("Petra" or "the Company")

Final sales results for Tender 3 FY 2024 and Notice of Investor Presentation

Further to the announcement on 8 December 2023 of Petra's initial sales results for Tender 3, the Company today announces the final sales results for its third tender cycle following further sales of 56.6 kcts for US$9.3 million which brings total sales for this cycle to US$67.9 million from 519.4 kcts sold. The final sales results delivered a 19.3% increase in like-for-like[1] prices compared to Tender 2 FY 2024 which closed in October 2023, reaffirming Petra's belief that diamond prices have likely bottomed.

Petra's Senior Management will host an investor presentation on 18 December 2023 to discuss recent company updates and the diamond market. Details can be found at the bottom of the release.

Rough diamond sales results for the respective periods are set out below1:

Note 1: Excludes all Koffiefontein sales results since it has been classified as a discontinued operation in the Group's FY 2023 accounts.

Note 2: Exceptional Stones are defined as rough diamonds for US$15 million or more each.

Sales

A further 25.2 kcts of goods from Cullinan Mine and Finsch were sold, yielding US$3.1 million, while a shipment from Williamson containing 31.4 kcts was sold for US$6.2 million.

Total revenue YTD FY 2024 from rough diamond sales is US$187.8 million, compared to US$202.8 million in the first three tenders of FY 2023, excluding Koffiefontein. Year-on-year volume variances were affected by the deferral of certain FY 2023 sale parcels, which were 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 for goods sold improved by 19.3% on Tender 2 FY 2024, driven by over 20% increases in prices achieved for goods smaller than 2 cts, while 2 to 10.8 ct parcels saw increases in the mid-teens. Year to date like-for-like prices are down 13.3% compared to the equivalent three tenders of FY 2023.

Product mix

The balance of price movements is attributable to product mix, with an improved contribution from higher-value single stones from Cullinan Mine, including a 12.6ct blue stone that sold for US$6.2 million and was included in the initial sales results, while Finsch and Williamson saw marginally reduced overall qualities in their product offering, although both remained within the expected range of product variability.
