Monthly Mineral Production Survey, August 2023

Released: 2023-10-20

Data from the Monthly Mineral Production Survey and the Monthly Survey of Smelters and Metal Refineries are now available for August.

  Note to readers

The Monthly Mineral Production Survey estimates the production, shipments and inventories of Canada's leading minerals.

The Monthly Survey of Smelters and Metal Refineries covers smelters and metal refineries for a variety of base metals, including copper, lead, nickel and zinc.

Data are not seasonally adjusted.

Data for the previous two months are subject to revision based on late responses. Data for June 2023 and July 2023 were revised with this release.

Data for years prior to 2020 can be found on the Production of Canada's Leading Minerals page of the Natural Resources Canada website.

The value of shipments facilitates comparisons between mineral commodities as the units of measure of quantities produced or shipped vary drastically from one mineral to another (for example, iron in millions of tonnes versus diamonds in karats).
