Atico Intercepts Additional High Grade Zones Including 32.9g/t Au, 237g/t Ag, 16.25%

Cu, and 2.16% Zn Over 1.31 Meters at La Plata VMS Project, Ecuador

Vancouver, July 20, 2020 – Atico Mining Corporation (TSX.V: ATY | OTC: ATCMF) (“Atico” or the

“Company”) is pleased to announce three holes from its ongoing drill program at the La Plata precious

metals-rich volcanogenic massive sulphide (“VMS”) project in Ecuador. These three holes are designed

to target the South Block to test for possible continuity as well as mineralisation outside of the known

envelope.

Alain Bureau, President, commented: “Results are constantly showing the impressive high-grade nature

of the La Plata project as well as the thickness of the mineralization . We are also very pleased to see

positive results in our efforts to expand the mineralized footprint by reporting mineralization outside of

the existing envelope.”

True widths are dependent on uncertainties in the local strike and dip of the mineralization and are

estimated to be between 76% and 83% of the drill intercept.

Infill Drilling Program

• CMLP-20-104: was drilled outside of the known mineralized envelope and reports additional

mineralisation to the south of the La Plata. The intercept starts with 8 meters of massive and

semi massive sulfide composed of sphalerite and finishes in a mineralised stockwork zone.

• CMLP-20-105: was drilled to test the edge of the existing envelope at the bottom of the South

Block, reporting a massive sulfide with spectacular inte rcepts of zinc within sphalerite which

deeper transitioned to end in chalcopyrite.

• CMLP-20-106: is positioned within the south body for infill purposes. The intercept starts in 8

meters of massive sulfide mineralisation and continues in a stockwork zone. It cut mostly highly

mineralised chalcopyrite and finishes in sphalerite and pyrite.

The 2020 La Plata exploration program includes 11,000 meters of diamond drilling and is intended to

infill the south and north blocks of the La Mina area while upgrading the known mineralised resources

from the inferred category. This program is also designed to increase the known resources at the main

La Mina VMS lenses while providing the necessary samples to further metallurgical testing along with

geotechnical investigations. When completed, these new findings and results will then be included in the

upcoming feasibility study, planned for 2021.

Drill holes are planned to continue testing mineralization mainly at depth and along strike of the La Mina

area while also stepping out 275 meters north to further test the Guatuza target area. The previous

operator of the property reported high grade valu es from their earlier trenching program at the Guatuza

target. These results included a surface trench cutting 2.5m of 5.36 g/t Au, 71.18 g/t Ag, 2.14% Cu,

3.22% Pb & 10.86% Zn as reported in Toachi Mining Inc. press release dated January 16, 2019.

Infill Drill Program Assay Results:

*True widths are dependent on uncertainties in the local strike and dip of the mineralization and are

estimated to be between 76% and 83% of the drill intercept.

La Plata Project

Gold-bearing sulphide mineralization at La Plata occurs as compositional banding composed of

chalcopyrite, sphalerite and pyrite laminae with barite occurring as clasts and also as layers. The

mineralised lenses have also been dislocated by a few faults and dolerite dikes cutting the body.

The La Plata project is amongst the highest-grade gold-copper VMS deposits in which base and precious

metal mineralization is interpreted to have formed as part of multiple volcanic episodes that created a

stacked volcanic -exhalite hydrothermal sequence considered favorable for hosting additional VMS

lenses. The recent drilling results in the southern portion of the deposit have encountered deeper

mineralisation, and an extension of mineralisation to the nort h has been discovered by recent trenching

results.

The La Plata independent Preliminary Economic Assessment (“PEA”) dated March 30th 2019, was

prepared pursuant to National Instrument 43 -101 (“NI 43 -101”) and reports the La Plata inferred

resources at 1.9 million tons at an average grade of 4.1 g/t Au, 49.4g/t silver, 3.3% Cu, 4.5% Zn, 0.6%

Pb as available on SEDAR.

The La Plata project consists of two concessions covering a total area of 2,300 hectares along its 9-

kilometer length, which contains known mineralization in two VMS lenses and nine priority exploration

targets.

Quality Assurance & Quality Control

Before sampling, a centreline, representing bottom of hole (or a reference line when this is not known)

is marked on the drill core. The core is cut and sampled, always sampling the right-hand side of the drill

core. Samples are selected based on logged geological features, such as rock type, mineralization,

alteration, veining etc. Sample length does not exce ed 2.5 m nor is smaller than 20 cm. A total of 10%

of the samples submitted are certified blanks and standards and field duplicates with, as a minimum, one

blank submitted at the beginning of each sample batch. Certified standards are submitted at an avera ge

of 6% of the samples submitted. Field duplicates are taken at a rate of 1 in 20 of the samples taken. For

all drill holes, analysis was completed by ALS Chemex in North Vancouver with sample preparation

completed in Quito. The lab is accredited with Int ernational Standards ISO/IEC 17025:2005 and ISO

9001:2015.

All major ALS Geochemistry analytical laboratories are accredited to ISO/IEC 17025:2005 for specific

analytical procedures.
