About Collective Mining Ltd.

Founded by the team that developed and sold Continental Gold Inc. to Zijin Mining for approximately $2-billion in enterprise value, Collective is a gold, silver, copper and tungsten exploration company with projects in Caldas, Colombia. The company has options to acquire 100-per-cent interests in two projects located directly within an established mining camp with 10 fully permitted and operating mines.

The company's flagship project, Guayabales, is anchored by the Apollo system, which hosts the large-scale, bulk-tonnage and high-grade Apollo gold-silver-copper-tungsten system. The company's objectives are to improve the overall grade of the Apollo system by systematically drill testing newly modelled, potentially high-grade subzones, expand the Apollo system by stepping out along strike to the north and expanding the newly discovered, high-grade Ramp zone along strike and to depth, expand the Trap system, and drill a series of newly generated targets, including Tower and X.

Management and insiders own approximately 33.4 per cent of the outstanding shares of the company and, as a result, are fully aligned with shareholders.

We seek Safe Harbor.
