Q3 FY 2024 Operating Update and Final Sales Results for Tender 5 FY 2024

Richard Duffy, Chief Executive Officer of Petra, commented:

“Production for the quarter is consistent with the preceding quarter and in-line with expectations. At Finsch, the first of the 78-Level Phase II production tunnels was successfully commissioned in March 2024, with commissioning of the remaining six tunnels expected to be completed by June 2024. We confirm our FY 2024 production guidance of 2.75 – 2.85 Mcts.

Our fifth tender cycle yielded US$49 million from the sale of 362kcts. Average prices per carat received were 22% higher than Tender 4, supported by the sale of a 14.76ct exceptional colour and clarity blue diamond for US$8.2 million. Like-for-like1 prices were relatively flat through this seasonally weaker period, being 0.8% lower than Tender 4.

We continue to update our life of mine plans to support our transition to a smoother capex profile. This includes a replanned ramp-up of the deferred capital projects from Q1 FY 2025.

On 8 April 2024, we announced the signing of a definitive transaction agreement for the sale of Koffiefontein which is expected to result in Petra avoiding closure-related costs of US$15-18 million included in the Company’s 31 December 2023 balance sheet provisions. We also announced an increased cost savings target of more than US$30 million per annum that will sustainably lower our cost base. Around half of these savings are expected to come through a rebasing of fixed and variable costs in-line with reduced throughput at Finsch, with the remaining half as savings across operating costs and overheads at the Group level and Cullinan Mine.

During the quarter we repaid US$23m of our RCF to reduce interest costs and had available liquidity of US$104 million at the end of Q3 FY 2024. While net debt had increased at the end of Q3 FY 2024, proceeds from the recently-closed Tender 5 have more than offset this increase. Together with the actions taken to sustainably reduce costs, this further enhances our business resilience.”

[1] Like-for-like refers to the change in realised prices between tenders and excludes revenue from all single stones and Exceptional Stones, while normalising for the product mix impact

Highlights vs Q2 FY 2024

LTIFR and LTIs are 0.20 and 3 respectively (Q2 FY 2024: 0.18 and 3 respectively)

Ore processed reduced marginally to 2.9Mt from 3.0Mt with the continued ramp-up of production at Williamson and a steady quarter at Cullinan Mine offset by lower volumes at Finsch due to the previously announced winder issues, which have since been resolved

The 18% improvement in grades at Finsch is largely ascribed to first production tonnes from 78-Level Phase II

Lower diamond production at Cullinan Mine is due to reduced tailings volume and grade variations, in-line with expectations

Revenue amounted to US$66 million (Q2 FY 2024: US$90 million) with the decrease due to the lower production and the timing of receipts from Tender 5

Support from South African Rand weakness continued throughout the period, with the Rand averaging ZAR18.95:US$1 (Q2 FY 2024: ZAR18.99:US$1)

Capital expenditure for Q3 FY 2024 totalled US$15 million, in-line with updated guidance announced earlier following the decision to defer certain capital project expenditure

Partial settlement of the withdrawn amounts under the ZAR1.75 billion (US$93 million) Revolving Credit Facility with Absa Bank, leaving an outstanding balance of ZAR450 million (US$24 million) at 31 March 2024, down from ZAR850 million (US$47 million) at 31 December 2023

Consolidated net debt increased to US$232 million as at 31 March 2024 (31 December 2023: US$212 million) due to the timing of closing Tender 5, noting the balance of sales receipts yielded US$32 million shortly after period-end which exceeded the increase in net debt

Final sales results for Tender 5 FY 2024

The sales of the fifth tender cycle of FY 2024 closed this week with 362kcts sold yielding US$49 million, with average prices increasing 22% over Tender 4, noting a marginal 0.8% decrease in like-for-like prices. Around 48kcts of Tender 5 goods were sold in Q3 FY 2024 yielding some US$17 million.

These results include a 14.76ct exceptional colour and clarity blue gemstone recovered from the Cullinan Mine which the Company sold into a partnership agreement with sale proceeds of US$8.2 million.

Rough diamond sales results for the respective periods are set out below:

Note 1: Exceptional Stones are defined as rough diamonds for US$15 million or more each.

Sales

Total revenue YTD FY 2024 from rough diamond sales is US$285 million, compared to US$316 million in the first five tenders of FY 2023, excluding Koffiefontein. Year-on-year volume variances were affected by the deferral of certain FY 2023 sale parcels sold as part of Tender 1 of FY 2024.

Mine by mine average prices for the respective periods are set out in the table below:

Like-for-like prices

Like-for-like rough diamond prices decreased marginally by 0.8% on Tender 4 FY 2024. Prices for plus 2ct goods remained solid, while prices for smaller goods showed some seasonal weakness contributing to the overall decline. Average like-for-like prices for the first five tenders of FY 2024 were down 8.5% year-to-date compared to the equivalent five tenders of FY 2023. Pricing assumptions for the remainder of the year remain unchanged.

Product Mix

The balance of price movements is attributable to product mix, with Cullinan Mine benefiting from the 14.76ct blue stone which sold for US$8.2 million in this cycle. Williamson’s average price was impacted by reduced prevalence of higher-valued single stones, ascribed to the mining areas currently accessed and expected to be temporary in nature.

Operating Summary

2 Petra classifies “Exceptional Stones” as rough diamonds which sell for US$15 million or more each

3 Re-presented to exclude Koffiefontein which is classified as a discontinued operation

Recorded at the lower of cost and net realisable value.

Post period-end, the Company completed the balance of Tender 5 with the sale of 314,439 carats from Cullinan Mine and Finsch, yielding US$32 million which will be recorded in Q4 FY 2024.

The 2026 Loan Notes, originally issued following the capital restructuring (the “Restructuring”) completed during March 2021, have a carrying value of US$256 million which represents the outstanding principal amount of US$210 million (after the debt tender offers as announced in September and October 2022) plus US$54 million of accrued interest and is stated net of unamortised transaction costs capitalised of US$8 million.

Bank loans and borrowings represent the Group’s upsized ZAR1.75 billion (US$93 million) revolving credit facility. In December 2023, the Group announced that Absa Bank had approved an increase in the commitments under the Group’s revolving credit facility by ZAR750 million, bringing the total commitments under the facility to ZAR1.75 billion (US$93 million). This increase in the facility is now fully available following execution and completion of the associated amendment agreement on 15 February 2024. The amended facility’s existing covenants, margin, fees, and maturity date remain unchanged. A total of ZAR450 million (US$24 million) is currently drawn leaving a further balance of ZAR1.3 billion (US$69 million) available for drawdown under the upsized facility.

Consolidated Net Debt is bank loans and borrowings plus loan notes, less cash and diamond debtors.
