DESCRIPTION OF THE APPLICANT AND ITS ACTIVITIES:

Reveille’s strategy is focused on identifying and advancing uranium exploration opportunities in assets that have benefited from significant historical expenditure and technical work, but which may not have achieved full value realisation due to geopolitical, technological, financial, or historical factors. The Company intends to target projects with established geological potential and existing datasets, with a view to defining mineral resources in accordance with modern international reporting standards. While the Company’s initial focus is on historical uranium deposits in Europe, including Italy, Reveille will also evaluate opportunities in other western-aligned jurisdictions.

Reveille’s initial focus is on two historical uranium deposits in Lombardy, northern Italy, known as Novazza and Val Vedello, for which licence applications were submitted in 2025 and are held by its Italian subsidiary, Futuro Energetico Italiano Srl. Evidence of uranium mineralisation in north-west Italy was first identified as early as 1912. A more concerted exploration effort began in 1957, led by AGIP Nucleare, a subsidiary of Eni (Ente Nazionale Idrocarburi), as part of Italy’s national nuclear energy programme and concurrent with the construction of the country’s first nuclear power plants. The Novazza deposit was identified in 1959, with development commencing in the 1970s, while the Val Vedello deposit was discovered in 1975.

Underground mine development took place at both sites during the late 1970s before ceasing in 1979, with exploration activities continuing into the 1980s. However, these activities stalled following local environmental and safety concerns and ceased completely following the post-Chernobyl 1987 referendum.

Against a backdrop of increasing concerns regarding energy security and access to natural gas supplies from Russia and the Middle East, together with the growing recognition of nuclear energy as a source of low-carbon baseload electricity, European governments, including Italy, are demonstrating renewed interest in nuclear energy, particularly in the development of small modular reactor technologies. Concurrently, there is an increasing strategic focus on securing domestic and western-aligned sources of critical and strategic minerals, including uranium.
