Drilling Results

Aldebaran Resources Inc. reports 1,728.9 meters of 0.45% copper equivalent from 2025-2026 drilling at Altar project in San Juan, Argentina.

Key Mineral Grades

The results include 756 meters of 0.68% copper equivalent with 0.61% copper, 0.03 g/t gold, and 2.12 g/t silver at 965 meters depth.

Additional Drill Holes

918.8 meters of 0.62% copper equivalent with 0.58% copper, 0.09 g/t gold, and 1.58 g/t silver reported from 59 meters depth.

Geotechnical Focus

Several drill holes were designed exclusively for geotechnical studies in pit wall areas where mineralization was not expected.

CEO Statement

John Black, CEO, stated that a mineralized interval exceeding 1.7 kilometers underscores the scale of the Altar system and supports updated resource estimates.

“A mineralized interval exceeding 1.7 kilometres in a single drill hole underscores the immense scale of the Altar system.”

Geological Officer Statement

Kevin B. Heather, Chief Geological Officer, noted the project's long continuous intervals of copper mineralization and exceeded expectations.

“The Altar project continues to amaze us with long continuous intervals of copper mineralization.”

Resource Update

The 2026 resource update will incorporate over 40,000 meters of drilling since late 2024 and 30,000 meters at Radio Porphyry target.

Radio Porphyry Target

Radio Porphyry has never been included in a mineral resource estimate, making this an important milestone for the project.

Pre-Feasibility Study

The Pre-Feasibility Study is scheduled for completion in 2027, positioning Aldebaran for future projects.

Drilling Campaign

The 2025-2026 drilling campaign results have exceeded expectations and improved geological and geotechnical models.
