| "important_limitation": "This is not a complete global inventory of every mine. The source dataset was constructed around mines reported as active at some point between 2000 and 2017, and the original authors explicitly state that it does not cover all existing mining locations worldwide. Treat this as a footprint map of the sites that were identified and mapped, not an exhaustive census.", |
