Monthly Mineral Production Survey, September 2025

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 July and August 2025 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).

On November 20, 2025, the tabular displays were updated. The tables are listed below:

• Table 16-10-0019-01: Production of metallic minerals in quantities, monthly
• Table 16-10-0019-02: Production of metallic minerals in value, monthly
• Table 16-10-0020-01: Production of non-metallic minerals in quantities, monthly
• Table 16-10-0020-02: Production of non-metallic minerals in value, monthly
• Table 16-10-0021-01: Value of shipments of metallic and non-metallic minerals, monthly
• Table 16-10-0021-02: Value of shipments of critical minerals, monthly
