Vancouver, British Columbia – (July 17th, 2025) – Sendero Resources Corp. (TSXV: SEND) (the “Company” or “Sendero”) is delighted to announce that it has executed a definitive option agreement with Energía y Minerales Sociedad del Estado (“EMSE”), the Energy and Minerals State Society of La Rioja, Argentina, which replaces the original option agreement dated March 4th, 2024 (see the Company’s news release of March 5th, 2024).

The Company is pleased to formalize its rights to these exploration claims, which together with the already owned adjacent Peñas Negras project, makes this one of the largest contiguous land positions in the Vicuña district, a district that is highly prospective for copper and gold projects and mines, and where there is already mineralization based on historical drilling.  The new option agreement continues to apply to EMSE’s claims consisting of eight exploration claims, covering a total area of 9,177 hectares (91.7 km²), which are contiguous with and east of the Company’s 100% owned Peñas Negras Project, a copper-gold exploration project spanning 12,000 hectares (120 km²). The total project area comprises 21,177 hectares (211.77 km2)(see Figure 1).

“We are pleased to continue to work with EMSE and the Province of La Rioja to unlock the potential of our district-scale land package.  We are steadfast in our mandate to move exploration forward, ensuring that the benefits of development are shared equitably with the people of La Rioja.  We are working on delivering our initial exploration program so that we are ready for the next field season”, said Alex Gostevskikh, Chief Executive Officer of Sendero.
