Rio2’s $241M Condestable copper mine deal: project economics for engineers

30 Second Briefing
Rio2 is buying a 99.1% interest in Peru’s Condestable underground copper mine from Southern Peaks Mining for a total transaction value of $241 million, including $180 million upfront and assumption of $24 million debt, funded via $65 million vendor debt and an upsized $120 million equity raise at C$2.22 per receipt. Condestable, 90 km south of Lima, has an 8,400 tpd plant producing clean concentrate with scope to lift underground capacity to 12,000 tpd and add open pits, targeting about 27,000 tpa copper-equivalent and $110–145 million annual cash flow over five years. Rio2 plans to use this cash to expand Condestable and its Fenix Gold project in Chile, with combined output expected at 180,000 oz gold-equivalent per year and a potential pathway to 380,000 oz with a Phase 2 expansion at Fenix.
Technical Brief
- Condestable’s existing plant runs at 8,400 tpd, with engineering headroom to 12,000 tpd underground.
- Mine has over 60 years of continuous underground production, indicating mature geotechnical and hydrogeological understanding.
- Current output is a “clean” copper concentrate with no smelter penalties, easing offtake and logistics planning.
- Open pit development is being evaluated alongside underground expansion, implying future combined UG–OP mine planning.
- Deferred consideration of $37 million is scheduled between 2027–2030, affecting medium-term capital allocation.
- Vendor debt of $65 million forms part of the consideration, effectively leveraging the asset’s existing cash flow.
- Equity financing was upsized from $100 million to $120 million due to demand, despite share price dropping ~5%.
- Copper-equivalent cash flow guidance is split: ~$110 million at consensus prices vs ~$145 million at spot over five years.
Our Take
For a Latin America-focused junior like Rio2, moving from a single-asset Chile gold story (Fenix Gold) into a 60‑year producing copper mine in Peru materially de-risks cash flow compared with the greenfield and restart-heavy copper items elsewhere in our mining database.
The structure of the Condestable deal – a mix of cash, shares and assumed debt with deferred payments out to 2027–2030 – mirrors several other copper financings in our coverage where buyers are stretching consideration to keep leverage manageable while still securing near-term cash flow.
With consensus cash flow estimates of around US$110 million per year from Condestable versus a roughly C$1 billion market capitalisation, Rio2 is positioning itself closer to the cash-generative mid-tier copper names we track, rather than the exploration-heavy juniors that dominate many of the 114 copper/gold keyword-matched pieces in our database.
