VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/30/11 -- Pitchstone Exploration Ltd. (TSX VENTURE: PXP) ('Pitchstone') announces that analytical results have been received from a recently completed reverse circulation drilling program at the Marble Ridge zone. Marble Ridge is a 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).
Twenty eight drill holes were completed in the February 2011 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 February 28, 2011 news release).
Twelve of the recently completed drill holes were mineralized, bringing the total number of mineralized intersections to date at Marble Ridge to 20. The table below lists all of the mineralized intervals, including those drilled prior to February, 2011.

(i) Drilled Prior to the February 2011 Drilling Program and Reported
Previously
These results confirm that uranium and vanadium mineralization at Marble Ridge occurs within a calcrete paleochannel that is now estimated to be at least 1,900 meters long and 200 meters wide. The mineralization is open along strike. Pitchstone is also encouraged by the potential to find additional mineralized paleochannels within the 500 square kilometer Dome North area. More drilling at Marble Ridge and at other uranium targets at Dome North is planned.
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 Pitchstone
Pitchstone 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.
