Legal AI for mining contracts does two different jobs, and most mining companies need both. The first is getting the contract right: drafting and reviewing offtake, joint venture, farm-in, royalty, EPC and mining services agreements against the positions you accept. The second is commercial control once it's signed: serving notices inside the window, tracking time bars and checking invoices. GenieAI, Luminance, Spellbook, Harvey, Icertis, Ironclad and LegalOn are built for the first job. Hevi is built for the second, on mining sites specifically.
Here's what each of the eight does, who it suits and where it stops, described from each vendor's own website as checked on November 13, 2026. GenieAI makes Genie, one of the eight, so read the order with that in mind.
1. GenieAI
GenieAI drafts mining contracts from a brief or from your own templates, and reviews the other side's paper against your playbook, rating each clause red, amber or green with a plain-English reason and a link to the clause. Fixes go into native tracked changes in your original Word file, so a JV partner or offtaker receives an ordinary Word redline. Every open point is tracked through the negotiation.
After signing, Libraries files your agreements in one place and Insights builds a table across them: one row per contract, one column per question, such as the notice period for a delay claim, the rise-and-fall review date or the royalty basis, with each cell linked to its clause. Key dates, renewals and notice periods are tracked from the contracts themselves.
- Best for: mining owners, operators and contractors whose in-house legal team sets the positions and whose commercial teams negotiate within them.
- Strengths: drafting and review in one place; several documents read together, so a JV agreement is checked against its side letters and schedules; 150+ jurisdictions on the Enterprise plan.
- Where it stops: it doesn't read site diaries or fleet data, so the event on site still has to be raised by your team. Genie then drafts the notice against the clause it relies on.

2. Hevi
Hevi calls itself "the commercial control layer for mining," built for Tier 1 mining contractors and for mine owners and operators, underground and open-cut. It turns site records into contractual action. It drafts notices such as production relief, latent conditions and delay events from the site's own plods and diaries, citing the clause, so they're "served inside the window." It also checks invoices against the contract, flags instructions given by email that should have become formal variations, prices standby from the schedule of rates and contests KPI adjustments with evidence.
- Best for: mining contractors and owners losing money between the site and the contract.
- Strengths: it starts from site records, the evidence a claim depends on, and it's built for mining.
- Where it stops: its mining page describes life after signature. If you also need help drafting and negotiating the contract, ask what it covers.
3. Luminance
Luminance applies "playbooks and precedent to every review" and gives risk visibility across a contract portfolio, with solutions for legal, procurement, finance and sales teams.
- Best for: large miners with a big contract estate who want precedent from past deals applied to new ones.
- Strengths: portfolio-wide view of risk.
- Where it stops: the pages we read don't mention mining contracts, so test it on an offtake agreement and a mining services contract.
4. Spellbook
Spellbook redlines contracts in Word with every suggestion tracked, and enforces your team's standards as checklists on every review. It's designed for in-house teams and law firms and lists energy among the industries it serves.
- Best for: mining lawyers who redline in Word all day.
- Strengths: works where lawyers already work.
- Where it stops: it's built for lawyers, so check fit if commercial managers will run reviews themselves.
5. Harvey
Harvey serves law firms and in-house teams. For in-house, it reviews contracts "against a preferred playbook, form, or template" and returns drafting changes as tracked changes, in its Word add-in or web app. It has an Energy and Utilities industry page.
- Best for: large legal departments and the firms advising mining companies.
- Strengths: playbook review in Word, plus agents for wider legal work.
- Where it stops: the pages we read don't mention mining, and access is by demo.
6. Icertis
Icertis is an "AI-native contract intelligence platform" built for enterprise. Its agents cover drafting, redlining, playbook creation and risk review, and Vera Obligations offers "audit-ready obligation discovery and tracking." It lists energy among its industry solutions.
- Best for: global miners that want obligations tracked across a very large contract portfolio.
- Strengths: obligation tracking at enterprise scale.
- Where it stops: it's an enterprise platform rollout, and its homepage doesn't mention mining.
7. Ironclad
Ironclad is an AI contract lifecycle management platform covering create, review, approve, sign, store and fulfill, with a Contract Review Agent for redlining and configurable AI Playbooks.
- Best for: mining groups standardizing how procurement and legal handle contracts from request to signature.
- Strengths: workflow, approvals and a searchable repository.
- Where it stops: it's a CLM rollout, sized to match.
8. LegalOn
LegalOn works in Word, generates redlines and offers 135+ attorney-built playbooks plus custom ones built from your guidelines. It has industry pages for construction and engineering, manufacturing and others.
- Best for: in-house teams handling the supply, services and NDA paper around a mine.
- Strengths: playbooks ready on day one.
- Where it stops: its industry list doesn't include mining, so check how its playbooks handle offtake or royalty terms.

