About the Kalahari Copper Belt

The 800-kilometer-long Kalahari Copper Belt hosts significant Cu-Ag deposits of the Sediment-Hosted Stratiform Copper type, and is regarded by the USGS “as one of the world’s most prospective areas for yet-to-be-discovered sediment-hosted copper deposits”.

Most KCB discoveries have been made within the last 25 years, and the largest deposits within the last 15 years. The KCB’s proven Cu-Ag potential, coupled with simple, reliable and transparent regulation, ready infrastructure, and a skilled workforce make it a makes it a highly attractive region for exploration.

Much of the KCB is covered by young overburden of the Kalahari Group sands, which conceals the target geological structures and formations. Using modern geophysical and geochemical methods, new copper deposits may be identified within this highly underexplored district, and it is for this reason that most KCB deposits have been found relatively recently.

Most known KCB Cu-Ag deposits are located at or near a well-understood stratigraphic boundary, specifically that between Ngwako Pan Formation and the overlying D’Kar Formation, or more simply the “DKF-NPF contact”, itself a so-called “redox” boundary. Deposits form in favourable structural sites such as fold hinges, parasitic folds, shears and thrusts, considered important in channeling and constraining fluid flow, and in trapping the fluids. Copper mineralization is present in sulphide forms, including chalcopyrite, bornite and chalcocite, and can attain thicknesses of tens of meters, extending hundreds of meters along strike and dip.

As their name implies, Sediment-Hosted Stratiform Copper deposits are hosted by sedimentary formations, and these generally exhibit lateral continuity even if folded. In the case of the KCB, these host formations display distinctive magnetic and electromagnetic (EM) signatures, and as such magnetic and EM surveys are of importance in interpreting “DKF-NPF contact” and the folds, shears and hinges that may affect it, to define drill targets.

About Leviathan’s Central Project

Leviathan’s 100% owned Central Project directly adjoins MMG’s Khoemacau property, and encompasses the southern end of a NW-SE corridor that MMG have referred to as the "Zone 5 Corridor”. This corridor hosts the largest and highest-grade known copper deposits within the KCB, mostly on the flanks of very large anticlinal folds, also referred to as domes. The interpreted dome at the Central Project (the “Hyena Hills” dome) represents the next dome south on the Zone 5 Corridor and is the only one that has received little in the way of exploration, there having been no exploration drilling on the Central Project. The Central Project is interpreted to host approximately 24 km of the DKF-NPF contact, mostly on the limbs and around the hinge of the Hyena Hills dome, as supported by high-resolution ground magnetic survey completed between 2023 and 2025. A portion of the DKF-NPF on the Central Project is on the limb of the so-called Mowana fold, on which MMG’s Zone 9 discovery is situated (12 kilometers along strike).

An airborne electromagnetic (AEM) survey both of this dome and the continuation of the Mowana fold limb will be flown shortly, from which it is expected that a series of drilling targets will be developed. Like MMG’s ground, the Central Project is covered by a cover of Kalahari overburden, hence the importance of quality geophysical data.
