What a mining option agreement actually promises

Almost every junior mining transaction in Canada starts the same way. Somebody holds claims and cannot fund them. Somebody else has money and wants exposure. The bridge between them is an option agreement, and it is one of the few commercial documents where being unbalanced is the correct drafting outcome.

What the optionee typically has to do to vest

What you are agreeing to pay comes in three currencies, staged over two to four years:

• Cash — an initial payment on signing, then instalments on anniversaries.
• Shares — often a concurrent private placement in the optionee, sometimes units with warrants, which gives the optionor upside without the optionee spending cash.
• Exploration expenditure — an aggregate commitment over the option period, frequently with a hard physical milestone attached, such as a stated number of metres drilled by a stated date.

Work programmes and budgets usually go through a technical committee, and the optionee typically acts as operator during the option period. If you are the optionor, that is worth noticing: for the next three years someone else is running your ground.

The clause that carries the weight is short. Well-drafted Canadian agreements say the document is “an option agreement only” and that until exercise nothing in it obliges the optionee to do anything further. That is the clause the optionee is buying.

Why the distinction is worth $10 million

798839 Ontario Limited v. Platt concerned mining claims in northern Ontario. Investors advanced roughly $10.8 million through the optionee. The optionee did not satisfy the conditions precedent to vesting. It received nothing, and about $1.2 million came back. The Court of Appeal dismissed the appeal.

The reasoning that matters for drafters is that the money and the exploration work were characterised as the price of the right to earn the interest, not as evidence of having acquired one. The court acknowledged the harshness and enforced the terms anyway. It did not relieve against forfeiture on fairness grounds.

Turn it around and you have the optionor’s side of the same clause. If the optionee’s spending commitments are drafted as covenants, the optionor has a damages claim for the unspent balance when the optionee abandons. If they are drafted as conditions, the optionor’s only remedy is that the option lapses and it keeps whatever has been paid and whatever work has been done. Those are radically different outcomes from what reads, on a first pass, as the same set of numbers.

Vesting into a joint venture, and then dilution

On exercise the parties usually move into a joint venture, with initial participating interests matching what each has contributed — a 100% earn-in leaves the optionor with a royalty, while a staged earn-in to 51%, 70% or 80% forms a JV. Post-vesting terms in Canadian deals are still commonly expressed to be based on the Rocky Mountain Mineral Law Foundation Form 5A.

Then the interesting part: what happens when one party stops funding.

Straight-line dilution is the Canadian default. A party’s participating interest is recalculated as its cumulative contributions over total cumulative contributions, so a party that elects to underfund an approved programme simply ends up owning proportionately less.

Penalty dilution is what applies on a genuine default rather than an election — typically double dilution, so a missed cash call costs twice what the arithmetic would suggest. Whether your agreement distinguishes a good-faith election to underfund from a failure to meet a cash call, and applies different formulas to each, is worth checking before you need to know.

Conversion. Most Canadian JV agreements provide that once a party’s interest falls to 10% or less, it automatically withdraws and assigns its interest to the remaining party in exchange for a net smelter return royalty, commonly 2%, with the other party often holding a right to buy down half of it for a fixed sum. A minority participant that never funds a programme is therefore on a defined path out of the ownership structure and into a royalty, and it should understand the arithmetic of that path on day one.

Net smelter returns: the fight is usually about “net”

An NSR pays a percentage of the value of production or of net proceeds received from a smelter or refinery. The recurring disputes are about what comes off before the percentage is applied: smelting and refining charges, penalties for deleterious elements, transport, insurance, hedging losses, and — the one that generates the most heat — marketing or off-take charges from an affiliate of the operator.

Worth being straight about the state of the law: I have not found a reported Canadian appellate decision squarely deciding a dispute over permissible NSR deductions. The litigated Canadian law on royalties is about something else, and arguably something more dangerous.

Does the royalty survive a change of owner? In Third Eye Capital Corporation v. Ressources Dianor Inc., 2019 ONCA 508, the Ontario Court of Appeal applied the two-part Dynex test: the language must be precise enough to show the parties intended to grant an interest in land, and the interest out of which the royalty is carved must itself be an interest in land. Whether the royalty is calculated on revenue or profit, and whether the holder has any right to extract, do not defeat interest-in-land status where the intention is clear. That characterisation decides whether a royalty can be extinguished by a vesting order in an insolvency.

The cautionary tale is Anglo Pacific Group in Quebec, where a conventional NSR registered only in the provincial mining register was held to create a personal right rather than a real right — and so was unenforceable against a subsequent owner. A royalty is only as good as the way it was created and recorded. Quebec practitioners have been rewriting NSR agreements around that decision ever since.

Recording your interest in Ontario

The Mining Lands Administration System has run Ontario’s claim registry since April 2018, and most of it is self-directed. A claim transfer is done online with no ministry consent and no fee — and note that the transferee has 10 days to accept, or the transfer expires.

What is not online is the thing an optionee most needs recorded. The Ministry’s own guidance is explicit that agreements, debentures, writs and liens “are still filed offline in paper format.” All parties must sign, the document must be dated and list every affected claim, and the fee is $15 per claim.

Fifteen dollars a claim and a paper filing is not a large piece of work. It is, however, the difference between an optionee with a recorded interest and an optionee holding a contract against a counterparty that has since sold the ground.

The four questions to ask before signing

Is it actually an option? Find the “option only” clause, then read every operator and maintenance covenant in the agreement against it. The carve-out at the front of that clause is where obligations hide.

Are the spending commitments conditions or covenants? This is the single question that determines what abandonment costs.

What does dilution actually do? Model the case where you skip two programmes. If you land under 10%, you are a royalty holder, not a partner.

Is the royalty drafted as an interest in land, and is it recorded? Both halves. Precise granting language that never gets recorded, and a recording that rests on loose language, fail in the same way and at the same moment — when the property changes hands.
