Pitchstone Receives Marble Ridge Uranium Analyses

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.

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.
