Cyprium Metals’ Cue project looks more promising after surface sampling returned high-grade copper
Latest surface sampling at Cyprium Metals’ Cue project revealed up to 13% copper at the Mt Eeyla target.
Cyprium Metals (ASX: CYM) has recovered high grade copper during a surface sampling program across its Cue copper project in Western Australia.
A review and field inspection were undertaken to firm up targets for the next phase of drilling.
Surface samples taken from Rapier West uncovered up to 12.3%, while several high grade samples were returned from Mt Eeyla including 13% copper, 10.6% copper and 10.2% copper.
At Mt Eeyla, Cyprium mapped eight gossan outcrops with four identified to contain “significant mineralisation”.
“We are pleased to report these high-grade copper samples as part of our regional review programs to increase the copper resource base at the Cue copper project,” Cyprium executive director Barry Cahill said.
“We look forward to updating the market with assay results as they become available as we continue to progress the Cue copper project,” Mr Cahill added.
Cue copper project
Cyprium completed its 80% acquisition of Cue during the March quarter after agreeing to acquire the project mid last year.
By the end of March, almost 12,900m of reverse circulation drilling had been completed at the project as well as 663m of diamond drilling.
A maiden JORC compliant resource is underway for the Hollandaire prospect, which hosts a historical estimate of 1.9 million tonnes at 2% copper.
Drilling at Hollandaire has returned numerous mineralised intersects such as: 9.3m at 15.4% copper, 2 grams per tonne gold and 29g/t silver from 61m; 10.4m at 14.9% copper, from 84.5m, including 4.5m at 21.9% copper with 1.2g/t gold and 46.4g/t silver; and 18m at 2% copper, including 3m at 6.1% copper, 2.61g/t gold and 16.25g/t silver.
As well as drilling, Cyprium has conducted metallurgical testwork using its unique methodology on Hollandaire massive sulphide ore with leaching resulting in copper extraction of 91.9% in 34 days, 91.7% in 21 days, and 75.4% in six days.
The testwork is part of a scoping study, which is underway and due for completion in the next 12 months.
