Cornish Metals has installed the first of two submersible pumps at the South Crofty tin mine in Cornwall.
The Canadian-headquartered mining company has updated investors to say the pump has been installed to the target depth of 360m below surface in New Cooks Kitchen shaft at the mine near Redruth, which closed in 1998.
The pump is "an important milestone" in the AIM-listed firm's plans for dewatering South Crofty mine later this summer.
