Lithium Remains in Record High Demand Based on Booming EV Revolution - Seite 2

Tonnages are rounded off to the nearest 1,000.  Cutoff grade: 500 mg/L lithium, but no laboratory results were less than the cutoff grade.

The conversion used to calculate the equivalents from their metal ions is based on the molar weight for the elements added to generate the equivalent. The equations are Li x 5.3228 = lithium carbonate equivalent and K x 1.907 = potassium chloride equivalent.

The reader is cautioned that mineral resources are not mineral reserves and do not have demonstrated economic viability.
 

The resource estimate was prepared in accordance with the requirements of National Instrument 43-101 and uses best practice methods specific to brine resources, including a reliance on core drilling and sampling methods that yield depth-specific chemistry and effective (drainable) porosity measurements. The resource estimation was completed by independent qualified person Mr. Michael Rosko, M.Sc., C.P.G. of the international hydrogeology firm E.L. Montgomery & Associates (M&A).

The resource is defined over a 3.9 square kilometer footprint using results from core drilling and depth-specific packer sampling. In addition, the brine was also sampled during short-term pumping tests. The new Measured and Indicated Resource was derived from two polygons surrounding core holes drilled to depths of 401 and 281 meters (m). Large-diameter rotary holes were drilled to adjacent to both core holes, each to a depth of about 400 m. The spacing between the two pairs of core/rotary holes is approximately 2.1 kilometers.

The chemistry of the Hombre Muerto North brine is judged to be very favorable. Brine density and the ratios of magnesium and sulfate to lithium for the combined measured and indicated resource are given below:

• Density of the brine from depth-specific samples at the core holes ranged from 1.19 to 1.23 grams per cubic centimeter (g/cm^[3])
• Average Magnesium/Lithium ratio is 2.6 to 1
• Average Sulfate/Lithium ratio is 11.7 to 1

Based on the geologic model, approximately 33% of the resource is hosted by sand and silty sand units, 28% by interbedded halite, sand and silty sand and 39% sandy conglomerate.

The total contained lithium and potassium values are based on measurements of effective (drainable) porosity distributed throughout the aquifer volume that defines this resource. This method of porosity determination is designed to estimate the portion of the total porosity that can theoretically be drained by pumping; however, these estimates may differ from total extractable quantities. The drainable porosity is different for each hydrogeologic unit, but the average ranges from about 8 to 11% based on laboratory results.  Read this and more news for NRG Metals at: http://www.financialnewsmedia.com/news-ngz/
