Artemis and West Coast Silver Sign Joint Memorandum of Understanding on Radio Hill

Highlights

• West Coast Silver (ASX: WCE) and Artemis Resources (ASX: ARV) have jointly executed a non-binding Memorandum of Understanding to collaboratively assess processing options for the Elizabeth Hill Silver Mine.
• The evaluation will focus on the suitability of the Radio Hill Processing Plant to potentially treat material from West Coast Silver's Elizabeth Hill Silver Mine.
• Both parties will exchange relevant technical, metallurgical, logistical, and engineering information. Site visits and joint technical assessments will be undertaken where required.
• Any future toll treatment or commercial arrangement remains subject to a separate definitive agreement following a positive technical and commercial assessment.

West Coast Silver Limited (ASX: WCE) (West Coast or the Company) is pleased to jointly announce that it has entered into a non-binding Memorandum of Understanding (MOU) with Artemis Resources (ASX: ARV) (Artemis) to evaluate the potential for Artemis' Radio Hill Processing Plant, located near Karratha, to process material sourced from West Coast's Elizabeth Hill Silver Mine in the Pilbara.

Under the terms of the MOU, West Coast and Artemis will work together in good faith to determine whether the Radio Hill Processing Plant could feasibly and economically process ore or material originating from the Elizabeth Hill Silver Mine. This cooperation includes the exchange of technical data, metallurgical samples, plant configuration details, and logistical information relating to transport and handling.

Commenting on the aircore program, Executive Director Bruce Garlick commented:

"Elizabeth Hill is one of Australia's historically highest-grade silver deposits. The opportunity to assess Radio Hill as a potential processing solution aligns with our strategy to fast-track development while maintaining capital discipline."

Artemis Resources Executive Director, Joszef Patarica commented:

"Radio Hill has historically demonstrated versatility across multiple ore types. This cooperation allows us to assess future processing opportunities while supporting potential development of a high-grade silver project in our region."

Confidentiality & Costs

The MOU is non-binding and does not create any commercial obligations, partnership, or joint venture between the parties. Any formal processing agreement, including toll treatment arrangements, will only proceed subject to the completion of a favourable technical and commercial assessment and subsequent negotiation of a definitive binding agreement. There are no financial obligations on either party until the parties agree to proceed to a binding agreement.

Both companies have agreed to maintain the confidentiality of exchanged information, subject to obligations under the Corporations Act 2001 (Cth) and the ASX Listing Rules. Each party will bear its own costs associated with the preparation and implementation of the MOU.

Next Steps

Technical teams from both companies will now commence data sharing, review of plant capabilities, and assessment planning. West Coast and Artemis will provide further updates as material progress is made.

Key Terms of the Agreement

About Radio Hill

The Radio Hill Processing Plant is a fully permitted 425,000 tonnes per annum (tpa) nickel-copper concentrator located 35 km south of Karratha in Western Australia's Pilbara region. Artemis purchased the plant in 2016 and surrounding assets from Fox Resources. The plant includes flotation circuits, tailings storage facility, administration and maintenance buildings, fully developed underground mine and Gekko gravity plant. The plant remains on care and maintenance but can be rapidly recommissioned.
