Operations Update: Gold Ore Processing Plant

Update re Santa Cruz Sur, Argentina

Procurement and contracting underway at La Patona Gold Ore Processing Plant

Nativo Resources Plc (LON:NTVO), a gold-focused mining company with interests in Peru, is pleased to provide an update on pre-construction progress at La Patona Gold Ore Processing Plant ("GOPP"), located in Acarí, 45km from the Tesoro Gold Concession.

Nativo has completed the GOPP design and selected equipment suppliers for all material components of the plant. Suppliers have been selected and prices and delivery times agreed for the following works:

· Fabrication, transport and installation of new water borehole and pump

· Electrical works including a 1.8 km 500 kV cable to connect the plant to the power grid

· Ore crushing unit with a capacity of 350 tpd with two milling units

· 150 tpd flotation circuit (stage 1) plus centrifuges and agitators to accommodate lower third-party ore

· 70 tpd lixiviation circuit (stage 1) plus centrifuges and agitators, designed for processing higher grade ore

· Chemical and metallurgy laboratory to assay the ore, concentrates, and doré bars

· Smelting circuit with a daily output of 7-8 kg producing gold doré bars

In addition, the Company will imminently be awarding a contract for the following civil works which are due to commence in late November 2025:

· Groundworks

· Access and internal roads

· Geomembrane liner for the tailings facility

Nativo is preparing the submission of technical updates for its Environmental Management Instrument for Formalization permit (IGAFOM by its acronym in Spanish) required to operate the GOPP under the Registro Integral de Formalización Minera (REINFO) system.

Based on the current GOPP project schedule and scope of works, Nativo expects the GOPP to become operational and commence ore processing in Q2 2026.

Once the first phase is completed and the GOPP is operating at full capacity, it will be capable of outputting between 1.48 kg and 1.67 kg of gold in doré bars per day (subject to suitable supply of ore being maintained). Phase 2, which involves scaling up capacity by the third year, will increase production up to 3 kg per day.

Update re Santa Cruz Sur, Argentina

Considering Nativo's focus is now exclusively on advancing its precious metals opportunities in Peru, the Board has decided to exit the Company's remaining legacy oil and gas interest in Argentina. Accordingly, Nativo has transferred its 5% interest in the Santa Cruz Sur concessions to the operator, Interoil Exploration and Production ASA, for nil consideration. The assets have been loss-making since 2023 and Nativo's shareholding had been fully written down in the Company's 2023 Annual Report and Accounts.

Stephen Birrell, Chief Executive Office of Nativo, commented:

"We are pleased with the procurement progress being made at the plant. We have a clear objective to become an integrated regional gold producer, handling both Nativo's own and third-party material. We are developing the plant to be capable of processing both high and lower grade ores, providing a competitive advantage over other regional tolling plants which typically do not accommodate lower grade ores from the artisanal and small-scale miners. We look forward to commencing civil works on site and formalising the equipment orders in the coming weeks."
