Different Ways to Finance a Mining Project From Exploration to Production
Mining finance is stage-specific. The capital that funds early geology and drilling is not the same capital that funds plant construction or working capital at shipment.
Serious investors do not “fund a dream.” They fund milestones, teams, permits, metallurgy, economics, and a route to monetization.
The fastest way to kill a raise is to pitch the wrong capital for the stage.
Exploration capital is high-risk equity. Construction capital is structured, covenant-heavy, and built around feasibility, permits, contracts, and controls.
If you want money to move, you need the right work product at the right time.
How Investors Underwrite Mining at a High Level
Mining projects are underwritten through evidence, not enthusiasm. The underwriting questions shift by stage, but the structure is consistent.
Geology and Resource Confidence
Is the geology credible, repeatable, and supported by data. Is the resource reported under recognized standards such as JORC or NI 43-101, where applicable.
Metallurgy and Recoveries
Does the ore behave. Are recoveries evidenced by testwork. Is the flowsheet realistic for the orebody and local constraints.
Permits, Social License, and ESG
Are the permits achievable. Is the land position clean. Are there community, environmental, and governance issues that can block development.
Economics and Execution
Is there a credible cost base, build plan, and schedule. Can the team execute. Is there a realistic path to first production and cash conversion.
Stage 1: License, Targeting, and Early Field Work
This phase includes license acquisition, mapping, sampling, geophysics, and initial drilling plans. It is usually funded by founder capital, angels, and specialist seed investors.
If you cannot fund basic work, you will not generate the data needed for institutional engagement.
Common financing tools at this stage
- Founder and seed equity:
small tickets, high risk, high dilution.
- Prospect generator model:
vendor stakes and staged funding from partners in exchange for project interests.
- Farm-in earn-in agreements:
a partner funds exploration spend to earn equity in the project.
Stage 2: Discovery and Resource Definition
Once drill results support a coherent thesis, the goal becomes a defensible resource and the early engineering inputs that let investors model outcomes.
That typically means structured programs of drilling, QA/QC discipline, and reporting under recognized codes where required by your market.
Work products that unlock better capital
- JORC or NI 43-101 reporting:
credibility and comparability for investors.
- Metallurgical testwork:
recoveries, reagent consumption, and flowsheet viability.
- Early economic work:
scoping-level models or a Preliminary Economic Assessment where used.
Funding is still equity-led, but you can start bringing in strategic capital and larger specialist funds, especially if the project fits a known value chain.
Stage 3: Scoping and Pre-Feasibility Planning
This is the transition from “interesting geology” to “engineered development case.”
The purpose is to de-risk the build path, quantify capex and opex at a credible level, and map permitting and infrastructure constraints.
Equity Raises With Real Milestones
Equity remains common, but investors will expect a clear milestone plan, a disciplined budget, and a credible team. Raises without defined work programs price badly.
Strategic and Industrial Partners
Offtakers, processors, and industrial buyers can provide staged capital if the project fits their supply strategy and governance standards.
Royalties and Streams
Royalties and streams can provide non-dilutive style capital, but they are not free money. They reduce future cash flow and require serious diligence.
Convertible and Structured Equity
Some investors use convertibles or staged tranches to manage risk. Terms can become expensive if milestones slip.
Stage 4: Feasibility, Permits, and the Capital Stack
By feasibility stage, the conversation shifts to capital stack design. Construction funding is not “capital raising” in the abstract.
It is a package of interlocking agreements, covenants, controls, and conditions precedent.
| Capital source |
What it typically funds |
What it usually requires |
| Senior secured debt
|
Construction and long-lead equipment, sometimes working capital |
Feasibility-level studies, permits progress, security package, covenants, robust reporting |
| Mezzanine and structured debt
|
Equity gap and capex layering |
Higher pricing, tighter controls, intercreditor arrangements |
| Offtake-backed prepayments
|
Working capital and sometimes capex support |
Credible offtake, delivery mechanics, controls over receivables and flows |
| Royalties and streams
|
Development capital without standard debt amortization |
Technical diligence, legal title comfort, downside protection for the provider |
| Equipment finance
|
Specific mobile or plant equipment |
Asset security, supplier terms, service and maintenance discipline |
| Equity and strategic equity
|
Development equity, contingency, and sponsor alignment |
Governance, board control, dilution acceptance, clear use of proceeds |
Stage 5: Production, Working Capital, and Scale
Production does not end the financing story. It changes it. Once you ship, the core questions become working capital, receivables, inventory control, hedging, and operational discipline.
Concentrate and metal supply chains can support borrowing bases and receivables facilities, but only when documentation, controls, and counterparties are clean.
Common production-stage facilities
- Working capital revolvers:
to fund the cash conversion cycle between cost and receipt.
- Borrowing base facilities:
secured by receivables and eligible inventory under controls.
- Offtake-linked facilities:
where a credible buyer and settlement mechanics reduce risk.
- Hedging programs:
to manage price risk, often required by lenders.
Exit Planning: Liquidity Is a Strategy, Not a Surprise
Mining exits are rarely accidental. The credible routes are familiar: a strategic sale, a public listing where appropriate, or liquidity via royalties and streams.
The common failure is raising money without a route to the next milestone, then trying to sell a story instead of a plan.
Strategic Sale
A logical outcome for projects that fit a major’s footprint, processing route, or supply chain. Requires data quality, governance, and clear title.
Public Markets
An IPO or reverse takeover can work for the right assets and teams, but it does not replace technical credibility. It increases disclosure and governance demands.
Royalties and Streams
A liquidity option that can complement or substitute for parts of the capital stack, trading future upside for current certainty.
Refinancing After De-Risking
As milestones are achieved, cost of capital can fall. Repricing and refinancing are normal when the project profile materially improves.
