ABOUT OROCO

The Company holds a net 85.5% interest in those central concessions that comprise 1,173 hectares

“the Core Concessions” of The Santo Tomas Pr oject, 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 Co re Concessions (for a total Proj ect area of 9,034 hectares, or

22,324 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 Project hosts

significant copper porphyry mine ralization initially defined by prior explorati on spanning the

period from 1968 to 1994. During that time, the 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 Augus t of 2024, which studies are available at the

Company’s website www.orocoresourcecorp.com and by reviewing the Company profile on

SEDAR+ at www.sedarplus.ca.

The Santo Tomás 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.
