Lithium in Pyrite, Revisited: The Supply Story Catches Up to the Thesis

Two years ago, I wrote about an obscure but intriguing discovery: West Virginia University researchers had found meaningful lithium concentrations in pyrite within Appalachian shale formations. At the time, lithium prices were deep in a slump, the EV “bubble” narrative was everywhere, and the idea of investing in a decade-long domestic lithium project sounded, to most readers, like a solution in search of a problem.

That problem just showed up.

The Numbers Now

Battery-grade lithium carbonate has surged roughly 95 percent since early December, climbing from about $13,400 per metric ton to more than $26,000 per ton by late January 2026, levels not seen since 2023. The drivers are familiar to anyone who has watched commodity cycles before: production delays at major Chinese operations, tightening permits in Jiangxi province, and demand that simply did not slow down the way the bears expected.

That last point matters most. The 2024–2025 downturn was supposed to be the new normal: a multi-year surplus, oversupplied mines, sodium-ion batteries waiting in the wings to make lithium less essential. Instead, demand for lithium in stationary energy storage jumped approximately 71 percent in 2025, with another 55 percent growth forecast for 2026. Analysts at Morgan Stanley and UBS are now projecting a supply deficit for the year, not a surplus.

Yet the recent price rebound did not emerge from an unforeseeable shock. It emerged from conditions that were visible throughout the downturn. Demand continued growing. Supply remained geographically concentrated. New production faced regulatory, geological, and financial constraints. What changed was not the underlying reality. What changed was the market’s willingness to ignore it.

Why This Matters Beyond the Spreadsheet

I did not write the original piece because I had a hot take on commodity prices. I wrote it because the pyrite discovery was a small example of a much larger pattern: the United States treats domestic resource development as optional until the market forces the issue, and by then the lead-time problem becomes a strategic problem.

The deeper issue is that markets and governments operate on different timelines. Commodity markets can reverse in months. New mines, refineries, processing facilities, and workforce pipelines take years. By the time a price spike reveals a strategic vulnerability, the window for a rapid response has already closed.

The pyrite-to-lithium pathway is still early. The researchers were clear in 2024 that commercial viability was a decade-plus proposition, contingent on leaching technology, acid drainage mitigation, and pilot-scale validation.

None of that has changed. The science still requires validation. The economics still require scale. The timelines are still measured in years.

What has changed is the cost of waiting.

The United States opened its first domestic lithium refinery in Texas this year and has been stockpiling critical minerals as a deliberate response to exactly this kind of volatility. Those are sensible steps. The challenge is that they are largely reactive. They occur after markets have already signaled a vulnerability rather than before.

The Appalachian basin, with its existing mining infrastructure, displaced coal workforce, and now a plausible secondary lithium resource, is the kind of asset that should have been part of the conversation years ago.

Supply Chains and Sovereignty

This is not merely an economic story. Supply chains are systems of dependency.

Every nation eventually discovers which resources it can safely import and which capabilities it must retain for itself. Critical minerals increasingly appear to belong in the latter category.

The market spent much of the last two years treating lithium abundance and lithium security as the same thing. They are not. A resource can be globally abundant while remaining strategically vulnerable if production, refining, or processing capacity is concentrated in too few places.

That distinction matters because supply shocks do not ask whether a nation possesses a resource somewhere within its borders. They ask whether that nation can access, process, and deploy that resource when it matters.

The Pattern Repeats

This is not really a story about lithium.

It is a story about how slowly institutions move relative to market reality, and how often decision-makers dismiss early signals because those signals do not yet resemble a crisis.

Two years ago, the pyrite discovery was a curiosity. Today, with prices nearly doubling in a matter of months and deficit forecasts replacing surplus forecasts, it looks more like an opportunity that was available the entire time.

The United States will eventually diversify its lithium supply chain. The economics will force that outcome. The real question is whether diversification happens before the next supply shock or because of it.

Markets are remarkably good at identifying shortages.

They are far less effective at reducing the years required to solve them.
