May 11, 2011 – Purepoint Uranium Group Inc. (TSX:PTU.V) has commenced building a series of three dimensional numerical earth models of the Turnor Lake region in Canada’s Athabasca Basin to further identify and prioritize drill hole targets for the company’s next drill program on this property. The work is being undertaken by Mira Geoscience of Westmount Quebec. With offices both in Canada and Australia, Mira specializes in multi-disciplinary quantitative data integration utilizing state-of-the-art technology such as GOCAD and 3D geophysical inversion software developed by the University of British Columbia and Fullagar Geophysics. Mira has substantial experience in the Athabasca Basin, having worked with clients such as Cameco and Areva.
“Our drill results at Turnor Lake have consistently demonstrated that a widespread uranium mineralizing event occurred on the property” said Scott Frostad, Vice President Exploration, Purepoint. “By re-analyzing those geochemical and geological results against our extensive geophysical data within a 3D model, we will ensure our next drill program is targeting the areas with the best potential for high grade uranium mineralization”.
Highlights of the Mira Targeting Workflow Process
- 3D data compilation in GOCAD;
- Re-examination of each dataset and cross-correlating interpretations to develop and support spatial and quantitative relationships;
- Creation of a 3D lithological model from interpreted cross-sections, drill hole information and surface/bedrock geology;
- Interpretation of geophysical data in tight integration with the geological model with newly created geophysical inversions, allowing the geophysical data to be represented by a 3D distribution of physical rock properties (e.g. density, susceptibility, resistivity models);
- Computation of geochemistry models using a 3D geostatistical estimation process similar to grade modeling;
- Performing mineral potential modelling using the GOCAD Mining Suite Targeting Workflow to extract the best exploration targets.
Turnor Lake
The Turnor Lake Project is 100% owned by Purepoint. This 9,705 hectare property covers graphitic electromagnetic (EM) conductors that are directly associated with high grade uranium showings on adjoining properties, namely Cameco’s La Rocque occurrence (up to 33.9% U3O8 over 5.5 m) to the west and Areva’s HLH-50 intercept (5.2% U3O8 over 0.38 m) located to the south. The project lies in close proximity to several uranium deposits, including Midwest Lake, McClean Lake and Eagle Point, and has a shallow depth to the unconformity of less than 200 metres in most areas.
A series of detailed geophysical surveys have been conducted on the property since November 2006 and numerous drill targets, including EM conductors and structurally complex areas having evidence of intersecting structures, remain untested.
About Purepoint
Purepoint Uranium Group Inc. is focused on the precision exploration of its thirteen projects in the Canadian Athabasca Basin. Purepoint proudly maintains project ventures in the Basin with the three largest uranium producers in the world, Cameco Corporation, AREVA and Rio Tinto. Established in the Athabasca Basin well before the initial resurgence in uranium earlier last decade, Purepoint is actively advancing a large portfolio of multiple drill targets in the world’s richest uranium region.
