Bulk Metallurgical Testwork – Strong Concentration Results

Bulk Metallurgical Testwork – Strong Concentration Results

The Thackaringa project is planning to mine ore from three surface deposits. The host rock (silica and feldspars) contains approximately 20% sulphides (mainly pyrite), with cobalt at 900–1000 ppm. Upgrading the ore to a sulphide concentrate is an important step to developing an economically viable project.

Release highlights:

  • Cobalt Blue has now completed gravity and flotation testwork on an 820 kg composite sample of Thackaringa ore.
  • Recovery of cobalt to the concentrate was 92%, and the mass recovery to concentrate was 17%. The cobalt recovery represents a strong result and a significant milestone in the development of the Thackaringa project.
  • Recovery of cobalt was achieved with coarse crush size of 1.2 mm and gravity separation, indicating low capital and operating costs compared to fine milling and floating the entire ore.
  • Cobalt Blue is pleased to announce the appointment of Dr Andrew Tong to manage COB’s Feasibility Studies. Dr Tong’s background is included in this release.
