:: Banks Island Gold Update on Commissioning of Grinding and Flotation Circuit
Production of Flotation Concentrate has commenced at Yellow Giant. Gold Recovery currently estimated at +90%. Current mill throughput at 100tpd with plans to increase to 200tpd over coming weeks.
Banks Island Gold Ltd. is pleased to report that the commissioning of grinding and flotation circuits is in progress and production of gold concentrate has recommenced at the Yellow Giant Gold Property, located on Banks Island, British Columbia.
Company crews completed construction of the grinding and flotation circuits at Yellow Giant on August 6th and commenced processing mineralized material on August 7th. During the period from August 7th through August 25th, the Company has focused on crew training, improving plant availability, and optimizing concentrate grade and gold recovery.
The implementation of grinding and flotation circuits has resulted in a dramatic improvement in metallurgical gold recoveries from previous Dense Media Separation Plant production. The average gold grade of final tailings to date is less than 1gpt Au resulting in a concentrate grade averaging 64gpt Au. The Company estimates that metallurgical gold recovery exceeds 90%.
Plant availability and throughput have been improving since the commissioning commenced and now averages ~100 tonnes per day. The Company continues to work on improvements to throughput including the installation of a larger mill cyclone and additional tailings filter press capacity, both of which are expected to be in place during the first week of September. Installation of these components will require minimal interruption to production. After these components are fully operational, the Company expects plant throughput to increase to 200 tpd.
