Build a public database of closed and abandoned extractive waste facilities carrying location, extent and waste volume, the operator or successor, and the quantities and concentrations of raw materials held -- backed by permit-file review, geochemical sampling and detailed characterisation.

Member States shall establish a database of the closed extractive waste facilities located on their territory, including abandoned extractive waste facilities, except for closed extractive waste facilities where the particular characteristics of the waste sites or geological conditions make the presence of potentially technically recoverable quantities of critical raw materials unlikely. That database shall contain information on: (a) the location, areal extent and waste volume, or where appropriate, the estimated volume, of the extractive waste facility; (b) the operator or former operator of the extractive waste facility and, where applicable, their legal successor; (c) the approximate quantities and concentrations of all raw materials contained in the extractive waste and, where available, in the original mineral deposit, in accordance with paragraph 7; (d) any additional information considered relevant by the Member State to enable the recovery of critical raw materials from the extractive waste facility.
