Osisko Metals has announced the results of pre-concentrating test work on samples from the Pine Point zinc project in Canada.
Osisko Metals (TSXV:OM,OTCQX:OMZNF) has announced the results of pre-concentrating test work on samples from the Pine Point zinc project in Canada’s Northwest Territories.
As stated in the press release:
Conventional flotation test work is also ongoing on the material sorter pre-concentrates to validate and compare with recoveries from the historical Cominco Ltd. operations.
The purpose of the pre-concentrating test work is to evaluate potential, near-pit cost saving measures related to transportation and processing of mineralized material to a projected mill.
Highlights from the press release are as follows:
For X-Ray Transmission Material Sorting (“XRT”):
Zinc recoveries ranged from 76.5 percent to 98.0 percent (average of 92.6 percent)
Lead recoveries ranged from 94.9 percent to 99.7 percent (average of 97.8 percent)
Mass pull ranged from 34.4 percent to 73.5 percent (average of 49.1 percent)
Average grade of rejected material is 0.75 percent zinc and 0.047 percent lead
For Dense Media Separation (“DMS”):
Zinc recoveries ranged from 76.7 percent to 96.2 percent (average of 92.4 percent)
Lead recoveries ranged from 87.4 percent to 98.7 percent (average of 95.3 percent)
Mass pull ranged from 12.8 percent to 61.5 percent (average of 30.4 percent)
Average grade of rejected material is 0.75 percent zinc and 0.08 percent lead
Jeff Hussey, Osisko Metals President and CEO, commented:
“This round of test work expands upon previous material sorting studies and conclusively confirms Pine Point material is amenable to XRT pre-concentration. Indications are that roughly half of the waste rock material can be 2 rejected near potential pit operations with less than 10 percent loss of both zinc and lead mineralization. The benefits of incorporating a pre-concentration process at Pine Point would be to significantly reduce haulage costs and reduce the material throughput in the mill. Based on the combination of these benefits, project economics would improve from substantial operating and capital cost savings.”
