Specifically, the SEC Statement clarified guidance for all SPAC-related companies regarding the accounting and reporting for their warrants and focused in part on provisions in warrant agreements that provide for potential changes to the settlement amounts dependent upon the characteristics of the warrant holder, and because the holder of such warrants would not be an input into the pricing of a fixed-for-fixed option on equity shares, such provision would preclude such warrants from being classified in equity and thus such warrants should be classified as a liability.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As previously disclosed in the Company's Annual Report on Form 10-K/A, as filed on May 14, 2021 (“2020 Form 10-K/A”), the Company restated its previously issued consolidated financial statements and accompanying notes as of and for the year ended December 31, 2020, to make the necessary accounting corrections related to warrant accounting and to recognize certain warrants as a liability instead of as equity, in accordance with Accounting Standards Codification (“ASC”) 815-40, </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Contracts in Entity’s Own Equity</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">.

Historically, the commodity markets have been very volatile, and there can be no assurance that commodity prices will not be subject to wide fluctuations in the future. A substantial or extended decline in commodity prices could have a material adverse effect on the Company’s financial position, results of operations, cash flows, access to capital and the quantities of mineral reserves that the Company can economically produce. </span></div>In addition to changes in commodity prices, other factors such as changes in mine plans, increases in costs, geotechnical failures, changes in social, environmental or regulatory requirements, taxation policies, the ability to successfully implement new technologies for processing ore, timely financing for development, impacts of global events such as the COVID-19 pandemic, and management’s decision to expand production to commercial levels can adversely affect the Company’s ability to recover its investment in certain assets and result in impairment charges.

The more significant areas requiring the use of management estimates and assumptions relate to: recoverable gold and silver ounces on stockpiles, leach pads and in-process inventories; timing of near-term ounce production and related sales; the useful lives of long-lived assets; probabilities of future expansion projects; estimates of mineral reserves; estimates of life-of-mine production timing, volumes, costs and prices; current and future mining and processing plans; environmental reclamation and closure costs and timing; deferred taxes and related valuation allowances; estimates of the fair value of liability classified warrants, and estimates of fair value for asset impairments and financial instruments. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable at the time the estimate is made. Actual results may differ from amounts estimated in these financial statements, and such differences could be material. Accordingly, amounts presented in these financial statements are not indicative of results that may be expected for future periods.</span></div>
