Latest Copper Exploration News

Cosmo Metals has secured the Carters Road exploration licence in New South Wales after reconnaissance work returned 4.69% copper and 5.78g/t silver from a single selective rock-chip sample. The result offers an early exploration lead, but does not establish continuity, scale or economic significance.

Golden Horse Minerals has expanded the interpreted Hopes Hill gold system beyond 3 kilometres after completing 52,762 metres of drilling in the six months to June 30. The exploration push delivered multiple high-grade intersections and free-milling metallurgy, but came with no revenue, a $4.37 million loss and a sharp drawdown in cash.

Cazaly Resources has refined two magnetic targets at its Abenab North project in Namibia, clearing the way for planned maiden drilling of potential rare earth, copper and base-metal mineralisation. A third target, Cadix, has been downgraded after historic mapping errors were identified.

Green & Gold Minerals (ASX:GG1) is raising $3.2 million through a 1-for-2 renounceable rights issue priced at 10 cents per share to fund aggressive drilling programs targeting copper-silver-tin at Herberton and gold resource expansion at Chillagoe's Mt Wandoo.

True North Copper is expanding its Mt Oxide copper district with the Aquila-Chidna discovery now stretching over 2.3km, while progressing a prefeasibility study at Cloncurry due late 2026.

Javelin Minerals has launched a significant diamond drilling campaign targeting two major deep gold-copper anomalies at its Coogee Project in WA, supported by WA Government funding.

AusQuest’s latest diamond drilling at the Cangallo project in Peru pushes copper mineralisation down to at least 800 metres and reveals multiple higher-grade zones, reinforcing the scale of this emerging porphyry system.

Middle Island Resources has unveiled substantial copper anomalies at its Jelaca and Oglavak prospects within the Priboj Project, bolstering its volcanogenic massive sulphide exploration thesis.

White Cliff Minerals has expanded the ultra high-grade Danvers 3 copper zone at its Rae Project, hitting a new peak assay of 23.5% copper and extending the mineralised strike to over 220 metres. Follow-up drilling aims to unlock further growth across the emerging copper system.

Pacific Resources has confirmed a new high-grade copper zone at its Dogwood project, with assays revealing the highest copper grade recorded to date alongside a first-ever polymetallic porphyry signature from laboratory tests.

True North Copper (ASX:TNC) has expanded its Mt Oxide copper-cobalt-silver system to a 2.3km strike length, unveiling a new ~300m wide mineralised zone at Chidna alongside multiple high-grade shoots at Aquila.

PolarX Limited has intersected significant massive sulphide copper mineralisation in new zones approximately 60m west of the existing Caribou Dome resource in Alaska, potentially expanding the known deposit. Drilling by the Alaska Range Joint Venture with Northern Star continues, with assays expected in October 2026.
