About Anglesey Mining plc

Anglesey Mining plc is a UK-based mineral exploration and development company. It owns 100% of the Parys Mountain copper-zinc-lead-silver-gold project on Anglesey, North Wales.

Parys Mountain is now the company's one remaining key asset, which gives LSE:AYM a clear and concentrated focus on expanding the resource and advancing plans for a mine.

New Chief Executive

Andrew Fulton, a Chartered Mining Engineer with more than 30 years of experience, joined the board as Chief Executive. His priorities include team formation, due diligence, turnaround and growth.

The appointment forms part of a board refresh announced on 6 May 2026 to support a change in strategic direction.

Low-Cost Exploration Tools

The Satellite Applications Catapult at Harwell is carrying out a preliminary satellite-based study to identify possible extensions, estimated to take about eight weeks.

A first phase of a drone-operated aeromagnetic survey is complete, and initial results suggest extensions along the flight paths with anomalies similar to those linked to known mineralisation at Parys Mountain.

Balance Sheet Simplified

On 25 February 2026 the company eliminated £4.0 million of Debt in exchange for its holdings in LIM and Grangesberg, leaving about £100,000 of debt after the restructuring.

A placing and subscription raised £680,000 at 6p per share on 9 March 2026, with one-for-one warrants at 7p valid until 2 March 2027.

Shareholder Support

Largest Shareholder Energold Minerals, which holds 24.4%, invested £350,000 through a Warrant exercise at 7.6p on 11 December 2025.

The company has also appointed Yellow Jersey PR as its financial and media relations agency to share news more promptly.

Why UK Copper Matters

Copper is central to electrification, renewable energy and grid expansion, and domestic supply chains for critical metals have received growing policy attention.

A UK-based project with multiple metals in a single deposit offers an interesting angle on that theme.

Key Factors to Monitor

Investors may follow the results of the satellite and aeromagnetic programmes, any follow-up ground exploration and updates on resource growth.

Copper Demand trends and progress towards mine planning will remain important themes.

Conclusion

Anglesey Mining plc's 11.76% advance on 11 Nov 2026 reflects interest in its refreshed strategy, simplified balance sheet and focus on Parys Mountain.

With a new Chief Executive, modern exploration tools and a clear resource-growth plan, LSE:AYM has several developments to follow. Exploration results and further corporate updates are the next items to watch.
