A mineral deposit can be worth hundreds of millions of dollars on paper and still leave its owner unable to pay a drilling contractor. Reserves in the ground cannot be sold on an exchange, deposited at a bank or handed to a lender as a cheque. They only become cash when someone with capital is persuaded that the metal can be extracted, processed, sold and paid for, on a timeline and at a cost they can underwrite.
This guide explains how that conversion actually happens. It covers the reporting standards that turn geology into a bankable asset, the main financing routes (offtake prepayments, streams and royalties, reserve-based and project lending, government-backed capital, and partial asset sales), and what capital providers look for before they commit.
Why mineral reserves are illiquid
Value in the ground is a forecast, not a balance.
An undeveloped deposit generates no revenue. Its value depends on grade, tonnage, metallurgy, mining method, capital cost, operating cost, commodity prices, permits, infrastructure and the jurisdiction's legal stability. Every one of those variables is a risk a financier has to price before any money moves.
There is no deep secondary market for a mining licence.
Unlike listed equities or warehoused metal, a licence or concession usually has a small pool of credible buyers, each of whom will run months of technical and legal diligence. Transfers often need ministerial or regulatory consent, and change of control clauses in mining codes can add further approvals.
The asset cannot be pledged in the simple sense.
Many jurisdictions vest subsoil minerals in the state, so what the company owns is a right to extract, not the minerals themselves. Lenders take security over the licence, the project company's shares, the plant, the bank accounts and the sales contracts. They do not take security over "the reserves" as a standalone object, which is why the financing always comes back to the cash flows the reserves can produce.
The current market makes the conversion easier for the right assets. The IEA Global Critical Minerals Outlook 2026
reports that critical mineral prices rebounded in 2025 and early 2026, with lithium prices more than doubling, cobalt rising by around 130 percent after Congolese export restrictions, and copper reaching record highs. Higher prices and supply security concerns have widened the pool of buyers, traders and governments willing to commit capital to deposits outside the most concentrated supply chains.
From resource to reserve: making the asset bankable
Financiers fund reserves, not stories.
Most serious capital providers rely on estimates prepared under a code aligned with the CRIRSCO International Reporting Template, such as JORC in Australasia, NI 43-101 and the CIM Definition Standards in Canada, SAMREC in South Africa or PERC in Europe. These codes separate exploration results from Mineral Resources (Inferred, Indicated, Measured) and from Mineral Reserves (Probable, Proved), the economically mineable portion supported by at least a pre-feasibility study.
The United States follows the same logic.
Under Regulation S-K 1300, adopted by the SEC in October 2018, a registrant's disclosure of resources and reserves must rest on a technical report summary signed by a qualified person. For a private owner seeking finance, an equivalent independent report is the starting point of every credible conversation.
The practical consequence is simple. An Inferred Resource can attract equity and some early-stage royalty capital. A Probable or Proved Reserve backed by a feasibility study, permits and a credible offtake path can attract debt. Moving the asset up that ladder is usually the single biggest lever an owner has on the amount and cost of capital available.
The main ways to monetize reserves
Each route trades a different slice of the asset's future value for cash today. Most real transactions combine two or more of them.
Sell future production
Offtake prepayments, streams and royalties advance cash against metal that has not yet been mined. They are often the fastest non-dilutive capital available to a near-production asset and are frequently structured through structured commodity finance.
Borrow against the reserves
Senior project loans and reserve-based facilities lend against the forecast cash flows of the mine, with security over the licence, plant and contracts. Sizing is driven by cover ratios, not the headline in-situ value. See our approach to project finance.
Bring in state-backed capital
Export credit agencies and development finance institutions now treat critical minerals as strategic. Their participation can lengthen tenors and crowd in commercial banks, sometimes alongside credit enhancement
such as guarantees or political risk cover.
Sell or share the asset
A partial sale, joint venture or earn-in hands a portion of the deposit to a partner in exchange for cash or funded work. It is dilutive at the asset level but can unlock development without adding debt.
