[{"type":"text","content":"\n \n \n \n 13 June 2022\n \n \n \n \n Oracle Power PLC\n \n \n \n \n (\"Oracle\" or the \"Company\")\n \n \n \n \n \n \n \n \n \n Improved Gold Recovery of up to 94.7% Received from Further Positive Metallurgical Results\n \n \n Northern Zone Gold Project\n \n \n \n \n \n \n \n \n Oracle Power PLC (AIM:ORCP),\n the international natural resources project developer,\n is pleased to announce that further positive metallurgical results have been returned from the three samples from its 100% owned Northern Zone Gold Project, located 25km east of Kalgoorlie in Western Australia (\"Northern Zone\" or the \"Project\"). The samples were submitted to Nagrom in Perth for cyanidation bottle roll tests. The results indicate that an average gold recovery of 88% over 12 hours and 92.9% on average over 24 hours can be achieved from the three samples. The positive metallurgical results to date form the basis for a drill programme to define a maiden inferred JORC resource.\n \n \n \n \n \n Highlights:\n \n \n ·\n Metallurgy results from the three samples include:\n \n \n o \n Drill head grade (average) of 0.79g/t Au\n \n \n o \n 92.9% (average) of gold extraction after 24hr bottle roll from three samples\n \n \n o \n Very low copper content of 2ppm into solution\n \n \n ·\n An Exploration Target of 200-250Mt at 0.4\n -\n 0.6g/t Au for 2.5-4.8Moz gold, has been generated based on results to date.\n \n \n ·\n Northern Zone is an\n Intrusion Related Gold System (IRGS)\n with wide gold mineralised felsic porphyry intrusions. This type of system\n can host significant ounces of gold, such as Boddington Goldmine (WA), Fort Knox (Alaska), Dublin Gulch (Yukon) and Timbarra (NSW).\n \n \n ·\n Diamond and reverse circulation drilling programme to define a maiden inferred JORC resource has been designed and is expected to be finalised in the coming weeks.\n \n \n \n \n \n \n \n \n The first set of results previously announced (9 June 2022) indicated that good gold recoveries can be achieved within 6 hours of 83.3%, and up to 90.4% gold recovery over 72 hours. The results announced today (Table 1) utilise a set of conditions/parameters (Kinetics) based on the previous result, but changed to improve recoveries, with a maximum individual recovery from sample 2 of 94.7% after 24 hours, with an average r...
