Vendetta Mining Corp (CVE:VTT) (OTCMKTS:VDTAF) reported “highly encouraging” results from material sorting test work at its Pegmont lead-zinc project in Queensland, Australia.
The X-ray transmission (XRT) sorter can easily differentiate between high-grade material and lower density waste at Pegmont, the company said in a statement Monday.
The results could indicate that plant feed material can be screened prior to grinding and flotation, removing waste and lower-grade material from the ore.

XRT ore sorting successfully removed external dilution from samples used in testing and removed internal diluting material from within the higher-grade intervals, Vancouver-based Vendetta told shareholders.
"At Pegmont the XRT sorter can clearly differentiate between high density/high grade feed from lower density waste material, (and) we are excited by the prospects of advancing to pilot scale test work and applying this commercially available technology to the next mining study,” said Vendetta CEO Michael Williams.
Peter Voulgaris, Vendetta’s project manager, told shareholders that the mass pull achieved in practice depends on the actual mined dilution that reports to the crusher and the amount of fines that are screened off prior to the material sorters, which will be resolved during the pilot-scale testing.
“We are particularly excited about the prospects of the XRF sorting to enhance transition metallurgical performance where density contrasts are more pronounced than in the sulphide material,” Voulgaris said.
Vendetta's 100%-owned Pegmont project is situated in the Mount Isa - McArthur area of Australia, which hosts one of the world's richest endowments of lead-zinc-silver mineralization, including several significant lead-zinc-silver mines.
