Highlights

The company operates the Rasp silver-lead-zinc mine in Broken Hill.
Rasp has an established processing plant with stated capacity of 750,000 tonnes annually.
2026 disclosures discuss mineralised intersections in the Centenary zone.
Pinnacles forms a separate resource and development opportunity.

Broken Hill Mines Limited, formerly known as Coolabah Metals Limited, operates in the silver, lead and zinc Mining sector in Broken Hill, New South Wales. Its company website identifies the Rasp Mine as an operating underground mine and the nearby Pinnacles asset as part of its development programme.

Existing Mining and Processing at Rasp

The Rasp Mine is situated within the Broken Hill mineral district and produces lead-silver and zinc concentrates using underground mining and flotation processing. The company’s website describes grinding, flotation, thickening and filtration infrastructure, supported by existing road and rail links. This operating system is an important distinction from a company relying entirely on early-stage exploration.

Broken Hill Mines Limited (ASX:BHM), previously Coolabah Metals Limited (ASX:CBH), reports a Rasp mineral resource estimate of 10.1 million tonnes grading 9.4% zinc equivalent. That estimate is a mineral-resource measure, not a statement that the entire tonnage is economically recoverable. The published plant capacity of 750,000 tonnes per annum likewise represents processing design capability, not a verified 2026 throughput total.

The Centenary Zone and 2026 Drilling

A 2026 Quarterly Report describes drilling at the Centenary zone within the Rasp area. Reported intercepts include 25.8 metres at 11.7% zinc equivalent from around 415 metres and 17.8 metres at 10.1% zinc equivalent from around 420 metres. These are downhole drill results and should not be described as ore reserves or automatically converted into mineable tonnes.

The company indicated that Centenary assessment remained an active workstream, including further resource-related evaluation. Geological continuity, mining access, dilution, metallurgy and engineering will all affect how additional mineralisation might contribute to mine planning. For Broken Hill Mines Limited (ASX:BHM), the 2026 results provide evidence of exploration activity around an established mine, but development decisions require more than favourable individual intercepts.

Pinnacles and Capital Allocation

Pinnacles is located near Broken Hill and is presented by the company as a separate silver-lead-zinc mineral resource. Its website describes a mineral resource estimate of 6.0 million tonnes at 10.9% zinc equivalent. That figure helps define the scale of the reported inventory but is not a production target.

The company’s 2026 quarterly report also outlined an AUD 85 million two-tranche placement, with funds intended for the Centenary production decline, resource drilling, infrastructure and Pinnacles work. The report stated the second Tranche was completed in October. Funding capacity supports planned work but does not remove execution, approval or commodity-price risks.

Operational and Reporting Considerations

Underground mining at Broken Hill entails geotechnical controls, ground support, ventilation, grade reconciliation and management of tailings and rehabilitation. Processing results depend on ore blend, recoveries, plant availability and concentrate Marketing arrangements. These factors make a mine’s annual processing capacity only one of several important measures.

Broken Hill Mines Limited (ASX:BHM) also needs to manage Capital Expenditure and working-capital requirements while conducting exploration. Its different mineral zones should be evaluated using the specific technical confidence categories disclosed for each resource. Statements about future mine life or profitability cannot be inferred solely from the existence of historical workings or new drill intercepts.

Key Insights

The company’s 2026 activities connect the operating Rasp processing platform with Centenary drilling and the Pinnacles development programme. For the enterprise formerly named Coolabah Metals Limited (ASX:CBH), current mine performance, resource definition and capital deployment are separate measures. Each requires dated operational and financial reporting rather than assumptions drawn from resource size alone.
