Southern Copper: the Record Quarter Came From $6 Copper and $2.24/lb By-Product Credits While Output Fell 3.5%, and $198.76 Already Prices the Optimistic Case

The conclusion survives every reasonable decomposition convention. Benchmark metal prices contributed about $1.34bn before the drag from lower physical volumes; lower volumes removed roughly $0.17bn; mix, realization and other products contributed around $0.06bn. Copper itself added about $0.86bn of revenue, of which roughly $0.90bn came from price before the volume drag. The record quarter was overwhelmingly commodity-price driven.

Peru explains the volume weakness. Management attributed the decline to lower ore grades and lower recoveries at both Toquepala and Cuajone, not to water restrictions, a major maintenance shutdown or a new community blockade. The call singled out Cuajone as the largest component of the shortfall. At the same time, management raised its 2026 consolidated production guidance to about 917,000 tonnes, slightly above the earlier annual plan.

I regard the Peruvian weakness as a planned multi-year grade/sequencing trough rather than a structural impairment of the assets, but it is longer-lived than a one-quarter disruption. The February long-range plan already projected Peru falling from 411,100 tonnes in 2025 to 373,000 tonnes in 2026 before recovering to 390,100 in 2027 and 452,100 in 2028. That makes the Q2 decline consistent with the mine plan. The important qualification is that new-project tonnes are needed to offset this legacy-base decline; investors should not treat current reserve size as proof that annual production automatically grows.

The cost side of the quarter is equally revealing. SCCO's operating cash cost before by-product credits was $2.29/lb in Q2. After by-product credits it was only $0.05/lb. The difference, about $2.24/lb, came from by-product revenue. Gross operating cost was approximately unchanged from $2.31/lb in Q1; the extraordinary movement in the headline net cost came from the value of molybdenum, silver, zinc and other credits. Any peer comparison that puts SCCO's $0.05/lb beside another miner's gross cost is economically meaningless.

The portrait I end up with is a mature cash cow entering a commodity-driven re-rating while it funds a large organic project portfolio. SCCO is not a conventional secular-growth company. Its moat is physical: mineral endowment, low net cost, integrated processing and the ability to finance projects through the cycle. Its present earnings growth is mostly cyclical; its eventual production growth depends on executing projects in jurisdictions where permitting and community acceptance have historically taken much longer than engineering schedules suggested.

The market is trading a combination of three stories: structurally tighter long-run copper supply, exceptional near-term metal prices and the belief that SCCO's enormous reserve base can finally be converted into meaningful production growth. The first story has external support: the IEA's 2026 Critical Minerals Outlook sees copper demand increasing by about 7 million tonnes through 2040 and still sees an approximately 25% gap between expected 2035 mine supply from existing/announced projects and primary supply requirements under its stated-policy scenario. The second story is visible in Q2 prices. The third remains an execution question.

That is also the most important bull/bear disagreement. Bulls see one of the world's deepest listed copper resource inventories, low-cost operations and a pipeline capable of taking copper output from about 0.9–1.0 million tonnes today toward 1.6 million tonnes in 2035. Bears see a stock capitalising much of that distant output at a time when current earnings themselves are inflated by $6/lb copper and exceptionally rich silver/molybdenum credits. The two positions can both be factually correct; the valuation question is how much of each future has already been paid for.

The business story behind the ticker

Southern Copper did not begin as a venture-backed exploration company. It was incorporated in Delaware in 1952 and has conducted copper mining operations since 1960. Its Peruvian franchise was built around large Andean porphyry systems, chiefly Toquepala and Cuajone, tied to smelting and refining infrastructure at Ilo. The resulting system was vertically integrated decades before "energy transition" became an equity-market narrative.

The 1996 listing was similarly unlike a normal growth IPO. Primary filings establish that Southern Peru Copper was reorganised around large founding-shareholder blocks and that Cerro, Phelps Dodge and the interest associated with Grupo México/ASARCO were central to the ownership structure. The common stock has traded in New York and Lima since 1996. I did not find a sufficiently reliable primary-source reconstruction of the exact 1996 public-offering price and gross proceeds in the retrievable archive, so I do not manufacture an IPO number here. That is one of the explicit research blind spots below.

The decisive corporate transaction came in 2005, when Southern Copper acquired Minera México, consolidating the Mexican mining system with the Peruvian assets and creating essentially the company investors own today. The Mexican portfolio includes Buenavista, La Caridad and underground polymetallic assets, with associated smelting/refining infrastructure. From that point, the company ceased to be principally a Peruvian copper vehicle and became the integrated Peru-Mexico platform now controlled by Grupo México.

The next stage was brownfield expansion. Buenavista and Toquepala received major capital, and the company spent the late 2010s lifting production while pushing operating costs lower. Company presentations show EBITDA margins around 41% in 2016, 49% in 2017, 50% in 2018 and around 48% in 2019–20, illustrating that the assets remained highly profitable even before the 2021 and 2025–26 copper-price surges.

The latest stage began when Tía María moved from a repeatedly delayed option to actual construction. SCCO now describes more than $20.5bn of investment opportunities over the coming decade and a path to about 1.6 million tonnes of annual copper production by 2035. The step-change in the investment story is real, but the schedule is back-loaded: the February 2026 forecast remains around 0.9–1.0 million tonnes through 2028, reaches 1.15 million only in 2031, and does not move above 1.4 million until 2032.

The April 2026 leadership transition is the other historical break. Two dates are easy to conflate here: Oscar González Rocha died on April 7, while the SEC 8-K announcing his death was filed on April 13. He had led SCCO since 2004 and had sat on its board since 1999. The board first moved Leonardo Contreras Lerdo de Tejada into the succession process and appointed him permanent CEO on April 23, sixteen days after González Rocha's death.

The speed tells us something more important than the title change. Contreras was already an SCCO director, had held operating, commercial and financial roles inside Americas Mining and related companies, and is Germán Larrea's son-in-law. SCCO did not respond to a sudden 22-year CEO vacancy with an extended external search; it promoted from inside the controller's ecosystem. The process provides continuity and reduces key-person disruption, but it also underlines that SCCO is governed as part of the Grupo México system.

I find no evidence of a strategic reset since the succession. The July quarter retained the same production framework, Tía María priority, El Pilar progression and long-dated Peru/Mexico pipeline. SCCO also issued $1.25bn of 5.35% notes due 2036 for the benefit of its Peruvian branch, consistent with financing the existing investment program, not changing it. The post-succession disclosure pattern also remained CFO-heavy on the earnings call, with CEO Contreras present while Raul Jacob continued to carry much of the operational and financial explanation.

Financial vertical review

The last five complete years show how unusually profitable this asset base has been, and how strongly copper price flows through the accounts. Revenue moved from $10.93bn in 2021 to $13.42bn in 2025; operating income went from $6.07bn to $7.00bn; cash from operations totalled $19.84bn over the five-year period. Gross margin remained above 52% in every year and reached 60.1% in 2025.

Source: SCCO key financial data.

Cash conversion is strong. Aggregate operating cash flow over 2021–25 was about 1.23 times aggregate net income. After all reported capital expenditure, five-year free cash flow was approximately 91% of net income. That is unusually clean for a miner and argues against treating SCCO's accounting earnings as low-quality. The issue for valuation is the opposite: current earnings are high quality as cash, but the metal prices that generated them are cyclically high.

The balance sheet is stronger than a headline leverage screen implies. At June 30, 2026, cash was about $5.67bn and short-term investments about $1.67bn against approximately $7.99bn of debt; using the company's normal net-debt concept gives only about $0.66bn of net debt. Against roughly $12.63bn of stockholders' equity, that is about 5.3% net debt/equity. Even on the stricter convention that subtracts cash alone and ignores short-term investments, net debt/equity is only approximately 18%.

The long-run quality record is easier to confirm than any single screen field. Reconstructing 2016–25 from the older company presentations and current filings produces an average ROE of roughly 28%, and ten straight profitable years are supported by the annual results. Gross margin is the one field where SCCO is easy to misread. Screens showing a ten-year average gross margin near 44.6% are hard to reconcile with the company's own disclosure: the company-reported 2021–25 gross-margin average alone is 56.2%, while SCCO's 2016–20 EBITDA margins averaged roughly 47%, so a mid-40s ten-year figure would require early-period gross margins to sit below the EBITDA margin for several years. The likely explanation is a difference in data definition or line-item mapping, not a weaker business.

Capital-market narrative

SCCO's market history alternates between commodity discount and scarcity premium. The stock was historically valued as a high-quality cyclical miner; during the current copper-shortage narrative it is increasingly being valued as a scarce pure-play claim on long-duration copper reserves. The shift has a price consequence: the market now pays for the reserve optionality before most of the new tonnes arrive.

The 2026 move makes the point. SCCO closed at $144.32 on January 2 and $198.76 on September 4, a raw price increase of 37.7%. On an adjusted basis, January 2 was approximately $142.09 because of subsequent distributions, producing an adjusted gain of about 39.9%, close to the roughly 41% starting observation. The stock reached a 52-week high of $220.78 before retreating.

I would attribute roughly 70–85% of that 2026 re-rating to metal prices and the earnings revisions they created, with 15–30% to company-specific factors such as Tía María execution, project de-risking and distribution policy. This is an inference, not a daily regression. The evidence is unusually strong because copper output itself declined while earnings surged: the variable that changed most was price. The April CEO transition did not produce an observable break in strategy, while Tía María's physical progress and El Pilar approval improved longer-run confidence.

A fully auditable two-year daily event study is one area where I will not pretend to greater precision than the retrieved data allow. The historical feed exposed current and 2026 daily points reliably but did not give me a complete primary-source September 2024–September 2026 file suitable for a regression. The qualitative attribution across that two-year period remains clear: the biggest positive factor was copper's move from roughly the low-$4/lb area in 2024–25 to around $6/lb in H1 2026; Tía María's transition into construction added company-specific value; the succession itself was largely continuity.

Business model, moat, governance, and industry cycle

SCCO's business model is simple economically and complicated physically. It mines copper-bearing ore, processes it into concentrate or SX-EW cathode, smelts and refines part of the output, and monetises molybdenum, silver, zinc, gold and sulfuric acid along the way. In 2025 copper represented 74.8% of sales, molybdenum 10.5%, silver 7.3%, zinc 3.9% and other by-products 3.5%. Silver is the fastest-moving line: its share rose from 4.2% in 2023 to 5.1% in 2024 and 7.3% in 2025. Q2 2026 shifted toward 73% copper, 11% molybdenum and about 9% silver because the silver price more than doubled year on year.

Integration counts here. Owning mine, concentrator, smelter and refining assets does not eliminate commodity exposure, but it captures more processing economics and reduces reliance on third-party infrastructure. It also means sustaining capital is unavoidable: pits must be stripped, tailings handled, plant maintained, water systems supported and smelters periodically rebuilt. SCCO is a high-margin cash generator, but never a capital-light business.

Operating leverage is large because much of the mining cost base is tied to tonnes moved, installed processing capacity, labour, power and maintenance, and not to the copper price. SCCO's own trailing-12-month mine-cost breakdown showed maintenance at 25%, operating materials 18%, fuel 15%, labour 13%, power 11% and other items 18%. When copper moves from $4.50 to $6.00/lb, much of the incremental revenue therefore drops through EBITDA.

The same leverage works in reverse. At approximately 0.92 million tonnes of annual copper production, SCCO sells around two billion pounds of copper each year. A $1/lb change in realised copper price moves gross annual copper revenue by roughly $2bn before taxes, royalties, provisional-pricing effects and any operating response. This is why applying today's EPS to a normal equity multiple is the classic cyclical error.

The cost moat

SCCO's real moat is its resource-and-cost position, not brand, customer stickiness or technological lock-in. Customers do not pay SCCO a premium because copper cathode carries a Southern Copper brand. The advantage comes from owning very large ore bodies, established infrastructure and valuable by-products that allow the company to remain profitable at metal prices that would make many higher-cost development projects unattractive.

The company's own Wood Mackenzie-based 2025 cost-curve presentation places SCCO among the low-cost large producers on a C1-plus-sustaining-capex basis. That third-party dataset is shown through a company presentation, so I treat the exact rank cautiously, but it is consistent with SCCO's audited operating history. Net cash cost after by-product credits averaged $0.58/lb in 2025, compared with gross operating cash cost before credits of $2.17/lb.

The last eight quarters expose what is permanent and what is cyclical:

SCCO defines the first figure as its operating cash cost per pound of own-mined copper before by-product revenue credits; the second is the value of by-products and related credits allocated per copper pound; the third is the non-GAAP net result. Definitions are not standardised across miners.

