Oroco Receives Positive Resolution from Mexico’s Environment Ministry
Vancouver, CANADA – August 13, 2025 – Oroco Resource Corp. (TSX-V: OCO; OTC: ORRCF)
(“Oroco” or the “Company”) is pleased to announce that it has received a positive resolution from
the Mexican Federal Secretaría del Medio Ambiente y Recursos Naturales (“SEMARNAT”) to its
“informe preventivo” notice of exploration activities on the Santo Tomas Project. As a result of the
positive resolution, the Company’s planned drilling and exploration activities “… do not require
obtaining the authorization in matters of Environmental Impact granted by t his Secretariat and
therefore can be carried out in accordance with the characteristics indicated in the IP presented for
the project.” Consequently, the Company may proceed with the scope of drilling and exploration
on the Santo Tomas Project set out in the notice without an Environmental Impact Authorization
from SEMARNAT.
“This positive response from SEMARNET is truly noteworthy,” stated Oroco’s Chairman, Craig
Dalziel. “It further increases our confidence in the overall cooperation and support of the Mexican
government and SEMARNAT regarding the Santo Tomas Project and provides an early example of
the positive effect of the project’s inclusion in Plan Sinaloa, the recently announced regional
development initiative.”
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 Project, located in northwestern Mexico. The
Company also holds an 80% interest in an additional 4,948 hectares of mineral concessions
surrounding and adjacent to the Core Concessions (for a total Project area of 6,121 hectares, or
15,125 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 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, 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.
Subsequent to the drilling at Santo Tomas, the 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 online at the Company’s website at 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.
