Star Diamond Update on Legal Dispute with Rio Tinto Canada

Stock Symbol: DIAM: TSX 

SASKATOON, SK, June 21, 2021 /CNW/ - Star Diamond Corporation ("Star Diamond") today provided an update on the ongoing litigation (the "Legal Proceedings") between Star Diamond and Rio Tinto Exploration Canada Inc. ("Rio Tinto Canada") in the Court of Queen's Bench for Saskatchewan (Judicial Centre of Saskatoon) (the "Court").

As previously disclosed, on June 4, 2021, the Court held a hearing in respect of the undertaking (the "Undertaking") previously provided by Rio Tinto Canada to the Court.  The Court reserved its decision, which is expected in the coming weeks. 

Notwithstanding that the Court has not yet released its decision in respect of the Undertaking, on June 17, 2021, Rio Tinto Canada delivered a notice to Star Diamond purporting to call, for July 21, 2021, a meeting of the management committee of the joint venture that Rio Tinto Canada claims was previously formed between Star Diamond and Rio Tinto Canada. As previously disclosed, Star Diamond believes that no such joint venture has been formed because Rio Tinto Canada's November 2019 purported exercise of its options under the Option to Joint Venture Agreement dated June 22, 2017 between Star Diamond and Rio Tinto Canada did not comply with that agreement.

The June 17, 2021 notice from Rio Tinto Canada indicates that Rio Tinto Canada will be seeking approval of a proposed budget for the period from June 2021 to March 2022 of Cdn. $17.8 million.  The notice also indicates that Rio Tinto Canada will be seeking to add to that budget an aggregate of Cdn. $64.4 million allegedly spent by Rio Tinto Canada during 2019, 2020 and the first five months of 2021.

Star Diamond disagrees with the positions taken by Rio Tinto Canada in the June 17, 2021 notice.  However, out of respect for the pending Court decision in relation to the Undertaking, Star Diamond currently intends to wait for the release of that decision before responding to such notice.

Star Diamond continues to vigorously pursue the Legal Proceedings and is committed to taking all actions necessary to protect Star Diamond and its shareholders from the practices and conduct of Rio Tinto Canada. Star Diamond will provide further updates in respect of these matters as developments warrant.
