GreenTech Metals Advances Munni Munni Project Towards JORC Resource

GreenTech Metals Accelerates Path to JORC 2012 Resource at World-Class Munni Munni PGE Project

GreenTech Metals (ASX: GRE) has successfully completed its Phase 1 drilling programme at the GreenTech Metals Munni Munni project ahead of schedule, marking a significant step toward unlocking one of Australia's most substantial platinum group element deposits. The programme's early completion, driven by the exceptional preservation of historical drill core, positions the company to fast-track its path to a modern JORC 2012 resource estimate.

The drilling campaign achieved remarkable efficiency by combining 12 new drill holes (2,682 metres) with strategic resampling of 16 historical drill holes, creating a comprehensive dataset of 2,143 samples now undergoing analysis. This innovative approach delivered substantial cost savings whilst accelerating the timeline toward resource validation for a project hosting a historical resource of 24 Mt @ 2.9 g/t 4E for 2.2 million ounces.

"We are very pleased that our Phase 1 drill programme at Munni Munni was completed ahead of schedule due to the availability and suitability of the stored historical drill core at Munni Munni. This has accelerated our programme, reduced costs, and pushes us closer to a key objective of unlocking the full potential of this world-class Platinum-Palladium-Copper-Nickel project," said CEO James Rattenbury.

Strategic Drill Programme Delivers Operational Excellence

The Phase 1 programme demonstrates GreenTech's tactical approach to resource validation. Originally planning 20 holes for 6,000 metres, the company adapted its strategy upon discovering the remarkable preservation of historical core stored on-site. This flexibility enabled the company to achieve its validation objectives through a modified approach.

Furthermore, the new drilling component included 6 diamond/RC holes for fresh geological data and 6 infill RC holes targeting resource continuity in key areas. The 2,682 metres of total new drilling completed provided essential validation data for the project.

Additionally, the historical core integration involved 16 historical drill holes resampled from preserved core. The excellent core preservation enabled reliable geochemical analysis whilst delivering significant cost savings compared to re-drilling equivalent positions.

The combined approach created a robust database for resource validation whilst maintaining the geological integrity required for JORC 2012 compliance. All samples have been dispatched to ALS Global laboratories in Perth, with initial results expected in April and full results anticipated within 4-6 weeks.

Understanding Platinum Group Elements: Critical Metals for Energy Transition

Platinum Group Elements (PGEs) represent some of the world's rarest and most valuable metals, comprising platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals possess unique catalytic properties that make them irreplaceable in numerous industrial applications.

Key Industrial Applications of PGEs

The industrial applications of PGEs span multiple critical sectors:

• Automotive catalysts: Essential for reducing vehicle emissions in petrol and diesel engines
• Green hydrogen production: Critical components in electrolysis equipment and fuel cell technologies
• Chemical processing: Irreplaceable catalysts in petroleum refining and chemical manufacturing
• Electronics: Essential components in computer hard drives and electronic devices

The global transition to cleaner energy technologies has created unprecedented demand for PGEs, particularly in hydrogen fuel cells and emission control systems. With over 80% of global platinum supply concentrated in South Africa, projects like the GreenTech Metals Munni Munni project represent rare opportunities to access these critical metals in a stable mining jurisdiction.

Why PGEs Matter to Investors

Several factors make PGEs attractive to investors:

• Supply concentration risk: Geological scarcity creates long-term supply constraints
• Demand diversification: Traditional automotive applications expanding into renewable energy sectors
• Strategic importance: Government recognition as critical minerals for energy security
• Price volatility: Supply disruptions can create significant price movements

Fast-Track to JORC 2012 Resource Validation

GreenTech has engaged Snowden Optiro, leading resource consultants, to undertake comprehensive quality assurance and quality control (QA/QC) validation of the historical resource data. This validation process forms the foundation for preparing a new Mineral Resource Estimate compliant with JORC Code 2012 standards, anticipated for completion in Q2 2026.

Current Validation Process

The validation process encompasses several critical components:

• Integration of new drilling data with historical database
• Modern analytical techniques applied to preserved core samples
• Statistical validation of historical assay results
• Geological modelling update incorporating current best practices

The transition to JORC 2012 compliance represents more than a technical update. It positions the GreenTech Metals Munni Munni project as a bankable asset ready for modern development consideration, particularly as PGE markets strengthen globally.

World-Class Asset in Premium Mining Jurisdiction

The Munni Munni Project benefits from several competitive advantages that distinguish it within the global PGE sector. The project represents one of Australia's most significant platinum group element intrusions, hosting a large, laterally continuous reef structure containing platinum, palladium, rhodium and gold.
