Atico Produces 2.24 Million Pounds of Cu and 1,906 Ounces of Au in Third Quarter 2025
Atico Produces 2.24 Million Pounds of Cu and 1,906 Ounces of Au in Third
Quarter 2025
VANCOUVER, British Columbia, Oct. 21, 2025 -- Atico Mining Corporation (the “Company” or “Atico”) (TSX.V: ATY | OTCQX:
ATCMF) announces its operating results for the three months ended September 30, 2025 from its El Roble mine. Production
for the quarter totaled 2.24 million pounds of copper and 1,906 ounces of gold in concentrates, a decrease of 23% for copper
and 8% for gold, respectively, over the same period in 2024.
“During the period, higher metal prices enabled profitable mining of ore from lower mine zones previously excluded from
reserves, leading to a quarterly revision of the mine plan to incorporate this out-of-reserve material. These areas of the deposit
are in the final months and are being prioritized to maximize overall ore recovery. The lower grade, newly converted reserves,
offset the contribution from the higher-grade upper zones, which percentage of feed to the mill has been consistently
increasing as development continues and more stopes enter production. Given the change in the mine plan, results for the
quarter were below budget, in particular for the copper head grade, which increased from the previous quarter but not as much
as initially forecasted,” stated Fernando E. Ganoza, CEO. “We anticipate production for the following quarter will improve
driven by higher copper head grade, even though we will continue to maximize ore recovery in the lower zones, as this
strategy, coupled with the current drill program, should help us increase the reserves and the life of mine.”
Third Quarter Operational Highlights
• Production of 2.24 million pounds of copper contained in concentrates; a decrease of 23% over Q3 2024.
• Production of 1,906 ounces of gold contained in concentrates; a decrease of 8% over Q3 2024.
• Average processed tonnes per day of 741, a decrease of 3% over Q3 2024.
• Copper head grade of 1.82%, a decrease of 14% over Q3 2024.
• Gold head grade of 1.53 grams per tonne; no significant change over Q3 2024.
• Copper and gold recovery of 91% and 63%; no significant change for copper and gold, respectively, over Q3 2024.
Third Quarter Operational Review
The El Roble mine has been undergoing a transition from the lower areas of the mine towards the new higher-grade reserves in
upper areas. This planned transition schedule has been changed to take advantage of higher metal prices and accommodate
adding lower grade ore not included in the current reserves report. Despite this change, new stope development in the upper
higher-grade areas continues to advance and improvement in head grades should continue quarter over quarter. These
changes will be reflected in the production and cost guidance for this year and revision to the same for 2025 will be as follows:
Copper (000s pounds) 9,000 to 9,500
Gold (ounces) 7,500 to 8,500
C1 Cash Cost ($US)(1) $1.70 to $1.80
Note: Please see “Non-GAAP Financial Measures” at the end of this release. C1 cash cost per pound of payable copper
produced net of by-product (gold) credits and selling costs.
The planned concentrate shipment, originally scheduled for September, was postponed to October due to limited vessel
availability during the quarter. Since the company recognizes revenue upon shipment of the concentrate, this development will
cause all expected revenue from this period to be recorded in the fourth quarter, alongside the planned revenue for that period.

Concentrate Inventory
The number of shipments the Company can export in any given quarter depends on several variables some of which the
Company does not control, hence there may be an inherent variability in tonnes shipped quarter to quarter.

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 March 12, 2024, includes Proven and Probable mineral reserves of 828
thousand tonnes averaging 2.49% Cu, 2.20 g/t Au and a life of mine until Q1-2027. A full NI 43-101 technical report is available
on SEDAR+. For more information on the reserves estimate refer to SEDAR+ and on the Company’s website.
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.
