Key Highlights

  • Hamelin reported first assays from 22 of 35 holes in its Phase 2 drilling program at Day Dawn.
  • PLC identified priority gold targets across its Abbotts Gold Project using satellite and magnetic data.
  • Aurelia extended copper and gold lenses at the Peak South Mine in the Cobar District.
  • Several companies outlined further assays and drilling expected in the coming weeks.

Hamelin Gold Limited (ASX:HMG), PLC Resources Limited (ASX:PLC) and Aurelia Metals Limited (ASX:AMI) each provided exploration updates on 27 October 2026. The announcements cover gold drilling in Western Australia, satellite-based target generation over a Murchison project and underground exploration at a copper-gold mine in New South Wales.

Latest Developments

Hamelin reported the first assays from its Phase 2 reverse circulation program at the Day Dawn gold project in the Paterson Province. Results from the first 22 of 35 holes, drilled over about 4,000 metres, included 2 metres at 101.5g/t gold within a broader 11-metre zone at 20.2g/t on the Altus Lode. The company said deeper drilling extended the Aurora Lodes at depth and that a maiden 1,500-metre diamond program has started. Assays for the remaining 13 holes are expected in November 2026.

PLC Resources said satellite geo-spectral work over its Abbotts Gold Project, about 35 kilometres north of Meekatharra, defined priority gold targets. The EnMAP hyperspectral survey covered about 205 square kilometres, and the first-priority targets include Rochefort, Buttamiah, Vranizan North and Sprigg Bore. Field verification is planned this quarter, with aircore drilling targeted to begin in the first quarter of 2027, and assays from an eight-hole, 1,896-metre reverse circulation program at Rochefort are expected in the coming weeks.

Aurelia Metals reported exploration results from the Peak South Mine. Drilling between the Peak and Kairos deposits returned 10 metres at 113.3g/t gold and 1.3% copper from 58 metres, while the Kairos Eastern Copper Lens was extended 100 metres to the north and 80 metres down-dip. Copper grades were also intersected in Perseverance Zone A, which was extended 30 metres along strike and up-dip.

Sector Context

Gold and copper exploration in Australia increasingly relies on combined datasets, including satellite imagery, airborne magnetics and underground drilling, to narrow drilling targets before costly programs begin. The three companies show different stages of this process, from target generation at Abbotts to drill-testing at Day Dawn and underground definition at Peak South.

The three companies also illustrate how exploration tools are being combined. Target generation through satellite and magnetic data at Abbotts sits alongside conventional reverse circulation and diamond drilling at Day Dawn, while underground drilling at Peak South provides geological detail that surface work cannot easily achieve. Investors often look for consistency between early targeting and later drill results, and the coming assays from each company will test how well those early interpretations hold up.

Risks to Consider

Exploration results are preliminary and may not be repeated in later drilling. Target generation from satellite and geophysical data does not confirm mineralisation, and field verification may change priorities. Aurelia's copper and gold lenses are still being defined and may not convert into a mineral resource update. Each company also faces funding requirements, approval timelines and the cost of ongoing drilling.

What to Watch Next

Investors may follow Hamelin's remaining 13 Phase 2 assays and early results from its diamond program, PLC's Rochefort assays and first field verification, and Aurelia's upcoming drilling at Kairos and Perseverance Zone A.

Final Word

The three updates illustrate how exploration programs move from targeting to drilling to mine-scale definition. Each company's next release will show whether the current intercepts and target areas expand further, and readers can follow those announcements to track progress.
