Aldebaran Resources posts drill results for Altar Project, Argentina
Aldebaran Resources Inc. [TSXV: ALDE; OTCQX: ADBRF] provided results of seven holes from the infill drilling program at the Altar Project in San Juan, Argentina. The goal of these holes was to upgrade resource blocks classified as Inferred to the Measured & Indicated categories.

ALD-26-036EXT: 826.10 metres of 0.54% CuEq1 from 124 metres depth, including 98 metres of 1.07% CuEq from 140 metres depth, including 78 metres of 0.68% CuEq from 280 metres depth.
ALD-26-187DEXT: 934.00 metres of 0.37% CuEq from 324 metres depth.
ALD-26-180EXT: 895 metres of 0.28% CuEq from 496 metres depth.
ALD-26-259: 513 metres of 0.47% CuEq from 924 metres depth, including 59 metres of 0.62% CuEq from 1,378 metres depth.
John Black, CEO of Aldebaran, commented: “The holes reported today continue to demonstrate the size and quality of the Altar deposit. Several of the holes ended in attractive grade mineralization, which speaks to the scale of the mineralized system at Altar. As we look forward, the near-term catalysts for Aldebaran are the release of additional drill results from the project and an updated mineral resource estimate in Q3 of this year, which will incorporate more than 40,000 m of drilling since our last resource estimate in 2024. This resource will set the table for the Pre-Feasibility Study, which will completed in Q2/Q3 2027.”
Kevin B. Heather, Chief Geological Officer of Aldebaran, commented: “An important aspect of any resource infill drill program is to demonstrate continuity of mineralization and grade; both of which the current program continues to successfully deliver. In addition, the infill drill holes provide critical new technical information that will refine our geological models and add to our orebody knowledge, both of which will facilitate more informed decisions on processing methodologies, as well as open pit and underground infrastructure design in the upcoming Pre-Feasibility Study.”
Table 1 below shows detailed assays for all seven holes. Figure 1 displays a plan map of the completed drill hole locations, while figures 2 to 7 display cross sections of the holes reported herein. Holes with the suffix EXT are extensions of previously drilled holes.
Aldebaran is a mineral exploration company that was spun out of Regulus Resources Inc. in 2018 and has the same core management team. Aldebaran holds an 80% interest in the Altar copper-gold project in San Juan Province, Argentina.
The Altar project hosts multiple porphyry copper-gold deposits with potential for additional discoveries. Altar forms part of a cluster of world-class porphyry copper deposits which includes Los Pelambres (Antofagasta Minerals), El Pachón (Glencore), and Los Azules (McEwen Copper).
In November 2024 the company announced an updated mineral resource estimate for Altar, prepared by Independent Mining Consultants Inc. and based on the drilling completed up to and including the 2023-24 field season. In October 2025 the company announced a Preliminary Economic Assessment (PEA) for the Altar Project.
