ATICO REPORTS CONSOLIDATED FINANCIAL RESULTS FOR 2023

Atico Mining Corp. has released its financial results for the year ended Dec. 31, 2023, posting income from mining operations of $7.4-million and a net loss of $5.8-million. Production for the year at Atico's El Roble mine totalled 13.2 million pounds ("lbs") of copper and 10,149 ounces ("oz") of gold in concentrate at a cash cost of $2.04 per payable pound of copper(2). (all amounts expressed in U.S. dollars, unless otherwise stated)

Fernando E. Ganoza, CEO and Director, commented, "we had a challenging year overall, with the first half of the year facing lower than expected head grades and lower throughput due to mechanical and operational issues, coupled with a significant appreciation in the Colombian Peso throughout the year which materially increased our costs. Despite these challenges the team did a great job getting El Roble mine back on track in the second half of the year to deliver just slightly below our annual guidance. This turnaround in operations and strong metal prices resulted in generation of good cash flows at the mine which were offset by a non-cash impairment charge recorded for the year." Mr. Ganoza continued, "In 2024, we will continue looking at opportunities to optimize operating costs while investing in expanding the resource and reserves estimate at El Roble and extending its mine life. In parallel, the La Plata project continues to advance with the permitting process and the Feasibility Study which is nearing completion."

2023 Consolidated Financial Highlights

• Net loss for 2023 amounted to $5.8 million, compared with $3.4 million for the comparative year. The loss was primarily due to an impairment charge to mineral properties, in respect to certain regional exploration targets in Colombia of the El Roble's exploration & evaluation segment, and lower income from mining operations because of lower sales and higher production costs.
• Sales for the year decreased 12 per cent to $57.5 million when compared with $65.2 million in 2022. Copper ("Cu") and gold ("Au") accounted for 83 per cent and 17 per cent of the 31,763 (2022 - 36,655) dry metric tonnes ("DMT") sold during 2023. Sales during the year were impacted by lower quantities sold compared to 2022.
• The average realized price per metal was $3.94 (2022 - $3.80) per pound of copper and $2,009 (2022 - $1,797) per ounce of gold.
• Working capital was negative $2.1 million (2022 - positive $18.2 million), while the company had $6.0 million (2022 - $15.6 million) in long-term loans payable. The decrease in working capital is largely due to the $10M loan payable to Trafigura PTE Ltd. becoming due within 12 months from December 31, 2023.
• Cash costs were $129.99 per tonne of processed ore and $2.04 per pound of payable copper produced, which were a decrease of 1 per cent and an increase of 39 per cent relative to 2022, respectively. Loss from operations was $4.4 million (2022 - income of $9.2 million) which included a $5.7 million impairment charge discussed above, while cash flows from operations, before changes in working capital, was $9.7 million (2022 - $15.8 million).
• Cash used by investing activities amounted to $15.9 million (2022 - $14.1 million) with expenditures for $5.5 million at El Roble and $5.5 million at La Plata. The company also paid $3.6 million to the National Mining Agency in Colombia (2022 - $3.4 million) and $1.0 million towards the deferred purchase price amount for the La Plata non-controlling interest acquisition completed in 2022. The final amount remaining of $1.0 million is due in August 2024.
• All-in sustaining cash cost per payable pound of copper produced was $2.87 (2022 - $2.43).

2023 Consolidated Operating Highlights and Review

• Ore processed increased 16 per cent year-on-year;
• Copper head-grade decreased 22 per cent year-on-year;
• Gold head-grade decreased 18 per cent year-on-year;
• Concentrate production decreased 8 per cent year-on-year;
• Copper metal production decreased 12 per cent year-on-year; and
• Gold metal production decreased 9 per cent year-on-year.

Operationally, the company had a challenging first half of the year resulting in low ore and concentrate production and low copper head grade. This was turned around in Q3-2023 with an improvement in these metrics to finish the year delivering just under the bottom end of our copper and gold production guidance ranges for 2023.

In 2023, the company produced 13.2 million lbs of copper, 10,149 oz of gold, and 36,949 oz of silver. The decrease in copper and gold production compared to the prior year is mainly explained by a decrease in head grade, which was partially offset by an increase in ore processed which met the guidance for the year.

