TRADING SYMBOL:  TSXV  EPO.V

VANCOUVER, March 18 /CNW/ - Encanto Potash Corp. ("Encanto" or the "Company") is pleased to release the results of the NI 43-101 Technical Report prepared by North Rim Exploration Ltd. ("North Rim") of Saskatoon, Saskatchewan on the Company's Muskowekwan project situated on the Muskowekwan First Nation ("MFN") Home Reserve (16,831 acres) in Saskatchewan.  At the Company's request, North Rim has prepared resource calculations based on both the solution mining extraction method and on the conventional mining extraction method.  Encanto decided to evaluate and report the two resource calculations in order to determine, at a later date in future engineering studies, the most economically viable method for extraction. These resources are restricted to the Home Reserve only and do not take into account the Treaty Land Entitlement ("TLE") Reserve lands (15,500 acres contiguous to the Home Reserve) whose mineral resources and lands are owned by MFN and are included in our Joint Venture agreements with MFN and Exploration Permits from Indian and Northern Affairs Canada("INAC").  The TLE Reserve lands and minerals are currently undergoing a designation process to surrender the mineral rights to Canada, these rights are then returned back to MFN.  Once the TLE lands are designated, North Rim will recalculate to include those resources in an amended NI 43-101 Technical Report and has the potential of adding up to15,500 acres, or 90% to the resource area.  Encanto's completed 2D and 3D seismic program was conducted on both the MFN Home Reserve and on the TLE Reserve lands. 

North Rim has extensive experience in the resource characterization and preparation of NI 43-101 Technical Reports on potash resources having worked on Saskatchewan potash projects for Mosaic, Potash One, Athabasca Potash and Karnalyte Resources.

The reader is cautioned that the 2 mining scenarios presented below should be treated as separate mineral resource calculations and should NOT be added together. The solution mining scenario was prepared as the base case with the conventional resource provided as a sensitivity case until additional engineering studies are completed.  Engineering factors that are yet to be determined to assess the economic viability may be, but are not limited to:

• Study of the geothermal gradient to determine the energy inputs required (solution mining scenario).
• Study of potential engineering challenges to determine suitable pillar sizes and extraction ratios (conventional mining scenario).
• The "recoverable K₂O" resource may change due to the uncertainty of the mining method at this time.  Additional work on economic viability may be necessary.

The resource for the potential solution mining intervals (Patience Lake and Belle Plaine members excluding interbeds) are calculated as follows:

• Indicated Resource: 1,144.2 MMt in place sylvinite grading 29.4% KCl or 18.6% K₂O (79.1 MMt of recoverable KCl, or 49.9 MMt recoverable K₂O) and
• Inferred Resource:  868.4 MMt in place sylvinite grading 29.2% KCl or 18.5% K₂O (60.5 MMt of recoverable KCl, or 38.2 MMt of recoverable K₂O).  

Details of the solution mining scenario are presented below in Table 1:

Table 1: Solution Mining Scenario Indicated and Inferred Mineral Resource
 

*Search Radius: 2.0km (between drill holes); MMt = million tonnes; Density used 2.08; KCl = 1.58303 K₂O
**Search Radius: 2.0km inner radius and 5.0km outer radius (between drill holes); MMt = million tonnes; Density used  2.08; KCl = 1.58303 K₂O
¹ "Average K₂O Grade" and "Average KCl Grade" refer to the weighted averages.
² " In-Place Sylvinite Tonnage"   refers to Volume of Rock*Density of Sylvinite in the project area.
³ "Net K₂O Resource" and "Net KCL Resource" refer to total amount of extractable K₂O and KCl resource in the project area. (Volume of Rock*Density of Sylvinite*Grade*Deductions).  Deductions include 10% for unknown anomalies, a 35% extraction ratio, and 24% for cavern and plant losses.
⁴  Assuming 640 acres (2589988.11 m²) per section.

The resource for the potential conventional mining intervals (Patience Lake and Belle Plaine members) is calculated as follows:

• Indicated Resource:  461.5 MMt in place sylvinite grading 36.2% KCl or 22.9% K₂O (45.9 MMt in recoverable KCl, or 30.0 MMt recoverable K₂O) and
   
• Inferred Resource:  327.4 MMt in place sylvinite grading 36.4% KCl or 23.0% K₂O (32.7 MMt recoverable KCl, or 20.7 MMt recoverable K₂O).

Details of the conventional Indicated and Inferred resource are presented in Table 2 as follows:

*Search Radius: 2.0km (between drill holes); MMT = million tonnes; Density used is 2.08; KCl = 1.58303 K₂O
**Search Radius: 2.0km inner radius and 5.0km outer radius (between drill holes); MMT = million tonnes; Density used is
2.08; KCl = 1.58303 K₂O

² " In-Place Sylvinite Tonnage"   refers to Volume of Rock*Density of Sylvinite in the project area.
³ "Net K₂O Resource" and "Net KCL Resource" refer to total amount of extractable K₂O and KCl resource in the project area. (Volume of Rock*Density of Sylvinite*Grade*Deductions).  Deductions include 10% for unknown anomalies, a 35% extraction ratio, and 12% for plant losses.
⁴  Assuming 640 acres (2589988.11 m²) per section.

The resource estimate was prepared in accordance to the NI 43-101 guidelines of the Canadian securities regulators.  As required by NI 43-101, a technical report to support the resource estimate will be filed with SEDAR and be publically available within 45 days following the date of this news release.

James Walchuck, President and CEO of Encanto commented "Encanto is obviously very pleased with the resource calculations which have clearly established a substantial resource on the Muskowekwan First Nation Home Reserve.  The resource easily justifies a Preliminary Economic Assessment (PEA) which will be conducted by Wardrop, A Tetra Tech Company, ("Wardrop") A Tetra Tech engineering firm based in Saskatoon, Saskatchewan.  The PEA will apply engineering and economic principles to determine the best financially advantageous method for the future Pre-Feasibility and Feasibility studies.   Wardrop's team will carry out the PEA starting April 2011 and is expected to issue a draft report in the third quarter of this year."
