B2Gold Secures Fuel Supply Across All Mines in 2026

Energy Volatility and the New Economics of Remote Gold Mining

Fuel has quietly become one of the most strategically sensitive inputs in modern gold mining. While how gold price moves miners dominates investor headlines, it is the unglamorous logistics of diesel procurement, storage infrastructure, and supply chain continuity that increasingly determine whether a multi-jurisdictional producer hits its cost targets or misses them. For mining companies operating in remote, politically complex, or seasonally constrained environments, fuel is not simply a commodity input. It is a production-critical resource that must be secured months, sometimes years, in advance.

This reality has forced mid-tier gold producers to rethink how they classify and manage energy risk. The question is no longer just how much fuel costs, but whether it will be available at all, and under what conditions. B2Gold, which operates four producing gold mines across Mali, Canada, the Philippines, and Namibia, has developed one of the more sophisticated responses to this challenge in the mid-tier sector. The company's confirmation that it B2Gold secures fuel supply for all mines heading into 2026 production represents the visible outcome of a layered strategy built over several years.

Why Fuel Economics Sit at the Heart of AISC Sensitivity

All-in sustaining cost, or AISC, is the metric by which gold producers are ultimately judged on operational efficiency. It incorporates cash operating costs, sustaining capital, royalties, and site-level general and administrative expenses. What this figure does not transparently reveal, however, is the extent to which diesel and heavy fuel oil (HFO) consumption drives its movement from quarter to quarter.

For open-pit operations, haul truck fleets, excavators, and ancillary equipment consume diesel at substantial rates. For remote operations lacking grid connections, diesel generators also power processing facilities, camp infrastructure, and ancillary systems. In environments where fuel must be transported over long distances, through logistically complex corridors, or within narrow seasonal windows, the landed cost per litre can be significantly higher than refinery gate pricing would suggest.

B2Gold's Q1 2026 results offer a concrete illustration of what effective fuel management looks like in practice:

All four mines exceeded their individual production expectations in Q1, contributing to consolidated output that outpaced guidance. The absence of fuel-related disruptions across each site was a direct enabler of this performance. For a producer targeting between 820,000 and 970,000 oz for the full year, operational continuity at every mine is non-negotiable.

A Four-Mine Fuel Security Framework Built for Jurisdictional Diversity

What distinguishes B2Gold's approach from a generic procurement strategy is its deliberate acknowledgment that no single fuel supply model can serve four operations simultaneously when those operations exist in such fundamentally different logistical contexts. The Goose mine in Nunavut operates under Arctic conditions where seasonal access windows are measured in weeks. The Fekola Complex in Mali contends with landlocked supply chains in a region with periodic political instability. Masbate, situated on an island in the Philippine archipelago, depends on maritime supply networks. Otjikoto in Namibia has recently undergone a structural transformation that altered its entire energy consumption profile.

Each site therefore requires its own purpose-built fuel security architecture:

The portfolio-wide result is that B2Gold secures fuel supply for all mines through mechanisms calibrated to each site's specific vulnerability, rather than relying on a centralised procurement model that may fail when any one of those vulnerabilities is tested.

The Arctic Logistics Puzzle: How Goose Mine Secures Fuel in Nunavut

The Goose mine presents perhaps the most operationally demanding fuel supply challenge in B2Gold's portfolio. Located in Nunavut, Canada, the operation sits in one of the most remote and climatically extreme mining jurisdictions in the world. Year-round road access is not feasible, and the mine's resupply depends on a narrow combination of summer Arctic sealifts and winter ice road delivery seasons. Missing either window carries serious production risk.

To eliminate in-year procurement risk entirely, B2Gold adopted a forward-purchasing model that locks in fuel supply well before either logistics window opens. During Q3 2025, the company secured the complete fuel volume required for 2026 operations and the first quarter of 2027, with delivery completed in April 2026. This approach means that Goose's fuel position is effectively decoupled from spot market conditions during the active production year.

The physical infrastructure supporting this model is substantial. Total diesel storage capacity at the Goose site now exceeds 80 million litres, providing a multi-year buffer against potential logistics disruptions. The 2024 sealift operation demonstrated the scale of this undertaking, delivering approximately 84 million litres of arctic-grade diesel via 10 vessels and one barge, with the operation completed by late September 2024.

Arctic-grade diesel differs from standard highway diesel in meaningful ways. It requires lower pour points, specific viscosity characteristics at sub-zero temperatures, and often includes cold-flow additives or biocide treatment to remain pumpable and stable during extended winter storage. These specifications increase procurement costs above standard diesel benchmarks and limit the number of suppliers capable of meeting them, making forward contracting even more strategically important than it would be for a temperate-climate operation.

