- March 2026 quarter silver production up 51.7%
- Lead and zinc outputs increased by 48.5% and 7.9% respectively

Quarterly Production Growth at Rasp Mine
Broken Hill Mines Limited (ASX:BHM) has reported a notable increase in production at its Rasp silver-lead-zinc mine for the March 2026 quarter. The company processed 115,653 tonnes of ore, a 3.6% increase from the previous quarter. Silver output rose sharply by 51.7% to 78,649 ounces, while lead production increased by 48.5% to 2,473 tonnes. Zinc production also grew by 7.9% to 3,113 tonnes.
The company has indicated that full March quarter production and financial results will be released in late April following customary reconciliation processes. These figures reflect the ongoing ramp-up of the 750,000 tonnes per annum processing plant at Rasp, supported by the introduction of additional ore feeds.
Ore Feed Diversification Strategy
BHM is advancing its strategy to diversify ore sources feeding the Rasp processing plant. Alongside the long-term Western Min ore supply, the company has successfully established operations at the Main Lode ore body, with plans to materially increase stoping ore volumes in the June and September quarters. Additionally, the Pinnacles Mine is on schedule to commence ore feed to the plant in the June quarter.
This 'Hub & Spoke' model, incorporating multiple ore sources including Western Min, Main Lode, and Pinnacles, aims to optimise processing plant utilisation and support production growth. The Pinnacles Mine, in particular, has been the focus of recent exploration success, with high-grade silver-lead-zinc mineralisation reported in previous announcements.
Mining Lease Renewal and Exploration Licence Grants
In a significant development for its operational horizon, BHM has secured a renewal of its Consolidated Mining Lease 7 (CML7) and Mining Purposes Leases MPL 183–186, extending their expiry dates to 2047. This renewal secures the company's rights to operate its flagship Rasp Mine and associated infrastructure for the next two decades.
Furthermore, new exploration licences ELA6996 and ELA6997 have been granted and converted to EL9881 and EL9882, respectively, with expiry dates set for 17 March 2032. These licences are held by Kingfisher Mining Limited (ASX:KFM), with BHM participating through an existing joint venture agreement. This arrangement supports ongoing regional exploration and potential growth opportunities around the Rasp operations.
Context and Outlook
The reported production increases and lease renewals align with BHM’s broader strategy to ramp up processing capacity and secure long-term operational stability. The company’s progress with the Main Lode and Pinnacles ore bodies follows recent exploration successes, including high-grade intercepts at Pinnacles reported in March 2026. These developments suggest a focus on expanding ore supply sources to sustain and potentially grow production levels.
While the full financial impact of these operational changes will become clearer upon the release of detailed quarterly results, the lease renewal provides regulatory certainty for BHM’s flagship asset. The joint venture with Kingfisher Mining further indicates a collaborative approach to regional exploration, which may influence future resource development.
Bottom Line?
BHM’s production growth and lease renewal extend its operational runway, but forthcoming financial results will clarify the full impact of these developments.
Questions in the middle?
- How will the ramp-up of Main Lode and Pinnacles ore feeds affect overall production and costs in coming quarters?
- What financial implications will the lease renewal and expanded exploration licences have on BHM’s valuation?
- How might the joint venture with Kingfisher Mining influence regional exploration success and resource expansion?
