AVERAGE COPPER MINING GRADES CHILE VS WORLD 2005-2016 • Average Ore grades of the sulfide line have decreased similarly (27%), Chile and the World. • Ore grades of the oxides line in Chile are lower than the world average. • There is a depletion of oxidized resources in Chile, which will mean 66% lower production of SX-EW cathodes by 2027.

Although by 1810 Chile was producing 19,000 m.t./yr of copper from oxidized ores, copper mining did not dom-inate until 1840, when reverberatory furnace technology was introduced to process sulfurous ores. At that point, Chile became the largest copper producer worldwide, producing a total of more than 2 million m.t. of copper
