SASKATOON, Saskatchewan, February 22, 2021 – Star Diamond Corporation (“Star Diamond” or the “Corporation”) today announced that Rio Tinto Exploration Canada Inc. (“Rio Tinto Canada”) has provided written notice that it has now successfully completed the ten cutter hole bulk sample program excavated by Rio Tinto Canada in 2019 at the Star – Orion South Diamond Project (the “Project”). Rio Tinto Canada has confirmed to Star Diamond that this bulk sample program met Rio Tinto Canada’s objective of improving confidence in the diamond grade of the Project. In a letter written to Star Diamond’s Chair of the Board, Rio Tinto Canada stated:
“I am pleased to report to Star Diamond Corporation (SDC) that Rio Tinto Exploration Canada Inc. (RTEC) has as of today completed the quality assurance and quality control (QA/QC) procedures allowing RTEC to accept the final processing and recovery results of the Star ten bulk sample programme reported by the Saskatchewan Research Council (SRC) to the participants. I am even more pleased that those results have met the objective of the Star bulk sampling programme, which was to improve confidence in the grade of the Star Kimberlite. I enclose the report which documents the main QA/QC procedures performed and explains why we are able accept the certified results reported by SRC.
RTEC has now completed the processing, diamond recovery and reporting of all diamond results on the samples previously taken from the 10 cutter holes completed in 2019 on the Star Kimberlite. We are proud to have completed this work in accordance with industry standards and to have done so in the middle of the global COVID-19 pandemic.”
Star Diamond has written to Rio Tinto Canada to advise that completion of a comprehensive diamond breakage study and certain other work remain outstanding. Star Diamond has reminded Rio Tinto Canada that, until the comprehensive diamond breakage study and that other work is completed, the processing, diamond recovery and reporting of all diamond results from the ten cutter hole bulk sample program will not be complete. Rio Tinto Canada has previously assured Star Diamond that a comprehensive diamond breakage study would be completed by Rio Tinto Canada as part of the bulk sample program.
“Star Diamond remains pleased with the results to date from Rio Tinto Canada’s bulk sampling program, which have confirmed Star Diamond’s belief that the Project has excellent geology with large and contiguous diamond-bearing kimberlites with a high proportion of valuable Type IIa stones,” said Ken MacNeill, President and CEO of Star Diamond. “However, contrary to its prior assurances to Star Diamond, Rio Tinto Canada has not yet completed a comprehensive diamond breakage study. This study is required to properly assess the full nature, extent and potential causes of the undue diamond breakage that appears to have resulted from Rio Tinto Canada’s use of unproven and inadequately tested extraction and/or diamond recovery methodologies, and the extent to which larger diamonds would have been recovered in the absence of such breakage.”
As previously disclosed by Star Diamond, Rio Tinto Canada provided an undertaking (“Undertaking”) to the Court of Queen’s Bench for Saskatchewan (Judicial Centre of Saskatoon) (the “Court”), which is referred to in its August 10, 2020 decision, in ongoing litigation between Star Diamond and Rio Tinto Canada (the “Legal Proceedings”). The Undertaking is binding on Rio Tinto Canada.
As the Undertaking is described by the Court in its August 10, 2020 decision, Rio Tinto Canada agreed that it would not call and/or conduct any meeting of the management committee under the joint venture agreement (the “Joint Venture Agreement”) between Star Diamond and Rio Tinto Canada for a period of 120 days following Rio Tinto Canada completing the processing, diamond recovery and reporting of all diamond results on the samples previously taken from the ten bulk sample trenches excavated by Rio Tinto Canada in 2019.
Consistent with the Undertaking, Star Diamond has advised Rio Tinto Canada that, until all processing, diamond recovery and reporting of all diamond results from the ten cutter hole bulk sample program is completed, including the comprehensive diamond breakage study, the 120-day period under the Undertaking cannot begin to run. Notwithstanding that the comprehensive diamond breakage study has not been completed, Rio Tinto Canada advised Star Diamond on February 8, 2021 that the 120-day period commenced on that date, and that Rio Tinto Canada intends to call a management committee meeting under the Joint Venture Agreement once the 120-day period has elapsed. Rio Tinto Canada claims the completion of the comprehensive diamond breakage study that it previously said would be undertaken is not required by the Undertaking it has given.
Star Diamond will vigorously resist any attempt by Rio Tinto Canada to call a management committee meeting other than in compliance with the Undertaking. This includes completion of the comprehensive diamond breakage study before the 120-day period under the Undertaking commences to run. If necessary, Star Diamond will apply to the Court to enforce the Undertaking.
Star Diamond also announced today that the Court has directed that the next step in the previously disclosed Legal Proceedings that Star Diamond commenced against Rio Tinto Canada in 2020, namely the delivery by each of Rio Tinto Canada and Star Diamond to the other of their respective affidavits of documents, must be completed by March 15, 2021. Once this step occurs, Star Diamond expects that the parties will agree to a timetable for the completion of the other principal pre -trial steps, including oral questioning and the exchange of expert reports, which Star Diamond hopes will be completed during 2021. Once the pre-trial steps are completed, Star Diamond expects that the Court will schedule a pre-trial conference and set a date for trial. Given recent guidance from the Court, including the Court’s view that the pace of the Legal Proceedings so far has been appropriate in all of the circumstances, Star Diamond does not expect that the trial will occur in 2021.
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 on the Legal Proceedings as developments warrant.
