What is Dominga

Dominga is a world-class mining project, located in the town La Higuera, in the northern side of the Coquimbo Region, and designed to the highest international standards. Its purpose is to produce strategic minerals iron concentrate and copper concentrate while protecting the environment, driving human development, and generating shared benefits with local communities.

With its Environmental Qualification Resolution (RCA) already approved, the project is moving forward with the steps required to begin construction.

Inspired by best practices in sustainable mining, Dominga will:

• use desalinated seawater, avoiding the extraction of continental sources
• promote the use of clean energy in its operations
• launch a Socio-environmental Research Center to protect biodiversity and enhance scientific understanding of the territory

This modern and collaborative vision aligns with the Ten Principles of the United Nations Global Compact, reaffirming Dominga’s commitment to socially inclusive and environmentally responsible sustainable development.

Mining tradition

Dominga is part of the mining legacy of Chile’s Norte Chico, an activity that has shaped the region’s identity, progress, and pride.

In the 19th century, this area played a leading role in Chile’s mining boom. In La Higuera, the El Tofo mine stood out for its significance and innovative spirit, pioneering South America’s first electric train among other technological milestones.

That same spirit inspired projects such as the country’s first railway line, connecting Copiapó and Caldera, which helped drive development across the north. Today, Dominga continues that legacy with a modern, responsible approach, advancing sustainable mining for the 21st century.

Production

Environmental and technological contribution
With over 67% iron and almost no impurities, the concentrate that Dominga will produce requires less energy to smelt, reduces emissions, and generates less slag. Its high grade is ideal for producing superior quality “green” steels.

From iron to low-carbon steel
The ore is mainly used in steel manufacturing, which is necessary for the construction of bridges, buildings, railways and renewable energy equipment. The global steel industry is moving towards electric furnaces, the use of green hydrogen and increased recycling to decarbonise its production. Thanks to its high grade and processing efficiency, Dominga iron is driving this transition towards increasingly cleaner steel.

  • Member of the UN Global Compact (since 2024), integrating its Ten Principles on human rights, labor, environment, and anti-corruption across all operations. Since 2025, it has also been part of the Executive Committee. As of 2025, it also serves on the Executive Committee.

  • Exclusive use of desalinated seawater, without chemical, returned with 95% dilution to maintain natural conditions.
  • Seawater intake 750 meters offdhore at 20 meters depth; discharge 720 meters from the coast at 4 meters depth, in areas of high dispersion.
  • Supply of 5 liters per second of desalinated water to the community of La Higuera.
  • Restitution of groundwater to the Los Choros aquifer.

  • Center for Applied Socio-environmental Research and Studies (CIESA) to safeguard biodiversity and generate knowledge about the territory.
  • Reforestation of more than 8,000 hectares of native flora and vegetation as ecological compensation.
  • Ongoing participatory monitoring with the community at every stage of the project (information from the “Environment” section of the original document).

  • Shipping route more than 20 km from the Humboldt Penguin National Reserve, with only one vessel per week.
  • Loading terminal located 30 km from the Reserve, compatible with aquaculture and artisanal fishing.
  • Low-moisture thickened tailings that favor compaction, located 40 km from the Humboldt Penguin National Reserve, behind a natural barrier, reducing risks.

Community

Partnerships

We work together with expert institutions, integrating knowledge and best practices to ensure a project that meets today’s challenges. These collaborations reflect our commitment to a modern and responsible mining operation, aligned with the highest technical and ethical standards focused on creating shared value with our partners and the local community.

Questions

What is Dominga?

It is an iron and copper concentrate mining project located in La Higuera, in Chile’s Coquimbo Region. It has been designed according to high technical, environmental, and social standards and already holds valid environmental approval.

What sets Dominga apart from other mining projects?

Dominga will use desalinated seawater, safer thickened tailings, clean energy, and it will establish a Socio-environmental Research Center. The entire design takes into account environmental protection and community participation.

Will Dominga affect marine biodiversity or the Humboldt Penguin Reserve?

No. The shipping terminal will be more than 30 km from the reserve. There will be maritime exclusion zones, a wildlife rescue center, and participatory environmental monitoring.

What benefits will the community of La Higuera receive?

Dominga will create 10,000 direct and 20,000 indirect jobs during the construction phase, with priority given to local hiring. It will also provide desalinated water for the commune, annual funding for community initiatives, and revitalize small-scale mining.

What sustainability commitments has Dominga made?

Dominga has been part of the United Nations Global Compact since 2024 and applies its principles on human rights, the environment, and anti-corruption across its management.

What minerals will it produce and what are they used for?

12 million tons per year of high-grade, low-impurity iron concentrate and 150,000 tons per year of copper concentrate, critical inputs for the energy transition and sustainable urban development.

What permits does the project have?

Dominga has an approved Environmental Qualification Resolution (RCA) and is processing more than 250 sectoral permits to begin construction.

When will construction begin?

The project is moving forward with permitting and planning. Once this stage is complete, construction will begin according to the established schedule.

Who oversees environmental compliance?

The Superintendence of the Environment (SMA) and the Environmental Assessment Service (SEA) monitor compliance. Dominga also promotes participatory monitoring with the community.

How is community development in La Higuera funded?

Through the Framework Agreement for Human, Environmental and Productive Development, which sets out annual resources, defined by the community itself, to finance local initiatives throughout the project’s lifespan.

Will Dominga use continental (inland) water?

No. Dominga will rely exclusively on desalinated seawater for its operations, without affecting continental water resources or competing with human or agricultural consumption.

Where will Dominga’s facilities be located?

The mine site will be located over 12 kilometers inland from the coast, along Route 5 North, in a semi-arid region with a long-standing mining tradition. The loading terminal will be built in Totoralillo Norte, a fishing cove that hosted the municipality’s first mining port in the 19th century, and it will be subject to strict environmental measures.

What is the role of the communities in the project?

The community actively participates in working groups, environmental monitoring, and the prioritization of social investment projects. Ongoing dialogue has been part of the process since its inception.
