Q2 FY2023 Production Analysis

Gold Bullion Production

• Q2 FY2023 gold bullion production was 1,498oz, a 11% decrease as compared to 1,683oz for Q2 FY2022. The decrease mainly resulted from lower gold recovery.
• Q2 FY2023 ore processed decreased to 62,817t from 129,000t for Q2 FY2022. The decreased mill feed was mainly due to a significant reduction of crushed ore and mechanical and electrical problems and the transition from carbon-in-leach plant to new sulphide flotation plant tie-in.
• Q2 FY2023 cash cost per ounce decreased by 17% to $1,507/oz from $1,810/oz for Q2 FY2022. This decrease was primarily due to a significant increase in the mill feed grade from 0.56g/t Au to 1.14g/t Au and increase in gold bullion sale, less mining costs and a slight lower processing costs.
  

Gold Concentrate Production

• In December, commissioning of sulphide flotation plant commenced, and 9,574 t of flotation feed was milled, 126 dry metric tonnes of gold concentrate was produced with 177 oz gold recovered. There was no sale of gold concentrate during Q2 FY2023.
  

Overall, Q2 FY2023 average mill feed grade was 1.14g/t Au as compared to 0.56g/t Au of Q2 FY2022 due to higher grade ore from Selinsing and Buffalo Reef than Peranggih oxide mineralized materials. Q2 FY2023 processing recovery rate decreased to 39.9% from 63.2% for Q2 FY2022. The decrease in processing recovery rate was mainly due to the transition from carbon-in-leach (CIL) plant to the new sulphide flotation plant tie-in.

Q2 FY2023 Financial Analysis

• Q2 FY2023 gold bullion sales generated revenue was $5.87 million as compared to $5.05 million from Q2 FY2022. Gold sales revenue was derived from the sale of 3,350oz (Q2 FY2022: 2,150oz) of gold at an average realized gold price of $1,753 per ounce (Q2 FY2022: $1,828 per ounce) and the delivery of nil oz (Q2 FY2022: 723 oz at $1,545 per ounce gold equivalent) in fulfilling gold prepaid sale obligations.
• Q2 FY2023 total production costs decreased by 3% to $5.05 million as compared to $5.20 million from Q2 FY2022. Cash cost per ounce decreased by 17% to $1,507/oz as compared to $1,810/oz of the same period last year. The decrease was attributable to an increase in the mill feed grade from 0.56g/t to 1.14g/t, increase in gold bullion sale, less mining costs and a slight lower processing costs, offset by a decrease in recovery to 39.9% (Q2 FY2022: 63.2%).
• Gross margin for Q2 FY2023 was $0.82 million before operation expenses and non-cash amortization and accretion as compared to negative $0.15 million from Q2 FY2022. The increase in gross margin was attributable to significant higher grade ore feed, more gold sold, and decreased cash costs.
• Net loss for Q2 FY2023 was $3.20 million, or ($0.01) per share as compared to net loss of $2.50 million or ($0.01) per share from Q2 FY2022.
• Cash and cash equivalents balance as at December 31, 2022 was $12.81 million, a decrease of $8.23 million from the balance at June 30, 2022 of $21.04 million due to $10.31 million development cost in Selinsing including $9.32 million spent in sulphide project development, and $0.62 million spent in Murchison exploration and maintenance activities, and $0.02 million spent in long-term lease obligations, offset by $2.10 million generated in operation activities. As at December 31, 2022, the Company had positive working capital of $18.89 million as compared to that at June 30, 2022 of $30.33 million.
  

Development

Selinsing Gold Mine

The Selinsing sulphide project development to produce saleable sulphide gold concentrate continued in the quarter. As of December 31, 2022, 91% of the overall project has been completed with cost incurred of $15.61 million. During the second quarter of FY2023, flotation plant construction and most ancillary equipment were substantially complete and installed except for the cabling work. Plant commissioning began in November 2022. Dry and wet commissioning completed on flotation cells, concentrate and water recovery thickeners, reagents mixing and storage, blowers, compressor, and filter press plant. Ore commissioning started on December 15, 2022, ongoing improvements to flotation circuit, correcting shortfalls continued. The ramp up to full production commenced after the end of the second quarter, in January 2023.

Pre-stripping continued in the second quarter for the flotation plant. Mining of transitional and sulphide ore continued during the quarter to stockpile ore for future production.

During the second quarter of FY2023, metallurgical drilling at Buffalo Reef had commenced and completed with 508m over 12 holes. The drilling targeted representative transition and fresh sulphide samples from each of the BRC2, BRC 3, BRC 4, and BRN pits. Assay results for all 586 samples were received. The samples with a grade above 0.35g/t were composited based on oxidation category (transition and fresh) and submitted to the metallurgical laboratory at Selinsing for a series of locked cycle tests to obtain recovery and grade data for the life of mine optimisation. The overall strategy of the mine plan is to achieve maximum gold recovery and minimise arsenic and stibnite grade in concentrate.

Murchison Gold Project

No drilling was carried out during the second quarter of fiscal year 2023. The Company focused on updating and further reviewing of Gabanintha drill targets and slowed down drilling to preserve cash in supporting Selinsing development, while the costs of drilling in Western Australia are up over 30% and there are shortages in labour and drill rigs. The Company continued 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.
