The El Seguro project holds a singular position within the Malargüe Western Mining District (MWMD). It was the first project to be activated on the ground, served as the spearhead of MWMD Phase I, and is now consolidated as the second most advanced project in the district. However, its main differentiating factor lies not only in its level of progress: El Seguro is developed by the state-owned company Impulsa Mendoza Sostenible S.A., making it the first concrete case to assess how far Mendoza can go in a mining exploration process led directly by the State.

In practice, El Seguro has operated as a pilot project for the Mendoza model. This initiative has served to test administrative, environmental, logistical and technical procedures that are expected to scale across the rest of the district’s portfolio. As a result, its evolution goes far beyond its individual scope: it sets the pace and, to a large extent, also defines the operational limits of the MWMD itself.
At present, the project is undergoing a key early-works phase, focused on the construction of the access road, a strategic piece of infrastructure required to enable logistics, facilitate oversight, and prepare the site for future drilling campaigns.
This progress was recently audited on site by Mendoza’s Mining Environmental Authority, composed of the Mining Directorate, the Environmental Management and Oversight Directorate, and the Mining Environmental Police (PAM). The inspection aimed to verify compliance with technical, environmental and safety requirements, related both to the installation of the camp and the opening of access roads. During the site visit, inspectors confirmed compliance with the Environmental Impact Declaration (DIA) and current mining regulations, within the framework of the permanent monitoring scheme applied by the province to MWMD projects.
From the provincial government, officials also emphasized that El Seguro forms part of Mendoza’s exploration strategy, guided by principles of sustainability, environmental control and institutional transparency.
Geology and drilling
From a geological standpoint, El Seguro is supported by three mining properties, known as Fausto, Gitana and Yeso, located in an area intersected by two major metallogenic belts. On one hand, the Jurassic Magmatic Arc, dominated by granitic intrusives and basaltic-andesitic volcanics, with structural control in the Río de las Damas and Tordillo formations. On the other, the Miocene–Pliocene Magmatic Arc, representing the southern extension of one of the world’s most significant copper provinces, associated with copper–gold porphyry systems.
This geological setting is central to the project’s relevance, as it places El Seguro within the same geological corridor that underpins Chile’s large-scale mining industry, providing strong technical backing to the province’s district development strategy.
The exploration program includes stages of prospecting, indirect exploration involving geophysical surveys, mapping and sampling, and direct exploration through drilling. For this latter phase, expected to follow completion of the access road, the project plans to deploy two reverse circulation (RC) rigs and three diamond drill (DDH) rigs, a standard configuration for advanced copper exploration campaigns.
From an operational perspective, the project envisions a significant deployment of infrastructure and equipment. This raises a key strategic question: whether the state-owned company will proceed independently with this advanced exploration phase, which requires a substantial capital injection, or alternatively, seek to negotiate the project or bring in partners to address this stage.
Strategic character
Beyond its technical complexity, El Seguro poses a structural question for Mendoza: how far can a state-owned company go in a mining exploration process. Impulsa Mendoza must demonstrate not only geological and operational capability, but also administrative efficiency, execution speed and budgetary discipline, within a business that is capital-intensive and high-risk.
This strategic character is no coincidence. El Seguro was acquired by Impulsa Mendoza from the Mendoza-based company Agaucu even before the concept of the Malargüe Western Mining District became public, almost simultaneously with the creation of Impulsa Mendoza itself. This timing turned El Seguro into the ideal asset on which to begin designing the district framework: an already available project, with technical background and state control, allowing authorities to structure a tool aimed at accelerating legislative processing for multiple projects while simultaneously generating a meaningful volume of exploration in southern Mendoza.
From this starting point, the MWMD was built as an operational instrument, designed to organize projects, standardize environmental criteria, and enable exploration campaigns at scale. While progress has not been as fast as initially expected by the provincial Executive, the process continues to consolidate: a second phase has already been approved, and a new package of initiatives is under evaluation, under a framework that seeks to gradually expand the exploration front in Malargüe.
Within this context, El Seguro retains its role as the district’s flagship project. Not only was it the first to be activated, but it continues to serve as a benchmark for measuring administrative timelines, execution of early works, and real deployment capacity in the field. Its evolution allows stakeholders to anticipate how far the district model can scale and how quickly it can be translated into drilled meters, concrete geological data, and the definition of new copper targets.
