Cobre begins metallurgical testing at Ngami following more high-grade copper in pump test wells

11:01 03 Jul 2024 AEST

Cobre Ltd (ASX:CBE) has received the first round of laboratory assay results from hydrogeological test wells at the Comet and Interstellar prospects on the Ngami Copper Project (NCP) in the Kalahari Copper Belt (KCB) of Botswana.

The results from Comet, which registered up to 1.6% copper, revealed consistently higher-grade mineralisation than previously identified via portable x-ray fluorescence (pXRF) testing.

Cobre has also begun advanced metallurgical column leach test work on copper samples from the Comet and Interstellar targets, designed to estimate in-situ copper and silver recoveries which will offer more insight into the in-situ copper-silver extraction process.

Advancing toward in-situ copper recovery

“The recent assay results provide further encouragement that consistent higher grades of copper-silver mineralisation extend at depth at the Comet target,” Cobre CEO Adam Wooldridge said.

“The next stage of metallurgical test work combined with our hydrogeological injection tests will provide a foundation for progressing an in-situ copper recovery process at Ngami.

“We look forward to reporting test results as these become available over the next 4 months.”
