Millions of gallons of water <strong>flooded a desert sink 228 feet below sea level<\/strong>.<\/p>\n<p>That&#8217;s how California&#8217;s largest lake, the Salton Sea, came to be.<\/p>\n<p>In the 1950s,<strong> the area was a booming resort town<\/strong> with celebs like Frank Sinatra and the Beach Boys hanging out in the water.<\/p>\n<p>Those days are long over.&nbsp;<\/p>\n<p>Shifting politics around water and rising temperatures have<strong> evaporated a third of the lake<\/strong>. The water is now twice as salty as the Pacific Ocean.<\/p>\n<p>There are now 39 square miles of exposed lakebed scraped raw by wind. And it&#8217;s toxic. This dust causes severe asthma in local towns like Calipatria.<\/p>\n<p>Yet, the south end of the lake is <strong>alive with escaping steam causing bubbling mud pots<\/strong>. There are cracks in the Earth&#8217;s crust that release 700-degree Fahrenheit fluid.<\/p>\n<p>It looks like something off the surface of the moon. What else sits in the land other than super hot, pressurized water?<\/p>\n<h2>$540 billion in mineral treasure<\/h2>\n<p>The deposits under the died-up Salton Sea are valued at $540 billion. Officials have <strong>nicknamed the region the Saudi Arabia of lithium<\/strong>.<\/p>\n<p>The Department of Energy estimates the basin holds 3,400 kilotons of the metal. Enough to power 375 million electric vehicles.<\/p>\n<p>Now, an engineering race is underway. Major players like Energy Source Minerals are already drilling, processing a staggering <strong>50,000 gallons of brine each minute<\/strong>.<\/p>\n<p>But the <a href=\"https:\/\/www.ecoportal.net\/en\/lithium-reserve-appalachians-energy\/21757\/\">operational reality is harsh<\/a>.<\/p>\n<p>The fluid is highly acidic, corrosive, and incredibly hot. Geologists compare the extraction process to <strong>trying to drink from a fire hose<\/strong>.<\/p>\n<p>Advanced filtration systems isolate the lithium, turning the thick, rust-colored brine into a clear liquid. Yet, that distinct rusty color hints at a dense cocktail of other concentrated elements left behind in the mix.<\/p>\n<p>The industry is <strong>planning to intercept the hidden material<\/strong>, but can they access the full payload?<\/p>\n<h2>More than a lithium rush: The stakes are high<\/h2>\n<p>The reason behind the thick, rust-colored brine has become clear. What other minerals are available for harvesting?<\/p>\n<p>The deep-earth payload contains huge, <strong>commercially viable concentrations of manganese and zinc<\/strong>.<\/p>\n<p>This isn&#8217;t just a lithium rush. It is a multi-metal extraction bonus.<\/p>\n<p>The strategic stakes are high. <strong>Drawing manganese and zinc<\/strong> directly from the geothermal fluid alongside lithium could <a href=\"https:\/\/www.ecoportal.net\/en\/one-mine-to-meet-worlds-battery-hunger\/15573\/\">rewrite American mineral independence<\/a>.<\/p>\n<p>It allows immediate recovery without traditional, destructive mining.<\/p>\n<h3>The local human impact has to be considered<\/h3>\n<p>Community leaders like Luis Olmedo of Comite Civico del Valle are fighting to<strong> ensure locals aren&#8217;t left behind<\/strong>.<\/p>\n<p>The region is one of the poorest in the nation and the locals have to live with a strong sulfur smell and severe air pollution.<\/p>\n<p>Advocates demand that profits from this $540-billion-dollar bonanza <strong>fund the cleanup of the exposed lakebed<\/strong>. They want stable, long-term infrastructure jobs for residents who have endured empty promises for decades.<\/p>\n<p>If these companies can successfully scale this direct extraction technology, they will do <strong>more than just power the EV transition<\/strong>.<\/p>\n<p>They will clean up a toxic wasteland and redefine <a href=\"https:\/\/www.ecoportal.net\/en\/2000000-tonnes-waiting-in-the-desert\/15407\/\">how we harvest raw materials from the earth<\/a>.<\/p>\n<p>The ultimate question is <strong>whether this green treasure will finally save the valley<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The largest lake in California was accidental.&nbsp; The Salton Sea was once a playground for Hollywood stars.
