Latest Sx Ew News

Cobre has secured 150,000 tonnes of low-cost ENAMI oxide material while testing two ways to recover copper from Sierra Atacama’s old leach infrastructure. The initiatives could lift SX-EW utilisation, although the historical pad opportunity remains early-stage and non-JORC.

Cobre has outlined a three-stage plan to lift Sierra Atacama’s copper cathode capacity from its existing configuration to 18,000 tonnes per annum, then 25,000 tonnes, with a larger 50,000-tonne case under consideration. The targets depend on refurbishment, permitting, further drilling and resource modelling.

Cyprium Metals says its long-delayed Nifty Copper Complex is entering the final commissioning phase, with first copper cathode production expected in the December quarter of 2026. The restart is backed by A$121 million in equity raisings, a refinanced US$27.3 million loan facility and A$68.5 million in cash at year-end.

Revolver Resources has taken its Dianne Copper Mine Project from study towards construction readiness, with a larger resource, secured approvals and a forecast $125.7 million pre-tax cash flow. But the restart still depends on project-level funding before a Final Investment Decision can be made.

AIC Mines is paying $120 million for the Mt Cuthbert copper project in northwest Queensland, funded partly by a $70 million placement to Hawke’s Point. The deal would add 246,000 tonnes of contained copper to the group’s resources, but comes before Mt Cuthbert has a single Ore Reserve.

Cyprium Metals has begun acid commissioning at its Nifty heap leach pads for the first time since 2009, bringing its copper restart into the operational phase. The company now expects first cathode production in the fourth quarter of 2026, subject to energisation, wet commissioning and ramp-up.

Cobre has secured two ore supply agreements that could add about 300 tonnes of copper cathode a month from Q4 2026, without changing its existing production guidance. The deal is designed to lift utilisation of the under-used Sierra Atacama plant while the company transitions from underground to open-pit mining in 2027.

Freehill Mining navigates severe weather disruptions in Chile's Coquimbo region with steady aggregates sales and advances copper expansion plans, leveraging legislative changes to boost production capacity.

Freehill Mining has appointed seasoned engineer Marco Meneses to spearhead development at its Blanco y Negro copper-gold project, coinciding with Chile's planned legislative change to double processing thresholds for small miners, enhancing project viability.

Austral Resources has identified a second parallel copper-gold lode at its Cameron River Project, with drillhole 26SQRC006 hitting significant grades. The discovery supports the company’s strategy of regional growth around its Rocklands Processing Facility.

Revolver Resources has completed critical design and infrastructure upgrades at its Dianne Copper Mine Project, edging closer to a Final Investment Decision and first copper production within a year.

Cobre Limited is progressing a major upgrade of its Sierra Atacama copper project in Chile, aiming to convert a large foreign resource estimate into a JORC-compliant Mineral Resource Estimate while launching a 40,000-metre drilling program targeting near-mine expansion and deeper sulphide mineralisation.
