**NEWS RELEASE**

New York - AG September 3, 2025 <br> Toronto - AG <br> Frankfurt - FMV

<u>**First Majestic Reports Positive Exploration Results at Los Gatos**</u>

*Expansionary Drilling at Los Gatos Intersects Significant Silver and Base Metal Mineralization*

Vancouver, BC, Canada - First Majestic Silver Corp. (NYSE:AG) (TSX:AG) (FSE:FMV) (the "Company" or "First Majestic") is pleased to announce positive drilling results from its 2024/2025 exploration programs at the Los Gatos Silver Mine in Chihuahua, Mexico. The drilling programs were designed to expand silver, zinc, lead, copper and gold mineralization in the South-East Deeps, Central Deeps and North-West Deeps zones. None of the reported drill results were included in the Company's year-end Mineral Reserve and Mineral Resource Estimates.

*"Following the acquisition of Gatos Silver, the exploration program has advanced smoothly alongside all other aspects of the operation,"* stated Keith Neumeyer, President & CEO of First Majestic. *"A major driver for acquiring Los Gatos was the district's significant exploration upside, and the latest drilling results reinforce that potential. Ongoing drilling continues to expand mineralization across multiple zones, supporting our expectation for meaningful Mineral Resource growth at Los Gatos."*

**KEY DRILLING HIGHLIGHTS:**

Ongoing exploration drilling intersected significant silver and base metals mineralization across all three zones tested: South-East Deeps, Central Deeps and North-West Deeps. A selection of significant drill hole intercepts from these zones (Figure 1) are highlighted in Tables 1 and 2 below:

**EXPLORATION RESULTS** 

Exploration drilling designed to expand near-mine mineralization intersected significant silver and base metal mineralization while targeting the extension of the South-East Deeps orebody, along with exploration of the recently identified Central and North-West Deeps mineralization zones. Results from the program are summarized below (Figure 2).

**South-East Deeps Zone**

Exploration drilling of the South-East Deeps zone extended silver and base metals mineralization along plunge in the southeast portion of the vein system (Figure 3). The drilling continues to target an Inferred drill spacing, as the extensions of the system are tested. Results of the drilling program confirm the continuity of the South-East Deeps, as the known limits to the mineralization are extended. Future drilling will target the down-plunge potential at a wider spacing to test the geological limits of the system. Infill and Resource conversion drilling will be executed from the underground mine, once ramp and level access is established. Select significant drill hole intervals are shown below in Figure 4.

**Central and North-West Deeps Zones**

Drilling at the exploration targets in the Central and North-West Deeps zones confirmed the presence of silver and base metals mineralization at depth and identified a faulted offset from the main Los Gatos deposit (See Figure 5). Ongoing drilling is testing the lithological-structural model in these zones, to determine accurate mineralization controls. Drilling was conducted at a widely spaced exploration stage, targeting areas of interest, and will tighten to Inferred drill hole spacing throughout the remainder of 2025. All drilling has intersected the geological target as projected, with grade variability controlled by geological criteria.

------

The significant intervals returned from this drill program continue to grow and refine the areas of interest, with recent results indicating that the system remains open along strike to the northwest. Select significant drill hole intervals are shown in cross sections below in Figure 5.

<u>Notes:</u> 

* All holes are Diamond Drill Core; AgEq grade = Ag grade (g/t) + [Au grade (g/t) \* 20.5] + [Zn grade (%) \* 21.9] + [Pb grade (%) \* 27.3 to 28.0] + [Cu grade (%) \* 0 to 112.6)
 
Note - AgEq grade formula considers process plant recoveries and concentrate payable and deductible terms. Recovery, Payable and Deductible terms are variable by concentrate product. For further details, see the Company's most recently filed AIF available under the Company's SEDAR+ profile at <u>www.sedarplus.ca</u>.
Process Plant recoveries range from:
 
Ag = 88.2%, Au = 54.2%, Zn = 63.4%, Pb = 87.2% - 89.4%, Cu = 0 to 82.0% (Pb and Cu recoveries vary depending on Pb to Cu ratios. See the Company's most recently filed AIF.)

