Hancock Prospecting has agreed to invest A$8.77 million in White Cliff Minerals for a proposed 13.5% stake, giving the junior explorer fresh capital to accelerate drilling at its Rae Copper Project in Nunavut. The placement still requires shareholder approval.

Australian Rare Earths has extended its Overland carbonatite discovery roughly 5km south, with hole OV176 intersecting 130 metres of interpreted carbonatite and ending within the unit. The geological footprint now appears to track a 10km magnetic corridor, but assays will determine whether the system carries meaningful niobium and rare earth grades.

Tivan has won approval to add 50 square kilometres to its Baucau copper-gold project in Timor-Leste, securing ground over a large magnetic anomaly. The expansion comes as the company acknowledges an executive chairman’s personal X post previewed an assay announcement before ASX release and was not authorised under its disclosure policy.

Broken Hill Gold has started a 48 line-kilometre induced polarisation survey and 670 line-kilometre magnetic program at White Dam, targeting sulphide mineralisation beneath existing oxide prospects. A second diamond rig is also mobilising, but the next value test remains firmly in the ground: geophysical anomalies must translate into drilling results and an upgraded resource.

TechGen Metals has outlined a funded exploration campaign spanning gold, copper and silver targets, with about A$3 million in pro forma cash and several assays due through late 2026. The strongest potential catalyst is John Bull, where step-out drilling could support a maiden Mineral Resource Estimate if results are positive.

Tivan has secured a 50 km² exploration concession immediately north of its Turiscai project in Timor-Leste, subject to formal regulatory grant. The addition would lift the project to eight licences covering approximately 394 km² ahead of planned maiden drilling in the fourth quarter.

AngloGold Ashanti has completed a 2,659-sample soil geochemistry program at EcoGraf’s Golden Eagle project in Tanzania, with results now pending ahead of a planned drilling phase. The work forms part of a US$9 million farm-in while EcoGraf prepares separate exploration across a broader portfolio of gold and critical-minerals targets.

Raptor Metals has identified two conductive systems across its Chester copper project, including the strongest off-hole response recorded near a high-grade drill intersection. The results give the company specific targets for follow-up drilling, but the conductors remain exploration targets rather than a resource estimate.

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.

North Stawell Minerals has used a conference presentation to position Darlington and Darlington West as its leading tests of the Stawell gold model, while outlining a broader Victorian exploration pipeline. The company stresses that the drilling results and resource figures presented have been previously reported, making follow-up work rather than a fresh discovery the key investor question.

Resolution Minerals has finished its largest-ever exploration program at the Horse Heaven project in Idaho, drilling 42 diamond holes across 12,236 metres. The work sets up a substantial run of gold, tungsten and multi-element assay results, but the completed program has not yet produced new assay data in this announcement.

Great Dirt Resources has identified 24 priority manganese targets in New South Wales and confirmed rock-chip grades of up to 51.8% manganese. The exploration progress came alongside a $19.1 million FY2026 loss, largely caused by a non-cash share-based payments expense, while cash rose to $3.81 million.
