Munni Munni Phase 1 Drilling Results
Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to advise that its joint venture partner at the Munni Munni Platinum-Palladium-Copper-Nickel Project ("Munni Munni" or the "Project"), GreenTech Metals Limited (ASX: GRE) ("GreenTech"), has announced results from the Phase 1 drilling programme at Munni Munni in the West Pilbara region of Western Australia.
Alien holds a 30% interest, free carried to the completion of a bankable feasibility study at Munni Munni, together with 47 million GreenTech shares, representing a 17.1% interest in the issued share capital of GreenTech, providing Alien with exposure to key critical metals and precious metals including copper, nickel, platinum, and palladium.
Highlights from the GreenTech announcement:
· Results from the Phase 1 Munni Munni drilling programme demonstrate new, thicker PGE-Cu-Ni zones and provide expected validation of historic drilling through twin holes and core resampling.
· New infill drilling results have reported some of the highest individual metal PGE3 (Pt, Pd) + Au grades seen at the Ferguson Reef (8.8g/t PGE3, 0.65% Cu, 0.35% Ni), supporting GreenTech's focus on shallow zones of high-grade PGE-Cu-Ni mineralisation.
· New Reverse Circulation (RC) and Diamond (DD) selected drilling results:
o 12m @ 3.13 g/t PGE3, 0.30% Cu, 0.17% Ni from 90m; incl. 2m @ 8.37 g/t PGE3, 0.63% Cu, 0.34% Ni from 98m (26GTRC010)
o 11m @ 1.15 g/t PGE3, 0.15% Cu, 0.11% Ni from 116m; incl. 2m @ 2.96 g/t PGE3, 0.34% Cu, 0.18% Ni from 117m (26GTRC011)
o 15m @ 1.70 g/t PGE3 from 24m; and 3m @ 0.34% Cu, 0.16% Ni from 22m (26GTRC007)
o 6m @ 2.26 g/t PGE3 from 173m; and 2m @ 1.75 g/t PGE3 from 183m (26GTRC006)
· Twin Hole Drilling - direct validation of historic dataset
o 11m @ 1.88 g/t PGE3, 0.14% Cu, 0.09% Ni from 526m; incl. 1m @ 4.43 g/t PGE3, 0.46% Cu, 0.21% Ni from 535m (26GTDD004)
o 4m @ 2.29 g/t PGE3, 0.29% Cu, 0.16% Ni from 244m (26GTDD002)
o 6m @ 1.57 g/t PGE3 from 324m; and 7m @ 0.40% Cu, 0.15% Ni from 322m (26GTRCD003)
o 12m @ 1.08 g/t PGE3 from 186m; incl. 2m @ 2.27 g/t PGE3 from 186m (26GTDD001)
· Historic Core Resampling - selected highlights from 16 historic holes
o 2m @ 5.90 g/t PGE3, 0.19% Cu, 0.14% Ni from 107m; and 2.75m @ 0.66 g/t PGE3 from 101.5m (MMD117)
o 4.5m @ 2.67 g/t PGE3 from 50.75m; and 4.75m @ 0.23% Cu, 0.12% Ni from 47m (MMD115)
o 2m @ 2.64 g/t PGE3, 0.25% Cu, 0.11% Ni from 137.5m; and 3.5m @ 1.26 g/t PGE3 from 142m (MMD045)
o 11.25m @ 1.49 g/t PGE3 from 754.75m; incl. 6.25m @ 2.22 g/t PGE3 from 755.75m (MMD084)
o 22m @ 0.89 g/t PGE3 from 770m; incl. 5m @ 1.86 g/t PGE3 from 772.5m (MMD099)
· Mineralisation outcrops on surface across the Ferguson Reef with broader PGE-Cu-Ni grade envelopes identified in new RC drilling supporting shift to considering bulk mining potential at Munni Munni.
· All assay data will support the re-estimation of the Munni Munni Resource to JORC (2012), using PGE4 (Pt, Pd, Rh) + Au grade and inclusion of payable copper and nickel using an NSR cut-off.

Notes to Editors
Alien Metals Ltd is a mining exploration and development company listed on the AIM market of the London Stock Exchange (AIM: UFO). The Company follows a balanced strategy of advancing and strengthening its asset portfolio through targeted technical work and project development, while evaluating partnerships, joint ventures, and selective monetisation opportunities that are value-enhancing for shareholders. At the same time, Alien will continue to consider opportunities to expand our asset base through carefully selected acquisition opportunities which meet the Board's prudent 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 has divested a 70% interest in the Munni Munni tenements to GreenTech and Alien will retain a 30% interest, free carried to the completion of a bankable feasibility study at Munni Munni. Alien (via wholly owned subsidiary A.C.N. 643 478 371 Pty Ltd) 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.
