Hawkstone Mining Limited announced that results from ongoing metallurgical test work have demonstrated positive results with initial lithium recoveries in the 90% range, and successful removal of iron (Fe), aluminium (Al) and magnesium (Mg), with minimal losses of recovered lithium (Li) values, from leach solution produced from the mineralised material. Current test work is focused on the removal of calcium (Ca) and sodium (Na) from the leach solution which will result in the purification and concentration of the lithium sulphate (Li2SO4) enabling final processing to produce "battery grade" lithium carbonate (Li2CO3). Preliminary engineering studies have been completed by the Company's Phoenix-based engineer to determine process scenarios, possible mining, processing and consumable/product logistics scenarios, in addition to establishing contacts within the local, State and Federal governments. A broad level of support, including tangible economic incentives, has been demonstrated. Baseline environmental and cultural surveys forming part of the Plan of Exploration (POE) process were completed in 2020, and the Company is awaiting approval by the BLM to enable drilling to extend the known resource to the north and south. Approval for a bulk sample to allow larger-scale pilot plant testing in 2021 is also pending. The final reports on cultural and biological surveys were submitted to the BLM in late 2020 as part of the Programme of Exploration (POE) process. A draft POE has been circulated within the BLM and finalisation is expected during the current quarter allowing further drilling to commence at Big Sandy. Discussions with drill contractors indicate availability from early March 2021.
