Latest Metallurgical Recovery News

American Tungsten & Antimony has produced antimony ingot from Arizona-mined material at its Nevada refinery, providing the first physical demonstration of its proposed US mine-to-metal chain. The milestone creates samples for testing and customer qualification, but the underlying asset acquisition remains incomplete and product quality is yet to be disclosed.

Carnavale Resources is approaching the final stretch of its bankable feasibility study for the 80%-owned Kookynie Gold Project, backed by a 120,000-ounce resource and strong metallurgical recoveries. The project still requires financing, a toll-treatment agreement and final economic modelling before it can move from promising study to mine development.

Western Gold Resources has sharply expanded the proposed Gold Duke mine, lifting its production target by 62% and forecasting A$72.9 million in operating surplus. The preliminary study is stronger on paper, but still depends on funding and the restart of toll treatment at Wiluna.

True North Copper has lifted the contained copper inventory across its Cloncurry Copper Project by approximately 18% through a larger Mongoose-Taipan resource. The update gives the late-2026 pre-feasibility study a bigger technical base, but it remains a mineral resource rather than an economic reserve.

Sinclair Gold has doubled the JORC Mineral Resource at its Mt Henry project to 1.8 million ounces after just 20,426 metres of drilling. The shallow resource remains open, with five rigs operating and assays pending from 25 holes outside the current estimate.

Catalyst Metals has increased the Trident underground Ore Reserve by 32% to 524,000 ounces, supporting a planned mine life of more than 10 years. The result strengthens the company’s ambition to build a 2Moz Reserve base across the Plutonic Belt, although further growth depends on drilling and mine execution.

Maritana Minerals has increased the Burbanks Gold Project’s Mineral Resource by 62% to 755,000 ounces, pushing group resources above 2 million ounces. The growth is concentrated at Burbanks North, but the inventory remains predominantly Inferred and has yet to support an Ore Reserve.

Kingsgate Consolidated has increased Nueva Esperanza’s Ore Reserves by 31% for silver and 37% for gold, extending the assumed reserve life beyond 12 years. The gains are largely driven by higher price assumptions and lower royalties rather than new drilling.

First Au Limited has secured a potential processing pathway for its Gimlet Gold Project through a conditional 24-month ore purchase agreement with Forrestania Resources. The arrangement could reduce the need for a standalone processing plant, but it remains dependent on permits, a board decision to mine, technical acceptance and commercial viability.

DPM Metals has extended mineralization beyond the existing Dumitru Potok resource in Serbia, led by a 21-metre interval grading 5.44% copper equivalent. The company will add up to 15,000 metres to its 2026 drilling campaign as it works towards a resource update and preliminary economic assessment.

Forrestania Resources has secured a framework to purchase and process up to 2 million tonnes of third-party ore while locking in key laboratory, haulage and reagent arrangements for its Lake Johnston and Edna May hubs. The agreements strengthen restart preparation, although financial terms, margins and delivery timing remain undisclosed.

Rox Resources has increased Youanmi’s Ore Reserve by 8% to 727,000 ounces after mining depletion, while the broader Mineral Resource edged up to 2.195 million ounces. The update excludes results from recent surface and underground drilling programs, leaving future revisions as a potential source of change.
