Oroco Announces the Start of Drilling at Santo Tomas

Exploration Programs

July 29, 2021 NEWS RELEASE

OROCO ANNOUNCES THE START OF DRILLING AT SANTO TOMAS

VANCOUVER, British Columbia – (July 29, 2021) Oroco Resource Corp. ( TSX-V: OCO;

OTCQB: ORRCF) (“Oroco” or “the Company”) is pleased to announce that it has commenced

diamond core drilling at its Santo Tomas copper project, with the first drill hole collared and in

progress. A second drill rig is scheduled to begin operating next week, and a third rig, constructed

for the Company by Hydracore Drills Ltd. of Canada, is in transit to the project. The drill hole

currently in progress is located in the North Z one and represents the first drill hole collared

anywhere on the property since 1993. The initial drilling is intended to c onfirm the presence of

historically defined pol ymetallic copper mineralization and to begin the development of new

mineral resource models at Santo Tomas.

Commenting on the start of drilling, Oroco’s CEO, Craig Dalziel, stated "We are extremely pleased

to be able to initiate a new generation of drilling at Santo Tomas at a time when the acceleration of

large copper projects is essential for global ec onomic growth and stability . We are anxious to

confirm and extend the historical resources at the North and South Zones, and to commence

exploration at the Brasiles Zone, where our 3D DCIP program indicated extensive and compelling

chargeability features.”

The initial holes in the drill program will be collare d in the North Zone and will be drilled at steep

angles to the East-Southeast. While heavy rains have impacted roads and mobilization, causing the

initial drill setups to be supporte d by helicopter, the rapidly rising reservoir has enabled the project

team to revert to waterborne support of the drilli ng program from the Co mpany’s existing Buena

Vista base camp. The light and highly (man-) portable drills being deployed by the Company allow

for drilling at favourable locations with no environm ental impact. Targeti ng for drilling is being

informed by the recently completed 3D DCIP surv ey which has defined significant chargeability

features that correlate well with mineralisation known from historical drill ing and which features

continue beyond the mineralization defined by that drilling.

ABOUT OROCO:

The Company holds a net 73.2% interest in the collective 1,172.9 ha Core Concessions of the Santo

Tomas Project in NW Mexico. The Company also holds a 77.5% in terest in 7,807.9 ha of mineral

concessions surrounding and adjacent to the Core Concessions (for a total project area of 22,192

acres). The Project is situated within the Sa nto Tomas District, which extends from Santo Tomas

up to the Jinchuan Group’s Bahuerachi project, a pproximately 14 km to th e north-east. Santo

Tomas hosts a significant copper porphyry deposit defined by prior exploration spanning the period

from 1968 to 1994. During that time, the propert y was tested by over 100 diamond and reverse

circulation drill holes, totaling approximately 30,000 meters. Based on data generated by these drill

programs, a historical Prefeasibility Study was completed by Bateman Engineering Inc. in 1994.

and is serviced via highway and proximal rail (and parallel corrido rs of trunk grid power lines and

natural gas) through the city of Los Mochis to th e northern city of Choix. The property is reached

by a 32 km access road originally built to service Goldcorp’s El Sauzal Mine in Chihuahua State.
