These units are hostedin a much thicker gently dipping sequence mainly composed offine-grained sediments affected by syn and post depositionalfaulting.Processing plants and other available facilitiesThe planned site layout includes a concentrator to beneficiatethe primary ore, a chemical plant to produce boric acid andlithium carbonate, paste plant, water and waste treatmentplants, surface waste storage (dry stack), railroad spur andwarehouses for product storage and loading/unloading, andoffice buildings.Power sourceConnected to the national electric grid.
