Decree 273 rewrites the Reglamento General a la Ley de Minería — the implementing regulation under the 2009 Mining Code — rather than the Mining Code itself. That distinction matters: Decree 273 is a presidential-level instrument and can be modified by future executive decrees, whereas the companion Ley Orgánica para el Fortalecimiento de los Sectores Estratégicos de Minería y Energía (approved by the Asamblea Nacional 26 February 2026, in force 2 March 2026 on Registro Oficial publication) is a statutory anchor for the same policy direction.
Five operative changes:
1. Price-indexed royalty scale. The 3–8% range now slides on a trailing three-year LME reference price: 3% of gross revenue when the spot price is below the reference, 5% at the reference, 8% above. This replaces the static range under the 2009 framework and captures upside when commodity prices rally (a structural feature of the current copper/gold cycle).
2. 100% self-power mandate. All mining projects must source 100% of their electricity needs themselves — closing what the government characterised as an implicit grid subsidy. Estimated capex impact: USD 150–400 million per large copper-gold project, per Ecuador Brief / Chambers 2026.
3. Royalty-deduction differentiation. Gold and silver royalties are now computed on gross revenue without deductions, raising the effective state take. For other metals (copper, molybdenum, REE) the previous "effective net income" basis is preserved, with small/medium operators able to deduct benefits/refining/transport and large operators only refining/transport.
4. Exploration-phase tightening. Initial exploration period capped (4 years), exploitation application must be filed within 12 months of completing exploration, and concessions automatically extinguish if activities do not begin within the new deadlines. Stated target: compress overall permit-to-production cycle from ~8 years to 3.5–5 years.
5. Royalty allocation. 60% of royalties channelled through decentralised governments for social projects — split 45% provincial / 35% municipal / 20% parochial. Increases political salience of mining at the local level and creates a transmission channel that ties commodity-cycle revenues to local fiscal capacity.
ARCOM (Mining Regulation and Control Agency) is repositioned with expanded competencies covering not only oversight but also regulation, audit, surveillance, and contract administration — a centralisation of functions that previously sat across ARCOM, the Ministry of Energy and Mines, and ENAMI.
pipeline — Cascabel (SolGold), Cangrejos (CMOC), Warintza (Solaris), Curipamba (Adventus), Loma Larga (Dundee Precious Metals), La Plata (Lumina Gold), plus Codelco-ENAMI exploration JVs — now faces a higher state take in gold/silver economics and a hard self-power capex line. The price-indexed royalty trades upside capture for reduced downside protection: at sub-reference copper or gold prices the effective state take is actually lower than the prior fixed range.
Ley Orgánica that elevates strategic minerals + strategic energy to "national interest" status — Decree 273 is the operating rulebook; the law is the constitutional-level anchor against future executive reversal. The combination is what was invoked at the 4 February 2026 US Critical Minerals Ministerial in Washington where Ecuador was named a strategic minerals source for US supply-chain diversification.
(Chile lithium strategy 2023, Peru REINFO formalisation 2025, Colombia Resolución 1006 strategic minerals 2023, Argentina RIGI/Decreto 449/Decreto 563) where state participation rules and sliding fiscal regimes are converging on a price-indexed model designed to capture upside without choking off marginal projects.
and EcuaCorriente (Mirador) — already operating — benefit from the decree's non-retroactivity. Greenfield entrants face the full new regime.
Forces project-level captive generation (likely solar + diesel hybrid given Ecuador's irradiance profile and grid-reliability concerns), which compounds the capex line but reduces exposure to Ecuador's drought-driven hydro shortages of 2023–2024.
for non-LME materials (REE, molybdenum)? The decree mandates the formula but the specific reference benchmarks for non-LME metals remain to be specified by ARCOM in implementing rules.
operators or only to medium- and large-scale concessions? The decree's literal text is ambiguous and likely needs ARCOM interpretive ruling.
provisions are already under domestic challenge; if those are struck, does the constitutional anchor for Decree 273's fast-track regime weaken? Watch the Corte Constitucional docket in 2026 H2.
programme negotiation; the 60% earmark to subnational governments reduces flexibility on central-government discretionary spend. Whether IMF conditionality forces a rollback or carve-out is a watch item.