The forward-purchase model also carries an important financial dimension. Committing to large volume purchases nine to twelve months before delivery requires meaningful balance sheet capacity. B2Gold's $479 million cash position and $386 million in quarterly operating cash flow as of Q1 2026 provide the liquidity foundation to execute this strategy without constraining capital allocation elsewhere.

Fekola's Hybrid Energy Architecture as a Structural Cost Hedge

The Fekola Complex in Mali faces a different category of fuel risk. The mine is landlocked, meaning all fuel must travel overland through supply corridors that are sensitive to both regional logistics infrastructure and political conditions. Rather than relying solely on physical stockpiling to absorb this risk, B2Gold has pursued a parallel strategy of structural fuel consumption reduction through renewable mining power.

Fekola's hybrid power plant combines heavy fuel oil generation, diesel backup capacity, and a 30 MWac solar photovoltaic facility that was commissioned in 2021. The strategic rationale for solar integration is not primarily an environmental one, though emissions benefits exist. It is fundamentally a cost and risk management decision: every kilowatt-hour generated from solar is a kilowatt-hour that does not require HFO or diesel to produce.

The long-term operational objective at Fekola is to eliminate thermal engine operation entirely during peak daylight generation hours, which would compress fuel consumption into the periods when solar output is unavailable. When combined with the approximately 20% expansion of Fekola's diesel storage capacity currently underway, the site gains both a longer supply buffer and a structurally lower requirement for that buffer to be replenished.

Key Elements of Fekola's Fuel Resilience Strategy

• Uninterrupted fuel supply maintained at normal operational levels throughout 2025 and Q1 2026
• Diesel storage capacity expansion of approximately 20% currently in progress
• 30 MWac solar facility providing daytime generation that displaces thermal fuel consumption
• Hybrid HFO, diesel, and solar architecture reduces total annual fuel procurement volumes
• Structural reduction in fuel dependency provides compounding benefit: lower procurement costs, lower logistics complexity, reduced hedging requirements

Otjikoto's Mining Transition and Its Effect on Diesel Exposure

One of the less-discussed dimensions of B2Gold's fuel cost management is the operational transformation underway at Otjikoto in Namibia. When a mine transitions from open-pit to underground extraction, its energy consumption profile changes fundamentally. Open-pit operations are dominated by mobile diesel equipment: haul trucks, front-end loaders, drilling rigs, and ancillary support vehicles that collectively consume fuel at high rates proportional to material movement.

Underground mining replaces much of this mobile diesel fleet with fixed electrical infrastructure: conveyor systems, ventilation fans, hoists, and electrically powered trackless equipment. This structural shift in energy consumption allows underground operations to draw the majority of their power from grid or fixed generation sources rather than on-site diesel combustion.

Otjikoto completed its transition to underground mining in Q4 2025 and now draws power primarily from Namibia's national electricity grid, significantly reducing its diesel consumption footprint. Furthermore, the mine also operates one of the sector's earlier hybrid HFO and solar autonomous power plants, providing additional renewable generation capacity that further reduces thermal fuel dependency. These mining decarbonisation benefits flow directly into the mine's contribution to B2Gold's consolidated AISC.

Lower diesel volumes mean lower procurement costs, reduced logistics overhead, and diminished exposure to fuel price volatility events that cannot be hedged through financial instruments alone.

Financial Hedging as a Complement to Physical Supply Security

Physical fuel security addresses the risk of supply interruption. Financial hedging addresses the separate risk of fuel price movements on volumes that remain exposed to market pricing. B2Gold employs both mechanisms in combination, treating them as complementary rather than interchangeable tools.

As of the Q1 2026 reporting period, the company had hedged approximately 36% of its remaining 2026 fuel requirements at or below budget prices. This hedge ratio reflects a deliberate balance: sufficient protection against meaningful cost overruns without forfeiting all exposure to potential fuel price declines. Consequently, monitoring crude oil price trends remains relevant to how the company calibrates its unhedged exposure throughout the year.

The relationship between physical and financial mitigation across B2Gold's portfolio can be summarised as follows:

A 36% financial hedge ratio on remaining fuel needs is a considered position rather than a passive one. It suggests that management views the physical and structural mitigations already in place as sufficient to absorb much of the supply risk, and that financial hedges are being deployed selectively rather than as a blanket protection mechanism. This approach preserves some benefit if fuel prices decline while limiting downside exposure if they spike.

Solar Hybridisation Across Three Mines: The Compounding Dividend

The renewable energy installations at Fekola, Masbate, and Otjikoto collectively represent a fuel risk mitigation layer that operates entirely independently of procurement strategies, storage infrastructure, or financial derivatives. Solar generation displaces thermal fuel consumption structurally and permanently during generation hours, creating a baseline reduction in fuel demand that no market event can eliminate.

