[{"type":"text","content":"\n\n\n\nGold recoveries up to 95% achieved through conventional processes\n\nTSX-V Trading Symbol: HRC\nWebsite: www.helioresource.com\n\n\nVANCOUVER, Sept. 9 /CNW/ - Helio Resource Corp. ("Helio" or the\n"Company") (TSX-V: HRC) is very pleased to report the first metallurgical\ntestwork results from the Porcupine target at the SMP gold project.\n\n\nSummary results include:\n\n\n - Optimum circuit responses (% Au recoveries) as follows:\n - 94.8% by Whole Ore Flotation\n - 93.4% by Gravity Separation + Gravity Tailing Flotation\n - 91.9% by Gravity Separation + Flotation Concentrate Cyanidation\n - 89.1% by Gravity Separation + Gravity Tailing Cyanidation\n - 88.9% by Whole Ore Cyanidation\n - 22.0% by Gravity Separation\n - Bond ball mill work index of 15.7 (metric) - "moderately hard"\n - No preg-robbing activity detected\n - Low cyanide consumption\n - Tailings should be non-acid generating and free from environmentally\n deleterious elements\n\n\nOf particular note is that in one of the whole ore floatation tests,\nconducted on material with a relatively coarse grind size of 256 microns,\nrecoveries of 90.5% were achieved.\n\n\nThe results are in line with the very positive metallurgical results\npreviously obtained from the Kenge target, which showed gold recoveries of up\nto 96% could be achieved through conventional processes (see Company press\nrelease dated August 11, 2008).\n\n\nThe testwork was undertaken by SGS Lakefield Research Limited ("SGS") in\nOntario, Canada on a drill core sample from the Porcupine target. Tests\nincluded head grade analysis, mineralogical evaluation, comminution testwork,\ngravity separation, flotation, cyanidation (of whole ore, gravity tailing and\nflotation concentrate) and preliminary environmental testing. Further\ninformation and the full results of the metallurgical testwork are available\nin a report from SGS available on the Company's website at\nwww.helioresource.com/i/pdf/Porcupine-Metallurgical-Sep2009.pdf.\n\n\nA 50kg test sample was made up of the counterpart half-core from diamond\ndrill hole GPD4. The intercept chosen assayed 49.63m @ 3.3g/t Au from 52.76m,\nincluding 0.6m @ 33.2g/t Au from 66.1m and 1.8m @ 39.1g/t Au from 69.4m\n(Company press release dated July 21, 2008). If all high-grade samples in GPD4\nare cut to 15g/t Au, the in...
