FROG’S LEG MEASURED AND INDICATED RESOURCE HAS
SURPASSED THE ONE MILLION OUNCES MILESTONE HIGHLIGHTS:
• Dioro confirms another increase in the measured and indicated resource at the Frog’s Leg mine.
• The increase of 60,000 ounces to 1,001,000 ounces at an average grade of 7.0g/t.
• Majority of increase was in the highest quality category, Measured Resource which increased by 23%.
• Reserve update to be completed in July 2009.
Dioro Exploration NL (“Dioro” or the “Company”) is pleased to announce a further update to the resource at the 49% Dioro-owned Frog’s Leg mine. The Measured and Indicated (“M&I”) resource now contains 1.001 million ounces of gold (490,500 attributable to Dioro) when allowing for depletion due to mine production. Further growth can be expected with an additional 192,000 ounces currently contained in the inferred category (94,000 ounces attributable to Dioro). The deposit still remains open at depth.
The resources at the Frog’s Leg deposit have grown in every one of the last three years with a 95% increase in 2007, 37% increase in 2008 and 6% so far in 2009. In addition there has been an increase in grade of both the measured and indicated categories lifting the average grade of total measured and indicated resources to 7.0g/t.
An Ore Reserve update is scheduled to be completed in July 2009.
At the time of the last publication of Ore Reserves at the Frog’s Leg Mine (in December 2007) there was an 86% conversion from Measured and Indicated Resource to Ore
Reserve. It is expected that the July 2009 update will show a similar level of conversion of resource to reserve. This will result in a significantly enhanced mine life and aggregate life-of-mine cash flows for the Frog’s Leg mine.
