Waratah Minerals (ASX:WTM) said initial geometallurgical test work from the Consols Zone at its Spur Project in New South Wales returned high gold recoveries of over 89%, ranging between 89% and 93%, by gravity and conventional leaching from samples with coarse, free-milling gold in grain sizes up to 601 micrometers, according to a Wednesday Australian bourse filing.
The company said conventional leaching recovery ranged between 68% and 86%, with negligible gold tied in silicates at 0.4%, with the results mirroring previous metallurgical test work from Spur and suggesting a simple, conventional process pathway.
