Ecuador Signs First Open-Pit Gold Mine Contract: Cangrejos at $1.648B Investment, 26-Year Term

Contract Terms

Parameter	Value
Operator	Odin Mining Ecuador (subsidiary of CMOC Singapore)
Ultimate parent	CMOC Group (China)
Location	Between Santa Rosa and Atahualpa, El Oro province
Concession area	4,999 hectares
Contract term	26 years
Total investment	$1.648 billion
Projected government revenue	$6 billion (contract life)
Energy requirement	80 MW at peak production
Global deposit rank	13th largest undeveloped primary gold deposit

Employment

As of Q3 2025, the project supports 1,168 jobs — 292 direct positions and 876 indirect. This will scale significantly during construction and production ramp-up phases.

Strategic Significance

Cangrejos breaks a multi-year impasse in Ecuador's mining sector. The mining cadastre has been inactive since 2018, and flagship projects like Loma Larga (Azuay, copper-gold) remain suspended amid environmental and community opposition.

The contract was signed under outgoing Energy and Mines Minister Inés Manzano — one of the final major actions of her tenure.

Key distinctions:

• First open-pit gold mine in Ecuador's history (previous large-scale mining was underground)
• Chinese ownership via CMOC — aligns with broader Chinese investment patterns in Ecuadorian extractives (Mirador, Fruta del Norte financing)
• Coastal location (El Oro) avoids the highland water-table controversies that stalled Loma Larga

Energy Demand Implications

The mine's 80 MW peak requirement arrives during a period when Ecuador already faces a 900–1,000 MW generation deficit (see separate coverage). This creates a sequencing challenge: mining revenue depends on power supply that doesn't yet exist at sufficient capacity.

Revenue Context

Projected $6 billion in government revenue over 26 years represents:

• ~$231 million annually on average
• Approximately 0.8% of Ecuador's $30B annual government budget
• Meaningful but not transformational as a single project

However, Cangrejos establishes the regulatory precedent and operational track record needed to unblock other stalled concessions — which collectively represent tens of billions in potential investment.

What to Watch

• Mining cadastre reactivation. If Cangrejos proceeds without major controversy, political pressure to reopen the cadastre intensifies. Loma Larga, Cascabel, and other projects await.
• Energy supply for the mine. 80 MW must come from somewhere in a deficit grid. Watch for dedicated generation infrastructure (gas turbines, solar) as part of the project's development plan.
• Community and environmental opposition. El Oro has a mining history, but open-pit operations are a different scale of impact. Social license will be tested.
• Chinese investment concentration. CMOC joins Ecuador Copper (Mirador mine, Zamora-Chinchipe) in China's expanding Ecuadorian mining portfolio. Concentration risk in one origin country is a governance question.
