Gatos Silver Reports First Quarter 2024 Results and Announces Investor Call

VANCOUVER, May 06, 2024 - Gatos Silver Inc. (NYSE/TSX: GATO) ("Gatos Silver" or the "Company") today announced its first quarter 2024 financial and operating results. The Company will host an investor and analyst call on May 7, 2024, details of which are provided below.

The Company has a 70% interest in the Los Gatos Joint Venture ("LGJV"), which in turn owns the Cerro Los Gatos ("CLG") mine in Mexico. Production for the first quarter of 2024 was previously disclosed on April 9, 2024. The Company's reporting currency is US dollars.

Dale Andres, CEO said: "During the first quarter we continued to add cash to the balance sheet mainly because of the previously disclosed strong operational performance at the LGJV. All-in sustaining cost ("AISC") per silver ounce was at the lower end of 2024 guidance thanks to improved operating efficiencies, which helped to offset inflationary cost pressures and the impact of the stronger Mexican peso."

"We now expect full year 2024 silver and silver equivalent production to be in the top half and AISC to be in the lower half of our previously announced guidance ranges. We also continue to advance our growth initiatives. Conversion drilling of the South-East Deeps inferred resource to extend mine life progressed well during the quarter and the LGJV has started ramping-up exploration efforts on near-mine and other targets in the highly prospective Los Gatos district."

Summary

LGJV Q1 2024 results compared to Q1 2023 (100% basis):

• Revenue of $72.2 million, up 3% from $69.9 million

At the LGJV, higher sales volumes compared to Q1 2023 helped to drive higher revenue, partially offset by lower realized metal prices due to final settlement adjustments on sales. There was also a significant provisional revenue adjustment in the comparable quarter in 2023.

For Gatos Silver, higher net income, earnings per share and EBITDA¹ for Q1 2024 were primarily attributable to the higher equity income from the LGJV, partially offset by an increase in general and administrative expenses including higher legal expenses which are not expected to be recurring beyond 2024. Other G&A expenses were also higher due to non-cash items, including stock-based compensation of $1.7 million. The change in operating cash flow and increase in free cash flow¹ was primarily a result of the capital distribution received in Q1 2024. Capital distributions are now shown on the cash flow statement as cash flow received from operating activities, consistent with how cash dividends from the LGJV were treated in 2022.

As of March 31, 2024, the Company had a cash balance of $70.6 million, up 27% from $55.5 million at the end of 2023. The increase in cash during the quarter was due to receipt of a $21.0 million capital distribution.

Subsequent to quarter end, the LGJV made a capital distribution on April 22, 2024, to its partners of $25.0 million of which the Company received $17.5 million. Also, during March and April the full amount of funding to settle the class action lawsuits in both the US and Canada was placed into escrow accounts, of which the Company's share was $4.0 million, with the remainder, $20.0 million, funded by our insurers.

As of April 30, 2024, the Company had a cash balance of $85.4 million and the LGJV had a cash balance of $20.0 million. The Company continues to be debt free with $50.0 million available under the revolving credit facility.

2024 Guidance Update (CLG 100% basis)

Gatos Silver expects plant throughput in 2024 to average in the top half of our previously announced guidance range of 3,000 and 3,300 tonnes processed per day. This compares to 2,935 tonnes per day in 2023. The LGJV continues to strive to achieve sustainably higher plant throughput rates as mine debottlenecking efforts continue with a medium-term target to sustain 3,500 tonnes per day beyond 2024, or 40% above original design capacity.

As a result of strong plant throughput performance anticipated in 2024, both silver and silver equivalent production is now expected to be in the top half of our previously announced guidance ranges of 8.4 to 9.2 million ounces and 13.5 to 15.0 million ounces respectively.

The Company expects full year co-product and by-product AISCs to remain in the lower half of our original guidance ranges of $14.00 to $16.00 per ounce of payable silver equivalent and $9.50 to $11.50 per ounce of payable silver.

The Company continues to expect sustaining capital expenditures at CLG (100% basis) to be approximately $45 million in 2024, the majority of which is for underground development primarily to access the lower levels of the NW and Central zones and to further develop access to the SE zone. The expected expenditures also include projects to help improve operating efficiencies and to support debottlenecking efforts in the mine.

There is no change to anticipated exploration and definition drilling expenditures of $18 million in 2024, of which $9 million is expected to be capitalized and incurred on resource development drilling primarily in the SE Deeps zone and $9 million expensed and incurred on greenfields exploration. The focus in the first quarter was primarily on continuing to infill the SE Deeps zone to approximately 50 metre spacing for the 2024 mineral resource and mineral reserve update anticipated to be announced in the third quarter of 2024. The focus for the surface drilling rigs is now shifting to other district targets. Drill testing of near mine targets at Portigueño is already underway and drilling at the NW Deeps target is expected to commence this month. San Luis and Lince are expected to be drilled later in the year.

Restatement of Previously Issued Interim and Annual Financial Statements

During preparation of the financial statements for the current quarter, we determined that an accounting classification change was required for the capital distributions received from our investment in affiliate in our consolidated statements of cash flows in 2023. The capital distributions we received should have been classified as "cash provided by operating activities" rather than "cash provided by investing activities" in our condensed consolidated financial statements for the three and nine months ended September 30, 2023, and our consolidated financial statements for the year ended December 31, 2023.

