Star Diamond Corp. Provides Litigation Update Regarding Injunction Application

SASKATOON, June 2, 2020 - Star Diamond Corp. ("Star Diamond" or the "Corporation") (TSX: DIAM) announced today that its injunction application against Rio Tinto Exploration Canada Inc. ("RTEC") is currently scheduled to be heard by the Court of Queen's Bench for Saskatchewan (Judicial Centre of Saskatoon) on June 29 and 30, 2020. The injunction application was brought by Star Diamond as part of the previously disclosed legal proceedings (the "Legal Proceedings") that Star Diamond commenced against RTEC earlier this year related to RTEC's purported exercise in November 2019 of its four options under the Option to Joint Venture Agreement dated June 22, 2017. The injunction application seeks, among other things, to restrain RTEC from calling any meeting of the management committee under the joint venture agreement between Star Diamond and RTEC that would have come into effect if RTEC had validly exercised its four options in November 2019. After the Legal Proceedings were commenced, RTEC agreed that, until the Court has rendered a decision on the injunction application, RTEC would not seek to call any meeting of such management committee.

In light of current restrictions related to COVID-19 impacting the operations of the Court, Star Diamond currently expects that the hearing of the injunction application will occur by teleconference among the parties and their respective counsel and not be accessible to the public. However, both the timing of the hearing of the injunction application and the manner in which such hearing will be conducted are subject to further order of the Court, and there is no certainty that such hearing will not be delayed or be heard in a different manner. Star Diamond expects to provide a further update once the injunction application is determined by the Court.
