Atico Reports Financial Results for Third Quarter of 2021 and Provides Corporate Update

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

Atico Mining Corporation (the "Company" or "Atico") (TSX.V: ATY | OTCQX: ATCMF) today announced its financial results for the three months ended September 30, 2021 ("Q3-2021"), posting income from mining operations of $13.8 million and a net income of $7.6 million.

Fernando E. Ganoza, CEO and Director, commented, "During this quarter the operation improved most of the production metrics relative to the first half of the year, however we saw a slight increase in cash cost during this period mainly driven by a lower copper head grade and metal output. The costs were mostly mitigated by higher realized metal prices leading to a cash margin of $2.86 per pound of payable copper as the Company broke records in most financial metrics for a single quarter. We closed this period showing a good cash position of $14.3 million along with $15.0 million in trade receivables which should be realized in the following weeks." Mr. Ganoza continued, "As we continue to take full advantage of the higher metal price environment, we are expecting to achieve record revenues and earnings for the year."

Third Quarter Financial Highlights

• Net income for the three months ended September 30, 2021 ("Q3-2021") amounted to $7.6 million, compared with $1.9 million for the comparative period ("Q3-2020"). The significant increase in net income was due to increase of concentrate shipped and invoiced and a higher realized copper price, as compared to Q3-2020.
  
  
• Sales for the period increased 126% to $31.8 million when compared with $14.1 million in Q3-2020. Copper ("Cu") and gold ("Au") accounted for 85% and 15% of the 16,184 (Q3-2020 - 9,291) dry metric tonnes ("DMT") shipped and invoiced during Q3-2021. The average realized price per metal on invoicing was $4.26 (Q3-2020 - $2.98) per pound ("lb") of copper and $1,782 (Q3-2020 - $1,991) per ounce ("oz") of gold.
  
  
• Working capital was $22.8 million (December 31, 2020 - $22.5 million), while the Company had $6.2 million (December 31, 2020 - $6.8 million) in long-term loans payable.
  
  
• Cash costs ^{( 1)} were $111.49 per tonne of processed ore and $1.40 per pound of payable copper produced ⁽²⁾ , which were a decrease of 2% and an increase of 24% over Q3-2020, respectively. The increase in the cash cost per pound of payable copper net of by products is mainly explained by a decrease in copper production due to a lower processed head-grade than in the same quarter of last year.
  

• Cash margin ^{( 1)(2)} was $2.86 (Q3-2020 - $1.85) per pound of payable copper produced, which was an increase of 54% over Q3-2020.
  
  
• All-in sustaining cash cost per payable pound of copper produced ^{( 1)(2)} was $2.19 (Q3-2020 - $1.54).

Corporate Update

The Company announced in its press release dated July 22, 2021, that it is currently in the process of renewing the title on its claims hosting the El Roble property, which under the current agreement are set to expire in January 2022. This process is still ongoing. The Company is working diligently with the authorities and believes it has followed and fulfilled all of the renewal requirements. However, at this time, the title has not been renewed and there is no assurance that it will be renewed. If the new title is not granted on or before January 23, 2022, the Company will be forced to halt mining operations. That outcome would be materially adverse for the Company since it will have no cash flow from operations and will be required to change its priorities. The Company will continue to firmly pursue the renewal of the title and will advise the market of any developments as they occur.

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 of two concessions covering a total area of 2,300 hectares along its 4-kilometer length, which contains known mineralization in two VMS lenses and nine priority exploration targets.
