The feasibility study will comprise inputs of other consultants for certain aspects, including an update of the pit designs, tailings handling systems and bulk water and power supply.

It will also develop an engineered construction and operating plan with considerations for social, environmental and water management, additional permitting, geotechnical engineering, metallurgical testing, process design and mine planning.

Forsys Metals also appointed SGS South Africa to carry out additional metallurgical studies, including pilot plant testwork.

Forsys CEO Marcel Hilmer said: "The commencement of the feasibility study is the next important milestone in the development of the Norasa project."

"The FS will consolidate all accumulated project mine and technical data."
