COPPER-GOLD EXPLORATION: High grades from potential underground Minto mine

YUKON - Capstone Mining of Vancouver has intersected grades as high as 5.1% Cu from area 2/118 extensions as it tests the potential for developing an underground operation at its Minto copper-gold mine 240 km north of Whitehorse. Results from area 2/118 included 5.1% Cu and 1.7 g/t Au over 4.0 metres and 2.3% Cu and 1.0 g/t Au over 14.0 metres. From the Copper Keel prospect, the best assay was3.3% Cu and 2.17 g/t Au over 4.1 metres.

Drilling is suspended for the spring thaw and to allow time to complete a deep-imaging IP survey. Drilling is to resume in June with two rigs.

The Minto open pit and concentrator reached commercial production on Oct 1, 2007. Target production in 2010 is 50 million to 55 million lb of copper contained in concentrates.
