Mining Joint Ventures: Farm-In, Earn-In, Free Carry

Why Mining Ventures Are Structured as Joint Ventures

Mineral exploration and development pair two things that rarely sit in the same company: ground, and the capital to test it. A junior may hold prospective tenements it cannot fund; a larger party may have capital and technical capacity but no access to that ground. The joint venture is the standard mechanism for combining them without an outright sale.

What a JV achieves that a sale does not

• The tenement holder retains exposure to discovery upside instead of crystallising value early.
• The incoming party stages its commitment against results rather than paying upfront for unproven ground.
• Technical and country risk is shared, which matters in jurisdictions where permitting is the binding constraint.
• Government or community participation can be accommodated through a carried interest.

The trade-off

In exchange you accept a long-term relationship with a counterparty whose interests will diverge from yours the moment the project succeeds or stalls. Almost every difficult JV clause — dilution, sole risk, deadlock, exit — exists to manage that divergence.

Unincorporated or Incorporated: Choosing the Vehicle

This decision drives tax treatment, liability, financing and exit, and is difficult to reverse.

Practical drivers

Parties that need to report reserves or take physical product usually prefer an unincorporated structure. Ventures raising project debt, or with more than two participants, tend toward a company for the governance clarity. Where the tenement cannot easily be transferred into a vehicle without ministerial consent, that consent requirement often decides the question on its own.

Farm-In and Earn-In Mechanics

An earn-in converts expenditure into equity. The drafting question is precisely what triggers vesting.

The core variables

• Expenditure commitment — the amount and the period. Distinguish a firm minimum commitment from optional further stages.
• Qualifying expenditure — define it. Disputes commonly turn on whether overheads, management fees, in-kind services and pre-agreement spend count.
• Vesting — staged as expenditure is incurred, or only on completing a stage. Staged vesting protects the incomer; completion vesting protects the holder.
• Milestones beyond spend — a resource estimate, a feasibility study or a decision to mine may be required in addition to money.
• Withdrawal — what the incomer forfeits, and what it must leave behind: data, reports and rehabilitation of its own disturbance.

Failure to complete

Specify the consequence precisely. Options include forfeiting all rights, retaining a pro-rata interest for expenditure actually incurred, or converting to a royalty. Silence here produces the argument that the incomer has an equitable interest reflecting its spend, which is exactly the ambiguity the agreement exists to prevent.

Free Carried Interest and Who Pays for It

A free carry gives a party equity without early cost. It appears where one side contributes ground instead of cash, and where a state takes a participating interest as a condition of tenure.

The terms that determine its real value

• Duration — carried to a decision to mine, to first production, or to a stated expenditure ceiling.
• Repayment — whether carried costs are recovered from the carried party's share of production, and at what interest rate. A carry repayable from production is a loan, not a gift, and its economics differ sharply.
• Post-carry election — when the carry ends the carried party must either start contributing or accept dilution. Set out both paths.
• Voting rights during the carry — a carried party with full veto rights but no funding obligation can stall a project it is not paying for.

Cash Calls, Dilution and Sole Risk

Funding provisions are where JVs are tested. A partner that cannot or will not fund is the ordinary case, not the exception.

Sole risk in practice

Sole risk lets a party that believes in a programme the other declines to proceed alone, earning either a premium recovery from production attributable to that programme or an increased interest. It keeps projects moving where one participant is capital-constrained. It also creates real complexity: be explicit about which areas and depths the programme covers, how attributable production is measured, and whether the abstaining party can later buy back in and on what terms.

Governance, Operator and Deadlock

One party operates; all parties supervise. The line between those roles causes most day-to-day friction.

The operator

• Scope of authority, and the expenditure limits above which approval is required.
• Standard of care, and whether liability is limited to gross negligence or wilful misconduct.
• Cost recovery and any management fee, plus audit rights over the operator's accounts.
• Removal — for cause, for insolvency, or on losing majority interest.

Deadlock

With two participants at fifty per cent each, deadlock is a structural certainty. Provide for it before it happens: escalation to senior executives, then expert determination for technical questions, then a defined exit such as a shotgun clause, put and call arrangement, or a mechanism where the programme proceeds on sole risk. A JV with no deadlock provision resolves disputes by litigation, which is slower and more expensive than any of these.

