 $134.23 per ton, depending on the location and market. The following table summarizes our mineral resources by major commodity group and geographic region as of December 31, 2024:

Our inferred mineral resources have been estimated on the basis of limited geologic evidence. Mineral resources, that are not mineral reserves, do not have a demonstrated economic viability at this time; however, of the 249.1 million tons of inferred mineral resources, 200.5 million tons or 81% are attributable to 20 active mining operations.
