Hammer Metals Advances Bullrush JV with Targeted Phase 2 Drilling
Hammer Metals Limited has launched a focused Phase 2 diamond drilling campaign at its Bullrush Joint Venture, aiming to expand on promising initial results and refine its geological model for a potential large-scale IOCG system.
- Phase 2 diamond drilling commenced at Bullrush JV targeting magnetic and gravity anomalies
- Three holes planned totaling approximately 1,450 meters
- Drilling designed to test sulphide mineralisation signatures identified in maiden program
- Assay results expected early to mid-January 2026
- Additional exploration activities planned across Hammer’s broader portfolio in coming months
Building on Early Success at Bullrush
Hammer Metals Limited (ASX, HMX) has initiated a second phase of diamond drilling at its Bullrush Joint Venture in North-West Queensland, in partnership with Sumitomo Metal Mining Oceania Pty Ltd. This follow-up program is designed to deepen understanding of the area's mineral potential after encouraging results from the initial drilling campaign.
The current program involves three diamond drill holes totaling around 1,450 meters. Two holes will focus on the flanks of magnetic anomalies that also show elevated gravity responses, while the third targets a gravity high adjacent to the Wimberu Granite margin. These geophysical features align with sulphide mineralisation characteristics previously observed, reinforcing the prospectivity of the site for iron-oxide copper-gold (IOCG) deposits.
Refining the Geological Model
Hammer Metals’ Managing Director Daniel Thomas highlighted that the maiden drilling phase successfully validated the exploration concept, confirming the presence of key geological ingredients for a large-scale IOCG system. The team has since refined their geological model, enabling the identification of new drill targets that this Phase 2 program aims to test.
Assay results from the current drilling are anticipated in early to mid-January 2026, which will provide critical data to assess the extent and grade of mineralisation. The company’s methodical approach, combining geophysical data with petrophysical analysis, underscores its commitment to systematic exploration and resource definition.
Broader Exploration Momentum
Beyond Bullrush, Hammer Metals is advancing several other projects. November and December will see drilling at Isa Valley in collaboration with South32, soil sampling results from Ken’s Bore, a comprehensive review of the Mount Isa Project’s geochemical and structural data, and follow-up drilling at Bronzewing South. These activities reflect a broad and active exploration pipeline aimed at unlocking value across the company’s extensive tenement holdings.
With a strategic position covering approximately 2,800 square kilometers in the prolific Mount Isa mining district, Hammer Metals is well placed to leverage its partnerships and technical expertise. The ongoing collaboration with Sumitomo Metal Mining, a company with centuries of mining experience, adds significant weight to the exploration efforts at Bullrush and beyond.
Bottom Line?
As Hammer Metals pushes forward with targeted drilling and refined models, the next few months will be pivotal in defining the Bullrush JV’s potential to deliver a major copper-gold discovery.
Questions in the middle?
- Will the upcoming assay results confirm the presence of economically viable IOCG mineralisation?
- How might the refined geological model influence future drilling strategies at Bullrush?
- What impact could successful exploration at Bullrush have on Hammer Metals’ valuation and partnership dynamics?
