Monthly Mineral Production Survey, November 2021

The Monthly Mineral Production Survey estimates the production, shipments and inventories of Canada's leading minerals. This survey covers several metallic minerals (including copper, gold, iron ore, lead, nickel, silver and zinc) and non-metallic minerals (including diamonds, gypsum, potash, and salt).

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 every three months, in the month ending the quarter.

Data are not seasonally adjusted.

Data for the previous two months are subject to revision based on late responses. Data for September and October 2021 have been revised with this release.

Data 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 since the units of measure of quantities produced or shipped vary dramatically from one mineral to another (for example, iron in millions of tonnes versus diamonds in carats).
