Mineralization at Campo Morado mine consists of polymetallic volcanogenic massive sulphide deposits hosted within an upper Jurassic to lower Cretaceous sequence of felsic to intermediate flows, tuffs and fragmental volcanic rocks, and fine-grained sedimentary rocks. There is strong geological continuity of the mineralization as demonstrated in the extensive diamond drilling and underground development.

During Campo Morado’s last full production year of 2014 only zinc and copper concentrates were recovered using room and pillar mining methods, Telson is planning to restart mining operations employing block caving mining methods to potentially reduce mining costs with an emphasis on maximizing recoveries of all economic metals including gold, silver, zinc, lead and copper. Additionally, Telson is planning to focus mining activities to zones outlined within the defined resources where higher precious metal content is available.
