How does this company make money?
Both mines sell copper at prices set by the London Metal Exchange — the global copper benchmark — adjusted up or down by negotiated treatment charges. Revenue is recorded when copper cathode or concentrate is physically delivered to an agreed port or customer facility. When the LME copper price rises, revenue rises on the same volume of metal; when it falls, revenue falls even if the mines produce exactly as planned.
What makes this company hard to replace?
Buyers of Candelaria's cathode are locked in by the 18-month requalification cycle required before any new supplier can be certified to meet the same electrical-grade copper specification. Switching means 18 months without a qualified source, which is not a practical option for wire rod manufacturers supplying telecommunications cable production. For Chapada concentrate, long-term offtake agreements with specific grade requirements mean fabricators cannot simply redirect to another supplier without renegotiating those contracts. Antofagasta port allocation slots also cannot be easily transferred between mining companies, adding a logistical friction to any attempt to substitute the supply.
What limits this company?
At Candelaria, the desalination plant can only supply as much water as Chilean regulators permit. When that allocation is tight — especially as lithium mining operations in the same water district compete for the same regulated supply — proven oxide ore reserves simply sit in the ground unprocessed. At Chapada, Brazilian environmental licences set the hard ceiling on expansion, and those licences have become much harder to obtain since court decisions following the Brumadinho dam disaster.
What does this company depend on?
Chilean mining permits and water rights are required for Candelaria to operate at all. Brazilian environmental licences govern what Chapada is allowed to do. Sulfuric acid must be supplied continuously for the heap leaching process at Candelaria. Antofagasta port access is needed to export copper cathode from Chile. Electrical grid connections in Minas Gerais keep Chapada's processing facilities running.
Who depends on this company?
Wire rod manufacturers in Asia rely on the specific electrical-grade copper cathode produced at Candelaria to make telecommunications cable. If Candelaria stopped delivering, those buyers would face an 18-month gap before a replacement supplier could meet the same specification. Construction pipe fabricators in North America schedule their production around consistent deliveries of copper concentrate from Chapada at specific grades — a licence suspension or processing interruption at Chapada would break those delivery commitments directly.
How does this company scale?
Running more ore through the existing flotation circuits and heap leach pads at both mines costs relatively little at the margin — the infrastructure is already built. What cannot be accelerated with money alone is finding and permitting new ore reserves in new places, because geological exploration takes time and regulatory approval in new jurisdictions follows its own timeline regardless of how much capital is available.
What external forces can significantly affect this company?
Chilean constitutional debates over mining royalties and water rights allocation directly threaten Candelaria's operating costs and water permit security. Brazilian environmental court decisions on tailings dam rules — shaped heavily by the Brumadinho disaster — control whether Chapada can expand. Chinese economic growth drives copper price swings on the London Metal Exchange, which determines how much revenue both mines generate and whether new development investment makes sense.
Where is this company structurally vulnerable?
If Chilean regulators cut the desalination plant's permitted water allocation — whether through a constitutional royalty reform, a water-rights rebalancing that favours lithium operations, or pressure from local community claims — heap leaching stops, oxide ore goes unprocessed, and the electrical-grade cathode supply to Asian wire rod buyers is severed. Those buyers then begin an 18-month requalification process with a substitute supplier, and the cathode market position that took years to build is lost.
