[{"type":"text","content":"Sun River Advances Tailings Project in El Oro Mexico(via TheNewswire)\n \n \nVancouver, British Columbia / TheNewswire / June 13, 2019 - Candente Gold Corp. (TSXV:CDG) (\"Candente Gold\" and/or the \"Company\") is pleased to advise that Sun River Gold has reported very positive recoveries from metallurgical testing of samples from the tailings deposit and is moving the project forward by negotiating the purchase of land for the new processing area and also working on the application for change of use of land for the area where the tailings are currently located.\n\n \n \nSun River Gold (\"SRG\") reports that it has concentrated on flotation test work as the most promising process to treat the Mexico Mine tailings due to poor recovery of gold and silver by cyanide leaching. The majority of the concentrate is composed of silica, iron and calcium gangue material. The auger drilling conducted in 2018 provided the large quantity of samples to be tested. Due to the grade differences in gold and silver between the upper, middle and lower sections of the tailings (defined by approximately 6 meters), a composite was made of each as shown:\n\n \n \nAverage Grades\n\n\n \n Au (g/t) Ag (g/t)\n\n\n \n Upper 2.623 54.64\n\n\n \n Middle 3.422 101.49\n\n\n \n Lower 2.935 99.65\n\n\n \n Overall 2.993 85.26\n\n \n \nFlotation test work on the composites was done on either 600 or 1,000 gram samples. The samples were screened at 325 mesh and the oversize was ground in a lab rod mill so that the overall float sample was approximately 95% -325 mesh. Flotation tests were conducted using a Denver D12 lab float cell at approximately 25% solids. Recoveries from the flotation testing of each section showed the following:\n\n \n \nRecovery (%)\n\n\n \n Au Ag\n\n\n \n Upper 79.87 58.77\n\n\n \n Middle 80.84 68.71\n\n\n \n Lower 79.62 75.13\n\n\n \n Average 80.11 67.54\n\n \n \nA bulk composite of the upper, middle, and lower portions was made and tested by flotation as follows:\n\n \n \nRecovery (%)\n\n\n \n Au Ag\n\n\n \n Test #33 75.17 61.58\n\n\n \n Test #34 75.94 65.66\n\n\n \n Average 75.56 63.62\n\n \n \nThe test work as shown above is all single stage flotation which assumes all other secondary recovery processes like scavenge and cleaner tails values will report to the concentrate. This is not true all the time so in order to provide a more accurate...
