Lithium Brines and New Technology - the way to go.18 Jan 2021 20:24
"Preliminary Economic Assessment prepared by Advisian, a consulting arm of Worley Parsons, released June 18, 2019 considers the production of battery-quality lithium carbonate through a phased build-out to a total 20,900 tonnes per annum (tpa) from the contemplated joint venture with Lanxess AG at their three-operating bromine-processing plants.
Key Points:
Annual production: 20,900 tonnes lithium carbonate (1)
Plant operation: 25 years (2)
Total capital expenditures estimate of US$437 Million (3)
Non-optimised reagent cost per tonne lithium carbonate of US$3,107
All-in operating costs, including all direct and indirect costs, reagent, sustaining capital, insurance and mine-closure costs of US$4,319 per tonne of lithium carbonate (4)
Average selling price $13,550 USD per tonne battery quality lithium carbonate (5)
Pre-tax US$1.3 Billion NPV at 8% discount rate and IRR of 42%
Post-tax US$ 989 Million NPV an 8% discount rate and IRR of 36%
Resource upgraded to 3,140,000 tonnes Lithium Carbonate Equivalent (LCE) at the Indicated Category
Notes:
All model outputs are expressed on a 100% project ownership basis**
[1] Total production, using existing brine supply rates at the completion of Phase 3
[2] Plant operation commences upon completion of Phase 1
[3] Includes 25% contingency of both direct and indirect capital costs
[4] Includes all operating expenditures, including sustaining capital and allowance for mine closure
[5] Selling prices ranging between US$10,840-16,260/tonne were modeled as part of sensitivity analysis
** 70/30 JV in favor of Lanxess AG with an option for Standard Lithium to achieve 40% subject to attaining certain milestones"
