Drill Programme Recommences at Munni Munni

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

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to report that its proposed joint venture partner, GreenTech Metals Limited (ASX: GRE) ("GreenTech"), has announced that the Phase 1 drill programme will be accelerated with the addition of a second drill rig at the Munni Munni Platinum-Palladium-Copper-Nickel Project, ("Munni Munni" or the "Project").

GreenTech and Alien are progressing the final administrative processes to enable conclusion of the transaction, and a further announcement will be made in due course.

Executive Chairman, Bruce Garlick, commented:

"The addition of a second drill rig underlines GreenTech's intent to move quickly at Munni Munni and to advance the Project through a modern, JORC (2012) compliant resource process. With the programme designed to validate historic resources, support metallurgical test work and test for potential extensions, and with GreenTech well funded following its December 2025 capital raising, we see a clear pathway to materially de-risk the asset through 2026. Alien will retain meaningful upside via its expected 30% free-carried interest to completion of a bankable feasibility study, and we look forward to updating the market as the final administrative processes are completed."

The full text of the announcement issued by GreenTech is provided below in Appendix A.

Appendix A - ASX: GRE ANNOUNCEMENT

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

Highlights

• Phase 1 drilling program which commenced in late 2025 is continuing at the recently acquired Munni Munni PGE Project in WA.
• A second drill rig has been mobilized to site to undertake the reverse circulation (RC) component of the Phase 1 program which will accelerate the program.
• The drill program underway is comprised of up to 20 holes for approximately 6,000m to provide QA/QC verification of historic resources to enable the Company to restate the Mineral Resource Estimate (MRE) in accordance with JORC (2012) in early 2026, potentially expand the resource outside of the existing mineralised envelope and obtain material for metallurgical test work.
• Logging and sampling of core is underway for new diamond drill holes and selected historical drill holes.
• The first batch of core samples is being prepared for dispatch to Perth for laboratory analysis.
• The company is well funded with $5.2 million raised in December 2025 to acquire the Munni Munni Project and to fund the forward exploration, resource evaluation, associated drilling and test work programs.
• The Munni Munni Project is situated on granted Mining Leases (MLs) with an historical non-compliant JORC (2004) 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 estimates 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).

GreenTech Metals Ltd (ASX: GRE) (GreenTech or the Company) is pleased to announce that the Phase 1 drill program will be accelerated with the addition of a second drill rig (Photo 1) at the recently acquired Munni Munni PGE Project3, located adjacent to the Company's advanced Whundo Copper-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.

The finalisation of the acquisition of a 70% interest[3] in this project, with provision to go to 80% was subject to shareholder approval which was received on 21 January 2026.

Non-Executive Chairman, Simon Kidston, commented:

"We are very pleased that a second drill rig has joined our Phase 1 drill program at Munni Munni to undertake the RC component of the program and to accelerate the program. This is a defining program 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 program is designed to transition Munni Munni into a modern, JORC (2012) compliant resource and position the Company for the next phase of technical and commercial evaluation to create value for our shareholders."

Phase 1 Drill Program:

The Phase 1 drill program comprises up to 20 Reverse Circulation (RC) / 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. The drilling will also test for mineralisation outside of the historical MRE as well as obtaining material for metallurgical test work.

To the extent possible within the program constraints the drilling will include infill and step-out coverage across the Ferguson Reef (Figure 1, 2), targeting both the historically defined higher-grade core within the 2002 MRE, 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 test work.

Due to the rugged nature of the terrain a small footprint track mounted drill rig has been chosen to undertake the core drilling component of the drill program (Photo 1). The drill program is anticipated to be completed in February 2026 with assay results anticipated approximately 4-6 weeks after completion.

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

Cautionary Statement[5] - 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).

*Notes: A. Undiluted resource using 1.9g/t (Pt + Pd + Au) lower cut-off

Maximum depth 800 metres

* Rh values were not included in the resource calculation, but estimated from extensive assay data, which showed the Rh grade is 6% of the Pd grade

Historical Drill Core

The historic core is in excellent condition with numerous ¼ and ½ core mineralised sections preserved which will be of great benefit to completing the QA/QC requirements for verification of the historical resource (Photo 2). The cataloguing of the historic core holes is underway along with logging and sampling of selected holes. The first batch of core samples is being prepared for dispatch to Perth for laboratory analysis.
