Mount Milligan Mine

● Mount Milligan mine began production (first feed) in the Fall of 2013

● Conventional truck-shovel open pit gold and copper mine and concentrator with a 62,500 tpd design capacity copper flotation processing plant

● 100-120 Kt mined per day, 15 m bench height, all waste material used in TSF construction

● At full capacity, the mine produces an average 250 dry tonnes per day of copper-gold concentrate (approx. 21% Cu, 60 g/t Au)

● current mine life of 21+ years

● Reserves of 467.9 Mt at 0.19% Cu, 0.3 g/t Au containing 1.94 Blbs Cu, 5.14 Moz Au (P&P)

Mount Milligan: Water Shortage

● Mount Milligan is currently experiencing a water shortage, largely because of consecutive years that were drier than expected and have resulted in a reduced amount of water flowing into the TSF during the spring melt

● We are seeking amendments to existing Mount Milligan mine permits and Environmental Assessment Certificate to allow us to use water from additional sources near the mine site

7

● In March 2018, we completed a pipeline to Philip Lake 1, which will provide the mine with a low volume of water for 2018

● Adaptive management approaches are being used to ensure environmental protection of the lake, including fish and fish habitat
