YUKON – Preliminary results from metallurgical tests of material from the Revenue zone at the Freegold Mountain copper-gold project show high recovery rates for all metals, says Northern Freegold Resources of Vancouver. The Freegold Mountain property is approximately 70 km from Carmacks.

The weighted average recovery of copper from the sample was 92%; gold was 74%, molybdenum was 81%, and silver was 59%. The tests were conducted by SGS Minerals.

Northern Freegold says the tests were done on the assumption of a conventional mill flowsheet. Grinding would be followed by gravity separation of the precious metals. The flotation circuits would produce separate copper and moly concentrates. Lastly, cyanidation would recovery gold and silver from the cleaner scavenger tails.

The Revenue zone is one of two deposits at Freegold Mountain. The inferred resource is 101 million tonnes grading 0.38 g/t Au, 2.49 g/t Ag, 0.11% Cu, and 0.04$ Mo using a cut-off of 0.5 g/t AuEq. Total contained metal is estimated to be the equivalent of 3.66 million oz of gold.
