CORNISH METALS COMMENCES WET COMMISSIONING OF SOUTH CROFTY MINE
WATER TREATMENT PLANT
Vancouver, September 27, 2023
Cornish Metals Inc. (AIM/TSX-V: CUSN) ("Cornish Metals" or the
"Company"), a mineral exploration and development company focused
on its South Crofty Tin Project ("South Crofty" or the "Project")
in Cornwall, United Kingdom, is pleased to report that it has
commenced wet commissioning of its newly constructed Mine Water
Treatment Plant ("MWTP") at South Crofty.
Key Points
-- The MWTP is designed to treat 25,000m(3) /day of water pumped
directly from South Crofty Mine;
-- The plant uses the proven High Density Sludge ("HDS") process
technology to treat raw mine water and meet the Company's permitted
standards for discharge into the nearby Red River;
-- Cornish Metals' project delivery team is being supported by
the plant designer, equipment suppliers and contractors to fully
test and commission every aspect of the process before commencing
discharge to the Red River; and
-- Commissioning and building of the high density sludge bed is
expected to take up to three weeks, with full dewatering of the
mine anticipated to commence in October.
Richard Williams, CEO and Director of Cornish Metals, stated;
"The commencement of wet commissioning at the South Crofty MWTP is
another exciting step towards the dewatering of South Crofty Mine.
Our project team, supported by a small army of dedicated local
contractors, has worked extremely hard over the last 12 months to
take the MWTP from a conceptual flowsheet design through to a fully
constructed plant."
MWTP Commissioning
The MWTP uses the proven HDS water treatment technology to
remove metals and other contaminants from the mine water. The plant
commissioning process takes place in several stages:
1. Fill all the reaction tanks with water and check for leaks;
2. Electrically test each of the motor and control circuits,
commission the reagent addition modules, supplied as package plants
from third party suppliers, and receive first fills of all
reagents; and
3. Start running the plant and treating the water to allow a bed
of thickened (high density) sludge to build up within the plant.
This sludge building step is an essential part of the HDS process
and is required to achieve the permitted water quality standards
for discharge. During the sludge building process, the raw water
from the mine is treated through the plant and then re-circulated
back into the mine. Not until the plant is fully operational and
performing to the required standards will any treated water be
discharged to the Red River.
Background
-- South Crofty is a historical, high-grade, underground tin
mine that started production in the sixteenth century, and
continued operating until 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.
