Toronto-based Allana Potash Corp. (TSE:AAA)(OTCQX:ALLRF) announced Tuesday that it has intersected three zones of strong potash mineralization in hole DK-11-28, located in the northwestern portion of its 154,000-hectare potash concession block in Ethiopia.
The hole, which was targeted to test potash mineralization west of hole 15, returned a strong Sylvinite Zone at a depth of 198.8 metres, which yielded 40.27% KCI (the composite grade of all four potash-bearing beds including sylvinite, upper and lower carnallite and kainitite) over 2.56 metres.
The Kainitite Zone was also intersected deeper in the hole at a depth of 266.43 metres, and returned 21.98% KCI over 8.39 metres.
President and CEO, Farhad Abasov, said: "Allana continues to be encouraged by the continuity and strength of potash mineralization in the northwestern portion of the property as exhibited by the results of Hole 28.
"This area continues to yield high grade potash in the Sylvinite and Kainitite zones which management believes will allow Allana to upgrade mineral resources from Inferred to Measured and Indicated categories as well as add to the Inferred category."
The potash zones remain open to the north and northeast of hole 28, the company said, which bodes well for expansion of the resource.
Abasov continued: "The relatively shallow and high grade nature of the Sylvinite Zone make this area ideal for solution mining with recovery through solar evaporation."
Hole 28 is located in the northwestern part of the concession block west of Hole 15 and east of the historic Musley Deposit, suggesting that potash mineralization at Musley continues.
Exploration drilling is continuing in the western part of the property as part of the infill drilling program designed to add resources and boast confidence by reducing the spacing between holes, allowing more material to qualify for measured and indicated mineral resource categories.
An updated NI 43-101 compliant resource report in late June estimated total measured and indicated resources of 673 million tonnes, with an average grade of 18.65% potash, or KCI, Inferred mineral resources stand at 596 million tonnes with an average grade of 19.96% KCI. A new estimate is expected by year-end.
