Broken Hill Mines (ASX:BHM) holds a 25% interest in the Copper Blow Copper-Gold Project (EL9840) near Broken Hill, New South Wales, where joint venture operator Kingfisher Mining Limited (ASX:KFM) has commenced reverse circulation drilling as part of an approximately 3,500-metre combined RC and diamond drilling program aimed at advancing the project towards a maiden Mineral Resource Estimate.

Key Points

RC drilling has commenced at the Copper Blow Copper-Gold Project, with a diamond drill rig expected to follow in 3–4 weeks.
The program comprises approximately 3,500 metres of combined diamond and RC drilling.
The Copper Blow project is held 75% by Kingfisher Mining and 25% by Broken Hill Mines under exploration licence EL9840.
Recent drilling returned results including 26m @ 2.57% Cu and 0.75g/t Au from 73m and 43m @ 1.32% Cu and 0.32g/t Au from surface.
The program will also test priority geophysical targets located outside the currently defined mineralised zones.

Drilling Program Scope and Objectives

The current drilling program at Copper Blow has been designed to define the scale and continuity of the known mineralised system. Planned drill holes will test interpreted extensions to mineralisation at depth and along strike. The mobilisation of the RC drill rig marks the commencement of the next phase of work, with a diamond drill rig to follow within 3–4 weeks. The key objective of the program is to advance the project towards a maiden Mineral Resource Estimate. The filing states the mineralised system remains open both at depth and along strike, based on results from recent drilling programs.

Recent Drilling Results at Copper Blow

The filing discloses several results from recent drilling programs at Copper Blow that informed the design of the current program. These include 13m @ 1.2% Cu and 0.26g/t Au from 23m, including 4m @ 3.43% Cu and 0.74g/t Au from 23m (25CBRC_073); 26m @ 2.57% Cu and 0.75g/t Au from 73m, including 13m @ 4.07% Cu and 1.20g/t Au from 75m (26CBRC_081); 43m @ 1.32% Cu and 0.32g/t Au from surface, including 17m @ 2.46% Cu and 0.60g/t Au from 16m (26CBRC_080); and 58m @ 0.67% Cu and 0.15g/t Au from 165m (26CBRC_082A). These results were previously reported in the filing dated 14 July 2026.

Planned Next Steps Including Metallurgical Test Work and Resource Estimate

According to the filing, planned work following the current drilling phase includes receipt and reporting of assay results, integration of drilling and assay results into ongoing geological modelling, and completion of preliminary metallurgical test work to support ongoing project evaluation. The company has also disclosed plans to deliver a maiden Mineral Resource Estimate for Copper Blow, undertake continued assessment and ranking of priority exploration targets from recent geophysical reviews, and define and plan future exploration drilling programs across the broader Copper Blow project area. The filing notes a mining and processing co-operation agreement with Broken Hill Mines was entered on 4 March 2026.
