[{"type":"text","content":"Ero Announces Result of Year-Long Value-Creation Initiative at Xavantina, Commences First Gold Concentrate Sales in Q4 2025\n\n\n\n VANCOUVER, British Columbia, Nov. 04, 2025 (GLOBE NEWSWIRE) --\n \n Ero Copper Corp. (TSX: ERO, NYSE: ERO)\n \n (\"Ero\" or the “Company”) is pleased to announce the results of a year-long effort to create additional value from its Xavantina Operations, located in Mato Grosso State, Brazil as well as an update of its National Instrument 43-101 (“NI 43-101”) compliant mineral reserve and resource estimate. The mineral reserve and resource estimate for the Xavantina Operations incorporates drilling activities and mining depletion on the property through June 30, 2025.\n \n\n\n HIGHLIGHTS\n \n\n\n\n Beginning in late 2024, the Company launched a transformational value-creation initiative at its Xavantina Operations, which included comprehensive sampling, metallurgical testing, material characterization, and commercial negotiations to capture value from stockpiled gold concentrates produced in small but high-grade quantities since processing operations began in 2012.\n \n\n\n\n To date, the Company has sampled approximately 20% of the total stockpile volume of approximately 60,000 cubic meters, resulting in a maiden inferred mineral resource estimate of approximately 29,000 ounces (24,000 tonnes at 37.4 grams per tonne (\"gpt\")) in high-grade, marketable gold concentrate within the sampled volume.\n \n\n\n\n In October 2025, the Company successfully completed initial shipments of approximately 3,000 tonnes of gold concentrate and expects to ramp up shipments through year-end, selling approximately 10,000 to 15,000 tonnes during Q4 2025.\n \n\n\n\n The Company entered into a sales contract for expected 2025 gold concentrate volumes with an expected net payability, prior to streaming adjustments and after deductions, treatment and refining charges, ranging between 90% and 95% based on the final concentrate grade, port of destination, and the prevailing gold price at the time of sale. Operating costs for excavating, drying, loading, transportation and seaborne freight are expected to be approximately $300 to $500 per ounce.\n \n\n\n\n Additional sampling campaigns are underway to quantify the remaining gold concentrate density and grade. The Company expects to complete sampling...
