Hathor Upgrades Mineral Resource Estimate for Roughrider Uranium Deposit

Hathor Exploration Limited (TSXV:HAT) reports the updated and upgraded mineral resource estimate for the Roughrider uranium deposit, Athabasca Basin, Saskatchewan. 

The press release is quoted as saying:

The estimation strategy for the Roughrider deposit consists of estimating U₃O₈ and other elements, and specific gravity into a block model informed from composited data and constrained by fifteen resource domains. Uranium oxide (U₃O₈) grades were estimated using three estimation runs. The first estimation run is based on a search ellipse with ranges equal to the largest variogram model structure the second run consists of a search ellipse range equal to twice the variogram range. The third estimation ellipse consist of a search ellipse generally three times the search ellipse range. The bulk of blocks are estimated in the first run. Second and third estimation runs adds only about 18 and 9% more material, respectively.
