Woulfe Mining has received permit approval for the production adit at its Sangdong tungsten / molybdenum mine in South Korea.
The production adit, which will be located near to the crusher site, will access the mineralisation inside the decline, and use modern bulk mining equipment.
The mine contains indicated resource of 5.9Mt at 0.42% tungsten oxide, and inferred resource of 18.5 nukkuib tons at 0.45% tungsten oxide.
Woulfe Mining will start the development work on completion of final design portal.
Woulfe Mining CEO and president Brian Wesson said that the development will also provide access to mine bulk samples for metallurgical pilot plant test work to optimise recovery and production of ammonia paratungstate.
