Fourth Quarter and Fiscal Year 2023 Production and Financial Highlights

GOLD PRODUCTION RESULTS

Annual gold production

• The CIL plant production in FY2023 recovered 2,910oz of gold with the mil feed of 195,264 tonnes, the average grade of 1.03g/t at the recovery of 44.87%, down from 7,564oz in FY2022 with the mill feed of 544,003 tonnes, the average grade of 0.69g/t at the recovery of 62.66%. Gold produced during the year amounted to 3,926oz, compared to 7,091oz in 2022. The decrease in recovered and produced gold were primarily resulted from the cessation oxide production in November 2022, the CIL circuit was put under care and maintenance and the sulphide flotation plant commenced commissioning and into production in the fourth quarter.
• The sulphide flotation production in FY2023 produced 6,849 ounces of gold. The mill processed 223,493 tonnes of sulphide ore at a head grade of 1.80g/t with a recovery of 54.06%. The lower gold recovery was due to the treatment of highly oxidized first-fill materials during the ore commissioning period. Consequently, the high-grade tailings were stored in a high-grade tailing pond for future process.
• Mining focused on Selinsing Pit and Buffalo Reef Pits to remove overburden for sulphide production. A total of 439,022 tonnes of ore was produced (FY2022: 355,519 tonnes) with 8,051,617 tonnes of waste (FY2022: 5,593,875 tonnes) was moved at a higher stripping ratio of 18.34 compared to 15.73 is the prior year primarily due to the mining sequence.
  

Fourth quarter gold production

• The CIL plant closing operation cleaned up 362 ounces of gold from the circuit with no mill feed as compared to the same period of FY2022 where 1,942oz of gold produced, 1,998oz recovered from the mill feed of 119,409 tonnes at the average gold grade of 0.95g/t and a recovery of 54.72%.
• The sulphide flotation plant produced 4,409 ounces of gold. The mill processed 124,768 tonnes of sulphide ore at a head grade of 1.66g/t with a recovery of 66.47% improved from Q3 production.

FINANCIAL RESULTS

Fiscal 2023 financial results

• Gold sales resulted in a revenue of $12.39 million, a decrease from the $14.44 million in Fiscal 2022. Gold revenue comprised of $10.64 million from 5,912oz of gold produced out of oxide ore at an average realized price of $1,800 per ounce (FY2022: 8,016oz at $1,870 per ounce), and $1.75 million from 1,148oz of gold produced from sulphide ore at the realized gold price of $1,949/oz (FY2022: nil).
• Gross margin was at $1.75 million (FY2022: $0.63 million) from Selinsing production primarily due to high fixed cost incurred for the CIL operation period while the CIL was transited to care and maintenance.
• The cash cost per ounce from the oxide plant decreased by 6% to $1,622/oz for the year down from $1,723/oz in FY2022. This was attributed to a higher mill feed grade, partially offset by a decrease in recoveries to 44.87% (CIL) from 62.66% (CIL) in FY2022. The cash cost per ounce from the sulphide flotation plant was $917/oz (FY2022: NA).
• As of June 30, 2023, cash and cash equivalents were $5.96 million, a decrease of $15.08 million from June 30, 2022. The Company’s cash and cash equivalents primarily comprised funds held with reputable financial institutions and were invested in cash accounts. The decrease was primarily due to the prolonged ramp-up period and a breakdown in the sulphide flotation plant. Commercial production only began in August 2023 subsequent to the year end.
• Cash used in investing activities of $15.12 million (FY2022: $12.99 million) represented $14.17 million invested in Selinsing for sulphide project development, including the Flotation Plant construction, Tailings Storage Facility ("TSF”) upgrades and cutbacks, river diversion, and stripping activities (FY2022: $10.73 million), while $0.95 million (FY2022: $2.26 million) was invested in Murchison exploration and evaluation projects.
  

Quarter four financial results

• Q4 gold sales generated revenue of $3.18 million from 1,910oz gold sold, comprised of $1.44 million from the oxide processing plant for 762oz of gold at an average realized price of $1,883 per ounce (Q4 FY2022: 450oz at $1,890 per ounce), and $1.74 million from the sulphide flotation plant for 1,148oz of gold at the average realized gold price of $1,949/oz (Q4 FY2022: nil).
• Mining operations before non-cash amortization and depreciation generated a gross margin of $0.45 million, an increase of 64% from $0.27 million in Q4 FY2022.
• The cash cost from the oxide CIL gold production increased by 72% to $2,200/oz for the fourth quarter from $1,282/oz in the fourth quarter of FY2022. This was mainly resulted from high fixed cost incurred to recover the residual gold from the CIL circuit. The cash cost from the sulphide flotation gold production was $917/oz (Q4 FY2022: NA).
  

MINE DEVELOPMENT

Selinsing Gold Mine

At Selinsing, development work focused on completion of the construction and commissioning of the flotation plant at the Selinsing Gold Mine in Malaysia. The construction of the plant was completed for a total cost of $18.2 million in line with the budget.

Strategically planned construction and commissioning activities marked the progression of the project, with plant commissioning initiating a series of activities. As a result, the plant has been operating efficiently, achieving 90% of its design capacity by February 2023.

Subsequent to the year-end on September 22, 2023, the Company achieved commercial production, operating at 90% of its designed production capacity for 30 consecutive days in August 2023. During this period, the mill's availability was 94%.

Strategic pauses and resumptions in construction of the TSF and pre-stripping initiatives at Buffalo Reef were aligned with the overall project timeline.

To support continuous operations, several post-year end efforts were initiated, such as the delivery of a new drill rig and establishment of an explosive depot. In addition, enhancements to existing infrastructures, like the expansion of sample preparation facilities, were undertaken, setting the stage for future project milestones and streamlined production processes.

Murchison Gold Project

No drilling was carried out during the fourth quarter of fiscal year 2023. The Company focused on updating and reviewing drill targets at Gabanintha and has reduced exploration activities to preserve cash during the finalisation of the Selinsing sulphide plant development, noting that the costs of drilling in Western Australia have increased over 30%, due to a shortage of labour and drill rigs. The Company continues to maintain the plant and other facilities to the extent they are operationally ready for efficient commissioning when production is restarted. Site accommodation and catering facilities are fully functional to host administrative, exploration and mining activities.

Exploration

Malaysia

There was no exploration drilling undertaken at Selinsing during Q2, Q3, or Q4 of FY2023 in order to preserve cash during the final stages of the sulphide plant construction, commissioning and ramp up. Exploration activities to identify additional oxide and sulphide mineralization are expected to resume during FY2024.

Western Australia

Exploration activities were similarly reduced at the Murchison project during FY2023 in order to preserve cash during the final stages of the sulphide plant development at Selinsing and were largely limited to an ongoing review of historical maps and reports for the Gabanintha project.

Phase 2 drilling, a part of a two-year exploration plan, targeted deeper extensions in the Burnakura tenements for extended production, delivered the results confirmed gold mineralization extensions with high grades up to 17.8g/t gold, over 150m vertically below the current NOA Mineral Resource. This suggests a notable potential for Mineral Resource expansion. The findings revealed increased width, grade, and alteration at depth, indicating the NOA deposits' potential can be further tapped with focused exploration. There's emphasized potential for deeper mining in historic pits and transitioning to underground mining, with prospects extending beyond the current 1.6km limit. Key intercepts include 4m at 12.0g/t gold at NOA 7/8 and 2m at 17.8g/t gold at NOA 4-6.
