Middle Island Resources has outlined a much larger Serbian exploration portfolio after acquiring Konstantin Resources, with Bobija emerging as a broad shallow gold-silver polymetallic system. But the ASX explorer also reported a $3.35 million loss, $2.39 million in cash and an auditor-flagged material uncertainty over its ability to continue without further capital.

Australian Gold and Copper has reported repeated broad zinc-gold-lead intersections at northern Evergreen, including a peak interval of 26.4% zinc. A 21-hole, 2,593-metre RC program has also finished testing extensions to the prospect’s recent high-grade gold-silver discovery, with assays due from late October to early November.

Advance Metals has recorded its strongest silver assay yet at the Gavilanes Project in Mexico, with drilling also returning the project’s highest-grade zinc-lead interval. The mineralised system remains open at depth and to the southwest, while metallurgical work and further drilling target a maiden JORC resource in the December quarter of 2026.

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.

Diablo Resources has exercised its option over 101 patented claims covering the historic Horn Silver Mine in Utah, bringing its broader 202-claim, 13.2 square kilometre project package together. The company will now rank targets, advance permitting and prepare for a maiden Horn Silver drilling program in 2026.

Catalina Resources is gearing up for maiden drilling at its Tallering Santy target in November 2026 while pushing Kirkalocka towards drill-ready status and launching first-ever fieldwork at Warriedar.

Diablo Resources has delivered exceptional first-pass rock sampling results at its Horn Silver Project in Utah, revealing a district-scale polymetallic system rich in silver, gold, copper, lead, and zinc. These findings reinforce historical structural models and set the stage for imminent drilling campaigns.

Australian Gold and Copper Ltd (ASX: AGC) has reported extensive polymetallic mineralisation at its Evergreen Prospect, delivering high-grade gold, silver, lead, and zinc intercepts. With 17 diamond holes completed and a reverse circulation rig now targeting shallow oxide zones, the company is progressing towards an initial Mineral Resource Estimate.

Green & Gold Minerals (ASX:GG1) has revealed significant copper, silver, and tin mineralisation at its Elizabeth Bluffs prospect within the Herberton Conductor Metals Project, supported by historic data and recent sampling. A 3,000m drill campaign at Mt Wandoo is set to commence in September 2026, aiming to extend high-grade gold-silver zones.

QEM Limited’s review of the Big It Tungsten Project in Idaho reveals significant untapped high-grade tungsten, antimony, and gold mineralisation with extensive underground workings, setting the stage for a modern exploration campaign amid strategic supply concerns.

Catalina Resources has uncovered a promising intrusion-related tungsten-polymetallic system at its Tallering Project in Western Australia, highlighted by strong W-Mo-Bi mineralisation and a priority drill target from an untested eastern IP anomaly.

Broken Hill Mines (ASX: BHM) has delivered a suite of high-grade silver, lead, zinc, copper, and gold intercepts from recent drilling at its Pinnacles Mine open pit area, underpinning ongoing mining operations and a planned resource upgrade by year-end.