Comparing the routes side by side
| Route |
What the owner gives up, and when it fits |
| Offtake prepayment |
Commits a share of production to a trader or smelter, usually at market-linked pricing, and repays the advance through deliveries. Fits assets in production or within roughly 12 to 24 months of first concentrate. |
| Stream |
Sells a percentage of a metal, often a by-product, for an upfront deposit plus a fixed or percentage-of-spot payment on delivery. Fits development or producing assets with meaningful precious metal or cobalt credits. |
| Royalty |
Grants a percentage of revenue or net smelter return for a single upfront payment. Available earlier in the asset's life, including some pre-development stages. |
| Senior project or reserve-based debt |
Adds leverage, covenants, reserve tails and security packages. Fits assets with a bankable feasibility study, permits, offtake and an equity contribution. |
| ECA or DFI participation |
Adds policy conditions such as offtake destination, environmental and social standards and procurement rules. Fits strategic minerals in eligible jurisdictions. |
| Partial sale or joint venture |
Gives up ownership and some control. Fits owners who lack development capability or need to fund a feasibility study before any debt is possible. |
Offtake prepayment finance
Traders pay today to secure tomorrow's tonnes.
In a prepayment, a commodity trader or smelter advances cash to the producer and is repaid from the sale proceeds of concentrate delivered under a linked offtake contract. The trader takes performance risk on the mine and in return secures supply, marketing margin and often a financing spread.
The structure has become standard in copper. Fastmarkets reported in January 2026
that Mercuria agreed a USD 250 million prepayment with Bulgaria's Geotechmin alongside an offtake for all of the Ellatzite mine's 2026 copper concentrate. In February 2026, Orion Minerals executed a USD 250 million prepayment facility with Glencore
to fund the restart of its Prieska copper and zinc mine in South Africa, settled through concentrate deliveries.
What drives the terms.
Prepayment size is set by forecast deliveries, price assumptions, the trader's credit appetite for the jurisdiction and the strength of collection mechanics such as offshore collection accounts and assignment of receivables. Intercreditor arrangements matter, as the Prieska deal shows, because prepayments often sit alongside streams, royalties or development finance. For a deeper look at how these structures are assembled, see our guide to physical commodity trading and structured trade finance.
Streams and royalties
A stream buys metal, a royalty buys revenue.
Under the model described by Wheaton Precious Metals, the streamer pays an upfront deposit for a percentage of a mine's metal production, plus an ongoing payment per unit when the metal is delivered. The miner treats the deposit as non-dilutive capital. A royalty, by contrast, is a single upfront payment for a percentage of revenue or net smelter return, with no ongoing payment per unit.
Streams are most efficient where the target metal is a by-product. A copper miner that also produces gold or silver can monetize metal that sits outside its core business case, often at a better valuation than the equity market would give it. Ticket sizes can be large. Nasdaq reported in 2026
that Wheaton provided USD 300 million upfront for a gold stream as part of a wider financing package when an asset changed hands from Barrick.
The hidden cost.
Streams and royalties are senior claims on production that survive refinancing and often a sale of the mine. They reduce the cash flow available to future lenders, so they need to be sized with the full capital structure in mind rather than as a quick fix.
Reserve-based lending and project finance
Oil and gas has the template.
Reserve-based lending is most developed in upstream oil and gas, where banks lend against a borrowing base recalculated periodically from engineered reserve reports. The OCC's Comptroller's Handbook on oil and gas exploration and production lending
sets out how examiners assess these collateral-focused facilities, including reserve depletion and the treatment of different reserve categories.
Mining usually relies on project finance instead.
Hard rock deposits are less homogeneous than oil fields, so mining debt is typically sized as limited recourse project finance. Lenders model the mine plan, apply price decks and stress cases, and set the loan by debt service coverage, loan life coverage and a reserve tail, meaning a portion of reserves must remain after the loan is repaid. Expect requirements for completion support, a debt service reserve account, hedging and cost overrun facilities.
This is where preparation pays off. A credit memo, model review and sources and uses that already answer a lender's first round of questions can shave months off a process. That is the purpose of our Lender-Ready Package, and our project finance advisory deliverables
show the full path from bankability assessment to financial close.
Export credit and development finance
Critical minerals are now a policy priority, and capital follows policy.
The Export-Import Bank of the United States runs a Supply Chain Resiliency Initiative
that finances overseas critical minerals projects. EXIM explains on its SCRI guidance page
that projects need signed offtake contracts with US buyers, and that the amount it can finance is linked to the size of that offtake.
