08:36 AM EDT, 10/08/2025 (MT Newswires) -- Amerigo Resources ( ARREF ) , which saw its shares jump 3.3% to 52 week highs yesterday, announced Wednesday operational results for the quarter ended September 30, 2025 from Minera Valle Central, the company's 100% owned operation located near Rancagua, Chile, which was impacted by lower fresh tailings throughput following an accident at the El Teniente mine.

Among highlights, ARG cited Q3-2025 copper production of 14.6 million pounds; and said 2025 copper production is estimated to be 2% to 5% below guidance, while cash cost guidance remains in place. The company added it is "positioned to eliminate remaining debt" in Q4-2025, while US$3.5 million was returned through dividends in Q3-2025.

The company in a statement said operational results during Q3-2025 were impacted by lower fresh tailings throughput following an accident at the El Teniente mine. ARG noted MVC did not receive fresh tailings for 10 days in August while El Teniente's mine operations were fully suspended. It said El Teniente's operations continue to ramp up under the Safe and Progressive Restart of Operations Plan, but fresh tailings throughput has not yet returned to pre-accident levels. Despite this dynamic situation, MVC's daily production has remained stable since the last week of August, it added.

"Utilizing the tremendous flexibility of MVC's processing plant, our team has done an exceptional job increasing the processing of historic tailings and adjusting plant performance to minimize the continued impact from lower fresh tailings throughput. MVC's production results were heavily impacted in August, but MVC's September output was closely aligned with its original monthly production budget," said Aurora Davidson, Amerigo's President and CEO.

"Notwithstanding MVC's agile response, the August production shortfall will likely prevent Amerigo from meeting its original annual production guidance of 62.9 million pounds of copper. We currently expect to produce between 60 and 61.5 million pounds of copper in 2025, which is 2% to 5% lower than our original guidance. Amerigo's molybdenum production and cash cost guidance remain in place."
