CORNISH METALS SUCCESSFULLY COMMISSIONS SUBMERSIBLE PUMPS AND VARIABLE SPEED
DRIVES

 

Vancouver, July 26, 2023

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
(https://cornishmetals.com/projects/uk/south-crofty-project-update-photos/) .

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
(https://cornishmetals.com/news/2023/cornish-metals-reports-that-first-submersible-pump-fully-installed-to-360m-depth/)
and July 18, 2023
(https://cornishmetals.com/news/2023/cornish-metals-installs-second-submersible-pump-commences-commissioning-of-variable-speed-drives-for-the-pumps-and-signs-100/)
). 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 (m(3)) 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 4(th) 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:
