Your spreadsheet says the deal doesn’t make sense. The market just priced it at a 40% premium to NAV anyway.
Welcome to mining M&A in 2026, where $53 billion megadeals are getting done while your DCF model insists they’re irrational. Anglo American and Teck Resources just merged at valuations that would make your finance professor weep. Glencore and Rio Tinto are in preliminary talks. Coeur Mining bid $7 billion for New Gold.
Deal value for transactions over $500 million is up 45% year-over-year. Meanwhile, every valuation model built on 2022 assumptions is systematically mispricing every asset in the sector.
The disconnect isn’t random. Your model is broken in ten specific ways. And until you understand how P/NAV actually gets priced in 2026, you’re flying blind.
1. You’re Still Treating Greenfield Development as a Real Option
It’s not. Not anymore.
The average copper project now takes 16 years from discovery to first production. That’s not a planning horizon. That’s a career. The capital intensity has crossed into territory where only the majors can play, and even they’re sweating.
Which is why Anglo American-Teck projected $2.2 billion in EBITDA synergies: with nearly two-thirds coming from operational consolidation of their Chilean copper assets. They’re not buying reserves. They’re buying the ability to avoid building something new.
Your valuation model treats “build vs. buy” as equivalent paths to the same production profile. The market is pricing in a 30-40% premium for operating assets because greenfield development has become functionally impossible for most players.
2. Your Commodity Price Deck Is Already Obsolete
Copper at $4.50/lb made sense when you built that model in Q3 2025. Then China announced stimulus. Then India’s grid investment accelerated. Then the Escondida labor negotiations went sideways.
Spot copper is trading above $6/lb. Your three-year consensus forecast is $4.80. That $1.20 gap doesn’t disappear because your model says it should.
The energy transition isn’t a theme anymore. It’s demand infrastructure. Every percentage point of grid electrification adds copper intensity that wasn’t in anyone’s 2024 forecast. Your valuation is anchored to a world that no longer exists.
3. You’re Underpricing Jurisdictional Risk by 300 Basis Points
Your discount rate has Chile at 8%, Peru at 10%, DRC at 15%. Clean, simple, wrong.
Resource nationalism isn’t a toggle switch anymore. It’s a sliding scale that resets every election cycle. Indonesia just changed export licensing rules. Tanzania modified royalty structures. Zambia announced new windfall taxes.
The majors are paying 25-35% premiums for Tier 1 jurisdictions not because they’re overpaying, but because your model treats political risk as static when it’s actually dynamic and worsening.
Anglo American’s Chilean consolidation makes sense precisely because operating in one stable jurisdiction is worth more than your spreadsheet can capture. The real discount rate for new African copper? Closer to 18-20% in today’s market.
4. ESG Compliance Costs Aren’t in Your Capex Estimate
You budgeted $50 million for “environmental mitigation.” The project needs $180 million in water treatment infrastructure before a single permit gets approved.
Scope 3 emissions reporting. Tailings management upgrades. Community benefit agreements that actually pass social license scrutiny. These aren’t line items. They’re structural cost inflation that’s adding 15-25% to brownfield expansion capex and 30-40% to greenfield development.
Your NAV calculation is using 2019 capex intensity. The market is pricing 2026 reality. That gap is permanent.
5. You’re Ignoring the Synergy Multiplier
Traditional M&A analysis looks at cost synergies: consolidate processing, eliminate duplicate corporate functions, optimize logistics. Those are real. They’re also the baseline expectation now.
The Anglo-Teck deal pencils out because Quebrada Blanca and Collahuasi share infrastructure, power grids, and port access. That’s not just cost savings: it’s capability multiplication. Combined metallurgical expertise. Shared water rights. Joint infrastructure investment that neither could justify alone.
Your model captures $500 million in cost cuts. The market is pricing $2.2 billion in EBITDA synergies because it’s valuing the operational leverage you can’t quantify in your spreadsheet.
6. Permitting Timelines Have Doubled (And You Haven’t Adjusted)
Your project schedule shows 36 months from Final Investment Decision to production. The regulatory approval process in Chile is now taking 48-60 months. In Canada, add another year.
That’s not project delay risk. That’s the new baseline. Every month of additional timeline is lost production, higher finance costs, and inflation exposure you haven’t modeled.
