The company has completed three detailed metallurgical test work programs that demonstrate excellent recoveries via conventional flotation of all major rock types to generate clean, highly saleable concentrates.
Highlights from the test work include:
- Silver recoveries on average of 85-90%, lead recoveries of 85-90% and zinc recoveries of 83-87% from locked cycle tests.
- Test work completed on all major rock types, varying grade profiles and from different areas across the deposit.
- Higher recoveries were achieved at a coarse grind size of approximately 200 microns.
- Oxide-sulphide blend testwork established economic recoveries allowing for the co-processing of oxide and sulphide mineralization via flotation.
