Abstract
Manganese is a critical metal for modern economic development. Over 85% of manganese is used in the production of steel, where, as a desulphurising agent, it is an essential additive in all steelmaking, and as an alloying agent it makes a range of specialty steels. Additionally, it has significant uses in fertilizer, animal feed, rubber, glass, unleaded gasoline, ceramics, and paints. Currently over 80% of manganese ore comes from a few mines in Africa and Australia, but its production is facing two potential paradigm shifting developments over the next decade: the potential extraction of manganese nodules from the ocean floor; and within the transition to a green economy as a battery component for electric vehicles.
Herein we present the first national inventory of Canada’s manganese occurrences in 90 years. While Canada has no current production, it does contain many occurrences, though most are too small to be viable operations. Presently, the deposits most suitable for mining are in the Woodstock area, New Brunswick. Not only are these relatively large tonnage and high grade, their mineral composition makes them more suitable for electric vehicle batteries than most current mines or in the future manganese nodules.

Description of the data and file structure
Rogers_et_al_Mn_Supplemental_data_1.csv contains the tabulated supplemental data 1 from Rogers et al. (in press) as a CSV (Comma-Separated Values) plain text file that records the location by country, region and geographic coordinates, as well as a link to their mindat.org site, for select major manganese mines to complement Figure 1.
Table structure:
Mine name - given name for highlighted mine or district
Country - country of occurrence
Region - region name of occurrence; blanks are given as null
Latitude N - geographic coordinate for latitude in decimal degrees north (WGS84)
Longitude E - geographic coordinate for longitude in decimal degrees east (WGS84)
Link to additional mine data - URL for the Mindat.org entry on the mine
Rogers_et_al_Mn_Supplemental_data_2.csv contains the tabulated supplemental data 1 from Rogers et al. (in press) as a CSV (Comma-Separated Values) plain text file that records additional data and link to provincial or territorial mineral occurrence database entries for the major Canadian manganese occurrences presented in Table 1 and on Figure 2.
Table structure:
ID # - designated identification number to link items between Rogers et al. (2025) Table 1 and Figure 2. Order is by NTS map sheet (broadly east to west and south to north).
Deposit name - given name for the occurrence
Province/Territory - province or territory of the occurrence
Local region - geographic/geological region of the occurrence; blanks are given as null
Provincial or territorial mineral occurrence unique identifier - provincial or territorial mineral occurrence database given unique identifier, if applicable; blanks are given as null
NTS map sheet number - National Topographic System (NTS) grid 1:50 000 map sheet code
Latitude N - geographic coordinate for latitude in decimal degrees north (WGS84)
Longitude W - geographic coordinate for longitude in decimal degrees west (WGS84)
Depositional age - interpreted formation age of the occurrence following the International Commission on Stratigraphy's International Geological Time Scale (https://stratigraphy.org/chart/); value at the Eon, Era, Period, Epoch or Stage level depending on occurrence knowledgebase
Age range upper limit/ Ma - upper age in millions of years ago of the identified age as given on the International Chronostratigraphic Chart (v2024-12)
Age range lower limit/ Ma - lower age in millions of years ago of the identified age as given on the International Chronostratigraphic Chart (v2024-12)
Commodities - primary and secondary commodities link with the occurrence
Deposit Type - interpreted deposit type of the occurrence
Provincial or territorial mineral occurrence database link - URL for the provincial or territorial mineral occurrence database entry, if applicable; blanks are given as null
