Monthly Mineral Production Survey, February 2023

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.

The Monthly Mineral Production Survey is conducted as part of the Integrated Business Statistics Program and the Minerals and Metals Production Statistics Program modernization initiative.

Data from the Monthly Mineral Production Survey and the Monthly Survey of Smelters and Metal Refineries are released every month, and a detailed review is released three times per year in the months of May, August and November.

Data are not seasonally adjusted.

Data for the previous two months are subject to revision based on late responses. Data for December 2022 and January 2023 have been 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).
