Sendero Resources Expands Footprint in Argentina's Vicuña District with Option Agreement

Vancouver, British Columbia — July 17, 2025 — NewsWall — Sendero Resources Corp. (TSXV: SEND) has finalized an option agreement with Energía y Minerales Sociedad del Estado (EMSE) for exploration claims in La Rioja, Argentina, superseding the original agreement from March 4th, 2024.

The agreement secures Sendero's rights to claims adjacent to its Peñas Negras project, creating a significant land position in the copper and gold-rich Vicuña district. The new agreement covers 9,177 hectares contiguous to Sendero's 100% owned 12,000-hectare Peñas Negras Project, resulting in a total project area of 21,177 hectares.

According to CEO Alex Gostevskikh, Sendero aims to advance exploration while ensuring equitable benefits for the people of La Rioja. The company is preparing its initial exploration program for the upcoming field season.

Under the agreement, Sendero can acquire 100% interest in the EMSE claims by incurring US$5,000,000 in exploration expenses over five years, paying US$65,000 over five years, and granting a 1.0% NSR royalty over all the EMSE and Peñas Negras claims (which will become a 0.5% NSR royalty on the Peñas Negras claims if the option on the EMSE claims is not exercised).

Sendero Resources Corp. focuses on copper-gold exploration at its Peñas Negras Project in Argentina's Vicuña Belt, an area with geological similarities to other deposits. Multiple porphyry and high-sulfidation epithermal targets have been identified. The project is located near the Caserones mine, NGEx Minerals’ Lunahuasi project, and BHP-Lundin Mining’s Filo del Sol project.
