Nativo Resources Plc

("Nativo" or the "Company")

Framework Agreement for Expanded Gold Mining Opportunities, Peru

Nativo Resources plc (LON: NTVO), the Peru-focused gold mining company, is pleased to announce it has entered into a framework agreement (the "Framework Agreement") with Constructora e Inversiones Andina Kuboc C&P SAC ("Kuboc") pursuant to which the parties intend to work together to identify, evaluate and, where approved by Nativo, develop new gold and other precious metals mining opportunities in Peru. Under the Framework Agreement, Kuboc will act as operator of any approved projects, with Nativo funding approved expenditure. Where a project proceeds to development, Nativo will hold a 75% interest and Kuboc a 25% interest in the project special purpose vehicle, subject to Nativo first recovering its invested capital. Nativo will have a pre-cost recovery "waterfall" where the profit share is 85% : 15% in favour of Nativo until full cost recovery.

Founded in 2019, Kuboc is an experienced Peruvian mining services provider currently operating two mines. It has expertise in non-ferrous metals (including gold) as well as transport and construction in the mining sector. Kuboc is authorised by the Peruvian Ministry of Energy and Mines (MINEM) for exploration, exploitation, development and beneficiation of minerals.

The parties have initially identified a short list of gold, silver and copper exploration opportunities, across the Ayacucho, La Libertad, Arequipa and Ancash regions at varying stages of development.

Nativo's initial exposure to review the identified projects is not expected to exceed US$70,000.

Stephen Birrell, Chief Executive Officer of Nativo, commented:

"This agreement creates a framework through which we can pursue additional opportunities in partnership with an established mining contractor in-country with a strong operational track record. The criteria for project selection will be based on projects being commercially rewarding and able to be in production within 12 months, i.e. effectively being shovel ready. As we continue executing our strategy in Peru by progressing towards initial ore sales, advancing our processing capabilities and evaluating our concession portfolio, we believe having a trusted local operating partner strengthens our ability to identify, assess and efficiently advance future growth opportunities."
