Rhea-AI Filing Summary
Alamos Gold Inc. reports strong exploration results across its Mulatos District in Mexico, reinforcing the growth potential of its Puerto Del Aire (PDA) sulphide project and nearby targets. In 2025, the company spent $20 million on Mulatos exploration, completing 56,117 metres of drilling in 170 holes.
At Cerro Pelon, step-out drilling below the previously mined oxide pit continues to intersect wide, high-grade zones such as 5.60 g/t Au over 23.85 metres and 6.58 g/t Au over 15.15 metres, supporting further growth in higher-grade Mineral Resources. Cerro Pelon lies nine kilometres by road from the planned PDA mill and already hosts a 104,000 ounce Measured and Indicated Mineral Resource grading 4.49 g/t Au.
At PDA, drilling continues to extend mineralization beyond existing Mineral Reserves, which increased 9% at year-end 2024 to 1.1 million ounces grading 5.45 g/t Au. Highlights include 13.64 g/t Au over 8.97 metres and 43.70 g/t Au (cut to 40.00 g/t Au) over 0.81 metres. A new discovery at the Halcon target returned broad sulphide-hosted intercepts such as 3.04 g/t Au over 47.60 metres and 3.53 g/t Au over 37.35 metres. Construction of the PDA project, including a new mill to process higher-grade sulphides, is ramping up with initial production anticipated mid-2027.

Insights
Exploration results strengthen Mulatos sulphide pipeline but impact depends on future resource updates.
Alamos Gold is highlighting continued exploration success around its Mulatos District, centred on the higher-grade PDA underground project. The company reports a $20 million Mulatos exploration spend in 2025 and multiple high-grade intercepts at PDA, Cerro Pelon and the new Halcon target. Existing Mineral Reserves at PDA stood at 1.1 million ounces grading 5.45 g/t Au after a 9% increase at year-end 2024, while Cerro Pelon hosts 104,000 ounces at 4.49 g/t Au.
The key operational angle is that PDA will include a new mill designed for higher-grade sulphide ore, with initial production anticipated mid-2027. Nearby sulphide sources such as Cerro Pelon and Halcon, located within trucking distance of the planned mill, are being evaluated as additional mill feed. Intervals like 5.60 g/t Au over 23.85 metres at Cerro Pelon and 3.04 g/t Au over 47.60 metres at Halcon suggest meaningful mineralized volumes, though they remain at the drilling stage.
From an investment perspective, these results reinforce the longer-term growth story at Mulatos but do not yet change project economics, which were previously described as low-cost and high-return based on an internal study. The next important milestones will be updated Mineral Resource and Reserve statements and progress on PDA construction toward the targeted mid-2027 first production, which will clarify how much of this exploration success converts into mineable ounces.

Alamos Gold Extends High-Grade Mineralization Across Multiple Targets within Mulatos District Including PDA, Cerro Pelon, and New Discovery at Halcon
Toronto, Ontario (January 21, 2026) – Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported new results from ongoing surface exploration drilling within the Mulatos District. Drilling continues to extend high-grade gold mineralization beyond Mineral Reserves at Puerto Del Aire (“PDA”), and Mineral Resources at Cerro Pelon. Additionally, drilling within a new area of focus at Halcon has intersected wide intervals of significant sulphide-hosted gold mineralization.
Cerro Pelon, Halcon and other targets across the District including La Yaqui Grande, represent upside to the PDA project as potential sources of additional higher-grade sulphide ore. The PDA project will include the construction of a mill to process higher-grade sulphide ore from PDA, opening up new opportunities to define and incorporate additional sulphide ore from across the District. PDA remains on track for initial production mid-2027.
“Over the past several years, our focus within the Mulatos District has shifted to targeting higher grade sulphide mineralization. Our long-term track record of exploration success has continued having defined more than a million ounces of Mineral Reserves at PDA, and an initial Mineral Resource at Cerro Pelon. Ongoing success over the past year is expected to drive further Resource growth at Cerro Pelon, and resulted in a new discovery at Halcon, highlighting both the significant upside opportunities to the PDA project, and tremendous exploration potential across the Mulatos District,” said John A. McCluskey, President and Chief Executive Officer.
Cerro Pelon: step-out drilling below and north of the previously mined oxide deposit continues to intersect significant high-grade mineralization, extending and defining new structurally controlled feeder structures. This is expected to drive further growth in higher-grade Mineral Resources. Cerro Pelon is located nine kilometres (“km”) by road from the planned PDA mill and represents a potential source of additional high-grade mill feed. New highlights include1:
•5.60 g/t Au over 23.85 m (25PEL107);
•5.85 g/t Au over 17.35 m (5.93 m true width) (24PEL081);
•6.58 g/t Au over 15.15 m (25PEL127);
•6.64 g/t Au over 12.05 m (8.67 m true width) (25PEL109);
•4.28 g/t Au over 14.10 m (25PEL120);
•4.08 g/t Au over 13.70 m (25PEL157);
•12.95 g/t Au over 4.25 m (25PEL142);
•6.13 g/t Au over 7.20 m (25PEL156); and
•6.49 g/t Au over 6.05 m (2.75 m true width) (25PEL108).

