Lithium Mineral Resource Summary (effective date July 11, 2012)

Cut-off 354 mg/l
Description Brine (m3) Average Lithium Concentration (mgéL) Lithium Carbonate Equivalent (tonnes) Lithium
Measured Resources2,3,4,5,6 9.14 x 108 630 3,039,000 576,000
Indicated Resources2,3,4,5,6 2.89 x 109 570 8,713,000 1,650,000
  1. 1.Ratios of lithium to other metals include: K:Li of 8.2, Mg:Li of 2.4, B:Li of 1.6, SO4:Li of 28.5.
  2. 2.LCE is calculated based the following conversion factor: Mass of LCE = 5.323 x Mass of lithium metal
  3. 3.The conversion is direct and does not account for estimated processing losses.
  4. 4.The values in the columns on Lithium Metal and Lithium Carbonate Equivalent above are expressed as total contained metals.
  5. 5.Mineral Resources have a cut-off grade of 354 mg/L of lithium.
  6. 6.Mineral Resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all of any part of the mineral resource will be converted to mineral reserves.
