Ongoing plant improvements included an upgrade to the concentrate thickener underflow pipeline to the filter press surge tank. One of the concentrate thickener overflow pumps was replaced with a bigger pump along with a new pipeline; a standby pump will be installed once refurbishment work is completed. Modifications to the cleaner flotation circuit were initiated to allow cleaning of the first rougher concentrate to produce a cleaner final concentrate during processing of transition ore types.

Flotation recovery continued to be variable due to the inconsistent quality of the transition ores processed. New flocculant was received for the water recovery thickener, allowing the flotation circuit to operate at the design pH 9.0-9.5. Dosing of the sulphidising agent sodium sulphide continued along with copper sulphate as activator. Some daily recoveries of over 80% and sometimes 90% were recorded, with reconciled recovery of 73.6% reported for December 2023.

Construction of the concentrate shed has been completed and the lighting power supply connected. Roofing was installed over the rougher and cleaner flotation cells. The one tonne bulk bagging system was delivered to Port Klang and transported to the Selinsing site. The contract for the new flotation tailings hopper was awarded and fabrication initiated; civil works commenced in mid-December 2023 and installation of the tailings hopper and associated pipework is scheduled in the 1^st week of February 2024.

The procurement plan and strategies have been tabled for review focusing on critical spare parts for the sulphide flotation plant and by allocating resources to enhance this improvement with the aim to avoid any unforeseen stoppage of plant operations.

Mining and Ore Stockpile Buildup

Mining of Buffalo Reef pits continued with Stages 1 and 2 mined at BRC2 and BRC3 pits and Stage 1 started at BRC4. Delivery of fresh and transition ore continued and the run of mine (ROM) stockpile was increased to 255,000 tonnes, which is over three months’ processing plant capacity, at the end of December 2023 and critically ahead of the imminent Northeast monsoon season.
