Allana Announces Mineral Resource Update: Measured+Indicated Mineral Resources Increase by Over 90%

TORONTO, ONTARIO--(Marketwire - April 30, 2012) -Allana Potash Corp. (TSX:AAA)(OTCQX:ALLRF) ("Allana" or the "Company") is pleased to announce that it has received an updated National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate from ERCOSPLAN Ingenieurgesellschaft Geotechnik und Bergau ("ERCOSPLAN") on its Danakhil Potash Project in Ethiopia.

The measured and indicated mineral resource estimate totals 1,297,529,000 tonnes with an average grade of 19.32 % KCl, representing approximately 250 million tonnes of KCl. This is more than a 90% increase over the June 2011 measured and indicated mineral resource estimate of 673 Million tonnes at an average grade 18.65% KCl, and close to a doubling of the KCl tonnes in these resource categories (see news release dated June 20, 2011)(the "June 2011 report"). In addition to the strong increase in measured and indicated mineral resources, the inferred mineral resource estimate for all four potash units is an additional 588,150,000 tonnes grading 18.56 % KCl. A summary of the mineral resources is presented in Tables 1 and 2 below.

The increase in measured and indicated mineral resources was dominated by an increase of over 170% in the measured category with the revised measured mineral resource totaling approximately 567,815,000 tonnes containing 107,010,000 tonnes of KCl versus 207,620,000 tonnes of measured mineral resource and approximately 36,405,000 tonnes of KCl delineated in the June 2011 report.

The measured and indicated Sylvinite mineral resource specifically increased over 75% to 171,357,000 tonnes with an average grade of 30.93% KCl.

Farhad Abasov, President and CEO, commented: "We are excited to see the large increase in total resources on the project and the significant conversion of inferred mineral resources into measured and indicated mineral resources. The exploration drill campaign over the past 11 months accomplished its twin goals of converting inferred mineral resources to measured and indicated mineral resources and adding significantly to the total project resource base. An over 90% increase in the measured and indicated mineral resource estimate supports management's belief that the Danakhil Depression has the potential to become a world class potash basin. This new expanded resource will form the basis for the Company's Feasibility Study going forward. Exploration drilling will continue on the project to expand the resources and better define the distribution of potash in the basin."

The mineral resource estimate is based on drilling conducted by Allana in 2010-2012 (45 holes) and the historic drill holes completed by the Ralph M. Parsons Company (Parsons) in the 1950s and 1960s. The top of the potash sequence is identified by the Sylvinite Member, followed by the Upper Carnallitite Member (UC), the Bischofitite Member, the Lower Carnallitite Member (LC) and the Kainitite Member.

The measured, indicated and inferred mineral resource estimate was reviewed and optimized by Dr. Sebastiaan van de Klauw, Ph.D., EurGeol., who is a "qualified person" as such term is defined in National Instrument 43-101 and has supervised the preparation of the technical information and data included in this news release. The mineral resource estimates were generated using the parameters set out below.

Drill hole intersections must meet the following criteria for inclusion in the mineral resource estimate:

• Sylvinite Member > 20% KCl, the combined minimum width of Sylvinite and UC Members over 4 metres
• UC Member > 40% Carnallite, the combined minimum width of Sylvinite and UC Members over 4 metres
• LC Member > 60% Carnallite+Kieserite, minimum width of 5 metres
• Kainitite Member > 50% Kainite, minimum width of 5 metres

Allana has drilled 45 holes, all of which provided geological information for the report, but several holes (22, 21, 14, 18, 4) did not meet these criteria and consequently were not included in the resource estimate.

The resource estimates were calculated by extrapolating grades and widths using the Radius of Influence (ROI) from each Allana drill hole and historical drill holes based on industry standards for potash exploration. This process starts with the interpretation of the Radius of Influence of each exploration hole. The following ROIs were used for the calculation of the area of mineralized material in each of the resource categories:

• Sylvinite, Upper Carnallitite Members
  • Measured Resource 350 metres
  • Indicated Resource 750 metres
  • Inferred Resource 1500 metres

• Lower Carnallitite, Kainitite Members
  • Measured Resource 500 metres
  • Indicated Resource 1000 metres
  • Inferred Resource 2000 metres

For historical drill holes a ROI of 750 metres was used for inferred mineral resources in the different members.

The difference in ROI between the two groups is directly related to the geology of the evaporite mineralization. The Sylvinite and UC members are interpreted to be secondary deposits formed from carnallite and therefore not as uniform as a primary evaporite deposit. The Kainitite and LC members are formed by primary evaporite deposition and are relatively consistent throughout the Allana property. Due to this consistency there is a greater degree of confidence in the lateral extent of the mineralization of the Kainitite and LC members and the ROI can be increased.

A copy of the NI 43-101 Technical Report will be available under the Company's profile on SEDAR (www.sedar.com) within 45 days of this news release. The mineral resources were estimated by Dr. Henry Rauche, Ph.D., EurGeol, Managing Director, CEO ERCOSPLAN and Dr. Sebastiaan van de Klauw, Ph.D., EurGeol., Consulting Geologist, ERCOSPLAN. Dr. van de Klauw is the Qualified Person for the purposes of National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators, and has reviewed and verified the data disclosed in this news release.

Activity Update

Exploration drilling continues in the northern part of the property (Holes 50, 51) as part of the program to expand the mineral resources and in-fill gaps in the drilling pattern. Samples from Holes 44-49 are undergoing analysis or are en route to the laboratory in Saskatoon, Canada. Technical studies in support of the Feasibility Study are in progress, including solution mining cavern preparation, solar evaporation pond construction, environmental baseline studies, and hydrogeological studies. Ground geophysical surveys to identify aquifers in the alluvial fans have been completed and data is under evaluation. Mobilization of drilling equipment is ongoing and water well drilling is expected to commence shortly. Procurement of equipment for installation of pilot solution wells in well underway and updated photographs of evaporation pond construction are available to be seen on the company's web-site.
