Classic Minerals commences wet commissioning at Kat Gap processing plant, WA

Junior explorer Classic Minerals (ASX:CLZ) has begun the wet commissioning of the processing plant at its Kat Gap Gold Project in Western Australia. 

The company will use part of the bulk sample ore to complete this wet commissioning phase and the ongoing calibration required for efficient and automated throughput before processing the balance through the gravity circuit. 

the stage one processing facility has a throughput of up to 100,000 tonnes per annum

Classic says the stage one processing facility has a throughput of up to 100,000 tonnes per annum. 

However, during wet commissioning, Classic will take the opportunity to log recovery data, which will be used to further progress its design work for the stage two expansion of the process plant. 

The company will look to introduce a carbon-in-leach (CIL) circuit and upscale the milling to achieve a throughput of up to 200,000 tonnes per annum in stage two. 

Classic is continuing its civil works study for stage two expansion of the Kat Gap Gold Project, which includes processing run-of-mine (ROM), increased water supply and storage facilities, and the development of additional access roads, workshops, administration buildings, and tailings storage. 

Further, the company has completed the drilling of a second water bore, which is producing ‘significantly’ more water than the first bore. 

The 2 bores are now active and will be engaged to supply the required amounts of water for the processing plant and other operational and development needs of Classic Minerals. 

Classic Minerals is a Western Australia-based mineral explorer that holds a pipeline of projects across 575km-square of tenements. 

As of 31 March 2023, the company had $198,000 cash and cash equivalents at hand and $19.55 million in unused finance facilities, according to its latest quarterly report.
