Atico Mining Corporation (TSX-V: ATY) (OTCID: ATCMF) announced its financial results for the three and six months ended June 30, 2026, posting income from mining operations of $2.1 million and a net loss of $0.2 million for the quarter. Production for the quarter at Atico’s El Roble mine totaled 2.1 million pounds of copper and 1,465 ounces of gold in concentrate at a cash cost⁽¹⁾ of $3.48 per payable pound of copper (net of gold credits) ⁽¹⁾⁽²⁾.

Fernando E. Ganoza, CEO and Director, stated: “During the second quarter, we experienced a temporary decrease in gold output alongside a significant appreciation of the Colombian Peso. These simultaneous developments impacted our operational costs and net earnings for the period. While development at the mine continues to advance quarter-over-quarter, we faced operational bottlenecks that temporarily delayed our primary objectives during the quarter. We expect to resolve these challenges and deliver improvements over the first half of the year in the following quarters.”

Second Quarter 2026 Financial Highlights

• Revenue for the quarter decreased 18% to $17.4 million from $21.1 million in Q2-2025, reflecting higher metal prices and greater sales volume. Copper and gold accounted for 69% and 31% of the 4,989 (Q2-2025 – 7,842) dry metric tonnes of concentrate sold during Q2-2026.
• The average realized price per metal was $6.26 (Q2-2025 – $4.47) per pound of copper and $4,417 (Q2-2025 – $3,406) per ounce of gold.
• Net loss was $0.2 million for the quarter, compared with net income of $2.7 million in Q2-2025.
• As of June 30, 2026, the Company had reduced its working capital deficit to $12.1 million from $20.2 million on December 31, 2025. The Company also had $6.9 million in long-term loans payable (December 31, 2025 – $6.7 million) and $2.7 million in long-term arbitration award payable (December 31, 2025 – $Nil), both due beyond one year.
• Cash costs⁽¹⁾ in Q2-2026 were $228.90 per tonne of processed ore (up 39% from Q2-2025 – $164.26) and $3.43 per pound of payable copper produced (net of gold credits)⁽¹⁾⁽²⁾ (up 98% from Q2-2025 – $1.73). The increase in cash cost per tonne primarily reflects the strengthening of the Colombian peso against the U.S. dollar which increased production costs when translated into U.S. dollars. Cash costs were also impacted by higher mining costs associated with higher stope preparation and ground support costs as mining operations transition to the upper zones of the mine. The increase in cash costs per pound of payable copper produced was primarily driven by higher production costs, as mentioned above, and lower gold by-product credits because of lower head grades during Q2-2026.
• Cash margin was $2.83 (Q2-2025 – $2.74) per pound of payable copper produced⁽¹⁾, up 4% from Q2-2025, as higher realized copper prices in Q2-2026 were largely offset by higher cash costs per pound noted above.
• All-in sustaining cash cost per payable pound of copper produced⁽¹⁾⁽²⁾ in Q2-2026 increased to $5.82 from $3.91 in Q2-2025, mainly because of higher production costs driven by the strengthening of the Colombian peso against the U.S. dollar, and the lower gold by-product credits (as described above).
