EY will be auditing and reporting on the Company's consolidated financial statements for the financial years ended December 31, 2021 and December 31, 2022 and will be reviewing the Company's quarterly unaudited interim financial information for 2022. The Company expects all delayed filings, including the audit of the financial statements required to be included in its annual report on Form 10-K for the year ended December 31, 2021, and the reviews of its quarterly reports on Forms 10-Q for the quarters ended March 31, 2022, June 30, 2022 and September 30, 2022, to be completed before the end of the first quarter of 2023.

As previously disclosed, in connection with its ongoing review of the mineral reserve reporting errors and its preparation of its 2021 annual financial statements and 2022 interim financial statements, the Company has identified material weaknesses in its internal controls over financial reporting. The Company has determined that the material weaknesses relate to its failures to design and maintain (i) an effective control environment commensurate with the financial reporting requirements of a public company in the United States and Canada, and (ii) effective controls over the assessment of certain key assumptions, inputs and outputs contained in its 2020 Technical Report. The Company is continuing to assess the impact of these material weaknesses and whether any other material weaknesses exist. On January 9, 2023, the Company engaged a third-party expert to assist management in documenting key processes related to the Company's internal control environment, designing and implementing an effective risk assessment and monitoring program to identify risks of material misstatements and ensuring that the internal controls have been appropriately designed to address and effectively monitor identified risks. The Company expects to provide additional information in its upcoming public reports.

A management cease trade order was granted by the Ontario Securities Commission on April 1, 2022 (the "Original MCTO") and the Ontario Securities Commission granted additional management cease trade orders on April 12, 2022 and July 7, 2022 (the "Additional MCTOs" and together with the Original MCTO, the "MCTO").

Pursuant to NP 12-203, the Company must file bi-weekly status reports in the form of further news releases during the period from the Notice until the MCTO is revoked. The Company reports that since the Notice: (i) there have been no material changes regarding the information contained in the Notice that have not been disclosed in a bi-weekly default status report or in a news release referenced therein; (ii) there have been no failures by the Company in fulfilling its stated intentions with respect to satisfying the provisions of the alternative information guidelines under NP 12-203; and (iii) there has not been any specified default subsequent to the defaults announced in the Notice and the news releases dated May 13, 2022, August 5, 2022 and November 11, 2022.
