On September 28, 2022, KPMG LLP (“KPMG”) notified Gatos Silver that it resigned as the Company’s independent registered public accounting firm. The audit committee of the Company’s board of directors accepted KPMG’s resignation. KPMG’s resignation was prompted by its conclusion that KPMG is unable to serve as the Company’s principal auditor for the year-ended December 31, 2021 due to the previously announced changes in the composition and location of our executive team based on its understanding of the Organization of Chartered Professional Accountants of British Columbia Bylaws, which would require KPMG to be licensed in British Columbia. KPMG’s audit reports on the Company’s consolidated financial statements for the years ended December 31, 2020 and 2019 do not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles. As previously disclosed, the Company is evaluating the impact on prior period financial statements of the circumstances pertaining to the previously announced determination that the Company’s mineral reserve report can no longer be relied upon. During the two most recent fiscal years and the subsequent interim period preceding KPMG’s resignation, there were no (i) disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG, would have caused it to make reference to the subject matter of the disagreements in connection with its report, or (ii) “reportable events” as such term is defined in Item 304(a)(1)(v) of Regulation S-K.

The Company is diligently working to identify and engage an auditor to conduct the audit and review of the financial statements required to be included in its annual report on Form 10-K for the year ended December 31, 2021, its quarterly report on Form 10-Q for the quarter ended March 31, 2022 and its quarterly report on Form 10-Q for the quarter ended June 30, 2022. The Company intends to file such SEC reports as soon as practicable and expects to hold its annual shareholder meeting once such reports have been filed. While the Company is continuing to evaluate material weaknesses in its internal controls over financial reporting related to the mineral reserve reporting errors, the Company expects that it will determine that at least one material weakness exists. The Company is still evaluating the extent of this and other potential material weaknesses. The Company’s financial statements for the year ended December 31, 2021 and quarters ended March 31, 2022 and June 30, 2022 may be affected by the ongoing analysis of the aforementioned mineral reserve matters.

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; (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 default announced in the Notice.