2025 Exploration Program – Mulatos District
A total of $20 million was spent on exploration in the Mulatos District in 2025, similar to spending in 2024. The near-mine and regional drilling program totalled 56,117 m in 170 holes. This included 13,779 m of surface exploration drilling in 58 holes at the GAP-Victor and PDA targets at PDA, and 21,394 m in 56 holes at Cerro Pelon. Regional exploration drilling totalled 20,944 m in 56 holes focused on advanced and greenfield targets within the Mulatos District. The Halcon discovery was made as part of the regional exploration drilling program where scout drilling tested a new geological interpretation of the area.
PDA is a higher-grade underground deposit located adjacent to the main Mulatos pit (Figure 1). The results of a positive internal economic study were announced in September 2024 and highlighted an attractive, low-cost, high-return project. With the amendment to the environmental permit received in 2025, construction activities have been ramping up with first production anticipated mid-2027.
The planned addition of a mill to process higher-grade sulphides has created new opportunities for growth within the Mulatos District. This includes Cerro Pelon, where drilling in 2024 was successful in defining an initial Measured and Indicated Mineral Resource at Cerro Pelon totaling 104,000 ounces, grading 4.49 g/t Au. Cerro Pelon remains open in multiple directions and represents upside to the PDA project, with the deposit within trucking distance of the planned mill.
Cerro Pelon
The 2025 drill program at Cerro Pelon was focused on continuing to define and expand high-grade mineralization below and to the north of the previously mined open pit where wide, high-grade mineralization was intersected across multiple drill holes between 2008 to 2017.
High-grade gold and silver mineralization is localized along and at the intersection of north north-west structures, and east north-east structures, thought to represent high sulphidation feeder zones (Figure 2 and 3). Ongoing drilling is expected to refine the structurally controlled zones. There is significant potential to expand the mineralization in all directions as demonstrated by the results from the most northerly two areas of the deposit. A total of 21,394 m of drilling was completed in 2025. New highlights from this drilling include1:
•5.60 g/t Au over 23.85 m (25PEL107);
•5.85 g/t Au over 17.35 m (5.93 m true width) (24PEL081);
•6.58 g/t Au over 15.15 m (25PEL127);
•6.64 g/t Au over 12.05 m (8.67 m true width) (25PEL109);
•4.28 g/t Au over 14.10 m (25PEL120);
•4.08 g/t Au over 13.70 m (25PEL157);
•12.95 g/t Au over 4.25 m (25PEL142);
•6.13 g/t Au over 7.20 m (25PEL156); and
•6.49 g/t Au over 6.05 m (2.75 m true width) (25PEL108).

PDA
PDA is a higher-grade underground deposit located adjacent to the main Mulatos pit and is comprised of multiple mineralized zones including PDA, Gap, Victor, and Estrella (Figure 4). The focus of the 2025 surface exploration program was building upon the successful growth of the deposit over the last several years, including a 9% increase in the year end 2024 Mineral Reserves to 1.1 million ounces, grading 5.45 g/t Au.
In 2025, 2,988 m of drilling was completed within the GAP-Victor zones, and in the relatively untested area between the PDA zones and GAP-Victor. Another 9,618 m of drilling was completed at PDA with the goal of Mineral Resource expansion. Drilling continues to extend high-grade mineralization beyond existing Mineral Reserves; however, limited drilling was completed in 2025 with the focus shifting to construction of the project.
Exploration and Mineral Resource Expansion drilling will recommence at PDA once underground drill platforms have been established to allow for more efficient exploration drill testing below unmineralized cover rock. With the deposit open in multiple directions, there is excellent potential for PDA to continue to grow. Over the past four years, discovery costs at PDA have averaged $19 per ounce.
New highlights from results received since the year end 2024 Mineral Reserves and Resources include2:
•13.64 g/t Au over 8.97 m (24MUL397);
•3.72 g/t Au over 15.60 m (24MUL398);
•4.27 g/t Au over 15.61 m (25MUL422);
•4.85 g/t Au over 14.92 m (24MUL403);
•8.79 g/t Au (6.90 g/t Au cut) over 6.92 m (25MUL411);
•5.77 g/t Au over 7.10 m (25MUL418);
•15.00 g/t Au over 2.91 m (24MUL395); and
•43.70 g/t Au (40.00 g/t Au cut) over 0.81 m (24MUL397).
2Composite widths for PDA are estimated true width of the mineralized zones. Drillhole composite gold grades reported as “cut” at PDA include higher grade samples which have been cut to 40 g/t Au.
Halcon Target
Drilling commenced in the eastern portion of the Halcon target area early in 2025 as part of the regional scout drilling program (Figure 5). Drilling initially tested a new geological interpretation in an area that had only tested near-surface gold mineralization associated with oxides. As exploration drilling advanced, wide intervals of significant sulphide-hosted gold mineralization were intersected within a new area of focus at Halcon. The mineralized hydrothermal breccia is currently interpreted to dip to the northeast, and gold intercepts range from 38 m below surface in the west, to 282 m below surface down dip to the northeast. Mineralization remains open to the north, south and down dip.
The Halcon target is located 2 km north of the La Yaqui Grande open pit and 7 km by road from the main Mulatos area. This new discovery is being targeted and evaluated as a potential additional source of sulphide mineralization to be processed within the PDA mill. New highlights include3:

