Kobrea Commences Exploration at Western Malargüe Copper Projects

Kobrea holds the right to earn a 100% interest in the 7 projects comprising the Western Malargüe Copper Projects, totaling over 733 km2 in southwestern Mendoza Province, Argentina

Kobrea Exploration Corp. has announced that field crews have been mobilized to begin the Company’s 2025 exploration program across multiple porphyry prospects within its Western Malargüe Copper Projects in southwestern Mendoza Province, Argentina. Kobrea holds the right to earn a 100% interest in seven projects spanning over 733 km² in the region.

“We are first movers into the newly established Western Malargüe Mining District in Mendoza Province, Argentina, and have an opportunity to make discoveries by drilling for the first time in this part of a world-class porphyry copper belt. Host to numerous Tier 1 porphyry copper deposits, the Neogene Porphyry Belt includes Los Bronces/Rio Blanco and El Teniente,” commented James Hedalen, CEO of Kobrea. “Our inaugural program will include geological mapping and geochemical sampling of multiple porphyry copper systems along with geophysical surveys, culminating in the very first drill program ever conducted on these projects.”

Initial Exploration Activities

The exploration campaign will begin with geological mapping, rock chip sampling, and talus sampling, followed by targeted geophysical surveys. Following these initial steps, the Company intends to conduct a diamond drilling program at select prospects, including the El Perdido target, where historical exploration data from previous operators suggest a large-scale porphyry copper-gold-molybdenum system.

El Perdido Prospect

• Size & Location: Encompassing 6,878 hectares, El Perdido is host to a porphyry Cu-Au-Mo system defined at surface but still untested by drilling.
• Porphyry Characteristics: A 2 x 3-kilometre hydrothermal alteration footprint exhibits classic porphyry alteration assemblages with localized potassic alteration at surface.
• Surface Expressions: Within a 900 x 500-metre zone, quartz stockwork veining coincides with anomalous copper-gold-molybdenum rock geochemistry. The presence of quartz diorite porphyritic intrusions, localized biotite breccias, and potassic alteration in an area otherwise dominated by phyllic alteration further confirms the porphyry potential.
• Geophysics: Historical ground magnetometer data from 2013 delineates a subsurface magnetic anomaly measuring roughly 1,000 metres across and extending 1,000 metres deep, surrounded by areas of lower magnetism—an attractive geophysical target for a porphyry Cu-Au-Mo system.

Western Malargüe Mining District

The Western Malargüe Mining District (“WMMD”) was created by the government of Mendoza through Impulsa Mendoza SA to address the world’s growing demand for critical metals essential to the energy transition. As part of this initiative, detailed environmental impact and geological studies have been completed to streamline the permitting process for exploration and development activities.

On November 12, 2024, the provincial legislature ratified environmental impact statements for 34 projects, including two of Kobrea’s projects, El Perdido and Elena. These approvals allow for mineral exploration activities—including drilling—to proceed. This milestone follows a thorough process of public hearings, citizen participation, and technical analysis. Additional Kobrea projects within the WMMD are expected to undergo the same approval process in the coming months.
