Andrada Mining Limited

("Andrada" or the "Company")

New mineralised pegmatites identified at Lithium Ridge as exploration drilling
commences with SQM

Andrada Mining Limited (AIM: ATM, OTCQB: ATMTF), the critical minerals
producer with mining and exploration assets in Namibia, is pleased to announce
the commencement of exploration drilling at the Lithium Ridge project in
partnership with Sociedad Química y Minera de Chile SA through its subsidiary
SQM Australia (Pty) Ltd ("SQM"). (See announcement dated 9 September 2024 and
28 February 2025). This milestone represents part of the stage 1 workplan of
the three stage earn-in agreement with SQM. Under this first stage, SQM will
fund up to US$7 million in exploration to secure an initial 30% interest at
project level with the potential to fund up to US$40m million over the three
stages.

HIGHLIGHTS

·   14 000 metres of Orientated Diamond Drilling ("DD") underway across
priority lithium targets.

·   High resolution geological mapping and sampling already identifying new
pegmatites with visible spodumene mineralisation.

·   Programme builds on historical results of up to 2.13% Li₂O along a 6
km mineralised ridgeline.

Anthony Viljoen, Chief Executive Officer, commented:
"The commencement of drilling at Lithium Ridge with our tier-1 joint-venture partner, SQM, is a significant step forward in unlocking one of Namibia's most exciting lithium opportunities. The encouraging historical results of up to 2.13% Li₂O along the 6km ridge line, are already being complemented by a new geological mapping and sampling programme that has identified additional mineralised pegmatites containing visible spodumene crystals. This strengthens our confidence in the scale and quality of the project. The investment by SQM underscores Lithium Ridge's potential and Namibia's growing role in the global supply of critical minerals. We expect this programme to provide the foundation for fast-tracking the project towards development."
Lithium ridge exploration programme

The Lithium Ridge mining licence is located only 35 kilometres from Andrada's
producing Uis tin mine and hosts multiple high-priority lithium-bearing
pegmatites, with associated tin and tantalum credits.

The current programme is designed to:

·   Unlock the full potential of the mineralised ridge and,

·   Extend exploration across the wider licence area where new spodumene -
bearing pegmatites have been identified.

The 14 000 metre DD programme will comprise approximately 120 orientated
holes, to determine the depth extensions and continuity of the extensive
mineralisation already identified at surface. Historical work confirmed grades
of up to 2.13% Li₂O and metallurgical spodumene recoveries of up to 80%,
producing a premium 6.8% Li₂O concentrate with low iron levels. These
results were on drill chip samples produced during reverse circulation
drilling at Lithium Ridge. (See announcement dated 5 December 2023). This
programme is expected to significantly enhance the geological understanding of
Lithium Ridge and demonstrate its economic potential as a large-scale, high
quality lithium project.

About Andrada Mining Limited

Andrada Mining Limited, formerly Afritin Mining Limited, is a London-listed
technology metals mining company with a vision to create a portfolio of
globally significant, conflict-free, production and exploration assets. The
Company's flagship asset is the Uis Mine in Namibia, formerly the world's
largest hard-rock open cast tin mine and currently being re-developed as a
major tin-tantalum-lithium producer. An exploration drilling programme is
currently underway with the aim of expanding the tin resource over the
fourteen additional, historically mined pegmatites that occur within a 5km
radius of the current processing plant. The Company has set a mineral resource
target of 200 Mt to be delineated within the next 5 years. The existing mine,
together with its substantial mineral resource potential, allows the Company
to consider economies of scale. Andrada is managed by a board of directors
with broad industry knowledge and a management team with extensive commercial
and technical skills. Furthermore, the Company is committed to the sustainable
development of its operations and the growth of its business. This is
demonstrated by the way the leadership team places significant emphasis on
