Lithium mine near Tesla Gigafactory plans to break ground as global shortage rears head
Just 150 miles north of Tesla’s Gigafactory, a plan is brewing to a build a massive mine capable of growing the world’s lithium carbonate supply by a full 15% as early as 2022 and more than 20% by 2026, compared to 2018. Tesla could, in other words, find itself neighbors with one of the largest concentrated supplies of lithium carbonate in the world less than a decade from now.
Known as Lithium Americas, the company behind the study has conservatively estimated that it could break ground on its prospective Northern Nevada Li2CO3 mine as early as the end of 2020 and ramp up to an annual output of 30,000 metric tons of the basic Li-ion battery precursor just 21 months after that. The mine’s output would then double by 2026, coming to rest at a maximum annual lithium carbonate output of 60,000 tons.
Theoretical estimates conducted by a number of academic parties in the 2010s have shown that any given high-quality lithium-ion battery would be expected to require 2-3 kilograms of lithium carbonate per kWh of final capacity, although the absolute physical minimum is closer to 0.4 kg. To sustain Gigafactory 1’s 35 GWh 2018 production goal, that single factory alone could require between 60,000 and 85,000 tons of lithium carbonate annually to sustain its battery production operations alone.

To put this requirement in context, the entire global supply of lithium carbonate is expected to peak at ~250,000 tons in 2018 after astounding YoY production growth of 21.5% from 2016 to 2017 – Tesla’s demands this year could thus easily swallow 25-30% of the entire global lithium carbonate supply.
Despite those staggering numbers, Gigafactory 1 production is still expected to ramp (albeit based on optimistic 2016 Elon Musk numbers) as high as 105 GWh of cells and 150 GWh of packs annually by the time it is fully completed, likely a few years after the original 2020 estimate. Roughly 7 times the volume of Tesla’s 2018 production goals for the massive factory, sustaining that final volume of production (255 GWh annually) would literally require the global supply of lithium carbonate to grow by a bare minimum of 250% in less than half a decade. To reiterate, that is for a single Gigafactory, of which Tesla plans to construct several more in China, Europe, and elsewhere.

Put simply, Tesla is going to need every ounce of lithium supply they can get their hands on, and Lithium Americas’ prospective Nevada offering could theoretically supplement that total required supply by as much as 10% by the mid-2020s. Tesla, however, is already hard at work attempting to secure a strong and satisfactory supply of lithium and other rare earth metals and materials required to produce premium-grade Li-on batteries.
Tesla already has agreements to buy lithium from a somewhat smaller Nevadan effort from Pure Energy Minerals (phase 1 production NET 2020) and Bacanora’s Sonora Lithium prospect (NET 2020), lithium hydroxide (a product of lithium carbonate) from Australian upstart Kidman Resources (NET 2021), and also plans to invest directly in lithium heavyweight SQM to strengthen a foothold in Chile, the current owner of ~50% of the world’s lithium mining rights.
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’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.
