Pinnacles Drilling Hits 1,013g/t Silver Equivalent Over 4.4m, Phase 2 Drilling Set for 25,000m
Broken Hill Mines reports outstanding high-grade silver-lead-zinc intercepts from Phase 1 drilling at Pinnacles Mine, with assays up to 1,013g/t AgEq over 4.4m. The company plans a record 25,000m Phase 2 drilling campaign in early 2026 to significantly grow its resource base.
- Phase 1 drilling at Pinnacles delivers up to 1,013g/t silver equivalent over 4.4m
- Broad shallow gold and copper mineralisation identified alongside silver-lead-zinc zones
- Maiden drilling at Perseverance underground target confirms proximity to historic high-grade intercepts
- Phase 1 (~5,800m) nearing completion with ~65% assay results pending
- Phase 2 drilling program (~25,000m) planned for Q1 2026 to expand resources and support open pit mining
Exceptional Grades Confirmed at Pinnacles
Broken Hill Mines Limited (ASX, BHM) has announced further outstanding results from its ongoing Phase 1 drilling program at the Pinnacles Mine in New South Wales. The company reported silver-lead-zinc intercepts reaching up to 1,013 grams per tonne silver equivalent (AgEq) over 4.4 metres from shallow depths, underscoring the high-grade nature of the deposit.
These results come from extension drilling in the Junction and Rope Shaft areas, which continue to demonstrate continuity of mineralisation along strike. Notably, the Junction area yielded 4.4m at 1,013g/t AgEq from just 39.1m depth, reinforcing the potential for near-surface open pit mining operations.
Gold and Copper Mineralisation Adds Value
Alongside the silver-lead-zinc system, BHM’s drilling has delineated broad zones of gold and copper mineralisation overprinting the base metal system. Highlights include 7.6m at 1.5g/t gold and 0.2% copper from 62.4m, suggesting a polymetallic deposit that could enhance project economics.
This multi-commodity potential is significant as it may provide additional revenue streams and processing flexibility when mining operations commence.
Perseverance Target Shows Early Promise
In a maiden drilling campaign at the underground Perseverance target, assays are pending but initial results indicate mineralisation near historically exceptional intercepts, including a 19.5m interval grading 1,026g/t AgEq. This area is now a priority for follow-up drilling in the upcoming Phase 2 program.
Phase 1 Nears Completion, Phase 2 Planned
Phase 1 drilling, comprising approximately 5,800 metres, is approaching completion with around 65% of assay results pending. The company anticipates sequential ASX releases over the next three to four months as assays are received.
Looking ahead, Broken Hill Mines plans to launch its largest ever drilling campaign at Pinnacles in early 2026, targeting 25,000 metres. This ambitious Phase 2 program aims to significantly increase the overall resource size and grade, underpinning near-term open pit mining decisions.
Strategic Integration with Rasp Mine Processing
The Pinnacles Mine is strategically positioned approximately 15 kilometres from BHM’s operating Rasp Mine processing plant. The company intends to truck high-grade ore from Pinnacles to Rasp for processing, leveraging existing infrastructure to accelerate project development and reduce capital expenditure.
This integration is expected to enhance operational efficiency and support a faster path to production.
Bottom Line?
With Phase 1 drilling confirming exceptional grades and Phase 2 poised to expand resources dramatically, Broken Hill Mines is setting the stage for a potentially transformative mining operation at Pinnacles.
Questions in the middle?
- How will the pending assay results from the remaining Phase 1 holes impact the updated Mineral Resource Estimate?
- What are the expected timelines and capital requirements for transitioning Pinnacles into near-term open pit production?
- How might the polymetallic nature of the deposit influence processing strategies and project economics at the Rasp Mine plant?
