The maturity date of the warrants attached to the DB CLN are eighteen months after the earlier of the date on which the Tongo-Tonguma tribute mining agreement ("Transaction") completes, or the date on which the Company makes an announcement that the Transaction will not proceed. There are no other changes to the DB CLN.

Furthermore, the Company announces an extension to the longstop date ("Transaction Default") of its US$1.34 million outstanding Convertible Loan Note with Deutsche Balaton, Creditforce and Steven Poulton ("US$1.34m CLN") to the 30 April 2018.

Stellar also announces that it has entered into an interest free unsecured loan agreement with Rowan Carr, the Company's Chief Operating Officer, for US$109,500 in relation to funds advanced by Rowan Carr for project costs incurred by the Group in Guinea whilst the recent asset disposal process was being completed ("Loan"). At present there is no fixed repayment schedule however the Company has committed to repay the Loan using the proceeds of future fundraises.

Note on Related Party Transaction

By virtue of Deutsche Balaton being a substantial shareholder and Steven Poulton being a Director of the Company the amendments to the DB CLN and the US$1.34m CLN (together the "CLNs") above constitute related party transactions under the AIM Rules for Companies. By virtue of Rowan Carr being a director of a subsidiary company of Stellar, the Loan also constitutes a related party transaction. The Directors who are independent of the CLNs and the Loan consider, having consulted with the Company's Nominated Adviser, that the amended terms of the CLNs and the Loan are fair and reasonable insofar as the Company's shareholders are concerned.
