VANCOUVER, British Columbia – (April 25, 2023) Oroco Resource Corp. (TSX-V: OCO, OTC:

ORRCF) (“Oroco” or “the Company”) announces a correction to the assay results from drill hole

N044 of its North Zone drilling program at its Santo Tomas property (the “ Property”) announced

on April 20, 2023. A data transfer error occurred in the transfer from one system to another in

the calculations conducted by a third-party consulting firm (see Table 1, below).

values are not used in the CuEq calculations.

Richard Lock, Oroco’s CEO, commented: “Drill hole N044 remains the best drill hole of the 2021-

2023 Santo Tomas drill program and is consistent with prior North Zone drill results. This data

correction in no way dampens our enthusiasm for the overall results we have received in our

recently completed drill program. We look forward to presenting those results in our upcoming

mineral resource estimate.”

This correction does not affect any other information in the April 20, 2023 news release or any

previous news release.

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, totalling 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 Company has completed its 2021-2023 drill program at Santo Tomas with a total of

48,481 meters drilled in 76 diamond drill holes to date.

The Santo Tomas Project is located within 160 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

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