According to a latest update from the United States Geological Survey, In August 2023, mine production of recoverable copper in the United States was 89,900 metric tons (t). The average daily mine output was 2,900 t, a decrease of 4% compared with that in July and 12% less than that in August 2022. Year-to-date mine production through August 2023 was 728,000 t, a decrease of 12% from that in the same time period in 2022. Production declined at a majority of US copper mines in 2023 because of reduced copper ore grades, lower mining rates, and (or) unplanned maintenance. The average daily refinery production was 2,180 t, 5% lower than that in July and a decrease of 16% compared with that in August 2022. Year-to-date refinery output through August 2023 was 595,000 t, a decrease of 6% relative to the same time period in 2022.
