Lithium chemicals company undertakes rapid transformation

MINING | Lepidico

For Perth-based lithium chemical company Lepidico, the 2019 June-ending quarter has been a truly transformational period. In April, the firm announced that its pilot plant project for the production of lithium carbonate, using its patented L-MaxŽ technology, had commenced the commissioning phase. This milestone was followed by three significant announcements on May 7th: First, Lepidico confirmed an-all share offer to acquire lithium company Desert Lion Energy Corp, listed on the TSXV. Then it announced a Memorandum of Understanding (MoU) with Abu Dhabi-based chemical manufacturer Gulf Fluor. Finally, Lepidico launched a rights issue to raise up to AUS$10.8 million in new shares. Factor in the company’s earlier pivot towards lithium hydroxide production, utilising its new LOH-Max™ process, and it is clear to see that Lepidico has undergone a significant metamorphosis since the beginning of 2019. The successful commissioning of the pilot plant project in Western Australia, onschedule and within budget, delivered a big

MINING | Lepidico Lepidico began engineering work in June, with a planned four-month schedule for its consultant Lycopodium to complete the required circuit engineering and integrate it into the Phase 1 plant design. “We have set an aggressive but realistic timeline so we don’t impose too much of a delay on our planned development of the Phase 1 plant project,” says Walsh.

Therefore, the company’s ongoing evaluation of a plant development in Abu Dhabi, along with its incorporation of LOH-Max™ capabilities into the Phase 1 plant has meant that the final feasibility study for the plant is now due in the first half of 2020, at which point Lepidico will seek to finalise its offtake and financing agreements.
