[{"type":"text","content":"Aton Reports New Metallurgical Testwork Results from Rodruin Oxides with Gold Recoveries up to 93.4%VANCOUVER, BC / ACCESSWIRE / March 9, 2023 / Aton Resources Inc. (TSXV:AAN) (\"Aton\" or the \"Company\") is pleased to update investors on the results of further metallurgical testwork from its Rodruin advanced exploration project. Rodruin is located within the Company's 100% owned Abu Marawat Concession (\"Abu Marawat\" or the \"Concession\"), in the Eastern Desert of Egypt.Highlights:5 composite samples representing the range of oxide mineralisation types at Rodruin underwent further metallurgical testwork investigating both heap leach and conventional CIL technologies. The composite samples were prepared from selected diamond drill half core intervals;4 samples were selected for whole ore cyanidation leach tests at P 80 grind sizes of -75µm and -106µm. Test results showed slightly higher gold and silver extractions at the finer grind size. Gold recoveries ranged between 87.7% and 93.4%, after 48 hours of leaching. Silver recoveries ranged from 50.9% to 65.7%. At the P 80 grind size of -75µm gold and silver recoveries averaged 90.4% and 59.0% respectively;All 5 samples were subjected to coarse ore bottle roll leach testing at a crush size P 100 of -8mm. The test results showed average gold recoveries ranging between 66.2% and 75.3%, after 30 days of leaching. Average silver recoveries ranged from 19.3% to 30.8%;Whole ore and coarse ore bottle roll cyanidation leach tests indicate that all the Rodruin mineralisation types tested are amenable to processing via both conventional CIL and heap leach technologies.\"These metallurgical testwork results from the Rodruin oxides are again very encouraging, following on from the initial scoping level testwork which we undertook in 2021,\" said Tonno Vahk, Interim CEO. \"The gold recoveries are good and indicate that the oxides from all the main mineralised zones at Rodruin will be amenable to processing by both conventional CIL and heap leach technologies. The Company is working towards its planned application for the mining licence at the Abu Marawat Concession in Q3 this year, based on the definition of \"commercial discoveries\" at both Rodruin and Hamama West, in accordance with our Concession Agreement with the Egyptian Mineral Resources Authority. The application will...
