Broken Hill Mines Limited (ASX:BHM) has reported its maiden Exploration Target for the Centenary Zone at its 100% owned Rasp Mine, with a high case estimate of 17.1Mt at 12.5% ZnEq and 432g/t AgEq, containing 2,137kt ZnEq and 246.1Moz AgEq, in addition to the existing Centenary Mineral Resource Estimate of 4.8Mt at 9.2% ZnEq.

Key Points

Maiden Exploration Target high case: 17.1Mt at 12.5% ZnEq, 432g/t AgEq, containing 2,137kt ZnEq and 246.1Moz AgEq; low case: 13.2Mt at 8.4% ZnEq, 291g/t AgEq, containing 1,109kt ZnEq and 127.7Moz AgEq
Exploration Target covers 1,600m strike length, fully constrained by drilling, and remains open with over 2,000m of untested strike to the north
Existing Centenary MRE (Inferred) stands at 4.8Mt at 9.2% ZnEq, 255g/t AgEq, containing 443kt ZnEq and 49.2Moz AgEq, separate from the Exploration Target
Centenary Zone is located approximately 250m from current operations feeding the 750,000tpa Rasp Processing Plant within the Rasp Mining Lease
BHM has begun a staged program of Centenary development, with new exploration drives underway, and a Rasp Mine MRE update due to be released at the end of 2026

Centenary Exploration Target Parameters and Basis

The Exploration Target is underpinned by 48 drill holes that intersected Centenary mineralisation, including historical drilling by Zinc Corporation Ltd and MMM Ltd between 1980 and 1995, additional drilling by CBH Resources from 2012 to 2024, and drilling completed by BHM in 2026. The target is based on a single defined Centenary lode only, with average true widths of 12 metres. Recent drilling has also intersected three additional non-continuous lodes within the Centenary Zone. The target has been prepared in accordance with the JORC Code (2012). The potential quantity and grade are conceptual in nature, and it is uncertain whether further exploration drilling will result in estimation of a Mineral Resource.

Key Drilling Intercepts Supporting the Centenary Discovery

BHM's maiden Centenary drill program has delivered multiple high-grade intercepts. Highlights include 20.2m at 17.7% ZnEq and 488g/t AgEq from 1,156m in hole WMDD5859W2, 25.8m at 11.7% ZnEq and 323g/t AgEq from 415m in hole WMDD6391, and 10.4m at 20.5% ZnEq and 567g/t AgEq from 799m in hole WMDD6067W2. The drilling program represents the first ever targeted drilling below the Globe-Vauxhall Shear, delivering thick, high-grade intercepts across a significant strike in areas with little or zero previously modelled grade. The current defined Centenary lode is interpreted to be the geological equivalent of the historic A Lode, one of the principal mineralised units of the Broken Hill Line of Lode.

Naming of Plimer A Lode and Near-Term Development Activities

BHM disclosed it will name Centenary's A Lode the "Plimer A Lode" in honour of more than 50 years of geological service to Broken Hill by Professor Ian Plimer, who is also a Non-Executive Director of the company. BHM has commenced a staged program of Centenary development, with new exploration drives underway for an expedited drill-out of the Centenary Zone over the course of FY27. Current drilling results will contribute to Centenary's Mineral Resource Estimate, which is scheduled to be upgraded as part of BHM's Rasp Mine MRE update, to be released at the end of 2026.
