Lithium One Inc. (TSXV:LI) completed resource drilling for the Sal de Vida lithium and potash project at Salar del Hombre Muerto, Argentina. New drill results will contribute to a reclassification and expansion of the resource in a new resource estimate, as averaged lithium and potash grades are approximately 10% higher than those of the NI 43-101 resource previously announced.
As quoted in the press release:
The final six core holes complete a 28-hole, 3,255m program of drilling. Holes were drilled at an average 2.5km grid spacing and provided solid samples for direct porosity measurements and depth-specific brine samples for chemical analysis. In addition the Company drilled nineteen mud-rotary holes (totalling 1,932m), one of which is being used as the source of brine for the pilot evaporation ponds and plant and thirteen for short-term pumping test wells together with two reverse-circulation drill holes to fill in the sampling grid.
This final drill campaign identified brine with lithium (Li) grades of between 295-1,199 milligrams per liter (mg/L) and potassium (K) grades in the range of 3,249-13,680 mg/L. The averaged grades of the newly identified brine are 768 mg/L Li and 8,302 mg/L K, approximately 10% higher than the grades of the reported inferred resource. The chemistry of the brine also continues to be very favourable; the magnesium to lithium (Mg:Li) ratio averages 2.58 and the sulphate to lithium (SO4:Li) ratio averages 10.80. Given the consistent chemistry and higher grades within the existing resource area, these drill holes are expected to improve the overall resource grade.
