GreenTech Targets 2.2Moz PGE Resource Upgrade with 6,000m Drill Program
GreenTech Metals has initiated a Phase 1 drilling program at its Munni Munni project in Western Australia, aiming to upgrade a significant historical platinum group element resource to current compliance standards and explore expansion opportunities.
- Phase 1 drilling underway with up to 20 holes planned
- Historical resource of 24 Mt at 2.9 g/t 4E containing 2.2 million ounces
- Drilling to verify and upgrade resource to JORC (2012) compliance
- Consolidation with Whundo project to create a multi-commodity hub
- Rising PGE and copper prices underpin renewed project interest
Drilling Commences at Munni Munni
GreenTech Metals Limited (ASX – GRE) has officially kicked off a Phase 1 drilling campaign at its recently acquired Munni Munni Platinum-Palladium-Copper-Nickel (PGE-Cu-Ni) Project in Western Australia's West Pilbara region. This marks a pivotal step in the company’s strategy to validate and modernise a historically significant mineral resource that has remained largely dormant due to past market conditions.
The Munni Munni project boasts a historical, albeit non-compliant, mineral resource estimate of approximately 24 million tonnes grading 2.9 grams per tonne of combined platinum group elements plus gold (4E), equating to around 2.2 million ounces. This resource was defined through extensive drilling between 1985 and 2002 but has yet to be updated to current JORC (2012) standards, which is critical for advancing towards development.
Aiming for JORC Compliance and Resource Expansion
The current drilling program involves up to 20 reverse circulation and diamond drill holes totaling about 6,000 metres. Its primary objectives are to verify the historical resource through rigorous quality assurance and quality control (QA/QC) processes, upgrade the resource classification to JORC (2012) compliance, and explore extensions beyond the known mineralised envelope. Additionally, the program will collect samples for metallurgical testing, which is essential for assessing processing pathways.
GreenTech’s Executive Director, Thomas Reddicliffe, highlighted the excellent preservation of historical core samples on site, which will support the QA/QC verification. The company is also surveying historical drill collars to ensure precise spatial data for the resource model.
Strategic Consolidation and Market Tailwinds
Importantly, Munni Munni is adjacent to GreenTech’s Whundo Copper-Gold Project, and the company is working towards consolidating these assets into a contiguous land package exceeding 346 square kilometres. This consolidation is expected to create a district-scale exploration and development hub, potentially enhancing the economics of both projects.
Market dynamics provide a favourable backdrop for this initiative. Global demand for platinum group elements and copper is strengthening, driven by their critical roles in clean energy technologies and electrification. This price environment supports GreenTech’s ambition to unlock value from Munni Munni’s substantial PGE-Cu-Ni endowment.
Looking Ahead
The drilling program is scheduled to conclude by February 2026, with assay results expected within 4 to 6 weeks thereafter. These results will be closely watched by investors and analysts as they will inform the next phase of technical evaluation and potential development planning. GreenTech’s Chairman, Simon Kidston, emphasised the significance of this milestone in positioning the company for future growth and shareholder value creation.
Bottom Line?
As drilling progresses, GreenTech’s ability to convert historical data into a modern, compliant resource will be key to unlocking Munni Munni’s full potential amid rising metal prices.
Questions in the middle?
- Will the drilling confirm or exceed historical resource grades and tonnages?
- How will metallurgical test results influence processing strategies and project economics?
- What are the implications of the Whundo-Munni Munni consolidation for project scale and financing?
