MBAC Fertilizer Reports 28% increase in Resources at the Itafós Arraias SSP Project

TORONTO, Jan. 31, 2012 - MBAC Fertilizer Corp. ('MBAC' or the 'Company') is pleased to report the results of an extensional and infill drilling campaign, aimed at testing the north-eastern portion of the Domingos target, located in close proximity to the beneficiation plant at the Itafós Arraias Project. The measured and indicated mineral resource estimate for the project now totals 75.8 million tonnes grading 5.0% P(2)O(5 )up from the previously reported NI 43-101 measured and indicated mineral resource estimate of 58.8 million tonnes grading 5.0% P(2)O(5).

As stated in the April 27(th), 2011 press release, systematic drilling of high-potential areas has led to the identification of additional, shallower and higher than average grade phosphate mineralization in the northern Domingos Block. The new drilling campaign totaled 4,551m of reverse circulation drilling and 768m of diamond drilling.

In addition, MBAC has refined the geological studies and subsequent block modelling for the Canabrava Block. This has led to an increase in the tonnage and grade of the resource at the Canabrava Block as summarized in Table 1 below. No additional drilling is expected to be done at the Canabrava Block during 2012, however the Company believes that further drilling in all directions at the Canabrava Block has the potential to increase the current mineral resource estimate.


2011 Exploration Results

The 2011 drilling campaign targeted the northern extension of the Domingos Block, and was aimed at converting indicated mineral resources into measured mineral resources in an area where the phosphate ore is relatively shallow and located close to the future beneficiation plant site. Infill drilling of the central parts of the Domingos Block has increased the geological confidence and resulted in the conversion of inferred resources into indicated mineral resources. The new drilling has confirmed the Domingos Block as a target along with the São Bento target to the north.

The updated mineral resource estimate has been classified, effective as of December 20, 2011, by Beau Nicholls (BSc (Geo) MAIG), principal consulting geologist for Amazon Geoservices Ltda, who is a qualified person in accordance with National Instrument 43-101. The measured and indicated mineral resource estimate comprises 75.8 million tonnes grading 5.0% P(2)O(5) (using a 1.5% cut-off for the Domingos target and a 2.8% cut-off for all other targets).

Appropriate rounding has been applied to the figures in Table 1 above

Drilling, sampling and QA/QC procedures were established at the beginning of the drilling campaign and conform to acceptable industry standards. QA/QC results have returned acceptable precision and accuracy.

Please refer to the technical report entitled 'Arraias Tocantins Definitive Feasibility Study Report' dated October 26, 2010, as amended February 10, 2011, available under the Company's SEDAR profile at www.sedar.com for further details on the QA/QC procedures.

All recent drilling has been analysed at ALS Chemex Ltd laboratory.


Itafós Arraias Project Update

The Itafós Arraias Project is progressing in accordance with the scheduled timeline. The detailed engineering for the project is almost complete. All equipment on the critical path to construction has been acquired. The earthworks for the project concluded last year and civil construction has commenced at the site, beginning with the water dam. MBAC also has started hiring and training personnel for the day-to-day operation of the SSP plant.

The detailed engineering has shown that the project capital costs have increased in the range of 8-9% due to inflation, but are still in line with the expected accuracy of the feasibility study. The expected capital expenditures for the project are currently fully funded through project finance debt facilities secured by the Company and funds raised through equity financings completed to date. The current average selling price for SSP is currently more than 40% higher than that used in the feasibility study. MBAC expects construction of the project to be complete in Q4 2012 and the commencement of SSP production in the same quarter.
