First Majestic Reports Positive Exploration

Results at San Dimas

Vancouver, British Columbia--(Newsfile Corp. - June 13, 2024) - 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 exploration program at the San Dimas Silver/Gold Mine located in Durango State,

Mexico. The drill program was designed to test new silver and gold mineral targets, add Mineral

Resources, and convert Mineral Resources to Mineral Reserves.

"We are very pleased with the positive exploration results that we continue to achieve at San Dimas in

2024,"

stated Keith Neumeyer, President & CEO of First Majestic.

"The recent drilling has continued to

highlight San Dimas' 71,867 hectare prospectivity through the intersection of significant gold and

silver mineralization

.

Drilling to convert Inferred to Indicated Mineral Resources at Perez, Santa

Regina and Elia has, in multiple cases, returned better than expected results. Resource expansion

drilling has confirmed the Perez vein remains open to the east and west, the Sinaloa mineralized

system is open down-dip, and the Santa Teresa mineralization is open for approximately one

kilometre to the west."

SAN DIMAS EXPLORATION RESULTS

Exploration drilling at San Dimas intersected significant gold and silver mineralization in multiple veins

focused in the central and western regions of the property. Four areas are highlighted here: Perez,

Sinaloa-Elia, Santa Regina and Santa Teresa (see Figure 1 below).

Drilling for the Perez vein extended gold and silver mineralization up-dip on several ore shoots, further

defining a recently identified mineralized shoot to the east. Step-out drilling in the easternmost extension

of the vein confirmed vein continuity. The Perez vein exploration potential remains open both to the east

and west (see Figure 2). Select drill hole assay grades and true width intervals of the vein intersections

are highlighted below:

PE24_297: 7.36 g/t Au and 1,129 g/t Ag over 6.72 m;

PE24_309: 10.87 g/t Au and 1,034 g/t Ag over 7.88 m;

PE23_294: 1.99 g/t Au and 440 g/t Ag over 6.08 m;

PE24_289: 3.26 g/t Au and 381 gpt Ag over 2.79 m.

At the historic Sinaloa-Elia vein system located in the western portion of the property, drilling intersected

several intervals of gold and silver mineralized veins. Resource conversion drilling confirms and further

delineates mineralization below the historic Sinaloa vein with several intercepts returning better than

expected values. Expansionary drilling below historic mining at Elia intersected two significant vein

intercepts, highlighting down-dip potential (see Figure 3). Select drill hole assay grades and true width

intervals of the Sinaloa-Elia vein system intersections are highlighted below:

SIN24_092: 39.28 g/t Au and 1,905 g/t Ag over 1.76 m;

EL24_266: 20.41 g/t Au and 1,702 g/t Ag over 2.15 m;

EL24_265: 10.46 g/t Au and 879 g/t Ag over 0.92 m.

Resource conversion drilling at Santa Regina has returned significant intercepts while locally growing the

Inferred Mineral Resource (see Figure 4). Drill hole assay grades and true width intervals of the Santa

Regina vein intersections are highlighted below:

SRE23_287: 13.24 g/t Au and 1,501 g/t Ag over 0.94 m;

SRE23_282: 9.44 g/t Au and 1,069 g/t Ag over 1.34 m;

SRE23_293: 9.27 g/t Au also returned and 849 g/t Ag over 1.52 m.

Expansionary drilling of the Santa Teresa vein has returned significant intercepts in the eastern and

western extensions of the historic mine. Early results from the western extension drilling have confirmed

vein continuity and prospectivity in this direction where approximately 1 kilometre of strike length of

potential remains untested (see Figure 5). Drill hole assay grades and true width intervals of the Santa

Teresa vein intersections are highlighted below:

STA24_029: 4.86 g/t Au and 511 g/t Ag over 2.18 m;

STA23_028: 4.10 g/t Au and 79 g/t Ag over 2.09 m.

Notes:

1

.

All holes are Diamond Drill; AgEq grade = silver grade (g/t) + [gold grade (g/t)*80].

2

.

From and Length indicated in metres, true width of the intercept is calculated per drill hole and vein angles.

3

.

See Table A1 for details regarding drill hole locations, sample type, azimuth, dip and total depth.

Gold and silver drill hole intercepts were composited using the length weighted averages of uncapped

sample assays, a 190 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 but above 100 g/t AgEq 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.

First Majestic's drilling programs follow established QA/QC insertion protocols with standards, blanks

and duplicates introduced to the sample stream. 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 First Majestic's owned and operated Central Laboratory (ISO

9001:2015) or to SGS (ISO/IEC 17025:2017), and independent third-party laboratory.

At the Central Lab, gold is analyzed by fire assay with atomic absorption finish (Au-AA13), and by fire

assay gravimetric finish (ASAG-13-Au, ASAG-15-Au). Results above 10 g/t gold are analyzed by 30 g

fire assay gravimetric finish (ASAG-14). Silver is analyzed by 3-Acid digest atomic absorption finish

(AAG-13) or by 30 g fire assay gravimetric finish (ASAG-13-Ag). Results above 200 g/t silver are

analyzed by 30 g fire assay gravimetric finish (ASAG-14).

At SGS, gold is analyzed by 30 g fire assay atomic absorption finish (GE-FAA30V5). Results above 10

g/t gold are analyzed by 30 g fire assay gravimetric finish (GO-FAG30V). Silver is analyzed by 3-acid

digest atomic absorption finish (GE-AAS33E50). Results above 100 g/t silver are analyzed by fire assay

gravimetric finish (GO-FAG37V).

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,
