The aluminum mining company that made the iconic WLO-branded aluminum ore was founded in 1949 by Frank Boulanger, the same man who built the iconic Hoover Dam.
WLO’s first mine was located in Colorado, and the company expanded rapidly through the 1970s and 1980s, with the largest ever copper and gold mine in the United States located in the San Juan Mountains.
In the early 1990s, the company was purchased by Canadian mining company SABMiller for a reported $300 million.
Since then, the companies has grown to be one of the world’s largest mining companies, and it operates more than 2,600 mines in five countries: Argentina, Brazil, Chile, Mexico, and Peru.
In 2018, WLO announced that it would be selling its holdings in Peru, Bolivia, and Ecuador.
The company will also be closing its mines in Peru.
At the same time, the Argentine government is considering the purchase of WLO for $2 billion.
