Alien Metals Limited (LON:UFO) has noted that GreenTech Metals Limited has announced mobilisation plans for its upcoming drilling programme at the Munni Munni PGE-Cu-Ni Project and the Whundo Cu-Zn-Au Project, located in the West Pilbara of Western Australia.
Key Highlights:
| · | Drill rig contracted with mobilisation to site planned for late July 2026, with a second rig expected to commence operations following the completion of additional heritage clearances. |
| · | Government co-funded Fixed-Loop Electromagnetic (“FLEM”) geophysical survey scheduled to commence in early July across selected sections of the largely untested basal contact of the Munni Munni intrusion. |
| · | Eight-day heritage survey scheduled to commence on 10 August 2026 to clear additional drill locations and access routes across the Munni Munni mineralised footprint and priority basal target areas. |
| · | Initial drilling programme to prioritise existing cleared drill pads at Munni Munni and high-priority Cu-Au extension targets at Whundo. |
| · | Board-approved exploration programme comprising approximately 4,750 metres of Reverse Circulation (“RC”) drilling and 3,560 metres of diamond drilling (“DD”), including larger diameter holes for metallurgical composite sampling. |
| · | Ongoing resource re-estimation and metallurgical workstreams continue to advance, with particular focus on copper-dominant mineralisation and production of a Cu-PGE concentrate. |

Mobilisation and Drilling Programme
A drill rig has been contracted for mobilisation to site in late July 2026, with a second rig expected to commence operations once additional drilling areas receive heritage clearance.
The approved exploration programme comprises approximately 4,750 metres of RC drilling and 3,560 metres of DD. The programme includes wider-diameter diamond holes designed to collect metallurgical composite samples.
Initial drilling at Munni Munni will be undertaken from existing cleared drill pads, while drilling at Whundo will focus on testing extensions to known high-grade copper-gold mineralisation and collecting material for metallurgical testwork to support future resource updates.
Heritage Survey
An eight-day heritage survey is scheduled to commence on 10 August 2026.
The programme is designed to clear additional drill locations and access routes across the Munni Munni mineralised footprint, together with other priority basal contact target areas identified through ongoing geophysical work.
This phased mobilisation strategy allows drilling to commence immediately from existing approved locations while ensuring efficient utilisation of drilling equipment as further areas become available.
Fixed-Loop Electromagnetic Survey
A Government co-funded Fixed-Loop Electromagnetic (FLEM) survey is scheduled to commence in early July.
The survey will cover approximately 8.2km² across 56.4 line kilometres using four large transmitter loops with 75-metre station spacing.
The programme has been specifically designed to identify conductive bedrock targets associated with potential copper sulphide mineralisation along the largely untested basal contact of the Munni Munni intrusion.
The total survey cost is estimated at approximately A$200,000, with A$100,000 provided through the Western Australian Government’s Co-funded Geophysics Programme.
Survey results are expected to assist in refining drill targeting ahead of the planned drilling programme.
Resource and Metallurgical Workstreams
Work continues on the planned Munni Munni Mineral Resource re-estimation, with geological modelling and metallurgical testwork progressing.
Current metallurgical studies remain focused on demonstrating the suitability of conventional flotation techniques while expanding the programme to better characterise the copper-PGE sulphide assemblage and define processing parameters required to produce a Cu-PGE concentrate.
The expanded emphasis on copper reflects current market conditions and ongoing discussions with potential offtake partners. Results from the metallurgical programme are anticipated during August and are expected to support net smelter return parameters for incorporation into the updated Mineral Resource estimate and an initial Scoping Study.
