Broken Hill Mines outlines up to 17.1Mt exploration target at Centenary
Broken Hill Mines has outlined an exploration target of up to 17.1 million tonnes at Centenary in New South Wales, near its operating Rasp Mine.
The target estimates possible mineralisation, rather than adding a confirmed resource, and gives a range of 13.2 million to 17.1 million tonnes.
It is in addition to an existing inferred resource of 4.8 million tonnes containing zinc, lead and silver.
The target is based on drilling and geological modelling across 1.6 kilometres, with more than 2 kilometres of northern strike still untested.
Recent drilling identified four mineralised lodes, but the new target covers only the A Lode because there is not enough information to establish continuity in the other three.
The company says Centenary’s current target and resource could contain over five times the metal produced at Rasp in 15 years, though the estimate does not mean that metal has been proven or will be mined.
Further drilling could support resource growth if it confirms continuity in the additional lodes.
Broken Hill Mines outlined a maiden exploration target of up to 17.1 million tonnes at Centenary, near its operating Rasp Mine in New South Wales.
The target is additional to Centenary’s existing inferred resource of 4.8 million tonnes.
It covers 1.6 kilometres of drilled strike, with more than 2 kilometres of untested strike to the north.
The company based the target on geological modelling and 48 drill holes, including results from its first targeted drilling campaign.
Three other identified lodes are excluded from the target because there is not enough drilling to establish their continuity.
- Who
- Broken Hill Mines, an Australian-listed mining company.
- What
- It outlined a maiden exploration target at Centenary of 13.2 million to 17.1 million tonnes, with estimated grades of 8.4% to 12.5% zinc equivalent.
- When
- The announcement was reported on 9 November 2026.
- Where
- Centenary, within Broken Hill Mines’ Rasp mining lease in New South Wales, Australia.
- Why
- Drilling and geological modelling identified a potentially substantial mineralised zone; the company says further drilling may support exploration and resource growth.
