Quantum Graphite (ASX:QGL), The Company announces today the second and final phase of the thermal purification results of the test work program conducted by INEMET, ProTherm Systems and Sunlands Power.
This final phase of the program was supervised by the Company’s technical consultants and ALS’ Perth laboratories at Balcatta conducted the elemental analysis following thermal treatment at 2,850°C.
The results confirm within the sensitivity of the test equipment:-
- Uley flake purity of 99.99% graphitic carbon (gC) is achievable from the Sunlands proprietary thermal treatment process
- The direct correlation between predicted impurity element removal (IER) and actual removal of these elements based on the boiling point data for all detectable Uley flake impurities
Table 1: Graphite Purity after Thermal Treatment @ °C
These results have a significant impact on the Company’s Uley 2 Project, i.e.,
- Based on this purity level the current market price for the Company’s Uley 2 products is approximately US$1,5401 per tonne - compared to the basket price used in the 2019 DFS of US$9192
- The Sunlands proprietary process is commercially scalable and can deliver this level of purity in a production environment
- Commercial demand for such purified product confirms the need to increase production levels in the anticipated revision of the Company’s DFS
Commercial Impacts of Results
The results confirm that commercial production of Uley flake at a purity of 99.99% can be achieved utilising the Sunlands proprietary process, free of any chemical processes or processes with adverse environmental effects.
Managing Director, Sal Catalano commented that,
“The results deliver on the Company’s commercial strategy to deliver the leading natural flake products across all applications. From high technology industrial uses to thermal storage products and feed material for Li-ion anode, Uley flake demonstrably delivers a superior product in an environmentally sustainable way”.
As previously announced, the Company is updating its 2019 Definitive Feasibility Study (DFS). As part of this update the Company will revise the DFS basket price to reflect the market price for Uley flake at the 99.99% purity level. Based on the latest available market data, the market price across all Uley products at this purity level is approximately US$1,540 (DFS, US$919). The Company will revise the DFS basket price based on the relevant market price at the time of the release of the update to the DFS.
There is significant market demand, across industrial and battery markets segments, for such purified graphite. This strengthens the market case for the production level to be increased to more than 100,000 tonnes per year.
