Imerys Talc, Rabenwald, Austria

Drilling campaign aimed to increase the LoM by adding a significant amount of ore close to the southern edge of current operation. Two (2) surface drilling rigs deployed at the southern edge of the open pit by in a regular 40x40m grid. Vertical boreholes, verified by downhole survey, provided excellent results.

Project Challenge

It has been a mildly challenging project as the mine is very well organized.

• Rig deployment in a crowded operating mine
• Water transportation and handling through sumps

• Maintain high recovery in the ore portion of the borehole
• Occasionally bad geotechnical conditions in the overburden

RESULTS

The 2020 program successfully delineated another 5 years worth of mining. The 2022 program aims to infill the previous boreholes, to increase the geological confidence in the ore estimation, and further delineate more the southern extreme of the deposit.
