GreenTech Metals Clears Heritage Hurdle, Opening Way for Munni Munni Copper Drilling
Key Takeaways
- GreenTech Metals has completed its heritage survey with the Ngarluma Traditional Owners, clearing drill locations and access routes at Munni Munni.
- Drilling will target extensions to shallow copper mineralisation at Ferguson Reef and high-priority copper targets along the intrusion's basal contact.
- No drilling start date, metres, hole counts, grades or budget have been disclosed, so the next catalyst is drill results still to come.
- Further heritage surveys are being planned at Munni Munni to support future exploration.
- Munni Munni sits just 10km from the Whundo project within a landholding of more than 500km² in the West Pilbara.
Heritage survey completed at Munni Munni, clearing path for copper drilling
GreenTech Metals (ASX: GRE) has completed Heritage Survey work with the Ngarluma Traditional Owners over priority exploration areas at the Munni Munni PGE-Cu-Ni Project in the West Pilbara, Western Australia. The result opens the way for Munni Munni copper drilling.
The survey cleared proposed drill locations and access routes. Drilling is set to commence following site preparation, though the announcement does not give a start date.
For investors, a pre-drilling approval step is now behind the company. The next catalyst to watch is drill results, which the announcement does not yet quantify.
James Rattenbury, Chief Executive Officer
“Completion of this heritage survey work in collaboration with the Ngarluma Traditional Owners is an important milestone as we progress our next phase of drilling at Munni Munni…”

What the drill program will target
The program has two focus areas, both aimed at copper. The announcement contains no drill metres, hole counts, grades or budget.
Ferguson Reef shallow copper
Drilling will focus on extensions to shallow copper mineralisation at the Ferguson Reef.
“Extensions” means testing whether known copper mineralisation continues beyond where it has already been identified.
Basal contact targets
The second focus is high-priority copper targets along the basal contact of the Munni Munni intrusion. The basal contact is the lower boundary of the intrusion, and these targets were identified through ongoing geophysical work at the Project.
The survey cleared:
- Drill locations targeting the Munni Munni mineralised footprint
- High-priority basal contact targets identified through geophysical work
- Access routes for the proposed drilling
| Target | Why it matters |
|---|---|
| Ferguson Reef | Drilling will focus on extensions to shallow copper mineralisation |
| Basal contact | High-priority copper targets identified through ongoing geophysical work |

Why heritage surveys matter for explorers
A heritage survey is conducted with Traditional Owners before ground disturbance. It aims to identify and protect cultural sites, and it is a standard step before drilling in Western Australia.
For you as an investor, cleared areas reduce the risk of delays to drilling. GreenTech describes its engagement with the Ngarluma Traditional Owners as constructive.
Planning is also underway for further heritage survey work at Munni Munni to support future exploration activities.

Next steps and project context
The sequence is site preparation, then drilling, with further heritage surveys planned. Timing for drilling has not been disclosed.
GreenTech describes a dominant >500km² landholding in the West Pilbara. Its Munni Munni (PGE-Cu-Ni) and Whundo (Cu-Zn-Au) projects sit only 10km apart.
The company describes Munni Munni as “One of Australia’s most significant Platinum Group Element (PGE) layered mafic intrusions.” PGEs are a group of rare metals that include platinum and palladium.
GreenTech states its strategy is to discover, define and develop a multi-commodity district to supply the growing demands of the green energy and critical minerals markets. Drill results will be the test of how far that strategy progresses.
For readers wanting to see how GreenTech is pursuing scale beyond Munni Munni, our deep-dive into the Whundo exploration target explains how the company sized the copper potential at its neighbouring project and what that means for the district strategy.
