Gatos Silver Announces Re-Instatement and Extension of US$50 Million Revolving Credit Facility

Gatos Silver Inc. (NYSE/TSX: GATO) ("Gatos Silver" or the "Company") is pleased to announce that it has extended the maturity date and re-established a credit limit of US$50 million in an amended and restated revolving credit facility (the "Revolver") with Bank of Montreal ("BMO"). The Revolver includes an accordion feature providing up to an additional US$25 million of credit (the "Accordion").

The Revolver is available for general corporate purposes, working capital, acquisitions, and investments. In view of its strong cash position, the Company made a US$4 million repayment prior to closing. The current balance outstanding on the Revolver is US$9 million with US$41 million available for advance.

"The revised facility provides Gatos Silver with further financial flexibility as we continue to execute on our exploration and growth strategy to further maximize shareholder value, both within and beyond the Los Gatos district," said Dale Andres, CEO of Gatos Silver. "It represents a clear vote of confidence from our lender in the quality of Gatos Silver's assets, its updated mineral reserves and mineral resources, and its new management team."

André van Niekerk, the Company's CFO commented: "We are pleased with the re-instatement and extension of the Revolver with BMO and would like to thank our lender for its continued support. Our net cash position continued to improve quarter over quarter during 2022 and with the amendment of the Revolver, the Company is in a very strong financial position with sufficient liquidity to pursue its value creation catalysts."

Key terms of the amended Revolver include:

• US$50 million revolving line of credit with an accordion feature, which allows for an increase in the total line of credit up to US$75 million, subject to certain conditions.
• The maturity date is extended from July 31, 2024 to December 31, 2025.
• A change in the benchmark interest rate from LIBOR to the Secured Overnight Financing Rate ("SOFR").
• Loans under the Revolver bear interest at a rate equal to either a term SOFR rate plus a margin ranging from 3.00% to 4.00% or a U.S. base rate plus a margin ranging from 2.00% to 3.00%, as selected by the Company.

There were no other material changes to the terms of the original Revolver dated July 12, 2021. Availability under the Revolver was previously reduced to US$30 million on March 8, 2022.
