Luis da Silva and David Reading, CEOs of Afferro and Aureus,
respectively, commented:"This marks the final step in the

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.
