Pitchstone Completes Namibia Uranium Drilling Program

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 28, 2011) - Pitchstone Exploration Ltd. (TSX VENTURE:PXP - News; "Pitchstone") announces that a program of reverse circulation drilling has been completed at the Marble Ridge zone of calcrete-hosted uranium mineralization on the Dome property in Namibia. The property location relative to the nearby Rossing and Langer Heinrich uranium mines, and other uranium occurrences in the Erongo region, is illustrated on Pitchstone's website (www.pitchstone.net).A total of 28 drill holes have been completed in the current program to follow up on results from drilling in 2010 that intersected a horizontal, near surface layer of uranium and vanadium mineralization in calcrete (see October 13, 2010 news release). The layer is generally 1 to 2 meters thick and was defined over an area measuring approximately 400 x 200 meters by the 2010 drilling.Down hole total gamma probe results indicate that 11 of the 28 recently completed drill holes have intersected elevated radioactivity within calcrete at depths between 4 and 15 meters below surface. The radioactive calcrete is within an interpreted paleo-channel that is currently indicated to be 1,900 meters long and 200 meters wide. All drill holes completed to date within the paleo-channel exhibit elevated radioactivity and the feature is still open in several directions. The probe results suggest that the thickness and grade of the radioactive intervals are similar to those reported from previous campaigns. Samples of all intervals of elevated radioactivity have been collected and submitted to a laboratory for geochemical analysis and results are pending.Steve Blower, P.Geo., President and CEO of Pitchstone, is the Qualified Person for the purposes of NI 43-101 with respect to the technical information in this news release. Sample preparation and analyses were completed by Bureau Veritas in Swakopmund, Namibia. A multi-element ICP-MS/AES analysis was completed on the samples after a mixed acid, near-total digestion. Pitchstone utilizes internally and externally submitted standard reference materials for quality assurance and quality control of the sample preparation and analyses. Dome is part of a uranium exploration joint venture between Pitchstone (69%) and private company Manica Minerals Ltd. (31%) through Manica's wholly-owned subsidiary Cheetah Minerals Exploration Ltd. Pitchstone's exploration programs in Namibia are carried out by Cape Town based Remote Exploration Services on behalf of the joint venture.About PitchstonePitchstone is exploring for uranium in three proven districts in Canada and Namibia. The property portfolio features 11 projects in the eastern Athabasca Basin, Saskatchewan, three of which are 100% owned. In addition, there is a joint venture on two projects in Namibia and several joint venture projects in the Hornby Bay Basin, Nunavut. Pitchstone benefits from the collaboration of a unique group of geologists with extensive uranium exploration and production experience.On behalf of the Board,Steven J.
