[{"type":"text","content":"Mawson Reports Excellent Metallurgical Liberation Of Both Gold And Cobalt From Rajapalot, FinlandVANCOUVER, CANADA / ACCESSWIRE / September 11, 2019 / Mawson Resources Limited (“Mawson”) or (the “Company”) (TSX:MAW)(Frankfurt:MXR)(OTC PINK:MWSNF) reports on gold and cobalt liberation studies from five composite drill hole samples from the Raja and Palokas inferred mineral resource project areas. The qualitative study aimed to liberate and concentrate gold and cobalt minerals via enhanced gravity recovery. Concentrates were subsequently analyzed by Mineral Liberation Analysis to establish the geochemical, textural and mineralogical variability within mineralized domains with a view to establish a viable metallurgical flow sheet. This is the first liberation study for cobalt from the project as well as the first project-wide liberation work for gold.Key Results:Greater than 90% of gold and cobaltite were liberated and concentrated via enhanced gravity recovery into heavy concentrates, with only moderate grinding, indicating that mineralization is amenable to low-impact and energy efficient gravity pre-concentration;Gold is predominantly in the form of native gold and occurs as single coarse irregular shaped grains (95% of mass);Cobaltite is the dominant cobalt mineral. The high density and coarse grainsize of the cobaltite make it an ideal candidate for gravitational separation in a future process flowsheet;Mr. Michael Hudson, CEO states: “The first stage of any metallurgical study is to assess the mineral liberation characteristics of the target minerals (gold and cobalt) so that processing methods to separate them from waste minerals can be designed. These initial qualitative results are very encouraging, and indicate native gold and cobaltite are amenable to low-impact and energy efficient liberation followed by gravity pre-concentration. Work under the BATCircle research program continues for the Rajapalot project with batch flotation and leach tests planned next.”Five samples, one from Palokas and four from the Raja prospect, were selected based on representative gold and cobalt grade and host rock composition for qualitative mineral liberation test work. Qualitative liberation of gold and cobaltite into gravity concentrates was high, exceeding 90 per cent when ground to a median grai...
