VANCOUVER, British Columbia, July 8, 2025 (TSX-V: TES) – Tesoro Minerals Corp., (“Tesoro” or the “Company”) is pleased to announce it has signed a definitive agreement with Globetrotters Resource Group Inc. (“Globetrotters”) to acquire a 100 % interest in the Rumichaca and Cerro Macho epithermal gold-copper projects in south-central Peru.
“These acquisitions pivot Tesoro toward high-impact gold–copper discovery in one of Peru’s least explored belts,” said Scott McLean, CEO. “We will focus our exploration budget on Rumichaca and Cerro Macho while advancing the planned divestiture of our non-core concession applications in the Piura Region.”
Highlights
- Two new high-sulphidation epithermal prospects secured – the Rumichaca (900 ha) and Cerro Macho (2,500 ha) Au-Cu projects.
- Strategic location: 3,400 ha in total within Peru’s Miocene Porphyry–Epithermal Belt, an emerging district in south-central Peru.
- Compelling geology: Advanced-argillic alteration, anomalous Au-Cu-Mo values and pathfinder elements point to large, fertile mineralizing systems.

Geological Setting |
High-sulphidation lithocap with pervasive advanced-argillic alteration. |
Extensive lithocap with silica-alunite alteration and local vuggy silica. |
|
Key Results |
Rock sampling: up to 0.39 g/t Au with anomalous Cu-Mo. |
Rock sampling: up to 0.42 g/t Au plus elevated As and Ba. |

Exploration Plan |
– 10 line-km Induced Polarization (IP) survey – Detailed mapping & rock/soil geochemistry |
– 10 line-km IP survey – Detailed mapping & rock/soil geochemistry |
Both properties show alteration and geochemical signatures typical of the upper levels of large, high-sulphidation epithermal and porphyry systems. Tesoro’s initial goal is to define chargeability/resistivity anomalies and drill targets beneath shallow cover.
Piura Concession Applications
Tesoro holds 21 concession applications (≈ 18,700 ha) in the Las Lomas and Tambogrande districts, Piura Region. Consistent with its sharpened focus on the Miocene belt, Tesoro intends to divest these non-core applications in the coming weeks and will update the market as developments occur.
