Leviathan Metals has reported copper grades of up to 0.47% from its initial diamond drilling results at the Central Project in Botswana’s Kalahari Copper Belt, where more than 7,000 metres of drilling have been completed across 26 holes.
The Canadian-listed company announced on 10 November 2026 that laboratory results from six drillholes had identified copper and silver mineralisation within a geological corridor extending more than four kilometres.
The strongest copper intersection was recorded in hole CEN_DD_017, which returned 1.29 metres grading 0.47% copper and 11.9 grams per tonne silver from a depth of 142.9 metres.
Another hole, CEN_DD_016, intersected approximately 1.06 metres grading 0.22% copper and 10.91 grams per tonne silver from 116.8 metres.
Hole CEN_DD_003 returned 2.3 metres grading 0.15% copper from 228 metres, while CEN_DD_009 intersected one metre grading 0.10% copper and five grams per tonne silver from 162 metres.
The company said the results were consistent with the margins of a potentially broader copper mineralisation system rather than its highest-grade portions.
Leviathan reported a relationship between copper mineralisation and geological structures, including folding, shearing, brecciation and faulting, which can create pathways for mineral-bearing fluids.
Lead and zinc mineralisation identified near the copper intersections is also being used to guide exploration towards potentially stronger copper zones.
The company said visual copper sulphide mineralisation had been observed in all but two of the 26 drillholes completed so far.
However, laboratory assay results have been received only for selected intervals from six holes, meaning the broader extent and grade of the mineralisation remain unconfirmed.
The Central Project covers more than 20 kilometres of the geological contact between the D’Kar and Ngwako Pan formations, which hosts copper deposits elsewhere in the Kalahari Copper Belt.
Much of this geological contact surrounds the Hyena Hills Dome, a large folded structure identified through geophysical surveys and subsequently supported by drilling.
Leviathan said significant sections of the prospective geological contact remained sparsely explored, with drillholes spaced as far as two kilometres apart in some areas.
The company is using geological observations, laboratory results and portable X-ray fluorescence readings to identify additional drilling targets.
Leviathan chief operating officer Jeremy Crozier said the initial results provided evidence of a broader mineralising system.
“Initial results from shallow drilling at Central appear consistent with the margins of a broader mineralizing system. Practically every hole displays evidence of mineralization, and our geological work shows a clear relationship between copper mineralization and progressively increasing shearing, brecciation and faulting (which serve to ‘prepare’ the rocks for fluid passage), as well as lead and zinc ‘halo’ mineralization, providing us with strong vectors for continuing drilling.”
Crozier added that significant areas of the project remained lightly explored.
“Beyond these vectored targets, significant areas of Central remain very thinly tested”.
The company said delays in laboratory quality-control procedures had slowed the release of assay results, but further results were expected shortly.
Leviathan’s wholly owned Central Project directly adjoins MMG’s Khoemacau copper deposits and discoveries in Botswana.
According to Leviathan’s announcement, the adjoining Khoemacau group has combined measured and indicated mineral resources of 94 million tonnes grading 1.8% copper and 22 grams per tonne silver, alongside inferred resources of 188 million tonnes grading 1.6% copper and 20 grams per tonne silver.
The company said Central shares several geological characteristics with Khoemacau, particularly the presence of favourable sedimentary formations and large folded structures associated with copper mineralisation.
However, Leviathan cautioned that it had not independently verified the Khoemacau resource information and that mineralisation at the neighbouring deposits did not necessarily indicate similar grades or quantities at Central.
The initial Central drilling results establish the presence of copper mineralisation but do not constitute a mineral resource estimate.
Leviathan will continue drilling to investigate whether the geological structures and associated metal concentrations lead to larger or higher-grade copper zones.
