Redmoor Update

Deep Digital Cornwall Datasets General Release

Soil samples indicate significant Tin-Tungsten mineralisation trends near
surface

Strategic Minerals plc (AIM: SML; USOTC: SMCDY), a profitable producing
mineral company, is pleased to announce that its wholly owned subsidiary
Cornwall Resources Limited ("CRL") has today released the first data from the
'Deep Digital Cornwall' project ("DDC"). DDC is led by the University of
Exeter's Camborne School of Mines ("CSM"), in which CRL and Cornish Lithium
Ltd are delivery partners. DDC is funded by the European Regional Development
Fund ("ERDF"), through HM Department for Levelling Up, Housing and Communities
("DLUHC").

Highlights:

·    New areas of mineral prospectivity for Tin and Tungsten, within the
Company's license area to the west of Redmoor, identified in DDC soil sampling
results being released to the public.

·    Tin, including 1% Sn (10,000ppm), or 1.06% Sn(Eq) in soil sample
DDC001275, found in mineralised trend A and includes potentially significant
results for further follow-up.

·  Likely presence of two subsurface granite upwellings identified in Reid
Geophysics' 3D model interpretation of the granite body and accompanying
reports.

·    DDC project entering the second, and final phase.

·   CRL's datasets for Phase 1 have been provided to CSM for storage and
use by SMEs, researchers and for open access.

·    Phase 1 saw a total of 1,702 soil samples collected alongside 910
gravity survey points.

·    CRL continues work on Phase 2 to maximise the grant funding to
develop high-quality datasets that will benefit CRL's operations.

·    CRL is hosting local presentations this week, updating local
community members and landowners on the DDC data collected within the area,
and plans for Phase 2.

·    Phase 2 of the DDC data collection will see the completion of soil
sampling, targeting infill around soil and gravity anomalies and likely new
aerial and drone surveys to complement existing datasets.

Through DDC grant funding, CRL has used the Redmoor exploration license area
as a field laboratory for the collection of geochemical and geophysical data.
The results to date improve CRL's understanding of the granite body below the
license area and, when combined with the soil sampling results, highlight
significant mineral prospectivity in the wider license area. Further DDC
fieldwork is planned to test these results, helping CRL in identifying targets
for future exploration.

Phase 1 Soil Sampling - Fieldwork and Results

Using the method trialled in the close-spaces auger sampling in Target Tip
Valley ("TTV") (reported 28 September 2021), CRL conducted Phase 1 of the DDC
soil sampling campaign. Samples were initially planned on 400m spaced lines,
orientated perpendicular to the dominant mineralisation trends, with samples
spaced every 10m. Lines were modified to avoid infrastructure and to best fit
available land access. This survey is the highest detailed soil sampling
campaign completed within the area to date and significantly adds to the
understanding of the mineralisation present within CRL's license area.

CRL's field team collected 1,702 Phase 1 soil samples from August 2021 to
January 2022 (see Appendix A, Figure 2: Location Map). Samples were shipped to
ALS Minerals Loughrea and were analysed using method ICP-MS ME-MS89L, with a
Boron analysis add-on. Final sample results were received from the laboratory
in May 2022.

Soil samples were expected to contain lower overall metals content compared to
those around the Redmoor resource and TTV, due to the presence of
unmineralized geology overlying a large section of the sampling area. However,
following receipt and mapping of laboratory results, soil anomalies containing
significant metal content above background levels were noted with noticeable
trends across sample lines indicating the potential presence of mineralised
structures (see Appendix B, Table 1 which includes several highlights).

Following receipt of the soil sample results, a research project was
undertaken over a three-month period from June - August 2022. This project
included modelling and interpretation of the combined results of the gravity
survey and the soil sample results, and included knowledge of geology,
mineralisation styles of the area and combined data from previous studies, to
produce Minerals Prospectivity Maps ("MPM") of the Redmoor License area
(Figure 1).

 

Figure 1: Minerals Prospectivity Map of the Redmoor license area covered by
DDC soil samples. (A) Elevated Sn-W-Cu anomalies, (B) Elevated SN-W anomalies
and (C) Elevated SN-W-CU anomalies. A and B represent trends consistent with
the lode and SVS mineralisation at Redmoor, and C represents higher values
associated with two modelled granite upwellings ("MGU").

 

The MPM map shows areas of higher and lower prospectivity for mineralisation
(red are higher / blue are lower). Increased potential mineralisation has been
noted around the modelled granite upwellings and along two near East-West
trending zones, consistent with soil anomalies. These zones follow a similar
alignment to the lodes and sheeted vein systems ("SVS") found at and around
Redmoor. Zones A, B and C contain elevated Tin, Tungsten and Copper anomalies
in the soil samples collected.

Ground Gravity Survey - Fieldwork and Results

A ground-based gravity survey of the Redmoor area was completed by CRL field
staff over the period of August - December 2021. Reid Geophysics Ltd
supervised the collection of data and completed Quality Assurance/Quality
Control checks, and all modelling and interpretation of the results. Following
completion of the survey, Astute Geosciences, working with Reid Geophysics,
completed a 2D reinterpretation of the geology of the survey area,
reinterpreting several faults and indicating the likely presence of two
subsurface granite upwellings. In addition to interpretation and modelling the
gravity data, Reid Geophysics recently completed a 3D model interpretation of
the granite body below Redmoor and accompanying reports.

