- Tesoro Minerals Corp. Tesoro Minerals Corp. (TSX-V: TES; OTC: NNGVF) is a Canada-based junior mineral exploration company focused on the acquisition, exploration, and evaluation of resource properties primarily in Western South America, including Peru and historical interests in Colombia; the company targets epithermal gold-copper systems and operates through its wholly-owned Peruvian subsidiary Horizonte Agro Minero S.A.C. Founded in 1987 and headquartered in Vancouver, British Columbia, Tesoro Minerals maintains a portfolio of early-stage exploration assets in underexplored mining belts, with management leveraging extensive regional experience to advance projects from discovery through development. In July 2025, the company signed a definitive agreement with Globetrotters Resource Group Inc. to acquire a 100% interest in the Rumichaca and Cerro Macho epithermal gold-copper projects in south-central Peru, pivoting its focus toward high-impact discoveries in one of Peru's least explored districts while planning the divestiture of non-core concession applications in the Piura Region. Additionally, in June 2025, Tesoro completed a 1-for-4 share consolidation approved by shareholders to improve its capital structure, positioning it better for financings to support acquisitions and exploration at its key Peruvian assets.
