Mt Carbine Process Flow & Beneficial Reuse The material process flow at Mt Carbine focuses on the beneficial reuse of the products available from the LGS and historic tailings. EQ Resources Limited Annual Report 2022 15 1 Mt Carbine : Process Flowsheet The material process flow at Mt Carbine focuses of the beneficial reuse of the products available from the LGS and the historic tailings Oversize stockpiled for Quarry Sale Primary Crush & Screen Final Concentrate Exported Gravity Beneficiation Plant Stockpiled for Quarry Sales XRT Ore Sorter Plant Ore : Low Grade Stock Pile • 6-40mm barren by- product for sale in quarry as aggregate product • Production of 18 environmentally friendly profitgenerating quarry products – beneficial reuse promoting circular economy • -6mm inert manufactured sand for sale in quarry 6- 40mm Sorter feed -6mm tungsten sorter concentrate -6mm Fines feed 6- 40 mm Sorter By-product -6 mm Tailings • Sorter Feed undergoes 10x upgrade utilising X-Ray Technology and is transported to Gravity Plant for tertiary crushing prior to gravity processing Ore : Open Cut Mine • High-capacity Gravity Separation Tables separate heavy valuable tungsten material from the lighter-weight, barren tailings. • Production process has a calculated overall Tungsten recovery of 79.5%, for the crushing/screening/sorting and Gravity Plant • Processing facilities are designed for steady-state production of 1Mtpa • From crushing, materials are fed into dry and wet screeningfacilities currently in operation • 6-40mm ore material is fed into the 2x Tomra XRT sorters for upgrading • -6mm fines are directly pumped in a wet slurry to Gravity Plant for beneficiation. • Accelerated Production Continues • Mt Carbine Produces a premium Ammonium Paratungstate product that contains 50% WO3 • Tungsten concentrate currently produced at site is loaded into bulk bags, sealed and sold ex-gate at Mt Carbine for export. • Existing infrastructure, pit and 430m decline allows cost- and time-efficient start of OC and UG works that will feed high-grade ore into production from day 1. • OC Strip Ratio = 5.11 over LOM • Currently 12 Mt low grade historical stockpile and 2Mt historical tailings resource is feeding production. • Free-dig mining of stockpile material is directly fed to crushing and screening facilities for sizing prior to downstream beneficiation • Oversize, uneconomical rock is stockpiled for beneficial reuse through quarry sales. • Used in the building of regional breakwaters, boat ramps and infrastructure development WO3 Concentrate
