Alien Metals Limited (LON:UFO), a minerals exploration and development company, has noted that its joint venture partner, West Coast Silver Limited (ASX: WCE), has today released an updated JORC (2012) Mineral Resource Estimate for the Elizabeth Hill Silver Project in the West Pilbara, Western Australia. Alien holds a 30% free-carried interest in Elizabeth Hill and approximately 7.0% of West Coast Silver.
Highlights:
| • | Updated MRE: 234,700 tonnes at 446g/t Ag for approximately 3.36 million ounces of contained silver (100% project basis), reported at a 20g/t Ag cut-off |
| • | Resource growth: a 20.3% increase in contained silver on the inaugural April 2026 MRE of 141,000 tonnes at 617g/t Ag for approximately 2.8 million ounces |
| • | Higher confidence: 77% of contained silver now in the Indicated category, up from c.13% in April 2026 |
| • | Next steps: Results from the current diamond drilling programme will inform a further MRE update targeted for March 2027, ahead of the maiden Elizabeth Hill Scoping Study. |
| • | Alien exposure: Alien retains a 30% project interest, free-carried until a decision to mine, and holds 30.5 million West Coast Silver shares (approximately 7.0% of its issued share capital) |
Vince Fayad, Executive Director of Alien Metals, commented:
“West Coast Silver’s updated Mineral Resource is a significant step forward for Elizabeth Hill, lifting contained silver to approximately 3.36 million ounces at an exceptional grade and materially increasing the proportion in the higher-confidence Indicated category. It reinforces Elizabeth Hill’s position as one of Australia’s highest-grade silver projects, at a time of strong silver prices. We look forward to the follow-up drilling and Scoping Study outcomes as West Coast Silver advances Elizabeth Hill towards a development decision.”
