The Diavik diamond mine is Canada’s largest diamond mine, located on a 20 square kilometre island at Lac de Gras, Northwest Territories, approximately 300 kilometres from Yellowknife. The mine is 60% owned, and operated, by Rio Tinto plc and is 40% owned by Dominion Diamond Corporation.
Diavik began producing diamonds in January 2003, and has since produced just under 100 million carats (“Mcts”) from three kimberlite pipes (A154 South, A154 North, and A418). Rio Tinto plc has recently approved the development of open pit mining from a fourth pipe (A21). The kimberlite pipes at Diavik are exceptionally high-grade in nature, making it one of the most profitable diamond mines in the world. The current mine plan is expected to take the mine’s production to at least 2023.
Sandstorm has a 1.0% gross proceeds royalty on the production from the Diavik mine. Sandstorm acquired the royalty from IAMGOLD Corporation in March 2015 for US$52.5 million in cash and 3 million warrants of Sandstorm. The warrants have a 5 year term, a strike price of US$4.50 per Sandstorm common share and will be exercisable following the initial production from the Diavik Mine A21 pipe.
