Cornish Metals Inc (AIM:CUSN, TSX-V:CUSN, OTC:SBWFF) said it has now put the first of two submersible pumps in place at the New Cooks Kitchen shaft at the South Crofty tin mine in Cornwall.
At a target depth of 360 metres below the surface, the pump, which is a key part of the mine dewatering process, required the connection and lowering of the pump on 120 three-metre-long steel pipes, which are suspended in the shaft.
In a statementm Richard Williams, Cornish Metals chief executive, said: "A big 'proper job' well done to the team at South Crofty for achieving this milestone in less time than planned.
“This pump installation is a technical exercise and the team did a fantastic job, completing the task safely with no incidents. We anticipate the second pump to be installed by the end of July."
Elsewhere, work on the Mine Water Treatment Plant continues with 95% mechanical completion, and work is now focused on the electrical and instrumentation installation.
Plant commissioning is scheduled to be completed later this summer and mine dewatering to commence immediately thereafter.