Transfers, Pre-Emptive Rights and Exit

You choose your original partner. Transfer provisions decide whether you get to choose your next one.

Standard protections

• Pre-emptive rights — a right of first refusal over an interest being sold, with a workable notice and response timetable.
• Change-of-control provisions — otherwise a partner is replaced in substance by selling its holding company.
• Permitted transfers — usually intra-group, conditional on the transferee assuming the obligations and the transferor remaining liable.
• Tag and drag rights — where a majority sale is contemplated.
• Consent requirements — remember the regulator: transferring an interest in a tenement typically needs ministerial approval and registration regardless of what the JV agreement says.

Partner Due Diligence: The Step Most Often Skipped

A joint venture is a multi-year relationship with shared liability. The diligence customary for a single cargo purchase is not sufficient for it, yet many ventures are entered into on the strength of an introduction and a technical report.

What to verify before signing

• Legal existence and identity — registry-confirmed incorporation, and the signing entity matching the party named in the agreement.
• Beneficial ownership — who ultimately controls the partner. Layered structures that obscure control are a risk in their own right and can create sanctions exposure later.
• Sanctions and PEP screening — the entity, its directors and its UBOs, re-screened periodically because listings change during a JV's life.
• Financial capacity — audited accounts and evidence of ability to meet cash calls. A partner that dilutes to nothing in year two leaves you funding the project alone.
• Tenement position — where the partner contributes ground, confirm they are the registered holder and the ground is unencumbered. See our tenement due diligence checklist.
• Track record — litigation, regulatory breaches, and how previous ventures ended.

Protect the introduction first

If you are introducing a JV opportunity rather than participating in one, secure your position before disclosure. A mining NCNDA stops the recipient dealing directly with the tenement holder, and Lodfy generates it alongside the agreements you will need once terms are agreed.

Frequently Asked Questions

What is the difference between a farm-in and an earn-in?

The terms are used loosely and often interchangeably. Conventionally, a farm-in is described from the incoming party's perspective — they farm into ground held by another — while a farm-out describes the same transaction from the holder's side. An earn-in emphasises the mechanism: the incoming party earns a defined percentage by spending an agreed amount on exploration or development. What matters is not the label but the expenditure milestones, what happens on failure to meet them, and whether the earned interest vests in stages or only on completion.

What is free carried interest in a mining joint venture?

A free carried interest entitles one party to a percentage of the venture without contributing to costs up to a defined point — often until a decision to mine, or up to a stated expenditure threshold. It is common where a party contributes the tenement rather than capital, and where governments take a participating interest. The critical terms are when the carry ends, whether carried costs are repayable out of production, and what happens if the carried party then declines to contribute.

Should a mining JV be incorporated or unincorporated?

An unincorporated joint venture gives each participant a direct undivided interest in the assets and its own tax treatment, which suits parties wanting to book reserves and manage their own share of output. An incorporated JV places assets in a company, offering clearer limited liability, simpler third-party financing and a cleaner exit through share transfer, at the cost of flexibility and an extra tax layer. Exploration-stage ventures are commonly unincorporated; development and production ventures more often use a company.

How does dilution work if a JV partner cannot fund a cash call?

Most agreements allow the non-contributing party's interest to be diluted according to a formula that compares contributions to date. Straight-line dilution reduces the interest proportionately; punitive formulas reduce it faster. Many agreements also convert an interest to a royalty once it falls below a threshold, commonly around five per cent. Check whether dilution is automatic or requires notice, whether there is a cure period, and whether the diluted party retains information and audit rights.

What due diligence should I do on a joint venture partner?

Verify the entity legally exists and matches the party signing; map beneficial ownership to identify who actually controls it; screen the entity, directors and UBOs against sanctions and PEP lists; confirm financial capacity to meet cash calls, since a partner who cannot fund is the most common practical failure; and check litigation and regulatory history. Where the partner contributes the tenement, confirm they are the registered holder and that the ground is free of undisclosed encumbrances.
