Aldebaran Resources Posts Drill Results for Altar Project, Argentina

Why It Matters

The strong, continuous grades de‑risk the Altar deposit and move Aldebaran closer to a bankable study, positioning it to capture rising copper demand and attract financing.

Key Takeaways

• Seven infill holes returned >800 m of ≥0.45% CuEq
• Hole ALD‑26‑173EXT delivered 1,339 m averaging 0.45% CuEq
• Results support upgrading inferred resources to measured & indicated
• Updated resource estimate slated for Q3 2025 after 40,000 m drilling
• Pre‑feasibility study targeted for completion Q2/Q3 2027

Pulse Analysis

The Altar Project sits within Argentina’s prolific San Juan porphyry belt, a region that hosts world‑class assets such as Los Pelambres and Los Azules. Aldebaran controls an 80% stake and has been systematically expanding the known orebody through a multi‑year drilling campaign. By focusing on infill drilling, the company aims to tighten the geological model, confirm continuity, and provide the data needed to re‑classify large swaths of inferred mineralization into higher‑confidence categories, a critical step for any future financing.

The latest seven holes underscore the deposit’s scale. Intercepts exceeding 1 km at grades above 0.45% copper‑equivalent, and a standout 500‑metre segment at 0.71% CuEq, illustrate a robust, vertically extensive system. Such results not only validate the earlier resource model but also supply fresh inputs for metallurgical testing and pit design. The inclusion of extensions to previously drilled holes further refines the three‑dimensional understanding of the orebody, enabling more accurate predictions of recoverable metal and informing decisions on open‑pit versus underground extraction.

Looking ahead, Aldebaran’s roadmap includes a Q3 2025 resource update that will incorporate over 40,000 m of new drilling, followed by a pre‑feasibility study slated for completion in the second half of 2027. These milestones are timed to coincide with a tightening global copper market, where demand from renewable‑energy and electric‑vehicle supply chains is outpacing supply. A higher‑confidence resource and a clear path to production could position Aldebaran as an attractive partner for strategic investors seeking exposure to copper‑gold projects in South America.
