Patronus Resources has struck a 44-metre gold interval at its Hydra target in the Northern Territory, with the hole ending in mineralisation and follow-up drilling brought forward. Early results from Grove Hill also returned gold, but the wide-spaced campaign remains far from defining a resource.

Cosmo Metals has contracted Durock Drilling for up to 2,200 metres of maiden reverse-circulation drilling at the Mona prospect in New South Wales. The campaign will test whether exceptional copper, gold and silver grades from historic mine dumps reflect mineralisation continuing beneath the old workings.

Castile Resources has emerged from FY2026 with a larger Rover 1 resource, stronger preliminary project economics and A$9.37 million in cash. The next challenge is converting a A$1.07 billion pre-tax NPV8 study into a funded, permitted mining project.

Metals Australia has reported a 50 Mt graphite resource, a maiden 21.51 Mt probable ore reserve and strong study-stage economics for its Quebec project. The opportunity is substantial, but the company ended the year with just AUD 3.73 million in cash and no mining revenue.

Catalina Resources has executed the mining lease transfer for its Nelson Bay River project, paving the way for up to $1.29 million in rehabilitation security to be recovered. The company plans to redirect the capital into November drilling at its Kirkalocka gold and Tallering tungsten projects, subject to final heritage clearance and regulatory steps.

Antipa Minerals has extended gold-copper-lead-silver mineralisation across 2.2km at Tim’s Dome, sharpening focus on a large untested electromagnetic conductor. Surface diamond drilling is now underway on the 1.2km target, which remains unproven despite encouraging surrounding assays.

Right Resources has begun a fully funded 2,000-metre aircore program at its Blue Prospect near Tumbarumba, testing six tungsten and five gold anomalies for the first time below surface. Assay results are expected progressively during the December Quarter, but the campaign is exploratory and is not designed to define a Mineral Resource.

Eastern Resources has placed its Queensland Marengo Gold Project at the centre of its exploration strategy after 54 of 60 rock-chip samples returned more than 0.1 ppm gold, including a peak of 12.3 ppm. The company remains an early-stage explorer, with no JORC Mineral Resource yet defined and A$3.27 million in cash at year-end.

Mt Malcolm Mines has identified four copper-gold exploration targets across its Malcolm Project, led by selective Braiser rock chips grading up to 1.37% copper. The broader target inventory is promising but remains early-stage, with no new drilling completed and most geochemical signals still awaiting laboratory verification.

Great Northern Minerals has identified at least three undrilled chargeability anomalies at its Douglas Creek project in North Queensland, supported by gold, copper, silver and bismuth surface results. The targets sit around a large reverse-polarised magnetic tonalite body that extends to an interpreted depth of about 1 kilometre, but drilling is not expected until mid-2027.

Evolution Energy Minerals has moved its Chikundo Copper Project from surface exploration to subsurface testing, with a 3,350-metre reverse circulation campaign now underway in southern Tanzania. The programme will first target the Malachite Pit and main Chikundo anomaly before optional holes assess three additional prospects.

Cosmo Metals has secured approval for up to 2,200 metres of maiden drilling at the Mona copper-gold-silver prospect in New South Wales. The campaign will test whether striking grades from historic mine dumps reflect concealed sulphide mineralisation below the old workings.
