[{"type":"text","content":"Vancouver, British Columbia--(Newsfile Corp. - December 15, 2016) - Iconic Minerals Ltd. (TSXV: ICM) (FSE: YQGB) (OTC Pink: BVTEF) (the \"Company\" or \"Iconic\") is pleased to announce that it has received very encouraging initial lithium leaching results from sediments drilled in BC1601 at its Bonnie Claire project. Three samples from different elevations of the 1,560 feet (475 m) thick, continuously mineralized section of fined grained sediments show leach recoveries of 98, 93 and 89 percent Li, leaching with dilute acid. The lithium in the brine leachate appears to be lithium chloride, which is how lithium occurs in Clayton Valley brines. Early analysis of the sediments including geochemical and x-ray diffraction (XRD) results indicate the lithium is possibly occurring as lithium carbonate. Sample depths, lithium content of the original sample, lithium content of the leachate, and total recovery are shown in the table below. Sample Description Sediment Assay Li (ppm) Leachate Assay Li (ppm) Recovery (%) BC1601 440-460' 1420 1390 98 BC1601 780-800' 1220 1130 93 BC1601 1220-1240' 2550 2260 89 Samples were leached with dilute hydrochloric/nitric acid and the leachate analyzed by Inductively Coupled Plasma (ICP) by ALS Minerals of Reno, Nevada. The sediment assays average 1,153 ppm Li over the 1,560 feet (475 m) depth of the drill hole with the highest value being 2,550 ppm Li. The lithium-rich sediments probably continue below the currently drilled depth. XRD results show the sediments, dominated by very fine grained particles, are made up of common volcanic minerals and only minor clay minerals. Further leach tests are under way using only deionized water. Additional metallurgical testing is planned to determine if either bulk mining and heap leaching or in-situ leaching may be feasible for lithium recovery at Bonnie Claire. Brine assays from both BC1601 and 1602 have now been received. Analysis was done by Western Environmental Testing Laboratory of Sparks, Nevada. A highly anomalous brine sample was taken at 1,500 feet (457 m) in BC1601 which assayed 132 ppm Li. Although the lithium content of other brine samples from BC1601 were low, the assay from 1,500 feet is encouraging enough to warrant additional brine drilling. Results from BC1602 had a high Li value of 19 ppm. The results show that the Bonnie Claire project has the ...
