(1)Approximate size considers both the production facilities and the mine for the Salar de Atacama. Mining areas are those authorized for exploitation by the environmental authority and/or Sernageomin.
(2)Weighted average age and gross book value correspond to production facilities, excluding the mine, for the Salar de Atacama.
We directly or indirectly through subsidiaries own, lease or hold concessions over the facilities at which we carry out our operations. Such facilities are free of any material liens, pledges or encumbrances, and we believe they are suitable and adequate for the business we conduct in them.

(1)Lithium carbonate is produced from concentrated lithium chloride solution obtained at the Salar de Atacama and processed at our Lithium Chemical Plant near Antofagasta. Potassium salts include synthetic sylvinite produced in the plant and other harvested potassium salts (natural sylvinite, carnallites and harvests from plant ponds
