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. He has supervised the preparation, reviewed and approved, 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 greater than 20% KCl, the combined minimum width of Sylvinite and UC Members over 4 metres-- UC Member greater than 40% Carnallite, the combined minimum width of Sylvinite and UC Members over 4 metres-- LC Member greater than 60% Carnallite+Kieserite, minimum width of 5 metres-- Kainitite Member greater than 50% Kainite, minimum width of 5 metres
The mineral 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, an 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 Technical Report prepared in accordance with NI 43-101 supporting the updated mineral resource estimates will be available under the Company's profile on SEDAR (www.sedar.com) within 45 days of this news release. The mineral resource estimates 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.
Allana continues to conduct exploration drilling on the Nova license with 17 holes completed to date and 3 holes pending. Data compilation and analysis from earlier holes are ongoing and results will be released upon completion of the entire program. Pilot solution wells continue to produce sylvinite crystal product on site which is being utilized as test material to optimize processing parameters.
