As a result of the Arrangement, each shareholder of African Aura received one new common share of African Aura and one common share of Aureus Mining for each common share of African Aura held by such shareholder at the Effective Time. In addition, African Aura has now changed its name to "Afferro Mining Inc." as part of the Arrangement and all further press releases of African Aura will be issued under the name of "Afferro Mining Inc." ("Afferro Mining"). Afferro Mining's new website effective today is www.afferro-mining.com.

Following the completion of the Arrangement, the common shares of Afferro Mining have today been admitted to trading on the AIM market of the London Stock Exchange and will be listed on the TSX Venture Exchange (the "TSXV"), in each case under the stock symbol "AFF".

Luis da Silva and David Reading, CEOs of Afferro and Aureus, respectively, commented:

"This marks the final step in the restructuring of African Aura on its path to unlock the latent value in the combined group. The IPO of Aureus creates two attractive and robust pure commodity plays well positioned for growth in the immediate future. With two strong executive and management teams and solid technical experience, both are companies ready for progress as independent entities."

Forward-Looking Information

This press release contains certain forward-looking information. All information, other than information regarding historical fact, that addresses activities, events or developments that Afferro Mining and/or Aureus Mining believe, expect or anticipate will or may occur in the future is forward-looking information. Forward-looking information contained in this press release includes, but may not be limited to, the future plans and objectives of Afferro Mining and Aureus Mining and their anticipated future growth, the admission and listing of the common shares of each of Afferro Mining and Aureus Mining as set forth above, mineral resource estimates, the anticipated exploration and development activities of each of Afferro Mining and Aureus Mining (including the resource expansion drilling programme at the Nkout Project and surrounding iron projects in Cameroon and the projected targets relating thereto). The foregoing and any other forward-looking information contained in this press release reflects the current expectations, assumptions or beliefs of Afferro Mining and/or Aureus Mining based on information currently available to Afferro Mining and/or Aureus Mining. With respect to the forward-looking information contained in this press release, Afferro Mining and Aureus Mining have made assumptions regarding, among other things: general business, economic and mining industry conditions; and it has also been assumed that no material adverse change in the price of precious and/or base metals occurs, no unusual geological or technical problems occur and no significant events occur outside of the normal course of Afferro Mining's or Aureus Mining's respective businesses.

Such forward-looking information is subject to a number of risks and uncertainties that may cause actual results or events to differ materially from current expectations, including: risks normally incidental to exploration and development of mineral properties; uncertainties in the interpretation of results from drilling and test work; the possibility that future exploration, development or mining results will not be consistent with expectations; uncertainty of mineral resources estimates; adverse changes in precious and/or base metal prices; and future unforeseen liabilities and other factors including, but not limited to, those listed under "Risk Factors" in the Information Circular of African Aura dated February 28, 2011, a copy of which is available on SEDAR at www.sedar.com, and in the Aureus Mining Admission Document, a copy of which is available at www.aureus-mining.com.

Any mineral resource figures referred to in this press release are estimates and no assurances can be given that the indicated levels of minerals will be produced. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While Afferro Mining and Aureus Mining believe that the mineral resource estimates in respect of their respective properties are well established, by their nature mineral resource estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. If such mineral resource estimates are inaccurate or are reduced in the future, this could have a material adverse impact on Afferro Mining and/or Aureus Mining, as applicable. Due to the uncertainty that may be attached to inferred mineral resources, it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration.

Forward-looking information speaks only as of the date on which it is made and, except as may be required by applicable law, Afferro Mining and Aureus Mining disclaim any obligation to update or modify such forward-looking information, either as a result of new information, future events or for any other reason.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accept responsibility for the adequacy or accuracy of this release.
