March quarter delivers strong production and cash-flow

It was another strong quarter at the Abra mine, with the March quarter delivering record production and cash-flow through optimisation and value creation initiatives.

As well as strong silver and lead production, progress was made across multiple fronts.

Endurance strengthened its balance sheet, expanded its exploration activities and improved energy efficiency in a difficult global environment.

Highlights include:

• Record EBITDA of $37.6m, free cashflow of $19.8m and net cashflow of $19.7m.
• Compared to 31 December 2025, EBITDA, free cashflow and net cashflows increased by 93%, 125% and 131%, respectively.
• Record C1 cost of $0.17/lb and AISC of $0.37/lb.
• Ore mined of 366,151 tonnes at 27.4g/t Ag and 7.4% Pb.
• Ore tonnes processed of 335,423 tonnes, head grades of 28.5g/t Ag and 7.6% Pb.
• Record lead grades mined and processed.
• Record concentrate produced of 38,755 tonnes and concentrate grades of 188.0g/t Ag and 60.3% Pb.
• Following the implementation of the January 2026 MRE, silver and lead grades have reconciled within 2% of the F3 mine reconciliation model.
• 12-month moving average reconciliation of Declared Ore Mined (DOM) against the 2026 Mineral Resource Estimate of 106% ore tonnes, 102% lead grade and 102% silver grade.
• An expanded $2.4m Abra Underground Exploration programme was approved.
• Approved to drill priority regional targets within trucking distance to the plant commencing in Q4. 

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

“Abra has delivered another record quarter, underpinned by strong operational performance and disciplined execution. Importantly, this performance is translating into a growing cash position, strengthening the balance sheet and providing increased flexibility as we continue to reduce debt and grow earnings.

“In a volatile global environment, we have taken meaningful steps to enhance the operation’s energy security. The integration of solar generation and LNG infrastructure has materially reduced our reliance on diesel, which now accounts for less than 10% of total energy consumption. This not only lowers operating costs but positions Abra as a resilient and sustainable project.

“Alongside consistent production, we are increasingly encouraged by the potential of our large exploration tenure. Additional drilling has been approved at Manganese Range, Copper Chert and Coolina as we accelerate our strategy to identify alternate near-mine feed sources that have the potential to transform Abra into a multi-decade, diversified revenue stream operation.

“These outstanding results are a credit to the entire Endurance team. Our people are the foundation of our success and their commitment and teamwork has us well positioned in building a silver focused, mid tier, multi asset metals miner renowned for endurance.”
