Pitchstone Reports Uranium Results at Johnston Lake

Pitchstone Exploration Ltd. (TSX VENTURE:PXP) ("Pitchstone") announces that it
has received analytical results on all samples collected from recent drilling at
the Johnston Lake property in the eastern Athabasca Basin in Saskatchewan.
Johnston Lake is contiguous with Pitchstone's 100% owned Gumboot property.


Johnston Lake Results

As part of a larger drilling program that included the Gumboot property, three
drill holes were completed at Johnston Lake to follow up on the results of
drilling in 2010. Encouraging sandstone alteration, structure and graphitic
basement rocks were intersected in all three holes. Intervals of elevated
radioactivity in basement rocks near the sub-Athabasca unconformity were
observed in two of the holes (JL-25R & JL-27; see March 21, 2011 news release).
The analytical results confirm that the radioactivity is due to unconformity
related uranium and, with all previous drill results from both Gumboot and
Johnston Lake, are summarized in the table below.

Drill holes JL-25R and JL-27 were drilled along the east-west oriented MJ-1
conductor, and each was drilled on section with one historic hole. The MJ-1
conductor is a 3.8 kilometer segment of a 10 kilometer long conductor system at
Johnston Lake. JL-25R was drilled 40 meters south of historic hole MJ-06. A 21
meter vertical offset in the unconformity between the two holes suggests the
presence of a major fault. Unconformity uranium deposits in the Athabasca are
often associated with faults that offset the unconformity. 


Drill hole JL-27 was drilled two kilometers west of JL-25R and 30 meters north
of historic hole MJ-07. MJ-07 intersected 6.9 meters of 1.08% nickel at the
unconformity. The presence of significant uranium near the high grade base metal
mineralization suggests that there is good potential for higher grade uranium
mineralization in the area.


Initial Interest Earned

Upon completion of this drilling program, Pitchstone has surpassed the
expenditure requirements to earn an initial 49% interest in the property from
Denison Mines Corp (Denison). Notice has been given to Denison that Pitchstone
intends to proceed with the second stage earn-in which, if completed, will give
Pitchstone a 75% interest in the property. Pitchstone notes that recent results
from both Gumboot and Johnston Lake provide further evidence of widespread
unconformity related mineralization in the area. Geologically, these properties
have many of the variables associated with large, high grade unconformity
related uranium deposits.


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 mineralization.


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.
