Boab Metals Limited report that the Metallurgical and Geotechnical testwork programs for the Sorby Hills Definitive Feasibility Study ("DFS") have commenced. The DFS metallurgical testwork program has been carefully designed to investigate and define the optimal processing parameters and associated metallurgical performance of ore to be mined from Sorby Hills deposit. A total of 28 metallurgical drill holes for 2,116m have been completed from which master, schedule and variability composite samples have been selected and submitted to ALS Metallurgical Laboratories in Perth. In addition to comminution (crushing and grinding), flotation and tailings testwork, a primary objective of the metallurgical program will be to further investigate the incorporation of a Dense Media Separation ("DMS") plant into the processing flowsheet as a way to add value to the Sorby Hills Project. Previous metallurgical testwork conducted by the Company has demonstrated that the inclusion of a DMS in the flowsheet would potentially allow for the economic incorporation of lower grade ore into the production schedule by enhancing feed grade (2.7x for Lead and 2.4x for Silver - ASX release 30 April 2020) and increasing ore throughput. The DFS will build on this body of work through a combination of bench scale and pilot scale testwork programs. Lead-Silver concentrate samples and specifications generated from the metallurgical testwork program will support discussions with Offtakers over the coming months.
