Ippolito Ingo Cattaneo, Executive Director of Reveille, commented:

"We are delighted to be admitted to the Aquis Growth Market following a successful IPO fundraising, demonstrating strong investor confidence in Reveille's value potential and the opportunity presented by the Novazza and Val Vedello uranium deposits at a time when Italy is actively reconsidering the role of nuclear energy in its future energy mix. The successful fundraising provides the Company with a solid foundation from which to pursue its strategic objectives.

The Novazza and Val Vedello uranium deposits represent one of Europe's most significant historical uranium districts. Collectively, they have benefited from more than 87,000 metres of historical drilling, approximately 17 kilometres of underground development, and what the Board believes would equate to hundreds of millions of euros of exploration and development expenditure if replicated today. Historical estimates indicate the deposits contain approximately 15 million pounds of U₃O₈, representing an illustrative in-situ metal value of approximately US$1.2 billion based on current uranium prices. This historical work provides an invaluable technical foundation from which to advance the projects using modern exploration techniques and internationally recognised reporting standards.

Our Board is comprised entirely of Italian nationals with a clear understanding of Italy's political, regulatory and energy landscape. A unique convergence of factors presents an unprecedented opportunity to materially advance the Novazza and Val Vedello uranium deposits for the first time since their original discovery and development during the twentieth century. Heightened geopolitical uncertainty, increasing concerns over European energy security, the accelerating drive towards decarbonisation and the growing recognition of nuclear energy as a reliable source of low-carbon baseload power have fundamentally reshaped the strategic importance of uranium globally. In Italy, for the first time in almost four decades, nuclear energy is once again being actively considered as part of the country's long-term energy strategy, with Parliament progressing legislation to establish a new legal framework for the possible reintroduction of sustainable nuclear power.

While these developments provide a favourable backdrop, the Company's exploration strategy is not dependent upon the outcome of Italy's domestic energy policy. As is common in other jurisdictions, including Australia and Canada, uranium exploration and resource definition can be undertaken independently of domestic nuclear generation policy. Our immediate focus is on advancing the Novazza and Val Vedello exploration licence applications through the Environmental Impact Assessment (VIA) process, securing the necessary regulatory approvals and applying modern exploration techniques to further evaluate these historically significant uranium deposits.

The successful development of strategically important projects requires the confidence and participation of all stakeholders. We are committed to engaging openly and constructively with local communities, regional authorities and national institutions throughout the permitting and exploration process, ensuring that exploration activities are undertaken responsibly, transparently and with minimal environmental impact. We believe that this approach, underpinned by technical excellence, environmental stewardship and meaningful stakeholder engagement, will create lasting value for local communities, our shareholders and Italy's long-term strategic interests, while preserving the natural environment for future generations.

The Company looks forward to updating shareholders as the Novazza and Val Vedello exploration licence applications progress through the Environmental Impact Assessment (VIA) process and, subject to the necessary regulatory approvals, to commencing a new phase of modern exploration. The objective is to establish Novazza and Val Vedello as one of Europe's most significant uranium exploration opportunities."

Notes to Editors

Reveille Resources plc (AQSE: REV) is an Italy-focused uranium exploration and development company established to unlock the value of the country's historic uranium deposits.

The Company's principal assets are the Novazza and Val Vedello uranium deposits in northern Italy, which together represent one of Europe's most significant historical uranium districts. Collectively, the projects have benefited from more than 87,000 metres of historical drilling, approximately 17 kilometres of underground mine development, and what the Board believes would equate to hundreds of millions of euros of exploration and development expenditure if replicated today. Historical estimates for the Novazza and Val Vedello deposits indicate a combined inventory of approximately 15 million pounds of U₃O₈. These estimates are historical in nature and are not reported in accordance with any current internationally recognised mineral resource reporting standard.

Reveille's strategy is to identify and advance uranium projects that have benefited from substantial historical exploration and technical work but where value has yet to be fully realised due to geopolitical, technological, financial or historical factors. By applying modern exploration techniques and internationally recognised reporting standards, the Company intends to verify historical data, advance exploration and work towards the delineation of mineral resources in accordance with internationally recognised reporting standards.

While Italy remains the Company's principal area of focus, Reveille will selectively evaluate additional uranium opportunities elsewhere in Europe and in other western-aligned jurisdictions where the Board believes similar value creation opportunities exist. The Company is committed to advancing its projects responsibly, working closely with local communities, regulators and other stakeholders to ensure that exploration activities are undertaken to the highest environmental, technical and governance standards.
