“Core hole BC2001C intersected 67 meters (220 feet) averaging 1209 ppm Li and contained a high of 1710 ppm Li. Core hole BC2002C contained a high of 1070 ppm Li,” the press release states. “Occasional lighter coloured sediments seen in the core may indicate some leaching of soluble elements is occurring.”
Iconic added that water samples, highly diluted by added drill water, were taken from each core hole and analyzed for dissolved lithium. Of the four samples taken the high for dissolved lithium was 38 ppm.
“The highest water sample taken in all of Iconic’s previous drilling at Bonnie Claire, with the exception of one non-repeatable sample, was 4.1 ppm Li. As a result of these encouraging results, the water sampling was also taken in the RC drilling program. These samples were taken at rod changes after clearing the hole of drill water.”
Bonnie Clare is located within Sarcobatus Valley, which is approximately 30 kilometres long and 20 kilometres wide. Quartz-rich volcanic tuffs, that contain anomalous amounts of lithium, occur within and adjacent to the valley.
