Leviathan Metals Provides Update On Its Diamond Drilling Program At Central Project Kalahari Copper Belt Botswana
Leviathan Metals Corp. had completed fourteen mostly widely-spaced diamond drill holes at Central for approximately 3,600 metres of drilling, with the D’Kar-Ngwako Pan Formation contact – i.e. target KCB stratigraphy - in evidence in all but two of the holes drilled. Copper sulphides were observed in eight holes. Core cutting, sampling and laboratory analysis are ongoing, assay results pending. Domal structure was confirmed, north-western limb demonstrates marked veining, brecciation and alteration and is regarded as a key structural target for mineralization. Drilling had also confirmed the presence of the domal structure at Central previously identified by Leviathan’s geological team in ground magnetic and Airborne EM datasets. This structure has a gently dipping south-eastern limb, a more steeply dipping north-western limb, and structural “nose”. The steeper dip of the north-western limb, in combination with sedimentary facies variations also recorded by Leviathan’s team, appear to be affected by a greater degree of structure, veining, brecciation and alteration - and as such may host pathways and trap sites for potential mineralizing fluids. Notwithstanding its emergence as a prospective target area, the north-western limb accounts for only 50% of drilling meterage to date. Drilling at Central had readily confirmed target KCB stratigraphy in practically every hole drilled, with copper sulphide minerals observed in the majority of cases. The presence of the Hyena Hills dome was confirmed, with the deformed north-western limb showing as a particularly favourable target structure. Leviathan Metals Corp. had hit the DKF–NPF contact in almost every hole, seen visual copper sulphides in the majority of holes, and demonstrated the presence of a previously untested domal structure on Central, all in the opening stages of the program. Copper sulphide minerals - in the form of chalcopyrite, in some cases accompanied by bornite and/or chalcocite - were observed in eight holes where they occur in minor amounts, over intervals of up to 10 metres or more. Galena, a lead sulphide mineral is also observed in the drill core: seen to form ‘haloes’ peripheral to copper mineralization elsewhere on the KCB this may be a favourable proximity indicator. Visual observations are indicative in nature. Following completion of the initial drill holes and receipt of sample analyses, step-out drilling will target zones of greatest interest. In the meantime, further holes are planned and in progress on the “nose” area and on both of the limbs. All such drilling works fall within the drilling program announced by Leviathan on June 2, 2026, which remains ongoing. All drillholes encountered Kalahari overburden (mostly sand) from surface to a depth of approximately 70-80 metres. Drilling has been designed to target potential sediment-hosted copper mineralization of the style and magnitude observed at MMG Limited’s adjoining Khoemacau property, specifically at the DKF-NPF contact, in an area where this contact is folded into a very clear and prominent large domal structure - the ‘Hyena Hills dome’. Over 20 kilometers of this prospective contact has been interpreted at Central from airborne electromagnetic survey data, as well as from high resolution ground magnetic surveys completed at the property in 2023-2024. Initial drillholes were been positioned to locate the DKF-NPF contact with precision. Drilling works are being performed by Mitchell Drilling International using a Sandvik DE710 diamond rig. Mitchell draws on fifty-seven years of drilling experience globally and in Africa, including almost twenty years of drilling under similar conditions within the KCB in Botswana. To date, no drill holes have been lost in the current program. Visual observations are preliminary, and laboratory assays are required to determine copper grades and potential mineralized interval widths. Core cutting, sampling and laboratory analysis are ongoing; core yard operations are shown. Assay results are expected in due course and may assist targeting and guide subsequent step-out drilling across the most prospective areas of the Central Dome. A portable XRF analyser is now in use and will support rapid multi-element geochemical screening of drill core, assisting with lithological correlation, alteration mapping and drill targeting while laboratory assays are pending. Collar positions of the holes drilled to date are given as WGS 84 UTM - zone 34S. The Central Project, which directly adjoins MMG’s Khoemacau group of deposits and discoveries (combined Measured and Indicated Mineral Resources of 94Mt @1.8% Cu and 22 g/t Ag and Inferred Mineral Resources of 188Mt @1.6% Cu and 20 g/t Ag) on the KCB which, together with the nearby Banana Zone, Zone 6 and Ophion (combined Measured and Indicated Mineral Resources of 33Mt @1.4% Cu and 21 g/t Ag and Inferred Mineral Resources of 141Mt @0.9% Cu and 10 g/t Ag) were acquired by MMG Ltd. in 2023 for USD 1,900 million. Leviathan and its qualified person have been unable to independently verify the information in respect of MMG’s Khoemacau group of deposits and the mineralization hosted on the Khoemacau deposits is not necessarily indicative of mineralization on Leviathan’s Project. Central displays similar large-scale geological characteristics to those observed at Khoemacau, making the property prospective for a Tier 1 copper discovery. Specifically, all known KCB copper deposits – including those of Khoemacau – occur at or close to a well-understood stratigraphic contact (namely the interface between the D’Kar and Ngwako Pan Formations) on the flanks or hinges of kilometer-scale antiforms or “domes”, typically within secondary folds, shears or other structural trap-sites which focused the mineralizing fluids. The Project boasts over 20 kilometers of this contact, mostly around the main domal structure referred to as the Hyena Hills dome, as supported by recent airborne electromagnetic data, as well as high resolution ground magnetic data collected in 2023 and 2024. The Hyena Hills dome is the next dome south from those hosting the Khoemacau deposits and discoveries (including Zone 5 and Zone 9); each of the other domes at Khoemacau hosts at least two copper deposits or discoveries. The Project area is almost entirely ‘blanketed’ by a cover of poorly consolidated Kalahari sediments, exploration through this cover relying on a combination of geophysical methods and drilling. AEM data are commonly used to map and model a conductive marker unit, typically found approximately 100-200 meters above the DKF-NPF contact. Interpretations of this marker are used to increase confidence in the location of the DKF-NPF contact and in the identification of structures affecting it, which are considered important controls on mineralization.
