[{"type":"text","content":"Gold Terra Announces Initial Gold Recovery of 92% on Yellorex Zone, Con Mine Option Property, Yellowknife, NWTVANCOUVER, BC / ACCESSWIRE / August 31, 2022 / Gold Terra Resource Corp. (TSXV:YGT)(Frankfurt:TX0)(OTCQX:YGTFF) (\"Gold Terra\" or the \"Company\") is pleased to announce excellent gold recovery from its initial metallurgical tests on the Yellorex zone part of the Campbell shear. The Yellorex zone is located approximately two (2) kilometers south of the former producer, the Con Mine, which is under option from Newmont Corporation (the \"Con Mine Option Property\"). The Yellorex zone is adjacent to the Company's 100% owned Yellowknife City Gold project (the YCG Project\"), Northwest Territories.HighlightsTotal gold recovery of 92.1% achieved in our first testwork in the high-grade composite samples of 10 g/t Au, after flotation concentrate, pressure oxidation (POX), and cyanide leach.Excellent gold assays reporting up to 98.8% of gold in the flotation concentrate with close to 7% sulphide content.Results provide Gold Terra with two potential product paths for Yellorex mineralization either to:produce a saleable concentrate, orproduce gold on site through the POX processThe Con mine (1938-2003) produced over 6M oz of gold over more than 50 years mine life. Historically gold mineralization encountered at shallower depths in the mine (generally above 1000m) was likely refractory gold, while deeper mining was free-milling gold, hence a gravity circuit was added by Nerco in 1989. In the more recent years (1987-2003), the former Con Mine operated with a flow sheet including a gravity circuit, a flotation circuit, follow by a Pressure Oxydation (POX) Circuit, or autoclave. Nerco, with selective free milling ores, achieved up to 95% recovery, while Miramar Mining increased the throughput from 800 ton per day (tpd) to 1400 tpd and achieved 88 to 90% recovery by mixing free milling ore with refractory ore after the acquisition from Nerco in 1993.The Yellorex zone is currently drilled at shallow depths (surface to approximately 300 metres), and therefore was expected to be refractory. Metallurgical testwork was performed by SGS Lakefield (SGS) on core reject samples obtained from drill hole GTCM22-030 (6.41/t gold over 26.50 metres including 9.05 g/t over 4.00 metres; 10.66 g/t gold over 3.0 metres; and 14.15 g/t gold over 5.50 metr...
