Resolute Mining and Nimba Mining Gold Establish “Landaya Gold”, Their Joint Venture Dedicated to Gold in Guinea

Abidjan, 13 August 2026 – Resolute Mining Limited (“Resolute”) (ASX/LSE: RSG) and Nimba Mining Gold S.A. (“NMG”), an affiliate of Guinea’s state-owned mining group Nimba Mining Company S.A. (“NMC”), have jointly signed the Articles of Association of Landaya Gold SAS (“Landaya”), their joint venture established to advance the development of gold projects in the Republic of Guinea.

The Articles of Association were signed by Mr. Patrice L'Huillier, representing Nimba Mining Gold S.A., and Mr. Karl Akueson, Vice President – Growth of Resolute Mining Limited. The incorporation of the company is currently being finalised with the relevant authorities.

The signing formalises the Strategic Memorandum of Understanding (“MoU”) entered into by the two companies on 31 March 2026.

Landaya will be responsible for evaluating, exploring and, where appropriate, developing identified gold-bearing areas in Guinea, building on the preliminary assessment already conducted by the technical teams of both companies.

The establishment of Landaya forms part of NMC’s strategy to diversify beyond the bauxite sector, supported by the Government of Guinea and aligned with the Vision and Simandou 2040 Programme. It also supports Resolute’s growth strategy in established gold-producing jurisdictions across West Africa.

Landaya is 50% owned by Resolute Mining and 50% by Nimba Mining Gold, with its registered headquarters in Conakry, Guinea.

Mr. Patrice L'Huillier, Managing Director of Nimba Mining Company, said:

“With Landaya Gold, we are moving from intention to action. Following the signing of our Memorandum of Understanding, we are now establishing a joint legal vehicle capable of advancing major gold projects for Guinea.

This company is Guinean in its foundations and international in its standards. It will contribute to strengthening local content, developing talent and creating sustainable value for the State and local communities, in accordance with the guidelines of the Simandou 2040 Programme and the vision of the Ministry of Mines and Geology, the technical supervisory authority of NMC and NMG.”

Statement from Karl Akueson

Mr. Karl Akueson, Vice President – Growth of Resolute, said:

“The creation of Landaya Gold marks a significant milestone in our commitment to Guinea.

Building on our more than 30 years of history in West Africa, we will conduct this work according to the highest standards of safety and environmental responsibility, while ensuring value is shared with local communities and the State.”
