Aldebaran Reports High-Grade Copper-Gold Intercepts at Altar Project — Aldebaran Resources Inc.

Event summary

Aldebaran reported high-grade copper-gold intercepts at its Altar project in Argentina, including 513 meters of 1.06% CuEq.
The results are from six holes in the 2025-2026 infill and geotechnical drilling program aimed at upgrading resource categories.
The updated mineral resource estimate is now expected in October 2026, delayed from September due to assay lab turnaround times.
The pre-feasibility study for the Altar project is still on track for Q2/Q3 2027.
The Altar project is part of a cluster of world-class porphyry copper deposits in San Juan Province.

The big picture

Aldebaran's latest drill results at the Altar project highlight the potential scale and grade of the deposit, which is situated among other world-class porphyry copper projects in Argentina. The strategic significance lies in the project's ability to attract investment and development capital in a region known for large-scale copper-gold mining operations. The upcoming mineral resource estimate and pre-feasibility study will be critical in determining the project's economic viability and its position within the global copper market.

What we're watching

Resource Upgrade Impact: How the conversion of Inferred resources to Measured & Indicated categories will affect the project's feasibility and valuation.
Geotechnical Data: Whether the oriented drill holes will provide sufficient data for both open pit and potential underground mine designs in the pre-feasibility study.
Market Timing: The pace at which Aldebaran can advance the Altar project to production, given the competitive landscape of porphyry copper deposits in the region.
