350 redundancies eyed at Nifty - Aditya Birla
PERTH (miningweekly.com) – ASX-listed Aditya Birla would stand down about 350 full-time positions at its Nifty copper mine, in Western Australia, as it worked to rectify a sinkhole at the project.
The miner had previously said that it would offer voluntary redundancies at the project site, adding on Wednesday that the redundancies would remain in place until at least July 15, pending the finalisation of the investigation into the sinkhole.
The miner was currently progressing its two-phased investigation into the sinkhole, and had been granted permission by the Department of Mines and Petroleum to proceed uninterrupted with the second phase of drilling, which would involve the further probing of the aquifer, the sinkhole and the potential stope voids above the stope backs.
The objective of the phased drilling was to determine the extent of risks associated with the sinkhole to the bottom of the mine.
The results from the Phase 1 probe drilling have been analysed, and have revealed that the main aquifer in the vicinity of the underground operation remained intact, and in the same condition as in 2008, with drilling into the sinkhole confirming its location.
Aditya Birla noted that the sinkhole was filled with highly weathered and oxidised material most likely from the near-surface layer of the pit, adding that no voids, water or liquid matter were encountered in the probe holes, reducing the risk of an inrush of water or mud under the current weather conditions.
The miner added that judging by preliminary risk assessment, there was significant work required to re-establish mine infrastructure on level 12 of the Nifty operation, with the company adding that the Phase 2 drilling remained critical in completing the overall risk assessment of the mine.
The Phase 2 drilling was progressing as planned and would be completed by mid-July.
