My good friend Pierre Lassonde, cofounder and chairman of Franco-Nevada, doesn’t know how we’ll replace the massive gold deposits of the past 130 years or so. Speaking with the German financial newspaper Finanz und Wirtschaft this month, Pierre says we’re seeing a significant slowdown in the number of large deposits being discovered. Legendary goldfields such as South Africa’s Witwatersrand Basin, Nevada’s Carlin Trend and Australia’s Super Pit—all nearing the end of their lifecycles—could very well be a thing of the past.

Over the medium and long-term, this could lead to a supply-demand imbalance and ultimately put strong upward pressure on the price of gold.

“It doesn’t really matter what the gold price will do in the next few years,” Pierre says. “Production is coming off, and that means the upward pressure on the gold price could be very intense.”
