About Iris Fontbona
Iris Fontbona is the wealthiest person in Chile and one of the richest women in the world. She inherited the Luksic Group fortune following the death of her husband, Andronico Luksic, in 2005, and has since proven herself an exceptionally capable steward of the family's vast industrial empire. The Luksic Group is the largest private business conglomerate in Chile, with holdings spanning copper mining, beverages, banking, shipping, manufacturing, and real estate across Latin America and beyond.
The crown jewel of the Fontbona family empire is Antofagasta PLC, a London-listed copper mining company that operates some of the most productive mines in Chile's mineral-rich Atacama Desert. Under the family's continued oversight, Antofagasta has maintained its position as one of the world's premier copper producers, benefiting from the surging global demand for copper driven by electrification and the green energy transition. The company's disciplined approach to mining operations and environmental stewardship has earned it respect throughout the industry.
Fontbona and her three sons — Andronico, Jean-Paul, and Guillermo — have not only preserved the legacy of Andronico Luksic Sr. but have grown the family fortune significantly. Their holdings include Quinenco, a diversified industrial holding company; Banco de Chile, one of the country's largest banks; and CCU, a major beverage company. The Fontbona family's ability to manage and grow such a diverse empire across multiple industries and geographies is a testament to their business acumen and long-term vision.
