Munni Munni Project
In December 2025, GreenTech Metals announced it had entered into binding agreements with Alien Metals Limited (AIM: UFO) to acquire up to 80% of the historical Munni Munni PGE Project (“Project” or “Munni Munni”).
The Project includes four mining leases and two exploration tenements. In addition, GRE purchased 100% of an additional two exploration tenements at Munni Munni South. The collective tenement package consisting of ML’s and EL’s totals 346km2 in the Tier 1 mining jurisdiction of the Pilbara, Western Australia, adjacent to the Company’s Whundo Copper-Gold deposit.
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; WCE 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.

Cautionary Statement
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).
