Pitchstone Reports Athabasca Drilling Results

Pitchstone Exploration Ltd. (TSX VENTURE:PXP) ("Pitchstone") announces that its
summer exploration program of core drilling on two eastern Athabasca Basin
properties has been completed as planned. Drilling was completed on Pitchstone's
100% owned Gumboot property, and on the Wolverine property that was optioned in
early 2009 to the Japan Oil, Gas and Metals National Corporation ("JOGMEC").


Gumboot

Drilling at Gumboot consisted of three holes (GB-28, 29 and 30) totalling 2,359
meters that tested strike extensions to the north and south of known
mineralization. Significant alteration and/or mineralization were observed near
the unconformity in all three holes.


The first hole, GB-28, was drilled as a 100 meter step-out along strike to the
north of GB-23 (0.3 meters of 0.53% U3O8, 1.92% Ni - see March 21, 2011 news
release). It intersected a wide interval of low grade base metal mineralization
and anomalous uranium, beginning six meters beneath the sub-Athabasca
unconformity, averaging 0.18% Ni and 0.01% U3O8 over 7.9 meters. Individual
samples within the interval contain up to 2.3% Ni and 0.03% U3O8.


GB-29 was drilled 600 meters south of GB-28 as a 100 meter step-out along strike
to the south of GB-14 (0.4 meters of 3.32% Ni and 0.01% U3O8). While no
mineralization was intersected, both the basement and sandstone near the
unconformity are strongly altered. Based on rock types encountered, it is likely
that the drill hole overshot the target zone and entered the basement in
gneisses that are in the footwall (west) of the mineralized zone.


GB-30 encountered the strongest uranium mineralization of the program, and was a
500 meter step out along strike to the north of GB-28. The Gumboot mineralized
zone was intersected along with strong alteration and anomalous metal
concentrations in both the sandstone and basement. Mineralization includes 0.2
meters averaging 0.22% U3O8, 0.15% Ni and 0.20% Co within a 1.7 meter basement
interval that averages 0.03% U3O8, 0.07% Ni and 0.11% Co.


The five kilometer long Gumboot conductive zone is located 650 meters below
surface and has been tested over a strike length of 1,200 meters. The entire
1,200 meter portion that has been drilled is strongly altered, sporadically
mineralized, and open along strike in both directions (see maps at
www.pitchstone.net). Additional drilling of this highly anomalous target is
planned.


Wolverine

Five drill holes were also completed on the Wolverine property to follow up on
the results of drilling in 2010, which intersected a narrow interval of low
grade uranium associated with a much wider zone of hematite breccia within
basement rocks about 200 meters below surface. While hematite breccia was
intersected in all five of the Wolverine drill holes, no significantly elevated
radioactivity was observed. Geochemical analyses are pending and decisions on
further exploration at Wolverine will be made when those are received.


Black Bear

Pitchstone continues to aggressively seek new uranium opportunities and has
recently staked a 2,000 hectare property in the eastern Athabasca Basin called
Black Bear. Located 18 kilometers south of the Cigar Lake uranium mine and 33
kilometers northeast of the Macarthur River uranium mine, the property has
several important attributes, including:




--  Its location in the eastern Athabasca Basin near producing uranium
    mines,
--  Relatively thin (200-350 meters) sandstone cover,
--  The presence of a large magnetic low zone that indicates the presence of
    Wollaston Group metasediments. This low extends westward to the
    Macarthur River uranium mine and the Yalowega Lake and Dolmen Lake
    uranium deposits,
--  An east-west linear magnetic feature that suggests the presence of a
    fault zone,
--  A lack of previous drilling (only one historic drill hole on the
    property).



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 done by SRC Geoanalytical
Laboratories, Saskatoon. A partial digestion with fluorimetric analysis was used
for initial uranium determinations, and then all samples containing greater than
100 ppm uranium were re-analyzed with ICP. Pitchstone utilizes internally and
externally submitted standard reference materials for quality assurance and
quality control of the sample preparation and analyses. There is insufficient
information to estimate the true thickness of the intersections.


About Pitchstone

Pitchstone is exploring for uranium in three proven districts in Canada and
Namibia. The property portfolio features 13 projects in the eastern Athabasca
Basin, Saskatchewan, five 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.
