The Project is located along the eastern margin of the KCB, a continental-scale geological feature stretching in a Southwest-Northeast direction across Namibia and Botswana hosting sedimentary copper-silver deposits. Copper-silver mineralisation typically occurs along the contact between the D’Kar Formation, which is mostly made up of reduced siltstones, and the Ngwako Pan Formation, which consists mainly of oxidised sandstones. The contact is repeated across strike at the favour of isoclinal folds. The position of copper-silver mineralisation is controlled by the lithology and oxidation state contrast along the contact, as well as the presence of folds and associated structures.

The KCB is home to the low-cost Khoemacau copper-silver mine which started production in June 2021. The mine has a full rate production rate of ca. 60ktpa Cu and ca. 1.6Mozpa Ag, extracted from ore from the Zone 5 underground mining operation, which is located about 25 km from the Tenement.

The Tenement is located next to Galileo Resources licence PL039/2018 and near ARC Minerals licence PL135/2017 (Virgo Copper-Silver Project), where a 3km long soil anomaly associated to the D’Kar / Ngwako Pan formations contact has been recently identified.

Recent interpretation of regional airborne magnetic data shows that a ca. 10km long stretch of the contact between the D’Kar and Ngwako Pan formations contact is passing through the northern part of the Tenement, along the eastern margin of a fold structure, which makes it a perfect setting for copper-silver mineralisation
