# Centenary Zone reaches new heights as BHM confirms silver-lead-zinc discovery Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/centenary-zone-reaches-new-heights-as-bhm-confirms-silver-lead-zinc-discovery--5065f97c-0bbf-46c8-9697-8e505fae58ee Original source: https://stockhead.com.au/resources/centenary-zone-reaches-new-heights-as-bhm-confirms-silver-lead-zinc-discovery/ Publisher: stockhead Original announcement: 2026-08-17T02:35:09.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Broken Hill Mines - Ticker: BHM - Exchange: Unavailable - Region: New South Wales - Primary commodity: Silver - Secondary commodities: Lead, Zinc, Copper - Document categories: Drill results, Other - Extracted: 2026-08-20 17:25:58 UTC Narrative sentiment: 0.90 · Bullish ## Minestarters Atlas summary Broken Hill Mines has reported high-grade silver, lead, and zinc drill intercepts at the Centenary Zone of the Rasp mine. The results include intercepts of up to 540 g/t silver equivalent and represent a major discovery that extends the known mineralisation strike to approximately 1600m. Reasoning: Significant high-grade silver-lead-zinc intercepts reported that extend beyond the existing resource boundary and connect previously separate portions of the Centenary Zone. - Positive factor: high-grade intercepts - Positive factor: step-out extension beyond resource boundary - Positive factor: strike length continuity - Positive factor: bulk-tonnage potential Facts used in scoring: 20 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Intercepts are reported beyond the existing resource boundary. Evidence · text > Broad intercepts of high-grade silver, lead and zinc beyond Broken Hill Mines’ \(ASX:BHM\) resource boundary **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Silver intercept of 173 g/t is exceptionally high for the context. Evidence · text > high-grade silver intercepts of up to 173g/t ## Extracted facts Stored fact records: 20.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
