Surge Copper Corp. (TSXV: SURG) has obtained positive results from its recently completed metallurgical testwork programme focused on the Seel deposit, located on the Ootsa Property in central British Columbia.
This testwork programme was designed to advance bulk copper-molybdenum concentrate flotation parameters, confirm molybdenum recovery performance into a separate molybdenum concentrate at marketable grades, and investigate further opportunities to increase precious metal recoveries from tailings streams within the flowsheet.
Surge engaged ALS Metallurgy Kamloops to complete the testwork programme which ran from February 2022 to October 2022.
- Large-scale flotation testwork programme utilising a set of four composites made up of 2,000 kilograms of sample material representative of different rock types, grades, and volumes within the deposit
- Excellent overall molybdenum recoveries from bulk circuit feed to molybdenum concentrates of 75 to 82 percent at molybdenum concentrate grades of 47 to 52 percent, including high separation recoveries relative to bulk concentrate feed of between 90 to 97 percent
- Confirmation of robust copper and precious metal recoveries in locked cycle tests across all composites using standardised parameters resulting in copper concentrates grading between 27 to 29 percent copper, with copper recoveries ranging from 83 to 90 percent, gold recoveries ranging from 47 to 60 percent, and silver recoveries ranging 41 to 68 percent
Confirmation of potential for additional leach recoveries of gold from tailings streams
“Overall, this testwork programme was quite successful in that it greatly improved our understanding around some key variables, and generally advanced our knowledge on metallurgical performance for this deposit, further preparing us for future advanced economic or engineering studies,” CEO, Leif Nilsson, said.
A standardized set of parameters was able to produce the desired metal recoveries and give the Surge team great confidence that the varying lithologies and grade ranges will perform in an operational scenario.”
The Seel deposit forms the largest overall component of the recently updated mineral resources at Ootsa. This testwork programme utilised a set of four composites comprised of approximately 2,000 kilograms of sample material derived from nine separate core holes drilled from the West Seel zone during the 2020-2021 exploration programme.
