The results were from phase two of Cardinal’s metallurgical test program.
Cardinal's flagship project is the Namdini deposit, which is host to a 4 million ounce gold resource that is open at depth and along strike.
The phase two metallurgical test program is focused on determining resource variability of the main lithology domains being metavolcanics, granite and diorite.
The test program was developed to enhance Cardinal’s metallurgical understanding in order to help ensure a robust process design.
The test results thus far are demonstrating good lithological consistency, which will allow for predictable metallurgical performance in a production scenario.
Importantly, a conventional grind‐flotation‐regrind carbon-in-leach flowsheet continues to be the preferred process option.
As the metallurgical testing advances in the project development phase, the process flowsheet will continue to be optimised in order to provide the necessary detailed design criteria.
The results of a scoping study and preliminary economic assessment are due late in the third-quarter.
