MBAC files Amended Technical Report for Araxá Phosphate/REO/Niobium project in South East Brazil

TORONTO, Feb. 3, 2012 - MBAC Fertilizer Corp. ('MBAC' or the 'Company') announces that it has amended the National Instrument 43-101 Technical Report filed on January 16, 2012 (the 'Amended Technical Report') regarding its Araxá Phosphate/REO/Niobium project (the 'Araxá Project') located in the southern part of the State of Minas Gerais, Brazil to reflect adjustments made to the current inferred mineral resource estimate for the project, as detailed below.

MBAC is continuing exploration of the deposit at Araxá and anticipates completing a preliminary economic assessment (the 'PEA'), which will include an updated mineral resource estimate based on the full suite of rare earth elements, in Q2 2012.

Antenor Silva, Vice Chairman and CEO stated 'We continue to be very excited about prospects for the Araxá Project. The amended inferred mineral resource estimate is based on only three out of the 15 rare earth elements that we believe are present at the deposit. We continue to advance work on the property, having drilled over 2,000 metres to date, to gain greater confidence in the composition of the deposit including overall grades and size of the deposit as well as a breakout of the separate rare earth elements. Our plans with respect to this project remain on schedule and we expect to complete the PEA during the second quarter of 2012.'


Summary of Amendments to Araxá Technical Report

The inferred mineral resource estimate previously considered a factor of 1.27 over the CeO(2), La(2)O(3) and Y(2)O(3) to calculate the Total Rare Earth Oxide ('TREO'). The factor of 1.27 was based on work carried out by Extramil, the previous owner of the deposit. Based on this historical work, a factor of 1.27 x sum (CeO(2) + La(2)O(3) +Y(2)O(3)) = TREO was calculated based on a set of bulk sample results using the full suite of rare element oxide ('REO') data.

The amended inferred mineral resources estimate now considers only the grades of CeO(2) + La(2)O(3) +Y(2)O(3) (plus Niobium and Phosphate) for which full assays have been completed, and excludes any analysis of TREO and the use of the above-noted factor. The remaining TREO is currently being treated by MBAC as an exploration target only and the 1.27 factor is being used for the exploration target area only.

The following table summarizes the amended inferred mineral resource estimate which is based on Cerium-Lanthanum-Yttrium Rare Earth Oxide ('CLYREO') only. A cut-off grade of 6% CLYREO has been used for the amended inferred mineral resource estimate, as summarized below, based on (CeO(2) + La(2)O(3) +Y(2)O(3)) multiplied by 1.27:

Continued Exploration at Araxá

MBAC is continuing its exploration of the deposit and is currently conducting additional drilling aimed at defining an updated mineral resource estimate reflecting increased mineral resource confidence in the measured and indicated categories, which will be based on the full suite of REO including the remaining TREO that is currently being treated as an exploration target only. The Company also continues to work on the optimization of the metallurgy. Several samples have been collected and the process route will be tested for samples from the other areas within the target region. The PEA is underway and is being prepared by a qualified independent third party with expertise in the rare earth sector.


Qualified Person

Beau Nicholls, (MAIG) principal consulting geologist of Amazon Geoservices Ltda, is the qualified person responsible for the technical information in this press release. The exploration data is historical but Amazon Geoservices Ltda has completed a site visit and validated the drillhole positions and geology in the field and has reviewed the diamond core which has been stored in Belo Horizonte. Due diligence grab samples have been taken in the field by Amazon Geoservices Ltda and a re-sampling umpire program for the available diamond drillholes is in process and will be submitted to international laboratories based on appropriate QA/QC procedures.
