Cornish Metals Successfully Commissions Submersible Pumps and Variable Speed Drives
27 7월 2023 - 3:00PM
Cornish Metals Inc. (
TSX-V/AIM:
CUSN) (“Cornish Metals” or the “Company”), a mineral
exploration and development company focused on its South Crofty tin
project in Cornwall, United Kingdom, is pleased to announce that it
has successfully commissioned both submersible pumps that were
recently installed in New Cook’s Kitchen (“NCK”) shaft and their
associated Variable Speed Drives (“VSDs”) – see photos here.
Richard Williams, CEO and Director,
stated “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. Our project team has worked extremely hard
to install and commission the pumps and drives safely and
efficiently. We have also been supported by a small army of
dedicated local contractors along with equipment manufacturers and
suppliers, so a big thank you to everyone involved in the project
to date.”
Submersible Pump and VSD
Commissioning
Two KSB BSX 463/5 specialist high-head 950
kilowatt (“kW”) vertical submersible pumps manufactured and
supplied by KSB Ltd have been installed in the NCK shaft, both at a
depth of approximately 360m below surface (see news releases dated
June 26, 2023 and July 18, 2023). The pumps are controlled by two
Schneider Electric Altivar ATV 1200 variable speed drives supplied
through Siemag Tecberg UK. The VSDs enable the permitted 25,000
cubic metres (m3) per day pumping rate to the Mine Water Treatment
Plant (“MWTP”) to be maintained as the water level in the shaft
drops and the pumping head increases.
Teams from Cornish Metals, Siemag Tecberg and
Schneider Electric have been on-site for the last two weeks testing
the pumps and VSDs. The two pumps and both VSDs have now been
successfully commissioned and run through a series of performance
tests to demonstrate their ability to meet the target flow rate to
the MWTP.
The pumps have been pumping mine water from
below the 195 fathom level to the MWTP where 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.
Background
- South Crofty is a historic, high-grade, underground tin mine
that started production in the sixteenth century, and continued
operating until its closure in 1998;
- The Project possesses Planning Permission for underground
mining, valid to 2071, Planning Permission to construct a mine
water treatment plant, new processing facilities, all necessary
site infrastructure, and an Environmental Permit to dewater the
mine;
- South Crofty has the 4th highest grade tin Mineral Resource
globally and benefits from the presence of multiple shafts that can
be used for future operations;
- Tin is a Critical Mineral as defined by the UK, USA, and
Canadian governments, with approximately 75% of the tin mined today
coming from China, Myanmar and Indonesia;
- There is no primary tin production in Europe or North
America;
- Responsible sourcing of critical minerals and security of
supply are key factors in the energy transition and technology
growth;
- South Crofty benefits from strong local community and regional
and national government support. The Project could generate 250 –
300 direct jobs.
ABOUT CORNISH METALS
Cornish Metals is a dual-listed company (AIM and
TSX-V: CUSN) focused on advancing the South Crofty high-grade,
underground tin project through to delivery of a Feasibility Study,
as well as exploring its additional mineral rights, all located in
Cornwall, South West England. The former producing South Crofty tin
mine is located beneath the towns of Pool and Camborne, and closed
in 1998 following over 400 years of continuous production. Since
acquiring the project in 2016, Cornish Metals has completed and
published maiden NI 43-101 Mineral Resources for South Crofty using
the vast archive of historical production data and more recent
drilling completed between 2007 and 2013. Additionally, Cornish
Metals has undertaken extensive pilot-scale water treatment trials
and successfully applied for and received the necessary
environmental permits to abstract, treat and discharge mine water
in order to dewater the mine. Planning permissions for the
operation of the mine and re-development of the surface facilities
have been secured and construction of the water treatment plant is
currently well underway.
An updated Mineral Resource was completed in
June 2021 as summarised below:
