Aldebaran Resources Inc. reported results for holes ALD-23-227 and ALD-23-228 from its ongoing drilling campaign at the Altar copper-gold project in San Juan Province, Argentina. Hole ALD-23-227 was a 200 m step out hole to the north from previously released ALD-22-223 (1,167.50 m of 0.48% CuEq – see March 1, 2023 press release). ALD-23-228 was a 200 m step out to the north from previously released ALD-23-225B (951.20 m of 0.60% CuEq – see May 31, 2023 press release).

Both holes have provided valuable additional pierce points into the promising geophysical anomaly beneath and lateral to current resources at the Altar project. In addition, both ALD-23-227 and ALD-23-228 tested the northern extension of the newly identified Altar United trend. ALD-23-227 entered favourable host rocks at approximately 1,000 m depth, and then returned attractive grade mineralization until the end of the hole.

ALD-23-228 hit the favourable host rock formation at approximately 750 m depth and thereafter returned some of the highest-grade copper mineralization encountered on the project to date, demonstrating that the high-grade mineralization found previously in hole ALD-23-225B has continuity. Highlights ALD-23-228 565.60 m of 0.60% CuEq from 676.00 m depth Including 474.60 m of 0.69% CuEq from 767.00 m depth Including 329.60 of 0.80% CuEq from 912.00 m depth Including 58.00 m of 1.02% CuEq from 1,011.00 m depth Hole ended in 74.60 m of 0.80% CuEq with the last sample running 0.96% CuEq The Company is actively drilling with four rigs. Holes ALD-23-229, ALD-23-230, ALD-23-231 and ALD-23-189EXT are completed and were terminated at 1,413.60 m, 611.40 m, 1,211.80 m, and 1,246.00 m respectively: all pending final assays.

Hole ALD-23-189EXT, is an extension of a historically drilled hole ALD-12-189, which was originally terminated at 592 m depth. At the date of this release, holes ALD-23-232, ALD-23-124EXT and ALD-23-228EXT were active and at approximately 1064.70 m, 751.00 m and 1,358.70 m depths, respectively. Hole ALD-23-124EXT is an extension of a historically drilled hole ALD-12-124, which was originally terminated at 226.50 m depth.

A fourth rig just commenced drilling on hole ALD-23-233 and will not reach its planned target depth during the current campaign but will be left in good standing in order to re-enter and continue the hole at the start of the next field campaign. The Company plans to begin demobilizing the drill rigs and then shut down the camp to close out the 2022/2023 drill campaign in the coming week. The Company has re-entered hole ALD-23-228 and is actively drilling to test for the deeper extension of this higher-grade mineralization ALD-23-227 198.50 m of 0.50% CuEq from 1,040.00 m depth Including 60.50 m of 0.63% CuEq from 1,178.0 m depth Hole ended in 31.50 m of 0.69% CuEq .
