Rumble Resources Limited announced the metallurgical results from the initial sighter program focused on the transition/fresh sulphide ores selected from the Chinook and Tonka Prospects at the Earaheedy Project, located 110km northeast of Wiluna, Western Australia. Highlights: Outstanding initial flotation test work results from zinc sulphide dominant ores across
the Earaheedy Project has resulted in: High zinc recoveries to 90% Zn in cleaner concentrates;
Coarse primary grind size of 150 micron; Fast flotation kinetics with clean sulphide separation using site water; Simple and conventional processing flowsheet recovers a bulk zinc
concentrate with metal credits utilising an uncomplicated and lower dosage reagent scheme;
Zinc concentrate grades to 59% Zn, with no significant deleterious elements, supporting a very marketable product. Initial metallurgical results backed by fast kinetics at coarse grind sizes support a
potential simple low Capex and Opex flowsheet for the Earaheedy Zn-Pb Project; Recoveries and concentrate grades are at the higher end of global benchmarks
when compared to current zinc developer /producers; Considerable potential for additional improvements through metallurgical
optimisation test work and value add beneficiation studies planned for 2023; and JORC Mineral Resource Estimate to be brought forward to the first half of 2023.
