The three executives, including CEO Terry Holohan, were freed from detention on Wednesday.
The billionaire was charged with participating in a scheme that involved paying more than $250 million in bribes to Indian government officials.
The resource is "one of the highest-grade open-pit gold resources in Canada owned by an exploration company," its CEO says.
Over the next five years, the South Korean government is expected to invest C$20 million towards the project.
