Capstone Copper Halt Production at Mantoverde Operation

SEATTLE (Scrap Monster): The output of sulphide copper at the Mantoverde mine in Chile has been temporarily hampered by a ball mill motor failure, according to Vancouver, Canada-based Capstone Mining.

On August 24, 2025, the site reported that one of its two ball mill electrical drive motors had failed. Over the course of the following few days, the on-site staff promptly replaced the damaged motor with the spare. However, the second ball mill drive motor failed at the location. Because there were no extra spare parts on hand, this caused a brief halt in manufacturing.

It is estimated that the ball mill motor repairs will take about four weeks. During this time, the business anticipates continuing to run at about half capacity. In order to accommodate the ball mill outage, the business also intends to reschedule plant maintenance that was initially scheduled for later in September.

According to a press release from the company, it is anticipated that the temporary production suspension will affect Mantoverde's output by between 3,000 and 4,000 tons of copper concentrate. It further stated that more updates would be given when they become available.
