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
