developing tier 1 supply of low cost, low carbon metal for the era of decarbonization

Finally, secure Western supply

Magrathea sells metal from and to countries with enforceable contract law. Flexible contracts that match industry needs allow our partners to build in magnesium with confidence. We help eliminate price volatility from Chinese market manipulation so innovative products of our partners can succeed.

Eliminating mining eliminates project risk

Greenfield resource projects take up to a decade for exploration, mine planning, and process development. Negative cashflows have to go into the ground before any product is sold, reducing project NPV. Magrathea’s metal projects pull positive cashflows forward and eliminate development risk by eliminating mining.

enabling the next century of Western dynamism

The 2020s are a precarious decade of great power conflict. More than 90% of magnesium is produced in China, Russia, and Iran despite its use across a variety of high performance defense applications. We’re building a supply base of magnesium in the US, Europe, and Australia that strengthens our shared security.

The only carbon neutral metal anytime soon

Magrathea takes a technology first approach to low cost, low carbon metal. We’re piloting a new generation of electrolytic production technology that is inherently carbon neutral, removing the need for coal and carbon-intense reagents like Al, Si, FeSi and SF6. We delete process complexity to cut opex and capex.

ocean metal is the civilization scaling metal

As civilization expands on and off Earth, we’ll preserve our home planet’s natural capital like rainforests and indigenous ecosystems by minimizing mining. Aluminum and steel are condemned to cost structures unprotected from declining ore grades and purities which necessarily increases cost over time.
