We present a detailed assessment of world lead-zinc mineral resources, showing at least 226.1 Mt Pb and 610.3 Mt Zn

The dominant mineral deposit type is sediment-hosted Pb-Zn deposits, containing 141.6 Mt Pb and 345.1 Mt Zn

Companion metals, such as scandium, indium, tungsten and others can add substantial potential economic value to a deposit

Tailings could represent a future resource but remain technically challenging

Economics, environmental impacts and social concerns are the real constraints to Pb-Zn’s future – not just how much is left
