"First Development Resources' admission to AIM comes at a time when the world needs more critical, precious-and base-metals. This presents an exciting opportunity for a company such as ours with ownership of four diverse exploration and development assets located within one of the world's most attractive mining jurisdictions.  We believe FDR represents significant potential and are eager to accelerate both exploration and corporate development activities immediately following our listing.

I would like to extend my sincere thanks to the entire FDR team and our shareholders for their support as we navigated the detailed exploration and corporate steps that have brought us to this point. Their commitment has been instrumental in positioning the Company for future growth and value creation. I would like to take this opportunity to welcome our new investors and we now look forward to advancing and executing our operational work programmes."

OVERVIEW OF FIRST DEVELOPMENT RESOURCES

First Development Resources' assets comprise eight granted tenements covering a total area of 2,314.4km². Five of the tenements, comprising three prospective copper-gold projects, are located in Western Australia (WA) while the remaining three tenements, comprising a rare-earth element (REE), uranium, lithium and gold project, are located in the Australian's Northern Territory. All tenements are wholly owned by FDR.

The WA Projects include the Company's flagship Wallal Project as well as Ripon Hills and Braeside West Projects situated in the Paterson Province, which is widely regarded as one of the most productive regions in Australia for the discovery of world-class gold-copper deposits, and which is home to several world-class mines and more recent discoveries.

The Selta Project in the Northern Territory is located in an area considered highly prospective for uranium and rare-earth element mineralisation along with base and precious metal mineralisation. Numerous companies are actively exploring within the region.

Beyond the existing portfolio, FDR is actively looking to expand its portfolio through the acquisition of early-stage exploration projects in Australia.

Location

Well-endowed with natural resources, Australia is a globally significant producer of more than 20 mineral commodities including bauxite, cobalt, gold, lithium, iron ore, mineral sands, nickel and rare-earth elements ("REEs"). Australia's resource and energy commodity exports are forecast to be worth AU$387B in FY 24-25. (Office of the Chief Economist, Australian Department of Industry, Innovation and Science, March 2025).

In 2024, Australia had around 350 operating mines producing 26 major and minor mineral commodities. Mining accounts for approximately two-thirds of Australia's total merchandise exports, with the combined energy and mineral commodity exports forecast to be worth AU$387B in 2024-25.

Projects with Critical and High-Demand Minerals

First Development's principal focus is to undertake exploration primarily for copper and gold in Western Australia and for REE's, lithium and uranium in the Northern Territory. The FDR Board believe the Projects give the Company exposure to the traditional precious metals market as well as capitalising on the emerging green metals markets.

FDR's Wallal Project comprises three granted exploration licences covering a combined area of 572.9 km² and located approximately 240km east of Port Hedland on the western edge of the Paterson Province, WA. Three copper-gold exploration targets have been defined at the Project using geophysical surveying, and are known as the Eastern, Border and Western anomalies. The primary styles of mineralisation being targeted by FDR are intrusive-related breccia hosted copper gold mineralisation systems. The Company expects to commence its Phase I Diamond Drilling Programme in the coming weeks to test the Eastern anomaly.

FDR's Selta Project comprises three granted ELs covering approximately 1,575km², which are considered prospective for lithium, REE, uranium, gold and potentially base metal mineralisation. Based on small field reconnaissance programs in 2022 and 2023, as well as in-depth desktop reviews of publicly available exploration data, FDR has identified nine prospective target areas. FDR proposes to initially explore four target areas considered to have the highest exploration potential. Planned works include soil and rock geochemical sampling, mapping and a geophysical survey (magnetics). Systematic, methodical, first-pass exploration is expected to commence later this year.

Management Team & Strategy

The members of the Company's Board have deep expertise in mining and mine development, considerable knowledge of the Australia mining sector, as well as expertise in corporate finance, legal and regulatory issues, ecology and the environment.

The Directors believe the establishment of a UK-based, Australian-focused AIM-quoted company creates the opportunity to generate shareholder value through the process of discovering and advancing new mineral deposits with a focus on copper-gold and uranium - rare-earth elements in Australia.

First Development's mineral assets are currently in the early-stage exploration phase, so whilst this means that they are highly risky, exploration success and progressing one or more of the Projects into the development phase could add significantly to their value.
