Alamos Gold Inc. released a detailed Expansion Study for its Island Gold District in Ontario, outlining a major scale-up of operations. The plan enlarges Proven and Probable Mineral Reserves by 30% to 8.3 million ounces of gold and expands the Magino mill to 20,000 tonnes per day, blending 3,000 tpd of high-grade underground ore with 17,000 tpd from the open pit.
Average annual production is expected to reach 534,000 ounces over 10 years from 2028, and 490,000 ounces over 15 years, with mine-site all-in sustaining costs projected at about $1,025 per ounce over the first 10 years post expansion. Growth capital for the IGD Expansion is estimated at $542 million, within a total life-of-mine capital spend of $3.0 billion, or $393 per ounce sold.
On the economic side, the study estimates an after-tax NPV (5%) of $8.2 billion at a long-term gold price of $3,200 per ounce and a 53% after-tax IRR, rising to a $12.2 billion after-tax NPV (5%) and 69% IRR at $4,500 per ounce. The company also highlights a 56% reduction in greenhouse gas emissions per ounce from already below-industry levels and expects the district to self-finance all growth capital while generating increasing free cash flow after 2028.
Alamos Gold Inc. reported strong 2025 exploration and delineation drilling results at its Island Gold District in Ontario, highlighting continued growth of high-grade gold zones and regional targets.
At the past-producing Cline-Pick mines, one hole intersected 178.07 g/t gold over 3.54 metres, with multiple sub‑intervals exceeding 200 g/t, described as one of the best holes drilled there. Underground and surface drilling at the Island Gold Mine extended high-grade mineralization in the main C- and E1E-zones, as well as new hanging wall and footwall structures such as the NS2, NS3, NS4 and NTH4 zones, with numerous intercepts above 10 g/t gold over several metres.
The company spent $24 million on Island Gold District exploration in 2025, completing extensive underground, surface, and regional drilling aimed at converting Mineral Resources to Mineral Reserves and supporting an Island Gold District Expansion Study and a potential larger Magino mill expansion with additional higher-grade feed from Cline-Pick and Edwards.
Alamos Gold Inc. reported new underground exploration results from its Young-Davidson mine, highlighting higher-grade gold mineralization in multiple hanging wall zones near existing infrastructure and within the main Young-Davidson syenite.
Key intercepts from the South Syenite Zone include 16.36 g/t Au (cut to 6.65 g/t) over 17.90 m and 9.15 g/t Au (cut to 5.56 g/t) over 22.00 m. Mid-mine hanging wall drilling returned intervals such as 10.12 g/t Au (cut to 3.27 g/t) over 17.30 m and 12.09 g/t Au (cut to 5.40 g/t) over 7.00 m. Expansion drilling in the Young-Davidson syenite also intersected 4.50 g/t Au (cut to 4.03 g/t) over 15.65 m and 7.45 g/t Au (cut to 4.35 g/t) over 8.50 m.
In 2025, exploration spending at Young-Davidson totaled $13.1 million, covering 34,080 m of drilling across 81 holes plus 448 m of underground exploration development. Many holes were completed after the year-end 2025 Mineral Reserve and Resource cut-off, so results mainly represent upside exploration potential rather than current reserves.
Alamos Gold reports strong 2025 exploration results at its Lynn Lake project in Manitoba and the Qiqavik gold project in Nunavik, Quebec, supporting its long-term organic growth strategy.
At Lynn Lake, $3.4 million was spent on 7,268 metres of drilling focused on the Linkwood and Burnt Timber satellite deposits. Drilling extended gold mineralization beyond the Mineral Reserves used in a 2025 internal study, with high-grade intercepts such as 21.70 g/t Au over 5.25 m at Linkwood and 27.68 g/t Au over 6.26 m at the nearby East Foster target. These results are expected to contribute to further Mineral Reserve and Mineral Resource growth and to extend mine life and production rates for the Lynn Lake project.
At Qiqavik, Alamos completed 8,736 metres of drilling in 29 holes across five target areas, with 72% of holes returning gold grades above 1.0 g/t Au. Standout results include 54.44 g/t Au over 2.10 m at the Avinngaq target and 36.10 g/t Au over 0.65 m at the Focused target, confirming multiple bedrock sources for previously identified high-grade boulder trends and reinforcing the district-scale potential of this early-stage project.
Alamos Gold Inc. announced that it will host a 2026 Investor Day in Toronto on February 4, 2026. Senior management plans to provide detailed presentations on the Island Gold District Expansion Study and an updated three-year guidance, along with a longer-term outlook.
The event will also cover development project updates and a global exploration update, giving investors more insight into the Company’s operating and growth plans. A live webcast of the presentation will begin at 8:30 am ET, with advance registration available at www.alamos2026investorday.com and an on-demand replay and archive accessible through the Company’s website.
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.
Alamos Gold Inc. announced that it plans to release its fourth quarter and full-year 2025 financial results after market close on Wednesday, February 18, 2026. Company senior management will host a conference call on Thursday, February 19, 2026 at 10:00 am ET to discuss the results.
