Broken Hill Mines Records Best Quarterly Since Rasp Acquisition and Pinnacles Restart

Broken Hill Mines (ASX: BHM) has reported its strongest quarterly performance since acquiring the 750,000-tonnes-per-annum Rasp processing plant in New South Wales and restarting operations at the Pinnacles mine.

The company posted a record quarterly throughput to the end of June of 119,320 tonnes processed, representing a 3.2% increase on the previous quarter and the highest volume processed since mid-2020.

Silver production rose 21.8% on the previous quarter to 95,787t, Rasp’s best quarterly performance for the metal since September 2022, while zinc production of 3,330t was up 7% and the highest return since March 2025.

June also saw Broken Hill’s strongest four-week performance with a total 50,075t processed at a 5.6% combined lead-zinc grade and 38 grams per tonne silver for 49,700oz silver, 1,075t lead, and 1,380t zinc.

Important Strategic Step

The increase follows the successful start of operations from the high-grade Main Lode, which will ramp-up from the September quarter.

Pinnacles also contributed its first ore feed during the period after Broken Hill recommenced operations at the mine, which was placed on care and maintenance in 2021 following operational constraints during the global pandemic.

The Pinnacles restart represents an important step in Broken Hill’s strategy to fully utilise the Rasp plant, located 15 kilometres away.

Initial operations are focused on expansion of the existing Edwards pit, which is open laterally and at depth to minimise the strip ratios normally associated with first production from a pit and enable access to up to 50,000t of high-grade ore in the pit floor.

Output from Edwards is scheduled to progressively ramp up over the coming months, capitalising on significant high-grade silver-lead-zinc intercepts released over the last 12 months and building on historical operations at Pinnacles that focused on the extraction of silver and lead only.

Updated Pinnacles MRE

Broken Hill has planned an update before year end of the Pinnacles mineral resource estimate (MRE), which sits at 6Mt grading 13.5% zinc equivalent and 374g/t silver equivalent (132g/t silver, 3.3% lead, and 4.7% zinc).

It is also planning a progressive expansion of the Edwards open pit into the Consols South, Fishers, Rope Shaft, and Junction areas, targeting existing high-grade resources and expanded mineralisation zones shown through recent drilling results.

The company believes there is strong potential for high-grade underground operations to be developed at Pinnacles.

Broken Hill is currently assessing options to form an additional ore feed for the Rasp plant, with a multi-source strategy seen to provide significant competitive advantage in the optimisation of both grade and throughput.
