Leviathan Metals Enters into Purchase Agreement to Acquire Key Strategic Kalahari Copper Belt Landholding, Botswana

• Target Prospecting License adds over 10 kilometers of interpreted D’Kar-Ngwako Pan Formation contact, and thereby prospective target structure and stratigraphy, to the Central portfolio.

• Covers 270 square kilometers, in close proximity to the Central portfolio expanding its total area to 590 square kilometers, exclusive of Leviathan’s other Kalahari Copper Belt holdings.

• Further cements Leviathan’s presence in this prospective yet highly underexplored southern KCB target zone.

Vancouver, British Columbia–(Newsfile Corp. – March 19, 2026) – Leviathan Metals Corp. (TSXV: LVX) (OTCQB: LVXFF) (FSE: 0GP) (“Leviathan“, the “Company“) is pleased to announce it has entered into a Purchase Agreement (the “Agreement“) with a private third party (the “Vendor“) in respect to a Prospecting License (the “License“), situated in close proximity to its 100%-owned Central Project (“Central“, the “Project“), on the Kalahari Copper Belt (the “KCB“), Botswana.

The License covers approximately 270 square kilometers, expanding the Project to a total area of 590 square kilometers¹. This strategic acquisition adds a further ten kilometers of interpreted D’Kar-Ngwako Pan Formation contact – and thus key target structure and stratigraphy – to Leviathan’s Central portfolio, in the near vicinity of MMG’s Khoemacau group of deposits and discoveries.

Under the terms of the Agreement, Leviathan will acquire a 100% interest in the License by (i) paying the Vendor the sum of US$ 200,000 in cash upon the renewal and initiation of ownership transfer (the “Transfer“) of the License in favour of Innovation Surveyors (Pty) Ltd. (“Innovation“) , a wholly-owned subsidiary of Leviathan, (ii) payment to the Vendor the sum of US$ 300,000 in cash, and issuance of 991,666 common shares in the Company upon fulfilment of closing conditions, including the approval of the Transfer by the relevant authorities in Botswana and the approval of the TSX Venture Exchange of the transactions contemplated by the Agreement (together, “Closing“), and (iii) grant in favour of the Vendor a 1.0% net smelter royalty in respect of the License., (which can be purchased and cancelled by Levithan for US$ 1,500,000).

About the Central Project

The Central Project, now totalling 590 square kilometers 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 Ag²,³) 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 US$1.9 billion (the “Adjacent Properties“).

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.

With the additional ground Central will boast over 30 kilometers of this contact, mostly around the main domal structure referred to as the Hyena Hills dome, as supported by 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; each of the other domes at Khoemacau hosts at least two copper deposits or discoveries.

Botswana is a politically stable pro-mining investment jurisdiction – ranked #2 in Africa by the Fraser Institute (2024), enjoying investor-friendly legislation, a highly proficient and well-educated workforce, and first world infrastructure – set up to support mining, which is a pivotal and widely-accepted national economic driver. The Kalahari Copper Belt is regarded by the USGS as one of the world’s most prospective areas for sediment-hosted copper deposits.
