Cobre Ltd. (ASX: $CBE) has achieved a significant milestone in its Ngami Copper Project (NCP) located in Botswana's Kalahari Copper Belt. Along with the discovery of very high-grade copper, the company also checked the box for In-Situ copper recovery. Cobre completed the initial phase of a program testing the feasibility of an In-Situ Copper Recovery (ISCR) process. This method offers an environmentally friendly and potentially cost-effective way to extract copper and silver from the mineral deposit. This test was a huge success for Cobre for two reasons: 1. Results say that the project has over 40 kilometers of drilled test copper-silver mineralisation with a consistent grade. The company has an exploration target exceeding 100 million tonnes at 0.5% copper. 2. The company is feasible for the In-situ process at the site. But why is the In-situ process so important and how Cobre is going to benefit from it? And most importantly before that, what is the In-Situ process?
