(1) Approximate size considers both the production facilities and the mining, exploration, miscellaneous and general purpose leases for Mount Holland, where the mine, concentrator and NPI facilities reside, and the Kwinana refinery. Nominal production capacities are for the whole project (SQM+Wesfarmers share)
(2) Weighted average age and gross book value correspond to SQM’s 50% share of production facilities for Mount Holland assets and Kwinana refinery.
