In mining and general business accounting,
Capital Expenditure (CapEx) covers the upfront investment to build and equip a facility, while Operating Expenditure (OpEx) covers the ongoing costs of production once operations begin.
CapEx vs. Initial Production Costs
CapEx (Upfront Investment): This covers everything required before production starts. It includes major long-term assets such as machinery, processing plants, infrastructure (roads, utilities), and mine development (access tunnels or stripping).
Initial Production (OpEx): Once the "switch is turned on," the costs to actually produce the first tonne—such as labor, fuel, raw materials, and electricity—are classified as OpEx. These are recurring expenses recorded on the income statement rather than the balance sheet.
Case Study: Kodal Minerals (Bougouni Project)
For the Bougouni Lithium Project, Kodal Minerals successfully separated these costs to manage their budget:
Initial CapEx: Budgeted and spent $65 million to build the Stage 1 Dense Media Separation (DMS) plant and necessary infrastructure.
Ongoing Production (OpEx): The project has an estimated AISC (All-In Sustaining Cost) of $647/t of concentrate produced. This includes the day-to-day costs of running the mine that are not covered by the initial $65 million investment.
Future Expansion: Stage 2 expansion (flotation plant) is estimated to cost an additional $175–$200 million in CapEx, which the company intends to fund using cash flow from Stage 1 production.