The premium being paid for operating assets reflects the market pricing in how impossible it’s become to actually develop new production. You’re valuing future production at today’s NPV. The market is discounting it by the probability it never gets built.
7. Water and Power Infrastructure Aren’t Getting Cheaper
The Atacama is running dry. Every Chilean copper operation faces water scarcity constraints that weren’t binding constraints five years ago. Desalination infrastructure costs $800 million to $1.2 billion per project.
Power availability in key African jurisdictions is unreliable enough that mines are building captive generation. That’s not an operating cost: it’s unleveraged infrastructure capex that doesn’t appear in reserve reports.
Your valuation assumes water and power at marginal cost. Actual development requires building entire utility systems from scratch. The P/NAV premium reflects this infrastructure deficit.
8. You’re Using the Wrong Multiple for a Supply-Constrained Market
Gold remains the most active M&A commodity by transaction volume. Copper deals are commanding the highest premiums. Why? Because copper supply can’t keep pace with demand, and everyone knows it.
The 2026 copper deficit is projected at 800 kilotons. That’s not a rounding error. That’s a structural shortage that’s going to persist through 2030.
In a supply-constrained market, producing assets trade at replacement cost, not book value. Your P/NAV of 1.2x might make sense in oversupplied iron ore. In copper, anything below 1.5x is getting bid up immediately.
9. You’re Treating All Pounds of Copper as Equal
They’re not. Copper from a Tier 1 jurisdiction with 20 years of mine life and expansion optionality trades at a 40% premium to marginal production from a single-asset company in a challenging jurisdiction.
Your NAV calculation values reserves at metal price minus operating cost. The market is pricing in jurisdictional stability, infrastructure access, ESG compliance, community relations, and management capability.
The Anglo-Teck combination creates a copper powerhouse with assets in Chile and Canada: two of the three Tier 1 jurisdictions that actually matter. That consolidation is worth more than the sum of the underlying reserves.
10. You’re Not Pricing in the Scarcity Premium for Operating Assets
The denominator is shrinking. Major discoveries are down 60% over the past decade. Development timelines have doubled. Capital intensity has tripled.
Meanwhile, energy transition demand is accelerating. AI infrastructure is copper-intensive. Grid modernization requires copper that doesn’t exist yet.
Every major knows that buying production is cheaper, faster, and less risky than building it. That’s not a temporary premium. It’s structural repricing of what operating assets are worth in a world where new supply isn’t coming online fast enough.
Your model still treats M&A as tactical portfolio optimization. The market is pricing it as the only viable growth strategy left.
How P/NAV Actually Gets Priced Now
Strip out the academic valuation frameworks. The real pricing mechanism in 2026 looks like this:
Base NAV: What your engineers say the asset is worth using consensus commodity prices and disclosed reserves.
Jurisdictional multiplier: 0.7x for high-risk, 1.0x for emerging, 1.3x for Tier 1. This isn’t subtle.
Supply scarcity premium: Add 20-30% for copper, 15-25% for gold, based on how tight the market is.
Synergy value: If it consolidates regional operations or creates infrastructure leverage, add another 15-25%.
Greenfield avoidance premium: Operating assets command 30-40% premium over development projects with equivalent reserve profiles.
Strategic premium: If it’s a blocking move to prevent a competitor from building critical mass, add whatever it takes to win.
Run those multipliers and you get to the 1.4x-1.8x P/NAV range where most 2026 deals are actually trading. Your spreadsheet says that’s irrational. The market says that’s the new normal.
The companies paying these premiums aren’t overpaying. They’re pricing in a world where building new production has become prohibitively expensive, politically complex, and operationally uncertain. They’re buying certainty in an uncertain world.
Your valuation model is a relic of an era when new supply was abundant, permitting was predictable, and capital was patient. That era ended somewhere around 2022. The market adjusted. Your model hasn’t.
Which is why you keep calling deals overpriced while they keep getting done at valuations your spreadsheet can’t justify. The problem isn’t the deals. It’s the model.
Mining M&A in 2026 isn’t about finding undervalued assets. It’s about understanding which structural premiums are justified and which are speculative. The majors consolidating Tier 1 copper assets in Chile understand this. The mid-tiers paying 1.6x NAV for operating gold mines understand this.
Your finance committee, still arguing about WACC assumptions and terminal value calculations, does not.
