The Original Filing reported the final voting results of the Company's special meeting of stockholders held on January 14, 2025 (the "Special Meeting"). The purpose of this amendment is to update the voting results reported in the Original Filing based upon an updated final report of the Inspector of Election received following the date of the Original Filing.

There were 69,470,001 shares of Common Stock of Gatos Silver outstanding and entitled to vote at the Special Meeting, of which 50,394,095 shares were present in person or represented by proxy, which represented approximately 72.6% of the shares entitled to be voted and therefore a quorum was present.