The gross series tells a much less sensational story than the net series. Before credits, cost has drifted from roughly $2/lb toward $2.3/lb. After credits, it collapsed almost to zero because molybdenum and especially silver became exceptionally valuable. The operational moat is a combination of competitive gross costs and unusually rich co-product geology. Q2's $0.05/lb should not be capitalised as a permanent copper-production cost.

Governance is part of the valuation

Grupo México's 88.9% control is economically more important than the formal percentage of independent directors. The 2025 10-K states explicitly that the parent can determine the composition of the board, business direction, officer appointments, mergers, whether dividends are paid and in what amount, asset dispositions, debt financing and approval of capital projects. A minority SCCO shareholder owns a claim on an excellent group of mining assets whose major capital-allocation decisions remain controlled by another shareholder.

The 2026 board slate had eight directors. Six met the company's NYSE independence criteria, while Germán Larrea and Leonardo Contreras were the two clearly controller-linked directors. Formal independence should not be confused with electoral independence: an 88.9% shareholder can elect the board. Contreras' family relationship to Larrea reinforces that distinction.

There are genuine minority protections. Article Nine of the certificate requires material affiliate transactions to undergo independent-director review, and SCCO maintains “special independent director” provisions tied to the percentage of shares held outside the Grupo México group. The minimum requirement mathematically becomes modest when public ownership is only about 11%, although the present board has more independent directors than that minimum.

Related-party activity is material enough to monitor but not large enough, on current numbers, to explain SCCO's margins. In 2025 the company reported $473.0m of purchases from Grupo México affiliates and $99.4m of sales to them. The larger purchases included $207.0m from México Generadora de Energía, $71.5m from Asarco, $52.6m of construction services from México Compañía Constructora, $48.1m of rail freight from Ferrocarril Mexicano, $41.1m from Parque Eólico de Fenicias, $20.1m from Grupo México Servicios and $17.3m of engineering services.

The filing also states that Grupo México affiliates provide accounting, legal, tax, finance, treasury, HR, procurement, logistics, sales and administrative services. That creates economies of scale, but it means SCCO's stand-alone cost base cannot be viewed as entirely arm's length in the way it would be for an independent miner.

For a minority holder, the controller deserves a valuation discount even though the operating assets deserve a quality premium. There is effectively no conventional takeover-premium thesis while Grupo México retains 88.9%; dividends depend on a board the controller elects; the small free float reduces free-float-adjusted index weight and increases the possibility that marginal trading demand moves the price more than it would in a fully floated $168bn company. Those are economic inferences from the ownership structure, not allegations of abusive conduct.

Dividends: cash return versus stock-dividend optics

SCCO has returned a large share of cycle cash to shareholders, but the reported “dividends paid per share” series increasingly mixes cash with stock dividends. That distinction became important in 2024–25. The company's key-data page reports total 2024 and 2025 dividends of $4.60 and $6.60 per share, while cash-flow statements show actual cash distributions of about $1.64bn and $2.49bn. The difference comes largely from stock distributions valued for presentation purposes; a stock dividend does not take the same cash out of the company.

For payout analysis I use cash dividends:

Older figures are reconstructed from SCCO presentations; 2021–25 financials come from the company's current key-data page. FCF is operating cash flow less total capital expenditure.

Across those eight years, cash distributions absorbed roughly 76% of aggregate net income and about 83% of aggregate FCF. The board has distributed heavily through the cycle, occasionally paying more cash than that year's free cash flow and then pulling the cash dividend back. Management explicitly says the board assesses cash balances, expected operating cash flow, capital expenditure and financing needs when setting each quarterly dividend.

At a mid-cycle copper price, I would underwrite a cash payout around 55–65% of sustainable earnings rather than capitalise the recent “cash plus stock” headline. On normalized earnings around $5–6 per current share, that implies perhaps $3–4 of annual cash dividends. At $198.76 the corresponding yield is only about 1.5–2.0%. A low-copper-price year could cut that materially; SCCO's dividend history shows that the distribution is variable, not bond-like.

Copper's industry cycle

Copper is simultaneously a traditional macro commodity and a long-duration electrification input. Near-term balances still move with China, manufacturing, construction, inventories, mine disruptions and smelter economics; longer-term demand increasingly includes grids, renewables, electric vehicles and electricity-intensive digital infrastructure. The IEA expects copper to register the largest absolute demand increase among the critical minerals it tracks, adding about 7 million tonnes by 2040.

The supply argument is more convincing than a simple “AI needs copper” slogan. New mines require large up-front capital, years of environmental review, power and water infrastructure, and community agreements. Even after incorporating announced projects, the IEA estimates only about 75% of 2035 primary copper requirements are covered by expected mine supply in its base project pipeline.

Yet current scarcity should not be confused with a permanent spot shortage. ICSG's latest statistical table showed world refined production of about 14.40 million tonnes against usage of about 14.27 million tonnes in the relevant 2026 year-to-date period, an apparent surplus of roughly 131,000 tonnes. Long-term mine scarcity and short-term refined-metal surplus can coexist. That is precisely why a through-cycle valuation should sit below the 2026 spot price.

My through-cycle copper assumption is $4.50/lb, equivalent to about $9,921 per metric tonne using 2,204.62 lb per metric tonne. It is deliberately close to 2025's $4.51/lb LME average, far below Q2 2026's $6.04/lb, and further below the roughly $6.60/lb quoted on the September 4, 2026 base date. The assumption is higher than the approximate $3.30/lb copper price used in SCCO's reserve-economics framework because the IEA's longer-run supply gap suggests that new supply needs a higher incentive than the accounting reserve floor.

My conservative commodity case is $3.75/lb, or about $8,267/t. That is high enough for SCCO's existing operations to generate cash but low enough to challenge many greenfield projects and remove much of today's scarcity premium. My optimistic case is $5.75/lb, or about $12,677/t, below Q2's peak-like realised environment but high enough to sustain exceptional profitability. These are research assumptions, not forward-curve forecasts.

Current fundamentals, growth pipeline, and peer landscape

What actually happened in Peru

The Peruvian decline is best understood as mine-plan geology. Q2 output at the Peruvian mines fell 12% because Toquepala and Cuajone processed lower-grade material and experienced lower recoveries. Mexican output rose 3.2%, which is why the consolidated fall was only 3.5%. H1 output was also below the prior year.

