04:59 PM EST, 11/18/2025 (MT Newswires) -- Atico Mining ( ATCMF ) after close Tuesday said it swung to a third-quarter loss and negative sales mainly due to a delayed shipping vessel in Colombia.

The company lost US$4.13 million in the period, compared with a profit of US$1.16 million a year ago. Per share figures were not given.

For the quarter ended Sept. 30, the company had negative sales of US$1.27 million, compared with revenue of US$24.6 million a year prior. FactSet expected US$19.2 million.

Atico's El Roble mine produced 2.3-million pounds of copper and 1,847 ounces of gold in the quarter, with a cash cost of US$2.74 per payable pound of copper. Copper production fell 23% and gold production dropped 11% from the same quarter in 2024, "primarily due to lower ore throughput as well as lower copper head-grades," the company said.

"Third-quarter results were impacted by a delayed arrival of the shipping vessel to the port in Colombia, which left all concentrate in inventory as of Sept. 30, thus pushing sales into the subsequent period. The sale of said concentrate occurred in October and will be recognized in Q4 2025 in addition to our Q4 production shipment," Chief Executive Fernando Ganoza said.

"We expect further gradual improvement in production next quarter due to higher copper grades, as our mine plan continues to increase feed from the upper higher-grade zones," he added.

Atico shares closed unchanged at $0.20 on the TSX Venture Exchange.
