Portugal Metal Reserves

USGS reports 2 commodities with a reserve or production figure for Portugal, led by Lithium at 0.86% of the reported global reserve.

USGS assesses roughly 90 mineral commodities worldwide each year, but only compiles a country-level reserve or production breakdown for a given commodity where the underlying data supports one — the table below is every commodity that condition is met for in Portugal. Each row pairs the reserve quantity with its share of the reported global total and last year's production, so it's possible to see at a glance which commodities this country is significant in and which it merely reports a smaller figure for.
