LEVIATHAN METALS RECEIVES INITIAL ASSAY RESULTS FROM ITS DIAMOND DRILLING PROGRAM AT THE CENTRAL PROJECT, KALAHARI COPPER BELT, BOTSWANA

Leviathan Metals Corp. has received initial assay results from its diamond drilling program at the company's 100-per-cent-owned Central project, Kalahari copper belt (KCB), Botswana.

Results have been received for targeted horizons within six holes, and include 2.3 metres (m) at 0.15 per cent copper (Cu) from 228 m in hole CEN-DD-003 (1), 1.0 m at 0.1 per cent Cu and five grams per tonne (g/t) silver (Ag) from 162 m in hole CEN-DD-009, 1.06 m at 0.2 per cent Cu and 10.91 g/t Ag from 116.8 m in hole CEN-DD-016, and 1.29 m at 0.47 per cent Cu and 11.9 g/t Ag from 142.9 m in hole CEN-DD-017.

These results, when taken in the context of their host lithology and structure, are considered to represent the margins of a broader mineralizing system within Central. At known deposits elsewhere on the KCB, peak intersections in excess of 0.1 per cent Cu per drill hole each occur within the mineralized envelopes of their respective deposits (2). Lead and zinc are also known to associate with KCB-style mineralization in a proximal manner and as such the anomalous manifestations of these two metals in the reported intervals are considered a favourable zoning indicator (see table 1).

At Central, the reported results fall within a geological envelope measuring in excess of four kilometres (km) in length. This envelope is concordant with interbedded siltstones and sandstones close to the so called D'Kar-Ngwako Pan formation (DKF-NPF) contact -- target KCB stratigraphy -- in combination with folding, shearing, brecciation and faulting each of styles typical of other KCB deposits that together appear to serve to concentrate mineralizing fluids.

All but two drill holes from the Central program to date display visual copper sulphide mineralization, all yield pXRF copper readings, almost every hole has encountered the DKF-NPF contact and the domal structure previously inferred to exist on the basis of geophysical data prior to drilling is robustly reflected in Leviathan's drilling data.

Leviathan chief operations officer Jeremy Crozier remarked: "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. More simply put, there are more indicators present than simply copper itself and, together, these demonstrate the presence of a mineralizing system.

"Beyond these vectored targets, significant areas of Central remain very thinly tested."

A number of so-called vectors -- or directional targeting factors -- are being developed from Leviathan's drilling data set and are being used to guide continuing drilling. At the time of writing, slightly over 7,000 metres of drilling have been completed at Central across 26 holes (table 2). Further results will be reported once in hand. Significant portions of the interpreted DKF-NPF contact at the project have only been tested at a very broad drill pattern and in places at a spacing of up to two kilometres.

Delays due to the analytical performance of certified reference materials inserted into the sample flow for QA/QC (quality assurance/quality control) purposes have slowed Leviathan's ability to report results. The company is actively addressing this matter and expects to report further results shortly.

About the Central project

The Central project, which directly adjoins MMG's Khoemacau group of deposits and discoveries (combined measured and indicated mineral resources of 94 million tonnes (t) at 1.8 per cent Cu and 22 g/t Ag, and inferred mineral resources of 188 million t at 1.6 per cent Cu and 20 g/t Ag (3) (4)) on the KCB, which, together with the nearby Banana zone, zone 6 and Ophion (combined measured and indicated mineral resources of 33 million t a 1.4 per cent Cu and 21 g/t Ag, and inferred mineral resources of 141 million t at 0.9 per cent Cu and 10 g/t Ag), were acquired by MMG Ltd. in 2023 for $1.9-billion (U.S.). 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 kilometre-scale antiforms or domes, typically within secondary folds, shears or other structural trap sites that focused the mineralizing fluids.

The project boasts over 20 kilometres 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 to 200 metres 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.

Copper sulphide minerals -- in the form of chalcopyrite, in some cases accompanied by bornite and/or chalcocite -- have been observed in almost all holes, 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.

Botswana is a politically stable pro-mining investment jurisdiction -- ranked No. 2 in Africa by the Fraser Institute (2024), enjoying investor-friendly legislation, a highly proficient and well-educated work force, and first world infrastructure -- set up to support mining, which is a pivotal and widely accepted national economic driver. The KCB is regarded by the USGS as one of the world's most prospective areas for sediment-hosted copper deposits.

Qualified person and data verification

Graham Norton (PrSciNat), a qualified person under National Instrument 43-101, Standards of Disclosure for Mineral Projects, has approved the scientific and technical information contained in this news release relating to the Central project. Mr. Norton is a consultant for Leviathan and has observed the drill core and drilling information gathered to date.

Neither the qualified person nor Leviathan has verified the scientific, technical or other information disclosed in respect of the adjacent properties.

Drilling was carried out by independent contractor, Mitchell Drilling International, using a Sandvik DE710 diamond rig. Drill holes were collared using PCD then PQ drilling methods into fresh rock, then completed using HQ-size tooling. Average core recovery for the program to date is 99 per cent. Drill core was cut in half by the site team using a rock saw, with one-half of the core then taken as a sample for analysis. Sample intervals were generally between 30 and 150 centimetres (cm) (average of 93 cm) producing samples of between one and five kilograms (kg). Samples were delivered to the independent SGS geochemistry laboratory facilities in Randfontein, South Africa. The samples were dried, crushed and pulverized using method codes DRY105, CRU75 and PUL85-CR, respectively, then underwent multielement determination by four-acid digest with ICP-OES (inductively coupled plasma optical emission spectroscopy) finish (method code ICP40Q12). Copper overlimits were analyzed using an appropriate method. Leviathan routinely inserted multielement geochemical standards, blanks, field and laboratory duplicates samples into the drill core sample stream as part of a documented quality assurance/quality control (QA/QC) process to monitor laboratory performance. Leviathan inserted QA/QC material at a rate of four certified standards, four quartz blanks, and four field or laboratory duplicates per every 100 samples; averaging 12 per cent of the sample stream. QA/QC sample results, in copper mineralization, which did not pass Leviathans QA/QC controls were reassayed at an interval of 10 samples before and after the failed QA/QC sample, until the results passed Leviathan's QA/QC controls.
