Magino mill hits target, but older mines stumble

Alamos wants to grow from a mid-tier miner into about 1 million ounces of annual gold output by 2030.
The Island Gold District is the main engine, and the Magino mill successfully hit its 10,000 tonnes per day target in July 2026.
High gold prices are funding internal growth, debt reduction, and a recent 60% dividend increase.
Execution remains a problem, as Young-Davidson cut guidance after seismic events forced permanent cost increases.
Canadian operations face labor and contractor inflation, adding about $30 per ounce to ongoing costs.

01 Running thesis

A bigger miner, if the mines behave

The bull case is simple. Alamos has a funded path to become much larger without betting the balance sheet. Management points to about 1 million ounces of annual production by 2030. The plan leans on Island Gold, Magino, Young-Davidson, Mulatos, PDA, and later Lynn Lake. The Magino mill successfully reached its 10,000 tonnes per day target in July 2026, proving the core integration thesis is working.

Gold prices are doing a lot of heavy lifting. Strong free cash flow has allowed the company to pay for growth, reduce debt, eliminate legacy Argonaut hedges, and boost the dividend by 60%. With fewer hedges in place, Alamos captures more upside when gold rises.

The bear case centers on whether Alamos can run each mine cleanly. The company missed 2025 production guidance after severe winter weather and other Canadian issues. In Q2 2026, Young-Davidson suffered seismic events that cut guidance and structurally increased sustaining capital by $10 to $15 million a year. Furthermore, a new labor retention program is adding $30 per ounce to Canadian costs.

Finn's view is balanced. Growth and financial health look better than day-to-day performance. The next proof points are Island Gold underground rates reaching 2,000 tonnes per day by year-end 2026 and shaft commissioning in early 2027.

Jul 2026→Q2 2026 results were mixed. The Magino mill successfully hit its 10,000 tonnes per day target, but Young-Davidson cut guidance after seismic events required a permanent $10 to $15 million annual increase in ground support capital.

Apr 2026→Q1 2026 confirmed strong cash flow and more hedge eliminations. However, execution risk remained as Young-Davidson missed plan and Magino's target moved to Q3 2026.

Feb 2026▲Alamos reported record free cash flow, a 60% dividend increase, and a 32% reserve increase. The positive update was partly offset by a 2025 production miss tied to winter weather.

Oct 2025▼The company cut full-year production guidance after a Magino mill capacitor failure and an Island Gold seismic event. Lynn Lake also slipped to 2029 with expected capital inflation of 15%.

Jul 2025→Alamos shut down the legacy Island Gold mill and moved high-grade ore toward the Magino mill. Costs moved higher, with full-year all-in sustaining cost guidance raised 12%.

May 2025▼Q1 2025 showed early Magino bottlenecks from winter design issues in crushing and conveying. Costs were also high, with all-in sustaining costs of $1,805 per ounce.

Feb 2025▲PDA received its amended environmental permit, reducing a key Mexico overhang. Alamos also greenlit Lynn Lake for a then-planned H1 2028 start.

Nov 2024▲Magino integration looked on track, with Island Gold ore batch tests showing 97% recoveries. PDA also extended the Mulatos mine plan to at least 2035.

02 Business model

Gold ounces and shared infrastructure

Alamos makes money by mining gold, processing ore, and selling gold into the market. Its costs are mostly mine labor, energy, contractors, equipment, sustaining capital, and growth capital. When gold prices rise faster than costs, margins expand.

The core strategy is district consolidation. Alamos bought Argonaut, including Magino, so Island Gold and Magino could use one larger mill and tailings setup. That lowers unit costs over time, especially now that the Magino mill is hitting its throughput targets.

The model struggles when mines face technical problems or capital budgets rise. Throughput, mining rates, dilution, and project cost updates dictate how much cash actually makes it back to investors.

03 Product portfolio

Where the ounces come from

Growth engine

Island Gold District

This combines Island Gold and Magino in Canada. The Magino mill hit 10,000 tonnes per day in July 2026, and underground mining rates are improving toward 2,000 tonnes per day.

Cash cow

Young-Davidson

This Canadian mine is a vital cash source, but recent seismic events required a guidance cut and enhanced ground support spending.

Steady

Mulatos District

Mulatos is the Mexico district. It is currently facing longer leach cycles that are deferring some production into 2027.

Growth engine

Puerto Del Aire, or PDA

PDA is the next leg for Mulatos. Portals were collared in Q2 2026, and first production is targeted for mid-2027.

Option

Lynn Lake

Lynn Lake is a future Canadian growth project. Forest fires delayed initial production to 2029, and capital estimates are expected to rise 15% versus the feasibility study.

Option

Exploration portfolio

Exploration remains key. The 2025 program helped lift year-end mineral reserves by 32% to 16 million ounces, with major gains at the Island Gold District.

05 Risk factors

What could break the plan

Young-Davidson ground support costs

Medium impact · High odds

Young-Davidson suffered seismic events in the lower mine in Q2 2026. This required enhanced ground support for rehabilitation, which will permanently add $10 to $15 million a year to sustaining capital.

We watchUpdates on the lower mine extraction sequence and three-year guidance at year-end.

Canadian labor and contractor inflation

Medium impact · High odds

Canadian operations are facing stiff contractor cost pressures. Management implemented a midyear retention program that adds roughly $30 per ounce to costs.

We watchAll-in sustaining costs per ounce in Canada in upcoming quarters.

Island Gold ramp execution

High impact · Medium odds

With the Magino mill now hitting 10,000 tonnes per day, the focus shifts to feeding it. Island Gold underground mining rates reached 1,550 tonnes per day in Q2 2026 but need to hit 2,000 by year-end.

We watchIsland Gold underground mining rates and the Phase III+ shaft commissioning in early 2027.

Project inflation eats the upside

High impact · Medium odds

Growth is funded internally, but it is not free. Lynn Lake slipped to 2029 after forest fires, with expected capital estimates 15% above the feasibility study.

We watchUpdated capital estimates for Lynn Lake and the Island Gold District expansion.

Mexico deferred production

Medium impact · Medium odds

Execution at Mulatos is seeing longer leach cycles due to ore characteristics and pad height. While overall recoveries remain at 85%, ounces are being deferred into 2027.

We watchMulatos production rates and cash flow contributions over the next two quarters.

06 Quick answers

In one breath

Is Alamos Gold mainly a Canada miner?

Yes, most of the growth plan is in Canada, especially the Island Gold District and Lynn Lake. The company also operates the Mulatos District in Mexico, where PDA is meant to extend mine life.

Why does Magino matter so much for AGI?

Magino gives Alamos a larger mill near Island Gold. Because the mill is now running at its target rate, Island Gold and Magino can share infrastructure and lower costs over time.

What is the biggest near-term test for Alamos Gold?

The main tests are ramping Island Gold underground mining to 2,000 tonnes per day by year-end 2026 and stabilizing Young-Davidson after recent seismic events.

Does AGI pay a dividend?

Yes. Management announced a 60% dividend increase in February 2026, helped by high gold prices and strong free cash flow.
