12-Month Work Programme to Advance Georgina IOCG Targets

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to provide its 12-month exploration work programme for the Company's 100%-owned Georgina Basin Iron-Oxide Copper-Gold ("IOCG") Project in the Northern Territory, Australia (the "Project"), further to the Company's announcement of 16 July 2026.

Highlights:

Vince Fayad, Chief Executive Officer of Alien Metals, said:

"Alien has completed three transactions since early 2025 as part of its strategy to advance and crystallise value from its diversified metals portfolio. The completion of the Georgina Basin IOCG acquisition, together with the further strengthening of Alien's Board, management and technical capability, marks the beginning of a new phase for the Company. Our immediate priority is to apply a disciplined and commercially focused approach to the portfolio by advancing high-impact opportunities, allocating capital selectively, working with experienced partners and seeking to crystallise value where appropriate.

"The Georgina project provides Alien with a substantial copper-gold exploration opportunity supported by significant prior exploration expenditure, an extensive technical dataset, more than 90 conceptual IOCG targets and three advanced prospects. Our 12-month programme is designed to systematically assess and rank these targets, refine the highest-priority anomalies and establish a technically robust pipeline of drill-ready opportunities while preserving capital.

"At the same time, the Company retains meaningful exposure to iron ore, silver, copper and platinum-group metals through its wholly owned assets, joint ventures and listed equity interests. We intend to assess each asset on its merits and pursue the pathway that offers the strongest risk-adjusted outcome for shareholders."

Overview

The Company intends to systematically advance the Georgina Basin IOCG Project, commencing with a comprehensive technical review and Project-wide ranking of the identified prospects and targets, including those identified by international resources consulting group SRK Consulting. This work will inform the prioritisation of subsequent field exploration and potential drilling.

The prospects across the Project are at various stages of technical advancement. While Leichhardt East, Leichhardt West and Banks are considered drill-ready (see Figure 1), other targets require targeted geophysical surveys or additional modelling to refine their scale, geometry and priority. Certain exploration licence applications will also require engagement with Traditional Owners before the tenure can progress towards grant. Potential external funding opportunities that may be available include the BHP Xplor programme and Northern Territory Government exploration co-funding grants.

The 12-month work programme has been designed to align with the November-to-March wet season, preserve capital and generate a systematically ranked pipeline of high-quality targets for potential future drill testing.

Key Targets

The three advanced targets comprise the Leichhardt East, Leichhardt West and Banks prospects. Previous drilling at these prospects returned geochemical anomalism, including reported uranium values of up to 0.23% U₃O₈, elevated copper over broad intervals and the IOCG pathfinder elements bismuth and silver (see the Company's announcement of 7 July 2026). These geochemical anomalies are associated with strong, unexplained gravity anomalies that indicate the presence of dense subsurface rocks considered prospective for IOCG-style mineralisation.

The Ranken Project is located in the eastern part of the Georgina Basin Project and is interpreted to contain geological units comparable to those hosting the world-class Mount Isa copper and lead-zinc-silver deposits. Recent drilling by Teck in the surrounding region targeted sediment-hosted base-metal mineralisation, and the associated technical reports have recently become publicly available. The Company will review these results and incorporate any relevant findings into its exploration planning for Ranken.

Exploration Licence Application 32284 (Figure 3) is interpreted to contain rocks of the Warramunga Formation, which hosts high-grade gold and copper deposits in the Tennant Creek Mineral Field. SRK Consulting has also identified multiple zones of magnetic alteration, interpreted fluid pathways and associated gravity-high anomalies within the area. The Company intends to commence engagement with the relevant Traditional Owners regarding an access agreement to facilitate future exploration, subject to the grant of the licence and receipt of all required approvals.

Exploration Funding Opportunities

The Company intends to apply for two potential external funding programmes: BHP Xplor and the Northern Territory Government's exploration co-funding grants.

BHP Xplor is a global accelerator programme operated by BHP that supports selected early-stage mineral exploration companies. Successful applicants may receive equity-free funding of up to US$500,000, together with mentoring and technical support from BHP specialists.

Through its Resourcing the Territory programme, the Northern Territory Government provides co-funding grants to successful applicants for eligible geophysical surveys and exploration drilling. Grants may fund up to 50% of eligible programme costs, subject to a maximum grant of A$150,000, with the remaining costs funded by the applicant.

The Company believes that elements of the Georgina Basin work programme may be eligible for partial funding through [both] these programmes and intends to submit applications to both BHP Xplor and the Northern Territory Government.

Next Steps

The Company has commenced a project-wide review and ranking of the Georgina Basin prospects, from early-stage opportunities through to the three advanced targets. The planned programme includes geophysical modelling, targeted gravity surveys, the review of recently released third-party exploration data and engagement with Traditional Owners regarding exploration licence applications over Aboriginal freehold land.

The body of work outlined above is expected to total approximately A$300k (approximately £155k) and will be funded from the Company's existing cash resources. This cost includes 100% of the monthly fixed retainer to Venari Minerals.

By June 2027 the Company expects to have completed a full technical review of 90+ conceptual exploration targets, sufficient additional gravity surveying and geophysical modelling to have a number of advanced exploration targets, as well as a pipeline of lower-order prospects. All prospects and targets will be ranked in order to determine the next phase of exploration, including the priority and timing of potential drilling.
