Highlights
Newly assayed historical drill holes confirm high-grade silver-lead-zinc mineralization.
The mineralization supports open pit and underground development possibilities.
Ongoing efforts include additional assays and an infill drilling program to refine resource definition.
The mining sector continues to unveil substantial resource discoveries, with Broken Hill Mines reporting noteworthy assay results from historical drill holes at the Pinnacles Mine. Situated near Broken Hill, known as the ‘Silver City,’ the site presents considerable silver-lead-zinc mineralization. This development strengthens the company’s position in mineral exploration and resource expansion at Pinnacles Mine, in which it holds a controlling interest.
Assay Results and Resource Implications
Analysis of historical drill holes has revealed extensive mineralized zones containing high-grade silver, lead, and zinc. Among the results, one section measured over eight meters with a zinc equivalent exceeding thirty-six percent, accompanied by high silver content. Additional drill intersections confirm similarly rich mineralization, supporting assessments for open pit feasibility while reinforcing subsurface resource continuity.
Geological Composition and Exploration Strategy
The mineralized system at Pinnacles comprises a lead-rich lode carrying significant silver values, along with a parallel zinc-dominant structure. These formations also feature sporadic copper and gold traces. To advance resource evaluation, Broken Hill Mines is conducting extensive geological logging and quality assessments of archived drill core samples. An infill drilling program is scheduled to refine the delineation of shallow mineralization, a step that could contribute to early-stage resource extraction planning.
Operational Prospects and Development Planning
The Pinnacles Mine is positioned to complement ore supply to the nearby Rasp mine processing plant. The presence of high-grade mineralized zones at shallow depths enhances the scope for extraction methods suited to both surface and underground mining. Current efforts focus on optimizing geological interpretations and confirming continuity in mineralization to inform future operational decisions.
Strategic Considerations for Resource Utilization
By further analyzing historical drill data and initiating targeted exploration, Broken Hill Mines is advancing toward a structured resource assessment approach. The Pinnacles site holds significance due to its proximity to existing mining infrastructure and historical production areas. The combination of new assay results with previous geological insights supports continued evaluation of resource extension possibilities.
