FOR IMMEDIATE RELEASE:

OROCO COMPLETES AIRBORNE MANETICS SURVEY AND UPDATES 3D IP

SURVEY PROGRESS AT SANTO TOMAS

VANCOUVER, British Columbia – (March 3, 2021) Oroco Resource Corp. ( TSX-V: OCO )

(“Oroco” or “ the Company ”) is pleased to announce the successful completion of the airborne

component of a helicopter magnetics survey over the Santo Tomas Project ( “the Project”), and to

provide an update on the 3D induced polarization survey in progress on the Project.

Magnetics Survey. The Company has completed a helicopter magnetics survey performed by

Terraquest Ltd. (“ TQ”) using a high sensitivity cesium vapour magnetometer, a gamma ray

spectrometer and TQ’s proprietary Matrix very low frequency electromagnetic (“ VLFEM”)

system. The survey was completed with the collection of 2,231 line kilometers of data with an east-

west tie-line separation of 50 metres and a north-south tie-line separation of 500 metres.

Independent quality monitoring of the survey is being provided by Condor Consulting, Inc. of

Lakewood, CO. The Company expects to receive the processed magnetics, VLFEM and

radiometric data from TQ within the next two months. The Company will then analyze the data to

assist in the mapping of the sub-surface geology of the Project.

3D IP Survey. Further to its news release of January 27, 2021, the Company has completed the

deep, three-dimensional Induced Polarization geophysical survey (“ 3D IP”) over the south eastern

extension to the project survey grid on the South Zone of the Project, closing off the eastern

extension of the South Zone chargeability feature.

The Company has now relocated the survey team to the Brasiles Zone in the northern part of the

grid and commenced the survey of the continuation of NNE striking, west-dipping, chargeability-

high response which the 3D IP survey has already demonstrated extends from the North Zone to the

prominent gossan of the Brasiles Zone. The Company is taking advantage of the current low water

levels in the Huites Reservoir to collect data from previously inaccessible areas, and will continue

the 3d IP survey for another 800 metres to the north. The Company may extend the survey further

in the event that the Brasiles chargeability feature has not been closed off. Subject to such

extensions, the DCIP survey is approximately 80% complete.

The relative outlines of the airborne magnetics and field-based DCIP geophysical surveys are

shown in the map in Figure 1.

ABOUT OROCO:

The Company holds a net 61.4% interest in the collective 1,172.9 ha core concessions of the Santo

Tomas Project in NW Mexico and may increase that majority interest up to an 81.0% interest with a

project investment of up to CAD$30 million. The Company also holds a 77.5% interest 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 Santo Tomas District, which extends from

Santo Tomas up to the Jinchuan Group’s Bahuerachi project, approximately 14 km to the 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 property 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.

The Santo Tomas Project is located within 160km 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

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