With the return of metal mining projects, the province once again faces a key technical challenge: managing mining activities from design through closure, under international standards and with long-term continuity.

Mendoza is not only debating individual mining projects. At a deeper level, the current discussion reveals something more structural: the province is relearning how to manage long-term mining development after more than two decades without large-scale metal mining activity and without sustained accumulation of local technical expertise. This perspective emerges clearly in a conversation with Alejandro Demonte, a civil engineer and general manager of Knight Piésold, an international engineering firm based in Mendoza that operates across the full mining value chain, from exploration through closure.
From his experience, Demonte emphasizes that mining in Argentina is fundamentally a provincial decision. “Mining is a provincial reality rather than a national one; the main drivers of mining development are the governors,” he explains. This framing helps clarify why Mendoza’s process has its own pace, tensions, and complexities. The issue is not simply whether projects are approved or rejected, but whether the province can rebuild the institutional and technical capacity required to manage them consistently over time.
One area where this distinction becomes particularly evident is the interpretation of the Environmental Impact Assessment (EIA). In public debate, the EIA is often seen as an endpoint, whereas from a technical standpoint it is only the beginning. “The EIA is like day zero—it says a lot and at the same time says very little,” Demonte notes, emphasizing that this administrative approval initiates a relationship that may extend for 30, 40, or even 50 years. From that point forward, the real variables come into play—factors that rarely occupy the center of public discussion: detailed engineering, construction, commissioning, operations, continuous monitoring, and closure.
Reducing mining to a public hearing or a legislative vote, he warns, reflects a misunderstanding of how the industry actually operates. Sustainability is not defined in a regulatory file; it is “validated every day” through real-world operations—through the stability of infrastructure, water and waste management practices, and the ability to anticipate and mitigate risks before they escalate into conflicts.
In this context, Mendoza faces an additional challenge: twenty years without mining also meant twenty years without continuous technical learning. Demonte recalls that the province was once a central player in Argentina’s mining exploration landscape, a role that gradually faded. “At some point, we forgot that Mendoza was the center of mining exploration in the country, and that was lost,” he states. The absence of large-scale projects not only halted investment, but also disrupted professional training, team development, and the accumulation of applied technical experience.
Today, rebuilding that technical capital is a prerequisite for any meaningful progress. Modern mining requires high standards in geotechnics, hydrology, tailings management, dam stability, and closure planning. Without trained teams and companies capable of applying these standards on the ground, any project remains incomplete—even where political will or a clear regulatory framework exists.
Against this backdrop, Demonte highlights the importance of companies that chose to maintain a presence in Mendoza during the years of stagnation. “There are companies that stayed when there was no development, and today they can contribute that accumulated experience to ensure processes are carried out in the best possible way,” he notes, underscoring the value of local capabilities aligned with international standards. This technical continuity, he explains, helps prevent improvisation and improves project quality from the design stage onward.
The same logic applies to the issue of social license, another sensitive dimension of the debate in Mendoza. From his perspective, social license is neither a preliminary requirement nor a final outcome. “Social license is not a snapshot; it is a process,” he says. It depends on transparency, the quality of information, and how projects are designed and operated over time. In that sense, Demonte stresses that today’s global mining industry has the technical tools to address any concern objectively: “Any question or concern can be raised and resolved through technical analysis, if there is the will to do so.”
This approach also shapes the discussion around suppliers and local development. For Demonte, closing the system from the outset is not a viable solution. “Prohibiting for the sake of prohibiting doesn’t work; at the beginning, a mix of more experienced companies and local firms is needed, because that is where knowledge transfer takes place,” he explains. The goal, he clarifies, is not assistance, but rather “to leave real tools so people can gain skills, work, and grow.”
The conversation leads to a clear conclusion: mining is not defined by a single political moment or an isolated administrative act. It is defined by the quality of engineering, the continuity of oversight, and the ability to sustain processes over decades. For Mendoza, the fundamental challenge is not merely to debate projects, but to relearn how to manage long-term mining development. Without this technical rebuilding, any progress will be fragile. With it, the province can move beyond a stalled debate and approach mining for what it truly is: a complex, demanding, and deeply technical industry—one that proves itself over time, not through rhetoric.
