How Ecuador Mining Regulations Work When the State Is Your Partner

A state company kept 100% of a copper concession in July 2025, and the state still had to pay. After an arbitration with Chile’s Codelco, Ecuador’s state miner ENAMI EP walked away with full control of the Llurimagua project, yet Ecuador and ENAMI were ordered to reimburse Codelco about US$25.4 million.

If you assumed state control removes risk from a project, Llurimagua says otherwise. It is the clearest lesson in how Ecuador mining regulations actually behave once a foreign partner, a public company and a contested concession meet.

The stakes are rising. Central Bank of Ecuador data shows mining exports reached US$1.007 billion through Q3 2025, up 31.5% on the same period of 2024. At the same time, the rules on who holds concessions, and what holding them costs, are shifting, with ENAMI EP sitting at the centre of that system.

This covers three things you need before taking any Ecuadorian mining exposure: what ENAMI can legally do, how its participation shapes project economics and diligence, and how Ecuador’s model compares with Chile, Peru, Bolivia, Mexico and Argentina.

What is ENAMI EP and what legal powers does it hold?

ENAMI EP (Empresa Nacional Minera) is Ecuador’s state mining company. It was created by Executive Decree No. 203, published on 14 January 2010, and its official portfolio describes it as the state’s executing arm for mining policy.

Executive Decree No. 203 is the instrument that formally created ENAMI EP, so any check on the company’s legal powers should start from its founding mandate rather than from later project announcements.

That sounds administrative. The legal foundations underneath it are anything but.

Constitutional and Mining Law basis

The first layer is the Constitution. Articles 313-317 and Article 408 establish that non-renewable resources, including mineral deposits, belong to the state, and that mining is a strategic sector where the state may act directly or through public, mixed or private entities.

Alongside ownership sit consultation rights. Article 57(7) gives Indigenous peoples the right to free, prior and informed consultation on resource projects affecting their lands, and Article 398 requires environmental consultation for decisions that may affect the environment.

The second layer is the Mining Law, published in Registro Oficial Supplement No. 517 on 29 January 2009, as amended. It recognises ENAMI as the state mining company and, under Article 21, gives it preferential access to mining areas and concessions.

What ENAMI can actually do

The third layer is ENAMI’s own operating mandate. Its September 2025 investment presentation states it may participate in all phases of mining, and lists first-refusal and first-option rights alongside partnership authority. In practice, that means ENAMI can:

• apply for and hold mining concessions
• exercise preferential access, first-option and first-refusal rights
• conduct geological exploration
• form alliances and partnerships with foreign state-owned or private miners
• develop, process and market minerals

Stack those layers together and you get an entity that is both a market participant and a gatekeeper. Any foreign project in Ecuador may touch ENAMI directly, as a partner, or indirectly, as a competitor for the same ground.

There is a ceiling, though. ENAMI’s powers operate inside the constitutional consultation and environmental limits, not above them.

Not a permitting shield Law firm analysis in Chambers, Mining 2026: Ecuador (27 January 2026), stresses that projects remain subject to constitutional consultation, environmental approvals and Constitutional Court review, regardless of state participation.

How participation works in practice: ENAMI across Ecuador’s major projects

Those powers look uniform on paper. Across the actual project map, they play out very differently.

The pattern is sharp. ENAMI dominates the exploration-stage portfolio, including Pegasus with its roughly 34,895 hectares across seven concessions, according to ENAMI’s July 2025 systematisation report.

The producing mines tell the opposite story. The Central Bank’s 18 February 2026 bulletin recorded US$285 million of industrial mining investment through Q3 2025, with Mirador at US$123 million and Fruta del Norte at US$84 million, and neither carries any ENAMI equity that research could identify.

Llurimagua: the clearest test case

Llurimagua was meant to be a partnership: ENAMI 51%, Codelco 49%. The joint venture was never formed, and Codelco launched arbitration in 2021.

The International Chamber of Commerce (ICC) award, announced in Attorney General Communiqué No. 007 on 11 July 2025, rejected most of Codelco’s claims and confirmed ENAMI’s ownership.

The award in numbers Ecuador and ENAMI were ordered to reimburse Codelco US$25.377 million plus interest. The government said the outcome avoided more than US$540 million in exposure, while Codelco reportedly invested about US$51.7 million.

