[{"type":"text","content":"Vancouver, British Columbia--(Newsfile Corp. - June 28, 2017) - Iconic Minerals Ltd. (TSXV: ICM) (OTC Pink: BVTEF) (FSE: YQGB) (the \"Company\" or \"Iconic\") is pleased to announce that it has received results from its first shallow drill hole testing beneath a surface salt lithium anomaly at its Bonnie Claire project. BC1701 intersected low grade lithium brine beginning 20 feet (6 m) below the surface. Dissolved lithium values were highest in the 20-40 foot (6-12 m) interval at 29 ppm. Results of sediment sampling from the drilling have also been received and show increasing lithium values from 460 ppm in the 0-20 feet (0-6 m) sample to +1,000 ppm beginning 200 feet (61 m) below the surface and continuing to a total drill depth of 300 feet (91 m). Harris Exploration Drilling of San Diego, California drilled vertical hole BC1701 using Reverse Circulation (RC). The drill hole is located approximately 1.55 miles (2.5 km) south of hole BC1602 on the edge of present day mud flats. Composite 20 foot (6 m) sediment and brine samples were collected continuously down the hole. Sediments drilled consisted of siltstones with lesser sandstone and occasional thin clay beds. The exception is a 20 foot (6 m) thick clay bed which separates lower pH brines above from much more concentrated and higher pH brines below. The several sandstone beds intersected appear to correlate with higher lithium brine values. The 20-40 foot (6-12 m) and 60-80 foot (18-24 m) brine samples contained the highest lithium values and anomalous values continue to 140 feet (43 m). These intervals contain 5-15 feet (3-5 m) thick permeable sandy beds which appear to be aquifers. Shorter sample intervals may significantly increase lithium values. There also appears to be a direct relationship between lower pH and higher dissolved lithium values in the shallow brine. It is believed that lower pH groundwater is leaching lithium from the sediments as it migrates to a stratigraphic low where the lithium brine can concentrate over time. It also appears that these lithium brine pools are close enough to the surface that capillary action or \"wicking\" occurs and produces high lithium values in surface salts. Sampling of a 3.4 square mile (8.9 km2) surface salt grid sampling program to further define the extent of highly anomalous lithium values has been initiated. When results ...
