The new exposure of a deposit is connected to high investment costs.
Particularly the conception of a suitable and, at the same time, economically working ore processing must be handled with the greatest attention.
An exploration drilling has to be done in order to design a statistically meaningful dressing cycle.
The exploration drilling – a shaft with an inside diameter of 3.0 m and a depth of 175 m – was integrated into the orientation concept for the deposit. Later, this shaft will serve as a ventilation shaft and second escape route.
The exploration drilling is about 600 m in the north-east of the premises (F).
AIM OF THE EXPLORATION MINING
- Extraction of approx. 3,000 tons of tungsten from deposit 4.
- Construction of a pilot dressing plant.
- Simulation of the future dressing process.
- Foundation for the development of a big dressing plant in view to a regular operation of the mine.
- Basis of the bankable feasibility study.
