Viridis Mining and Minerals Limited (ASX:VMM) has used its FY2026 annual report to present Colossus as a rare earths project moving from study work into execution. The company has reported strong DFS economics and fresh equity funding, but still needs key permits, binding offtake and senior debt before construction can fully proceed.

Brazilian Critical Minerals has reported striking economics for its Ema rare earths project, including a US$1.47 billion post-tax NPV, 105% IRR and six-month payback. The company’s A$7.87 million FY2026 loss, December debt maturity, permitting requirements and unresolved Drake dispute leave the development case dependent on execution and further funding.

Magnum Mining’s latest 65-hole assay batch strengthens the Plateau Zone at Piracanjuba North, where desorbable rare earth results matter more than headline grade. The company now has assays from 373 of 894 drilled holes and is targeting a maiden JORC Mineral Resource Estimate by the end of November 2026.

Karoon Energy has confirmed an electrical fault in the newly installed power cable serving Baúna’s SPS-92 well, deferring about 3,500 barrels of oil a day. The repair requires a rig-based intervention, prompting cuts to production guidance and higher unit cost forecasts for 2026.

Perpetual Resources has warned of material uncertainty over its ability to continue as a going concern after its FY2026 loss more than tripled. The ASX-listed explorer finished the year with A$2.34 million in cash, but remains dependent on further capital raisings to fund Nevada Scheelite and Brazilian exploration.

Raiden Resources posted a wider FY2026 loss after impairing A$8.86 million of exploration assets, while its cash and term deposits fell to A$11.98 million. The company is now concentrating on Brazil’s Crixás gold tailings project, Bulgarian exploration and a proposed divestment of most of Mt Sholl.

Power Minerals has repositioned around two Brazilian critical minerals projects, led by Morro do Ferro’s thick, high-grade rare earth intersections and a conceptual 10.7Mt Exploration Target. The shift comes with stronger funding and no borrowings, but the audited accounts warn that further financing remains essential.

Gold Mountain has extended reconnaissance rare earth mineralisation at its Down Under Project in Brazil to at least 13 kilometres west of the Irajuba Exploration Target. The strongest result was 10 metres at 2,145 ppm TREO, including 2 metres at 4,607 ppm, but the data remains preliminary and metallurgical recovery is still untested.

Eminence Minerals has begun field exploration across three pending licence applications at its Tayra rare earth project in Bahia, Brazil, while continuing a planned 70-hole auger campaign at Campo Grande. The work remains early-stage, with no Mineral Resource defined and Tayra’s tenure still awaiting confirmation from Brazil’s mining regulator.

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.

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.

Magnum Mining has completed more than 10,000 metres of drilling at its Piracanjuba North rare earths project in Brazil and is shifting its main effort to the 32.5km² Plateau Zone. A further 2,000-metre diamond drilling phase will run alongside independent resource, radiological and metallurgical studies, although delayed assay turnaround creates a risk to the company’s November timetable.
