DEVELOPMENT

Selinsing Gold Mine

Plant Improvements

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.

The optimization of the flotation reagent suite has been ongoing, with a focused approach towards refining the use of key components. Additionally, issues previously encountered with the flotation air blowers have been successfully resolved, following comprehensive troubleshooting conducted by Atlas Copco technicians. As results, the reconciled recovery of 71.10% was reported for December 2023. Some daily recoveries were over 80% and sometimes 90% were recorded.

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 pending finalization. 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 1st 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.

Tailing Storage Facility (TSF) Upgrade

The expansion of the TSF, which was initiated in February 2021, aimed to raise the TSF’s level to 540m RL, which will allow an additional three-year capacity for the sulphide concentrate production. As of the end of FY 2022, the TSF upgrade project had reached a commendable completion rate of 92.30%, with the main embankment level at 537.00m RL. An additional phase of construction resumed in the first quarter of FY2024 and achieved levels of 539.25m RL. The additional 0.75m RL required to reach the required level of 540m RL was achieved in Q2 2024.

A monitoring system, which comprises 11 prisms installed at the TSF main embankment, has been instrumental in ensuring structural integrity. Bi-weekly readings indicated a total vertical movement of only 6.30mm for the quarter, with no significant deviations observed. As of the end of Q2 FY2024, the total progress of the fill work stands at 100%.

Murchison Gold Project

During Q2 2024, the Company continued working on the review of the Murchison Gold Project, including reassessment of the economics of potential cash flow generation. Also, the Company performed a review of all historical and recent drillhole data for the Gabanintha tenement holdings, in order to plan infill drilling programs for completion in subsequent quarters with a view to potentially report NI-43 101 compliant resources in the area.

Processing plant, accommodation, catering facilities, offices, and associated infrastructure were maintained to a high standard ensuring operational readiness for commissioning in the eventuality that production restarts. Accommodation and catering facilities were fully operational during the quarter and equipped to support administrative, exploration, and mining activities.

Exploration

Malaysia

There was no exploration drilling undertaken at Selinsing during the quarter. Exploration activities to identify additional oxide and sulphide mineralization are expected to resume during later stages of FY2024.

Western Australia

Burnakura: During Q2 FY2024, the Company continued to review and update internal studies for production opportunities at Burnakura, following the completion of the Selinsing Sulphide Gold Project during fiscal 2023. During the quarter, construction of a new drill core storage yard located at Burnakura continued with optimized racking, cutting, and core logging facilities which will be completed during Q3 2024.

Gabanintha: Review of Gabanintha Gold Project historical resources continued as part of updating internal studies. Historical data received from regulators in Q2 FY2024 was reviewed in the quarter. Estimation of infill drilling requirements for the existing main pits was completed for corporate review.

Tuckanarra: In August 2023, the Company received notification from Odyssey Gold Ltd (“Odyssey”) that a major milestone of resources was achieved at the Tuckanarra Joint Venture project, which triggered a due Performance Payment of AUD$1.00 million. Both Monument and Odyssey agreed to defer the payment by six months after the date of satisfaction of the milestone, specifically by February 2, 2024. Subsequent to December 31, 2023, Monument and Odyssey agreed upon an additional two-week extension. The payment of AUD$1.00 million plus interest has been received on February 23, 2024.
