Massive deposit of lithium found in Wyoming could meet all U.S. demand
This article (and the UW press release they quote) state that the estimated 228,000 tons of lithium present at the site is "enough to meet annual U.S. demand". I'm not sure what this last statement means since it isn't qualified by "for XXX years assuming no increase in consumption".According to the USGS[1], US consumption for 2011 was estimated at ~2000 tons. So, this source is, indeed, significant. According to the article, it is also twice as large as the other known US source (in Nevada), so combined, the US has ~150 years worth of domestic Li at its current consumption rates.[1] https://minerals.usgs.gov/minerals/pubs/commodity/lithium/mc...
