Manuka Resources has praised a cutting-edge gold solution circuit from the successful industry collaboration between Gekko Systems and Cadia Systems which supplied a solution for its Mount Boppy project at Canbelego, NSW. Carbon elution and regeneration systems are crucial to the overall efficiency of any CIL/CIP plant.
The Gekko- Cadia packaged solution provides customers with the optimal design for both Pressure Zadra (PZ) and Anglo American (AARL) elution options. Gekko-Cadia say they offer clients a complete solution either as a turnkey modular package or as major components for larger scale circuits.
“I could not fault attention to detail and effort put by Tim Bell and the entire Gekko team to make the Manuka Resources gold elution plant a success,” said Manuka Resources Operations Manager David Power. The Gekko-Cadia elution circuit commenced operations in September 2020, and the on-site furnace is now operating. Manuka now produces gold dore bars on site.
The Mount Boppy gold mine is located approximately 50 km east of Cobar. Underground mining from 1897 to 1923 extracted gold oreto a maximum depth of 230mbelow surface. Open pit mining by Polymetals and Black Oak Minerals occurred in two phases between 2002-2005 and in 2015 down to a maximum depth of 80 m below surface level. Open pit mining by Manuka recommenced in mid-2020.
Mt Boppy gold mine and neighbouring tenements host an existing open pit Measured and Indicated Resource of 351,430 tonnes grading 4.62g/t gold, basedon a cut-off grade of 1.6g/t for material within its current open pit design and a cut-off grade of 3.0g/t for material below the current pit design, and an inferred resource of 11,000 t grading 6.7 g/t below the designed pit reported at a 3.0 g/t cut off. The Mt Boppy project is processing its gold ore through the company’s processing plant at Wonawinta.
For the December 2020 quarter, a total of 81,840 t of ore was mined, while 87,321 t were trucked to the Wonawinta plant at an average grade of 2.34 g/t gold. Produced ounces for the quarter stood at 3,628.
The Mt Boppy Resource Update announced February 1, 2021 materially increased the deposit grades and tonnages, along witha substantial tonnage increase moved from indicated tothe measured category, resulting in an overall uplift in the remaining gold ounces for the project.
