Atico Continues to Intercept Bonanza Grades Including 6.8 Meters of 19.5g/t Au, 224g/t

Ag, 12.2% Cu, and 3.7% Zn at La Plata VMS Project, Ecuador

Vancouver, August 05, 2020 -- Atico Mining Corporation (the “Company” or “Atico”) (TSX.V: ATY |

OTC: ATCMF) is pleased to report additional high grade drill results from its 10,000 m eter drilling

program on the La Plata property in Ecuador. Today's results are from 3 holes completed in the South

Block as the drill program continues to c onfirm and expand the La Plata mineralized footprint with

bonanza grades gold & copper intercepts encountered within larger massive sulfides lenses.

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

The i nfill and step-out drilling program has been implement ed to upgrade and potentially expand

resources of the La Plata project. Two drill rigs are currently active on the project with one rig currently

starting to drill on the North Block in order to in-fill and potentially grow the La Plata resource.

The three diamond drill holes reported today successfully demonstrated the thickness and continuity of

the La Plata VMS lenses, as well as potential expansion of the mineralized envelope of the South Block.

• Hole CMLP-20-107 was collared above the known VMS envelope and reported good values of

precious and base metal grades within massive to semi -massive sulfides over a 5.66 meter

intercept mineralised mostly by sphalerite.

• Hole CMLP-20-108, drilled for infill purposes in the South Block, demonstrated continuity of

the mineralization with an intercept of 5.22 meters composed of both VMS and stockwork also

dominated by sphalerite.

• Hole CMLP-20-110, in addition to intercepting a high-grade VMS zone within the South

Body, cut a second intercept 10 meters below the main zone with 5.48 meters of mineralized

stockwork.

The Company also reports that it continues to intercept visible massive and semi-massive sulfide

mineralization as the ongoing drilling program continues, the core is currently being sent to the

lab for analysis and will be released in due course . This current step-out drilling is targeting

potential new zones that may lead to further extensio ns of the South Block mineralized

envelope. Additional drill holes are planned to continue testing VMS mineralization outside of

Page 2 of 4

the known envelope and along strike of the La Mina area . This includes stepping out towards

the north to further test the Guatuza target area which reported high grade values from the earlier

trenching program. The 2020 exploration program on the La Plata property, as well as the El

Roble drilling program are both fully fund ed from the highly profitable El Roble mining

operation in Colombia.

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 north 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.

The Company has a binding option agreement with a private Ecuadorean company to earn up

to 75% in the La Plata project, of which the first option to acquire the initial 60% ownership has

been exercised. Please refer to the Company’s MD&A for t he year ended December 31, 2019

for further details.

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 exceed 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 average 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 International 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.
