Canadian mineral exploration company Ashburton Ventures has commenced exploration on its Sienna West uranium claims under the Sienna Uranium Project in northern Saskatchewan, Canada.

A recent exploration on the Sienna claims in the Athabasca Basin observed several boulders with radioactivity measuring more than 200 counts per second on a hand-held radiation detector.

The Sienna West uranium claims are situated 40km southwest of the Sienna claims and have Geological Survey of Canada lake sediment samples with as high as 3.9-7.7 ppm uranium.

Ashburton Ventures is a junior exploration company with active uranium and gold exploration projects in Nevada and Saskatchewan.
