SEATTLE (Scrap Monster): Allied Gold Corporation has commenced operations at its Sadiola mine following the successful start-up of the fresh ore comminution circuit installed under the Phase 1 expansion, marking a key milestone in the asset’s long-term growth strategy. The Phase 1 expansion is designed to lift production, lower operating costs and significantly improve cash flow through a phased development approach.
With the new circuit now operational, Sadiola can increase the proportion of higher-grade fresh ore in its feed from about 20% to nearly 60%, at an expected throughput of 5.7 million tonnes per year. The first quarter of 2026 is expected to be the first full period benefiting from increased fresh ore contributions. Medium-term production levels will vary as mining advances toward higher-grade pushbacks.

Allied is also advancing engineering work for a pre-leach thickener and plant control system upgrades in 2026, supporting both operational efficiency and the planned Phase 2 expansion. Studies are nearing completion to define a more capital-efficient, modular Phase 2 development.
Following Phase 1 completion, Sadiola is expected to produce 200,000 to 230,000 ounces annually from 2026, up to 30% above 2023 levels. Fourth-quarter production is forecast at about 60,000 ounces, while total company output is expected to exceed 113,000 ounces. Allied has reaffirmed full-year guidance of over 375,000 gold ounces.
