Located in the [[Lithium Triangle]], the Salar contains a large amount of [[sodium]], [[potassium]], [[lithium]] and [[magnesium]] (all in the chloride forms of [[Sodium chloride|NaCl]], [[Potassium chloride|KCl]], [[Lithium chloride|LiCl]] and [[Magnesium chloride|MgCl<sub>2</sub>]], respectively), as well as [[borax]].<ref name=trav1/> WithAs of 2024, with an estimated 9,000,00023 mln.&nbsp;[[tonne|t]], Bolivia holds about 722% of the world's known lithium resources (105 mln. tons); most of those are in the Salar de Uyuni.<ref>{{cite news |url=httphttps://mineralspubs.usgs.gov/mineralsperiodicals/pubs/commoditymcs2024/mcs2024-lithium/mcs-2011-lithi.pdf

Lithium is concentrated in the brine under the salt crust at a relatively high concentration of about 0.3%. It is also present in the top layers of the porous [[halite]] body lying under the brine; however, the liquid brine is easier to extract, by boring into the crust and pumping out the brine.{{citation needed|date=June 2020}} The brine distribution has been monitored by the [[Landsat program|Landsat]] satellite and confirmed in ground drilling tests. Following those findings, an American-based international corporation has invested $137&nbsp;million to developing lithium extraction.<ref>{{cite book |url=https://books.google.com/books?id=j0QrAAAAYAAJ&pg=PA60 |page=60 |title=Science and technology for development: prospects entering the twenty-first century : a symposium in commemoration of the twenty-fifth anniversary of the U.S. Agency for International Development |publisher=National Academies |year=1988 |author=National Research Council (U.S.).
