TerraFiscal models the taxes, royalties, and economic rent of Canadian mineral and resource projects — and labels each number by where it came from. Public disclosure, model-derived estimate, or a gap that needs to be requested. No figure pretends to be more certain than it is.
Most mining fiscal estimates present a single confident number. The hard part isn’t the arithmetic — it’s that the inputs that move the result most, like mine-level tax-pool balances, are usually not public. TerraFiscal treats that uncertainty as a first-class output instead of hiding it.
British Columbia, Alberta, Saskatchewan, and Québec — each with its own mechanics: BC’s NCP/NR tax and cumulative expenditure accounts, Saskatchewan potash, Alberta post-payout net revenue, Québec’s greater-of mining duties and minimum mining tax.
A cost can be deductible for one tax regime and not another, capitalized rather than expensed, or require legal review. TerraFiscal classifies each cost line and flags the ones that need a specialist’s sign-off rather than guessing.
Where public filings report outcomes but not inputs, the platform works backward — inferring tax-pool movements and effective rates from disclosed figures, and labelling every reconstructed value as exactly that.
Source explanations, review decisions, and approvals are written to an append-only, replicated audit store. The reasoning behind a number is recoverable months later — which is what negotiation and assurance contexts require.
The same four labels run through every model, every report, and every export. They are the vocabulary of the product — and the reason its outputs can be relied on in rooms where the stakes are real.
Backed by a public document — an annual report, technical report, regulatory registry, or government filing.
Computed by the platform from public and supplied inputs, with the calculation path retained for audit.
Reasoned from indirect evidence where direct disclosure is missing — and labelled so the reader can weigh it.
A gap. The figure isn’t known, and the platform generates the exact request to put to the company, province, or community.
A value that can’t be computed is reported as not computed — never quietly rendered as $0.
An aggregate inherits the source status of its least-certain input, so one gap can’t hide behind strong data.
Interpretive calls are flagged for legal or tax review rather than presented as settled fact.
Each report is generated from the same source-audited model, so the figures in a briefing match the figures in the audit trail behind them.
A structured briefing on a mine or project built from public information — ownership, production, fiscal regime, and the relevant Indigenous context. Missing inputs become a clear list of questions to ask, not blank cells.
What the public record shows, what had to be inferred, what is missing — and the exact requests to send each party to close the gaps, ranked by how much each one moves the result. It turns uncertainty into a negotiation tool.
Economic development corporations, negotiation teams, and the consultants and counsel who support them on benefit agreements and revenue sharing.
Provincial revenue and policy analysts who need mine-level fiscal estimates grounded in disclosure and clearly separated from inference.
Practices advising on mining transactions, royalties, and fiscal terms who need an audit trail behind every figure they rely on.
TerraFiscal is working with a small number of early partners on source-audited fiscal analysis for specific projects. If your work touches mining fiscal terms, royalties, or benefit agreements, I’d like to hear what you’re up against.
