  • Caliguey is located 60 km northeast of Zacatecas city, 10 km east of the town of Villa de Cos.
  • Historically Caliguey was one of several salars in the region that produced sodium chloride from brines using evaporation ponds. Interestingly, the Mineral Resource Council of Mexico report brines containing up to 21,000 mg/L of Lithium collected from evaporation ponds at Caliguey as part of a sampling program in 1992. The three other brine samples collected during the program returned 12,000, 14,000 and 14,000 mg/L of lithium respectively.
  • Following the publication of the Mineral Resource Council report, Caliguey and surrounding salars, now predominantly held by the Company, were identified as potential targets for brine-hosted lithium exploration. Previous operators did extensive exploration work on the salar including a resistivity survey in 2010. Results indicated a depth to basement of around 30 metres; however, five reverse circulation holes drilled at Caliguey in 2011 failed to intersect basement. Depths for these holes ranged from 34 to 60 metres.
  • In 2009-2011, a grid pit sampling program akin those at Santa Clara and La Salada was carried out with some 1512 samples collected from over 300 pits. Assay results from this program returned potassium values from 0.22% to 11% with an average of 3.86%; lithium values ranged from 33 ppm to 2590 ppm with an average of 377 ppm.
  • 36 shallow surface sediment samples were collected in 2017 using a hand-held auger.  Potassium results are similar to historical data with an average of 3.38% potassium; lithium results are much higher with an average of 769ppm.
