Argentina Metals consolidated in just a few months one of the largest exploration portfolios currently held by private companies in Mendoza. The Canadian company’s expansion began in November 2025 and, by April 2026, had allowed it to assemble around twenty mining properties mainly distributed across Malargüe, many of them linked to the province’s western copper corridor and areas included within the Malargüe Western Mining District (MDMO).

The company’s first public transaction took place in November 2025, when Argentina Metals announced the acquisition of Las Estrellas, Zascar, Vecindario, and La Herradura—four properties in Mendoza negotiated with Apeleg, the private group holding the largest number of projects within the first batch of the southern Mendoza mining district. That package marked both the formal arrival of the company in the province and the beginning of its territorial consolidation strategy.
The Acquisition of the Mirasol Portfolio and Territorial Expansion
The company’s most significant move came in January 2026, when Argentina Metals acquired the so-called “Mendoza Portfolio” from Mirasol Resources through Nueva Gran Victoria S.A. The operation incorporated 14 properties: Riesling, Malbec, Merlot, Sirah, and the Pinot I through Pinot X projects, covering an area close to 89,070 hectares.
Part of these assets already had approved exploration Environmental Impact Declarations (DIA) within MDMO I, particularly Malbec, Merlot-Sirah, and Riesling, quickly transforming the company into one of the main holders of exploration properties within the district.
In February 2026, the company continued expanding its portfolio through the acquisition of El Salado and La Quimera, adding approximately 9,980 additional hectares.
The expansion continued in April 2026 with the incorporation of Angellica, Roma, Veneto, and Belluno, properties acquired from Andean Exploration S.A., a company belonging to the Maref Group portfolio.
That package added another 19,151 hectares to Argentina Metals’ inventory and completed the 24 acquired properties currently shown in the company’s corporate presentation.
Identified Properties and Technical Focus on Las Estrellas
By compiling all press releases and public documentation, Argentina Metals’ identified portfolio in Mendoza now consists of: Las Estrellas, Zascar, Vecindario, La Herradura, Riesling, Malbec, Merlot, Sirah, Pinot I, Pinot II, Pinot III, Pinot IV, Pinot V, Pinot VI, Pinot VII, Pinot VIII, Pinot IX, Pinot X, El Salado, La Quimera, Angellica, Roma, Veneto, and Belluno.
The company also states that it owns two additional “staked” projects totaling another 14,573 hectares, although those assets have not yet been publicly identified in the reviewed documents.
Among the entire portfolio, Las Estrellas currently appears as the company’s most advanced project in terms of technical exposure.
There, the company has already reported geochemical work, surface sampling, ground magnetometry, and the generation of structural targets, while also highlighting the project’s immediate proximity to El Perdido, Kobrea Exploration’s project that currently concentrates a significant portion of deep exploration activity within MDMO I.
