Darby-Candle Drilling

Pitchstone Exploration Ltd. ("Pitchstone") reports that diamond drilling is underway on the Darby-Candle project in the eastern Athabasca Basin, Saskatchewan. The winter road from the Cigar Lake mine to the project was opened in January. A camp has been established, crew and equipment mobilized and drilling has commenced. This exploration is funded by sxr Uranium One Inc. (TSX: SXR), which is earning a 50% interest in five of Pitchstone's Athabasca Basin projects.

A total of 55 km of conductive zones have been outlined on the Darby-Candle project. The primary objective of the current drill program is to provide an initial test of some of the conductors that have not previously been drilled. A total of 5,900 m of drilling has been budgeted for this phase of work and the intention is to drill throughout the season as long as winter road access is available. The Darby-Candle claims adjoin the Cigar Lake property to the west and are 20 km northeast of the McArthur River mine; these are the two highest grade, large uranium deposits ever discovered in the world.

 

Fireweed & Gumboot Exploration

A total of 178 km of grid lines have been cut on Pitchstone's 100% owned Fireweed and Gumboot projects to facilitate moving loop electromagnetic surveying (MLEM). Quantec Geoscience is doing the MLEM surveys and to date the work is 75% complete. MLEM was selected as the most accurate method of locating basement conductive zones with which the high grade Athabasca deposits are typically associated.

Pitchstone is a uranium exploration company with eight exploration projects in the eastern Athabasca Basin and three in the Hornby Bay Basin, Nunavut and NWT. These projects include a 50% interest in an inferred uranium resource in the Mountain Lake deposit, Nunavut (NI 43-101 compliant estimate; News Release 05.01, Oct. 14, 2005).
