Cobre Limited (ASX: $CBE) has released results from ongoing hydrogeological test work on the Ngami Copper Project (NCP) in the Kalahari Copper Belt (KCB), Botswana. The tests demonstrate the ideal conditions for in-situ copper recovery (ISCR) and highlight the potential for further high-grade mineralisation. The hydrogeological programme has provided essential information to demonstrate the viability of the ISCR process for extraction of copper-silver from the significant strike of mineralisation.
The injection tests completed to date have provided an ideal result, demonstrating that the hydrogeological setting works well for an in-situ recovery process. This gives us the confidence to continue with engineering scoping studies and advanced metallurgical test work ahead of resource drilling.
Cobre's hydrogeological test results at the Ngami Copper Project in Botswana have shown promising potential for in-situ copper recovery. The successful injection tests and copper intersection indicate the suitability of the aquifer for ISCR operations and the continuity of high-grade mineralisation. The company is now progressing with engineering scoping studies and advanced metallurgical test work, aiming to develop a numerical model to simulate the aquifer's response to a scaled-up ISCR operation. With over 500,000 tons of contained copper in the target, the proof of the method presents a game changer for the district. Cobre aims to prove up a similar ISCR process to Taseko Mines Ltd's Florence Copper Deposit in Arizona, which shares a similar scale to NCP. The company's ambitions include further exploration and development of the ISCR process, with the potential for extensive in-situ copper mining in Botswana.
