With the completion of the flotation plant construction at the Selinsing Gold Mine in Malaysia, the sulphide treatment plant has been placed into commissioning after the oxide plant production ceased in mid-November 2022. The first gold concentrate was filtered on December 27, 2022 and the ramp up period commenced in January 2023. President and CEO Cathy Zhai commented, “During commissioning we have identified some bottlenecks and are working with Mincore to fix them. Up to date the flotation plant has delivered saleable concentrate of approximately 1,707 dry tonnes at 35.12 g/t Au with gold content of 1,928 troy ounces. In the meantime, with unexpected heavy rainfall in the dry season, we also are focused on acceleration of the mining rates to fulfill commercial production requirement.” Figure 1.

Plant Inspection Flotation Commissioning Progress The commissioning stages include: (1) preparation - to confirm the completeness of construction and deliver the commissioning plan for test work, (2) dry commissioning - to test if mechanical, electrical and electronic equipment and components in the circuit are installed correctly and completely according to designed protocols and their availability, (3) wet commissioning - to test circulation of water through the flotation circuit and the plant as a whole ensure the water and pumping system up running for the designed purpose;(4) ore commissioning - to start-up with first fill to verify flotation performance and tune it to meet the designed performance in connection with front end circuit, this includes but not limited to the control level, the flows in relation to each components in the circuit and to overall treatment process, the water balance and mass balance. During the commissioning process the bottlenecks will be identified and corrected. After the start-up ore commissioning, a ramp up period will tune the plant under increased mill feed and required conditions until commercial production is reached. The management and board would consider the commercial production is reached when the flotation plant is running for 30 days co...
