Western Potash Corp. Intersects Over Twenty Five Metres of Potash Mineralization in Fourth Well 12.5 Km South of First Mineraliz
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/23/09 -- Western Potash Corp. (the "Company") (TSX VENTURE: WPX)(FRANKFURT: AHE) is pleased to announce that the fourth well on the Milestone property has intersected strong potash mineralization over a thicker package of potash members in a combined mineralized width of over 25 meters. These results further indicate that the extent of the mineralized potash beds spans at least 12.5 km south from the first well, Milestone-001, reported previously. The Company's wholly-owned Milestone property, comprising 500 square km in area, is located approximately 30 km southeast of Regina, and is southeast of Mosaic's Belle Plaine Mine, one of the largest producing potash solution mines in the world.
Coring of the Milestone - 004 well intersected the Prairie Evaporite Formation at a vertical depth of 1,707.5 m. Visual geological evaluation of the core in conjunction with down-hole gamma ray logs indicate strong potash grades, very low carnallite content, and very promising minimum formation temperatures of 61 degrees C within the two upper members, with some carnallite present in the Esterhazy member. The magnitude of the gamma ray log from this well suggests that higher potash grades exist within the Patience Lake and Belle Plaine members as compared to previous results. The following table details the thicknesses of the potash mineralized intercepts, indicating strong potash tenor in the down-hole gamma ray logs:
Member From (m) To (m) Thickness (m)
Patience Lake 1716.6 1730.3 13.7
Belle Plaine 1732.5 1737.9 5.4
Esterhazy 1756.5 1762.5 6.0
The well presently reported is located approximately 12.5 km and 7.5 km to the southeast of wells 001 and 002 respectively, which were reported previously. All drill intercepts noted in this release are considered the true thickness of the mineralization; as the salt beds are relatively flat-lying and down-hole directional surveys indicate the hole was essentially vertical upon intersecting the salt and potash sequences.
The Company is pleased to see the presence, thicknesses and indicated grade of the potash beds in this fourth well, when considered in conjunction with the results reported for the first three wells. The Company feels that the thicknesses and grades obtained by geochemical sampling and down-hole gamma ray logging are consistent with those mined at the Belle Plaine solution mine and that it has now demonstrated regional continuity of all three potash members, spanning a strike length of over 12.5km, between the first and fourth wells.
Minimum temperature readings of 61 degrees C were recorded from this well, indicating favorable conditions for an envisioned solution mining and recovery process. These results combined with temperature readings from the previous wells, ranging between 61 degrees C to 65.5 degrees C, have confirmed the presence of the heat anomaly that attracted the Company to this project area.
The Company re-iterates that it considers formation temperature a key parameter in solution mining economics, offering advantages in solution mass-balance and savings in capital, energy and processing costs. In other words, a mine with higher temperatures will be more efficient as the solubility of potash increases with temperature such that the higher the formation temperature, the higher the yield of potassium chloride in the brine solution to be processed for potash recovery. A solution mine, accessing a higher formation temperature resource, will produce more potassium chloride in solution than an operation tapping an equivalent resource at lower formation temperatures.
The samples extracted from the three potash members will now be submitted for analysis at the SRC laboratory in Saskatoon. Results are expected to be obtained within 4 to 6 weeks.
After a review of the encouraging results from the first phase of drilling on the Milestone property, the board of Western Potash has approved an increase in the current exploration budget in order to expand the drill program and subsequently begin an initial resource calculation. The aim of the extended exploration program will be to further define the grade, and size of the potash deposit on the property. The next phase of exploration will include an additional 4 well drill program and additional 2D and 3D seismic surveys. The budget for this work is estimated at $8.5 million CAD. It is expected that the completion of this 2nd phase will allow the Company to commission an independent 43-101 resource estimate on the Milestone property. Drilling on the Milestone property will recommence as soon as all the permits are in place which is expected prior to the end of August.
