Broken Hill Mines Mobilises Two Rigs, Targets June 2026 Pinnacles Production

Operational Momentum Builds at Pinnacles

Broken Hill Mines Limited (ASX – BHM) has kicked off early works and operational readiness activities at its Pinnacles silver-lead-zinc mine, signalling a clear path toward resuming mining operations in the June quarter of 2026. The company is methodically aligning contractors, upgrading site infrastructure, and enhancing workforce capabilities to support a capital-efficient restart.

Surface works are actively improving pit access, relocating site offices away from mining zones, and removing legacy infrastructure to streamline operations and bolster safety. Meanwhile, contracts for mining services and ore haulage have been executed, providing logistical certainty for ore transport to the nearby Rasp Processing Plant, approximately 15 kilometres away.

Drilling Programs Target Resource Growth

Central to BHM’s strategy is an ambitious Phase 2 drilling program, with two rigs now mobilised on site. This program aims to significantly expand the mineral resource base and improve ore grade profiles, building on promising Phase 1 results released late last year. These earlier assays revealed high-grade mineralisation amenable to open pit mining, including intercepts with zinc equivalent grades exceeding 50% and silver equivalent grades over 1,500 grams per tonne.

The addition of a second diamond drill rig enables parallel execution of resource expansion alongside geotechnical and mine planning infill drilling. This dual approach accelerates both the growth of the resource and the delivery of critical data to inform mine design and production planning.

Optimising Ore Processing and Site Capability

Complementing drilling efforts, metallurgical test work is underway to optimise processing strategies for Pinnacles ore at the Rasp Processing Plant. This includes evaluating whether to blend ores or process them in campaigns to maximise metal recovery and concentrate quality. The outcomes will shape final operating parameters ahead of sustained ore delivery.

To support the ramp-up in activity, BHM has made targeted operational and technical hires, strengthening expertise across geology, processing, and project delivery. These appointments underpin the company’s capacity to execute its expanded drilling program and transition smoothly into mining operations.

Strategic Integration and Profit Sharing

Under a binding joint venture agreement, Broken Hill Mines holds a 70% operational profit share in the Pinnacles Mine, acting as the exclusive operator. The ore mined at Pinnacles will be transported to and processed at the company’s established Rasp Mine facility, leveraging existing infrastructure to reduce capital intensity and accelerate production timelines.

With early works progressing and key contracts in place, BHM is positioning itself to capitalise on the high-grade mineralisation at Pinnacles, potentially delivering a significant boost to its base metals portfolio in the near term.
