Vancouver, British Columbia–(Newsfile Corp. – February 7, 2024) – First Majestic Silver Corp. (NYSE: AG) (TSX: FR) (FSE: FMV) (the “Company” or “First Majestic”) is pleased to announce positive drilling results from its 2023 exploration programs at San Dimas, Santa Elena, and Jerritt Canyon. The drilling programs were designed to test new silver and gold mineral targets, increase Mineral Resources and convert Mineral Resources to Mineral Reserves.

“We are very encouraged with the exploration results that have been achieved throughout 2023,” stated Keith Neumeyer, President & CEO of First Majestic. “The recent drilling has accomplished multiple goals from highlighting new geologically prospective areas to expanding and further defining known silver and gold mineralization. These results provide the basis for First Majestic’s year-end update of Mineral Resource and Mineral Reserve estimates expected to be released at the end of March. At San Dimas, we have tested previously undrilled veins like the Peggy vein and have explored extensions of known mineralization such as the Perez, Santa Teresa and Rosario veins. At Santa Elena, infill drilling of the Ermitaño vein intersected mineralization that is in many cases better than expected while follow up drilling of the new Javelin target at Jerritt Canyon has identified what appears to be a new gold mineralized zone near underground infrastructure and continues to highlight the exploration potential of the asset. These results set us up well for an exciting start for 2024.”

Drilling at the historic Sinaloa North-Elia mines/veins cut multiple gold and silver mineralized vein intercepts. The drilling confirmed and further delineates the presence of mineralization below historic mining of the Sinaloa vein (Figure 2). Select drill hole assay grade and intervals (true width) of the Sinaloa vein intersections are shown below:

• Hole SIN23_073: 11.53 g/t Au & 758 g/t Ag over 2.97m;
• Hole SIN23_076: 9.86 g/t Au & 779 g/t Ag over 1.51m;
• Hole SIN23_069: 12.65 g/t Au & 578 g/t Ag over 0.95m;

Expansionary drilling on the projection of the historic Santa Teresa vein has returned significant intercepts. The vein remains undrilled to the west for ~500m along strike for exploration upside (Figure 3). Drill hole assay grade and intervals (true width) of the vein intersections are shown below:

• Hole ST23_014
  • 3.95 g/t Au & 270 g/t Ag over 1.86m;
  • 2.07 g/t Au & 130 g/t Ag over 2.90m;
  • 40.40 g/t Au & 2,092 g/t Ag over 0.91m;
• Hole ST23_022
  • 3.19 g/t Au & 274 g/t Ag over 0.78m;

Drilling at the Perez vein delineated and extended gold and silver mineralization up-dip on one of the known ore shoots and further defined a newly identified mineralized shoot to the east. In some cases, drilling cut unmodeled gold and silver mineralization in secondary veins, breccias and stockworks in the hanging and foot wall of the primary vein for higher ore tonnage. The Perez vein exploration potential remains open to the east where it projects into an area where post-mineral faulting is anticipated to decrease, providing confirmation of ore body continuity (Figure 4). Select drill hole assay grade and intervals (true width) of the vein intersections are shown below:

• Hole PE23_225: 3.78 g/t Au & 421 g/t Ag over 7.78m;
• Hole PE23_242: 7.36g/t Au & 1,238 g/t Ag over 2.41m;
• Hole PE23-229: 3.69 g/t Au & 509 g/t Ag over 4.42m;

Drilling at the Rosario vein continues to delineate a mineralized volume east of the historic mining area (Figure 5). Drill testing also cut multiple veins in the footwall of Rosario: the Macho Bayo, Peggy and Basilisa veins. The intersection of the Peggy vein returned significant gold and silver values over 3m, the newly discovered mineralization is open in all directions (Figure 6). Select drill hole assay grade and intervals (true width) are shown below:

• Hole RO23_031: 7.31g/t Au & 598 g/t Ag, 0.77 m;
• Hole RO23_032: 7.69 g/t Au & 8g/t Ag, 3.29 m (Peggy vein)

Drilling designed to expand the Javelin target identified in July 2023 cut multiple significant gold intersections located between 90m and 340m from existing Smith mine developments. The flat-lying geometry of the gold mineralization trends at a relatively low angle to the drill hole intersections which define a mineralized volume that remains open in multiple directions (Figure 9 and Figure 10).

• Hole SMI-230011:
  • 4.34 g/t Au over 6.1m;
  • 8.76 g/t Au over 15.2m;
• Hole SMI-230012:
  • 8.31 g/t Au over 5.2m;
• Hole SMI-230013:
  • 4.70 g/t Au over 9.1m;
  • 5.80 g/t Au over 12.9m;
  • 7.44 g/t Au over 15.7m;
  • 4.50 g/t Au over 7.0m;

Drilling of the Purple Haze exploration target intersected new gold mineralization located up to 100m away from existing developments of the SSX mine. The geometry and controls of the gold mineralization are interpreted to trend at a relatively low angle to the drill hole intersections as shown in Figure 11 and Figure 12. Mineralization remains open in multiple directions.

• Hole SSX-230010:
  • 6.13 g/t Au over 5.3m;
• Hole SSX-230011:
  • 4.33 g/t Au over 19.8m;
  • 3.47 g/t Au over 11.2m;
  • 4.60 g/t Au over 16.8m;
• Hole SSX-230013:
  • 8.97 g/t Au over 6.1m;

Exploration drilling designed to test prospective geologic features in the Gridiron target cut two significant gold intercepts located approximately 80 and 120m away from existing SSX mine development. The mineralization is hosted adjacent to a Jurassic dike cutting the base of the Silurian Roberts Mountain Formation. The geometry of the gold mineralization is not yet defined, and the mineralization is open in several directions (Figure 13 and Figure 14).

• Hole SSX-235020:
  • 4.1m g/t Au over 6.1m;
  • 12.04 g/t Au over 25.9m;

Table 1: Summary of Significant Silver and Gold Drill Hole Intercepts at San Dimas.

Note: All holes are Diamond Drill; AgEq grade = silver grade (g/t) + [gold grade (g/t)*80]
From, To and Length indicated in metres, true width of the intercept is calculated per drill hole and vein angles.

Gold and silver drill hole intercepts at San Dimas were composited using the length weighted averages of uncapped sample assays, a 190 g/t AgEq minimum grade, and a minimum composite length of 0.7m (true width). A maximum 1m 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 drillhole and vein angle geometry.