Note to U.S. Investors – Mineral Reserve and Resource Estimates
Unless otherwise indicated, all Mineral Resource and Mineral Reserve estimates included in this news release have been prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Mining disclosure in the United States was previously required to comply with SEC Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Exchange Act of 1934, as amended. The U.S. Securities and Exchange Commission (the “SEC”) has adopted final rules, to replace SEC Industry Guide 7 with new mining disclosure rules under sub-part 1300 of Regulation S-K of the U.S. Securities Act (“Regulation S-K 1300”) which became mandatory for U.S. reporting companies beginning with the first fiscal year commencing on or after January 1, 2021. Under Regulation S-K 1300, the SEC now recognizes estimates of “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”. In addition, the SEC has amended its definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” to be substantially similar to international standards.
Investors are cautioned that while the above terms are “substantially similar” to CIM Definitions, there are differences in the definitions under Regulation S-K 1300 and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the mineral reserve or mineral resource estimates under the standards adopted under Regulation S-K 1300. U.S. investors are also cautioned that while the SEC recognizes “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under Regulation S-K 1300, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater degree of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable.

FAQ
What did Alamos Gold (AGI) announce about exploration at the Mulatos District?
Alamos Gold reported new surface exploration drilling results across the Mulatos District, including PDA, Cerro Pelon and a new discovery at the Halcon target. The drilling extends high-grade gold mineralization beyond existing Mineral Reserves at PDA and Mineral Resources at Cerro Pelon, and has defined wide intervals of sulphide-hosted mineralization at Halcon.
How much did Alamos Gold (AGI) spend on Mulatos exploration in 2025?
The company spent $20 million on exploration in the Mulatos District in 2025, similar to its 2024 spending. This funded 56,117 metres of drilling in 170 holes across near-mine and regional targets, including PDA, Cerro Pelon and Halcon.
What are the key drilling highlights at PDA and Cerro Pelon for Alamos Gold (AGI)?
At PDA, new intercepts include 13.64 g/t Au over 8.97 metres and 43.70 g/t Au (cut to 40.00 g/t Au) over 0.81 metres. At Cerro Pelon, highlights include 5.60 g/t Au over 23.85 metres and 6.58 g/t Au over 15.15 metres, supporting expectations for further growth in higher-grade Mineral Resources.
What is the significance of the Halcon discovery for Alamos Gold (AGI)?
The Halcon target, about 2 km north of the La Yaqui Grande open pit and 7 km by road from the main Mulatos area, has yielded wide sulphide-hosted gold intervals such as 3.04 g/t Au over 47.60 metres and 3.53 g/t Au over 37.35 metres. Alamos is evaluating Halcon as a potential additional source of higher-grade sulphide mill feed for the planned PDA mill.
When is Alamos Gold (AGI) expecting initial production from the PDA project?
The PDA project, a higher-grade underground deposit adjacent to the main Mulatos pit, is advancing into construction following an environmental permit amendment received in 2025. Alamos states that PDA remains on track for initial production in mid-2027.
What existing Mineral Reserves and Resources support Alamos Gold’s (AGI) PDA and Cerro Pelon projects?
At year-end 2024, PDA’s Mineral Reserves increased by 9% to 1.1 million ounces of gold grading 5.45 g/t Au. At Cerro Pelon, drilling in 2024 defined an initial Measured and Indicated Mineral Resource totaling 104,000 ounces grading 4.49 g/t Au, with the deposit remaining open in multiple directions.
