NorthWest Copper (NWST) yields positive metallurgical results at its Stardust Project in B.C. recovering 98.6 per cent copper and 93.9 per cent gold.
Copper recoveries ranged from 94.2 to 98.6 per cent while gold recoveries ranged from 93 to 93.9 per cent.
The tests produced copper in concentrate grades from 21.8 to 26.2 per cent.
The company tested low, medium and high-grade composites.
High-grade composite testing included gravity, flotation optimization, and rougher kinetics and grind size compared to batch cleaner tests.
Low and medium-grade composite tests used a primary grind size of 150 microns with a 40 to 50 micron regrind, gravity and flotation.
Test work shows copper recovery had limited sensitivity to grind sizes between 75 and 150 microns.
Gold showed much higher recoveries at 75 microns vs. 100 or 150 microns.
Gravity recovered between 24 per cent and 42 per cent of the gold in the three tests.
Peter Bell, President and CEO of NorthWest Copper, stated,
“These exciting positive results support the advancement of our combined Stardust and Kwanika project. High grades, strong recoveries and a simple flowsheet provide a foundation for the combination. We are finalizing an initial Stardust resource in the next several weeks which will help underpin our unique high-grade copper-gold project.”
NorthWest Copper is a diversified copper-gold explorer and developer with a pipeline of projects in British Columbia.
NorthWest Copper (NWST) is trading flat at C$0.75 per share as of 11:28 am ET.
