Pick a material, a stage and the country to depend less on. The tool lists every other producer in the same source table, how large it is without that country, and what else the atlas knows about it.
Without Chile, the other listed countries hold 63.9 % of world mining output of copper.
This is arithmetic on one source table, not a forecast. It leaves out prices, stocks, substitution, new mines and how fast anyone could react.

Share of world reserves: Reserves, 2025· Export control on record:
HHI is the sum of squared country shares (10,000 = one country). Where the table leaves part of world output unattributed, it is a lower bound.
13.0 % of world output in this table is not attributed to a country and stays outside the calculation.