This new model is a significant improvement on the knowledge of the potential
size, shape, and nature of the granite body. The modelled presence of two
subsurface granite upwellings, when combined with the DDC soil sampling
results, highlights the potential for new mineralised systems to the west of
Redmoor (Figure 2) providing a favourable locale for mineralisation similar to
those known elsewhere in Cornwall. These will be investigated through further
exploration work programs.

Figure 2: shows the location of the soil samples in relation to the Redmoor
JORC (2012) compliant Resource (11.7mt @ 1.17% Sn (Eq)) and other examples of
historical mining. The newly modelled granite upwellings between Redmoor and
the soil samples suggest further potential for mineralising systems to the
west with the soil sampling results and MPM highlighting this potential. This
data will be available as a DDC data output

The granite model and associated reports are now available via the DDC Hub for
further research and use by SMEs. This model provides the DDC Hub with a
significant 3D model, with which to highlight the Hub's use as a geological
repository for the Southwest, an area highlighted by the UK Government's
Critical Minerals Strategy (published in July 2022) as a key location for
Critical Minerals and associated knowledge.

Following completion of Phase 1 of the research project in September 2022,
datasets and reports are now being made available via the DDC Hub, based on
the Penryn Campus at CSM. These will be available to SMEs, researchers and for
general access in line with the DDC data policy.

CRL is hosting local presentations, this week updating local community members
and landowners on the DDC data collected within the area, and plans for Phase
2 of the DDC project work.

Ongoing DDC Work Plan

CRL continues to progress the DDC fieldwork. Phase 2 of soil samples began in
June 2022, alongside the research project. The DDC budget allows for a total
of 2,500 soil samples to be taken and analysed, therefore Phase 2 will consist
of 798 soil samples. These samples will target soil anomalies and trends of
high minerals prospectivity highlighted above (Figure 2). Sampling is expected
to be complete shortly, with samples shipped to ALS Minerals Loughrea and
analysed before the end of the 2022. Results from Phase 2 will be used to
update the MPM model and to target future investigations.

CRL intends to complete drone-based surveys of a section of the license area
in Q1 and Q2 of 2023, and participate in a DDC-funded aerial survey, covering
DDC Partner areas of interest.

Planned Drilling

CRL continues preparation for a drill program, in the TTV, to test at depth
previously reported high-grade auger and trenching results (as reported 17
November 2021). A General Permitted Development Order application, for
necessary consents, was approved by Cornwall Council. Drilling has been
delayed into 2023 due to a shortage of available drill rigs. Drilling is
expected to consist of four drillholes, to test both the reported tin target
and the potential westward continuation of the Redmoor Sheeted Vein System
orebody.

Commenting, Peter Wale, Executive Director of Strategic Minerals and Director
of CRL, said:

"These DDC datasets provide welcome confirmation that mineralisation likely
continues to the west of Redmoor and the Target Tip Valley (TTV).
Historically, this area has been under-explored and unmined and provides
likely targets for further future investigation and exploration.

"CRL's experience at Redmoor has indicated that grades often increase
significantly at depth, as the source granite is approached. A new granite
model, developed from the DDC gravity survey, showing that the granite likely
rises closer to surface to the west of TTV is therefore encouraging and
provides the potential to expand on the existing resource for what the UK
Government now defines as Critical Minerals, such as Tin & Tungsten at
Redmoor.

"CRL intends to continue to maximise its DDC grant funding to produce
high-quality datasets that will increase confidence at Redmoor and that will
be available for others to research via the DDC Hub. We believe this data is a
good example of what can be achieved, through low-cost Government initiatives,
to de-risk exploration for Critical Minerals in the UK.

"The 2023 expected drill program will utilise the data produced in the DDC
datasets to pursue exploration of depth extensions of the TTV target and the
potential for a westward continuation of the existing Redmoor orebody."

Notes to Editors

Strategic Minerals plc:

 

Strategic Minerals plc is an AIM-quoted, profitable operating minerals company
actively developing projects tailored to materials expected to benefit from
strong demand in the future. It has an operation in the United States of
America along with development projects in the UK and Australia. The Company
is focused on utilising its operating cash flows, along with capital raisings,
to develop high quality projects aimed at supplying the metals and minerals
likely to be highly demanded in the future.

In September 2011, Strategic Minerals acquired the distribution rights to the
Cobre magnetite tailings dam project in New Mexico, USA, a cash-generating
asset, which it brought into production in 2012 and which continues to provide
a revenue stream for the Company. This operating revenue stream is utilised to
cover company overheads and invest in development projects aimed at supplying
the metals and minerals likely to be highly demanded in the future.

In May 2016, the Company entered into an agreement with New Age Exploration
Limited and, in February 2017, acquired 50% of the Redmoor Tin/Tungsten
project in Cornwall, UK. The bulk of the funds from the Company's investment
were utilised to complete a drilling programme that year. The drilling
programme resulted in a significant upgrade of the resource. This was followed
in 2018 with a 12-hole 2018 drilling programme has now been completed and the
resource update that resulted was announced in February 2019. In March 2019,
the Company entered into arrangements to acquire the balance of the Redmoor
Tin/Tungsten project which was settled on 24 July 2019 by way of a vendor loan
which was fully repaid on 26 June 2020.

In March 2018, the Company completed the acquisition of the Leigh Creek Copper
Mine situated in the copper rich belt of South Australia and brought the
project temporarily into production in April 2019. In July 2021, the project
was granted a conditional approval by the South Australian Government for a
Program for Environmental Protection and Rehabilitation (PEPR) in relation to
mining of its Paltridge North deposit and processing at the Mountain of Light
installation. In late June 2022, an updated PEPR, addressing the conditions
associated with the July 2021 approval, was approved.
