Finding the chokepoint
A supply chain's true constraint is rarely the most obvious bottleneck. Here is how to locate the stage that actually sets…

The battery supply chain end to end
From a lithium brine pond in the Atacama to an EV on a European road, battery materials cross four continents and one…

The magnet supply chain end to end
Mining rare earths outside China addresses only the first of five distinct steps needed to put a finished permanent magnet…
What a chip is made of
A modern logic chip draws on dozens of elements, each refined to purities that would have seemed impossible a generation…

Substitution: the quiet force
When engineers replace a metal in a product, the effects travel upstream through the supply chain to the mines that depend…

Stockpiles and strategic reserves
Stockpiles and strategic reserves explained: who holds them, how they work, and what they cannot do when supply chains…

How metals are priced
Metals are priced in three distinct ways — exchange trading, benchmark negotiation, and price assessment — each suited to…

Reserves are not resources
Reserve and resource mean precisely defined things in mining codes. Confusing them distorts every supply calculation built…

Reading a technical report
What JORC and NI 43-101 actually mean, and how to read the resource and reserve categories quoted in technical reports.
Cost curves and who survives a downturn
Why the same metal price that bankrupts one mine leaves another comfortably profitable, explained through cost curves and…

What makes a mineral 'critical'
How governments classify minerals as 'critical', why their lists diverge, and what the label actually changes in practice.

Export controls and resource nationalism
How export bans, quotas, licences and processing requirements reshape mineral supply chains — and what each tool actually…

Crushing, grinding and flotation
How rock becomes concentrate: the crushing, grinding and flotation steps that turn low-grade ore into a saleable product.

Smelting and refining
How metal concentrate is converted to refined metal through smelting and refining, and what by-products emerge along the…

Leaching and hydrometallurgy
How acid, pressure and solvent extraction dissolve and separate metals from ore — the core steps of hydrometallurgical…

Separating the rare earths
Rare earth elements share nearly identical chemistry, making separation one of the most stage-intensive processes in…

What purity actually means
Purity grades in materials processing run from commercial to nine-nines. Each extra nine reshapes cost, process design, and…

By-products and companion metals
Most metals never have their own mines. Understanding why reveals how supply chains for dozens of elements actually work.
