First Majestic (AG) secures Santo Niño, Navidad permits and plans $12M 2026 underground development
Rhea-AI Filing Summary
First Majestic Silver Corp. reports strong 2026 exploration progress at the Santo Niño and Navidad vein systems within its Santa Elena Silver/Gold Mine in Sonora, Mexico. The company has received permits to construct the Santo Niño and Navidad portals and plans an additional $12 million investment in 2026 for underground access, portal construction, decline and ramp development.
At Santo Niño, 26,904 metres of drilling across 69 holes in 2026 have focused on converting Inferred Mineral Resources to Indicated, with significant silver and gold intercepts generally better than modeled and highlighting higher-grade mineralization in the western vein. At Navidad’s Winter vein, 7,704 metres across 10 holes have returned high-grade intercepts near the edge of current Inferred Mineral Resources, supporting its role as a potential early mining area. Mineralization at Santo Niño currently extends about 1,100 metres along strike and 425 metres down dip, while the Winter vein extends roughly 1,000 metres along strike and 350 metres down dip, with multiple high-grade AgEq intervals listed in detailed drill tables.
Positive
- None.
Negative
- None.
Insights
Exploration success and permits move Santo Niño and Navidad toward potential underground development, backed by a defined 2026 spend.
First Majestic outlines an integrated exploration and access strategy at the Santa Elena district. In 2026, 26,904 m of drilling at Santo Niño and 7,704 m at Navidad target conversion of Inferred Mineral Resources to Indicated, using length‑weighted AgEq composites and defined cut-off grades.
Construction permits for the Santo Niño and Navidad portals, plus a planned $12 million 2026 investment, support haul-road, portal, decline and ramp development. Higher-grade intervals, such as 2.49 m grading 359 g/t Ag, 23.59 g/t Au and 2,128 g/t AgEq at the Winter vein, appear in both resource-conversion and addition drilling.
These programs remain at a scoping and pre‑feasibility level, with the company explicitly noting increased uncertainty and technical risk because Santo Niño and Navidad lack a pre-feasibility study and current technical report support for initiating mining. Future technical work and updated resource classifications will be central to assessing eventual production potential.

Vancouver, BC, Canada - First Majestic Silver Corp. (NYSE:AG) (TSX:AG) (FSE:FMV) (the "Company" or "First Majestic") is pleased to announce positive infill drilling results from the Santo Niño and Navidad targets at its Santa Elena Silver/Gold Mine in Sonora, Mexico. The Company has also received the permits required to construct the Santo Niño and Navidad portals and plans to invest an additional $12 million in 2026 to advance underground access, portal construction, and development work intended to position Santo Niño for near-term mining.
"The continued advancement of Santo Niño and Navidad marks an important step in unlocking the next phase of growth at Santa Elena," stated Keith Neumeyer, CEO of First Majestic. "Infill drilling continues to return significant silver and gold intercepts at both targets. With construction permits now received for the Santo Niño and Navidad portals, and an additional $12 million investment planned in 2026, we are moving Santo Niño from discovery toward near-term mining readiness while continuing to advance Navidad, one of the most significant discoveries made at Santa Elena to date. Together, Santo Niño and Navidad are expected to become important contributors to the future mine plan and have the potential to materially extend Santa Elena's mine life."
2026 EXPLORATION HIGHLIGHTS
Santo Niño Vein System
To date, a total of 26,904 metres ("m") of drilling has been completed across 69 holes in 2026 at Santo Niño as part of the Company's ongoing resource-conversion and development-focused drilling program. Drilling at Santo Niño has focused primarily on infilling the current Inferred Mineral Resources to support potential conversion to Indicated Mineral Resources and to advance near-term mine planning. Results received to date include significant silver and gold intercepts that are overall better than modeled and confirm the presence of higher-grade mineralization in the western portion of the vein.
Navidad Vein System
To date, a total of 7,704 m of drilling has been completed across 10 holes at Navidad in 2026. Drilling has focused primarily on supporting potential conversion of Inferred Mineral Resources to Indicated Mineral Resources at the Winter vein which, based on its geometric configuration, is expected to play an important role early in the future mine schedule. Results received to date include high-grade silver and gold intercepts near the edge of the current Inferred Mineral Resource.

Drilling remains ongoing at the Santo Niño and Navidad targets. At Santo Niño, drilling is being completed as part of a planned program of approximately 45,000 m in 2026. At Navidad, drilling is being completed as part of a planned program of approximately 17,000 m in 2026. The drilling is intended to increase data density, improve understanding of the mineralized volume, grade continuity, and vein geometry, and support potential conversion of Inferred Mineral Resources to Indicated Mineral Resources. This work is expected to strengthen geological confidence and support the basis for underground access design, mine planning, production scheduling, and economic evaluation.
Significant silver and gold mineralization intersected within the Santo Niño vein currently extends approximately 1,100 m along strike and 425 m down dip and the mineralization averages approximately 4.0 m in thickness ranging from 1.0 m to 16.0 m (Figure 2). Mineralized secondary veins and breccias in the hanging wall and/or footwall of the principal vein have also been identified in several drill holes and remain under investigation.

Significant silver and gold mineralization intersected within the Winter vein currently extends approximately 1,000 m along strike and 350 m down dip, with true thickness ranging from 2.8 m to 4.4 m (Figure 3). The 2026 drilling continues to support evaluation of the Winter vein as a potentially important early mining area within the Navidad mineralized system.

