Cassini Resources Limited acquired the West Musgrave Project from BHP Billiton in 2014. Cassini paid BHP an initial deposit of A$250,000 for the project along with a 2% smelter royalty. An additional A$10 million would be paid to BHP after the mine has operated for one full year. Cassini released the results of a scoping study in early 2015. This considered two cases, the first a staged ramp-up from 1.5Mtpa to 4Mtpa in the eighth year of operation, and the second a 4Mtpa case. The first case is considered in the accompanying analysis. Full ownership of the project transferred to joint venture partner, OZ Minerals Ltd in October 2020.
