Recovery of Five High Quality Blue Diamonds

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION

FOR IMMEDIATE RELEASE

16 September 2020 LSE: PDL

Petra Diamonds Limited

(“Petra”, “the Company” or “the Group”)

Recovery of Five High Quality Blue Diamonds at the Cullinan Mine

Update on Discussions with Financial Stakeholders

Petra Diamonds Limited announces that it has recovered five Type IIb blue diamonds of high quality in terms of both their colour and clarity at the Cullinan mine in South Africa. The diamonds are also significant in terms of their size, being 25.75, 21.25, 17.57, 11.42 and 9.61 carats, and are assessed to be individual stones and not originally part of one larger diamond.

Blue diamonds are so rare that there are no official statistics on their recovery, however the Cullinan mine is known as the world’s most important source. The last blue diamond of significance was recovered a year ago at the mine in September 2019 and it is therefore even more unusual to recover five high quality stones around the same time, all in the space of one week’s production.

Given the challenges presented by the COVID-19 pandemic, the Company is maintaining a flexible approach to sales. It is therefore still evaluating the optimal route to market for the stones and the Company will release further information to its customer base on the marketing plan in due course.

Petra continues to undertake discussions with the Ad Hoc Group of holders of the Group's Senior Secured Second Lien Notes (“AHG”) and also with the South African lender group regarding a long term solution to improve the Group's capital structure. The Company will make a further announcement in relation to these discussions in due course. While the Company continues to have constructive engagement with the AHG and the lender group, there can be no certainty that these discussions will result in agreement being reached.

In addition, these finds, whilst a positive development, will not have a material impact on the likely terms of the required long term solution to improve the Group's capital structure, nor the  significant level of equity dilution that existing shareholders are likely to experience in connection with its implementation.
