About Collective Mining Ltd.

Founded by the team that developed and sold Continental Gold Inc. to Zijin Mining for approximately $1.4 billion in enterprise value, Collective is a gold, silver, copper and tungsten exploration company with projects in Caldas, Colombia. The Company's two projects are located directly within an established mining camp with ten fully permitted and operating mines.
