Savannah Resources
Plc
(AIM: SAV) ('Savannah', or
the 'Company')
Second phase of DFS drilling
underway at the Barroso Lithium Project
Savannah Resources Plc, the
developer of the Barroso Lithium Project (the 'Project') in
Portugal, Europe's largest spodumene lithium
deposit, is pleased to announce that it has
recommenced drilling as it moves towards the finalisation of the
Project's Definitive Feasibility Study ("DFS").
This second phase of the DFS drill
programme will include a total of 117 drillholes for approximately
13,000m split into c.9,000m of reverse circulation drilling and
c.4,000m of diamond drilling, and will cover resource,
metallurgical and geotechnical drilling at the Grandão,
Reservatório and Pinheiro deposits.
Highlights:
·
Contractors: Three drilling
contractors, all of which have worked on previous drilling
campaigns at the Project, have been engaged to provide 2 reverse
circulation and 2 diamond drill rigs to ensure rapid completion of
the work programme.
·
Drill pad
preparation: Preparations for the
drilling campaign began before Christmas and as of 7 January,
vegetation had been cleared for 64 drill pads, with 27 pads
constructed.
·
Resource
drilling: will target conversion of
all existing JORC Inferred Resources at the 3 deposits into at
least the Indicated category to allow for inclusion into the DFS
and potential conversion to JORC Reserves.
·
Metallurgical
drilling: will focus on the
high-grade lithium mineralisation at Pinheiro, which was identified
in the first phase of DFS drilling last year, and the second
Pinheiro pegmatite lens.
·
Geotechnical
drilling: will be focused on the
planned pit wall locations to complete final designs.
·
Assay
results: will be released when
received, which is expected to be from late Q1 2025
onwards.
·
Resource
Updates: for the Grandão, Reservatório and Pinheiro deposits
will be completed once results from the drilling are
available.
Savannah's CEO, Emanuel Proença,
said, "Following the award of the
temporary land access order in December, our technical team began
immediate preparation of the ground for the subsequent second phase
of DFS-related drilling. With numerous drill pads now constructed,
we are delighted to announce that drilling is back underway at the
Project.
"This is a substantial programme,
which will provide much of the outstanding data we need to upgrade
the Project's existing 28Mt JORC resources, as well as finalise pit
designs and other technical aspects of the Project. Furthermore, it
will generate significant news flow over the coming months, which
we look forward to sharing with the market."

Final Phase of DFS
Drilling
The drill programme will include a
total of 117 drillholes for 12,961m split into 8,980m of reverse
circulation drilling ('RC') and 3,981m of diamond drilling ('DD')
and include resource ('RSD'), metallurgical ('MET') and
geotechnical ('GEO') drilling at the Grandão ('GRA'), Reservatório
('RES') and Pinheiro ('PNR') deposits (Table 1 and Figure
3).

The Resource drilling (Table 2) was planned
internally by Savannah's technical team, with supervision from the
independent resource signatory. A total of 102 drillholes for
11,311m are planned to upgrade the Inferred Resources into the
Indicated and Measured categories which is required for their
inclusion into the DFS and conversion into JORC
Reserves.

The Metallurgical drilling (Table 3)
objective was adjusted following the conclusion of the last
drilling programme where a new high-grade zone of lithium
mineralisation was identified at Pinheiro. The additional works are
targeted at testing the metallurgical performance of this zone and
the second lens of the Pinheiro deposit, which to date has only
received limited work. A total of 3 drillholes, adding up to 250m
are planned to allow enough sample for the additional detailed
metallurgical testing to be completed for the DFS.

The Geotechnical drilling
(Table 4), which is
targeting the proposed walls of the open pits now consists of 12
drillholes, adding up to 1,400m. This should generate enough
samples for the geotechnical testing required for the final design
of the pits.

About Savannah
Savannah Resources is a mineral
resource development company and the sole owner of the Barroso
Lithium Project (the 'Project') in northern Portugal, the largest
battery grade spodumene lithium resource outlined to date in
Europe.
Through the Project, Savannah will
help Portugal to play an important role in providing a long-term,
locally sourced, lithium raw material supply for Europe's lithium
battery value chain. Once in operation the Project will produce
enough lithium (contained in c.190,000tpa of spodumene concentrate)
for approximately half a million vehicle battery packs per year,
and hence make a significant contribution towards the European
Commission's Critical Raw Material Act goal of a minimum 10% of
European endogenous lithium production from 2030. Savannah is being
supported in its development goals by its strategic partner and
largest shareholder AMG Critical Materials N.V., the global
critical materials business.
Savannah is focused on the
responsible development and operation of the Barroso Lithium
Project so that its impact on the environment is minimised and the
socio-economic benefits that it can bring to all its stakeholders
are maximised.
The Company is listed and regulated
on the London Stock Exchange's Alternative Investment Market (AIM)
and trades under the ticker "SAV".
