Driving demand:
Defence
We live in uncertain but exciting times. Defence has become more of a priority than it has been for the past half-century, but technological innovations – AI and robotics, electrification and renewable power, and a multitude of smart gadgets – promise to reshape our world as a cleaner and more productive one.
This new world needs new minerals and industrial sectors are having to learn more about a family of vital but obscure metals like titanium, zirconium, hafnium, neodymium, praseodymium, dysprosium, and terbium.

Driving demand:
Technology
Demand for critical minerals is being driven by growth in advanced technology. Titanium is widely used in aerospace and industrial applications, while zirconium and hafnium are important for nuclear technologies, semiconductors and high-performance alloys. Rare earth elements neodymium, praseodymium, dysprosium and terbium are essential for the powerful magnets used in electric vehicles, wind turbines, robotics and electronics. As supply security becomes increasingly important, exploration projects targeting these minerals are attracting strong investor interest.
FUTURE-FACING METALS
What this future requires:
Titanium
Titanium’s Properties: High-strength, low-density transition metal known for exceptional corrosion resistance, high heat resistance, and biocompatibility
Stat: Titanium makes up some 40% of an advanced fighter jet’s structural weight
FUTURE-FACING METALS
What this future requires:
Zirconium
Zirconium’s Properties: Ductile transition metal with high corrosion resistance, density, and melting point
Stat: <1 mol% of zirconium oxide enhances the safety and performance of EV batteries
FUTURE-FACING METALS
What this future requires:
Hafnium
Hafnium’s Properties: Similar to zirconium in malleability, density and melting point and also generally hosted by the same minerals
Stat: 3D-stacked logic and memory integration needs ultra-thin layers of hafnium-based materials typically 2-12 nm to maintain high remanent polarisation and stability
FUTURE-FACING METALS
What this future requires:
Neodymium
Neodymium’s Properties: A soft REE that tarnishes rapidly in air but is highly reactive and recognised for forming the strongest permanent magnets available because of its high magnetic anisotropy
Stat: Up to 4kg of neodymium is needed for the actuators, joints and hands for humanoid robots
FUTURE-FACING METALS
What this future requires:
Praseodymium
Praseodymium’s Properties: A malleable and ductile lanthanide metal known for its magnetic and optical properties
Stat: Up to 35kg of praseodymium is needed in the batteries required to manage the workload and heat generated by a large wind turbine
FUTURE-FACING METALS
What this future requires:
Dysprosium & Terbium
Properties: Soft lanthanide metals that can be cut with a knife, characterised by a high melting point, strong magnetism at low temperatures, and stability in dry air. Crucially, they resist ‘demagnetisation’ at high temperatures
Stat: Just over 7mg of dysprosium allows your smart phone to work under intense heat and remain pocket sized