A social or infrastructure interruption would be a different problem entirely. There was no disclosed Q2 shutdown explaining the loss. Management's own pre-quarter long-range production plan had already embedded a 9% reduction in Peruvian annual output from 411,100 tonnes in 2025 to 373,000 tonnes in 2026. That makes lower grades a known production-sequencing problem, not evidence that Cuajone or Toquepala have suddenly become impaired.

The structural element is that grades cannot be “cost-cut” back upward. SCCO must mine the ore sequence it has. The temporary element is that its reserve base is long-lived and the consolidated portfolio has projects that can offset that decline. I therefore expect base-mine volumes to remain lumpy through 2028 rather than assume a smooth rebound in Peru.

Reconciling Tía María with the 2028 target

The apparently inconsistent 2028 numbers reconcile because SCCO is explicitly forecasting legacy-mine decline beneath Tía María's new tonnes. The February production plan was 911,400 tonnes for 2026, 910,000 for 2027 and 970,300 for 2028. It broke 2028 into 452,100 tonnes from Peru and 518,200 tonnes from Mexico.

Tía María is designed for 120,000 tonnes per year. If it is fully ramped in 2028, subtracting those tonnes from the 970,300-tonne group forecast leaves about 850,300 tonnes from the pre-existing system. That is roughly 61,000 tonnes below the February 2026 group plan of 911,400 tonnes. The small apparent increase from annualising Q2's 230,662 tonnes (922,648 tonnes) to the 970,300-tonne 2028 target does not mean Tía María somehow adds only 47,000 tonnes. It means roughly half of Tía María's 120,000 tonnes are being used economically to replace declining grades elsewhere in the portfolio.

Management subsequently raised 2026 guidance from the February 911,400-tonne plan to about 917,000 tonnes. That improves the current-year comparison but does not alter the basic reconciliation. A credible forecast must model legacy mines and new projects separately.

Tía María

Tía María has moved from permitting option to construction asset. At June 30, 2026, SCCO said it was 42% complete, had invested about $693m, had approximately $1.101bn committed and continued to target first production in the second half of 2027. The project is designed to produce 120,000 metric tonnes a year of SX-EW cathode at an estimated cash cost around $1.16/lb. The current total budget is about $1.8bn.

The legal-permitting picture and the social picture diverge. Peru has granted the construction authorisation necessary for current works, and SCCO is physically building the project. Peru's Ombudsman's social-conflict reports in January and March 2026 nevertheless continued to list Tía María as an active socio-environmental conflict, describing opposition among farmers, residents and local authorities in Islay because of environmental concerns. The Ombudsman traces the dispute through the rejected 2011 EIA, the 2014 EIA approval and later construction authorisation and protests.

Tía María holds legal permission and incomplete social licence at the same time. The company can point legitimately to construction progress, local hiring and the planned use of desalinated water; opponents can point equally legitimately to an unresolved conflict that remains on the Ombudsman's monitoring register. A valuation that assumes “permit granted = social risk gone” is too optimistic.

Two precedents outside Tía María belong in the same assessment, because both sit in SCCO's own filings and both involve assets it already operates. In February 2022 protesters blocked the Cuajone-Ilo railway and seized the Viña Blanca reservoir facilities, cutting off water to part of the Cuajone mining camp until Peru declared a state of emergency in Moquegua that April; the 2025 10-K records that meetings held with community representatives between 2023 and 2024 produced no agreement, and that new representatives appointed in January 2025 have been more willing to engage. In Mexico, the 2014 release of acidulated copper sulfate from Buenavista del Cobre into the Bacanuchi and Sonora rivers remains a live contingency more than a decade later: three collective actions are still pending, dozens of civil suits filed from 2015 onward continue, PROFEPA's dismissed criminal complaint was under appeal at December 31, 2025, and SEMARNAT filed a further criminal complaint in October 2023 alleging that remediation and compensation were incomplete, which the company says lacks merit. Peru is where the growth is, but the social-licence record is a two-country record, and the Mexican half is still being settled.

At my $4.50/lb mid-cycle copper price, 120,000 tonnes equals about 264.6 million pounds. Against the stated $1.16/lb cash cost, the project would generate roughly $884m of annual pre-tax mine-level cash margin before royalties, sustaining capital and other corporate charges. A rough after-tax sustainable cash flow of $450–550m supports a standalone current NPV of around $3.5–4.5bn after remaining capital. A one-year delay would destroy roughly $0.35–0.5bn of present value plus any cost escalation, or only about $0.40–0.60 per SCCO share. The larger stock-market risk is the read-through: another Tía María delay would cause investors to apply a lower probability to Los Chancas and Michiquillay as well.

The rest of the pipeline

Project data combine the February 2026 company presentation with the newer July Q2 disclosure.

El Pilar provides a useful warning about using old decks. SCCO's February presentation carried a roughly $310m figure; the July disclosure updated the estimate to $551m, an increase of about 78%. The company did not describe this simply as a realised construction overrun, so I treat it as an updated scope/cost estimate rather than label it an overrun, but the revision illustrates the inflation risk embedded in decade-long mine plans.

Los Chancas has a different problem: SCCO says illegal mining activity continues to interfere with progress despite government enforcement. The project carries 130,000 tonnes of annual copper capacity in the company's plans, so a prolonged access conflict matters far more to post-2030 growth than a few quarters of grade variation at Cuajone.

Michiquillay is the largest of the announced Peruvian growth projects by designed annual copper output. SCCO cites approximately 2.288 billion tonnes of inferred mineral resources at around 0.43% copper and a planned 225,000 tonnes of annual copper output, but the start date is around 2032. At a 2026 base date, that means investors are paying today for cash flows that begin six years in the future and remain exposed to study, permitting, community and construction risk.

El Arco is geologically large but infrastructure-constrained. SCCO's Q2 disclosure says initiation depends on obtaining a CFE grid interconnection. The earlier February deck placed it around 2030, but that date deserves less weight than the explicit infrastructure dependency disclosed later.

The consolidated production path is more useful than promotional project capacity. SCCO's February forecast goes from 956,300 tonnes in 2025 to 911,400 in 2026, 910,000 in 2027, 970,300 in 2028, 1.061 million in 2029, 1.006 million in 2030, 1.152 million in 2031, 1.476 million in 2032 and roughly 1.606 million in 2035. It is a credible mathematical reconciliation of legacy decline and project additions; whether the dates survive contact with permitting is the investment question.

