Executive Summary

  • Aldebaran Resources reports assay results from the remaining 17 infill drill holes of its 2024/2025 field season at the Altar project, completing reporting for the entire program.
  • Several long intervals returned robust CuEq grades (e.g., 816 m @ 0.53% CuEq, 736 m @ 0.35% CuEq), supporting continued resource upgrade potential from Inferred to Measured & Indicated categories.
  • Management highlights upcoming milestones: PEA in Q3‑2025, mineral resource update Q4‑2025/Q1‑2026, and a PFS in Q4‑2026.

Key Details

  • Hole ALD-25-057EXT: 816.15 m @ 0.53% CuEq from 184 m depth; includes 410.00 m @ 0.68% CuEq from 530 m depth.
  • Hole ALD-25-081DEXT: 491.10 m @ 0.51% CuEq from 411 m depth; includes 137.00 m @ 0.61% CuEq from 622 m depth (bypass of lost extension hole).
  • Hole ALD-25-132EXT: 721.15 m @ 0.41% CuEq from 144 m depth; includes 112.15 m @ 0.66% CuEq from 753 m depth.
  • Hole ALD-25-183EXT: 736.00 m @ 0.35% CuEq from 240 m depth; includes 138.00 m @ 0.61% CuEq from 838 m depth.
  • Hole ALD-25-251B: 836.60 m @ 0.44% CuEq from 247 m depth.
  • Hole ALD-25-252: 561.50 m @ 0.42% CuEq from 438.5 m depth.
  • Hole ALD-25-255: 685.80 m @ 0.41% CuEq from 299.7 m depth; includes 371.50 m @ 0.57% CuEq (614 m) and 214.00 m @ 0.71% CuEq (688 m).
  • Additional holes (ALD-25‑030BEXT, ‑171EXT, ‑180EXT, ‑200EXT, ‑250, ‑253‑258) reported with intervals ranging from ~84 m to 836 m and CuEq values between 0.13%–0.71%.
  • Assay methodology: CuEq calculated using Cu, Au (US$1,400/oz, 50% recovery), Ag (US$18/oz, 51% recovery) and Mo (US$10/lb, 70% recovery). Formula: Cu % + (Au g/t × 0.34025) + (Ag g/t × 0.00446) + (Mo ppm × 0.00023).
  • Qualified Person: Dr. Kevin B. Heather, Chief Geological Officer and Director, reviewed and approved technical data under NI 43‑101.

Notable Quotes

“With all holes from the 2024/2025 field program now reported, the next major milestones for the Altar project are the PEA in Q3‑2025, the mineral resource update in Q4‑2025/Q1‑2026, and the PFS in Q4‑2026.” – John Black, CEO

“The results reported today… demonstrate the continuity and grade consistency of the Altar mineralization, which will increase the confidence level of the next mineral resource as we move the project to the PFS stage.” – Kevin B. Heather, Chief Geological Officer
