Beyond the Spreadsheet — Enterprise Finance Inside the Engineering Loop

The legacy model: finance as an afterthought

In the traditional workflow finance happens last: a modeller builds a fresh spreadsheet, types in factored cost assumptions and produces a static NPV, disconnected from the engineering. The model is opaque, fragile, and structurally disconnected from the cost of a tonne.

The IMC model: finance native to the loop

Through MiningIQ, enterprise finance is part of the optimisation loop. Built on a strict separation of inputs, calculations and outputs and a chart of accounts mapped to statement line items, but purpose-built for mining, it produces:

• Complete three-statement output — income statement, balance sheet and cash flow, period by period across life of mine, where the balance sheet balances and cash flow reconciles.
• Multi-jurisdiction fiscal modelling — corporate tax, royalties, mining levies, loss carry-forward, interest-deductibility caps and tax depreciation, with effective government take.
• Instrument-level financing — drawdowns, repayment profiles, grace periods, covenant and DSCR monitoring, and automatic peak-funding identification.
• Bayesian (correlated) risk analysis — thousands of full-model evaluations with realistic correlation, producing calibrated P10–P90 distributions, not naive Monte Carlo.

The differentiator: FAST- and Modano-structured output

Here is what sets IMC apart. The model exports a fully structured workbook in the two modelling standards large accounting and advisory firms actually use:

• F1F9 / FAST standard — one row, one unit, one formula; left-to-right time axis; dedicated input/calculation/output sheets; check rows that must sum to zero; the blue-input / black-formula / green-link / red-check colour code; cross-sheet references emitted as live formulas, never dead pasted values.
• Modano BFS standard — the modular F-C-W-P layout (cover, scenario switcher, macro/price decks, assumptions, schedule, calculation bridge, annual and monthly three-statement output, and a headline result sheet with NPV, IRR, FCF and payback) in Modano’s classic colour conventions.

Because the export is built from the same engine that ran the study, the workbook a lender’s adviser or a Big-4 auditor receives is the live model, in the format they already know, with the audit trail intact.

Closing the loop: from MineCost to the financial statements

Operating and capital costs flow from MineCost’s zero-based work breakdown structure into the financial model through a controlled, version-tracked mapping to the chart of accounts — so the cost of a tonne in the income statement traces back to the rimpull curve of the truck that moved it.

Techno-economic model vs corporate financial model

There is a structural difference most clients only discover late, and it decides whether your study is financing-ready. Mining engineering firms typically stop at a techno-economic model (TEM) — essentially a single-tab discounted-cash-flow sheet that returns project-level, often pre-tax, NPV and IRR from their cost estimate. A TEM is not a corporate financial model: it does not produce a fully dynamic three-statement model (income statement, balance sheet and cash flow), instrument-level debt structuring and DSCR, proper tax-shield and multi-jurisdiction fiscal treatment, or the accounting architecture lenders require.

For project finance or an equity raising, a TEM is not enough — so the traditional path forces you to hire a second firm (a corporate financial adviser or accountant) to take the engineering firm’s flat numbers and rebuild them into a proper financial engine. That hand-off is slow, costly, and breaks the audit trail back to the mine physics.

IMC closes that gap in one workflow. The MiningIQ enterprise model is an institutional-grade, three-statement corporate financial model — instrument-level debt (drawdowns, repayments, covenants, DSCR), multi-jurisdiction tax, and correlated Bayesian risk — built to the FAST and Modano conventions and tied directly to the block model and haulage physics. You get a complete, lender-ready financial asset from day one: more bankable, and cheaper to execute, because there is no second firm to engage and no rebuild.

Speed is the by-product — bankability is the point

Running hundreds of what-if scenarios quickly is the headline, but it is not the real advantage. The real advantage is that the model is more bankable. A legacy study hands a lender a static, hand-built spreadsheet whose cost and revenue assumptions cannot easily be traced back to the engineering — a lender’s independent engineer cannot reproduce it without rebuilding it. IMC hands over an auditable model in the FAST and Modano conventions, where every number traces from the block model and haulage physics through MineCost to the financial statements — the format banks’ modelling teams and Big-4 auditors already work in, with live formulas and check rows. For project finance and an ITR, that traceability is what makes the model defensible, not just fast.

Why this beats a static spreadsheet for financing

• Reproducible by the lender’s adviser — the independent engineer can follow and re-run the logic rather than take it on trust.
• One source of truth — a change to the mine sequence flows automatically to opex, capex and cash flow, so the model the investment committee sees is internally consistent, with no version-drift between disconnected spreadsheets.
• Correlated (Bayesian) risk — calibrated P10–P90 economics a credit committee can stand behind, not naive single-point or independent Monte Carlo outputs.
• Lender- and auditor-native formats — FAST and Modano workbooks, so diligence is faster and the model is trusted on sight.

So the integrated model is both the most agile and the most bankable option — you do not trade speed for financing credibility. (See The Modern Bankable ITR and From Block Model to Corporate NPV.)
