Endurance delivers 2026 Ore Reserve Estimate

Endurance Mining Pty Limited is pleased to report a 2026 Ore Reserve Estimate for its Abra Operation as at 30 June 2026.

The update highlights include:

• 2026 Ore Reserve Estimate of:
  • 5.7Mt grading 6.2% lead and 22.7g/t silver for 352.8Kt of contained Pb and 4.1Moz of contained Ag at a tonnes-weighted-average Net Smelter Return (NSR) of approximately A$160/t ore.
• Ore Reserve Statement independently developed and reviewed by MOS Mining Consultancy.
• Ore Reserve is a subset of previously disclosed 2026 Mineral Resource Estimate (‘MRE’) independently reviewed and endorsed by Entech Pty Ltd.
• The Resource and Reserve do not include any drilling results received throughout CY2026 and is based on the last resource model as of December 2025.
• Recent regional and underground exploration results remain highly encouraging, indicating potential to further grow the Abra resource and reserves base.

Said CEO Matthew Hine:

“The 2026 Ore Reserve represents a critical milestone for Endurance following our updated Mineral Resource Estimate earlier this year. It’s Abra’s first reserve release since 2018 and has been independently delivered by MOS Mining Consultancy. The result highlights the quality of the Abra deposit and the geological and technical understanding our geology and engineering teams have developed over the past eighteen months. 

“Our large resource and reserve base underpin a strong, long-term outlook for the operation and we believe provides a platform for further production growth and mine life extensions.

“We look forward to releasing results of our CY2026 exploration programme which has targeted satellite projects proximal to Abra’s infrastructure along with underground extensions to the current orebody. With silver and lead critical inputs to renewable power, vehicles and data centres, the Company is well advanced in its emergence as a multi asset metals miner, renowned for endurance.”
