This is not an even scatter of copper icons across the world map. Two regions carry the overwhelming weight of global copper supply, and they fail — or could fail — for two structurally different reasons.
---
The Copperbelt is the second-largest copper reserve on Earth — roughly half of Chile's, concentrated in one geographical strip.
Fragility Mark: Political and Economic Disruption
Chile is the densest mark on this map: production and reserve leader, and home to the world's single largest copper mine.
Key Site: Escondida
Cost Mark: Environmental and Resource Constraint
The Gawler Craton (Olympic Dam-adjacent copper-gold province) is real but deliberately kept small in this analysis — it is not dominant.

| Mark | Meaning | |------|---------| | ############# | Density of mark correlates with scale of production/reserve; denser block = larger real share | | * name | A specific, individually-named mine cited directly from source (e.g., Escondida) | | [FRAGILITY MARK] | Vulnerability by POLITICAL/ECONOMIC DISRUPTION — price-crash history, war-severed transport routes. The ore is there; getting it to market has failed before and could again for non-geological reasons. | | [COST MARK] | Vulnerability by ENVIRONMENTAL/RESOURCE COST — water consumption, desalination requirement. The ore is there and the route out is intact; what is scarce is what extraction spends to get it. |

Chile and the Central African Copperbelt are not the same kind of "strong" region wearing different geography.
Chile is geologically and logistically secure — its risk is what extraction costs the water table, a slow-moving, engineering-solvable constraint (desalination is already in use).
The Copperbelt is geologically rich — nearly half of Chile's reserve, concentrated in one strip of land — but has already been gutted once by a price collapse and once by a severed transport link. Its risk is political and infrastructural, sudden rather than gradual, and not solved simply by better engineering at the mine face.
Two regions carrying the world's copper. Two different reasons either one could stop delivering it — cost that rises slowly, or a route that can be cut all at once. The map keeps them named separately, because collapsing them into one generic "copper is at risk" mark would erase the actual difference between an environmental bill coming due and a bridge that has already been blown up once.
Gawler Craton (Australia) is shown small and deliberately secondary — real reserve, not dominant — to make clear the two-region argument is a finding about where the weight actually sits, not an artifact of only having looked at two places.
