CORNISH METALS PROVIDES AN ACTIVITIES UPDATE AND 2024 OUTLOOK

 

Vancouver, January 17, 2024

Cornish Metals Inc. (AIM/TSX-V: CUSN) ("Cornish Metals" or the "Company"), a
mineral exploration and development company focused on advancing the South
Crofty tin project ("South Crofty" or the "Project") located in Cornwall,
United Kingdom, to a construction decision, is pleased to provide an update on
the progress of activities and outlook for 2024.

Highlights

 

·    Important Milestones Achieved in 2023:

o  Updated Mineral Resource Estimate ("MRE") for South Crofty Mine with a
31.6% increase to contained tin in the Indicated Mineral Resource category for
the Lower Mine;

o  Construction and commissioning of the Water Treatment Plant ("WTP");

o  Installation and commissioning of submersible pumps in New Cook's Kitchen
("NCK") shaft;

o  Commencement of dewatering of South Crofty Mine with the water level
currently down to 257 metres below the NCK shaft collar level;

o  Completion of metallurgical testwork drilling programme;

o  Better than expected results from X-Ray Transmission ("XRT") ore sorting
testwork confirming the potential to materially reduce tonnes milled, and
reduce process plant capital and operating costs;

o  Installation of two single drum winders for shaft re-access;

o  Commencement of an exploration drilling programme at the Wide Formation
target.

·    2024 Outlook:

o  Mine dewatering:

§ Dewater to 195-fathom level (~360 metres below surface) and refurbish the
pump station;

§ Progress to the second stage of dewatering of the deeper levels of the
mine;

o  Commence underground infill drilling;

o  Advance the South Crofty Feasibility Study: all study components, with the
exception of infill drilling, expected to be completed in H1 2024;

o  Preliminary Economic Assessment ("PEA") for South Crofty planned before
end of H1 2024 to provide interim guidance prior to the publication of the
Feasibility Study;

o  Complete the 14-hole / 9,000 metre Wide Formation exploration drill
programme.

 

 

Richard Williams, CEO and Director of Cornish Metals, stated: "The Cornish
Metals team worked tirelessly in 2023, achieving numerous important
milestones, while further advancing and de-risking the South Crofty project.
Chief among these are the construction of the WTP and commencement of
dewatering of the mine that continues to progress extremely well with water
levels drawing down as expected. Activity levels are expected to remain high
through 2024 with more important milestones to be met as we work to further
progress the South Crofty project towards a construction decision."

 

Mine Dewatering Progressing Well

·   Mine dewatering and water treatment to remove dissolved metals and
suspended solids prior to discharge has been underway since early November
2023 with up to 25,000m(3) per day of water being pumped and treated from
South Crofty Mine;

·     Progress is good, with the water level in the mine currently ahead
of projections despite the recent wet weather;

·     On January 17(th) the water level stood at 257 metres below the
NCK shaft collar level;

·   Water levels in historic mines adjacent to South Crofty remain
unchanged while South Crofty water levels fall, confirming that South Crofty
is not hydrologically connected to neighbouring historic mines and that the
dewatering only comprises South Crofty Mine;

·    Treated water from the WTP is being discharged into the Red River,
having a positive effect on the water quality of the river downstream of the
discharge point;

·    The treated water from South Crofty passes through a 75-kW
hydro-turbine located ahead of the discharge point that generates up to 20% of
the power consumed by the WTP. Other renewable energy opportunities are being
explored;

·    At current rates, the first stage dewatering to the 195-fathom level
(approximately 360 metres below surface) is anticipated to be completed in
early Q2-2024;

·     Refurbishment of the 195-fathom pump station and installation of
permanent pumps is planned to take place during Q2 / Q3-2024;

·    Lowering of the submersible pumps to below the 400-fathom level
(approximately 730 metres below surface) and commencement of the second stage
of dewatering is planned to commence in Q3-2024;

·   The Company maintains guidance of 18-months (from the commencement of
dewatering in November 2023) to complete dewatering of South Crofty Mine to
the 400-fathom level.

 

Feasibility Study Progress

The Company is making good progress advancing the South Crofty Feasibility
Study with a substantial amount of the study completed. All study components,
with the exception of infill drilling, are expected to be finalised in H1
2024.

The following Feasibility Study components have been completed:

·   Geotechnical testwork - televiewer investigations and geotechnical rock
testing to confirm known historical structural and rock mass property data;

·    Headframe structural modelling and refurbishment;

·    Schedule and costing for the refurbishment and recommissioning of NCK
and New Roskear shafts;

·    Numerical modelling of the proposed underground mining methods and
stope designs;

·    Phase 1 of the metallurgical testwork programme (mineralogy, physical
competency, characterisation XRT, heavy liquid separation and gravity response
testwork);

·    Concept engineering on paste backfill options and sighter testwork;

·    Ground investigations for the new mineral processing plant; and

·    Mineral processing plant design and layout, incorporating the results
of the metallurgical testwork programme and potential future throughput
expansions;

The following Feasibility Study components are underway:

·  Underground mine design and optimisation using the September 2023 South
Crofty updated Mineral Resource Estimate;

·    A mine ventilation study, underground infrastructure design and
hoisting analysis;

·    A Feasibility Study level engineering design for the paste backfill
plant;

·    Hydrogeology, environmental, social, market and closure studies; and

·    Underground drilling options review started.

Wide Formation Target Exploration Drilling

·    A 14-hole / 9,000 metre drilling programme at the Wide Formation
target in the Carn Brea South exploration area commenced in late summer 2023;

·   Drill programme to test the geometry and the continuity of tin
mineralisation within the Wide Formation target - testing an area measuring
2,500m along strike (northeast to southwest) and 500m downdip (north to
south);

·    Two drills are on-site with holes No. 7 and No. 8 currently underway;

·    Great Flat lode and Wide Formation mineralisation structures have
been intersected where expected;

·    4,700 metres drilled to date and assays will be reported when
available;

·    Drilling programme expected to be completed in summer 2024.

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 a
construction decision, as well as exploring its additional mineral rights, all
located in Cornwall, United Kingdom.

·   South Crofty is a historical, high-grade, underground tin mine that
started production in 1592 and continued operating until 1998 following over
400 years of continuous production;

·   The Project possesses Planning Permission for underground mining
(valid to 2071), to construct new processing facilities and 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 existing mine infrastructure including 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 two-thirds of the tin mined today coming from
China, Myanmar and Indonesia;

·    There is no primary tin production in Europe or North America;

·    Tin connects almost all electronic and electrical infrastructure,
making it critical to the energy transition - 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.

·    Cornish Metals has a growing team of skilled people, local to
Cornwall, and the Project could generate 250 - 300 direct jobs.

An updated Mineral Resource was completed in September 2023 with a 39%
increase in tonnes and 32% increase in contained tin in the Indicated category
for the Lower Mine (see news release dated September 13, 2023
