Ann: Mineral Resource Estimate For Sinclair Caesium Zone, page-3

METALLURGY

Strategic Metallurgy Pty Ltd has been engaged to conduct a series of tests to determine an optimal
processing route, along with capital and operating cost estimates for the selected processing route.
Material for the initial metallurgical testing is a 25kg composite sample from the RC and Diamond
Drilling completed in 2016.
The metallurgical tests on the pollucite sample have readily resulted in the production of a very high
density, clear fluid that is expected to be confirmed through chemical analysis as caesium formate
brine. The second round, testing the leaching characteristics of varying size fractions, has commenced.

The Company is also advancing negotiations with parties interested in securing pollucite or caesium
product offtake.
