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, British Columbia, July 20, 2020 (GLOBE NEWSWIRE) -- 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.”

La Plata Drilling Highlights Include:

Hole	From (m)	To (m)	Interval (m)	Au (g/t)	Ag (g/t)	Cu (%)	Zn (%)
CMLP-20-104	415.75	424.00	8.25	14.60	303.37	0.34	2.10
Including	418.70	421.50	2.80	21.40	421.88	0.36	0.70
CMLP-20-106	387.59	390.70	3.11	16.55	156.95	10.67	7.64
Including	387.59	388.90	1.31	32.90	237.00	16.25	2.16

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 intercepts 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 values 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.

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 the 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.
