Aldebaran Resources Inc. has released assay results from seven infill drill holes at its Altar copper-gold project in San Juan, Argentina. The drilling program aimed to upgrade Inferred resource blocks to Measured and Indicated categories. Notable intercepts include 1,339.30 meters grading 0.45% copper equivalent (CuEq) from a depth of 12 meters, including 500 meters of 0.71% CuEq from 326 meters depth. Another hole returned 1,059.20 meters of 0.51% CuEq from 326 meters, including 249.20 meters of 0.71% CuEq.

Management Commentary
John Black, Chief Executive Officer of Aldebaran, stated: "The holes reported today continue to demonstrate the size and quality of the Altar deposit. Several holes ended in attractive grade mineralization, highlighting the scale of the mineralized system. Near-term catalysts include additional drill results and an updated mineral resource estimate in Q3 2026, incorporating over 40,000 meters of drilling since the 2024 resource estimate. This will set the stage for a Pre-Feasibility Study expected in Q2/Q3 2027."
Kevin B. Heather, Chief Geological Officer, added: "An important aspect of resource infill drilling is demonstrating continuity of mineralization and grade, which this program continues to deliver. The infill holes provide critical technical information to refine geological models and support decisions on processing methods and infrastructure design for the upcoming Pre-Feasibility Study."
Technical Details
Copper equivalent (CuEq) values were calculated using metal prices of US$3.00/lb for copper, US$1,400/oz for gold, US$18/oz for silver, and US$10/lb for molybdenum. Recoveries applied were 50% for gold, 51% for silver (based on historical metallurgical test work), and 70% for molybdenum (benchmarked from similar deposits). The formula used is: CuEq % = Cu % + (Au g/t * 0.34025) + (Ag g/t * 0.00446) + (Mo ppm * 0.00023). All intervals represent true thickness of the deposit.
