Strong June 2026 quarter across safety, production and financial results

The June quarter marked another quarter of Endurance delivering record safety, production and financial results.

This marks the fifth consecutive quarter of Endurance delivering planned tonnes and grade, further demonstrating our operating credentials, while investment in enabling infrastructure and exploration has positioned us to push the bar even higher in FY27.

Mining and Exploration Strategy

  • AUD1300 – 8.0m @ 34.3 g/t Ag and 8.0% Pb from 385.2m (Western Extension of Apron zone).
• To support the Abra Underground Exploration Programme a third diamond drill rig arrived at the mine site during the quarter.
• Outstanding results from 2,694m Reverse Circulation (RC) regional exploration programme at Manganese Range and Copper Chert

Matthew Hine, Endurance Mining’s CEO and Managing Director said:

“The June 2026 quarter represented another stride forward in Abra’s transformation and Endurance

Mining’s vision of building a silver focused, multi asset metals miner, renowned for endurance.

“In just twelve months we have delivered record safety, production and financial results while

simultaneously derisking the operation and investing heavily in its future.

“The Ore Reserve Estimate was the first released since 2018 and demonstrates a strong operating

foundation on which to grow. Regional exploration results at Manganese Range and Copper Chert

continue to surprise on the upside and are symbolic of the range of organic growth opportunities that

could rapidly be brought into production. Meanwhile the first extensional holes testing the extents of

the Abra deposit consistently show economic widths at elevated silver and lead grades.

“We continued to firm up the balance sheet by paying down debt and are mitigating global uncertainty

through foreign exchange hedging and the implementation of a US$10m working capital facility which

remains undrawn. Our fifth consecutive quarter of delivering planned tonnes and grade further

demonstrates the teams operating credentials, while investment in enabling infrastructure has

positioned us to push the bar even higher in FY27.

“12 months ago, Endurance emerged from a Deed of Company Arrangement with just $1m cash in the

bank and a plan on a page. What we’ve achieved in a short period of time is incredible. It’s a testament

to the quality of our people, their commitment to living the values, and buy in to the Company’s strategy.

I’m proud of what our teams achieved and look forward to taking that momentum into FY27”.
