GOLD: Eastmain says higher grade a “game changer” for Eau Claire deposit

QUEBEC – Eastmain Resources of Toronto called the 51% jump in gold grades at the Eau Claire deposit a “game changer.” The deposit is part of the Clearwater project in the James Bay region.

The estimated grade of the measured and indicated portion of the underground resource is 6.2 g/t gold, an increase of 51% from two years ago. The open pit grade also rose to 5.9 g/t gold, up 46%. Recent metallurgical tests have put gold recovery at 95%.

The total resource estimate for the Eau Claire deposit is now 4.2 million measured and indicated tonnes at 6.2 g/t gold containing 826,000 oz. of gold plus 2.2 million inferred tonnes at 6.5 g/t containing 456,000 oz. of gold. Resources suitable for open pit mining are counted above 150 metres, and those for underground recovery lie between 150 and 860 metres.

Eastmain is encouraged by the new resource estimate and plans to proceed with a preliminary economic assessment at the Clearwater property. The new interpretation and estimate traced gold mineralization to a depth of 550 metres and along strike for 1,000 metres. The deposit remains open to the east.
