BHM Achieves Record Ore Throughput as Pinnacles Mine Restarts

Record Throughput and Production Milestones

Broken Hill Mines (ASX:BHM) has delivered its strongest operational quarter since acquiring the Rasp asset, processing 119,320 tonnes of ore in the June 2026 quarter; a 3.2% increase quarter-on-quarter and the highest since June 2020. Silver production jumped 21.8% to 95,787 ounces, marking the best quarterly silver output since September 2022, while zinc production rose 7% to 3,330 tonnes. Lead production dipped slightly by 3.9%, settling at 2,376 tonnes.

June alone was a standout month, with 49,700 ounces of silver, 1,075 tonnes of lead, and 1,380 tonnes of zinc produced from 50,075 tonnes processed at a combined zinc and lead grade of 5.6% and 38 grams per tonne silver. This operational momentum underscores BHM's successful feed grade enhancement strategy, driven by increasing contributions from the high-grade Main Lode and the recently restarted Pinnacles Mine.

Pinnacles Mine Restart Drives Growth

The Pinnacles Mine restart marks a pivotal step in BHM’s plan to fully utilise its 750,000 tonnes per annum Rasp Processing Plant. After a hiatus since 2021, initial operations at Pinnacles are focused on the Edwards Open Pit, which offers access to up to 50,000 tonnes of high-grade ore in the pit floor left unmined due to the abrupt Covid-19 shutdown.

BHM plans a progressive expansion of the open pit into adjacent areas such as Consols South, Fishers, Rope Shaft, and Junction, targeting both existing high-grade resources and newly identified mineralisation zones. Additionally, the company is assessing underground mining potential at Pinnacles to further diversify ore feed sources.

The historical Mineral Resource Estimate for Pinnacles stands at 6.0 million tonnes grading 13.5% zinc equivalent and 374 grams per tonne silver equivalent. An updated resource estimate incorporating extensive recent drilling is expected in late 2026, which could further underpin expansion plans.

Unlocking Plant Capacity Through Multi-Source Ore Feed

BHM’s strategy of sourcing ore from multiple deposits; including Western Min, Main Lode, and Pinnacles; provides a competitive edge by optimising both ore grade and throughput. This flexibility has allowed the company to tap into substantial latent capacity at the Rasp Processing Plant, which previous operators struggled to fully utilise due to limited ore supply options.

To support the ramp-up to the plant’s full 750,000 tonnes per annum capacity, BHM has secured approval for a tailings dewatering facility. This investment aims to eliminate current inefficiencies and enable sustained higher throughput, setting the stage for further production growth.

With the combined effect of enhanced feed quality and expanded mine flexibility, BHM is well positioned to continue scaling its output in the coming quarters.
