PERCUSSION DRILLING PROGRAM UNDER WAY AT LEVIATHAN METALS' SERULE AND FOLEY URANIUM PROJECTS, BOTSWANA

Leviathan Metals Corp. has arranged a combined reverse circulation (RC) and open-hole percussion drilling program of up to 2,500 metres is under way at its 100-per-cent-owned Serule and Foley projects, in the Central district of eastern Botswana.

• A shallow RC and open-hole percussion drilling program of up to 2,500 metres has commenced;
• Program designed to target the continuation of westward-dipping mineralization observed at the adjoining Letlhakane property;
• Historic assays from a 2024 RC drilling program at Serule returned between 196 and 1,247 ppm (parts per million) U3O8 (triuranium octoxide).

Drilling at Serule has been designed to target the continuation of westward-dipping mineralization observed at Australian Securities Exchange-listed Lotus Resources Ltd.'s adjoining Letlhakane property, at which indicated mineral resources of 71.6 Mt (million tonnes) at 360 ppm (parts per million) U3O8 (containing 56.8 Mlb (million pounds)) and inferred mineral resources of 70.6 Mt at 366 ppm U3O8 (containing 56.9 Mlb) have been reported. A north-south fence of eight RC drill holes completed at Serule in 2024 by the former property owner a short distance west of the shared Letlhakane property boundary intersected gently westward-dipping mineralized shale layers, forming a four-kilometre-wide zone at depths of between 65 and 130 metres. Intervals from the 2024 program range between two and 10 metres in thickness, and the grades based on laboratory analyses are between 196 and 1,247 ppm U3O8; the thickest interval (10 metres) has a grade of 415 ppm U3O8.

Leviathan chief operations officer Jeremy Crozier remarked: "We are pleased to have commenced drilling of our Botswana uranium portfolio with the objective of demonstrating the potential of Serule to host further Letlhakane-type mineralization. Drilling works completed in 2024 by the former owner confirmed the continuation of such mineralization onto Serule; we will now seek to build on this further westwards through a simple low-cost program. Serule is very well served indeed in respect to road, rail and power infrastructure making exploration work at the property straightforward, and casting a favourable light on potential future property development.

"Drilling at the company's Central project on the KCB is ongoing and we are excited to be drilling two excellent targets simultaneously. Our work at Serule and Foley is aimed at harnessing further opportunity in a timely manner."

Drill testing for possible extensions to mineralization to the southern flank of Letlhakane at the Letse target is also being undertaken, as is first-pass drilling at the Foley project, which lies 25 kilometres north of the Serule in a comparable geological setting at which surface radiometric anomalism was identified by the former property owner in 2024.

Drilling works are being performed by Gesondheid Pty. Ltd. trading as Rotsdrill Exploration using a Super Rock 5000 Drill Rig. Rotsdrill draw on extensive experience in Botswana -- including Letlhakane -- gained over more than a decade of operations. Wireline logging comprising gamma logging and other techniques will be performed by Digital Borehole Surveying Botswana Pty. Ltd. of Midrand, South Africa, upon completion of drilling.

Diamond drilling and geological interpretation at the company's Central project on the Kalahari copper belt is continuing, with market updates expected in the coming days. Slightly over 6,000 metres of diamond coring have now been completed; assays remain outstanding and will be reported once received.

About the Serule and Foley projects

The Serule project adjoins the Letlhakane uranium project -- owned by ASX-listed Lotus Resources Ltd. to its west. Letlhakane is hosted within gently dipping tabular layers within the lower Karoo Mea Arkose formation at depths of less than five m to over 100 m in the west, within a broad paleochannel that had a westerly flow. Work to date shows that the mineralized layers at Letlhakane extend downstream onto the Serule project at depths of between 65 and 130 metres based on a single line of eight RC holes drilled in 2024 by Afri-Uranium.

These RC holes were spaced 530 and 830 metres apart, and all except those and the northern and southern ends of the line intersected uranium mineralization, interpreted to be within one or two gently dipping layers in each hole,

Another area on the Serule project that is of interest is the Letse target, which appears to be the upstream SE extension of one of the subsidiary channels of the Letlhakane deposit. The historic drilling in this area intersected low-grade mineralization (100 to 220 ppm U3O8) in one to five m thick layers at depths of 13 to 45 m below surface.

The uranium-bearing intervals intersected in the RC drill holes completed at Serule in 2024 are hosted within beds of grey-coloured siltstones and shales of the Mea Arkose formation, presumably controlled by the reducing nature of these rocks. It seems probable that the mineralization in these holes is of the syn-sedimentary humate type as described at Letlhakane (Brough, et al. 20132), in which case the uranium was deposited during or shortly after emplacement of these sediments. Pyrite and organic material are present and are likely to have acted as reducing agents, important for uranium precipitation. At Serule, mineralization occurs within one or two layers, typically between one and 15 metres in thickness.

Geology

The projects lie on the eastern margin of the Kalahari Karoo basin, where the lower Groups of the Carboniferous to Jurassic-aged sedimentary rocks of the Karoo Supergroup are found and which rest unconformably on the Archean basement rocks. The Karoo supergroup is the most extensive stratigraphic unit in southern Africa, deposited in a series of vast retro-arc basins that formed behind the Cape Fold Mountain range commencing at around 330 Ma.

The formations present within the projects are those of the Ecca and Beaufort groups. The host of the uranium mineralization is the Mea Arkose formation, consisting of interbedded sandstones with subordinate mudstones, coal and conglomerate beds, deposited within an open west-flowing paleochannel, possibly at the eastern margin of the larger sedimentary basin.

The general dip of the Karoo within the area of the projects is gently to the southwest and west. Regionally, the area is affected by a series of northwest-southeast-striking faults, which are reported to have a strike-slip component (Brough et al., 2013). The uppermost unit in the area is the Kalahari Group, which is tertiary to quaternary in age, consists of sand and sandy soils up to 4.5 m thick, and is poorly developed within the area of the projects. Uranium mineralization at Serule is hosted within beds of grey-coloured siltstones and shales of the Mea Arkose formation, probably of what is termed "syn-sedimentary humate type" mineralization, as described at Letlhakane. At Serule, mineralization occurs within one or two very gently-dipping layers, typically between one and 15 metres in thickness, and extending approximately four kilometres laterally (north-south), presumed to reflect a broad paleo drainage. The stratigraphy and mineralization dip towards the south on this section, within an overall westward sloping drainage.

The target deposit types at the projects are the Basal Channel or Tabular subtypes of the sandstone-hosted uranium deposit class. Sandstone-hosted uranium deposits occur in carbon and/or pyrite-bearing fluvial (or less frequently marine) arkosic, medium-to-coarse-grained sandstones that contain, are interbedded with, and are typically bounded -- partially or fully -- by less permeable horizons. Uranium derived from U-rich source rocks passes through sandstone in groundwater flow and is precipitated from solution under reducing conditions, as triggered by the presence of a variety of reducing agents. In the case of Serule, pyrite and organic material are present, and are the likely reducing agents.
