Castillo Copper’s (CCZ) metallurgical test work has confirmed a copper upgrade for the Big One Deposit within the NWQ Copper Project in Mt Isa, Queensland.
The company reported the results from initial preliminary metallurgical test work on samples from the Big One Deposit.
Castillo’s best results from the test work included copper with a 0.72 per cent head-grade to 7.2 per cent post-test work.
The company said the beneficiation potentially transformed several ore samples into a copper concentrate with confirmed upgrades ranging from five times to 10 times for copper metal.
As such, Castillo Copper’s Managing Director Dr Dennis Jensen said the company’s board is delighted with the results.
“Moreover, receiving these initial results now is timely as the board is now ramping up efforts to secure a processing agreement and clear path to market,” Dr Jensen said.
Further testing is now underway on samples from the Big One Deposit to determine the final optimal results.
The deposit has already been significantly de-risked, thanks to its current global inferred mineral resource estimate of 21,886 tonnes contained copper metal.
Moving forward, Castillo said it plans to undertake a third drilling campaign to extend the known mineralisation in the area, with a focus on a sizeable known bedrock conductor north of the line of lode.
Incremental geophysical surveys will also be undertaken to identify fresh targets.
