GreenTech Metals Acquires 70% of Munni Munni with 2.2 Moz Historical PGE Resource

A Strategic Acquisition in the Pilbara

GreenTech Metals Limited (ASX, GRE) has taken a significant step in expanding its footprint in Western Australia's mineral-rich Pilbara region by entering binding agreements to acquire a 70% interest in the Munni Munni Platinum Group Elements-Copper-Nickel (PGE-Cu-Ni) Project. This acquisition, with an option to increase to 80%, consolidates a substantial 346 km² land package adjacent to GreenTech’s existing Whundo Copper-Gold deposit, creating one of the largest contiguous tenement holdings in the West Pilbara district.

The Munni Munni project is notable for its historical high-grade PGE mineralisation, with a non-compliant JORC (2004) Mineral Resource Estimate of 24 million tonnes at 2.9 grams per tonne 4PGE, equating to approximately 2.2 million ounces. While this resource requires validation under current JORC (2012) standards, it provides a strong foundation for GreenTech’s planned exploration and development activities.

Unlocking Value Through Consolidation and Exploration

This acquisition marks the first time the Munni Munni layered mafic intrusion and surrounding prospective ground have been consolidated under a single operator, offering access to up to 21 kilometres of the Ferguson Reef; a key PGE-bearing stratiform horizon. Historical drilling, comprising nearly 400 holes and over 93,000 metres, has demonstrated continuity of mineralisation, with recent assays confirming shallow, high-grade PGE-Cu-Ni zones.

GreenTech plans to commence a drilling program imminently, targeting 20 holes to twin selected historic drill holes. This work aims to upgrade the historical resource to a JORC (2012) compliant Mineral Resource Estimate by early 2026, a critical step toward advancing the project’s development potential. The company’s strategy also includes resource expansion drilling, mining studies evaluating both open pit and underground scenarios, and additional exploration targeting copper-nickel anomalies along the intrusion’s eastern limb.

Market Timing and Strategic Synergies

The timing of this acquisition aligns with strengthening global demand and rising prices for platinum group elements, driven by their critical role in clean energy technologies and automotive catalysts. GreenTech’s Non-Executive Chairman Simon Kidston highlighted the opportunity to leverage these market dynamics alongside the project’s geological strengths and proximity to existing infrastructure.

Moreover, the consolidation of Munni Munni with the Whundo Copper-Gold deposit, located just 10 kilometres apart, offers potential synergies in future development and processing. The project’s location within a tier-1 mining jurisdiction, close to the regional centre of Karratha and existing mining infrastructure, further enhances its appeal.

Conditions and Next Steps

The acquisition is conditional upon GreenTech raising $3 million in capital, obtaining shareholder and regulatory approvals, and executing several supporting agreements. Upon completion, GreenTech will assume operatorship and issue consideration shares to the vendor, Alien Metals Limited. The vendor will be free-carried through to completion of a Bankable Feasibility Study, with GreenTech solely funding the joint venture.

In parallel, GreenTech has acquired two additional exploration tenements at Munni Munni South, further expanding its landholding and exploration potential in the region.

With drilling set to begin shortly and a clear pathway to resource validation, GreenTech Metals is positioning itself to capitalize on a multi-metal project with significant growth upside amid a favourable commodity price environment.
