(\"\n \n Defense Metals\n \n \" or the \"\n \n Company\n \n \") (TSXV: DEFN) (OTCQB: DFMTF) (FSE:35D) is pleased to report favourable comminution results on multiple samples extracted from the Wicheeda deposit.  The data allows the design of the crushing and grinding plant that will be an integral part of the planned Wicheeda development. These data are essential inputs to the upcoming pre-feasibility study (PFS).\n \n \n \n \n \n \n \n \n \n Comminution, i.e., crushing and grinding, will be the first step in the processing of material mined from the Wicheeda deposit.  In the process, coarse, as-mined, rocks are reduced in size to sand-like particles, typically less than 1 mm in size, and suitable for upgrading by flotation or other means. Comminution usually accounts for a significant percentage of the energy demand, production cost and carbon footprint of a mineral processing plant.\n \n \n \n John Goode\n \n , Metallurgy Advisor, stated: \"Comminution tests on seventeen variability samples and a Master Composite show that the ore is soft, amenable to conventional grinding operations and has a low abrasion index. The recent results confirm, and expand on data obtained from a 30 t bulk sample taken in 2019.  The data show that a conventional semi-autogenous grinding (SAG) mill-ball mill circuit will work well and that grinding energy and supply cos...