During 2023, the mill operated for 339 days, an increase of 3 per cent compared to the target set for the year and an increase of 12 per cent compared to 302 days of operation in 2022. Average copper head-grade decreased by 22 per cent relative to 2022, meeting the bottom end of the 2023 guidance range, while average gold head-grade decreased by 18 per cent relative to 2022, slightly below the bottom end of the 2023 guidance range. Recoveries remained steady at 91.8 per cent (2022 - 91.4 per cent) for copper and 60.1 per cent (2022 - 60.6 per cent) for gold.

Cash costs were $129.99 per tonne of processed ore and $2.04 per pound of payable copper produced, which were a decrease of 1 per cent and an increase of 39 per cent relative to 2022, respectively. The increase in cash costs per pound of payable copper produced compared to 2022 is due to lower copper grade and lower gold (by-product) credits due to lower gold grade.

The financial statements and MD&A are available on SEDAR and have also been posted on the company's website at http://www.aticomining.com/s/FinancialStatements.asp

Fourth Quarter Financial Highlights

During the quarter, the company generated sales of $17.3 million, where copper accounted for 89 per cent and gold for 11 per cent. The average realized price per metal was $3.86 per pound of copper and $2,053 per ounce of gold, and included copper and gold price adjustments on shipments provisionally invoiced in prior quarters whose final settlement occurred during Q4-2023 as per their quotational periods. Income from mining operations for the quarter was $2.3 million and net cash provided by operating activities amounted to $3.5 million, which included operating cash inflows before changes in non-cash operating working capital items of $2.0 million and cash inflows from changes in non-cash working capital items of $1.5 million. Cash costs for the quarter were $135.00 per tonne of processed ore and $1.91 per pound of payable copper produced(2) (4), increases of 7 per cent and 1 per cent over Q4-2022, respectively.

Annual General Meeting

Atico Mining cordially invites all shareholders to its Annual General Meeting of Shareholders, at 10:00 am, Tuesday, June 18, 2024, at Suite 501 - 543 Granville Street, Vancouver, British Columbia.

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's reserves estimate, with an effective date of September 30, 2020, included in the NI 43-101 Technical Report dated February 18, 2021, and filed on SEDAR on the same date, includes Proven and Probable reserves of 1.00 million tonnes grading 3.02 per cent copper and 1.76 g/t gold, at a cut-off grade of 1.3 per cent copper equivalent. 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. A focus in 2023 will be on increasing the resource and reserves estimate and extending the El Roble's life of mine.

La Plata Overview

The 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. In total, there is drill core and logs from more than 28,300 metres of drilling.

Historic resources based on drilling by Cambior and Cornerstone were estimated at 913,977 tonnes grading 8.01 grams gold per tonne, 88.3 grams silver per tonne, 5.01 per cent copper, 6.71 per cent zinc and 0.78 per cent lead per tonne in the inferred category. More recently, 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 per cent copper, 4.60 per cent zinc and 0.60 per cent lead per tonne.

The La Plata project consists of two concessions covering a total area of 2,235 hectares along its 9-kilometer length, which contains known mineralization in two VMS lenses and nine priority exploration targets.

The company is currently working on completing a Feasibility Study and obtaining the necessary permits and the environmental license to begin construction of the La Plata project.

In May 2022 the company received the technical approval of its Environmental and Social Impact Assessment ("ESIA") study for the project and the Ministry of Environment, Waters and Ecological Transition (MAATE) initiated the socialization of the ESIA, through an environmental public consultation process, as an important step for the issuance of the environmental license for the La Plata project. However, on July 31, 2023, the Constitutional Court in Ecuador, admitted for processing a claim of the Confederation of Indigenous Nationalities of Ecuador (CONAIE) and other complainants, provisionally suspending Executive Decree No 754 signed on May 31, 2023, that regulates environmental consultations for all public and private industries and sectors in Ecuador - not limited to extractive industries. The La Plata environmental consultation process was as result put on pause until a ruling was made from the Constitutional Court in Ecuador. On November 17, 2023, the Ecuadorian Constitutional Court ruled the Executive Decree 754 was unconstitutional, but decided to maintain the decree in force until the Ecuadorian National Assembly enacts this procedure into Organic Law. Until the Assembly passes the necessary organic law, the temporary suspension of the Decree was revoked by the Constitutional Court and the Decree remains in effect. This allows many projects across all industries and sectors, including La Plata, to resume their respective consultation process, which MAATE reinitiated for La Plata during Q1-2024.

In January 2024, the company announced that the Government of Ecuador authorized the extension period for the La Plata mining concession until 2049.
