[{"type":"text","content":" VANCOUVER, British Columbia, Nov. 28, 2019 (GLOBE NEWSWIRE) -- Independence Gold Corp. (TSX.V: IGO) (\"Independence\" or \"the Company\") is pleased to the announce results from an Early Stage Metallurgical Study (“ESME”) carried out on auriferous vein material collected from the Sullivan Ridge Target at the Merit Property (“the Property”), British Columbia. The study, comprised of two composite vein samples recovered 99.5% and 96.6% gold, respectively, through a three-stage process of gravity separation, flotation and leaching, indicating favourable mineralogy for further exploration. Sample Selection and PreparationComposite samples composed of chalcedonic quartz were collected from two separate veins at the Sullivan Ridge Target. These veins yielded gold assay values up to 9.5 grams per tonne (“g/t”) from samples collected earlier in the season (see news release dated November 4th, 2019) and are considered representative of the Property. Samples were submitted to SGS Labs in Burnaby for testing. They were initially crushed to 100% passing 10-micron mesh, then each sample was blended and rotary split into two-kilogram test charges for the metallurgical testing. A 100g sub-sample was also separated using a riffle splitter and submitted for chemical head assays including gold, copper and total sulphur, as well as for head mineralogy study. Head ResultsThe following table shows the assays results for both samples and appear to show some level of “nugget” distribution in the samples as expected. Sample Au (g/t) Au-Duplicate (g/t) Au Average (g/t) Ag (g/t) Cu % S % ESME 1 0.59 0.68 0.64 145 <0.01 0.03 ESME 2 7.29 7.01 7.15 11.0 0.02 0.03 The mineralogy of the two samples were studied using QEMSCAN Particle Mineral Analysis (PMA), and indicated the main sulphides present are pyrite and marcasite, with copper being mostly native. Gravity SeparationA single gravity separation test was completed on each composite to evaluate the potential for gravity recoverable gold and silver using a Knelson concentrator. The concentrate was submitted for assaying and the tailings used for floatation testing. Gravity methods managed to recover 50.7% gold and 66.6% silver in ESME 1, and 62.2% and 38.8% silver in ESME 2. Floatation TestworkA single test was conducted on each of the gravity tailings to assess further recoverability of gold and ...
