Rhea-AI Summary

Kobrea Exploration Corp (OTCQB: KBXFF) reports Phase 1 drilling at the El Perdido porphyry system in Mendoza Province has reached 1,739 metres across three holes, and a fourth diamond drill hole has commenced ~220 metres east of the initial pad with a 600 metre target depth.

The program tests a pyrite-chalcopyrite-molybdenum stockwork in potassically altered quartz diorite; Kobrea holds rights to earn 100% interest in seven projects totaling 733 km2.

Positive

• 1,739 metres drilled to date in Phase 1
• Program expanded to a fourth drill hole to follow up geological observations
• Kobrea can earn 100% interest in seven projects totaling 733 km2

Negative

• No assay results reported yet from Phase 1 drilling, leaving mineral grades unconfirmed

Vancouver, British Columbia--(Newsfile Corp. - March 4, 2026) - Kobrea Exploration Corp. (CSE: KBX) (FSE: F3I) (OTCQB: KBXFF) ("Kobrea" or the "Company") is pleased to announce that the Phase 1 diamond drill program at the El Perdido porphyry system is progressing as planned, with a total meterage of 1,739 metres drilled to date in three diamond drill holes. Based on geological observations of drill core, the Company has expanded upon the originally planned three drill hole program and has commenced a fourth hole approximately 220 metres east of the initial drill pad. Kobrea holds the right to earn a 100% interest in 7 projects totaling 733 km² in southwestern Mendoza Province, Argentina (see the Company's August 19, 2024 news release for details).

"The drill program at El Perdido continues to advance efficiently, supported by the efforts of our contractors and employees on site," stated James Hedalen, CEO. "Geological observations from the first three holes provided valuable geological information that supports expanding the program with a fourth hole to further test and refine our understanding of the system."

El Perdido Phase 1 Drilling

The initial three diamond drill holes at the El Perdido porphyry copper-gold-molybdenum prospect had target depths of 500 metres each. Drill holes DD26ELP001, DD26ELP002 and DD26ELP003 were drilled to depths of 603 metres, 474 metres and 662 metres, respectively.

Drill hole DD26ELP004 has a target depth of 600 metres. This drill hole is targeting a zone of strong pyrite-chalcopyrite-molybdenum stockwork veining within potassically altered early mineral quartz diorite porphyry encountered in drill hole DD26ELP001, with the intent of extending the mineralized zone to depth (Figure 1,2).