ENAMI kept the asset; Ecuador kept a liability. Control and exposure turned out to be separate things.

Even the retained asset is stalled. ENAMI’s 2024 accountability report states that Llurimagua’s environmental licence was revoked and mining activity judicially suspended over consultation findings.

For you, the takeaway is that “ENAMI is involved” tells you very little. What matters is which instrument you actually hold: a concession, a commercial agreement, a reimbursement right or real equity.

What recent rule changes and risks mean for foreign investors

If Llurimagua shows the cost of ambiguity, Ecuador’s recent reforms look like an attempt to reduce it.

Fiscal and regulatory changes

The mining cadastre, the official register for granting concessions, had been effectively closed for years. Ecuador reopened registration for some small-scale and non-metallic activity in June 2025 and announced a phased broader reopening.

Holding ground now costs more. ARCOM Resolution ARCOM-ARCOM-2025-0028-R (27 June 2025) set annual fees from roughly 3% to 100% of the basic unified remuneration (Ecuador’s reference minimum wage) per hectare, depending on scale and phase, with artisanal mining excluded.

Then came Executive Decree No. 273, issued by President Daniel Noboa on 31 December 2025. Primicias, Corral & Rosales and AVL Abogados reported that it introduced a royalty formula with progressive price thresholds, and that gold and silver royalties are calculated on gross income without some deductions available to other minerals.

Chambers summarises the headline state take as 25% corporate income tax, royalties generally 3-8%, 12% profit participation and 15% VAT. Your actual burden depends on the contract, mineral and structure.

Where the risk concentrates

Clearer rules on tax do not settle the harder questions. A ministerial consultation manual was issued in March 2024, but Chambers reported that no comprehensive consultation law had been enacted as of January 2026.

The World Bank’s 2025 analysis flagged frequent leadership and rule changes and weak institutional coordination. Community opposition, arbitration exposure, carrying costs on stalled concessions, organised crime and illegal mining all sit on top of that.

Your diligence on ENAMI’s role should sit alongside a clear view of how Ecuador mining permits move through the 4-year initial, 4-year advanced and 2-year economic evaluation windows, because a state partner does not shorten those statutory clocks.

Geology versus policy In the Fraser Institute’s 2025 survey, Ecuador scored 52.88 on investment attractiveness (58th of 68) but just 42.19 on policy perception (59th of 68). Its geology ranks far better than its governance.

ENAMI can improve access and political alignment. It cannot protect you from judicial review, consultation or fiscal change, so test each separately:

1. What instrument do you hold: concession, agreement, reimbursement right or equity?
2. Where does the project stand on consultation and court review?
3. What are the annual carrying costs if permitting stalls?
4. Which royalty and tax terms apply to this mineral and contract?
5. What is your counterparty and dispute exposure if a partnership fails?

How does Ecuador’s state-participation model compare with its neighbours?

Those risks look different once you see Ecuador’s model as one design choice among several in the region.

Peru shows that private-led development does not escape trouble either: Las Bambas and Quellaveco have both faced social conflict and permitting risk. Argentina’s risk varies province by province, while Mexico intervenes only where it deems minerals strategic.

The Codelco dispute ties two of these models together directly. Chile’s operating champion tried to buy into Ecuador’s concession-holding model and found the two did not fit.

That leaves Ecuador between Chile and Peru. You get more state-anchored access than in Peru, but a partner with less operating capacity than Chile’s, so your leverage and risk depend on the specific ENAMI arrangement you negotiate.

Weighing state participation before you commit capital

ENAMI turns constitutional ownership into an operating and negotiating vehicle. That creates access to ground private applicants may struggle to reach, and uncertainty about what a partnership with the state actually delivers.

The core diligence question stays the same: do you hold a legally enforceable project interest, or only a commercial arrangement with ENAMI?

Investors weighing partnerships with state entities often lean on investment protection frameworks, and the Codelco dispute shows why the structure of those protections should be settled before capital is committed.

Three items deserve watching: whether Ecuador finally enacts consultation legislation, how far the phased cadastre reopening extends, and how the Llurimagua litigation resolves. Terms change, so verify current details against official sources such as enamiep.gob.ec and seek professional advice before acting.
