This section assesses the plan from the perspectives that matter most to lenders and equity investors: debt-service cover, capital efficiency, and risk-adjusted returns, with copper price as the central sensitivity throughout.

Debt-service cover strengthens from 1.22x in the Year-1 ramp to 1.82x by Year 5. The Year-1 level is tight, as expected in the ramp year, and is supported by a debt-service reserve account funded at close; cover is comfortable from Year 3 onward. Return on capital employed crosses the cost of debt in Year 3 and reaches 23% by Year 5.
Returns and the copper-price sensitivity
On the base case, US$12,000/tonne copper and a 5.0x EV/EBITDA exit on Year-5 EBITDA, the plan delivers a five-year equity IRR of approximately 32%, a money multiple of 4.0x, and an equity NPV of R2.3 billion at a 19% cost of equity. The organic counterfactual, no funded build, flat copper, destroys value, confirming that the capital programme is the source of the return. The copper price is the decisive variable: the equity IRR ranges from the low single digits at US$9,000/tonne to nearly 50% at US$15,000/tonne.

Three-case scenario analysis
Reducing the copper-price sensitivity to three underwriteable cases frames the decision cleanly. The downside case (US$9,000/tonne, below all current consensus forecasts) still returns capital, if modestly; the base case (US$12,000/tonne) delivers a ~32% equity IRR; the upside case (US$15,000/tonne, in line with some long-run forecasts) approaches 50%. The asymmetry is favourable: the low-cost, diversified position limits the downside while the structural copper deficit preserves substantial upside.

Two-dimensional sensitivity — copper price and exchange rate
Because TerraNova earns dollar-linked copper revenue against a largely rand cost base, the rand/dollar exchange rate is the second-order driver after the copper price, a weaker rand lifts rand revenue and returns. The grid below shows equity IRR across both variables simultaneously, isolating the combinations that most concern and most reward equity investors. A strong rand combined with weak copper is the genuine downside corner; a weak rand with firm copper is the upside.

The base case, US$12,000/tonne at R18.5/US$, sits mid-grid at approximately 34%. The exchange-rate effect is material but secondary: a full rand of depreciation (R18.5 to R19.5) adds roughly four percentage points to the IRR, against the fifteen-plus points that a US$1,500/tonne copper move contributes. The copper price remains the variable to underwrite.
Break-even copper price
Two break-even thresholds matter to lenders. The cash break-even, the copper price at which operating cash covers cash costs, sits near the modelled AISC of roughly US$1.7/lb (about US$3,800/tonne), far below any realistic price, reflecting the by-product-credited cost position. The full break-even for equity returns, the price at which the equity IRR meets the cost of equity, is approximately US$9,500–10,000/tonne on the modelled structure. Below that band the project still services debt but delivers sub-hurdle equity returns; above it, returns build quickly. The wide margin between the cash break-even and the price band is the quantitative expression of the mine’s resilience.
Indicative covenant package
The plan is structured to sit comfortably within a conventional project-finance covenant package, with the ramp-year tightness managed through reserves and a principal grace period.

Valuation and exit
The base case applies a 5.0x EV/EBITDA exit multiple to Year-5 EBITDA of R3.41 billion, implying an enterprise value of approximately R17.1 billion and equity value of roughly R13.1 billion after net debt and the rehabilitation provision. A 5.0x multiple is conservative for a diversified, low-cost, long-life producer with battery-minerals optionality, mid-cycle copper producers frequently trade at 5–7x, and strategic buyers pay more for integration and scarcity. Four credible exit routes support liquidity: a JSE listing (for which the governance framework is built), a strategic acquisition by a global mining house seeking copper and integration, a private-equity secondary, or participation in African copper consolidation. The battery-minerals platform (nickel sulphate) adds optionality increasingly valued by acquirers positioning for the energy transition.

Financing process and next steps
- Mandate & structuring of the R5.16bn senior facility with a DFI lead arranger and independent engineer.
- Bankable feasibility study and competent-person’s report to convert indicative parameters into declared reserves.
- Offtake & ESG term sheets and environmental/social action plans finalised as conditions precedent.
- Equity close of R3.44bn ahead of first drawdown, with staged, milestone-linked debt disbursement.
