Following a definitive feasibility study in November 2018, the company has continued with bulk metallurgical variability testing as it seeks to further de-risk the project.
These tests are focusing on dense media separation and spiral treatment of ore samples taken from the upper and main pegmatite zones within the proposed pit at Arcadia.
Prospect managing director Sam Hosack said the test work results demonstrated the quality of the project and the company’s ability to de-risk and optimise it prior to development.
High-quality delivery as project goes into development
“The investment we have made into technical validation and value engineering for project supports our ability to successfully deliver on the Arcadia Lithium Project.
“The company has attracted market-leading professionals to join the team, including individuals with extensive experience in DMS, gravity and flotation processing of lithium-bearing minerals.
“With these initiatives being undertaken by leading independent specialist organisations, we are delivering on a high level of quality for each initiative and de-risking the project as we go into development.”
Premium low petalite delivery
The test work was undertaken at an independent third-party facility in order to provide impartiality and ensure quality control, which confirmed the amenability of Arcadia ore to deliver premium low iron petalite concentrate product containing plus 4% lithium oxide and plus 1% iron oxide.
A follow-up bulk test work program to optimise petalite recovery by gravity separation has begun with an expanded spodumene flotation program underway.
