Jupiter Mines delivered above-target production and sales at its Tshipi manganese mine in FY26, but higher costs and a stronger South African rand pulled group profit lower. The year also brought a new majority co-investor, a leadership transition and fresh questions around the mine’s resource and reserve base.

Jupiter Mines will replace Managing Director Brad Rogers with mining veteran Matthew Jarvis on an interim basis, while Rogers remains through November to oversee key strategic outcomes. The transition gives the company continuity, but leaves the timing of a permanent appointment unresolved.

OM Holdings returned to profit in the first half of 2026 despite a 14% revenue decline, with EBITDA rising sharply and debt reduced through repayments and an asset sale.

OM Holdings reversed a loss to report a US$26.3 million profit in 1H 2026, driven by a major asset disposal and improved product margins despite lower sales volumes.

Ragusa Minerals has pinpointed 14 priority drill targets at its historic Black Rock Manganese Mine site in Arizona, following a detailed induced polarisation survey that reveals significant extensions of high-grade manganese mineralisation.

Estrella Resources has identified multiple high-conductivity anomalies at its Ira Miri project via a novel UAV geophysical survey, prompting plans for the deepest mineral exploration drilling ever in Timor-Leste starting September 2026.

OM Holdings' subsidiary OM Materials has locked in a binding take-or-pay deal to purchase up to 1.1 million tonnes per annum of manganese concentrate from Element 25's Butcherbird Mine, underpinning Element 25's expansion and financing plans.

Great Dirt Resources has sharpened its lithium exploration focus in the Pilbara while confirming high-grade manganese assays in NSW, maintaining a robust cash position to fund its growth plans.

Trek Metals has confirmed that Induced Polarisation (IP) surveying effectively targets concealed manganese mineralisation at its Kuro prospect, with visual manganese found in 43 of 51 recent drill holes. The company also identified a strong IP anomaly at the Coogan copper-gold prospect, planning four drill holes to test it.

Element 25 is pushing ahead with its Butcherbird manganese mine expansion in Western Australia and developing a first-of-its-kind US high-purity manganese sulphate facility, backed by major OEM partnerships and a US$166 million DOE grant.
