Reserves and the “largest continent” are generalized: country and continent reserve rankings change with new discoveries, revisions, and extraction. The USGS MCS, BGS World Mineral Production, IEA critical minerals outlook and World Mining Data are the best single-document sources for year-by-year numbers. U.S. Geological Survey+2British Geological Survey+2
If you need country-level reserve tonnages, current annual production, and top-3 processing/refining companies for each mineral in a downloadable spreadsheet (CSV/XLSX) I can compile that next — it’s lengthy but fully doable; say “please make spreadsheet” and I’ll build it referencing a primary source (USGS & BGS) per row.
