Notes to Editors

Reveille Resources plc (AQSE: REV; OTCID: RVREF) is a UK natural resources exploration and development company with a primary focus on Italy, where it is advancing the exploration and development of the country's largest historic uranium deposits.

Through its Italian subsidiary, Futuro Energetico Italiano S.r.l, the Company has submitted exploration-licence applications in respect of the Novazza and Val Vedello uranium projects in northern Italy, each of which is subject to the applicable environmental-assessment process. The projects were historically explored and developed by AGIP Nucleare S.p.A. and its operating subsidiary, SOMIREN, both part of the ENI group, during Italy's national nuclear programme between 1959 and 1983. This work included more than 87,000 metres of historical drilling and approximately 17 kilometres of underground development.

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 jurisdictions where 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.
