[{"type":"text","content":"Kenorland Minerals Announces Additional Metallurgical Test Results at the Frotet ProjectVancouver, British Columbia--(Newsfile Corp. - August 21, 2023) - Kenorland Minerals Ltd. (TSXV: KLD) (OTCQX: KLDCF) (FSE: 3WQ0) (\"Kenorland\" or the \"Company\") is pleased to announce the results of additional metallurgical testing of the Regnault gold system (\"Regnault\") on the Frotet Project (the \"Project\"), located in northern Quebec and held under joint venture (the \"Joint Venture\") with Sumitomo Metal Mining Canada Ltd. (\"SMMCL\"). Metallurgical study highlights include: Optimized recoveries of up to 93.3% Au and 90.5% Ag for whole ore leachingResults of the Additional Metallurgical StudyA preliminary metallurgical study at Regnault was initiated in July 2022 with the completion of drill hole 22RDD149 (29.20m at 16.61 g/t Au including 9.85m at 44.89 g/t Au*). The objective was to characterise the amenability of cyanide extraction of Au and Ag. Results of the study, summarised in a press release dated January 18, 2023, indicated promising Au-Ag recoveries, and identified additional steps to further maximize recovery. The follow up study investigated the effects of gravity separation prior to cyanide leaching, flotation prior to cyanide leaching, finer grinding, and the use of an activator to increase reaction kinetics during cyanide leaching. (*See press release dated November 14, 2022).When comparing the different flowsheet options investigated for the Regnault style ore, the highest recoveries were realized with optimized whole ore leaching, with 93.3% Au and 90.5% Ag recovered. Combined gravity separation and cyanide leaching were 90.0% for Au and 90.6% Ag. Flotation testing when combined with gravity separation and cyanide leaching were lower than whole ore leaching, at 83.7% Au and 82.1% Ag. Compared to the whole ore leaching process the amount of cyanide contact material that would be reduced by flotation is 5.8% and cyanide consumption is reduced by 65.0%. These results indicate that the Regnault style ore is amenable to conventional cyanide leaching with recoveries of up to 93.3% Au and 90.5% Ag.Details of the Metallurgical StudyMaterial from the original program (27.1m of NQ half drill core from 22RDD149) was used for the additional testing. Samples were crushed to under 1.7mm and thoroughly mixed. 1kg samples were spli...
