26 October 2026

Nativo Resources Plc

("Nativo" or the "Company")

Award of Detailed Design and Construction Engineering Contract

La Patona Gold Ore Processing Plant - detailed engineering phase commences with StratumX and Nativo's in-house team

Nativo Resources plc (LON: NTVO), the precious metals company with gold mining and processing interests in Peru, announces that the Company and its wholly owned Peruvian subsidiary, BOKU Resources S.A.C. ("BOKU"), have awarded the contract for the detailed design and construction engineering of the La Patona Gold Ore Processing Plant ("La Patona") to Stratumx CC S.A.C. ("StratumX"), a multidisciplinary consulting, engineering and project management firm, working alongside Nativo's in-house engineering team. Work has commenced.

Highlights

·    Detailed design and construction engineering contract for La Patona awarded to StratumX, in partnership with Nativo's in-house engineering team; work has started.

·    Converts the completed (Front-End Engineering Design) FEED and Basis of Design into the issued-for-construction engineering and procurement specifications needed to order equipment and build the plant.

·    Marks the transition from FEED into the Detailed Design / Engineering, Procurement, and Construction (EPC) stage of Nativo's phased build (Initial phase of 70 Tonnes Per Day (TPD) capacity, expanding to 110 TPD and 350 TPD).

·    Keeps La Patona on track for equipment and services ordering in Q4 2026, with first gold targeted in H1 2027; Phase 1 construction funding is secured via the non-dilutive gross revenue share arrangement with Chancery Royalty announced on 18 September 2026.

Stephen Birrell, CEO, commented:

"This award moves La Patona from design to the delivery stage. With FEED and the Basis of Design complete and Phase 1 funding secured, detailed design is the final engineering step before we order equipment and build. Combining StratumX's engineering capability with our in-house team gives us the rigour and pace to keep La Patona on track for FID and equipment ordering in Q4 2026 and first gold in 2027."

Elvis J. Mamani, General Manager of StratumX, commented:

"We are pleased to join Nativo and BOKU at the point where La Patona moves from design into delivery. Our mandate is to take the completed FEED and Basis of Design to issued-for-construction engineering and procurement specifications for Phase 1, on a master plot plan that allows the plant to scale to 350 TPD without rebuilding what is constructed first. Working alongside Nativo's in-house engineering team, our multidisciplinary group will apply the rigour and pace that a funded, schedule-driven project requires."
