Galileo Resources Plc

("Galileo" or the "Company")

Conditional Sale of 2 Kalahari Copper Belt Licences for US$3 million

to Sandfire Resources Limited group

Galileo Resources plc ("Galileo" or the "Company") is pleased to announce that on 15 June 2026 it entered into a conditional share purchase agreement with Metal Capital Exploration Limited ("Metal Capital"), a wholly owned subsidiary of ASX-listed Sandfire Resources Limited (Sandfire), with Sandfire acting as purchaser guarantor.

The agreement relates to the conditional sale of its wholly owned subsidiary Virgo Business Solutions (Pty) Ltd ("Virgo"), which owns Botswana prospecting licences PL039/2018 and PL040/2018 (the, "Prospecting Licences") (the "Agreement").

The Agreement provides for an aggregate upfront consideration of US$3 million payable on completion, together with a potential one-off success payment of between US$20 million and up to US$80 million ("Success Payment"), subject to meeting nominated thresholds for contained copper  in a First Qualifying Ore Reserve under the terms of the Agreement.

Under the Agreement:

·    Metal Capital has made an exploration commitment of US$4.5 million on the Prospecting Licences (the "Exploration Commitment") within three years of completion (the "Exploration Period"), with US$2.25 million of that amount of the Exploration Commitment to be spent within 18 months of completion and US$2.7 million of that amount of the Exploration Commitment is to be spent on drilling and assaying.  Metal Capital has committed, subject to necessary approvals, permits and consents to complete at least 4,000 metres of drilling on the Prospecting Licences by 31 December 2026.

·    A one-off Success Payment is payable to the Company if the first qualifying ore reserve reported under JORC Code 2012 edition, as amended or replaced from time to time ("JORC") on the Prospecting Licences contains at least 400,000 tonnes of contained copper (the "First Qualifying Ore Reserve").  

Colin Bird Chairman commented

"Metal Capital is a wholly owned subsidiary of Sandfire, with whom Galileo has an existing relationship in Botswana. From Galileo's point of view the transaction makes strategic sense as our highly prospective portfolio and our people resources are primarily located in Zambia and Zimbabwe, so we are better equipped to focus on and advance projects there. The structure of the transaction provides for consideration now and a significant future success payment if our belief in the potential of the Prospecting Licences is realised.  We look forward to Metal Capital progressing the agreed Exploration Commitment and wish them every success in this regard."

Overview of transaction with Metal Capital and Sandfire 

Upon completion under the Agreement, the Company will receive aggregate upfront cash consideration of US$3.0 million, which it intends to apply towards investment in the Company's principal projects in Zambia and Zimbabwe, with the prospect of a significant Success Payment if a First Qualifying Ore Reserve containing at least 400,000 tonnes of contained copper is declared, subject to the terms of the Agreement. The Board advises shareholders that the Success Payment is dependent upon the success of future exploration and therefore is not guaranteed as the Prospecting Licences have no defined Mineral Resource estimate.  As previously announced on 26 January 2021 , the Company has a similar Success Payment arrangement in relation to prospecting licences sold to Sandfire in 2021.

Further Information on Assets being sold

On 21 May 2020 the Company acquired Crocus-Serv Resources Pty Ltd, which owns PL253/2018 and is not being sold, and Virgo for £173,848.  Since then, the Company has undertaken exploration work on the Prospecting Licences which is summarised in the Company's group accounts to 31 March 2025, the group carrying value was £1.19m, made up principally of intangible assets held at the parent company level. Virgo had an attributable loss of £117K for the year ended 31 March 2025.  Subject to completion, the Company expects to record a profit on the disposal of Virgo and this will be reported in the audited accounts for the year ended 31 March 2027.

Technical Glossary:

An 'Ore Reserve' is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.

A 'Mineral Resource' is a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade (or quality), and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade (or quality), continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
