Kaoko Metals Limited has begun its maiden diamond drilling program at the Chalkos Copper-Silver Project in Namibia. The campaign involves 2,000 to 3,000 metres of drilling focused on the Donkey Hill and Otniel prospects, where the company aims to test surface-exposed mineralisation at depth and assess structural controls.

Drilling contractor Optimine Exploration mobilised to the site on 3 August 2026. Alongside the drilling, the company is conducting a structural mapping program across a 2.2-kilometre corridor connecting the two prospects. This work is designed to help refine the geological model and guide future exploration efforts.

“The start of drilling at Chalkos represents a defining milestone for Kaoko Metals and follows months of systematic exploration and target generation.”

“Importantly, this program is only the beginning of our journey. The drilling will provide invaluable geological and structural information that will enhance our understanding of the broader mineralised system and help unlock the considerable exploration potential across the Chalkos Project.”

— Gerard O'Donovan, Managing Director

Kaoko Metals operates with a dual-project strategy in Namibia, balancing this copper-silver focus with resource definition at its Karibib Gold-Copper-Tungsten Project in the Damara Belt. The company maintains a preference for the systematic advancement of early-stage assets through modern exploration techniques, with the current data from Chalkos set to be integrated into an evolving geological model to inform upcoming exploration activities.