The reclassifications on our consolidated statements of cash flows do not impact our consolidated balance sheets, consolidated statements of income and comprehensive income and consolidated statements of stockholders' equity, as of and for the periods ended September 30, 2023, and December 31, 2023. The reclassifications also have no effect on our business operations, cash balances or liquidity or the financial statements of the Los Gatos Joint Venture.

On May 6, 2024, we filed an amended Quarterly Report on Form 10-Q/A for the three and nine months ended September 30, 2023, and an amended Annual Report on Form 10-K/A for the year ended December 31, 2023, which restate the consolidated statements of cash flows to correct this misclassification, and revise certain related information, including management discussion and analysis and the discussion of our internal controls and procedures. For further details, refer to the Form 8-K filed on May 6, 2024, on both the EDGAR and SEDAR+ systems.

About Gatos Silver

Gatos Silver is a silver dominant exploration, development and production company that discovered a new silver and zinc-rich mineral district in southern Chihuahua State, Mexico. As a 70% owner of the Los Gatos Joint Venture ("LGJV"), the Company is primarily focused on operating the Cerro Los Gatos mine and on growth and development of the Los Gatos district. The LGJV includes approximately 103,000 hectares of mineral rights, representing a highly prospective and under-explored district with numerous silver-zinc-lead epithermal mineralized zones identified as priority targets.

Qualified Person

Scientific and technical disclosure in this press release was approved by Anthony (Tony) Scott, P.Geo., Senior Vice President of Corporate Development and Technical Services of Gatos Silver who is a "Qualified Person" as defined in S-K 1300 and NI 43-101.

Non-GAAP Financial Measures

We use certain measures that are not defined by GAAP to evaluate various aspects of our business. These non-GAAP financial measures are intended to provide additional information only and do not have any standardized meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP.

Cash Costs and All-In Sustaining Costs

Cash costs and all-in sustaining costs ("AISC") are non-GAAP measures. AISC was calculated based on guidance provided by the World Gold Council ("WGC"). WGC is not a regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements. Other mining companies may calculate AISC differently as a result of differences in underlying accounting principles and policies applied, as well as definitional differences of sustaining versus expansionary (i.e. non-sustaining) capital expenditures based upon each company's internal policies. Current GAAP measures used in the mining industry, such as cost of sales, do not capture all of the expenditures incurred to discover, develop and sustain production. Therefore, we believe that cash costs and AISC are non-GAAP measures that provide additional information to management, investors and analysts that aid in the understanding of the economics of the Company's operations and performance compared to other producers and provides investors visibility by better defining the total costs associated with production.

Cash costs include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, treatment and refining costs, general and administrative costs, royalties and mining production taxes. AISC includes total production cash costs incurred at the LGJV's mining operations plus sustaining capital expenditures. The Company believes this measure represents the total sustainable costs of producing silver from current operations and provides additional information of the LGJV's operational performance and ability to generate cash flows. As the measure seeks to reflect the full cost of silver production from current operations, new project and expansionary capital at current operations are not included. Certain cash expenditures such as exploration, new project spending, tax payments, dividends, and financing costs are not included.

EBITDA

Management uses earnings before interest, income tax, depreciation, depletion and amortization ("EBITDA") to evaluate the Company's operating performance, to plan and forecast its operations, and assess leverage levels and liquidity measures. The Company believes the use of EBITDA reflects the underlying operating performance of our core mining business and allows investors and analysts to compare results of the Company to similar results of other mining companies. EBITDA do not represent, and should not be considered an alternative to, net income or cash flow from operations as determined under GAAP.

Free Cash Flow

Management uses free cash flow as a non-GAAP measure to analyze cash flows generated from operations. Free cash flow is cash provided by (used in) operating activities less cash flow from investing activities as presented on the consolidated statements of cash flows. The Company believes free cash flow is also useful as one of the bases for comparing the Company's performance with its competitors. Although Free Cash Flow and similar measures are frequently used as measures of cash flows generated from operations by other companies, the Company's calculation of free cash flow is not necessarily comparable to such other similarly titled captions of other companies.

Reconciliation of GAAP to non-GAAP measures

The table below presents a reconciliation between the most comparable GAAP measure of the LGJV's expenses to the non-GAAP measures of (i) cash costs, (ii) cash costs, net of by-product credits, (iii) co-product AISC and (iv) by-product AISC for our operations.

¹ Exploration costs are not related to current operations.
² Represent reductions on customer invoices and included in Sales of the LGJV combined statement of income (loss).
³ Sustaining capital excludes resource development drilling costs related to resource development drilling of the South-East Deeps zone.
⁴ By-product credits reflect realized metal prices of zinc, lead, gold and copper for the applicable period, which includes any final settlement adjustments from prior periods.
⁵ Payable silver equivalents utilize the average realized prices during the three months ended March 31, 2024, of $22.91/oz silver, $1.07/lb zinc, $0.85/lb lead, $1,939/oz gold and $3.87/lb copper. Payable silver equivalents utilize the average realized prices during the three months ended March 31, 2023, of $26.61/oz silver, $1.43/lb zinc, $1.05/lb lead and $1,787/oz gold. Realized prices include the impact of final settlement adjustments from sales.
