Atacama Copper Provides Trenching Program

Update at the El Cofre Copper-Gold Project

Vancouver, British Columbia--(Newsfile Corp. - May 24, 2022) -

Atacama Copper Corporation (TSXV:

ACOP

) ("

Atacama Copper

" or the "

Company

") provides an update on its trenching program at its

100% owned El Cofre Copper-Gold Project.

Highlights:

40% of 3,000m trenching program completed

Multiple zones of copper oxide mineralization identified

Over 156 samples collected and analyzed by XRF to date

Copper-gold mineralization identified across 1 to 5 meter wide mineralized veins over a strike

length of 600m, with 800m remaining to be tested

Laboratory results expected in early June 2022

Gino Zandonai, CEO of Atacama Copper, said,

"

We are pleased to announce we are progressing on

schedule with the trenching program on the El Cofre copper project, and we have confirmed the

presence of copper mineralization along 600 meters strike into a 1.4km length of copper oxides

occurrences corridor. This program is the first phase of a more extensive work program on the project.

It is designed to gather additional targeting information and increase the knowledge of the type and

geometry of the mineralization, which allows for identifying a number of high-priority target zones

across the property."

Trenching program is currently 40% completed, including trenching, sampling, and mapping focused on

the Viñita area. The overall trenching program is planned to excavate around 3,000 meters over 18

designed trenches and channel sampling lines focused on the northern section of the project area, the

Viñita and Gloria areas.

The program is targeting existing mapped mineralized structures and

geochemical/geophysical anomalies. The completion of 18 trenches is subject to environmental

evaluation and clearance, of which 70% of the planned trenches have already been approved for

excavation.

The trench program to date has identified a fault-vein mineralized structure at Viñita, dipping 70° to the

west and shows pockets of high-grade mineralization.

In the Viñita South area the mineralised structure

has been mapped along a strike length of at least 600 m in length.

This sequence is part of a longer

1.4km long structural corridor of discontinuous mineralisation.

The mapped mineralized fault-vein's vary

between 1 to 5 meters in width with local combined structures up to 15 meters in width.

The mapped

veins are observed between 365 and 212 meters of elevation, which infers at least 150 meters of

vertical continuity to the mineralization.

The geological mapping has been supported by XRF measurement. Channel and rock chip sampling

are taken at one-meter intervals along the open trench. To date, referential XRF measurement (Olympus

Delta) has been taken systematically over 156 samples in the company warehouse and by a certified

operator to confirm and support the mineralization mapping of black oxides, copper-rich limonite, and

copper oxides in general. The results from certified laboratory analysis of the samples are expected in

early June 2022.

looking statements.

In this news release, forward-looking statements relate to, among other things, statements relating to

expectations regarding the exploration and development of the El Cofre and Placeton projects,

including planned exploration and drilling activities, and other statements that are not historical facts.
