How Will the Overhaul Impact Energy Supply and Cost at Sadiola?

How Will the Mine's Power Demand Be Met Across Expansion Phases?

As Sadiola expands its operations, power demand will increase significantly. Allied Gold has developed a comprehensive plan to meet these growing energy requirements through a scalable approach.

Phase 1 Energy Demand requires approximately 20 MW to support the initial expansion. This represents the baseline power needed to drive the increased processing capacity at the mine.

Phase 2 Projection anticipates an increase to approximately 32 MW as operations continue to scale. This 60% increase in power demand necessitates a robust and flexible energy solution that can grow with the operation.

The Renewable Integration component involves an initial solar plant designed to supply peak capacity of approximately 35 MW, which will cover roughly 40% of Phase 1 energy demand. This significant renewable component represents a major step toward electrification & decarbonisation in mining operations.

A Battery Storage system of 30 MWh will be paired with the solar installation during the early rollout. This storage capacity is crucial for managing demand peaks and ensuring power availability during non-sunlight hours. The system is designed to be expandable to 45 MWh in later phases.

The Potential Renewable Growth plan could eventually see up to 60 MW of solar capacity and 45 MWh of battery storage in future development stages. This expanded renewable footprint would further reduce operational costs and environmental impact.

What Cost and Efficiency Gains Are Expected?

The financial benefits of this energy transformation are projected to be substantial, with staged improvements delivering increasingly significant savings:

These cost reductions are particularly significant in the context of gold mining economics, where energy typically represents 15-20% of all-in sustaining costs. The projected savings of $150-$200 per ounce could potentially transform Sadiola's profitability profile, especially in a competitive gold market.

A particularly innovative aspect of the implementation is the deferred payment structure for equipment, which minimizes upfront capital expenditure and strengthens Allied Gold's financial flexibility. This approach allows the company to begin realizing operational savings before the bulk of capital payments come due.

Industry observers note that this financial structure is increasingly common in mining industry innovation, as it aligns the interests of equipment suppliers with the mining company's success. Equipment providers have greater confidence in the reliability and performance of their systems, while mining companies can manage cash flow more effectively.

Key Insight:
The investments at Sadiola will ensure robust power for current and future mining needs while systematically cutting costs, fossil fuel dependence, and carbon emissions. The carefully staged implementation minimizes financial risk while maximizing operational benefits.
