About Nativo Resources plc (formerly Echo Energy plc)

Following the partial divestment of its assets in Argentina, Nativo entered into a 50:50 joint venture in Peru in July 2024 with an experienced local partner for precious metals (gold/silver) mining and the cleaning of known tailings deposits containing Measured and Indicated resources of gold and silver. Through the JV, known as Boku Resources, Nativo has secured an opportunity to scale operations in Peru producing gold and silver through primary mining and tailings cleaning, owning 50% of the production and resources. Initially, Boku intends to establish formalised artisanal and small mining operations on its 100% held Tesoro Gold concession, southern Peru, targeting early cash flow generation by Q4 2024.
