Comments on the reserve resource information

  • RESERVES ARE CONSIDERED SUFFICIENT FOR CURRENT PRODUCTION LEVELS, BUT NEIGHBORING LAKE SHALA IS CONSIDERED THE PRIME SOURCE OF BRINES FOR FUTURE EXPANSION. RESOURCE ESTIMATE INCLUDES NEIGHBORING LAKES ABIYATA, SHALA, AND CHITU.

Comments on development

  • ECON.COM: SODA ASH PLANT HAS BEEN IN OPERATION SINCE 1990 AND HAS A 20,000 METRIC TON 'ER YEAR DESIGN OUTPUT CAPACITY.
