Aldebaran Continues To Expand Mineralization at Altar Copper-Gold Project

The Altar project hosts multiple porphyry copper-gold deposits with potential for additional discoveries. Altar forms part of a cluster of world-class porphyry copper deposits which includes Los Pelambres, El Pachón and Los Azules.

Aldebaran Resources Inc. has reported results from the first four drill holes of the 2023/2024 field campaign at the Altar copper-gold project in San Juan, Argentina. Due to snow constraints at the time of commencing the current field season, three of the holes (ALD-23-162EXT, ALD-23-166EXT, and ALD-23-194EXT) were significant step-outs to test for the southern extension of mineralization within the large, conductive geophysical anomaly at Altar. As expected, those three holes did not intersect the porphyry intrusive rocks typically associated with the higher-grade mineralization at Altar United, however, they did intersect low- to moderate-grade mineralization in wall rocks (andesites and rhyolites) that will add resources to a previously undrilled area. Hole ALD23-234 was designed to test an area in the current resource model that was defined as waste due to lack of drilling. Hole ALD-23-234 successfully hit mineralization and will likely convert waste to resources in the upcoming mineral resource update for the project.

John Black, Chief Executive Officer of Aldebaran, commented as follows: “These first four holes add valuable information to our geological understanding of the Altar project. Holes ALD-23-162EXT, ALD-23-166EXT and ALD23-194EXT have helped define the southern extents of the Altar United trend, while still adding substantial mineralization to Altar. Hole ALD-23-234 intersected a long run of mineralization in an area previously thought to be waste. This should add substantial value when we transition to a resource update later this year. When we commenced the field campaign in late 2023, our options for drill pad locations were restricted by several areas of the project still having substantial snowfall. We now have access to the entire project and we are currently drilling from more opportune locations to test the extent of the higher-grade mineralization previously encountered in the Altar United Trend and to continue growing the overall mineralized footprint of the Altar project.”

Dr. Kevin B. Heather, Chief Geological Officer of Aldebaran, commented as follows: “The results reported here are important as they show that the Altar mineralized footprint is much larger and extends mineralization into areas previously not drilled. These drill holes will contribute valuable supporting mineralized blocks to help capture better mineralized drill holes, drilled last year, in the upcoming mineral resource update slated for H2 2024.