The peer group

The natural public-market comparison is Freeport-McMoRan. FCX is a larger physical copper producer, with assets in the United States, Peru and Indonesia and sizeable gold by-products at Grasberg. FCX says it supplied approximately 7% of the world's mined copper in 2025. Unlike SCCO, FCX has no 89% controlling shareholder and carries a much larger effective free float, but it has much greater single-asset exposure to Grasberg's underground system and Indonesian political arrangements.

At the September 4 close, FCX traded around $72.73 with a market capitalisation of roughly $105bn and a trailing P/E around 31, versus SCCO's approximately $168bn and roughly 29x. The apparent multiple parity hides different earnings bases and cannot be read as proof that SCCO is cheap: both are being valued in a high-copper-price environment, and FCX's recent earnings have been influenced by Grasberg's disruption and restart profile.

SCCO's advantage against FCX is the combination of simpler geography, unusually long reserve optionality and better by-product-adjusted cost performance. FCX's advantages are a much broader shareholder base, North American growth options and less controller-related governance discount. The customer does not meaningfully choose one miner's cathode because of brand; the competition is for ore bodies, permits, capital, labour, water, energy and the ability to deliver pounds at the bottom half of the cost curve.

Antofagasta is the cleaner Chilean pure-play reference. SCCO's February deck, using Bloomberg consensus, showed both SCCO and Antofagasta at roughly 59% 2025 EBITDA margins, while SCCO's total debt/EBITDA was shown around 0.9x versus about 1.5x for Antofagasta. Those are market-consensus figures reproduced by SCCO, not my preferred primary-peer filings, so I use them only directionally.

BHP and Rio Tinto are useful cost-curve and capital-allocation benchmarks but poor pure valuation comparables because copper remains one part of diversified portfolios. SCCO's own peer slide showed lower 2025 EBITDA margins for BHP, Rio and FCX than for SCCO, but diversified mining economics make the headline margins only partially comparable.

Zijin Mining is conceptually important because its equity story is the opposite of SCCO's: growth through acquisitions and project accumulation rather than primarily monetising a huge incumbent reserve base. Zijin's disclosed copper costs span a portfolio of mines across several countries and several metals, and a like-for-like comparison against SCCO's own-mined unit cost would need mine-level detail I have not reproduced here. The contrast worth drawing is strategic rather than numerical: Zijin buys optionality, SCCO already owns it.

That methodological discipline matters for cash costs. FCX's “net cash cost” includes gold and molybdenum credits under its own methodology; Antofagasta's C1 definitions differ; SCCO's $0.05/lb is after enormous Q2 by-product credits. The more defensible cross-company conclusion is that SCCO sits toward the low end of the industry cost curve on a C1-plus-sustaining-capital basis, while the spectacular near-zero Q2 figure is not itself a durable peer advantage.

What the market is trading now

The real fundamental improvement is commodity realization and project advancement. The overheated part of the narrative is treating the two as one phenomenon. Q2 EPS rose because copper and by-products repriced; production did not. Tía María, in contrast, is an actual volume project but contributes no operating copper yet.

The market currently appears to capitalise a blend of $5-plus copper, low net cash costs, an aggressive dividend narrative and a high probability of delivering the growth pipeline. At $198.76, the stock is roughly 37.9 times 2025 reported EPS of $5.24 and its enterprise value is around 21.5 times 2025 EBITDA of $7.82bn. Using current annualised Q2 EBITDA compresses EV/EBITDA to around 14.8 times, showing exactly how much the valuation depends on retaining the 2026 commodity windfall.

The next reported quarter is expected in late October. Third-party calendars currently disagree by one day, putting the expected Q3 event around October 27–28, 2026; SCCO itself had not posted a formal Q3 call date in the materials captured for this report. I therefore use October 27–28 as an expected window rather than a company-confirmed date.

Valuation and margin of safety

The valuation starts with copper, not with a P/E ratio. My three commodity cases are $3.75/lb conservative, $4.50/lb through-cycle base and $5.75/lb optimistic. The Q2 2026 LME average of $6.04/lb is deliberately excluded from the base case.

The $4.50 base is supported by three pieces of evidence. First, it approximates 2025's realised market environment, when LME copper averaged $4.51/lb and SCCO still produced $7.82bn of EBITDA and $4.33bn of net income. Second, it remains well above SCCO's reserve-economics copper assumption, preserving profitability at established mines. Third, the IEA's 2035 supply-gap analysis argues that the industry's long-run equilibrium probably needs to remain above historical marginal operating cost to incentivise difficult new projects.

The $3.75 conservative case is not a disaster scenario. SCCO's gross operating cash cost around $2.2–2.3/lb and its by-products mean the company remains cash-generative there. It is instead the level at which the equity market is likely to stop paying a scarcity multiple for distant growth.

Cash-flow passthrough

Five-year operating cash flow was about $19.84bn against cumulative net income of about $16.17bn, a 1.23x conversion ratio. Full free cash flow after all capital expenditure was roughly 91% of net income. Earnings convert to cash well enough that there is no accounting-quality reason to discard them.

Maintenance versus growth capital requires estimation because SCCO does not publish a clean quarterly split. In 2016 management described roughly $500m as a long-term maintenance-capex level; by 2025 depreciation, depletion and amortisation had risen to about $868m. I use $0.85–1.0bn as a current sustaining/maintenance-capital proxy and treat the capital above that level as predominantly growth or major-project spending. This is my assumption, not company guidance.

On 2025 numbers, operating cash flow of $4.75bn less roughly $0.9bn of maintenance capital gives about $3.85bn of “owner earnings.” That is only around 11% below reported net income of $4.33bn, a small enough gap that reported earnings remain a fair proxy for owner earnings. Full FCF was lower, $3.43bn, because SCCO was already spending on growth.

At today's $167.82bn equity value, 2025 owner earnings imply a yield of only about 2.3%; full 2025 FCF implies about 2.0%. The headline trailing P/E looks less severe because H1 2026 captures $6/lb copper. A cycle-normalized owner-earnings yield is the more conservative measure.

Absolute valuation scenarios

I use an enterprise-value approach anchored in normalized EBITDA, then add an explicit discounted value for projects that do not yet contribute to EBITDA. This avoids capitalising current record earnings while still giving SCCO credit for the reserve pipeline. The project values are probability-weighted and already assume future growth capex, so growth capex is not deducted a second time from owner earnings.

This is valuation-scenario analysis within a research framework, not investment advice.

