This field trip guidebook was prepared for the 100th Anniversary Meeting of the Society of Economic Geologists originally planned to be held in Whistler, British Columbia, September 15–18, 2020. The meeting was postponed because of the global COVID-19 pandemic and was rescheduled to September 14–17, 2021, but the field trips were canceled due to travel uncertainty at the time. Victoria Gold Corp. (Eagle mine), Alexco Resource Corp. (Keno Hill district), Pembridge Resources (Minto mine), Copper North Mining Corp. (Carmacks Copper deposit) and Triumph Gold Corp. (Mount Freegold district) generously agreed to host the field trip and enabled their geologists to contribute to this guidebook. Anyone wanting to follow this guidebook is advised to contact the companies regarding access.
