[{"type":"text","content":"Surge Battery Metals Reports Successful Results from Metallurgical Test Work for the Nevada North Lithium ProjectWEST VANCOUVER, BC / ACCESSWIRE / May 4, 2023 / West Vancouver, BC; Surge Battery Metals Inc. (the \"Company\" or \"Surge\") (TSXV:NILI)(OTC PINK:NILIF)(FRA:DJ5C) is pleased to report that in February 2023, the Company initiated Acid Leach Test Work and a Mineral Identification Study via Clay Speciation by X-Ray Diffraction on lithium bearing clays recovered from the maiden reverse circulation (RC) drill program of 2022 on its Nevada North Lithium Project (\"NNLP\").Acid Leach TestIn the first part of the program the laboratory facility of Kappes, Cassiday & Associates (KCA) received reverse circulation (RC) drill interval samples from the NNLP. The material was prepared and utilized for head analyses and scoping acid leach test work. Portions of as received and pulverized material from each composite sample were utilized for scoping leach test work. Minus 6.3-millimeter (as-received) material was utilized for water leach testing (ALT) and pulverized material (target 100% passing 0.106 millimeters) was utilized for acid leach testing.The results can be summarized as follows:The assayed heads and calculated heads had good agreement in this test program.The water leach tests of the composite samples did not show significant amounts of water-soluble lithium.Effective leaching of the lithium could be accomplished in 24 hours at ambient temperature with sulfuric acid consumptions ranging from 328 to 574 kilograms per metric tonne.Head screening test showed that Lithium values in the process feed were significantly reduced in the +0.075m fraction, thus overall feed values can likely be increased, and carbonate can be reduced by wet screening the feed material.Table 1 Li grades from KCA. Clay Speciation by X-Ray Diffraction (XRD) and Near Infrared (NIR) analysis.In the second part of the program similar reverse circulation (RC) drill interval samples from the Nevada North Lithium Project were delivered to SGS Natural Resources at Lakefield, Ontario (\"SGS\") for analysis by XRD and NIR.XRD is the preferred method for clay speciation, particularly swelling clays such as smectites. Clay mineralogy can provide a critical indicator of the presence of mineralization. The Semi-Quantitative analysis (RIR method) is performed ba...
