Monument Mining Limited updated the progress at the Selinsing Sulphide Project. The ramp-up of the flotation plant has made great headway, with the mill feed rate of 113 dry tonnes per hour achieved, being 95% of the design capacity of 119 dry tonnes per hour. The plant construction and mine development consumed a total of $18 million, in line with the budget.

The ramp-up of the flotation plant continued, with the mill feed rate of 113 dry tonnes per hour achieved, being 95% of the design capacity of 119 dry tonnes per hour. During this ramp-up process bottlenecks have been identified and the team has been working to correct them in order to ramp up to commercial production. The ramp-up period is expected to be completed in June 2023.

Certain design deficiencies have been detected and revision of designs have been received to improve performance efficiencies including design of a new rougher flotation tailings hopper and associated pipework, structural and civils drawings and specifications for the new concentrate thickener overflow pumps. Pump suction and delivery lines will be upgraded as well as the power supply to the bigger motors required. None of the above works has material impact on current flotation plant operations.

The flotation plant experienced major shutdowns from early March to first week of May. The Metso- Outotec concentrate thickener rake drive gearbox was broken, replaced by a new gear box assembled in Australia, airfreighted to Malaysia, and installed. The concentrate thickener was then recommissioned, and all concentrates were recovered to the circuit.

Further loss of production occurred in April until May as the filter press cloths started failing prematurely due to manufacturing defects; the supplier has accepted the defects and will supply two new sets of higher permeability filter cloths. In the meantime, replacement filter press cloths were sourced and delivered from local suppliers. Management is focused on reviewing all critical parts and in advancing the procurement plan.
