Recent Company History

This announcement continues a sequence of de-risking steps in Kobrea’s Western Malargüe portfolio. On Jul 29, 2025, the company secured environmental approvals for road construction and drilling at El Perdido, with a strong positive price reaction. Subsequent news on Aug 6 expanded the porphyry target footprint, and on Aug 13 Kobrea advanced its option payments on seven projects. On Nov 4, it began constructing the drill access road. Today’s broad exploration approvals across El Destino, Sofi, Cuprum and others build on that permitting and development trajectory.

Market Pulse Summary

This announcement confirms that Kobrea’s projects at El Destino, Sofi, Cuprum and El Perdido are fully approved for mineral exploration, including drilling, following the ratification of Environmental Impact Statements for 27 exploration projects. It reinforces a pattern of permitting progress in Mendoza and supports the company’s planned maiden diamond drilling at El Perdido. Investors may watch for drill results, further regulatory steps, and updates on broader development approvals like the San Jorge porphyry copper project.

Key Terms

environmental impact statements regulatory

"have ratified by law, Environmental Impact Statements for an additional 27 exploration projects"

Environmental impact statements are formal reports that describe how a proposed project or activity is likely to affect air, water, land, wildlife and communities, and outline steps to avoid or reduce harm. For investors they matter because these reports can determine whether a project gets permits, faces delays, extra costs or legal challenges—think of it as a detailed home inspection that can reveal hidden repairs and timelines before you buy.

porphyry copper technical

"The San Jorge porphyry copper project is located in Uspallata"

A porphyry copper deposit is a large, low-to-medium grade body of rock in which copper and often other metals are spread throughout like specks in a loaf, formed by mineral-rich fluids from igneous intrusions. These deposits matter to investors because they are the world’s dominant source of mined copper, offering long-lived mines and predictable production profiles, but they also require large upfront capital and multi-year development.

diamond drilling technical

"maiden diamond drilling program set to commence in the coming weeks"

Diamond drilling is a method that uses a rotating drill with industrial diamonds on the bit to cut and retrieve cylindrical rock samples (cores) that preserve the sequence of underground layers. For investors, these cores act like a geological “biopsy,” providing direct, verifiable information about mineral presence, grade and continuity—data that underpins resource estimates, project valuation, drilling risk and financing decisions.

Vancouver, British Columbia--(Newsfile Corp. - December 11, 2025) - Kobrea Exploration Corp. (CSE: KBX) (FSE: F3I) (OTCQB: KBXFF) ("Kobrea" or the "Company") is pleased to announce that the Senate and the Chamber of Deputies of the Province of Mendoza, Argentina, have ratified by law, Environmental Impact Statements for an additional 27 exploration projects in the Western Malargüe Mining District (the "WMMD"). As a result of the approvals, all of Kobrea's projects are now approved for mineral exploration activities, including drilling. At the Company's El Perdido Project, construction of an access road to the drill site is ongoing and construction of an exploration camp is underway in anticipation of the maiden diamond drilling program set to commence in the coming weeks.

"Exploration projects within the Western Malargüe Mining District continue to be overwhelming approved by the Provincial Legislature of Mendoza Province," commented James Hedalen, CEO. "In the session of the Mendoza Senate held on December 9, 2025, in which the Environmental Impact Statements for the additional 27 exploration projects in the Western Malargüe Mining District of Mendoza, including the Kobrea projects, were approved by law, the Environmental Impact Statement of the San Jorge Project was also discussed and approved by law. The San Jorge porphyry copper project is located in Uspallata in northern Mendoza Province (Las Heras District), outside of the Western Malargüe Mining District, but the approval of mine development and construction of this project is a huge step forward for mineral exploration and development in the province of Mendoza. These approvals clearly demonstrate that the provincial government and the people of Mendoza support mining and believe in the economic opportunities that sustainable exploration and development will bring. I would like to congratulate the government of Mendoza, Impulsa Mendoza, the Chamber of Mining in Mendoza and the project vendors for their many years of hard work to get to this point."
