Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to report thatits joint venture partner, West Coast Silver Limited (ASX: WCE) (formerly Errawarra Resources Limited), has announced further outstanding assay results from the maiden diamond drill programme at the Elizabeth Hill Silver Project (“Elizabeth Hill” or the “Project”) in the Pilbara region of Western Australia. The Project, in which Alien retains a 30% free-carried interest through to a decision to mine, is operated by WCE.

Highlights:

  • Assays from drill hole 25WCDD011 have identified several significant high-grade silver zones
    including:
    o 17m @ 858g/t Ag from 5m, including 2m @ 6,349g/t Ag from 7m;
    o 10m @ 850g/t Ag from 47m, including 3m @ 2,593g/t Ag from 50m; and
    o 13m @ 1,615g/t Ag from 62m, including 2m @ 10,049g/t Ag from 63m.
  • Native silver observed in drill core from 25WCDD011.
  • Significant high-grade gold intercept: 1m @ 11.1 g/t Au from 51m in 25WCDD011.
  • Drill hole 25WCDD012 also returned high-grade silver intercepts, including:
    o 6m @ 317g/t Ag from 10m, including 1m @ 1,455g/t Ag from 13m; and
    o 14m @ 162g/t Ag from 18m.
  • Results continue to confirm the presence of near-surface, high-grade silver mineralisation at
    Elizabeth Hill.
  • Assay results for a further six holes from the inaugural 12-hole (1,183m) diamond programme
    remain outstanding.

25WCDD011: 52.01-52.2m (SAMPLE 25WC04-015) – Silver-grey native silver and silver sulphide minerals 1mm to 2mm in size comprise about 1% of the fine-grained quartz and coarse grained calcite vein. Quartz comprises about 20% and calcite about 80% of the vein.
