Decree 273 Overhauls Mining Royalties with 3-8% Sliding Scale

Decree Structure

Executive Decree 273, signed by President Daniel Noboa, implements the most significant reform to Ecuador's mining fiscal framework since the 2009 Mining Law. The decree replaces the previous flat-rate royalty system with a progressive sliding-scale mechanism designed to align state revenue capture with commodity price cycles.

Parameter	Previous Regime	Decree 273
Royalty structure	Flat rate (3-8% depending on mineral)	3-8% sliding scale
Price reference	Spot price at export	LME 3-year trailing average
Self-power requirement	None	100% (phased)
State take cap	No formal cap	50%
Concession registry	Frozen (since Jan 2018)	Reopened
Implementing agency	ARCOM	ARCOM

Sliding-Scale Royalty Mechanism

The new royalty rates are indexed to London Metal Exchange (LME) three-year trailing average prices, creating a counter-cyclical structure:

Copper Royalty Schedule

LME 3-Year Avg ($/lb)	Royalty Rate
Below $3.00	3.0%
$3.00-$3.50	4.0%
$3.50-$4.00	5.0%
$4.00-$4.50	6.0%
$4.50-$5.00	7.0%
Above $5.00	8.0%

Gold Royalty Schedule

LME 3-Year Avg ($/oz)	Royalty Rate
Below $1,800	3.0%
$1,800-$2,200	4.5%
$2,200-$2,600	5.5%
$2,600-$3,000	6.5%
Above $3,000	8.0%

The three-year trailing average smooths price volatility, preventing royalty rates from whipsawing with short-term price spikes. At current gold prices (~$2,950/oz), the three-year trailing average of approximately $2,450/oz would place gold operations in the 5.5% tier.

State Take Cap

Decree 273 introduces a formal 50% cap on total state take, defined as the combined burden of:

Component	Approximate Rate
Royalties	3-8% (sliding scale)
Corporate income tax	25%
Windfall tax	4-8% (on extraordinary profits)
Labor profit sharing	12%
Municipal taxes	1-2%
Total (uncapped)	45-55%
Effective cap	50%

The cap is designed to provide investment certainty by preventing the cumulative tax and royalty burden from exceeding half of gross mining revenue. When the combined burden exceeds 50%, windfall taxes are reduced first, followed by royalty adjustments.

100% Self-Power Mandate

One of the decree's most consequential provisions requires mining operations to generate 100% of their power requirements from self-owned or contracted generation:

Phase	Requirement	Deadline
Phase 1	50% self-generation	12 months from decree
Phase 2	75% self-generation	24 months
Phase 3	100% self-generation	36 months

This mandate directly addresses Ecuador's power crisis -- the 2024-2025 electricity rationing demonstrated that mining operations drawing from the national grid exacerbate supply constraints. Key implications:

• Capital costs increase by an estimated $50-100 million per major mining operation for generation infrastructure
• Solar, diesel, and natural gas are the most likely self-generation technologies
• Lundin Gold (Fruta del Norte) already operates significant self-generation capacity; CMOC's Mirador mine would require substantial investment
• Small-scale operators face disproportionate cost burdens that may force consolidation

Concession Registry Reopening

The decree reopens the metallic mineral concession registry, which has been frozen since January 2018 under the Moreno administration's moratorium on new concessions:

Registry Status	Period	Impact
Open	Pre-2018	Normal concession granting
Frozen	Jan 2018 - Decree 273	No new metallic concessions
Reopened	Decree 273 onward	New applications accepted

The eight-year freeze created a significant backlog of exploration interest, particularly for:

• Copper prospects in Imbabura and Azuay provinces
• Gold exploration in Zamora-Chinchipe and El Oro
• Rare earth elements in the eastern Cordillera

ARCOM (Agencia de Regulación y Control Minero) will administer the reopened registry under updated criteria that include environmental screening, community consultation requirements, and financial qualification standards.

Industry Reaction

The decree has received mixed but generally positive industry response:

• Lundin Gold described the sliding-scale royalty as "a step toward a more competitive and predictable fiscal framework"
• The Cámara de Minería del Ecuador endorsed the 50% state take cap as essential for attracting the $10+ billion in mining investment Ecuador seeks
• Environmental organizations criticized the concession registry reopening, arguing that environmental safeguards remain insufficient
• Small-scale miners expressed concern about the self-power mandate's capital requirements

Comparative Analysis

Country	Copper Royalty	State Take Cap	Self-Power Req.
Ecuador (Decree 273)	3-8% (sliding)	50%	100%
Chile	1-14% (sliding)	None	No
Peru	1-12% (sliding)	None	No
DRC	3.5% (flat)	None	No
Argentina	3% (flat, provincial)	None	No

Ecuador's 50% state take cap is unique among major mining jurisdictions and could become a competitive differentiator for attracting investment, particularly against Chile and Peru, where cumulative state takes can exceed 55-60% at high commodity prices.

What to Watch

• ARCOM's concession registry procedures -- the technical and environmental criteria for new applications will determine the pace of new exploration activity
• Self-power compliance timeline -- whether operating mines can meet the 12-month 50% threshold without production disruptions
• Llurimagua tender terms -- the first major application of Decree 273's royalty schedule to a greenfield project
• Lundin Gold's FdN royalty impact -- at current gold prices, the sliding scale may increase or decrease effective royalty rates versus the previous regime
• Constitutional challenges -- environmental and indigenous rights organizations may challenge the concession reopening in Ecuador's Constitutional Court
• Foreign investment response -- new concession applications in Q2-Q3 2026 will indicate international mining company confidence in the reformed framework
