# Atico Produces 2.24 Million Pounds of Cu and 1,906 Ounces of Au in Third Quarter 2025 Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/atico-produces-2-24-million-pounds-of-cu-and-1-906-ounces-of-au-in-third-quarter--06ac4f49-d1e6-415e-90d4-2c26282ebd54 Original source: https://money.tmx.com/en/quote/ATY/news/5593792786309943/atico-produces-2-24-million-pounds-of-cu-and-1-906-ounces-of-au-in-third-quarter Publisher: tmx Original announcement: 2025-10-21T20:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Atico Mining Corporation - Ticker: ATY - Exchange: TSX - Region: Colombia - Primary commodity: Copper - Secondary commodities: Gold - Document categories: Production, Resource update - Extracted: 2026-09-17 11:31:30 UTC Narrative sentiment: -0.10 · Bearish ## Minestarters Atlas summary Atico Mining reported Q3 2025 production from its El Roble mine, with copper production decreasing 23% year-over-year to 2.24 million pounds and gold production decreasing 8% to 1,906 ounces. The company attributed the decline to a revised mine plan prioritizing lower-grade, previously excluded ore due to higher metal prices, which impacted copper head grade. Atico also provided revised 2025 guidance, projecting 9,000-9,500 thousand pounds of copper and 7,500-8,500 ounces of gold, with C1 cash costs between $1.70-$1.80 per pound. Reasoning: Q3 2025 production saw a year-over-year decline in copper and gold output, primarily due to a strategic shift to process lower-grade, previously excluded ore to maximize overall recovery, which impacted copper head grade. However, the company anticipates improved production in the next quarter and is conducting a drill program to increase reserves and mine life. - Positive factor: Strategic shift to incorporate lower-grade ore to maximize overall recovery - Positive factor: Anticipated production improvement in next quarter - Positive factor: Current drill program aims to increase reserves and LOM - Negative factor: Q3 2025 production decrease for copper and gold year-over-year - Negative factor: Copper head grade below budget - Negative factor: Postponement of concentrate shipment to next quarter Low confidence — this extraction should be reviewed alongside the original source.
