Kobrea Exploration Corp. (KBX.c KBXFF) Advances Copper-Gold-Molybdenum Drilling at El Perdido, Confirms Chalcocite Enrichment
Posted on behalf of Kobrea Exploration Corp. - Kobrea Exploration Corp. (Ticker: KBX.c or KBXFF for US investors) is progressing exploration across a 733 km² land package in Mendoza Province, Argentina, where it holds seven projects prospective for large-scale porphyry systems.
The company is focused on copper and copper-gold targets characterized by extensive alteration zones, anomalous copper ± gold ± molybdenum geochemistry, and porphyry-style veining and intrusions.
Project Update: El Perdido Porphyry System
Earlier this month, Kobrea provided an update on its ongoing diamond drill program at the El Perdido copper-gold-molybdenum porphyry system. The first regional target tested intersected a copper-bearing porphyry system, representing an initial step in evaluating the broader mineralized footprint.
Key Observations from DD26ELP004
Drill hole DD26ELP004 returned the following geological observations:
- 128m of leached intrusive rock near surface.
- Intervals of chalcocite enrichment beneath the leached zone.
- Secondary copper mineralization observed coating and, in some cases, replacing primary sulphides such as pyrite and chalcopyrite.
- Enrichment extending to approximately 168m depth before encountering a fault zone that led to the hole being abandoned.
The identification of chalcocite confirms the presence of a preserved supergene enrichment zone at El Perdido and supports Kobrea’s geological model. This is particularly relevant given the extensive leaching observed near surface, which had previously introduced uncertainty around enrichment potential.
Ongoing Drilling and Expansion Plans
Drilling remains underway, with the current phase focused on:
- Defining the scale and characteristics of the porphyry system.
- Conducting step-out drilling to assess lateral continuity.
- Testing deeper portions of the system beneath the leached cap.
Construction of a third drill pad is also in progress. This additional infrastructure is designed to allow testing of the southwestern extent of the El Perdido porphyry system while increasing operational flexibility as the program advances toward the winter season.