The multiples look high for mining because SCCO deserves some premium for reserve duration, cost position and low balance-sheet leverage. I refuse to use a conventional 7–8x “ordinary miner” multiple; doing so would produce an even lower value. I also refuse to use today's roughly 15x annualised-Q2 EBITDA multiple as the base, because Q2 EBITDA itself reflects the commodity peak.

The base value around $138 per share implies an equity value around $116bn. That is already a substantial franchise valuation: roughly 12.5x normalized EBITDA plus $15bn for unstarted projects. It does not require copper to fall back to old-cycle prices; it requires only that $6/lb stops being the permanent baseline.

The optimistic value around $212 requires persistent high copper, successful project execution and a premium valuation multiple. At $198.76, the stock is already pricing something close to this optimistic operating regime. That does not mean the stock must fall. It means a buyer has little room for one of the three inputs to fail.

Historical and peer valuation

Current trailing P/E is about 29.4x, while the price is roughly 38x 2025 EPS. The 52-week price itself is near the upper fifth of its low-to-high range. On normalized earnings, I would classify today's valuation as above the 80th percentile of a sensible through-cycle valuation range, though I do not claim a statistically calculated multi-decade percentile without a complete adjusted-multiple history.

Peer multiples do not rescue the argument. FCX also trades around 31x trailing earnings in the current copper environment. If an entire pure-play copper group capitalises elevated commodity earnings at elevated multiples, relative valuation can say two expensive assets are similarly expensive. Absolute cash generation remains the check.

SCCO does deserve a premium to many miners because of reserve optionality and cost structure. It simultaneously deserves a governance discount because 88.9% control removes much of the corporate-control optionality a public shareholder normally owns. Those two valuation forces partially offset each other.

What Tía María is worth if it slips

At the $4.50 base copper price, I estimate Tía María's standalone present value at approximately $3.5–4.5bn after remaining construction capital. That is about $4–5 per SCCO share. A one-year delay reduces that value by around $0.4–0.6 per share directly; a two-year delay is roughly $0.8–1.1 per share before cost escalation.

That direct number understates its signaling value. If Tía María slips because of a project-specific engineering issue, the valuation effect should remain fairly contained. If it slips because the social conflict again halts construction, the market should reduce the probability assigned to Los Chancas and Michiquillay as well. A broad Peru social-licence reset could remove several billion dollars of probability-weighted pipeline value, easily several dollars more per share. The Ombudsman's continued classification of Tía María as an active conflict is why I retain that discount despite 42% physical completion.

Expectation gap

The largest expectation embedded in SCCO is a conjunction, not the single bet that “copper stays strong.” It runs on high copper prices, unusually valuable by-products, no severe legacy-mine deterioration and sufficient permitting execution to turn the 2030s projects into production. The valuation becomes much less demanding if only one assumption is considered at a time; it becomes demanding when the market needs several to remain favourable simultaneously.

The next quarterly print will matter less for whether revenue sets another record than for four underlying variables: Peruvian grades and recoveries, the before-credit cash cost, Tía María's completion percentage and updated full-year production guidance. A quarter with $6/lb copper and flat volume can still produce spectacular EPS without improving intrinsic operating progress.

The most fragile base-case assumption is project probability, not copper itself. If the $15bn probability-weighted project contribution is cut to 70%, the base project NPV falls to $10.5bn. Holding the operating valuation constant reduces base equity value by approximately $5.30 per share, to about $133. If the cut reflects a broader permitting problem that also justifies lowering the operating multiple by one turn, the valuation falls closer to the low-$120s.

Margin-of-safety recheck

The current $198.76 price is more than twice the approximately $94 value in the conservative case. The margin of safety to that scenario is zero.

If earnings remain flat for three years and SCCO distributes roughly 60% of normalized earnings in cash, the investor earns only about a 1.5–2.0% annual cash yield at today's price before any change in valuation multiple. No capital appreciation follows from flat earnings unless the market pays an even higher multiple. On that test, there is no margin of safety at this buy price.

This is the classic “good company, bad price” configuration. Waiting has an opportunity cost: copper could stay above $5.50/lb, Tía María could start on time, and the stock could remain expensive for years. That opportunity cost is preferable to underwriting a 2% normalized FCF yield with Peru-project risk.

Margin-of-safety sufficiency verdict: none.

Risks, catalysts, and tracking dashboard

The largest permanent-loss risk is commodity normalisation. I assign it medium-to-high probability and high impact. If copper falls from the Q2 $6.04/lb environment toward $3.75–4.00 while silver and molybdenum also normalise, SCCO loses both copper revenue and by-product credits. EBITDA could fall from Q2's roughly $11.4bn annualised pace toward $6–7bn while the valuation multiple compresses at the same time. That double hit is the most plausible route to a 40–60% equity drawdown without any mine failing operationally.

The second risk is that grade decline proves worse or longer than the current mine plan. Probability is medium; impact is medium. The observable indicators are Peru's tonnes, head grade/recovery commentary and the 2027–28 regional production forecast. The transmission mechanism runs from fewer pounds to higher fixed cost per pound and then lower EBITDA even if copper prices remain firm. The Q2 Peru decline is already the early warning variable.

Third is Peru project execution and social licence. Probability is medium and impact high over 3–5 years. The direct Tía María NPV hit from a one-year delay is manageable; the permanent-loss path comes if another social stoppage causes investors to lower probabilities across the wider Peruvian portfolio. The Ombudsman's 2026 conflict reports and the company's simultaneous construction progress should be watched together, not read selectively for whichever supports a preconceived bull or bear case.

Fourth is capex inflation. Probability is medium-high and impact medium. El Pilar's estimate moved from roughly $310m in the February deck to $551m in July. A similar percentage increase across several billion-dollar greenfield projects would destroy project NPV even if copper volume arrives on schedule. The indicator to watch is capex per incremental annual tonne, not headline project completion alone.

Fifth is controller risk. The probability of Grupo México losing control is low; the structural impact on minority valuation is medium. The risk is not that every related-party transaction is abusive. It is that capital allocation, dividend policy, board appointments and potential corporate actions are ultimately determined by an 88.9% shareholder whose portfolio interests are broader than SCCO. The company's own 10-K explicitly warns that parent financial obligations could create circumstances in which the parents seek loans, increased dividends or other funding from SCCO.

Sixth is valuation compression. Probability is high enough to matter and impact high. At approximately $168bn of equity value, SCCO is priced at roughly 38x 2025 EPS and a roughly 2% 2025 FCF yield. Even flawless operations can produce poor shareholder returns if copper merely reverts to $4.50 and the multiple follows.

