Pitchstone Exploration Ltd.: Athabasca Exploration Results & Financial Update

- Darby-Candle drilling results - EM survey completed at Lynx Lake - Financial update & AGM date

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 19, 2007) - Pitchstone Exploration Ltd. (TSX VENTURE:PXP) ("Pitchstone") is pleased to provide an update on exploration in the Athabasca Basin, Saskatchewan and key points from its fiscal 2006 audited financial statements.

Darby-Candle Drilling

Drill hole CD-08R, completed on the Candle property during March, intersected a zone of clay-altered, friable sandstone above the unconformity from 610-614 m. The unconformity between the Athabasca Group sandstone and older basement rocks was intersected at 617.25 m. Weak radioactivity was encountered over 0.1 m intervals at the unconformity and at a fault zone at 627.2 m. Samples have been submitted for geochemical analysis and results are pending. There was also a zone of weak radioactivity detected with a drill hole probe within the zone of clay-altered sandstone above the unconformity, however, much of this strongly altered interval was not recovered in drill core.

Drill hole CD-08R intersected the unconformity 70 m east of drill hole CD-02, which was completed in 2006. As previously reported (see May 1, 2006 news release) CD-02 returned the highest uranium geochemistry results on the property to date, including 0.5 m from 599.6 to 600.1 m immediately above the unconformity that contained 422 ppm uranium (0.05% U3O8).

As a result of this drilling, Pitchstone and sxr Uranium One Inc ("Uranium One") have now jointly earned a 75% interest in the Candle property. The remaining 25% interest is held by JCU (Canada) Exploration Company, Limited, and the parties will be proceeding on a 75:25 joint venture basis for all future exploration on Candle. The Darby-Candle, Waterfound, Lynx Lake and Moon Lake properties are joint ventured 50:50 with Uranium One. Drilling on joint ventured properties, including Darby-Candle, and on other 100% Pitchstone owned properties in the eastern Athabasca Basin, is planned to resume in May after spring break-up.

Athabasca Basin EM Surveys

A 25 line km fixed-loop electromagnetic (EM) survey has been completed on the Lynx Lake property. Preliminary results indicate that weak conductive responses were recorded at Lynx Lake and also during a recently completed EM survey at Darby (see March 28, 2007 news release).
