TESORO MINERALS CLOSES AGREEMENT WITH GLOBETROTTERS TO ACQUIRE RUMICHACA AND CERRO MACHO IN PERU

Tesoro Minerals Corp. has completed the acquisition of the Rumichaca and Cerro Macho properties from Globetrotters Resource Group Inc., which was previously announced on July 8, 2025.

The transaction was completed pursuant to the terms of an agreement dated July 7, 2025, under which the company acquired a 100-per-cent interest in two prospective epithermal gold exploration projects in Peru. The consideration provided by the company to Globetrotters includes the issuance of 1,425,000 common shares of Tesoro at a deemed price of eight cents per common share for an aggregate value of $114,000 and a 2-per-cent net smelter return royalty to Globetrotters. Tesoro may repurchase 1 per cent of the NSR for $1-million at any time prior to the completion of a feasibility study.

Both properties show alteration and geochemical signatures typical of the upper levels of large, high-sulphidation epithermal and porphyry systems. The company's initial goal is to define chargeability/resistivity anomalies and drill targets beneath shallow cover.

Initial exploration plan

The company plans to continue detailed lithological and alteration mapping, followed by geophysical surveys across both properties. The geophysical program will consist of approximately 60 line kilometres of induced polarization and magnetic surveys. The total cost of the program is estimated at approximately $300,000, inclusive of required community engagement and social initiatives in the project areas. The company believes it is adequately financed to complete this initial exploration program following its recently completed private placement (see news release dated Feb. 4, 2026).

TSX Venture Exchange approval

The company has received conditional approval of the TSX Venture Exchange for the transaction.

Qualified person

The technical elements of this news release have been approved by Scott McLean, PGeo (PGO), chief executive officer and director of Tesoro, a qualified person under National Instrument 43-101.
