Broken Hill Mines Limited has intersected wide, high-grade silver, lead and zinc mineralisation at the Centenary Zone within the Rasp Mine in New South Wales, confirming a major new discovery located approximately 250 metres from existing operations.

Drilling below the Globe-Vauxhall Shear used an innovative cased-hole technique to navigate the shear structure without drill-bit distortion, allowing the team to test the target area successfully. Assay results from hole WMDD6400W1 returned 17.8 metres at 10.1% zinc equivalent and 280 grams per tonne silver equivalent from 420 metres. That interval included a 5.4-metre section grading 19.5% zinc equivalent and 540 grams per tonne silver equivalent from 432.4 metres, with silver grades reaching 173 grams per tonne.

A second hole, WMDD6391W1, intersected 14.1 metres at 9.4% zinc equivalent from 394.8 metres, alongside 11.1 metres at 9.0% zinc equivalent from 420 metres. The new drilling connects the northern and southern portions of the Centenary Mineral Resource Estimate across a strike length of roughly 1,600 metres.

Broken Hill Mines holds a 100 percent interest in the Rasp Mine located in Broken Hill. Development of the Centenary Zone is designed to feed the company's 750,000 tonnes per annum operational processing plant at the mine.

Visual inspection of a subsequent drill hole, WMDD6389A, completed between the previous intercepts, indicates a further mineralised zone up to 35 metres thick. Laboratory assays for WMDD6389A are pending and expected in four to six weeks.

The company is currently undertaking additional drilling into the Centenary Zone to define the discovery further and delineate an Exploration Target. An upgrade of the Centenary Zone Mineral Resource Estimate at the Rasp Mine is targeted for the fourth quarter of calendar year 2026.
