A Huge American Lithium Discovery | Earth Wise

October 12, 2023 By EarthWise Leave a Comment

A huge discovery of lithium in the United States

Human history has often been described in terms of a succession of metal ages:  the copper age, the bronze age, and the iron age.  In many ways, we have now entered the lithium age.  The light metal goes into the batteries that power smartphones, electric vehicles, and massive storage banks for the power grid.  Lithium has become a critical strategic resource.

As it stands now, the U.S. gets most of its lithium from imports from Australia and South America.  Major lithium sources are not commonplace; in 2022 there were only 45 lithium mines in the world.  Many of the known deposits are not in North America but in Chile, Bolivia, Argentina, China, and Australia.  The current largest known lithium deposits lie beneath the salt flats of Bolivia.

Lithium Americas Corporation, a company dedicated to advancing lithium projects to the stage of production, funded research over the past decade that has identified vast deposits of lithium-rich clay in a dormant volcanic crater along the Nevada-Oregon border.  The McDermitt Caldera is estimated to hold between 20 and 40 million tons of lithium, which would make it the largest deposit in the world.

There are many questions still to answer.  It is not clear how easy it will be to extract lithium from the clay, in particular how expensive or carbon-intensive it will be.  There are also political complexities since the area where the lithium deposit was found is considered to be unceded ancestral land for both the Paiute and Shoshone tribes.

Apart from a dearth of domestic sources of lithium, the US also lags well behind China in lithium processing capabilities.  The country has catching up to do in the new lithium age.

Falling Lithium Prices | Earth Wise

May 1, 2023 By EarthWise Leave a Comment

Producers still working out how to meet the surging demand for lithium

Lithium, the key element in the batteries that power electric cars, as well as smartphones, tablets, and laptop computers, is sometimes called white gold.  Over time, the price of the metal has gone up and up.  But recently, and surprisingly, the price of lithium has actually gone down, helping to make electric vehicles more affordable.

Over the first couple of months of this year, the price of lithium has dropped by nearly 20%.  The price of cobalt, another important component of vehicle batteries, has fallen by more than half.  Even copper, another battery material, has seen its price drop by 18%.

Many analysts predicted that prices of these commodities would stay high or even climb higher.  The reason for the decline, as well as whether it is likely to persist, is the subject of much debate.

Some experts believe that the price drops are a result of demand not being as high as expected, perhaps related to slowing sales growth of EVs in Europe and China after certain subsidies expired.  Other industry experts said that the drop was a result of new mines and processing plants providing additional supply sooner than was thought possible.

Despite the price drops, mining and processing lithium remains an extraordinarily profitable business.  It costs from $5,000 to $8,000 to produce a ton of lithium that sells for ten times that amount.  With such fat profit margins, there is no shortage of banks and investors eager to finance lithium mining and processing projects.  Such profit margins are probably not sustainable and that will likely result in more reasonable prices over time.

There is plenty of lithium in the world.  The huge demand for it is a recent phenomenon and the world is still working out how to meet that demand.

Organizers of the Tokyo 2020 Olympic Games announced in February that all the Olympic medals for the games will be made from recycled materials.  The strategic roadmap for the games, laid out in the document “Olympic Agenda 2020”, specifically calls for the inclusion of sustainability in every aspect of the games.
