A Nevada lithium mission central to US efforts to safe home mineral provide is leaning on a half-century-old satellite tv for pc program for contemporary solutions.
The Geological Survey’s Landsat program, managed with NASA, has supplied steady Earth observations since 1972. Its freely accessible photographs enable scientists and business leaders to measure panorama modifications with precision.
In northern Nevada, these insights are proving essential as Lithium Americas works to advance Thacker Cross in a method that meets strict environmental and land-use requirements.
“Landsat imagery is efficacious for vital minerals mission improvement as a result of it offers constant, long-term knowledge that doc land use modifications and geological options, assess environmental receptors and help planning choices,” mentioned Alexi Zawadzki, president of North American operations for Lithium Americas (NYSE:LAC), in a USGS report.
When planning started, Landsat knowledge revealed that the unique mine website overlapped with vital sage-grouse habitat.
Though the fowl just isn’t a protected species, its sharp inhabitants decline for the reason that Sixties has made it an indicator of ecosystem well being in Nevada’s rangelands. The discovering prompted builders to shift the mission six miles south, away from prime territory.
Water use is one other vital problem confronted by the mission. Landsat knowledge has been paired with discipline checks to estimate groundwater ranges, utilizing variations in vegetation to deduce depth.
With this knowledge, the Thacker Cross mission goals to recycle processed water as much as seven instances and to function as a “zero liquid discharge facility.”
Not like conventional lithium brine operations, the mission will extract lithium from clay deposits. Tailings shall be saved in dry services and later reused for reclamation work.
Financial promise
Lithium Americas estimates development of Thacker Cross may generate greater than US$700 million yearly and help 1,800 jobs. As soon as operational, financial exercise linked to the mine may common US$2.1 billion per yr, in keeping with a College of Nevada, Reno examine.
Lithium is a cornerstone of batteries that energy smartphones, laptops, and electrical automobiles. The US ranks third globally in identified lithium sources however stays depending on imports.
As a result of useful resource’ rising significance, creating home provide has grow to be a matter of each industrial coverage and nationwide safety.
Landsat’s worth, is hardly confined to mining. A 2023 financial evaluation positioned its annual contributions to US industries at US$25.6 billion, spanning all the pieces from gold exploration to lowered insurance coverage prices for farmers.
For Thacker Cross, the check will come as mining will get underway. However for now, the view from house has already reshaped how the mission is deliberate and envisioned transferring ahead.
By making use of Landsat knowledge, planners hope to point out that useful resource extraction and environmental stewardship can advance collectively.
