Elizabeth Hill Silver
Overview
West Coast Silver holds a 70% interest (via Crest Silver) in the Elizabeth Hill Silver Project (Mining Lease M47/342), located ~45 km south of Karratha in the West Pilbara, with the remaining 30% held by subsidiaries of Alien Metals. The Project includes the historic Elizabeth Hill mine — Australia’s highest-grade silver producer in 1999–2000 — and now an inaugural JORC 2012 Mineral Resource of 2.8 Moz Ag at 617 g/t, set within a ~180 km² contiguous land package.

Elizabeth Hill Silver Project – A High-Grade Opportunity
The Elizabeth Hill Silver Project stands as one of Australia’s highest-grade silver assets, underpinned by remarkable historical production and significant upside potential for future development.
Once a prolific producer, the project is now poised for a resurgence, supported by modern exploration techniques and rising silver prices.
Proven High-Grade Production
Elizabeth Hill has a proven history of exceptional silver production. Between 1999 and 2000, the mine produced 1.2 million ounces of silver from just 16,830 tonnes of ore at a recovered head grade of 2,194 g/t (70.5 oz/t Ag).
This was accomplished using low-cost gravity separation methods to recover native silver, highlighting the project’s processing efficiency and high-margin potential.
Strategic Location and Development Advantages
Elizabeth Hill is located within a Tier-1 mining jurisdiction and sits on an existing mining lease, streamlining the permitting and development process. The project also offers a potential processing pathway via the nearby Radio Hill facility, which could significantly reduce capital expenditure requirements for future production.
Although mining operations ceased in 2000 due to historically low silver prices (~US$5/oz at the time), the April 2026 MRE pit optimisation — completed at a long-run silver price assumption of US$60/oz (A$85.71/oz) — confirmed reasonable prospects for eventual economic extraction within a compact open pit on the granted Mining Lease, with potential processing pathway via the nearby Radio Hill facility.
Inaugural Mineral Resource Estimate — April 2026
The Elizabeth Hill Silver Project hosts an inaugural JORC 2012 Mineral Resource Estimate of 141,000 tonnes at 617 g/t Ag for 2.8 Moz of contained silver, comprising 369,000 oz Indicated and 2.42 Moz Inferred, reported at a 20 g/t Ag cut-off and constrained within an optimised open pit generated at A$85.71/oz Ag (US$60/oz at 0.70 AUD/USD). The Competent Person for the Mineral Resource is Mr Phil Jankowski FAusIMM of ERM Australia Consultants Pty Ltd. Refer to the ASX announcement dated 22 April 2026 for full details.
84 kt @ 137 g/t Ag for 369 koz
57 kt @ 1,331 g/t Ag for 2,426 koz
141 kt @ 617 g/t Ag for 2,795 koz.
Demonstrated Resource Growth and Exploration Potential
Recent RC drilling results in June 2026 has confirmed silver mineralisation extending up to 70m beyond the April 2026 maiden MRE of 2.8Moz Ag at 617g/t Ag, including broad intersections of 60m @ 25g/t Ag from surface. The majority of new mineralisation lies outside the current resource boundary, demonstrating a clear pathway for future resource growth. Mineralisation remains open along strike and at depth, with 86% of current silver ounces classified as Inferred, providing substantial upside through ongoing drilling and resource conversion. Further assay results are pending from 15 RC drill holes, while diamond drilling is underway to test extensions below recent mineralised intersections and support future resource growth.
Outstanding Geology and Silver Mineralisation
The project is underpinned by outstanding geology and high-grade silver mineralisation, supported by recent drill results including:
These results reaffirm the high-grade nature of the mineral system and the project’s potential for further resource growth.
