On 03 July 2026, Alien Metals Limited noted that GreenTech Metals Limited announced mobilisation plans for its drilling programme and geophysical survey at the Munni Munni and Whundo projects. GreenTech has contracted a drill rig for mobilisation in late July 2026 for an approved programme of approximately 4,750 metres of RC drilling and 3,560 metres of diamond drilling. An eight-day heritage survey is scheduled for 10 August 2026, and a Western Australian Government co-funded Fixed-Loop Electromagnetic survey, estimated to cost A$200,000 (with A$100,000 government contribution), is set to commence in early July.

Munni Munni and Whundo Drill Update
Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to note that GreenTech Metals Limited (ASX: GRE) ("GreenTech") has announced mobilisation plans for its upcoming drilling programme at the Munni Munni PGE-Cu-Ni Project ("Munni Munni") and the Whundo Cu-Zn-Au Project ("Whundo"), 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.

Notes to Editors
Alien Metals Ltd is a mining exploration and development company quoted on the AIM market of the London Stock Exchange (AIM: UFO). The Company follows a balanced strategy focused on advancing and strengthening its asset portfolio through targeted technical work and project development, while evaluating partnerships, joint ventures, and selective monetisation opportunities to enhance shareholder value. At the same time, Alien will continue to consider opportunities to expand its asset base through carefully selected acquisition opportunities consistent with the Board's disciplined investment criteria.
Alien's principal focus is the advancement and development of its 90%-owned Hancock Iron Ore Project in the central Pilbara region of Western Australia. The Hancock tenements contain a JORC-compliant resource of 8.4Mt at 60% Fe and offer significant exploration upside, which is targeted to deliver a mining operation of 2Mtpa for 10 years. The Project benefits from direct access to the Great Northern Highway, providing a route to export facilities at Port Hedland, one of the world's largest iron ore export hubs. Alien also holds exploration interests in the Brockman and Vivash iron ore projects in the West Pilbara.
Alien additionally retains exposure to two advanced precious and base metal assets in the Pilbara. At Munni Munni, one of Australia's largest PGM systems hosting a historic resource of 2.2Moz PGM (palladium, platinum, and rhodium) and gold, the Company has completed its partial asset sale and joint venture transaction with GreenTech Metals Ltd under which Alien retains a 30% interest, free carried to completion of a bankable feasibility study at Munni Munni, and additionally holds 37.9 million shares in GreenTech Metals Ltd. Alien (via a wholly owned subsidiary) also retains a 30% interest in the Elizabeth Hill Silver Project through a joint venture with Crest, which encompasses the Elizabeth Hill Mining Lease M47/342, which has produced some of Australia's highest-grade silver ore during the late 1990s. Alien retains a 30% interest in the Elizabeth Hill Silver Project and additionally holds 30.5 million shares in West Coast Silver Limited, providing both direct project exposure and equity participation in ongoing development.
