Highlights

  • Kingfisher Mining has commenced Reverse Circulation Drilling at its Copper Blow Copper-Gold Project near Broken Hill in New South Wales.
  • The program is designed to define the scale and continuity of the known mineralised system, with a maiden Mineral Resource Estimate as the key objective.
  • Diamond drilling is to follow the current RC campaign within three to four weeks, with multiple geophysical targets also to be tested during the program.
  • Recent drilling at Copper Blow has confirmed notable copper-gold mineralisation extending at depth and along strike, with the system remaining open in multiple directions.

Kingfisher Mining Limited (ASX:KFM) has announced the commencement of a reverse circulation drilling program at its Copper Blow Copper-Gold Project in New South Wales, near the historic mining centre of Broken Hill. The mobilisation of the RC rig marks the beginning of the next significant phase of exploration activity at Copper Blow, with a diamond drilling rig expected to follow within three to four weeks. Together, the combined RC and diamond program is designed to build towards a maiden Mineral Resource Estimate for the project.

Copper Blow — A Growing Copper-Gold System

The Copper Blow project is held through a joint arrangement between Kingfisher Mining (75%) and Broken Hill Mines (25%), and is located in New South Wales within a geological setting that has historically supported significant copper and gold mineralisation. The project sits within a broader tenure package across three proven mining districts, providing the company with exposure to a range of early-stage and more advanced prospects across approximately 700 square kilometres.

Recent drilling campaigns at Copper Blow have progressively built the case for a continuous and scaled mineralised system. Results have returned extensive copper-gold intersections including high-grade zones in the North Zone, with mineralisation confirmed at depth and along strike and the system assessed as remaining open in multiple directions. These results underpin the primary objective of the current drilling program: to establish sufficient geological data to support the preparation of a maiden Mineral Resource Estimate under the JORC Code.

The current RC program will be supplemented by a diamond drilling component focused on testing the deposit at depth and generating higher-quality core samples for geological and metallurgical characterisation. Diamond drilling provides oriented core that enables more detailed structural and mineralogical analysis, which is particularly valuable in the resource estimation process and in understanding the three-dimensional geometry of the mineralised system.

Geophysical Targets and Broader Exploration

Beyond the known Copper Blow mineralised zones, the current program will also drill test a number of priority geophysical targets identified through recent technical reviews. Several of these targets lie outside the currently defined mineralised envelope, forming part of the company's broader exploration strategy across the Copper Blow project area. Testing these targets during the current campaign provides a cost-efficient opportunity to evaluate the broader scale potential of the system before committing to additional dedicated programs.

Kingfisher Mining entered a strategic mining and processing cooperation agreement with Broken Hill Mines in early 2026, an arrangement designed to provide the Copper Blow project with access to existing mining and processing infrastructure in the Broken Hill region. For a junior explorer, access to established processing facilities can be a significant advantage — reducing the Capital requirement for development and providing a credible pathway from resource definition to production without the full cost of standalone plant and infrastructure.

The company has outlined a clear sequence of near-term milestones following the current drilling phase: receipt and reporting of assay results, integration into ongoing geological modelling, completion of preliminary metallurgical test work, and ultimately delivery of the maiden Mineral Resource Estimate for Copper Blow.

Key Insights

Commencement of drilling at Copper Blow represents a significant step in the project's progression from an exploration-stage asset towards a resource-defined project. The combination of recent high-grade drilling results, an open mineralised system, and geophysical targets yet to be tested provides a well-stocked exploration pipeline for the current campaign. The cooperation agreement with Broken Hill Mines adds an important practical dimension by potentially lowering the barrier to development once a resource is in place. Shareholders will be focused on assay results from the current program and whether the maiden Mineral Resource Estimate, when completed, meets the thresholds required to advance the project into the next stage of technical studies.
