Monument Mining Ltd. Reports Third Quarter Fiscal 2023 Results

President and CEO Cathy Zhai commented, "I am pleased to report that during the third quarter our Selinsing Gold Mine in Malaysia commenced sulphide production. With off-take agreements now secured, and the first batch of gold concentrate ready for sale after the end of the quarter, cashflows are expected to be higher in future quarters, underpinned by ongoing improvements in sulphide plant performance towards full production. The Company will use the cash generated from the sulphide concentrate sales for the development of the Murchison Gold Project in Western Australia and other corporate development initiatives."

Third Quarter Highlights:

• Selinsing sulphide flotation plant has begun its ramp up production phase, during which deficiencies were identified and addressed through an action plan.
• New mining fleet arrived to enhance mining rates.
• Off-take agreements were secured with competitive commercial terms.
• Export permits granted to multiple buyers late in May after the quarter end; the first batch of gold concentrate production of 2,000 Dry Metric Tonnes ("DMT") is in progress for sale.
• Gold bullion production:

Q3 FY2023 Production Analysis

Gold Bullion Production

• 104 ounces of gold was recovered from a clean-up of the Carbon in Leach ("CIL") circuit, which is now on care and maintenance, which can be converted back to treat oxide ore in the future.
  

Gold Concentrate Production

• Following the commissioning of the sulphide flotation plant in December 2022, Q3 FY2023 gold concentrate production was 2,107 dry metric tonnes ("DMT") containing 2,412 ounces of gold, from the processing of 89,151 tonnes of sulphide ore (Q3 FY 2022: nil).
• A total of 98,725 tonnes of sulphide ore was processed in the nine months ending March 31, 2023, producing 2,137 tonnes of concentrate containing 2,440 ounces of gold.
• Total ore mined during the quarter was 82,100 tonnes compared to 103,380 tonnes in Q3 FY2022, with the decrease due to unexpected heavy rain in February and a shortage of explosives. Total waste removal increased to 2,235,216 tonnes (Q3 FY2022: 1,194,143 tonnes) due to increased waste removal in the free digging areas at the BRC2 and BRC3 pits during the quarter when explosives were not available.
• Mill feed of 89,151 tonnes was fully for flotation production at a feed grade of 1.99g/t with recovery of 42% and a mass pull of 2.35%. The low gold recovery was caused by the processing of highly oxidized first fill materials during the ore commissioning period in Q2 FY2023, with the high-grade tailings discharged to a dedicated tailing pond for future retreatment.
• Ore processed during the quarter was lower than planned due to loss of production from a gear box failure in March, which has since been fixed.
• Furthermore, production is expected to improve into Q4 FY2023, following the mining of higher-grade gold zones at the end of the current quarter.

Q3 FY2023 Financial Analysis

• Q3 FY2023 gold bullion sales generated revenue of $2.63 million as compared to $6.16 million in Q3 FY2022. Gold sales revenue was derived from the sale of 1,400oz (Q3 FY2022: 3,270oz) of gold bullion at an average realized gold price of $1,878 per ounce. (Q3 FY2022: $1,911 per ounce). There was no sale of gold concentrate during the quarter.
• Gross margin of $0.42 million resulted from sales of remaining gold bullion inventory before operational expenses and non-cash amortization and accretion (Q3 FY2022: $0.16 million). The increase in gross margin was due to lower costs associated with the CIL plant which was held on care and maintenance.
• Net loss was $0.84 million, or ($0.00) per share compared to a net loss of $2.84 million or ($0.01) per share for Q3 FY2022.
• Cash cost per ounce of gold bullion sold decreased by 14% to $1,580/oz as compared to $1,835/oz in the same period last year. The decrease was due to lower cost on addition gold cleaned up from gold-in-circuit in Q3 when the CIL circuit was put on care and maintenance.
• The cash and cash equivalents balance as at March 31, 2023 was $10.11 million, a decrease of $10.93 million from the balance at June 30, 2022 of $21.04 million, comprised of $13.50 million sulphide project development costs at Selinsing including the flotation plant construction, tailing storage facility upgrades and cutback, river diversion and stripping activities, $0.82 million for Murchison exploration and maintenance activities, and $0.06 million for long-term lease obligations, offset by $3.45 million generated in operating activities. As at March 31, 2023, the Company had positive working capital of $14.55 million as compared to $30.33 million at June 30, 2022.
  

Development

Selinsing Gold Mine

The sulphide project development at the Selinsing Gold Mine in Malaysia has been the recent focus of the Company. As of March 31, 2023, the Project has been completed with total costs of $18 million which includes $11 million for the flotation plant construction and $7 million for mine development, comprising mainly waste removal, river division and improvement of the tailing storage facilities.

During Q3 FY2023 the flotation plant construction was completed, and most ancillary equipment installed, except for the bagging system and permanent concentrate warehouse, which are due to be completed in Q4 FY2023. The ramp up to full production commenced in January 2023, and is expected to be completed in June 2023.

Murchison Gold Project

At Murchison the Company continued to review historical data at the Gabanintha project, and drilling was deferred to preserve cash during completion of the Selinsing sulphide project development.

The Company continued to ensure that the Burnakura plant and other facilities are operationally ready through its care and maintenance program to ensure efficient commissioning in the future. Site accommodation and catering are fully functional in readiness for the Company's personnel and mining contractors when a restart is approved.
