  • The 30 day test showed no drawdown in piezometers located above and at the top of the brine body. The dynamic level in the pumping well showed 40 m of drawdown over the test.

  • An updated resource estimation is underway and will incorporate the significantly greater drilling depths of the Phase III program just completed

  • Preliminary design of production wellfields is underway for the Feasibility Study, using the results of the long-term CAU07 and CAU11 pumping tests.

Orocobre Managing Director and CEO, Martín Pérez de Solay, commented:

“The CAU07 test results confirm the excellent characteristics of the NW Sector for future brine production, both in terms of lithium concentration and pumping characteristics. The joint venture is currently conducting an update of the project resource estimate with results from the recently completed drilling, concurrently with preliminary design of production well fields for the project Feasibility Study. We look forward to providing this information to shareholders once it is completed.”
