When mineralising fluids pass through it, large volumes of fluorspar can replace the original rock • Three drill to resource ready targets – Horseshoe, Mammoth and Big Jim all show scale and grade to achieve mineral resource estimate • Extensive alteration and other mineral occurrences to be followed up.
