Andrada Mining
Company Overview
Andrada Mining Limited is an emerging African critical minerals producer focused on developing a portfolio of globally significant tin, lithium, tantalum, tungsten, and copper assets in Namibia's prolific Erongo region. The company's flagship Uis Mine, formerly the world's largest hard-rock open cast tin mine, has been successfully redeveloped into a multi-commodity operation producing tin and tantalum with pilot lithium production underway.
Andrada is uniquely positioned as the only tin producer listed on AIM (ATM) and OTCQB (ATMTF), with a JORC-compliant resource base of 135 million tonnes targeting expansion to 200 million tonnes. The operation benefits from Namibia's stable mining jurisdiction, which features supportive legislation, an educated workforce with 87.3% adult literacy, and world-class infrastructure including the Walvis Bay port located 230km from Uis.
Since production restart in 2019, Andrada has achieved consistent operational improvements, with the processing plant operating above nameplate capacity and delivering over 90% plant availability for the past two years. The company maintains strong community integration, with Namibian citizens comprising 99% of its workforce and achieving zero lost-time injury frequency rate since October 2024.
Opportunity
Andrada offers a compelling investment opportunity anchored by its position as the sole AIM-listed tin producer amid a structurally favorable market where prices surged 40% year-to-date in 2025, exceeding US$40,000 per tonne in December. The company's diversified critical minerals portfolio provides multiple revenue streams and risk mitigation, with established tin and tantalum production complemented by lithium development partnerships and copper-tungsten exploration upside.
The strategic earn-in agreement with SQM, the world's largest lithium producer, validates Lithium Ridge's potential, where SQM can acquire 50% ownership through US$40 million investment, demonstrating third-party confidence in Andrada's asset quality. Operational excellence is evidenced by consistent 73% tin recovery rates exceeding the 70% internal target for three consecutive quarters, while Q3 FY2026 contained tin production increased 10% year-on-year to 255 tonnes.
Namibia's Tier-1 mining jurisdiction status, characterized by democratic governance, independent legal systems, and 4.2% GDP growth, provides exceptional operating conditions. The company's ESG commitment aligns with international standards, creating sustainable value for stakeholders while positioning Andrada at the forefront of Africa's critical minerals supply chain.

Growth Strategy
Andrada is executing a multi-phase growth strategy focused on maximizing value from its existing operations while advancing development projects across its Namibian portfolio. The company is commissioning a new jig plant in H2 2025 to increase tin recovery and processing flexibility, with ore sorter installation planned to enhance pre-concentration efficiency and support lithium integration.
The Continuous Improvement 2 programme targets increasing tin production from current 1,200tpa nameplate capacity to 1,500tpa through operational optimization, having already delivered 12% year-on-year processing rate improvements to 146 tonnes per hour. Lithium development follows a dual-track approach: advancing petalite production from Uis through metallurgical testwork and offtake discussions, while accelerating spodumene exploration at Lithium Ridge through the SQM partnership, which has deployed a third drill rig to fast-track resource definition.
Brandberg West exploration is investigating high-grade tungsten and copper potential, with maiden drilling returning intersections up to 10.55% tin, 3.53% tungsten, and 2% copper. Third-party ore supply agreements, including the high-grade Goantagab agreement at 1.5% tin, complement organic growth and unlock regional expansion opportunities. This staged development approach, supported by strong market fundamentals and strategic partnerships, positions Andrada to deliver transformational growth across multiple critical minerals within achievable timelines.

Financial Overview
Andrada maintains a solid financial structure with 1.67 billion shares issued as of May 2025, supported by a diverse institutional shareholder base including The Orange Trust (15.57%), Naminco Limited (6.82%), and JLE Limited, which recently increased its stake to 7.7% from 5.0%. The June 2025 accelerated bookbuild raised USD 8 million at 3.00 pence per share, with USD 6 million allocated to ore sorter installation and jig plant ramp-up, demonstrating focused capital deployment toward growth initiatives.
The company benefits from a strong tin pricing environment, with prices up 40% year-to-date, while Q3 FY2026 operational performance showed 10% year-on-year growth in contained tin production to 255 tonnes and 25% quarter-on-quarter increase in shipments to 15. Recovery rates consistently exceed 70% targets at 73%, while plant availability and utilization maintain 90%+ levels, ensuring efficient asset deployment.
The SQM partnership provides non-dilutive development funding for Lithium Ridge, with USD 40 million potential investment for 50% ownership, validating asset value while preserving Andrada's balance sheet. With zero lost-time injuries since October 2024 and 99% Namibian workforce composition, the company demonstrates operational excellence and social license, creating a sustainable platform for long-term value creation as it advances toward 200 million tonne resource target and expanded production capacity.
Risk Factors and Mitigation
Andrada actively manages commodity price volatility through diversified exposure across five critical minerals, reducing single-commodity dependency while capitalizing on tin's 40% price surge and copper's 30% year-to-date increase. Operational risks are mitigated by proven processing methods delivering consistent 73% recovery rates, 90%+ plant availability, and an experienced management team with decades of African mining experience. Development funding requirements are addressed through the SQM partnership structure, which provides USD 40 million in staged investments for Lithium Ridge, while the June 2025 capital raise secured USD 8 million for near-term expansion projects.
Technical risks associated with lithium integration are derisked through pilot production, bulk sampling, and metallurgical testwork showing high recoverability rates exceeding 75% with saleable grades above 6.82% Li₂O. Permitting and regulatory risks are minimized in Namibia's mining-friendly jurisdiction, which features supportive legislation, democratic governance, and established mining infrastructure. Environmental and social risks are managed through robust ESG systems aligned with international standards, 99% local employment, and strong community engagement, ensuring sustainable development and stakeholder alignment.