This compounding effect operates on multiple dimensions simultaneously:

1. Procurement volume reduction: Lower fuel demand means fewer litres to source, store, and transport across complex logistics corridors.
2. Hedging requirement reduction: A smaller exposed fuel volume requires proportionally less financial hedging to achieve equivalent percentage coverage.
3. Storage pressure reduction: Lower consumption rates extend the operational life of existing storage buffers, reducing urgency in replenishment logistics.
4. Emissions intensity reduction: Lower diesel and HFO combustion reduces greenhouse gas emissions intensity per ounce produced, strengthening ESG metrics relevant to institutional investor mandates.

For investors evaluating B2Gold's long-term cost profile, the solar installations represent a durable structural improvement to AISC, not a cyclical benefit that reverses when fuel prices fall. In addition, this structural resilience complements B2Gold's broader positioning as a producer that treats gold as an inflation hedge for its investors, with operational cost discipline reinforcing that value proposition.

Balance Sheet Strength and Capital Allocation in 2026

B2Gold's ability to execute a proactive multi-mine fuel security strategy rests on the financial foundation that makes advance commitments possible. The company entered Q2 2026 with $479 million in cash and cash equivalents, $171 million in working capital, and a quarterly free cash flow run-rate of $362 million. This liquidity profile is not incidental to the fuel strategy. It is what enables it.

2026 Capital Allocation Priorities

• Completing Phase 1 of the Goose mine crusher upgrades, which will increase processing capacity and throughput efficiency
• Initiating mining at Fekola Regional upon receipt of an exploitation permit, extending the Fekola Complex's production horizon
• Continued shareholder returns through dividends (Q2 2026 dividend declared at $0.02 per share) and share buybacks (20 million shares repurchased year-to-date through Q1 2026)
• Integration of the $325 million cash proceeds from the April 23, 2026 sale of B2Gold's 70% interest in Fingold, which holds claims in Northern Finland

This combination of strong operating cash generation and a well-timed asset divestiture positions B2Gold to fund its capital programme, maintain shareholder returns, and preserve the financial flexibility required for proactive supply chain management across all four producing operations.

Risk Scenarios: Where the Strategy Could Face Pressure

No fuel security strategy eliminates risk entirely. Understanding where B2Gold's framework remains exposed helps investors assess the residual uncertainty embedded in the company's cost guidance.

Scenario 1: Arctic Logistics Disruption at Goose

Adverse ice conditions, vessel scheduling conflicts, or environmental permitting complications could compress the sealift window or delay delivery. The existing storage buffer of more than 80 million litres and the Q3 2025 forward purchase provide a substantial operational cushion, but multi-year disruptions to sealift access would ultimately test the limits of storage-based resilience.

Scenario 2: Supply Chain Stress in Mali

Fekola's landlocked position means regional political or infrastructure events can affect fuel transit times and costs in ways that storage expansion can buffer but not eliminate indefinitely. However, the solar hybridisation strategy reduces total fuel dependency, which diminishes the severity of any supply interruption scenario.

Scenario 3: Sustained Global Diesel Price Escalation

A structural upward shift in global diesel markets would pressure AISC across all four operations. The 36% financial hedge provides partial protection, and solar generation at three sites provides structural insulation, but the remaining unhedged exposure on the thermal fuel component would affect reported costs.

Scenario 4: Site-Specific Operational Events

Events such as equipment failures or facility incidents can disrupt production independently of fuel availability. According to Mining Weekly, B2Gold's diversified four-mine portfolio limits the impact of any single-site disruption on consolidated guidance, as demonstrated by the company maintaining full-year guidance of 820,000 to 970,000 oz despite individual site challenges reported in early 2026.

Leadership Transition and Operational Continuity

B2Gold's Q1 2026 results were the first major reporting milestone under incoming President and CEO Mike Cinnamond, who transitions from his role as Senior VP Finance and CFO. Clive Johnson, who shaped B2Gold's multi-jurisdictional growth strategy over many years, is retiring on June 4, 2026.

Cinnamond's background in financial leadership rather than purely operational roles is relevant to the fuel security discussion. The forward-purchasing model at Goose, the structured hedging programme, and the capital allocation decisions that fund storage expansion projects are all financially intensive disciplines that benefit from CFO-level oversight being embedded at the executive leadership level. The transition preserves strategic continuity in an area where institutional knowledge and procurement relationships carry genuine operational value. Furthermore, as B2Gold secures fuel supply for all mines under new leadership, the institutional frameworks already in place provide meaningful continuity across each jurisdiction.
