Lithium Mining is a Hot Topic In Nevada Thanks to Tesla
Lithium mining is suddenly a hot topic in Nevada, where a local state senator is up in arms about a deal to import lithium from Mexico. Other sources exist.

Lithium mining has become a hot topic in Nevada largely because of Tesla’s interest in sourcing lithium hydroxide, one of the main ingredients needed for Gigafactory scale production of lithium-ion batteries.
Tesla announced it had signed a deal with Canadian company Bacanora and British company Rare Earth Minerals towards the end of August. Bacanora is a minerals explorer, while Rare Earth Minerals owns Sonora Lithium Project. That partnership is designed to develop a “low-cost”, “sustainable” mining project in Northern Mexico based on clay deposits found in the region.
The Sonora mine does not exist yet, but could yield between 35,000 and 50,000 tons of lithium deposits annually. The deal will be extended and scaled up contingent on the mine’s ability to meet Tesla’s forecasts and actual output from its Gigafactory. The two Sonora project partners will need to find debt or equity to finance the operation and Tesla is permitted under the deal to participate in financing activities.
The state of Nevada has agreed to give Tesla almost a half billion dollars in tax incentives in order to lure the Gigafactory to the site north of Reno, which seems little enough considering the increase in economic activity the factory will bring to the state. But now, a Nevada politician, Democrat state senator Tick Segerblom, has tweeted, “Tesla to get lithium from Mexico – where’s Trump when you need him?”

That got the Las Vegas Sun involved. They contacted Elon Musk, who tweeted back that press interest in the story was “unwarranted” as the lithium deal was “not exclusive” and had “many contingencies”. He said that Tesla would “definitely” be interested in talking to local suppliers of lithium feedstocks. According to the Sun’s sources, developing lithium mines in the US is a lengthy process taking as much as 10 years, while lithium mining operations already located in Nevada are either too small or nearing the end of their planned lifetime.
@ScottLucasNV Lithium deal is not exclusive & has many contingencies. The press on this matter is unwarranted.

Now up pops Nevada Sunrise Gold Corporation, which apparently is a played out gold mining operation. It announced on September 2nd that it has “entered into a letter agreement for an option to purchase” a site in Esmeralda County, which is in Nevada’s Clayton Valley. The company believes that area could hold lithium brine deposits in subterranean aquifers, based upon studies and reports made of the local area.
Meanwhile, researchers at the University of Wyoming report they have discovered an enormous supply of lithium at the Rock Springs Uplift, a geological feature in southwest Wyoming. Initial tests indicate the lithium-rich brine from a 25-square-mile area could contain 228,000 tons of the stuff. That’s enough to meet annual U.S. demand and is twice the amount available at Silver Peak in Nevada, which is the biggest domestic lithium producer today.
What has the University of Washington team excited is that the lithium at the Rock Springs Uplift can be processed more cheaply than the lithium found at other locations, due to a number of factors.
First, extracting the lithium from brine requires large quantities of soda ash (sodium carbonate). The Rock Springs Uplift site is located within 30 miles of the world’s largest industrial soda ash supplies, so the cost of transporting it to the production area will be minimal.
Second, magnesium must be removed from brine before it can be used for lithium recovery and that can be an expensive process. The brine from the Rock Springs Uplift reservoirs is lower in magnesium than at other sites. Less magnesium means less money to remove it.
Third, the brine must be heated and pressurized to release the lithium it contains. Because the Rock Springs Uplift brine is far underground, it is already at a higher pressure and temperature than brine at existing lithium operations. That factor may eliminate an expensive step in the process, resulting in significant cost savings.
The Chinese thought they had cornered the market for lithium when they locked up rights to much of the world’s lithium supply located in Bolivia a decade ago. But apparently, the demand has created interest in new sources of supply. Hopefully, all this interest in lithium will spur competition which could lead to lower prices. And that could spell lower battery prices for the electric cars and electrical storage batteries of the future.

Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
