Kobrea Exploration Corp. (CSE: KBX) has released an update on its ongoing diamond drilling program at the El Perdido porphyry copper-gold-molybdenum system in Mendoza Province, Argentina. The announcement, dated 9 Apr 2026, confirms that a chalcocite enrichment zone has been identified and that drilling is actively continuing ahead of the winter season.
The El Perdido drill results to date have confirmed the presence of a copper-bearing porphyry system at the first regional target tested. Kobrea Exploration stock forecast interest is expected to grow as the Company advances its Argentina copper porphyry projects with a fifth drill hole now underway.
Four Holes Completed and Core Samples Awaiting Laboratory Results
Kobrea Exploration Corp. drilled the initial three diamond drill holes at the El Perdido porphyry copper-gold-molybdenum prospect to target depths of 500 metres each. Drill holes DD26ELP001, DD26ELP002, and DD26ELP003 were completed to depths of 603 metres, 474 metres, and 662 metres, respectively.

All core samples from the first four drill holes have been sent to Alex Stewart International’s laboratory in Mendoza, with assay results currently pending.
Fourth Hole Abandoned Due to Fault Zone but Delivers a Key Finding
Drill hole DD26ELP004 had a target depth of 600 metres but was abandoned at 200 metres. The abandonment was due to technical complications related to unstable rock conditions associated with a significant fault zone.
Despite this, the hole drilled through 128 metres of leached intrusive rock before intersecting intermittent chalcocite enrichment coating and, in cases, replacing primary sulphides comprised dominantly of pyrite with lesser chalcopyrite. Chalcocite enrichment was observed to 168 metres before the fault zone made further progress impossible.
Chalcocite Confirmation Validates the El Perdido Target Model
Vice President of Exploration Rory Ritchie commented directly on what the fourth hole means for the broader El Perdido drill results:
“The presence of chalcocite as observed in drill hole DD26ELP004 confirms the presence of a chalcocite enrichment zone preserved at El Perdido. Given the degree of leaching in the upper portions of the system, that was originally hypothesised but not certain. Drill hole DD26ELP004 has confirmed our target model. As we continue in the early phases of a diamond drilling program, with the goal of qualifying the porphyry system at El Perdido, we are confident we will observe chalcocite in other areas, beneath the leached capping, enriching hypogene sulphide mineralisation beneath.”
Fifth Drill Hole Commenced and Third Drill Pad Now Under Construction
Kobrea Exploration Corp. has engaged Major Drilling Argentina to complete the 2026 drilling program. Major Drilling commenced drill hole DD26ELP005 on 1 Apr 2026 at drill pad number two.

The fifth hole is designed to complete the original objective of drill hole DD26ELP004, which was to extend a mineralised zone encountered in DD26ELP001 to depth. That zone comprised strong pyrite-chalcopyrite-molybdenite stockwork veining within potassically altered early mineral quartz diorite porphyry.
Third Drill Pad Opens Up the Southwestern Portion of the System
Construction of a third drill pad has commenced at the El Perdido porphyry system. The new pad will allow additional drilling to test the southwestern portion of the El Perdido Project, expanding the spatial coverage of the Argentina copper porphyry projects program.

Chief Executive Officer James Hedalen confirmed the drilling ambition for the season:
“Despite complications associated with the drilling of hole DD26ELP004, drilling continues at the El Perdido porphyry system. We have intersected a copper bearing porphyry system in the first regional target tested. We intend to drill as much as we can before the winter season sets in.”
About El Perdido and Kobrea’s Argentina Portfolio
The El Perdido Project sits within the Western Malargue Copper Project, which covers 73,334 hectares. The project is located within the Neogene Porphyry Belt, a well-known mineralised corridor extending across central Chile and into Argentina.
Kobrea Exploration Corp. holds the right to earn a 100% interest in seven projects totalling over 733 km2 in southwestern Mendoza Province, Argentina. These assets are regarded as highly prospective for large-scale porphyry copper and copper-gold mineralisation. Kobrea also holds a 100% interest in the Upland Copper Project in British Columbia, Canada.
KBX CSE Share Price

Industry Outlook
Global demand for copper continues to rise, driven by the accelerating buildout of energy transition infrastructure, including electric vehicles, renewable energy systems, and grid modernisation. Porphyry copper-gold systems remain among the most sought-after deposit types globally, given their large scale and multi-metal potential.
Argentina’s Mendoza Province sits within one of South America’s most prospective porphyry belts. Growing investor focus on Argentina copper porphyry projects reflects the region’s geological credentials and the increasing importance of securing new copper supply pipelines.
Future Direction and Impact on Kobrea Exploration Stock Forecast
For investors tracking the Kobrea Exploration stock forecast, the near-term catalyst is the receipt of analytical results from Alex Stewart International’s laboratory for all four completed drill holes. A positive assay outcome would materially advance the Company’s understanding of grade and continuity at El Perdido.
The fifth drill hole is now active, and construction of a third drill pad has expanded the footprint of the drill program. The Company’s stated intention is to drill as much as possible before the Argentine winter season restricts access to the site.
The El Perdido drill results so far have confirmed a copper-bearing porphyry system and a chalcocite enrichment zone. These are meaningful technical milestones for an early-stage Argentina copper porphyry project explorer operating at the first regional target it has tested.
Frequently Asked Questions
Q1. What are the latest El Perdido drill results from Kobrea Exploration?
Ans. Four drill holes have been completed. DD26ELP004 confirmed a chalcocite enrichment zone. All core samples are at the lab and results are pending.
Q2. Why was drill hole DD26ELP004 abandoned?
Ans. The hole was stopped at 200 metres due to unstable rock conditions linked to a significant fault zone, short of its 600 metre target depth.
Q3. What is drill hole DD26ELP005 targeting?
Ans. It is designed to extend the mineralised zone found in DD26ELP001, which showed strong pyrite-chalcopyrite-molybdenite stockwork veining in potassically altered porphyry.
Q4. Where is the El Perdido Project located?
Ans. It is located in Mendoza Province, Argentina, within the Neogene Porphyry Belt along the Chile-Argentina border.
Q5. What does the chalcocite find mean for the Kobrea Exploration stock forecast?
Ans. It validates the target model at El Perdido. The Company expects to find chalcocite in additional areas beneath the leached capping, which would support further resource definition drilling.
