(All amounts expressed in US dollars, unless otherwise stated)

Atico Mining Corporation (the "Company" or "Atico") (TSX.V: ATY | OTC: ATCMF) today announced its financial results for the three months ended March 31, 2022, posting income from mining operations of $9.1 million and a net income of $3.9 million. Production for the period at Atico's El Roble mine totaled 4.7 million pounds ("lbs") of copper and 2,636 ounces ("oz") of gold in concentrate at a cash cost (1) of $1.29 per payable pound of copper (2) .

Fernando E. Ganoza, CEO and Director, commented, "We are pleased to report strong financial results despite selling only one concentrate shipment in the period. These results were underpinned by operations exceeding our copper and gold production targets while coming under budgeted cash costs for the quarter." Mr. Ganoza continued, "As we continue to benefit from strong financial results, our ability to carry out the planned growth programs at both El Roble and La Plata will be enhanced. At La Plata, the focus continues to be on the feasibility study and advancing the permitting process. At El Roble we will be putting an emphasis on mine vicinity drilling, looking for extensions of mineralization at depth and along strike."

First Quarter Financial Highlights

• Net income for the quarter amounted to $3.9 million, compared with $1.2 million for the same period last year. The increase in net income was primary due to higher income from operations in Q1-2022 and a $2.3M fair-value loss for metal hedging recorded in Q1-2021.
  
  
• Sales for the quarter increased 7% to $20.6 million when compared with $19.3 million in Q1-2021. Copper ("Cu") and gold ("Au") accounted for 89% and 11% of the 9,568 dry metric tonnes ("DMT") sold during Q1-2022.
  
  
• Working capital was $30.0 million, while the Company had $15.5 million in long-term loans payable.
  
  
• The Company entered into a secured definitive credit agreement with Trafigura PTE Ltd. for a facility with a term of 30 months. The total principal of $10 million withdrawn will bear interest at a rate of LIBOR plus 5% for the first 24 months and then at a rate of LIBOR plus 7.5% thereafter.
  
  
• The average realized price per metal on provisional invoicing was $4.65 per pound of copper and $1,978 per ounce of gold.
  
  
• Cash costs ^{( 1)} were $125.21 per tonne of processed ore and $1.29 per pound of payable copper produced ⁽²⁾ , which were decreases of Nil% and 25% over Q1-2021, respectively.
  
  
• Cash margin ^{( 1)(2)} was $3.36 per pound of payable copper produced, which was an increase of 44% over Q1-2021.
  
  
• All-in sustaining cash cost per payable pound of copper produced ^{( 1)(2)} was $2.04.
  

First Quarter Summary of Financial Results

First Quarter Operational Review

In Q1-2022, the Company produced 4.7 million lbs of copper, 2,636 oz of gold, and 8,779 oz of silver. When compared to the same period in 2021, production increased by 7% for copper and 24% for gold. The increases for both copper and gold are mostly explained by the increase in head-grades for the period. Copper recoveries slightly decreased when compared to the same period last year, while gold recoveries during the quarter improved over Company's projections.

Cash costs ⁽¹⁾ were $125.21 per tonne of processed ore and $1.29 per pound of payable copper produced ^{( 2 )} , which were decreases of Nil% and 25% over Q1-2021, respectively (refer to non-GAAP Financial Measures). The decrease in cash cost per pound of payable copper produced is due to an increase in gold by-product credits and in copper head-grade than in prior year, resulting in a higher payable copper production.

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.

La Plata Overview

Atico's wholly-owned La Plata project is a gold rich volcanogenic massive sulphide deposit that was the subject of small-scale mining from 1975-1981 by Outokumpu Finland. The project benefits from a modern drill and exploration database which was completed by Cambior Inc. from 1996-1999, Cornerstone Capital from 2006-2009 and Toachi from 2016-2019.

Toachi Mining completed a PEA estimating an inferred resource of 1.85 million tonnes grading 4.10 grams gold per tonne, 50.0 grams silver per tonne, 3.30% copper, 4.60% zinc and 0.60% lead per tonne.

The La Plata project consists two concessions covering a total area of 2,235 hectares along its 4-kilometer length, which contains known mineralization in two VMS lenses and nine priority exploration targets.
