The U.S. defense industrial base is 100% reliant on imported magnesium
Calling our dependence on imported magnesium is not a supply chain risk. It is a single point of failure. But Magrathea is the only credible project building domestic magnesium production capacity and removing our country’s reliance on imports.

Three months to industrial paralysis.
The hidden shortage begins
Car-part plants, aluminum mills, and defense suppliers start burning through stocks. Nobody at home notices yet.
The panic hits trading desks
Factories learn the truth, their suppliers cannot replace Chinese magnesium. Contracts break. Force majeure notices go out.
The shutdown reaches Main Street.
Auto plants stall. Aircraft lines slow. Aluminum parts disappear. Repair prices spike. Defense production starts rationing inputs.
America discovers there is no backup plan
New magnesium capacity cannot appear on command. Washington can print money, but it cannot print metal.
The United States has had no domestic primary magnesium smelting capacity for years
Magnesium Production in 2026
Currently, China controls a staggering 95% of global primary magnesium production.
This concentration is not a theoretical risk. China has cut off magnesium supply twice already this century, just as it did recently to rare earths. It’s time to take matters into our own hands.
When China cuts us off again, the aluminum industry will cease operations within months, followed shortly by automotive and aerospace manufacturing.
There is no aluminum alloy production, no domestic titanium production, and no steelmaking desulfurization without it. This will decimate the American economy.
Magnesium is formally designated a critical mineral
It is in the same strategic category as rare earth elements, gallium, germanium, scandium, and antimony. Industrial processes need magnesium in far greater volumes, and there is zero US production capacity to fall back on.
The reason Western production capacity disappeared is not because a natural resource ran out
Magnesium salts are abundant in the U.S. Western production capacity halted not because the material ran out, but because no one has fully developed the processing technology needed to produce magnesium economically outside China. Until today.
Magrathea was built to achieve this. Our new generation of dehydration technology resolves the specific processing challenges that previously caused every Western magnesium project to fail, whether on cost, operational, or permitting grounds. Our technology makes rebuilding domestic supply commercially viable for the first time in years.
