From Science Advances (In depth Article):McDermitt Caldera (Nevada/Oregon Border) was formed after a massive magma eruption approximately 16.4 million years ago, dredging up untold scores of lithium and other metals. A lake eventually inhabited the caldera, which deposited a layer of sediment spliced with the lithium that today is over 600 feet deep. The result: a clay called smectite.
But that was just the first lithium injection. Eventually, as volcanic activity heated up again, hot brine containing additional lithium was driven up into the existing smectite, infusing it with even more of it. Now, the clay was no longer just smectite, but a uniquely lithium-rich illite.
"They seem to have hit the sweet spot where the clays are preserved close to the surface, so they won't have to extract as much rock, yet it hasn't been weathered away yet," Borst told Chemistry World.
This is good news for miners. Not only is this particular illite more rich in the metal, it's supposedly easier to separate. Plus, the deposits are mostly concentrated in one spot at the southern tip of the pass, limiting the area impacted by mining.
At least in theory. The extraction of lithium can, depending on the methods used, emit vast amounts of CO2, contaminate groundwater with dangerous heavy metals, and guzzle tons of fossil fuels. Its environmental toll shouldn't be overlooked in the rush to green transportation infrastructure.
This back-of-the-envelope estimation is calculated using caldera-wide extrapolation of publicly available drill hole data from Lithium Americas Corp. and Jindalee Resources Ltd. and is not a reporting code-compliant mineral resource estimate that considers economic viability. Even if this estimation is high due to variations in sediment thickness and/or Li grade, the Li inventory contained in McDermitt caldera sediments would still be on par with, if not considerably larger than, the 10.2 MT of Li inventory estimated to be contained in brines beneath the Salar de Uyuni in Bolivia (12), previously considered the largest Li deposit on Earth.
"enhanced." LOL LOL LOL. I can't wait.Our local library card gives us full and free access to M* via a log on to the internet from anywhere, with no ads or any other issues to deal with. It is a great service I have used for years.

My local library provides free access to Morningstar Investment Research Center (MIRC).
MIRC includes M* articles and videos, fund analyst reports, Portfolio X-Ray,
newsletters (e.g., FundInvestor, ETFInvestor), and various tools.
Like you, I've also used this great service for years.
MIRC will be replaced with an"enhanced database experience coming in September."

That is correct--I have some cash in SNAXX which is paying a very nice interest rate, but MMs do not guarantee those rates for very long. I do not know how long I will be able to get CDs for 5.4%, but for a retired investor, that is a very attractive rate that I would be very comfortable and satisfied with that, especially when I can get a CD that pays monthly dividends. I am not recommending anyone do what I would do, but 5.4% CDs are very attractive to me for now, and that is where I would put the $100k if it was available to me now. Others can buy that Boat and I wish them well!!I'm guessing dtconroe wants to lock in 5.4% for 2 or more years. The Fido mm rate would drop significantly if the US enters recession in 2024 or 2025 .