Positive catalysts over the next twelve months are tangible: Tía María advancing materially beyond 42%, 2026 production meeting or exceeding the revised 917,000-tonne guidance despite Peru grades, El Pilar entering site preparation/construction without another major cost revision, and copper staying well above $5/lb. A better-than-expected Peru grade recovery would be especially valuable because it would show that the current earnings boom can be paired with physical growth.

Negative catalysts are the mirror image: Peru output remaining double-digit lower, Tía María construction interruption, El Pilar or another project receiving a second large capex reset, copper retreating toward $4–4.50, or the board cutting cash distributions as growth capex accelerates. SCCO's own forecast has annual capex rising from about $1.3bn in 2025 toward $1.9bn in 2026, $2.55bn in 2027 and more than $3.6bn around 2030, so the tension between dividends and growth spending will become more visible.

Operational and project reference points come from SCCO's Q2 release, call and February project plan; the earnings date remains a third-party expected range rather than a company-announced event.

The dashboard deliberately tracks gross and net cash cost separately. Gross cost tells us whether the mines themselves are becoming more or less efficient; net cost tells us what by-product geology and market prices are doing to equity economics. Watching only the $0.05/lb number would miss a deterioration in the underlying copper operation.

Cross-synthesis, uncertainties, and sources

Vertically, SCCO has proven one capability beyond reasonable dispute: it can operate enormous, integrated copper systems through multiple commodity cycles while maintaining high margins and a conservative balance sheet. That capability comes from geology and infrastructure first, operating execution second, and capital structure third. The ten-year profitability record and five-year cash conversion are evidence of a durable operating franchise, not a one-cycle accident.

Its historical success nevertheless has a large cycle component. SCCO did not create the price of copper, molybdenum or silver. The 2021 records were produced during a sharp copper upswing; the 2025–26 records arrived as copper moved still higher and silver/molybdenum credits became exceptionally valuable. The company deserves credit for having the ore bodies and cost structure that turn those price moves into cash. It does not deserve to have peak prices silently embedded into a perpetual valuation.

Horizontally, SCCO's best feature is the combination of low-cost resource duration and an almost entirely organic growth pipeline. It does not need to buy expensive copper companies simply to maintain relevance. Against FCX, that gives SCCO less Indonesian concentration and a very deep future project inventory; against diversified miners it gives shareholders much purer copper exposure.

Its weakness is the conversion rate from resources to timely production. Tía María took years of conflict before becoming a construction project; Los Chancas still faces illegal-mining interference; Michiquillay is a 2032 proposition; El Arco has an electricity-interconnection condition. The company's 1.6-million-tonne 2035 ambition is geologically credible but institutionally unproven.

The 2028 reconciliation is particularly instructive. A casual reading says SCCO has 923,000 tonnes of Q2 annualised production and a 970,000-tonne 2028 target, so Tía María's 120,000 tonnes barely matter. The actual company plan says otherwise: legacy production is declining underneath the new mine. That tells investors what the reserve story really is. SCCO needs new projects partly to grow and partly to replace declining ore grades.

The market is most likely misjudging the source of today's earnings. The improvement looks operational when viewed through EBITDA and EPS; the physical data say it is mainly price. Q2 copper output fell, gross cash cost remained around $2.3/lb, and the extraordinary $0.05/lb net cost resulted from $2.24/lb of by-product credits. A continuation of record net income therefore requires either continued elevated metals or a future volume response that has not yet arrived.

The market may be underestimating a different positive factor: Tía María has crossed from paper to construction. Forty-two percent completion, $693m already invested and large equipment commitments make another indefinite postponement less likely than it was several years ago. Social licence remains incomplete, but sunk physical progress changes the probability distribution.

For the next twelve months, copper price, Peru grades and Tía María construction dominate. Over three years, the decisive variable becomes whether Tía María reaches design output and El Pilar enters production close to its updated budget. Over five years, Los Chancas, Michiquillay and El Arco determine whether SCCO deserves to remain a premium growth copper multiple or reverts to a very profitable but mature miner.

The controller creates the most unusual tension in the equity case. Grupo México control has contributed to strategic continuity and a willingness to fund assets over decades. It also means minorities do not own the normal optionality of a fully independent corporation. The chief executive succession illustrates both sides: SCCO lost a 22-year CEO unexpectedly and filled the job within sixteen days, avoiding strategic paralysis; the chosen successor was already inside the controller's network and is the chairman's son-in-law.

The dividend has the same dual character. SCCO has genuinely returned large amounts of cash, but the board can vary the payout, and the increasingly prominent stock dividends should not be confused with cash yield. In a $6/lb copper world the distribution can look enormous. At my $4.50 mid-cycle price, the sustainable cash yield on a $199 stock is much less compelling.

The current valuation is spending future success ahead of delivery. My base value of approximately $138 already assigns a 12.5x normalized EBITDA multiple and $15bn to unstarted growth projects. The current $198.76 requires something close to my optimistic $5.75/lb scenario. The stock can earn its way into that price, but it has little protection if copper normalises first.

Bull reasons

The first bull reason is SCCO's cost and reserve position: 2025 net cash cost after by-products was $0.58/lb, and its company-presented Wood Mackenzie cost curve places it among the low-cost large producers.

The second is external copper scarcity: the IEA still sees an approximately 25% shortfall between expected 2035 mine supply and primary requirements under its stated-policy framework despite recent project additions.

The third is that Tía María is 42% built rather than merely permitted, meaning the first 120,000 tonnes of major greenfield growth now carry materially higher execution probability than they did several years ago.

The fourth is balance-sheet capacity: SCCO had only about $0.66bn of net debt at June 30, 2026 after including short-term investments, leaving plenty of room to fund a multi-year capital program without balance-sheet distress.

The fifth is long-run organic scale: the company's disclosed plan rises from about 0.91 million tonnes in 2026 toward 1.61 million tonnes in 2035 without requiring a transformational acquisition.

Bear reasons

The first bear reason is that Q2's records arrived while copper production fell 3.5%; benchmark metal prices added approximately $1.34bn before the drag from lower volumes, against a total reconstructed revenue increase of $1.24bn.

The second is valuation: $198.76 is around 38x 2025 EPS and implies only about a 2% yield on 2025 full FCF, leaving little protection against commodity normalisation.

The third is that near-zero net cash cost is partly a by-product-price illusion; Q2 gross operating cash cost was still $2.29/lb while by-product credits reached $2.24/lb.

