About the Anzá Project

Anzá is a gold exploration project, comprising granted exploration licences and applications for exploration licences in the prolific Mid-Cauca belt of Colombia.

The Anzá Project has been the subject of an Exploration Agreement with Venture Option ("Exploration Agreement") with Minera Monte Águila S.A.S. ("MMA"). MMA is itself a 50/50 joint venture between Newmont Corporation ("Newmont") and Agnico Eagle Mines Limited ("Agnico"). MMA is the current operator of the Anzá Project.

The Anzá Project is located 50km west of Medellin and is easily accessible by all-weather roads and boasts excellent infrastructure including water, power, communications as well as a large exploration camp.

Since the Company acquired the Anzá Project in December 2014, almost 48,000m of drilling has been undertaken, mostly on the central APTA prospect where a high-grade body of gold mineralisation had been discovered. The most recent drilling activities were at Pepas in the north of the Anzá Project areas where three holes returned excellent results, the best being 150.9m @ 3g/t Au from surface (hole PEP001, announced on September 6, 2022). On reassuming operatorship of the Anzá Project, the Company's initial focus will be on the Pepas discovery.
