The BoD published the recovery rate for the mini-plant during the testwork program in the Ann of 2018-03-01. In that program:

Hydrometallurgical batch tests have been completed on a secondary float (“tailings”) sample sourced from the Mt Cattlin Dense Media Separation plant. A tailings sample was provided for the testwork, which graded 2.7% Li₂O. From this a flotation concentrate was produced grading over 4.0% Li2O. Lithium recovery to concentrate was 96.6%.
The sample was then subjected to leaching under standard L-Max® conditions, with extractions for lithium of approximately 94%. Higher extractions are expected by undertaking an optimisation program to achieve rates similar those achieved in tests conducted on other lithium mica samples which realised over 98% extraction.
The leach liquor from the test was subjected to the usual L-Max® downstream process flowsheet in a series of batch tests. Lithium losses in the post leach L-Max® process were estimated at 4%, with total recovery from flotation concentrate to final product of over 90%.Battery grade lithium carbonate grading 99.8% was produced from these tests.

One should expect a similar analysis from the PP first campaign.
