Latest Metallurgical Testwork News

St George Mining’s initial beneficiation testwork at its Araxá Project in Brazil has delivered high-grade niobium concentrates and a promising rare earth concentrate, validating its dual commodity approach and underpinning next-stage pilot plant plans.

OzAurum Resources has delivered another round of strong near-surface gold intercepts at its Mulgabbie North Paleochannel Project, reinforcing a low-cost heap leach development pathway and progressing site construction.

Barton Gold has completed a 3,677m drilling program at its Tolmer Silver discovery, confirming high-grade silver mineralisation with assays exceeding 2,000 gram-metres and producing a concentrate grading over 100,000 g/t Ag without complex processing.

Meteoric Resources has reported exceptional pilot plant performance at its Caldeira Rare Earth Project in Brazil, achieving magnet rare earth oxide recoveries of 80% in May and exceeding pre-feasibility study targets.

Aurum Resources has unveiled a robust Pre-Feasibility Study for its Boundiali Gold Project in Côte d'Ivoire, declaring a maiden Probable Ore Reserve of 1.21 million ounces and targeting first gold production in early 2028.

Morella Corporation’s final 2026 drilling results at Mt Edon reinforce broad rubidium mineralisation and reveal multiple higher-grade zones, advancing the project toward its maiden JORC Mineral Resource Estimate.

Ark Mines has produced high-grade monazite and titanium dioxide products from its Sandy Mitchell heavy mineral concentrate, marking a key step toward commercialising its North Queensland rare earths project.

Magnum Mining’s initial 24 auger holes at Piracanjuba North all intersected near-surface rare earth mineralisation, showing promising grades and high desorption rates that suggest efficient extraction potential under mild conditions.

Pivotal Metals has unveiled high-grade copper, nickel, and platinum group metals intersections from its maiden drill program at the Belleterre Projects, confirming a significant mineralised system and advancing exploration across multiple targets.

Barton Gold has secured $25.9 million through an institutional placement, fully funding critical resource upgrades, feasibility studies, and drilling at its key South Australian gold and silver projects.

Prodigy Gold has won a $112,152 co-funding grant from the Northern Territory Government to drill a 600m hole at its Hyperion Gold Deposit, targeting a major untested geophysical anomaly that could expand the 454,000-ounce resource.

Elevate Uranium has boosted the Marenica Uranium Project's Mineral Resource by 31% to 52.8 million pounds of U3O8, building on a recent doubling of grade. Ongoing infill drilling and pilot plant processing underpin advancing feasibility studies.
