> So that means if you have a mine, you can't just mine do minimal refinement and then throw it on to the international standardized metals market the way it works for other materials. You need to build a highly sophisticated chemical processing facility that can handle your material specifically and produce high quality materials in a sufficient quantity that car makers can go threw the many rounds of testing that are required before a new source material ever makes it into a car. Grain of salt, but Jindalee claims 97-98% extraction rate on acid leeching cores at the McDermitt site on the northern caldera, on an inferred 21.5 million tons of lithium carbonate equivalent. They're expecting 1400 ppm on 3 Bt. Cores from Lithium Americas's inferred 19 Mt LCE find at Thacker Pass on the southern caldera is extracting at 84% on acid leeching. (For context, Clayton Valley's brine project converts at 85%.) Jindalee also claims they can also extract lithium phosphate from it and convert it to either carbonate or hydroxide. That's cool, but they don't really go into the cost of doing that, but I think the point is that it's supposedly a very flexible lode. > Since the lithium industry is comparatively so small the necessary expertise to do these things is not at all common. A few companies can do it and that's not very many people. So getting a team together that can pull of a major project like that isn't easy. GM and POSCO (the Korean cathode active material supplier for GM) are already working with Jindalee on feasibility of exploiting clay at scale, and GM already bought $650M of equity in Lithium Americas back in January for Thacker Pass. Probably know by February/March 2024 what the damage will be for processing clay, but Jindalee already expects to know whether they'll be shovels-in-ground by June 2024. That is a very fast turnaround for something that hasn't really been done before at any scale, much less 30 Mt of LCE-scale. Which I think is also why this article is a bit more focused on whether they can learn enough from how this find came about to make more finds like it. They might not know how to extract clay for a while, but if they can learn how to find more similarly exploitable clay first, they can get more investment to catch up. Inferring >30 Mt of LCE at 1400 ppm from just two sites in one caldera still seems like plenty of reason to fund figuring that out ASAP, though. Clayton Valley is like 6 Mt LCE; at this stage of the process, they were suggesting 1.3 Mt LCE at 900 ppm, on a feasibility target of 400 ppm. That was good enough for $700M in funding.
