Pitchstone Exploration Ltd. ('Pitchstone') is pleased to report that summer exploration activities have begun in the Athabasca Basin, Saskatchewan, with drilling having commenced on the Wolverine property. Wolverine was optioned to Japan Oil, Gas and Metals National Corporation ('JOGMEC') in 2009. Also, airborne geophysical surveying is expected to begin within the next two weeks on the Dome property in Namibia. Dome is part of a uranium exploration joint venture between Pitchstone (64%) and private company Manica Minerals Ltd. (36%) through Manica's wholly-owned subsidiary Cheetah Minerals Exploration Ltd.

Athabasca

Geophysical surveying consisting of ground gravity and DC-resistivity surveys was completed at Wolverine during January to April, 2010 in preparation for a diamond drilling program that has now commenced. This first phase of drilling consists of four drill holes totaling 1,280 meters that tests two target areas. All exploration on the Wolverine property is being funded by JOGMEC. Other work planned for the summer in the Athabasca basin includes drilling at three other properties: Gumboot, Johnston Lake and Candle.

Namibia

High definition helicopter-borne magnetic and radiometric surveying is expected to commence within the next two weeks on the Dome property in Namibia. The 1,880 line kilometer survey is designed to aid in the mapping of Damaran stratigraphy and leucogranite (commonly referred to as Alaskite) at Dome North. A program of geological mapping and sampling at Dome North completed in March, 2010 returned uranium values up to 0.61% U3O8 from a grab sample of leucogranite containing visible yellow uranium oxide mineralization (see May 25, 2010 news release).
