Please try againMetallurgical studies were conducted on a composite sample of massive to disseminated sulphide mineralisation from drill holes completed in 2023 / 2024.The objective was to determine the amenability of the mineralisation to respond to conventional sequential flotation methods and produce marketable copper and nickel concentrates.Head assays were 0.82% copper, 1.64% nickel (1.38% nickel in sulphide), and 0.11% cobalt.Based on the batch tests, copper recoveries of 75-80% and nickel of 60-65% can be expected. Further testwork, including locked-cycle studies (LCT), is anticipated to improve recoveries.Nickel concentrate grades of 14-16% were produced and included in excess of 1% cobalt. Such a concentrate would be considered ‘highly attractive to nickel smelters’ (Blue Coast).The nickel concentrate contained 0.54% copper which would be payable.Copper concentrate grades of ~25% with <1% nickel content are considered typical of this style of mineralisation. The low nickel content falls below the penalty charge levels.Richard Williams, CEO of Winshear, commented;“These are very positive results at this stage of the Portsoy Project. It was key for us to understand the metallurgical characteristics of the mineralisation and to ensure the recoverability of the copper, nickel and cobalt and the quality of the concentrates produced at an early stage.“The results provide confidence that the Rodburn mineralisation can be processed using conventional methods, with the potential to produce saleable copper and nickel concentrates, supporting the case for further optimisation testwork as the project advances.”A report entitled ‘Rodburn Project – Cu-Ni Flotation’ authored by Rob Thorpe of Blue Coast can be viewed here.J.
