A Scoping study assessing the Governor Broome Project, completed by TZMI, was completed and announced in April 2024. This work highlighted the excellent potential of the project, which has a $139m NPV10, an IRR of 54% and a capital payback period of less than two years. The Company is actively investigating options for realising the value of the Governor Broome Project.
