Atico Mining Corporation (TSX.V: ATY | OTCQX: ATCMF) ("Atico" or the "Company") is pleased to announce additional positive results for the exploration program being carried out in an area of historical mining to expand tonnage at the El Roble mine. In addition, the Company reports the results for seven diamond drill core holes (see Table 1 below), which included 12.0m of 8.50% Cu, 7.23gt Au and 7.80m of 4.71% Cu and 7.24gt Au.
"We are pleased to report that our mine vicinity drill campaign continues to intercept mineralization and extends the main historic massive sulphide body at the El Roble deposit. This area was mined by operators previous to Atico obtaining control of the mine on November 22, 2013," said Fernando E. Ganoza, CEO. "These results continue to increase confidence in our view that additional high-grade copper and gold mineralization remains both within the historically defined bodies and beyond the previously outlined mineralized shell. These strong assay results are open at depth and along strike and we will continue the drill program in this vicinity and into the second half of the year at which time the Company plans to update the resource estimate."
Exploration Drilling Results Include:

True widths are dependent on uncertainties in the local strike and dip of the mineralization and are estimated to be between 90% and 95% of the drill intercept.

Exploration Drilling Program
The goal of the current surface and underground drilling program at the El Roble mine is to define zones of mineralization within the extent of main historic massive sulphide body that were not exploited by previous operators and also to expand the historically identified resource. During the first quarter of 2023, the Company began a drill program to test the main mineralized body and the immediately adjacent area. A total of 3,765 meters of drilling are planned for 2023, of which final results for ten drill holes that have a mineralized intercept have been received.
Revision to Previously Reported Results

Anomaly 8
Anomaly 8 has been drill tested with 7 DDH completed to date for a total of 3,792 meters. The target was selected based on a strategic review of historical and recent exploration programs and lies within the favorable stratigraphy that hosts the currently producing high grade Cu/Au VMS El Roble mine. Anomaly 8 is defined by values from surface outcrop of up to 11% Cu within a hydrothermal breccia coincident with a 900m by 300m area of soil and rock copper anomalies, electromagnetic and magnetic geophysical anomalies. Strong alteration with massive sulfide fragments and stringers were intersected in drill holes cutting the target horizon at vertical depths of more than 300 meters below the mineralization that occurs at surface. Elevated copper, zinc, and silver values were returned from core samples as follows (see also the Image 2. below):
ATDHAN8-007: 25 m. @ 0.4% Cu Inc 7.3 m. @ 0.64 % Cu
ATDHAN8-004: 20 m. 856 ppm Zn, 5 ppm Ag

El Roble Mine
The El Roble mine is a high grade, underground copper and gold mine with nominal processing plant capacity of 1,000 tonnes per day, located in the Department of Choco in Colombia. Its commercial product is a copper-gold concentrate.
Since obtaining control of the mine on November 22, 2013, Atico has upgraded the operation from a historical nominal capacity of 400 tonnes per day.
El Roble has Proven and Probable reserves of 1.00 million tonnes grading 3.02% copper and 1.76 g/t gold, at a cut-off grade of 1.3% copper equivalent with an effective date of September 30, 2020. Mineralization is open at depth and along strike, and the Company plans to further test the limits of the deposit.
On the larger land package, the Company has identified a prospective stratigraphic contact between volcanic rocks and black and grey pelagic sediments and cherts that has been traced by Atico geologists for ten kilometers. This contact has been determined to be an important control on VMS mineralization on which Atico has identified numerous target areas prospective for VMS type mineralization occurrence, which is the focus of the current surface drill program at El Roble.
