Mining Reform Law Takes Effect: New Environmental Framework, Military Zones

The New Framework

Ecuador's Mining Reform Law — approved by the National Assembly on February 26 and published in the Official Gazette on February 28 — entered into force on March 2, 2026. It represents the most comprehensive overhaul of Ecuador's mining regulatory framework since the 2009 Mining Law.

The reform addresses three structural bottlenecks that have constrained the sector: environmental permitting delays, illegal mining proliferation, and security risks at mining sites.

Environmental Authorization: Tiered System

The law's most consequential change replaces the single environmental impact license with a tiered environmental authorization system calibrated to project scale and risk:

Category	Project Type	Approval Body	Timeline (target)
Category I	Artisanal & small-scale (<300 MT/day)	Provincial environmental authority	30-60 days
Category II	Medium-scale (300-5,000 MT/day)	Ministry of Environment (MAATE)	90-120 days
Category III	Large-scale (>5,000 MT/day)	MAATE + interagency committee	6-9 months
Category IV	Strategic national projects	Cabinet-level approval	9-12 months

Under the previous regime, all mining projects required a full environmental impact study (EIA) processed through MAATE, with approval timelines averaging 18-24 months. The tiered system is designed to reduce permitting times by 40-60% for small and medium projects while maintaining rigorous oversight for large-scale operations.

Protected Mining Zones

The law creates a new legal concept of "Protected Mining Zones" (Zonas Mineras Protegidas) — designated areas of high mineral potential where:

• Military deployment is authorized for site security
• Illegal mining operations face expedited prosecution with penalties of 7-13 years imprisonment
• The armed forces can establish perimeters and checkpoints
• Environmental monitoring is conducted by joint civilian-military teams

The provision responds directly to the security crisis in mining regions, particularly in Zamora Chinchipe, El Oro, and Esmeraldas provinces, where illegal mining operations controlled by criminal organizations have proliferated. The government estimates 70,000-100,000 illegal miners operate nationally, generating an estimated $1.2 billion in annual unregulated output.

Artisanal Miner Formalization

The reform establishes a 12-month formalization window for artisanal and small-scale miners currently operating without permits:

• Simplified registration through ARCOM (Mining Regulation and Control Agency)
• Reduced environmental requirements (Category I authorization)
• Tax amnesty on previously undeclared mineral sales
• Technical assistance programs for improved extraction methods
• Access to formal markets and refining facilities

Miners who do not formalize within the 12-month window face reclassification as illegal operators subject to criminal prosecution.

The $14 Billion Pipeline

The reform is designed to unlock Ecuador's $14 billion mining investment pipeline:

Project	Operator	Mineral	Status	Est. Investment
Cascabel	SolGold	Copper-gold	Advancing to exploitation	$3-4B
Fruta del Norte	Lundin Gold	Gold	Producing (~310K oz/yr)	$2.7B (total to date)
Mirador	ECSA/Tongling	Copper	Producing	$1.8B
Warintza	Solaris Resources	Copper	Feasibility	$2-3B
La Plata	Adventus/Salazar	Copper-gold	Feasibility	$400M
Curipamba	Adventus/Salazar	Copper-gold	Exploitation permitting	$250-300M
Loma Larga	Dundee Precious Metals	Gold-silver	Suspended (litigation)	$400M

Mining exports reached $3 billion in 2024, up from $2.1 billion in 2023. The government has stated a target of $6 billion in annual mining exports by 2027 — a goal that depends on Cascabel reaching the exploitation phase and Warintza advancing through feasibility.

What to Watch

• Constitutional Court challenges — environmental groups and CONAIE have 90 days from publication to file challenges; the tiered authorization system and military deployment provisions are likely targets
• ARCOM implementation capacity — whether the agency can process the expected surge in formalization applications within the 12-month window
• Protected zone designations — which areas the government selects will signal prioritization between security enforcement and investment attraction
• SolGold's Cascabel decision — the single largest test of whether the reformed framework accelerates large-scale project timelines
• Illegal mining displacement — whether military enforcement pushes illegal operations into new areas rather than eliminating them
