Notes to Editors

Alien Metals Ltd is a mining exploration and development company listed on the AIM market of the London Stock Exchange (AIM: UFO). The Company follows a balanced strategy of advancing and strengthening its asset portfolio through targeted technical work and project development, while evaluating partnerships, joint ventures, and selective monetisation opportunities that are value-enhancing for shareholders. At the same time, Alien will continue to consider opportunities to expand our asset base through carefully selected acquisition opportunities which meet the Board's prudent criteria.

Alien's principal focus is the advancement and development of its 90%-owned Hancock Iron Ore Project in the central Pilbara region of Western Australia. The Hancock tenements contain a JORC-compliant resource of 8.4Mt at 60% Fe and offer significant exploration upside, which is targeted to deliver a mining operation of 2Mtpa for 10 years. The Project benefits from direct access to the Great Northern Highway, providing a route to export facilities at Port Hedland, one of the world's largest iron ore export hubs. Alien also holds exploration interests in the Brockman and Vivash iron ore projects in the West Pilbara.

Alien additionally retains exposure to two advanced precious and base metal assets in the Pilbara. At Munni Munni, one of Australia's largest PGM systems hosting a historic resource of 2.2Moz PGM (Palladium, Platinum, and Rhodium) and gold, the Company has entered into a conditional joint venture with GreenTech Metals Ltd, under which Alien will retain a 30% interest, free carried to the completion of a bankable feasibility study. Alien also retains a 30% interest in the Elizabeth Hill Silver Project through a joint venture with West Coast Silver Limited, which encompasses Elizabeth Hill Mining Lease and exploration tenements surrounding the historical silver mine, which has produced some of Australia's highest-grade silver ore during the late 1990s.

Appendix A - ASX: GRE ANNOUNCEMENT

Drill Programme Recommences at Munni Munni PGE-Cu-Ni Project, WA

Highlights

·    Phase 1 drilling programme has recommenced at the Munni Munni Platinum-Palladium-Copper-Nickel Project in WA, following the festive season break.

·    The Munni Munni Project is situated on granted Mining Leases (MLs) with a historical JORC (2004) Mineral Resource Estimate (MRE) of 24 Mt @ 2.9 g/t 4E (PGE + Au) for 2.2Moz (HLX, 2002)[1]. This resource was historically defined in the period 1985-2002 with 91,077m of drilling comprising 328 drill holes.

·    Cautionary Statement^[2] - The estimates are historical and are not reported in accordance with the JORC Code (2012); a competent person has not done sufficient work to classify the historical estimates as mineral resources or ore reserves in accordance with the JORC Code (2012); and it is uncertain that following evaluation and/or further exploration work that the historical estimates will be able to be reported as mineral resources or ore reserves in accordance with the JORC Code (2012).

·    The planned Phase 1 drill programme comprises up to 20 holes for approximately 6,000m to provide QA/QC verification of historic resources to enable the Company to restate the MRE in accordance with JORC (2012) in early 2026, potentially expand the resource outside of the existing mineralised envelope and obtain material for metallurgical testwork.

·     The diamond coring portion of the programme commenced in late December 2025 with 8 drill holes to be completed for ~2,000m.

·     A second drill rig will commence the RC portion of the drill programme (~4,000m) in the coming days.

·    There is excellent preservation of the stored historical core along with related laboratory sample pulps, which can potentially be used to accelerate the QA/QC validation of the historical resource.

·    Strengthening PGE and copper prices, combined with the consolidation of the nearby Whundo copper project, has the potential to enhance project economics and provide a clear catalyst to re-evaluate Munni Munni's established PGE-Cu-Ni endowment.

GreenTech Metals Ltd (ASX: GRE) (GreenTech or the Company) is pleased to announce that, following the festive season break, the Phase 1 drill programme has recommenced at the Munni Munni Platinum-Palladium-Copper-Nickel Project located adjacent to the Company's advanced Whundo Copper-Zinc-Gold Project. The consolidation of these projects creates potential for an emerging district-scale multi-commodity development hub in the West Pilbara region of Western Australia.

Drilling, which had commenced in December, was paused for the festive season on 20 December with 162m completed on the first drill hole.

The finalisation of the acquisition of a 70% interest¹ in this project, with provision to go to 80% is subject to shareholder approval on 21 January 2026.

Non-Executive Chairman, Simon Kidston, commented:

"We are very pleased that our Phase 1 drill programme at Munni Munni has quickly recommenced and with a second drill rig engaged to accelerate the programme. This is a defining programme for GreenTech with the key objective of unlocking the full potential of this world-class PGE-Cu-Ni project.

"With strong global demand for PGEs, improving metal prices and district-scale consolidation achieved (subject to shareholder approval in January 2026), this programme is designed to transition Munni Munni into a modern, JORC (2012) resource and position the Company for the next phase of technical and commercial evaluation to create value for our shareholders."

Phase 1 Drill Programme:

The Phase 1 drill programme of up to 20 drill holes will comprise a combination of Reverse Circulation (RC) and Diamond Drill (DD) holes for approximately 6,000m to provide QA/QC verification of the historic modelled resource sufficient to enable a classification of the MRE to JORC (2012) standard in early 2026.

To the extent possible within the programme constraints, the drilling will include infill and step-out coverage across the Ferguson Reef (Error! Reference source not found.), targeting both the historically defined higher-grade core within the 2002 MRE[3], extensions along strike and assessing the potential for additional shallow copper-nickel outside the current resource footprint. Intervals of the diamond cored mineralisation will be selected for detailed geological, mineralogical and structural analysis. In addition, representative composite samples will be selected and prepared for metallurgical testwork.

Due to the rugged terrain, small footprint track-mounted drill rigs have been chosen to undertake both the core and RC drilling components of the drill programme. The drill programme is anticipated to be completed in February 2026, with assay results anticipated approximately 4-6 weeks after completion.

Historical Drill Core

There is excellent preservation of the stored historical drill core (Error! Reference source not found.) along with related laboratory sample pulps, which are located on site at Munni Munni. The cataloguing of the core and pulp samples is continuing. The numerous ¼ and ½ core mineralised sections preserved will be of great benefit to completing the QA/QC requirements for verification of the historical resource and may potentially enable acceleration of the QA/QC validation process.

About The Munni Munni PGE-Cu-Ni Project

The Munni Munni Project is one of Australia's most significant platinum group element (PGE) intrusions, hosting a large, laterally continuous reef containing platinum, palladium, rhodium and gold. The project has an extensive exploration history and several key attributes:

•   Well-established PGE-Cu-Ni endowment: Historic drilling and metallurgical work have confirmed strong grades within the Ferguson Reef, one of Australia's largest layered PGE-bearing systems.

•   Previous development activity: Multiple operators advanced the project through substantial drilling, testwork and resource modelling. Earlier development stalled mainly due to weaker PGE prices at the time.

•   Conventional processing pathway: Historical studies indicate the mineralisation responds well to traditional flotation and concentration techniques.

•   Significant growth potential: Mineralisation remains open along strike and at depth, with modern geophysics and drilling across the now-consolidated tenure expected to unlock additional high-grade zones.

•   Tier-1 mining jurisdiction: Located in the Pilbara region of Western Australia on a granted mining lease, with proximity to the Radio Hill processing facility (third-party owned; GRE has no current agreement in place

The consolidation of the surrounding land into a single 346.4km² contiguous package provides a strategic opportunity for district-scale exploration. The package covers a substantial portion of the Munni Munni intrusion and associated fault systems, which are prospective for both expansion of the known PGE-Cu-Ni Reef and the discovery of additional PGE sulphide targets along parallel structural corridors.
