Mining

Overview

Mining is the industry that extracts raw metals, minerals and coal from the earth, forming the very first link in the supply chain for every product on this site — no metal price exists without a mine somewhere producing the underlying material. Individual mining operations range enormously in scale, from vast open-pit iron ore or copper mines processing hundreds of thousands of tonnes of rock a day down to smaller underground operations targeting narrow, high-grade veins of gold or silver.

What unites the industry despite that variety is its position at the start of every metal's journey: a mine produces ore, which then moves through processing, smelting or refining, before finally reaching manufacturers as usable metal. Disruptions at the mining stage — weather, labour action, regulatory delay, equipment failure — tend to echo forward through every later stage of the supply chain, which is why mine-level news so often moves metal prices even before any shortage is actually felt by end users.

Extraction Methods

Open-pit mining, used for ores close to the surface, removes overlying rock in progressively larger benches to expose ore that's then hauled out by truck — the method behind most large-scale iron ore, copper and coal operations because it allows for high-volume, relatively low-cost extraction. Underground mining, by contrast, is reserved for deeper or narrower deposits where stripping away surface rock wouldn't be economical, and it typically costs more per tonne extracted but can access higher-grade material inaccessible to open-pit methods. Placer or alluvial mining, used mainly for gold and some gemstones, recovers metal that has already eroded out of its original rock and settled in riverbeds or sediment, requiring far less blasting and crushing than hard-rock methods.

Economics and Market Role

Mining projects are unusually capital-intensive and slow to develop — it routinely takes a decade or more from an initial mineral discovery to a mine actually producing at scale, once exploration, permitting, financing and construction are all accounted for. That long lead time is a big part of why metal supply often responds sluggishly to even sustained price increases: miners can't simply switch on new production the way a factory can add a shift, so a genuine supply response to high prices can take years to materialise, while demand-side price swings happen in days. It's also why announcements like final investment decisions, mine restarts or new mineral discoveries — even years before first production — routinely move how traders price a metal's medium-term supply outlook.
