GWANDA – Multi-listed gold producer Caledonia Mining Corporation Plc has reached a major sustainability milestone, reducing its reliance on diesel for power generation to just 2% of total electricity consumption in 2025. This is a significant drop from 8% in 2020, as the company aggressively moves to insulate its operations from fuel price volatility and supply chain disruptions.

Breaking the Diesel Dependency
Caledonia’s diesel consumption now accounts for less than 3% of total operating costs, with annual usage averaging approximately two million litres. To ensure operational continuity, the company has secured a strategic buffer of over one million litres of fuel, providing a safeguard against short-term market shocks.
This sharp reduction in dependency follows the successful commissioning of solar power capacity, which now meets approximately 20% of the total power requirements at Blanket Mine. The remaining energy is drawn from Zimbabwe’s national grid.
The $14.2 Million Power Backbone
The company’s most ambitious infrastructure investment to date is a US$14.2 million project to construct a 34-kilometre electricity line. This dedicated link will connect Blanket Mine directly to Zimbabwe’s 132 kV backbone.
Key benefits of the project include:
- Reduced Costs: Lowering the blended price of power received from the grid.
- Reliability: Significantly reducing the frequency of power outages that previously forced the use of expensive backup diesel generators.
- Production Boost: The improved reliability is expected to increase gold output by approximately 1,000 ounces per annum.
“The study for this project has been completed, and the Board has approved US$14.2 million for its execution. Work is expected to commence immediately, with completion slated for the second quarter of 2027,” Caledonia stated in its preliminary results.
Engineering for Efficiency
In tandem with the grid project, Caledonia has approved a US$2.2 million initiative to convert the winder at Blanket’s Central Shaft from alternating current (AC) to direct current (DC). Scheduled for late 2026, this technical upgrade is expected to deliver annual cost savings of roughly US$600,000.
Geopolitical Resilience
Despite ongoing tensions in the Middle East, Caledonia reports zero impact on its operations. Zimbabwe’s dual sourcing of fuel from both the Middle East and South Africa provides a diversified supply chain that shields the miner from regional instability. Furthermore, Caledonia continues to route its exported gold through South Africa, ensuring a steady and uninterrupted revenue stream.
By combining renewable energy, massive infrastructure investment, and strategic stockpiling, Caledonia is setting a high bar for operational resilience in the Southern African mining sector.