The mining contracts that decide your choice
Test any tool on the agreements you'll sign most often. These six carry most of the value and most of the risk.
- Offtake agreements. Quantity and tolerance, product specification, payables and penalties for impurities, the pricing formula and quotational period, sampling and assay with an umpire, delivery terms, and any take-or-pay commitment.
- Joint venture and farm-in agreements. Earn-in stages and expenditure commitments, dilution formulas, the operator's role, management committee voting, sole risk, pre-emption rights and withdrawal.
- Royalty agreements. The royalty basis (gross or net), allowable deductions, audit rights, buy-back options and whether the royalty binds a buyer of the tenement.
- Concession and state agreements. Work commitments, relinquishment, fiscal stability, local content, environmental and closure obligations.
- EPC contracts. Fixed price, delay damages, performance guarantees, variations and the notice regime for claims.
- Mining services contracts. Schedules of rates, rise and fall, KPIs, standby, latent conditions and time bars.
Notices and time bars: where mining contracts lose money
Most mining services and EPC contracts make notice a condition of payment. Under the FIDIC 2017 forms, for example, a contractor must give notice of a claim within 28 days of becoming aware of the event, or it loses the entitlement. Many bespoke mining contracts use shorter windows.
The money's lost in the gap between the site and the contract. A latent condition is found on a Tuesday, the superintendent gives an instruction by email, and nobody checks the notice clause until the invoice is disputed months later. By then the window's closed.
Closing that gap takes two things. You need to know every notice period and time bar in every live contract, which GenieAI's Insights table gives you, each linked to its clause. And you need the event raised from site quickly, which is the ground Hevi covers. Once the event's raised, Genie drafts the notice against the clause it relies on.
How to choose
- Name the job. If contracts are signed on poor terms, start with drafting and review. If good contracts lose money on site, start with commercial control.
- Write your positions down. A playbook for your offtake, JV and services contracts is what every review tool checks against. GenieAI can draft one from your past agreements.
- Test on your own paper. Run a live offtake agreement and a mining services contract through each shortlisted tool and count what it finds.
- Check the notice table. Ask each tool to list every notice period and time bar across ten signed contracts, and check them against the clauses.

Frequently asked questions
Are there legal AI tools built for mining contracts?
A few. Hevi is built for mining specifically and focuses on commercial control after signing: notices, claims, invoices and variations, starting from site records. GenieAI has a mining page and drafts and reviews offtake, joint venture, farm-in, royalty and mining services agreements against your own playbook, and it tracks notice periods and key dates across signed contracts. General contract AI tools such as Luminance, Spellbook, Harvey, Icertis, Ironclad and LegalOn handle mining contracts as they would any commercial agreement, without mining-specific material on the pages we read. Test any tool on a real offtake agreement before you buy.
What should a review of an offtake agreement check?
Start with quantity and price. Check the annual tonnage and tolerance, whether there's a take-or-pay obligation, and the pricing formula, including the reference price and the quotational period. Then check quality: the product specification, payable metal terms, penalties for impurities and the right to reject cargo. Sampling and assay rules matter, including who appoints the umpire. After that come delivery terms, title and risk transfer, payment security, force majeure, term and termination. If the offtake supports project finance, check the lenders' step-in rights. GenieAI flags each of these against your playbook and redlines the fixes in Word.
Can AI track notice periods and time bars?
Yes, on the contract side. GenieAI files your signed contracts in a Library, and Insights pulls every notice period, time bar, rise-and-fall review and termination trigger into one table across all of them, each linked to its clause, so you can see which events on site start a contractual clock. Genie also drafts the notice itself against the clause it relies on. It doesn't read site diaries or fleet data, so the event still has to be raised by your team. Hevi's work starts on site: it drafts notices from plods and diaries, and the two jobs fit together.
How do royalty deductions differ between gross and net bases?
A gross revenue royalty is a percentage of the revenue from the minerals sold, with few or no deductions, so it's simple to calculate and hard to dispute. A net smelter return royalty is a percentage of revenue after allowable deductions, usually smelting, refining, transport and sometimes insurance and penalties. Disputes come from what counts as a deduction, whether related-party charges are at arm's length and how the royalty holder audits the numbers. Check the deductions list closely, the audit rights, payment timing and whether the royalty binds anyone who buys the tenement. A review tool should flag each one.
What should a farm-in review check?
Check the earn-in structure first: the stages, the expenditure each stage requires, the deadline for each and what happens if the farminee stops early. Then look at dilution, because the formula decides who controls the project later. Check who operates during the earn-in, what the management committee decides, and the voting thresholds. Sole risk rights, pre-emption on a sale, the area of interest clause and access to data all need attention, as does the withdrawal process. GenieAI reviews a farm-in against your playbook and reads it with the joint venture agreement it leads into.
Is mining contract data safe in an AI tool?
It depends on the vendor's terms, so check three things: whether your documents can be used for training and how you opt out, whether the vendor's model providers keep your data, and where it's stored. GenieAI may use customer content to improve its models unless you opt out, and you can opt out at any time by emailing help@genieai.co; an admin's opt-out covers the whole workspace. Its model providers, OpenAI and Anthropic, work under zero data retention agreements and never train on your content. Data is encrypted with AES-256 at rest and TLS 1.2 or higher in transit. The detail's on our security page.
