High-Grade Gold Confirmed at Bronzewing South

Hammer Metals Ltd (ASX: HMX) (“Hammer” or the “Company”) is pleased to provide an update on recent exploration progress at its 100%-owned Yandal Gold Project in Western Australia. Diamond drilling continues with the first batch of assays now received for the zone of visible gold reported to the ASX on 2 September 2025. Drilling of the diamond tail to drill-hole BWSRCD081 was completed a depth of 561.7m.

The diamond drilling program has continued with two diamond tails completed at the Bronzewing Central Target, located approximately 1.7km to the south of the Eastern Target Zone. A follow-up diamond tail will commence shortly at the Eastern Target, with drilling anticipated to conclude towards the end of September. Results from this program will continue to be submitted to the laboratory in batches, with results anticipated to be received throughout September and into mid-October.

• Partial results received from the diamond tail of drill-hole BWSRC081 with the visible gold zone returning 15.5g/t Au over 0.48m from 416.5m. This high- grade zone is reported within a broader intercept of:
  
  • 8.95m at 1.32g/t Au from 414m, including:
    
  • 0.48m at 15.5g/t Au from 416.5m; and
    
  • 0.55m at 3.52g/t Au from 422.4m.
    
• Follow-up drilling along strike from these intercepts is scheduled to commence in the coming days to define the extent of the south-trending zone of gold mineralisation with a diamond tail of drill-hole BWSRCD086.
  
• Drill results indicate the inadequacy of historical air-core drill testing with a significant search space now open on the boundary with the historical Bronzewing Mining Lease.
  
• Diamond drilling at the Central Target, located ~1.7km to the south of the Eastern Target and within the same structural corridor, has encountered zones of intense locally massive quartz veining associated with brecciation below historical Hammer gold drilling anomalies of:
  
  • 20m at 1.5g/t Au from 120m in drill-hole BWSRC0037, including:
    
  • 8m at 2.4g/t Au from 120m; and
    
  • 4m at 3.9g/t Au from 120m.¹
• Assay results from the remaining program will be progressively released in the coming weeks.

Hammer’s Managing Director, Daniel Thomas, said:

“The confirmation of high-grade gold mineralisation at Bronzewing South is a significant step in our search for an economically viable gold target at our Yandal Gold Project. High-grade mineralisation can be traced with multiple intercepts to the north of our project area, with the mineralised structure interpreted to extend for hundreds of metres.

“We will now look to test this structure approximately 100m further south on our project area. We are very much looking forward to follow-up drilling at the Eastern Target, as we enter a zone without any previous drilling coverage.

“The team is encouraged by the observations in recent drilling at the Central Target and the potential for this corridor to be connected to the Eastern Target drilling some 1.7km to the north. This corridor is largely untested below the ineffectual air-core drilling and, with a prominent shear zone interpreted to connect these targets, it is of high interest to the team in our search for a significant gold discovery.”
