The above-mentioned mineralogy results in concentrate quality at above ~60% copper content. Finally, the copper rich minerals include significantly less iron, which drives a quality challenge at the process plant. Mines could slow down the gradual grade decline by removing a larger proportion of iron and gangue content from the concentrate.

Diminishing supply from currently operating mines combined with the projected increase in demand for copper concentrate over 2021-2030 would result in a 3.85-Mt production shortfall in 2025. This shortage will not be observed, however, as known late-stage copper projects will contribute to narrow the deficit.
