Stars
Centinela Second Concentrator Project
Centinela Second Concentrator Project is Antofagasta Plc’s brownfield expansion to nearly double Centinela’s processing capacity by 2027, positioning it as a Star in the BCG matrix with high growth and market share.
By 2025 the project exited peak capital spend—total capex to date ~US$1.8bn of an estimated US$2.0bn—and remains on schedule and on budget despite heavy cash burn typical of Stars.
Operational from 2027, it is forecast to add ~170,000 tpa copper-equivalent, lifting Centinela’s output ~45% and securing leading exposure to the green-copper market driven by electrification demand.
Los Pelambres Expansion Phase 1
Los Pelambres Expansion Phase 1 boosted ore throughput to ~170 ktpd by end-2025, adding ~150 ktpa copper equivalent and cutting freshwater use by ~60% via the new 100 Mm3/year desalination plant commissioned in 2024.
As a high-market-share star in Antofagasta plc’s portfolio, it captured surging copper demand—spot copper averaging ~US$9,000/t in 2025—while still needing operational support to reach full nameplate capacity (target ~200 ktpd).
As the company’s flagship asset, steady ramp-up and improved water resilience are set to drive free cash flow growth, positioning Phase 1 to transition into a dominant Cash Cow once nameplate output and steady copper prices persist.
Molybdenum By-Product Division
Antofagasta’s molybdenum by-product saw a 48% y/y jump in 2025, with output rising to ~35,000 tonnes thanks to higher grades and improved recovery at Los Pelambres and Centinela.
Demand is high for molybdenum in high-strength alloys and green energy (wind, EVs), placing this division in the Stars quadrant with strong competitive positioning and premium pricing.
Record 2025 prices boosted EBITDA contribution materially; the unit now funds operations but needs capex — an estimated $60–80m for processing upgrades to sustain growth.
Gold By-Product Sales
Gold production reached 211,300 ounces in 2025, up 13%, delivering by-product credits that helped Antofagasta cut net cash costs to a five-year low (approx. $0.90–1.10 per pound copper equivalent in 2025).
High gold prices and safe-haven demand make this segment a Star in the BCG matrix, capturing significant value from existing ore bodies and boosting margins.
Sustaining growth needs ongoing capital for recovery-circuit upgrades; reinvestment rates should match ~10–15% of segment cashflow to retain the edge.
- 2025 gold: 211,300 oz (+13%)
- Net cash costs: five-year low (2025)
- Star: high growth × high market share
- Capex signal: ~10–15% of cashflow for recovery upgrades
Encuentro Sulphides Pit Development
Approved in mid-2025 with a $1 billion capex, Encuentro Sulphides Pit Development targets higher-grade ore to feed the new Centinela concentrator and supports Antofagasta’s medium-term goal of stabilizing copper output at ~650–700 ktpa by 2028.
As a first-to-market push into deeper sulphide reserves, it is consuming large cash for stripping—estimated $200–300 million in 2025–26—but could supply ~15–20% of group concentrate by 2030, making it a clear BCG Star.
Here’s the quick math: $1bn capex, $250m near-term stripping, ~15–20% future output share; payback and IRR depend on received concentrate grades and LME copper price assumptions.
- Approved mid-2025; capex $1,000,000,000
- Near-term stripping cash ~ $200–300m (2025–26)
- Expected contribution ~15–20% of group concentrate by 2030
- Supports group target ~650–700 ktpa copper by 2028
High‑growth mines to add ~320 ktpa Cu-e by 2027–30; moly +48%, gold 211k oz (2025)
Centinela 2Q (capex ~US$2.0bn; to-date US$1.8bn) and Los Pelambres Ph1 (170 ktpd; +150 ktpa Cu-e) are Stars—high growth, leading share—forecast to add ~320 ktpa Cu-e by 2027–30; Encuentro (US$1.0bn; stripping US$200–300m) supports 650–700 ktpa group target; moly +48% (2025: ~35,000 t), gold 211,300 oz (2025).
| Asset | Capex | 2025 output | ΔCu-e |
|---|---|---|---|
| Centinela 2Q | US$2.0bn (US$1.8bn spent) | — | +170 ktpa |
| Los Pelambres Ph1 | — | 170 ktpd | +150 ktpa |
| Encuentro | US$1.0bn | — | 15–20% group by 2030 |

Cash Cows
Los Pelambres Core Operations
Los Pelambres, Antofagasta’s premier asset with 25+ years of operation, sits in a mature, high-market-share position and generated the bulk of Group cash in 2025.
In 2025 Los Pelambres underpinned Antofagasta’s record $5.2 billion EBITDA, supplying free cash flow to fund capital-intensive expansions like Centinela JV and Mantoverde upgrades.
With low relative growth versus new projects, Los Pelambres functions as a cash cow: steady output is milked to pay dividends, service $6.5+ billion net debt and finance capex.
Centinela Concentrates (Existing)
Centinela’s existing concentrator lines are mature assets that in 2025 delivered steady output of ~150 kt Cu equivalent and operating margins near 48%, reflecting stable throughput and cost control.
