Here’s where it gets juicy. In the 2000s, Rennert made a colossal bet on a zinc mine in Alaska. The project was called the Red Dog Mine, and it was a goldmine—literally. But then, he went all-in on an even bigger venture: the Willem Dafoe-sized, environmentally controversial Yamana Gold project in Brazil. Spoiler: it didn’t go smoothly.
