Stellar Diamonds plc

("Stellar" or the "Company")

 Amendments to Convertible Loan Notes

Stellar Diamonds plc, the London listed diamond development company focused on West Africa, announces that it has negotiated a two month extension to the longstop dates with the noteholders ("Noteholders") of its two outstanding Convertible Loan Notes ("CLNs"). Details of the CLNs are contained in the announcements by the Company of 2 November 2015, 6 October 2016 and 24 February 2017 and in particular, the two month extension relates to the longstop dates referred to in the announcement of 24 February 2017.

Chief Executive Karl Smithson commented:

"Stellar is undergoing a transformation from an explorer to a mine developer. I would like to thank the Noteholders for their continued support as we progress towards the commercial development of the 4.5million carat Tongo-Tonguma underground kimberlite diamond mine in Sierra Leone. We have made key advances in recent weeks in terms of signing the binding Tribute Mining Agreement and signing the contract for the Front End Engineering and Design for the initial mine development. With a low capex requirement of US$32 million, the proposed Tongo-Tonguma mine has the potential to be the second largest kimberlite diamond mine in West Africa, with forecast production levels of 200,000 carats per annum, generating revenues of over US$45 million per annum over a minimum life of mine of 21 years. I look forward to updating shareholders on our progress."

Note on Related Party Transaction

For the avoidance of doubt, other than as set out in this announcement, all other terms of the CLNs remain in force. By virtue of Deutsche Balaton being a substantial shareholder of the Company and Steven Poulton being a non-executive Director of the Company, the amendments above constitute related party transactions under the AIM Rules for Companies. The Directors who are independent of the CLNs and associated warrants consider, having consulted with the Company's Nominated Adviser, that the amended terms of the CLNs are fair and reasonable in so far as the Company's shareholders are concerned.
