The quantity of the metal discovered is estimated to be roughly equivalent to 382 million electric vehicle batteries.
The Salton Sea in the lower Colorado Desert in Southern California is scarcely filled with water and whatever is left is extremely salty. After researchers found out about an enormous reserve of 'white gold' resting beneath the lake’s southern end, a 2023 study revealed something remarkable. Sure enough, an enormous reserve of 'white gold' exists, but it was never expected that it would be worth $540 billion, reported the Daily Mail.
The giant landlocked lake, which is the largest in California, was studied by researchers at Lawrence Berkeley National Laboratory. They reported that in the deep hot underground pool is a treasure trove of lithium. IFL Science explains that the metal earned its nickname, 'white gold,' from the pivotal role it could play in the green revolution, providing raw materials to replace fossil fuel systems with batteries.
“It’s going to be roughly the equivalent of 382 million electric vehicle batteries,” Alex Prisjatschew, an engineer with the U.S. Department of Energy, told the Los Angeles Times. According to the report, this estimate is roughly 18 million metric tons of lithium. To conduct the study, according to The Hill, analysts from the University of California, Berkeley measured lithium concentrations in the lake’s rocks and designed computer models to estimate its potential production over the next 30 years. They also brainstormed various methods to extract the metal to the surface.
Even though the giant lake sits atop a whole treasure trove of lithium, its reputation is not all pristine, as its waters are considered harmful and toxic for humans. According to IFL Science, it is one of the most heavily polluted lakes. The reason lies in its history.
The desert lake was first created by accident in the 20th century when irrigation canals from the Colorado River flooded and spilled over into a basin. With the irrigation canal waters departing from the location, the lake began to shrink and soon converted to a slime of salty toxic dust. As winds gush atop the drying lakebed, they pick up enormous quantities of this toxic dust and blow it into the area where Imperial Valley residents breathe.
Still, the news of the metal treasure didn’t stop billionaires from investing their money in the project. Yet none was able to extract it sooner. One reason was the highly salty underground, which could instantly corrode their expensive equipment.
Plus, according to SFGate, arriving at the hotbed of lithium will not be easy and will require "geothermal production wells to extract the lithium-rich brine from thousands of feet below the earth’s surface, and once the lithium is dissolved from the brine, the liquid is pumped back underground." Besides this, thousands of residents who live around the lake will have to bear the consequences of drilling. Since drilling requires massive amounts of water supply, the residents will have to suffer the lack of water.
