Polymetals on Track at Endeavor Mine with First Ore Hoisted and Processing Imminent

21 May 2025 | Alstonville, NSW – Polymetals Resources (ASX:POL) has confirmed that redevelopment of its Endeavor Silver-Zinc Mine is progressing on schedule and within budget, with commissioning well underway and first cash flow expected in June.

Following the completion of major site works and infrastructure upgrades, the site has entered full commissioning. Crushed ore is being hoisted and stockpiled, with wet commissioning of the plant in progress and ore processing scheduled to begin next week.

Key highlights:

• First ore crushed and hoisted to surface

• Over 40,000 tonnes of ore stockpiled underground

• Site targeting 65,000t/month processing rate in H2 2025

• First mining of high-grade silver ore set for July 2025

Executive Chairman Dave Sproule said:

“We’re proud of the rapid, in-house development at Endeavor — a rarely achieved feat at this scale. First processing is imminent, and our shareholders are seeing real value for money.”

In parallel, diamond drilling continues at the Carpark prospect, targeting extensions of the Main Lode. Results will be released once the current program is completed.

Polymetals is aiming to become a long-term base and precious metal producer from the Cobar Basin, with the Endeavor restart marking a critical milestone in that journey.
