"In many commodities, especially copper, there is limited new supply and it takes 10 years and several billion dollars to develop a new significant mine.

This gave us the buying opportunity we were looking for. The focus of the company on copper and coal also was very attractive because of the strong demand and sustainably high margins, and because the company was moving very aggressively to reduce its costs."

During that same period, Lundbergs' average annual total shareholder return was nearly 16%.
