My 2 pence...
My father has been involved in Lithium industry for over 30 years in senior roles with one of the lithium major company Lithco/FMC/now Livent and owns the largest proven lithium resource (joke!) in the UK - a lump of spodumene outside his caravan in N.Wales originally from Lithco’s ( now closed) Cherryville mine in North Carolina.
Lithium demand is generally measured in LCE’s (lithium carbonate equivalents) and in 2020 is expected to be around 300k mt/yr increasing to 1000k mt by 2025 based on electric vehicle sales. This growth and further growth past 2025 will make previously uneconomic resources viable, but not necessarily all of them. Cornish Lithium, despite press reports, has low quality resources from a global view and no proven technology to economically extract Lithium and then convert to a ‘battery quality’ lithium carbonate or hydroxide ( nice graphics do not prove anything). Invest in them with caution.
Most lithium today and in the future will come from brines in S.America and open cast spodumene mines in Australia, with others elsewhere under development. The only potential deep mine is in Zadar, Serbia where Rio Tinto have found new mineral zadarite which they hope will allow them to extract both borax and lithium but this is years (and multi million $ ) away.
Despite the almost daily announcements of new EV launches there is very little investment in developing new Lithium resources and as every EV needs lithium in it’s battery, then very soon battery demand will exceed lithium supply.
Ironing 2 miles deep into a system? you obviously dont understand.
