About this update from Bradda Head Lithium Limited
[{"type":"text","content":"\n \n \n \n RNS Number : 9163O\n Bradda Head Lithium Ltd\n 13 October 2021\n \n \n \n 13 October 2021\n Bradda Head Lithium Ltd.\n (\"Bradda Head\", \"Bradda\", or the \"Company\")\n Metallurgical Test Work Underway with SGS Laboratories Canada\n \n Bradda Head Lithium Ltd (AIM: BHL), the North America-focused lithium development group, is pleased to announce that its planned initial and preliminary metallurgical testwork programme has commenced with SGS Canada (\"SGS\") on samples from its 100%-owned Burro Creek East lithium deposit. Burro Creek East already has a JORC-compliant resource identified and further drilling to add to this resource is already underway.\n \n Highlights:\n \n · Bradda Head Lithium has commenced a metallurgical test work programme with the highly-regarded SGS Laboratory in Canada. This programme will build on existing metallurgical work from its 2016 to 2018 programmes and utilise recent developments in lithium clay processing technology.\n \n · \n The Company's primary aim is to develop a suitable process flowsheet, whereby the target processing cost of Li extraction is less than US$4,000/t LCE (Lithium Carbonate Equivalent). The Company views this level as a suitable goal, noting that current lithium forecasts are pricing the long-term lithium carbonate market at upwards of US$12,000/t, and current spot prices are close to US$25,000/t.\n \n \n · The programme will also focus on identifying an appropriate path to produce a low-carbon footprint battery-grade lithium product.\n \n · Previous metallurgical test work conducted in 2016 to 2018 by J.E. Litz and Hazen Research proved that it was possible to extract 78% to 91% of the contained Lithium from Burro Creek East clays, using acid-leach technology, into an intermediate product. An 80% recovery was identified using an alternative roasting technology.\n \n · The early test work was undertaken assuming smectite-type clay mineralogy. However, the initial results of the Company's 2021 drill programme at Burro Creek East indicate that the dominant clay minerology is likely zinnwaldite or possibly tainiolite (pending detailed petrology and Scanning Electron Microscopy (SEM)), which may have a significant beneficial variation in the composition of gangue materials in the lithium clay.\n \n · Bradda has over 47km2 of sedimentary claims (with...