Payable terms range from:
 
Ag = 95%, Au = 39%, Zn = 85%, Pb = 95%, Cu = 0 to 97% (Cu payable terms vary depending on concentrate. See the Company's most recently filed AIF)

* "From" and "To" lengths indicated in metres, true width of the intercept is calculated per drill hole and vein angles.

* See Appendix to this news release for details regarding drill hole locations, sample type, azimuth, dip and total depth.

* Where present, single samples or intercepts with assay results higher than 500 g/t AgEq are highlighted as "Include" in each intercept.

At Los Gatos, silver, zinc, lead, gold and copper drill hole intercepts were composited using the length weighted averages of uncapped sample assays, a 140 g/t AgEq minimum grade, and a minimum composite length of 0.7 m (true width). A maximum one metre below the minimum grade was allowed as internal dilution and a single sample below the minimum AgEq grade was allowed in the hanging or footwall to achieve minimum true width in select cases. True width of intercepts is calculated based on current understanding of drill hole and vein angle geometry. All individual samples or intercepts higher than 500 g/t AgEq are reported as "include".

First Majestic's Los Gatos drilling programs follow established Quality Assurance / Quality Control ("QA/QC") insertion protocols with standards, blanks and duplicates introduced to the sample stream and submission of check duplicates to an independent third-party laboratory. After geological logging, all drill core samples are cut in half. One half of the core is submitted to the laboratory for analysis, and the remaining half is retained on-site for verification and reference purposes.

Core samples were submitted to the ALS preparation facilities in Chihuahua City, Mexico for pulp preparation and subsequently to the ALS laboratory in Vancouver, British Columbia, Canada for analysis (ISO/IEC 17025:2017). At ALS, silver, zinc, lead and copper are analyzed by 4-acid digestion with Inductively Coupled Plasma Atomic Emission Spectrometry finish (ME-ICP61). Samples with overlimit results are analyzed using ore grade 4-acid digestion and ICP finish analysis (OG62). Gold is analyzed by 30 g fire assay atomic absorption finish (Au-AA23).

For further information concerning QA/QC and data verification matters, key assumptions, parameters, and methods used by the Company to estimate Mineral Reserves and Mineral Resources, and for a detailed description of known legal, political, environmental, and other risks that could materially affect the Company's business and the potential development of Mineral Reserves and Mineral Resources, see the Company's most recently filed Annual Information Form available under the Company's SEDAR+ profile at <u>www.sedarplus.ca</u> and the Company's Annual Report on Form 40-F for the year ended December 31, 2024 filed with the United States Securities and Exchange Commission on EDGAR at <u>www.sec.gov/edgar</u>.

**Cautionary Note Regarding Forward-Looking Statements**

This news release contains "forward-looking information" and "forward-looking statements" under applicable Canadian and U.S. securities laws (collectively, "forward-looking statements"). These statements relate to future events or the Company's future performance, business prospects or opportunities that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management made in light of management's experience and perception of historical trends. Assumptions may prove to be incorrect and actual results and future events may differ materially from those anticipated. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives or future events or performance (often, but not always, using words or phrases such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", "forecast", "potential", "target", "intend", "could", "might", "should", "believe" and similar expressions) are not statements of historical fact and may be "forward-looking statements".

Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause actual results to materially differ from those expressed or implied by such forward-looking statements, including but not limited to: material adverse changes, unexpected changes in laws, rules or regulations, or their enforcement by applicable authorities; the failure of parties to contracts with the company to perform as agreed; social or labour unrest; changes in commodity prices; and the failure of exploration programs or studies to deliver anticipated results or results that would justify and support continued exploration, studies, development or operations. Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended.

------

The Company believes that the expectations reflected in these forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included herein should not be unduly relied upon.
