Minerals
Every mineral Earthern tracks, ranked by Earthern Strategic Score across supply concentration, substitutability, demand growth and jurisdictional risk.
Neodymium
A light rare earth element and the backbone of high-performance NdFeB permanent magnets.
Dysprosium
A heavy rare earth added to magnets to preserve performance at high operating temperatures.
Copper
Copper is the primary conductor of the electrified economy, used wherever electricity or heat must move efficiently.
Terbium
A scarce heavy rare earth used in high-temperature magnets and phosphors.
Gallium
A soft metal recovered as a by-product of aluminium refining, essential to compound semiconductors.
Uranium
The fuel of nuclear fission and the densest practical energy source available to civilisation.
Germanium
A metalloid recovered from zinc residues and coal fly ash, critical to infrared optics and fibre.
Praseodymium
A light rare earth usually produced and traded jointly with neodymium as NdPr oxide.
Antimony
A metalloid used in flame retardants, lead-acid batteries and increasingly in defence and energy storage.
Lithium
The lightest metal and the irreplaceable charge carrier in current lithium-ion battery chemistries.
Tungsten
The metal with the highest melting point of all elements, essential for cutting tools and armaments.
Graphite
Crystalline carbon and the dominant anode material in every commercial lithium-ion cell.
Silicon
Refined from quartz into metallurgical, solar and semiconductor grades of extraordinary purity.
Cobalt
A cathode stabiliser that improves battery energy density and cycle life, produced mostly as a copper by-product.
Silver
The most electrically and thermally conductive element, and a dual monetary and industrial metal.
Platinum Group Metals
Platinum, palladium, rhodium, iridium and ruthenium — exceptional catalysts with extreme scarcity.
Nickel
A corrosion-resistant metal essential to stainless steel and to high-energy-density battery cathodes.
Manganese
An essential steel additive and a growing battery cathode component.
Potash
Potassium salts that supply one of the three primary nutrients in agricultural fertiliser.
