ABOUT OROCO

The Company holds a net 85.5% interest in those ce ntral 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). 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 c opper porphyry mineralization initially defined by prior

exploration spanning the period from 1968 to 1994. During that time, the Project area was tested by over

100 diamond and reverse circulation drill holes, tota ling 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, wh ich 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 co rridors 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.
