GOLD-SILVER: Klaza inferred resource grows to 1.4M oz Au

YUKON – Rockhaven Resources of Vancouver has increased the gold and silver content of its Klaza property in the Dawson Range gold belt in the southern part of the territory. The new number includes 2015 drilling from both the Klaza and BRX zones.

The inferred resource now totals 2.4 million pit constrained tonnes grading 5.12 g/t Au and 94.51 g/t Ag, plus lead and zinc vales. The underground inferred resource is 7.0 million tonnes grading 4.27 g/t Au and 87.18 g/t Au (plus lead and zinc). Together the resource is 9.4 million inferred tonnes containing 1.4 million oz of gold and 27.0 million oz of silver.

Rockhaven said there is a 53% increase in the amount of contained gold at the property because the resource model was reinterpreted following the 2015 drill program.

A process flowsheet has also been designed for the Klaza mineralization. It includes sequential flotation of lead, zinc and an arsenopyrite-enriched concentrate that will be treated by pressure oxidation and leaching. Precious metals will also be leached from flotation tails. Final products will be gold doré and precious metals-rich concentrates of lead and zinc.