They operate in a low-growth, mature market where Antofagasta plc is a leader with integrated infrastructure and long-term offtake contracts supporting predictability.
Cash flow from Centinela—roughly US$420m free cash in 2025—was allocated to the 'Star' second concentrator project, illustrating the BCG cycle of funding growth from cash cows.
Antucoya Mine
Antucoya Mine is a mature, low-cost heap-leach copper operation producing cathodes with a dominant niche share; in 2025 it drove steady cash flow with ore grades ~0.45% Cu and recovery ~68%.
Operational efficiencies and higher realized copper prices (average LME-ref price ~$9,200/t in 2025) lifted EBITDA 19% year-on-year to an estimated $420m, with minimal growth capex.
It functions as a reliable liquidity source for Antofagasta, needing only sustaining capex (~$40–50m/year) to keep current capacity and dividend support.
Zaldívar Mine (Existing Life)
Zaldívar remains a steady cash generator for Antofagasta, delivering ~180 kt Cu cathode in 2024 and supporting Group free cash flow with roughly $450–500m annual EBITDA pre-2025 adjustments.
In 2025 the company settled water extraction claims, clearing regulatory risk and enabling continued steady production; established processes and ~25% cathode market share cement its Cash Cow status.
- 2024 output: ~180 kt Cu cathode
- Pre-2025 EBITDA contribution: ~$450–500m
- 2025: water-claim settlement removed major regulatory overhang
- Cathode market share: ~25%
Dividend Distribution Capacity
Bolstered by a 106% rise in underlying earnings in 2025, Antofagasta’s dividend distribution capacity cements its Cash Cow status, with mature copper operations generating large free cash flows and liquidity.
The board recommended a final dividend reflecting a 50% payout ratio, funded by 2025 operating cash flow of roughly $3.2 billion and ending cash reserves near $2.1 billion, sustaining steady returns.
- 106% underlying earnings growth (2025)
- 50% recommended payout ratio (final dividend)
- Operating cash flow ≈ $3.2bn (2025)
- Ending cash ≈ $2.1bn (2025)
Antofagasta's four mines generated ~$3.2bn FCF in 2025, funding debt, dividends and projects
Los Pelambres, Centinela, Antucoya and Zaldívar acted as Antofagasta cash cows in 2025, jointly driving ~US$3.2bn operating cash flow, funding $6.5bn net debt service, sustaining a 50% recommended payout and financing star projects.
| Asset | 2025 FCF (US$m) | Output (kt Cu eq) | EBITDA (US$m) |
|---|---|---|---|
| Los Pelambres | ~1,200 | — | ~1,800 |
| Centinela | 420 | 150 | — |
| Antucoya | ~120 | — | 420 |
| Zaldívar | ~350 | 180 | 450–500 |

Dogs
Centinela Cathodes Segment
Centinela cathodes saw production fall 35% in 2025 to ~48,000 t due to lower grades and 12% lower ore throughput, marking it a low-growth, shrinking-share unit.
With EBITDA margins turning negative in H1 2025 and cash costs above $8,500/t, the segment is a cash trap struggling to break even as the firm pivots to sulphide concentrates.
Given 2025 CAPEX cutbacks and Antofagasta’s focus on higher-margin sulphides, Centinela cathodes are prime for phase-out or minimal sustainment.
Legacy Diesel Transport Fleet
Legacy diesel rail and truck units in Antofagasta's Transport Division face <1% annual volume growth and rising CO2 compliance costs, with maintenance eating ~18% of transport opex vs 6% for electrified units.
Regulatory fines and carbon pricing lifted projected lifetime costs ~30% higher than hydrogen/electric peers, so Antofagasta is reallocating capital to H2/electric projects, sidelining these assets as Dogs in an ESG market.
Unproductive Exploration Tenements
Antofagasta holds early-stage exploration tenements that have delivered minimal results or hit permitting blocks, tying up about 0.5–1.2% of group capital expenditure and roughly 3–5% of exploration staff time in 2024, so they behave as Dogs in the BCG matrix.
The company routinely divests or spins off these non-core parcels—Antofagasta sold 2 small tenement packages in 2023 for ~$12m—to reallocate funds toward higher-potential Question Marks and Stars with clear development pathways.
Discontinued International Ventures
Antofagasta’s discontinued international ventures, notably stalled North American projects, still carry around $12–18m in annual administrative costs as of 2025, despite no operational output; these units meet BCG Dogs criteria—low market share and low growth—and have not reached scale to justify new capital.
Strategic reviews in 2024–2025 flagged these assets for divestiture or write-downs; management cited potential impairments up to $40–60m to clean the balance sheet if no buyers emerge.
- Annual admin expense: $12–18m
- Potential impairment range: $40–60m
- Status: no production, stalled development
- Recommendation: divest or full write-down
High-Cost Peripheral Services
Certain internal service departments at Antofagasta, lagging the Competitiveness Programme, are classed as Dogs: inefficient, low-value units that drain resources without boosting copper market share.
Management targets $115 million in 2025 productivity savings to remove Dog traits from legacy processes, aligning headcount, outsourcing, and automation with 2024 baseline costs.
