Third Quarter and YTD Production and Financial Highlights

GOLD PRODUCTION RESULTS

Third quarter gold production

• A total of 2,977,745 tonnes of material were mined during Q3 FY2024, a 28% increase from 2,317,316 tonnes during Q3 FY2023. This included 200,676 tonnes of ore mined, up by 144% from 82,100 ore tonnes mined during Q3 FY2023, and 2,777,069 tonnes of waste mined, up by 24% from 2,235,216 during Q3 FY2023. The stripping ratio improved to 13.84 compared to 27.23 during Q3 FY2023.

• The gold concentrate production in Q3 FY2024 yielded 5,488 ounces of gold. The mill processed 166,478 tonnes of sulphide ore, achieving a head grade of 1.49g/t and a recovery rate of 68.50%. This performance marks a notable improvement from Q3 FY2023, where 2,412 tonnes of sulphide ore at a head grade of 1.99g/t and a recovery rate of 41.75% were achieved. A key factor in this enhanced recovery has been the shift from processing old stockpile ore to feeding high-grade transition ore and fresh sulphide ore, along with numerous improvements implemented at the processing plant. Mill availability of the flotation plant was at 84.90% during Q3 2024 which is lower than planned and was primarily due to the tie-in of the new rougher tailings hopper and associated pipework, a TSF powerline failure and high levels of concentrate in the surge tank at the filter press. To address this, pH adjustment is now carried out at the filter press surge tank to improve filter cake quality and easier removal from the filter cloth. Further upgrades to the filter press have been planned, and are expected to be completed in October of 2024, with a budget of roughly $1 million.

YTD 2024 gold production

• Mine production included total material mined of 8,355,584 tonnes (nine months ended March 31, 2023: 6,242,220 tonnes), comprising 790,264 tonnes of ore (nine months ended March 31, 2023: 298,351 tonnes) and 7,565,320 tonnes of waste (nine months ended March 31, 2023: 5,943,868 tonnes). The stripping ratio improved to 9.57 compared to 19.92 during YTD FY2023.

• The mill processed 536,189 tonnes of sulphide ore during the nine months ended March 31, 2024, averaging a head grade of 1.62 g/t and a recovery of 69.82%. This compares with 98,725 tonnes of sulphide ore at a head grade of 1.98g/t and a recovery rate of 40.86% processed during the nine months ended March 31, 2023.

DEVELOPMENT

Selinsing Gold Mine

Plant Improvements

As part of the ongoing plant optimization, a new rougher tailings hopper was installed, along with the rougher tailings pumps upgraded with new motors and power supply. A bigger rougher concentrate launder was also installed to replace the original undersized unit and solve excessive spillage issues. Further upgrades to the filter press have been planned and are expected to be completed in October of 2024.

Tailing Storage Facility (TSF) Upgrade

Expansion of the Tailings Storage Facilities (“TSF”) was initiated in 2021 in order to raise the TSF’s level to 540m RL at the main embankment. This was to accommodate an additional three-year TSF capacity in relation to the sulphide concentrate production. The final stage of the 0.75m RL TSF expansion was achieved in Q2 2024. A new spillway at the saddle dam at 539.2m RL was also completed by the end of Q3 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 Q3 2024, the total progress of the fill work stands at 100%.

Murchison Gold Project

During Q3 2024, the Company continued working on a review of the Murchison Gold Project, including reassessment of the economics of potential cash flow generation. The Company also continued to review all historical and recent drill hole data for the Gabanintha tenement holdings, in order to plan infill drilling programs for completion in subsequent quarters with a view to updating the SRK NI 43-101 Report “Mineral Resource estimation at Burnakura” dated July 2018.

Construction of a new core shed was completed in March 2024, including new core yard racking and trays. Drill cores samples have been reorganized to be ready for geological inspection. A heritage specialist was engaged after Q3 2024 to research and update the regulatory changes in this regard and other regulatory compliance was also under review. Processing plant, accommodation, catering facilities, offices, and associated infrastructure were maintained to a high standard ensuring operational readiness for commissioning in the event that production restarts.

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 later in FY2024.

Western Australia

Burnakura

During Q3 2024, the Company continued to review and update internal studies for production opportunities at Burnakura, following the completion of the Selinsing Sulfide Gold Project during fiscal 2023. During the quarter, construction was completed on a new drill core storage yard located at Burnakura with optimized racking, cutting, and core logging facilities. Cores have been reorganized ready for geological inspection. A heritage specialist was engaged after Q3 2024 to research and update the regulatory changes in this regard and other regulatory compliance was also under review.

Gabanintha

A review of the historic resources at Gabanintha continued during the quarter, including reviews of historical data received from regulators in Q2 2024, with conformation and infill drilling programs for the historical main pits to follow.

Tuckanarra

On August 3, 2023, the Company was notified by Odyssey Gold Ltd. that a major milestone of resources had been achieved at the Tuckanarra Joint Venture Project. This triggered an AUD$1.00 million Performance Payment; the payment plus interest was received by Monument on February 23, 2024.
