The Company is a joint venture partner with Appian Capital Advisory LLP for the advancement of one of Canada's premier past-producing zinc mining camps, the Pine Point Project, located in the Northwest Territories, for which the 2022 PEA (as defined herein) has indicated an after-tax NPV of C$602 million and an IRR of 25%, based on long-term zinc price of US$1.37/lb and the current mineral resource estimates that are amenable to open pit and shallow underground mining. The current mineral resource estimate in the 2022 PEA consists of 15.7Mt grading 5.55% ZnEq of Indicated Mineral Resources and 47.2Mt grading 5.94% ZnEq of Inferred Mineral Resources.
