Cornish Metals Inc (AIM:CUSN, TSX-V:CUSN, OTC:SBWFF) said it has successfully commissioned both submersible pumps recently installed in New Cook's Kitchen shaft at the South Crofty mine.in Cornwall.
The associated Variable Speed Drives have also been installed with mine water now being pumped from below the 195-fathom level to the treatment plant (MWTP).
From there, it has been diverted around the plant and returned back underground via a specially installed commissioning loop.
Once the MWTP is completed and commissioned later in the summer, the fully treated mine water will be diverted to the Red River and dewatering of the mine will commence.
Richard Williams, chief executive, said: "This is a very significant milestone for South Crofty.
"Seeing the first water being pumped out of the mine during this commissioning phase since the mine's closure 25 years ago is a truly historic moment."
