VANCOUVER, BC, February 11, 2020 – Nicola Mining Inc. (the “Company”) is pleased to announce positive preliminary grade and copper recovery results on flotation tests conducted at ALS Metallurgy Kamloops laboratory (“ALS”) under program KM5954. The tests were designed to simulate copper and magnetite recovery into separate concentrates through flotation and magnetic separation.
A sample from the mine’s historic waste rock terraces underwent sorting via COM Tertiary XRT Sorter tests. The testing provided encouraging results and indicate that low-grade mineralized material from the historic mine waste terraces can be upgraded to a feed stream appropriate for copper flotation and magnetic separation. Sorted product from the XRT Sorter was used as feed in the flotation and magnetic separation tests. This material had feed grades of 0.34% copper (Cu) and 6.9% iron (Fe).
Key results of the tests include the following:
- A Copper concentrate of 29.6% Cu and 29.4% Fe, with 73.1 % recovery copper in un-optimized laboratory batch tests.
- Magnetite (Fe₃O₄) concentrate grading 64.8% Fe or (93.9% Fe₃O₄)
Sorted mill feed material was first ground to a nominal 132µmK80 and underwent an initial rougher separation to confirm copper recoveries. Rougher concentrate was reground to 21µm K80 prior to three stages of cleaning to produce a final copper concentrate. The copper rougher tailings were processed by using magnetic separation. The magnetic rougher concentrate was reground to 28µmK80 and cleaned via Davis Tube to produce a high-grade magnetic concentrate.
Initial material that contained 0.34% Cu and 6.87% Fe was separated into 2 key concentrates
- Cu cleaner concentrate containing 29.6% Cu and 29.4% Fe. Copper recover was 73.1%.
- Magnetite cleaner concentrate containing 64.8% Fe, which was comprised of 93.9% Fe₃O₄ and approximately 2.9% of the overall feed mass.
The ability to produce a copper concentrate grading 29.6% Cu with 73.1% Cu recovery rate in initial testing is very encouraging. Positive Cu grades were further augmented by the magnetite concentrate that contained 64.8% Fe or (93.9% Fe₃O₄) and accounting for approximately 2.9% of the overall mass. The Company plans to conduct further testing on the grades of the fines in
the historic waste rock terraces, which account for approximately 50% of the tested material and graded 0.25% Cu and additional lab testing to further optimize and confirm grades and recovery.
