BUSINESS update for the PERIOD ended 28 FEBRUARY 2026

Break-out quarter delivers record production performance, positive cashflow & funded growth pipeline

Andrada Mining Limited (AIM: ATM, OTCQB: ATMTF), a tin producer with a portfolio of critical minerals, mining and exploration assets in Namibia, is pleased to provide the following unaudited performance update for the quarter ("Q4 FY2026" or the "Quarter") and full year ended 28 February 2026 ("FY2026"). The Quarter concludes a transformational year in which the Company established strategic partnerships that fully fund the accelerated development of its broader portfolio of critical minerals.

Highlights

DIVERSIFIED ASSET PORTFOLIO

The Company has concluded several initiatives in the last Quarter that anchor long-term development and position the company for a strong growth trajectory over the coming financial year.

Brandberg West

§ Quarterly performance improved year-on-year ("YoY"), reflecting continued improvements in plant stability and throughput during a period of elevated tin prices:

§ Ore processed: increased by 5% to 255 320 tonnes (Q4 FY2025: 244 314 tonnes).

§ Processing rate: increased by 9% to 153 tph (Q4 FY2025: 141 tph).

§ Tin concentrate produced: increased by 20% to 453 tonnes (Q4 FY2025: 379 tonnes).

§ Contained tin produced: increased by 19% to 271 tonnes (Q4 FY2025: 228 tonnes).

Anthony Viljoen, Chief Executive Officer, commented:

"The fourth quarter has been a defining quarter for Andrada. We are delivering on our long-term strategy of consolidating highly prospective historic mining assets, attracting world class partners to accelerate their development, at a time of record commodity prices and immense strategic significance for our critical minerals portfolio.

The conclusion of the Brandberg West partnership with ACAM provides exposure to a high grade, tungsten mine with associated tin and copper credits. This comes at a time of record high prices for tungsten and a strong support for these sustained price levels. The geological work undertaken this Quarter at Lithium Ridge, building on the initial drilling results, indicates that Lithium Ridge could emerge as a significant lithium discovery. The accelerated drilling programme in partnership with SQM, will allow for rapid realisation of the inherent potential in this deposit.

At Uis, the Company delivered record operational performance and positive free cash flows providing a solid foundation for growth and the scaling of production over the coming year. Tin concentrate production increased by 20% year-on-year, reflecting continued operational improvements and supporting cash flow generation across the Group. The extension of our long-standing partnership with our tin off taker, Thaisarco, as well as the injection of capital from the European Investment Bank's technical assistance facility for the integration of the lithium processing circuit, further adds value as we scale production at Uis.

Commodity prices remained supportive during the period, with tin and tungsten doubling and trebling in prices year-on-year, respectively. We are pleased that Andrada enters FY2027 with institutional backing from world-class partners, and de-risked growth pipeline. We have built the operational track record and institutional partnerships necessary to deliver sustained value creation."

Brandberg West Overview

The Company concluded a USD51 million investment and funding partnership with ACAM LP, through its affiliate BWCAM Limited ("BWCAM"), and completed the associated conditions precedent during the Quarter. Historical drilling results recorded continuation of significant high-grade intersections at Brandberg West with reported grades as high as 10.55% for tin, 3.53% for tungsten and 1.95% for copper, demonstrating untapped value at this asset. (See announcements dated 12 September 2024 & 16 October 2024).

The initial USD10 million (£7.3 million) investment from BWCAM was received during the Quarter to initiate investigations on tailings recovery potential, feasibility study preparation and pit optimisation. The joint project team, representing Andrada and BWCAM, has finalised the workplan and execution of initial stage workstreams has commenced. (See announcements dated 21 January 2026 & 4 February 2026).

Lithium Ridge overview

Initial drilling results at Lithium Ridge, undertaken as part of Stage 1 of the earn-in agreement with Sociedad Química y Minera de Chile S.A. through its subsidiary SQM Australia (Pty) Ltd ("SQM"), confirmed high-grade lithium mineralisation of up to 3.02% Li₂O, alongside tin and tantalum mineralisation. (See announcement dated 9 February 2026). The presence of meaningful tin and tantalum grades alongside the lithium mineralisation emphasises the polymetallic nature of the asset and its capacity to deliver by-product credits that could enhance future project economics. These results reinforce Lithium Ridge's potential to evolve into a large-scale, long-life asset. (See announcement dated 26 January 2026).

Fourth Quarter Operational Performance (Q4 FY2026)

Solid performance during the Quarter compared to the prior corresponding period was driven by improvements across throughput, feed grade and recovery. Ore processed increased by 5% to 255 320 tonnes (Q4 FY2025: 244 314 tonnes), while feed grade improved by 9% to 0.146% tin (Q4 FY2025: 0.134% tin). In addition, the processing rate increased by 9% to 153 tph (Q4 FY2025: 141 tph), and tin recovery improved to 73% (Q4 FY2025: 70%), reflecting the cumulative impact of ongoing optimisation initiatives. These combined improvements resulted in a 20% increase in tin concentrate production to 453 tonnes (Q4 FY2025: 379 tonnes) and a 19% increase in contained tin production to 271 tonnes (Q4 FY2025: 228 tonnes).

The Company prioritised tin production over tantalum recovery in response to prevailing elevated tin prices, with the objective of maximising near-term revenue while maintaining operational flexibility. Tin prices reached approximately USD55 000 per tonne¹ towards the end of the financial year, which, together with increased production and continued cost optimisation, is expected to support positive cash flow generation.

Full-Year Operational Review (FY2026)

The strong quarterly performance translated into higher annual production, with ore processed increasing to 1 042 299t (FY2025: 965 058t). The full year performance improved across key operational parameters:

§ Processing rate increased by 7% to 146 tph (FY2025: 136 tph).

§ Tin concentrate production increased by 15% to 1 740 tonnes (FY2025: 1 507 tonnes).

§ Contained tin production increased by 11% to 1 036 tonnes (FY2025: 932 tonnes), supported by higher ore throughput and improved recovery.

§ Recovery rate remained stable at 72%, exceeding the Company's internal target of 70%.

Commissioning of the jig processing plant has been completed and is being currently utilised as a pre-concentrator to the primary tin processing plant. Full operational functionality will be realised when there is a resolution on the ore supply agreement.

European Investment Bank Partnership

UTMC entered into a Cooperation Agreement with the European Investment Bank to support the feasibility study for the Uis lithium integration project. Under the agreement, UTMC has access to up to EUR2 million, non-dilutive funding for technical and project development assistance. The work programme is focused on advancing the project towards bankable feasibility. (See announcement dated 10 February 2026).

Thaisarco Tin Offtake Agreement

UTMC has enhanced its existing tin offtake agreement with Thailand Smelting & Refining Co. Ltd ("Thaisarco") to include an exclusive tin supply arrangement. As part of the revised terms, Thaisarco advanced an unsecured USD3 million prepayment. The amount is non-interest-bearing and is repayable against future deliveries at the discretion of UTMC. The revised structure provides additional flexibility within the Company's working capital cycle while reinforcing the long-standing commercial relationship. (See announcement dated 24 February 2026).
