The Sally Malay prospect, located just west of the Great Northern Highway, was originally owned by Normandy Mining until sold to the Mitchell River Group in 2000, a private company.

[3] The Mitchell River Group subsequently formed a publicly-listed company, Sally Malay Mining Limited, to develop the project.

[4] Construction commenced in September 2003, with mining scheduled to begin in January 2004 and commissioning of the process plant in the following August.

[8] By 2017–18, with nickel prices recovering, the company started planning for the reopening of the Savannah mine, signing new delivery contracts.

[14] The mine briefly reopened in 2019,[15] but was closed once more in April 2020 because of travel restrictions in the Kimberley region in place because of the COVID-19 pandemic and associated cost and supply issues.

[21] In 2021, Panoramic Resources had signed a new five-year delivery contract, now with Singaporean-based French company Trafigura, with shipments commencing in March 2023.
