("Petra" or the "Company")

Initial Sales Results for 80% ofFourth Tender cycle for FY 2022

Petra has closed sales for approximately 80% of the volume of its Fourth Tender cycle for FY 2022.  In these initial tender results, 589,168 carats have been sold for a total of US$110.5 million, at an average price of US$188 per carat. No Exceptional Stones were sold as part of these initial sales.

Like-for-like rough diamond price increases on the six months to December 2021 are still being determined and will be announced when they become available.  As a result, it is not yet possible to determine how much of the increase in US$ price per carat is attributable to market movement versus product mix.

The sale of the remaining 20% of the volume of the Fourth Tender cycle, which is of comparable product mix, is scheduled to close on or around 7 March 2022 and the full sales results of the Fourth Tender cycle will be released shortly thereafter.

This announcement includes inside information as defined in Article 7 of the Market Abuse Regulation No. 596/2014 and is being released on behalf of Petra by the Company Secretary.

About Petra Diamonds Limited
