GOLD-TUNGSTEN: Process developed for Mega’s Monument Bay ore

MANITOBA – Mega Precious Metals of Thunder Bay has been seeking a metallurgical process that will recover gold and by-product tungsten from the ore of the Twin Lakes deposit at its Monument Bay property between Thompson and Winnipeg. Just such a process has been developed by Thibault & Associates using drill core samples from the deposit.

The bench scale tests (using both metallurgical and hydrometallurgical processing methods) were based on samples of drill core containing 2.27 g/t Au and 0.0021% WO₃ from the Gold zone and 1.32 g/t Au with 0.42% WO₃ from the Gold-Tungsten zone.

Gold recovery from the Gold zone sample totaled 91.4%.

Tungsten recovery of 84.9% was achieved using bulk sulphide flotation followed by tungsten rougher flotation on material from the Gold-Tungsten zone. The recovery of gold and a tungsten by-product from this zone has the potential to boost the economics of the project.