- Identify: legacy internal services
- Cost drain: share of G&A up ~2–3% of 2024 revenue
- 2025 aim: $115M savings
- Actions: headcount cuts, outsourcing, automation
Divest or Write-Down: Centinela & Legacy Assets Hit by Negative EBITDA, High Costs
Centinela cathodes, legacy transport, stalled tenements and discontinued ventures are Dogs: negative H1 2025 EBITDA, cash costs >$8,500/t, Centinela production -35% to ~48,000 t; transport maintenance ~18% opex; admin drain $12–18m pa; potential impairments $40–60m; 2025 CAPEX reallocated; recommendation: divest or write-down.
| Asset | 2025 key metric | Impact |
|---|---|---|
| Centinela cathodes | 48,000 t; EBITDA negative; $8,500/t cash cost | Phase-out |
| Transport (diesel) | Maintenance ~18% opex | Sidelined |
| Stalled tenements | 0.5–1.2% capex tie-up | Divest |
| Discontinued ventures | $12–18m admin; $40–60m impair | Write-down/divest |
Question Marks
Hydrogen Locomotive Pilot (FCAB)
Launched in 2025 as South America’s first hydrogen locomotive pilot (FCAB), the project sits in a high-growth green logistics market (global hydrogen transport market projected CAGR ~14% to 2030) but holds negligible market share and burns ~US$12–18m/year in R&D and pilot ops.
If tech and scaling prove viable, it could become a Star for Antofagasta’s Transport Division; failure would likely create an ongoing Dog burdening capital and EBITDA.
Cachorro Exploration Project
Cachorro Exploration Project got environmental approval in 2025 for seven years of exploration, opening a high-growth play in a new mineral district with potential for copper-gold resources; Antofagasta must now decide on aggressive spend.
Currently the project has 0% market share and 0 revenue while in evaluation; Antofagasta plans initial drilling and feasibility capex estimated at USD 40–70m over 2025–2027 to de-risk the asset.
If drilling confirms >0.5–1.0Mt contained copper equivalent and IRR >15% at long-run copper USD 3.50/lb, the Question Mark could become a Star; otherwise write-down risk rises.
Cuprochlor-T Patented Technology
Cuprochlor-T, Antofagasta’s patented low-capex leaching tech for primary sulphides sits in the BCG Matrix Question Marks quadrant: high-growth innovation but low market share given limited industrial use; pilot economics suggest <10% incremental operating cost and potential +15–25% mine life for typical porphyries.
Success hinges on imminent industrial-scale leach pad trials (Q3–Q4 2025); if successful, NPV upside could exceed $300–700m per large deposit, but failure would leave a high-risk, capital-allocation drag on the group.
Peru Exploration Portfolio
Antofagasta’s push into Peru targets high-growth copper belts where its 2024 estimated share is <5%, aiming to diversify beyond Chile and capture projects with >1Mt Cu equiv potential; these moves seek new reserve pipelines but raise capital needs and timeline risk.
These ventures are Question Marks: they demand large upfront spend (exploration + feasibility often >$100–200m per project), face Peru’s complex permitting and social risks, and lack guaranteed payback.
They are strategic bets—successful projects could become Stars (high market share, rapid growth) by 2030, or be divested if milestones (resource, IRR >10%, permits) aren’t met.
- Low current share in Peru: <5%
- Project capex range: $100–200m (exploration→feasibility)
- Target reserve scale: >1Mt Cu equiv
- Exit criteria: resource, IRR >10%, permits
Zaldívar Mine Life Extension (Post-2030)
While Zaldívar currently generates steady free cash flow as a Cash Cow, the proposed investments to extend mine life past 2030—new water sourcing and processing plants—are Question Marks due to high capex (estimated US$900–1,200m) and tight IRR sensitivity to copper prices and water permits.
These plans face intense environmental review (Chile water rights reform 2024–25) and regulatory uncertainty; Antofagasta must decide by 2026 to either invest to create a Star or manage a graceful exit.
- Capex estimate US$900–1,200m
- Decision deadline 2026
- Regulatory risk: water-rights reforms 2024–25
- IRR highly sensitive to spot copper
High‑risk $1.2–2.3bn 2025 bets: pilots, drilling & Zaldívar life‑extension—make or break 2026
Question Marks: hydrogen loco pilot, Cachorro, Cuprochlor-T, Peru plays, Zaldívar life‑extension—high growth but low share; combined 2025 spend need ~US$1.2–2.3bn (pilots + exploration + trials + Zaldívar capex). Key milestones: 2025–2027 drilling (Cachorro), Q3–Q4 2025 leach trials, 2026 Zaldívar decision; success could convert to Stars, failure => write-downs.
| Project | 2025–27 spend (US$m) | Milestone | Upside |
|---|---|---|---|
| Hydrogen loco | 12–18/yr | scale/pilot | green logistics Star |
| Cachorro | 40–70 | drilling 2025–27 | >0.5–1Mt Cu equiv |
| Cuprochlor-T | pilot 10–30 | Q3–Q4 2025 | NPV +300–700m |
| Peru plays | 100–200/pp | permits, drill | reserve pipeline |
| Zaldívar | 900–1,200 | 2026 decision | extend life past 2030 |
