McEwen Mining is reporting an increase in the indicated and inferred resources at its Grey Fox property near Timmins.

In a July 25 news release, the company said the indicated resource estimate has increased by 102,000 ounces of gold (22 per cent), while the inferred resource estimate has increased by 567,000 (35 per cent). The new numbers were based on a grade of 7.10 grams per tonne of gold.

“The Grey Fox deposit resource estimate is now 567,000 gold ounces at a grade of 7.10 grams per tonne in the indicated category, with an additional 135,000 gold ounces at a grade of 6.19 grams per tonne in the inferred category,” the company reported.

The changes came following a new geological and structural interpretation of two zones: 147 and 147NE.

“The highest grades and best widths of mineralization at Grey Fox are concentrated at the intersections of NE-SW trending structure and favourable iron rich host rocks,” said Sylvain Guerard, McEwen’s senior vice-president of exploration, in a news release.

“This has been an important geological observation because we believe there are numerous other similar targets on our property that will be tested this year.”

McEwen said it was continuing with its exploration program and would provide updates through the year.

Additionally, the company said a study was underway to determine the economic feasibility of mining the Grey Fox deposit using a central underground ramp system.
