Winston Score History

The full picture

Antofagasta is a mining company that digs copper out of the ground in Chile. Copper is a metal used in electric wires, cars, and buildings, so Antofagasta's main customers are manufacturers and industrial buyers around the world. The company is one of the largest pure-play copper producers globally and is controlled by the Chilean Luksic family.

Antofagasta makes money by selling copper, along with smaller amounts of gold and molybdenum that come out of the same mines. It operates entirely in Chile, which holds some of the world's richest copper deposits, giving the company a natural resource advantage. However, Chile also brings risks — the government has discussed raising mining royalties and taxes, which could reduce profits. The bigger long-term driver is demand for copper from electric vehicles and clean energy infrastructure, both of which require far more copper than traditional technology.
