Cornish Metals has said activities "continue at a good pace" for the South Crofty Tin Project.
The Canadian-headquartered mining company has updated inventors to say it has made “good progress”, as it targets production in 2026 at the historic mine, near Redruth in Cornwall, which closed in 1998.
The AIM-listed firm confirmed that the commencement of dewatering is on track for later this summer. The company provided details on the first submersible pump, which has been suspended in the New Cooks Kitchen shaft.
This is the first of two to be installed in the shaft for stage one of the two-stage mine dewatering programme. Installation of the second pump is expected to commence before the end of June.

Richard Williams, chief executive and director, of Cornish Metals commented: "Activities at South Crofty continue at a good pace with the commencement of dewatering on-track for later this summer. Good progress is also being made with many aspects of the Feasibility Study to examining the re-opening of South Crofty. Initial results are very encouraging. The mine site team have also reached another important milestone with the installation of the first submersible pump into NCK shaft now underway."
Last year the company raised £40.5m in funding which it will use to construct a mine water treatment plant, as well as dewater the mine, and complete a feasibility study.
In the update the company summarised the continued work on its feasibility study. Noting so far early gravity response results have been "very good and are in line with previous operational results".
Numerical modelling of the proposed underground mining methods and stope designs has been completed by MiningOne. Results confirm the historical operating data and that the ground conditions and excavation stability are expected to be very good.
In addition, the mine geological team continue to digitise and incorporate historic assay data into the South Crofty Mineral Resource model.