The fourth is project timing. Tía María still sits on Peru's active social-conflict register, Los Chancas faces illegal-mining interference, and El Arco depends on grid interconnection.

The fifth is governance. An 88.9% controller can determine board composition, dividends, major corporate transactions and capital-project decisions, limiting the control rights and takeover optionality of the public float.

Pre-mortem

The most plausible 50%-loss script begins with copper, not a mine disaster. By 2028, Chinese and global industrial demand weakens enough for copper to settle around $3.50–3.75/lb while silver and molybdenum also normalise. SCCO's annual EBITDA falls from the Q2-2026 annualised rate above $11bn toward $6bn, Tía María begins production but mainly replaces declining legacy tonnes, and investors stop capitalising 2031–35 projects at a scarcity premium. An equity value around $80–100 becomes plausible. From $198.76, the share price falls roughly 50–60% despite SCCO remaining profitable and solvent.

The second script is project-specific. Tía María encounters renewed community disruption in 2027, production slips into 2029, El Pilar receives another meaningful capex revision, and investors push Los Chancas/Michiquillay probabilities down. Copper remains a respectable $4.50–5.00/lb, so earnings do not collapse, but the market removes the growth premium and values SCCO closer to a mature miner. A multiple compression from the current normalized high-30s P/E toward the low-20s, combined with normalized EPS near $5–6, can also put the stock around $110–130.

Final research conclusion

Southern Copper is an unusually good copper company. It owns a large, integrated asset base, converts earnings to cash, carries little net leverage and has an organic project inventory that many peers would have to buy at a steep price. The Q2 record does not weaken that assessment. It changes what the record means: current profitability is running ahead of current physical production because commodity prices and by-product credits have done extraordinary work.

At $198.76, I think the market is paying today for much of the outcome that should belong to the optimistic scenario. My base value is around $138 and my optimistic value is around $212. The current price offers meaningful upside only if copper remains structurally high and project execution is good; a conventional mid-cycle outcome produces a poor prospective return. The quality of the company is not enough to compensate for the absence of a valuation cushion.

What would change my view is straightforward. A price decline toward the $70s without evidence of structural reserve impairment would make the risk/reward dramatically better. Alternatively, sustained $5.50-plus copper accompanied by actual volume growth, Tía María operating on schedule and visible de-risking of Los Chancas/Michiquillay would justify raising the normalized valuation rather than merely chasing higher spot earnings.

【Company-profile scores】

• Fundamental quality: high
• Growth: medium
• Moat: strong
• Financial soundness: strong
• Management credibility: medium
• Valuation attractiveness: low
• Risk level: high
• Suitable investor type: cyclical

【Investment rating】

• Rating: Watch
• One-line thesis: SCCO is a low-cost, reserve-rich copper franchise priced as if strong metal prices and successful project execution largely persist.

The rating is Watch rather than Avoid because the structural copper case is unusually strong and the optimistic valuation is close enough to today's price that a sustained shortage regime could validate it. It is not Cautious Buy because the base-case prospective return remains negative and the conservative case offers no margin of safety.

【Ideal Buy Price】60–75 USD

Basis: the top of this range is at least 20% below the approximately $94 conservative-scenario value. A purchase there would require confirming that the lower price came from commodity-cycle compression rather than a permanent impairment of SCCO's mines or licences.

Acceptable hold price: 117–159 USD. This is approximately ±15% around the $138 base-case value.

Clearly overvalued price: 235 USD and above. This is more than 10% above the approximately $212 optimistic value.

Current-price classification: outside the three bands. At $198.76, SCCO is above the acceptable-hold zone but below my formal clearly-overvalued threshold; economically, it is already close to optimistic-case value.

Whether to wait for a better price: yes. My preferred trigger is below $75 while copper's long-run supply case remains intact and there is no permanent operational impairment. The opportunity cost is substantial if copper stays above $5.50/lb and Tía María ramps on schedule; in that case SCCO may never revisit the ideal-buy zone.

Target holding horizon: 3–5 years.

Expected annualized return from $198.76 over approximately three years, including scenario cash dividends: about -20% in the conservative case, -9% in the base case and +5% in the optimistic case.

Max-loss risk: roughly 50–60% in the pre-mortem commodity-and-multiple reset, with a possible $80–100 share price if copper falls toward $3.50–3.75/lb, by-product credits normalise and the scarcity multiple disappears.

Reassessment triggers: Peru's annual production guidance below 360,000 tonnes; gross operating cash cost above $2.50/lb for two consecutive quarters; Tía María first production formally moving into 2028 or later; another greater-than-15% El Pilar capex revision; or sustained copper above $5.50/lb accompanied by consolidated production guidance above 1.0 million tonnes before 2029. The first four would lower value; the fifth would make the optimistic commodity regime more credible.

【Valuation Range】

• bear (conservative · ideal buy zone): [60, 75]

• bull (optimistic · above the clearly-overvalued line): [235, 260]

Research uncertainties

The first blind spot is the exact 1996 public-offering price and capital raised. Primary records confirm the 1996 reorganisation and NYSE/Lima listing, but the SEC archive does not surface an offering document from which both values can be verified. I have therefore left them unresolved instead of importing a secondary-source number.

The second is the Zijin cost comparison. Zijin's copper costs are disclosed across a multi-country, multi-metal portfolio, and I have not reproduced the mine-level detail a like-for-like comparison against SCCO's own-mined unit cost would require. The FCX comparison in this report is built entirely from FCX's own disclosure and is unaffected by that gap.

The third is exact maintenance capital. SCCO publishes total capex but does not provide a clean current sustaining/growth split. My $0.85–1.0bn maintenance-capex estimate is anchored in current depreciation and older management guidance; shifting maintenance capital by $200m changes annual owner earnings by the same amount and therefore moves a 20x owner-earnings valuation by roughly $4.7 per share.

The fourth is the two-year stock event study. Current and 2026 price points were verifiable, but a complete adjusted daily primary series from September 2024 was not available in the captured research set. So my 70–85% copper-price attribution is a fundamental attribution, not a statistically estimated return decomposition.

The fifth is long-dated project timing. SCCO's 2031–35 output plan is company guidance, not permitted capacity. Given Tía María's history, illegal mining at Los Chancas and El Arco's grid dependency, the appropriate valuation treatment is probability-weighting rather than taking the 1.606-million-tonne 2035 target at face value.
