Aldebaran Resources Inc. to report additional results from two holes at its ongoing drilling campaign at the Altar copper-gold project in San Juan Province, Argentina. Hole ALD-23-224 was drilled in an area with limited previous drilling and was designed to test a coincident MT and DCIP resistivity geophysical anomaly while at the same time testing a 500 m gap between previously released ALD-22-221 and ALD-22-223. Hole ALD-23-224 was terminated at 1,210.50 m and intercepted long runs of mineralization that extends the mineralized footprint well beyond the 2021 resource estimate model.

Hole ALD-23-226 was drilled at the south-eastern edge of the resistivity anomaly and was designed to test the south-eastern extension of mineralization. The hole was collared approximately 700 m to the south of ALD-22-223 and was topographically quite high up the southern mountainside in relation to hole 223. Hole ALD-23-226 was terminated at 1,146.80 m and intercepted pyritic mineralization throughout the hole but did not return significant assays.

Once the hole entered into more favourable host rocks at 1,076 m depth, mineralization improved, as did the assays indicating proximity to the main mineralized porphyry. Drillhole ALD-23-224 was collared approximately 400 m to the west of hole ALD-22-223 and was drilled at -80 degrees inclination and 180 degrees azimuth to a final depth of 1,210.50 m. Drillhole ALD-23-224 intersected unfavourable porphyritic rhyolite rocks until approximately 501 m, where it transitioned to a well mineralized diorite porphyry intrusion until the bottom of the hole. The top 248 m of the hole are strongly fractured and oxidized (i.e., leached) and from 248 m to 501 m, white sericite-pyrite-tourmaline is the dominant alteration, which is locally overprinted by high sulphidation structures characterized by the presence of quartz-pyrite-enargite-chalcopyrite.

Quartz-pyrite-molybdenite veins occur sporadically in this interval as well. Potassic K-feldspar alteration starts at 437 m and is accompanied by strong quartz-chalcopyrite-pyrite-molybdenite veining. Within the diorite porphyry unit, the potassic alteration is consistently overprinted by halo-style green sericite-chalcopyrite-chalcocite-pyrite-bornite assemblages typically carrying multiple percentage sulphides.

Drillhole ALD-23-226 was collared at the southern edge of the Altar East zone and was drilled at -75 degrees inclination and 000 degrees azimuth to a final depth of 1,146.80 m. Drillhole ALD-22-226 intersected fragmental dacitic tuffs over the first 191 m, transitioning to crystal tuffs until 733 m. At 733 m the hole transitions to quartz-eye bearing rhyolite, which continues until 1,076 m depth when more favourable andesite volcanic wall rocks were encountered. Mineralization and alteration increase within the andesite until the end of the hole. The top 63 m of the hole was well fractured and oxidized.

From approximately 280 m until 1,000 m depth alteration is dominantly sericite-tourmaline and chlorite-anhydrite. Mineralization largely consists of pyrite, which is crosscut locally by quartz-enargite-chalcopyrite veins. Molybdenite is observed with increasing frequency towards the bottom of the hole and at 1,000 m depth strong potassic alteration begins and is overprinted locally by green sericite-quartz-chalcopyrite alteration, which continues until the end of the hole.

The Company is actively drilling with four rigs. Holes ALD-23-225B, ALD-23-227 and ALD-23-228 were recently completed at 1,347.2 m, 1,238.5 m and 1,241.6 m respectively. Hole 23-189EXT, which recently commenced, is an extension of a historically drilled hole ALD-12-189 which was originally terminated at 592 m depth.

At the time of this release, hole 189EXT was at approximately 1,000 m depth and holes ALD-23-229, ALD-23-230 and ALD-23-231 were active and at approximately 950 m, 500 m, and 500 m depths respectively. The Company plans to continue drilling until weather permits, which is currently anticipated to be sometime in June.
