ANGLESEY MINING PLC - Corporate Presentation September 2026

Anglesey Mining PLC’s September 2026 investor update outlined a renewed strategy to advance its 100%-owned Parys Mountain polymetallic project in North Wales following a significant corporate restructuring. The company has eliminated approximately £4m of legacy debt, established a new leadership team and raised more than £1m since December to progress one of the UK’s largest polymetallic resources. Parys Mountain hosts approximately 16.1Mt of mineralised material containing around 1% copper and 1.3% zinc, alongside lead, silver and gold, with management highlighting substantial exploration upside across the Northern Copper Zone and wider district. The growth strategy centres on three priorities: develop the mine, grow the resource and discover the district, supported by targeted drilling, updated resource modelling, metallurgical work and mine planning. Management is also progressing environmental and planning engagement, with an objective of securing consent within approximately two years, while building a pre-feasibility or feasibility-level body of technical work over the next 18 months. An internal review of the 2021 PEA indicated approximately threefold potential upside under updated commodity price assumptions, although further engineering and technical work is required to validate the investment case. With exposure to copper, zinc, lead, silver and gold, Anglesey Mining believes Parys Mountain is strategically positioned to support the UK’s critical minerals strategy while creating a commercially viable domestic mining operation and long-term shareholder value.
