American Salars Lithium Inc. Starts Sampling at 100% Owned Brazilian LCT Pegmatite Project
AMERICAN SALARS LITHIUM INC announced that it has commenced a Phase 2 sampling program on its 100% owned, highly prospective 18,083 Hectares (180 sq km) Hardrock LCT ('Lithium-Cesium-Tantalum') Pegmatite Project including Rare Earth Elements ('REEs') and Critical Minerals (the 'Jaguaribe Project'). The Jaguaribe Probject is located in the Jaguaribe/Solonopole region in the State of Ceara, in Northern Brazil and hosts multiple extensive Lithium and REE bearing pegmatite dykes that have returned initial Phase 1 sample discoveries of up to 3.72% Li2O, 2.15% Li2O and 1.58% Li2O as well as 554.5 ppm of Cesium,135 ppm of Tantalum, 177 ppm of Niobium. One sample showed high values for Rubidium (>10,000ppm); Tin (675 ppm) and Zinc (387ppm). The initial phase 1 exploration program revealed multiple long and wide pegmatite dykes that measure up to 30 meters in width and up to 300 meters in length that are largely unexplored. The Jaguaribe Property covers historic artisanal mining sites previously mined for lithium, coltan (tantalum and niobium) and tin.Initial sampling of the Jaguaribe Pegmatites returned Spodumene bearing pegmatite samples that graded up to 3.72% Li2O as well as Rare Earth Elements.Phase 2 sampling will test multiple additional LCT Pegmatite targets.Ideal project location - Historical Pegmatite Province Brazil.4-hour drive on paved roads to port and international airport (Fortaleza). The topography, land use and vegetation at Jaguaribe Property is well suited for exploration activities.Arid, sparsely populated farmland, no rain forest.Northern Brazil provides shipping routes and deep-water ports to North American and European battery chemical markets.Multi elements ICP analysis (55 elements) of 13 pegmatites sampled across the Jaguaribe Project, returned: Lithium, Rubidium, Tantalum and Niobium. Of the 13 samples, one (VM-EJ-R-01) is mineralized with Lithium at (3.72% Li2O), a normal occurrence, because it was the first geological reconnaissance work carried out on the Project. The presence of Li bearing Lepidolite and Spodumene minerals were observed in the pegmatites during the initial fieldwork.Pegmatite VM-EJ-01 is an LCT (Lithium-Cesium-Tantalum) pegmatite, in addition to samples of 3.72 Li2O, anomalous values of 554.5 ppm of Cesium and 135 ppm of Tantalum were recorded, accompanied by 177 ppm of Niobium and high values for Rubidium (>10,000ppm); Tin (675 ppm) and Zinc (387ppm). Initial fieldwork also detected two additional pegmatites with 2.15% and 1.58% Li2O, respectively, which led to the exploration and acquisition of the 10 claim blocks that make up the Jaguribe Property.Geochemical Characteristics of Pegmatites, Jaguaribe Project, Ceara, BrazilA multi-element analyse was conducted at the SGS laboratory for 58 elements including REE, from 12 samples from the Jaguaribe Project. These samples were analyzed by the ICM90A method: determination with fusion in sodium peroxide-ICP OES/ICP MS.Geochemistry of the Pegmatites samples from the Jaguaribe Project area, was compared with the standard sample or standard analysis provided by the SGS laboratory, with the common elements and their contents in an LCT-type Pegmatite (Lithium, Cesium and Tantalum). The pegmatite from the VM-R-01 Pegmatite sample, which contained Lepidolite and a content of 1.54% Li2O, shows a strong geochemical correlation with the standard sample, in terms of the contents of Li, Cs, and Ta, the latter being much higher (135 ppm Ta) than the Ta content of the SGS standard sample (18 ppm Ta). The VM-R-1 sample also shows a correlation with the SGS standard, in terms of Rb, Nb, Sn and P. Other pegmatite samples from the Jaguaribe Project, namely VM-R-6 and VM-R-7, are iron enriched and present less marked correlations, in relation to the contents of the standard sample only in the elements Li, Rb and Ba, although they show anomalous geochemical values of Cs. The results of the VM-R-8 and VM-R-10 analyses show a good correlation with the results of the SGS standard sample, regarding the contents of Rb, Ba, Cs, Ta, Nb and P, but the Li levels fell, respectively, to 110 ppm and less than 10 ppm. This sharp drop in the Li levels of these samples is mainly due to the leaching of Li minerals by surface waters, notably Spodumene, a phenomenon observed in most of the pegmatites in the region, whose Li levels increase substantially in the subsurface in mining pits, in the companies' research excavations and mainly in drill holes.
