The tests demonstrated high recoveries, with 97.3-97.6% for zinc and 99.4% for lead, indicating a strong separation of mineralized material. These results suggest that Dense Media Separation \(DMS\) could significantly reduce overall processing costs by pre-concentrating ore prior to flotation. Reasoning: The document reports successful initial bench-scale metallurgical test results for zinc and lead from the Scotia Mine, showing high recoveries and potential for significant cost reduction through pre-concentration. This is a positive development for the project's economics, though it is still at an early test stage. - Positive factor: High recoveries for both zinc and lead achieved through HLS test work, indicating strong separation of mineralized material. - Positive factor: The test work suggests potential for significant reduction in overall processing costs at the Scotia Mine by pre-concentrating high-grade material. - Positive factor: Successful bench-scale HLS tests simulate full-scale DMS, a proven and cost-efficient method. - Negative factor: The test work is currently at bench-scale \(HLS\), and full-scale DMS plant performance may vary. - Negative factor: The results are from initial tests on high-grade composite samples, and variability across the deposit is not fully addressed in this release. Low confidence — this extraction should be reviewed alongside the original source.
