Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to report that its joint venture partner, West Coast Silver Limited (ASX: WCE) (formerly Errawarra Resources Limited) (“West Coast Silver”), has announced that its inaugural diamond drill program (12 holes for 1,183m) at the high-grade Elizabeth Hill Silver Project (“Elizabeth Hill” or the “Project”) in the Pilbara region of Western Australia has been completed. It has delivered exceptional results, with shallow, high-grade silver assays returned from the first two drill holes. The Project, in which Alien retains a 30% free-carried interest through to a decision to mine, is operated by West Coast Silver.

Highlights:

  • Assays from drill hole 25WCDD001, the first drill hole completed from the 2025 program has returned a significant high-grade silver (Ag) zone:
    • 21 metres at 1,047g/t Ag from 10 metres including:
      • 8 metres at 2,632 g/t Ag from 22 metres including:
        • 1 metre at 15,071 g/t Ag from 27 metres.
  • Impressive near surface results from drill hole 25WCDD002 include:
    • 15 metres at 723g/t Ag from 1 metre including:
      • 3 metres at 2,639g/t Ag from 1 metre.
  • Gold (Au) reported in laboratory assays with peak assay from drill hole 25WCDD002 returning:
    • 1 metre at 2.03g/t Au from 4 metres.
  • To date, only assay results for holes 25WCDD001 & 25WCDD002, have been received from the laboratory. However, the new intersections of near-surface high grade silver provide impetus for further evaluation and quantification of potential economic shallow silver mineralisation.
  • Review of historical drilling data provides additional indication of economic near surface mineralisation.
  • The additional eight drill holes have been dispatched to the laboratory for assay with results expected progressively over a 6–8 week period.
  • Whilst the drilling component of the programme has been completed, logging of holes 11 & 12 continues, and samples will be dispatched to the laboratory once ready.
