This second phase of testing has found 36% of the refined product consists of higher-value large, jumbo and super-jumbo flake sizes.
Executive chairman George Frangeskides said this round of tests confirmed “two very important things” for the future economics of the project.
“Firstly, that a saleable, 97.3% product can be produced.
“And secondly, that in that refined product is included a significant proportion of the higher-value flake graphite that is sought-after for a range of industrial uses, which still underpin the majority of the demand for natural flake graphite globally.”
The AIM-listed company said it will now move on to the design of a further phase of refining testwork alongside an assessment of whether Amitsoq can turn out the sort of high-purity product that wanted by the battery metals sector.
“This completed work on one of our key assets provides us with great confidence as we move into 2020,” Frangeskides added.
