Southern Hemisphere Mining has reported its strongest Llahuin drilling results yet, but the copper explorer ended FY26 with just $110,027 in cash and a material going-concern uncertainty. The company is relying on further funding, related-party borrowings, asset sales and a possible Chilean VAT refund to keep exploration moving.

DeSoto Resources has assembled about 1,300 square kilometres of gold tenure in Guinea’s Siguiri Basin, but the expansion came with a A$15.0 million FY2026 loss and a A$6.35 million write-off of Northern Territory exploration assets. The company enters FY2027 with drilling, geophysics and tenure renewals still to convert its large portfolio into a defined resource.

Power Minerals has outlined a maiden conceptual Exploration Target of 9.2 million to 10.7 million tonnes at Morro do Ferro in Brazil, grading 7.8% to 9.2% TREO. The result gives the ongoing drilling program a clearer target, but 43% of the upper estimate comes from an untested projected extension and nine recent holes remain unassayed.

Solstice Minerals has emerged from FY2026 with a larger exploration story, a A$45.3 million liquidity base and drilling that extends Nanadie beyond its existing resource footprint. The company remains loss-making and pre-production, leaving future value tied to resource growth and exploration execution.

Kincora Copper says 2026 drilling has identified multiple porphyry-style intrusive complexes across its Nevertire and Nevertire South licences, expanding the interpreted prospective strike beyond 40 kilometres. The results remain early-stage, but AngloGold Ashanti’s potential A$100 million earn-in gives the exploration program meaningful financial backing.

Historical work has identified widespread near-surface columbo-tantalite mineralisation at Australasian Metals’ Atex project in Côte d’Ivoire, adding a potential tantalum stream to its lithium strategy. The results are encouraging, but the underlying estimate is non-JORC, unverified and based on incomplete historical records.

Narryer Metals is buying the Redhill Copper Project in southern Chile from 29Metals, gaining an existing 4.3Mt inferred resource and a much larger conceptual exploration target. The deal also brings a A$1 million strategic investment from 29Metals at a 54% premium to Narryer’s pre-announcement share price.

Five of nine diamond holes at Minrex's Barje deposit have returned the widest and highest-grade intersections drilled there, challenging the historical model of a low-grade central corridor. The results arrive ahead of a maiden JORC resource estimate planned for next quarter.

Magnum Mining has completed a 10,000-metre auger programme at its Piracanjuba North ionic adsorption clay rare earths project in Brazil, shifting its focus to a 32.5km² plateau zone. The company is targeting a maiden JORC 2012 Mineral Resource Estimate in November, but the project remains at an early exploration stage with no declared resource or reserve.

Cannindah Resources has reported preliminary NovaCell testwork recovering 94% of copper and 92% of silver at a substantially coarser grind, while rejecting 82% of processed material. The results could support a higher-throughput, lower-energy processing route, although gold recovery and concentrate quality still require further work.

Many Peaks Minerals has extended the tested vertical depth of gold mineralisation at its Ferké project by about 70%, with a deepest intercept returning 40.3 metres at 3.89g/t gold. The results support a planned resource update and preliminary assessment of underground mining, but remain exploration results outside the current resource.

Waratah Minerals has reported its strongest drilling result to date at the Spur Gold Discovery, with a deep hole returning 46 metres at 7.27 g/t gold. The result extends the Consols Zone and supports four high-grade footwall domains, although the project remains at an early exploration stage.
