GreenTech Acquires 70% of Munni Munni Project Covering 500km² with 6,000m Drilling Underway

A Strategic Acquisition in a Tier-1 Jurisdiction

GreenTech Metals Limited (ASX – GRE) has taken a decisive step forward in its growth strategy by completing the acquisition of a 70% interest in the Munni Munni Platinum-Palladium-Copper-Nickel Project, with an option to increase to 80%. Located in Western Australia’s prolific West Pilbara region, this project sits adjacent to GreenTech’s existing Whundo Copper-Gold deposit, consolidating a substantial landholding of over 500 square kilometres.

The acquisition is notable not only for its scale but also for the quality of the asset. Munni Munni is recognised as one of Australia’s most significant platinum group element (PGE) intrusions, hosting a laterally continuous reef system rich in platinum, palladium, rhodium, and gold, alongside copper and nickel. The project’s granted mining leases and exploration tenements provide a solid platform for exploration and development in a jurisdiction known for its mining-friendly environment.

Unlocking Historical Potential with Modern Exploration

Historically, the Munni Munni Project was explored extensively between 1985 and 2002, resulting in a JORC (2004) Mineral Resource Estimate of 24 million tonnes at 2.9 grams per tonne 4PGE, equating to approximately 2.2 million ounces. However, these estimates are considered historical and require verification and reclassification under the current JORC (2012) code.

To this end, GreenTech has initiated a Phase 1 drilling program comprising 6,000 metres of combined reverse circulation and diamond drilling. This program aims to provide quality assurance and control verification of the historic resource, with the goal of restating the Mineral Resource Estimate in early 2026. There is also potential to expand the resource beyond the known mineralised envelope and to collect samples for metallurgical test work, which will be critical for assessing processing pathways.

Market Dynamics and Strategic Timing

The timing of this acquisition aligns with strengthening prices for platinum group elements, driven by rising global demand and constrained supply. These market conditions enhance the economic prospects of the Munni Munni Project, which had previously seen development delays due to softer PGE markets rather than geological limitations.

GreenTech’s Non-Executive Chairman, Simon Kidston, emphasised the transformative nature of the acquisition, highlighting the consolidation of a dominant district-scale footprint and the strategic importance of the project within the company’s portfolio. The company’s commitment to sole-funding the joint venture through to a bankable feasibility study further underscores its confidence in the asset’s potential.

Looking Ahead – Exploration and Development Pathways

With drilling well underway and a second rig mobilised to accelerate the program, GreenTech is poised to deliver updated resource estimates and metallurgical insights in the near term. The project’s location on granted mining leases and proximity to existing processing infrastructure in the Pilbara region add to its appeal, although no current processing agreements are in place.

As GreenTech advances its exploration and evaluation activities, the market will be watching closely for results that could validate the historical resource and reveal new zones of mineralisation. The company’s ability to navigate the technical and commercial challenges ahead will be pivotal in realising the full value of this high-grade PGE-Cu-Ni asset.
