ABOUT OROCO

The Company holds a net 87.0% interest in those central concessions that comprise 1,173 hectares "the Core Concessions" of the Santo Tomas Project, located in northwestern Mexico. The Company also holds an 80% interest in an additional 7,861 hectares of mineral concessions surrounding and adjacent to the Core Concessions (for a total Project area of 9,034 hectares, or 22,324 acres). Following an assessment of one of the non-Core Concessions, the Company filed an application to reduce the area of that concession, with the result that the additional concessions will total 4,948.24 hectares, for a total Project area of 6,121.11 hectares or 15,124.47 acres. The Project is situated within the Santo Tomas District, which extends up to the Jinchuan Group's Bahuerachi Project, approximately 14 km to the northeast. The Santo Tomas Project hosts significant copper porphyry mineralization initially defined by prior exploration spanning the period from 1968 to 1994. During that time, the Santo Tomas Project area was tested by over 100 diamond and reverse circulation drill holes, totaling approximately 30,000 meters. Commencing in 2021, Oroco conducted a drill program (Phase 1) at Santo Tomas, with a resulting total of 48,481 meters drilled in 76 diamond drill holes.

The drilling and subsequent resource estimates and engineering studies led to a revised MRE and an updated PEA being published and filed in August of 2024, which studies are available at the Company's website and by reviewing the Company profile on SEDAR+ at .

The Santo Tomas Project is located within 170 km of the Pacific deep-water port at Topolobampo and is serviced via highway and proximal rail (and parallel corridors of trunk grid power lines and natural gas) through the city of Los Mochis to the northern city of Choix. The property is reached, in part, by a 32 km access road originally built to service Goldcorp's El Sauzal Mine in Chihuahua State.