The US International Development Finance Corporation has moved further up the capital structure. In a 2026 press release, DFC confirmed it had closed a USD 600 million investment in the USD 1.8 billion Orion Critical Mineral Consortium. Mining Weekly reported in October 2026
that DFC holds more than USD 3 billion of critical minerals commitments in Africa and plans more direct equity investment.
European, Canadian, Japanese, Korean and Australian agencies run comparable programmes. Their involvement rarely replaces commercial lenders. It typically extends tenor, absorbs political risk and gives banks the comfort to commit, provided the project meets environmental, social and governance standards and the agency's eligibility rules.
Selling part of the asset
Dilution at the asset level can be cheaper than dilution at the company level.
Owners without the balance sheet to fund a feasibility study often farm out a stake through an earn-in, where a partner funds a defined work programme in exchange for an increasing interest. A straight partial sale or joint venture with a strategic buyer, smelter or trader can also bring cash, technical capability and offtake in a single transaction.
The trade-off is control. Joint venture agreements need careful drafting on funding obligations, dilution formulas, operatorship, pre-emption rights and marketing of product. An owner who gives these away cheaply at the exploration stage can find the most valuable phase of the asset's life captured by a partner.
Combining routes into one capital stack
The best outcomes come from sequencing, not from a single cheque.
A typical development path might use a royalty or earn-in to fund the feasibility study, a stream on by-product metals to cover part of construction, a trader prepayment tied to the first years of concentrate, and senior project debt with ECA or DFI cover for the balance. Each layer is priced against the risk it takes, so the blended cost of capital falls as the asset de-risks.
Order matters.
A royalty or stream granted early reduces the cash flow available to senior lenders later, and a prepayment with broad security can block a project finance package. Structuring the stack from the top down, with the senior debt case in mind from day one, protects the owner's equity and keeps every financing option open.
What capital providers need to see
Technical.
An independent resource and reserve statement under a recognised code, signed by a competent or qualified person, plus the study (scoping, pre-feasibility or feasibility) that supports it, metallurgical test work and a mine plan.
Legal.
Clear title to the licence or concession, evidence of good standing, permits issued or a credible permitting timeline, surface rights and any community agreements, and a review of the mining code's rules on transfer, change of control and security.
Commercial.
Offtake terms or strong market evidence, a logistics route to port or smelter, power and water supply, and a realistic capital and operating cost estimate.
Financial.
A financial model with price decks and sensitivities, a sources and uses table showing the sponsor's equity contribution, existing encumbrances such as royalties or streams, and audited accounts for the project company and sponsor.
Owners who arrive with all four strands in order are negotiating terms. Owners who arrive with a licence and an in-situ value estimate are usually still negotiating whether anyone will look at the deal. Our debt underwriting services
are designed to close that gap before an asset goes to market.

Frequently asked questions
Can I borrow against mineral reserves that are still in the ground?
Yes, but lenders lend against the cash flows the reserves can produce, not their in-situ value. That requires a reserve statement under a recognised code, a feasibility-level mine plan, permits, an offtake path and a sponsor equity contribution. Without these, early capital usually comes from equity, royalties or partners.
What is the difference between a mineral resource and a mineral reserve?
A Mineral Resource is a concentration of minerals with reasonable prospects for eventual economic extraction. A Mineral Reserve is the economically mineable part of a Measured or Indicated Resource, supported by at least a pre-feasibility study that applies mining, processing, economic, legal and environmental modifying factors.
Is a stream or a royalty better than debt?
Neither is better in the abstract. Streams and royalties are non-dilutive and carry no repayment schedule, but they are long-term claims on production that reduce cash flow for future lenders. Debt is cheaper when the asset is bankable but brings covenants and repayment risk. Most developers use a combination sized against the full capital structure.
How quickly can reserves be turned into cash?
A prepayment for a producing mine can close in a few months if the technical and legal files are in order. Project finance for a development asset commonly takes far longer because of feasibility work, permitting, lender diligence and documentation. Timelines depend heavily on how complete the owner's information is at the start.
Does Financely lend directly against mining assets?
No. Financely is an advisory and arranging firm. We assess, structure and prepare the transaction and introduce it to suitable lenders, traders, streamers and institutional investors, who make their own credit decisions.
