("Red Rock" or the "Company")

Joint Venture Provisional Award

1 June 2026

Red Rock Resources Plc, the natural resource exploration and development company with interests in gold, base metals, battery metals, and hydrocarbons, principally in Africa and Australia, announces the issue of the Avis de Non Objection (ANO) by the Direction Générale de Contrôle des Marchés Publics (DGCMP) of the Ministry of Budget of the Democratic Republic of Congo, to our joint venture partner in relation to the award of a contract for the provision and operation of factories for low cost housing.

This follows a process whereby the Company formed the 50-50 joint venture ("JV") in November 2024, made a proposal to and signed an agreement with the Ministry of Rural and Periurban Development in October 2025, and subsequently in 2026 the JV won an open tender which was then reviewed by the DGCMP and other regulatory bodies.

Previous announcements have been made by the Company as matters progressed, notably on 6 November 2024, 23 October 2025, 11 February 2026, and 1 April 2026.

The ANO reads in part:

"I have the honour to receive your letter………………..of 12th May 2026 by which you sent me, for Notice of No Objection, the evaluation report of the offers and the minutes of Provisional Award relating to the works of construction and installation of the factor[ies] for manufacture of wall panels for the rapid construction at least cost of houses, and thank you.

After checking your dossier, the DGCMP issues this Notice of No Objection on the said evaluation report and minutes making its Provisional Award to KOTO DRC sarl, at a cost of $21,476,663.10" [Translation from the original French]

Red Rock Chairman Andrew Bell comments: "The importance that the Government and the Ministry attach to this project is shown by the Ministry's decision to fast track it by funding the initial factories. Koto is now able to draw this money, and order the factories, the first of which is expected to arrive in late Summer or early Autumn. The JV expects to scale up operations rapidly, and make first sales of houses by year end.

Meanwhile the resolution of the Company's claims in relation to the Musonoi licence and the grant of the first major copper-cobalt licence since the loss of Musonoi are near the announcement stage.

After a long period of working on these three issues, their conclusion, or the conclusion of even this one of them, is a matter of the first importance for the Company. "

Other: The Company has been granted a 3 year renewal of its important Boulon gold licence in Burkina Faso, at a cost of XOF 7,000,000 and has progressed further in its renewal of its Kenya gold licences.

Notes:

(1) The Company has made this announcement because the full Avis d'Attribution Provisoire ("Provisional Award") may now at any time be posted on the website of the Autorité de Régulation des Marchés Publics where it will be publicly accessible, and it is desirable that the key element in that Décision, which is contained in the Avis already in our hands but without some fuller context, should be made available to all shareholders simultaneously;

(2) Koto DRC sarl is the Company's partner under the 50-50 JV signed in November 2024 which was formed as an unincorporated joint venture with the object of implementing a low cost housing project and operating mines granted in relation to the financing of that project, and an agreement to convert the unincorporated joint venture into joint venture limited companies upon concretisation of the project, a process that is now under way;

(3) The JV will assist the Ministry in the construction of the factories, each of which will have the capacity to produce between 3,300 and 5,000 houses a year, and will operate them on behalf of the Ministry and jointly sell the housing units;

(4) The Avis d'Attribution Définitive or Final Award notice follows submission of a timetable and is a compliance stage whereas the Avis d'Attribution Provisoire or Provisional Award is generally the substantive stage;

(5) The Company notes (a) that the operations of the JV Company are expected to be profitable but that it is unable to quantify profitability at this stage and (b) the establishment and initial operation of the three factories has been funded by the amounts allocated under the Provisional Award;

(6) As further information is released, it will be communicated to shareholders.