ADVANCING UNDERGROUND ACCESS TO SANTO NIÑO AND NAVIDAD
The Company is advancing Santo Niño and Navidad from resource definition toward underground development, supported by recently received portal construction permits and an additional $12 million investment planned for 2026. This next phase of work is expected to establish dedicated underground access to both areas, support decline and ramp development, and position higher-grade mineralization from Santo Niño and Navidad to contribute to the future Santa Elena district production profile.
A recently completed scoping-level study identified dedicated underground access as the preferred approach to advance the Santo Niño and Navidad mineral resources. At Santo Niño, the preferred access concept includes a dedicated portal, the Santo Niño portal, and an approximately 450 m haul road connecting the portal area to the existing Ermitaño haul road.
The study also indicates that development of an additional portal, the Navidad portal, located approximately 300 m from the Santa Elena processing facilities, together with ramp development from the lower levels of Ermitaño to provide secondary egress and ventilation, is expected to provide an efficient route to Navidad mineralization and support future haulage of mineralized material from the Navidad area (Figure 4).
Preliminary mining and processing schedules for the Santa Elena district resources indicate that higher-grade mineralization from Santo Niño and Navidad has a positive impact on production profiles, displacing lower-grade mineralization from other deposits.
The additional 2026 funding is planned to support construction of the Santo Niño and Navidad portals, advance hydrogeological studies, construct the haul road linking the Santo Niño portal to the Ermitaño haul road, complete approximately 800 m of decline development at Santo Niño, and complete an additional 1,300 m of development in the Ermitaño-to-Navidad ramp and from the Navidad portal.

Permitting
The Company has received the permits required for construction of the Santo Niño and Navidad portals, representing a key regulatory milestone in advancing toward underground development activities for the two mineral resources. With these permits now in hand, the Company plans to commence portal construction and related infrastructure work in the second half of 2026.

Notes:
- All holes are Diamond Drill Core; AgEq grade = Ag grade (g/t) + [Au (g/t) * 75].
- From and To length indicated in metres, true width of the intercept is calculated per drill hole and vein angles.
- See Appendix for details regarding drill hole locations, sample type, azimuth, dip and total depth.
- Significant silver and gold drill hole intercepts were composited using the length weighted averages of uncapped sample assays, a 90 g/t AgEq minimum grade (Cut-off-Grade, "COG") for Santo Niño, and 110 g/t AgEq minimum grade for Navidad; minimum composite length of 1.0 m (true width). A maximum of 1.0 m below the minimum grade cut-off was allowed as internal dilution. Where necessary to achieve minimum length, a single sample below the COG but grading >70g/t AgEq was allowed to be composited for short intervals.
- Where present, single samples or intercepts with assay results higher than 1000 g/t Ag and/or 10 g/t Au are highlighted as "Include" in each intercept.
DATA VERIFICATION
First Majestic's drilling programs follow established Quality Assurance, Quality Control ("QA/QC") insertion protocols with standards, blanks, and duplicates introduced into 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 core is retained on-site for verification and reference purposes or for future metallurgical testing.
Core samples were submitted to the SGS laboratory (ISO/IEC 17025:2017) and to the First Majestic Central laboratory (Central laboratory) (ISO 9001:2015). At SGS, gold is analyzed by 50 g fire assay atomic absorption finish (GE-FAA50V5). Results above 10 g/t gold are analyzed by 50 g fire assay gravimetric finish (GO-FAG50V). Silver is analyzed by 3-acid digest atomic absorption finish (GE-AAS33E50). Results above 100 g/t silver are analyzed by 50 g fire assay gravimetric finish (GO-FAG57V). At Central laboratory, gold is analyzed by 30g fire assay atomic absorption finish (AU-AA13). Results above 10 g/t are analyzed by 30 g fire assay gravimetric finish (ASAG-14). Silver is analyzed by 3-acid digestion atomic absorption finish (AAG-13). Results above 100 g/t are analyzed by 30 g fire assay gravimetric finish (ASAG-14, ASAG-13).

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. Forward-looking statements in this news release include but are not limited to statements with respect to: the Company's plans to invest an additional $12 million in 2026 to advance underground access, portal construction, and development work to position Santo Niño for near-term mining; the Company's expectations regarding the impact of the Santo Niño and Navidad vein systems on the future mine plans at Santa Elena; and the Company's planned drilling programs for Santo Niño and Navidad for 2026 and the results of such programs. These statements are not based on a pre-feasibility level study of Mineral Reserves that demonstrate the economic and technical viability of Santo Niño and Navidad. There is increased uncertainty related to the economics of mining Santo Niño and Navidad and increased technical risks of failure associated with a decision to initiate production from these areas prior to completing a pre-feasibility level study. The statements made relating to initiating mining at Santo Niño and Navidad are not based on a current technical report. Assumptions may prove to be incorrect and actual results and future events may differ materially from those anticipated. As such, investors are cautioned not to place undue reliance upon forward-looking statements as there can be no assurance that the plans, assumptions, or expectations upon which they are placed will occur. 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". Statements concerning proven and probable mineral reserves and mineral resource estimates may also be deemed to constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered as and if the property is developed, and in the case of Measured and Indicated Mineral Resources or Proven and Probable Mineral Reserves, such statements reflect the conclusion based on certain assumptions that the mineral deposit can be economically exploited.
Actual results may vary from 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; general economic conditions including inflation risks; labour relations; relations with local communities; changes in national or local governments; exchange rate fluctuations; environmental risks; requirements for additional capital; outcomes of pending litigation; 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 as well as those factors discussed in the section entitled "Risk Factors" in the Company's most recent Annual Information Form for the year ended December 31, 2025 filed with the Canadian securities regulatory authorities under the Company's SEDAR+ profile at www.sedarplus.ca and in the Company's Annual Report on Form 40-F for the year ended December 31, 2025 filed with the United States Securities and Exchange Commission on EDGAR at www.sec.gov/edgar. 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. These statements speak only as of the date hereof. The Company does not intend, and does not assume any obligation, to update these forward-looking statements, except as required by applicable laws.
