Sedimentary lithium deposits

Sedimentary rock deposits account for about 8 percent of known global lithium resources, and are found in clay deposits and lacustrine evaporites.

Clay deposits — In clay deposits, lithium is found in the mineral smectite. The most common type of smectite is hectorite, which is rich in both magnesium and lithium. It gets its name from a deposit containing 0.7 percent lithium found in Hector, California.

Many companies are in the research and development phases for their clay deposits, but no companies currently produce lithium from them.

Lacustrine evaporites — The most commonly known form of lithium-containing lacustrine deposit is found in the Jadar Valley in Serbia, for which the lithium- and boron-bearing element jadarite is named.

The Jadar deposit, owned by Rio Tinto (NYSE:RIO,LSE:RIO,ASX:RIO), reportedly contains more than 200 million tonnes of lithium. The company claims it is one of the largest lithium deposits worldwide.

Rio Tinto signed a memorandum of understanding with the government of Serbia to fast track the development of the deposit. The project is currently in the prefeasibility stage and could begin construction in 2023 following a final investment decision from Rio Tinto.
