Properties of the Original Filing; (ii) revise the disclosure regarding our disclosure controls and procedures in Part II, Item 9A. Controls and Procedures of the Original Filing to reflect management’s conclusion that the Company’s disclosure controls and procedures were not effective at June 30, 2022 solely as a result of the updated disclosures responding to Item 601(b)(96) and subpart 1300 of Regulation S-K included in this Amendment No. 1; and (iii) file the Company’s 2020 Technical Report Summary (as defined below) as Exhibit 96.1 to this Amendment No. 1.

Exhibits and Financial Schedules of the Original Filing to include, among other items, the filing of new certifications of the Company’s Chief Executive Officer and Chief Financial Officer pursuant to Rule 13a-14(a) as Exhibits 31.1 and 31.2, as well as third-party consents for the 2020 Technical Report Summary in Exhibit 23.1. Except as described above, this Amendment No. 1 does not amend, update or change any other information set forth in the Original Filing (including in the consolidated financial statements included therein) and does not reflect or purport to reflect any information or events occurring after the original filing date or modify or update those disclosures affected by subsequent events. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and the Company’s other filings with the SEC. This Amendment No. 1 consists solely of the preceding cover page, this explanatory note, Part I, Item 2. Properties, Part II, Item 9A. Controls and Procedures, Part IV, Item 15.
