Aldebaran Resources Inc. and Centauri Minerals Inc. Announce Significant Increase in Mineral Resources for the Rio Grande Gold-Copper Project in Salta, Argentina
Aldebaran Resources Inc. and Centauri Minerals Inc. announced the results of an updated mineral resource estimate for the Rio Grande gold-copper project in Salta, Argentina (the "MRE"). Indicated Resources containing 1.45 million ounces of gold, 384,000 tonnes of copper and 12.7 million ounces of silver; 153.7 million tonnes grading 0.29 g/t gold, 0.25% copper and 2.6 g/t silver; Inferred Resources containing 1.55 million ounces of gold, 420,000 tonnes of copper and 17.8 million ounces of silver; 220.8 million tonnes grading 0.22 g/t gold,0.19% copper and 2.5 g/t silver; Mineralization is still open in several directions, with significant porphyry potential beneath the current resource, with historical drilling hitting 257.2 m of 1.20 g/t gold, and 0.53% copper in porphyry dykes. SLR Consulting (Canada) Ltd. ("SLR") was retained by Centauri to complete a National Instrument ("NI") 43-101 Technical Report and Mineral Resource Estimate update for the Rio Grande gold-Copper project, located in Salta Province, Argentina. To generate a new resource pit shell, SLR applied new Whittle input parameters to the 2018 resource block model from the NI 43-101 Technical Report and MRE completed by Roscoe Postle Associates Inc. ("RPA" - since acquired by SLR in 2019) and dated August 17, 2018. There has been no new drilling or trenching work carried out at Rio Grande since 2013. Wireframes for geology and mineralization were constructed in Leapfrog Geo based on geology sections, assay results, and lithological information. Blocks were classified as Indicated and Inferred based on the following criteria: Indicated Mineral Resources: Blocks located within areas drilled at 100 m spacing and demonstrating reasonable continuity above the cut-off grade; and Inferred Mineral Resources: Blocks located within 200 m of the nearest drill hole. The Rio Grande project is situated next to the operating Lindero Au-Cu mine and it includes five Mineral Resource areas, ranked by relative contribution: Discovery-Sofia, Central (West and East), North, Southwest, and Seven. Drilling completed to date has primarily tested the upper portions of the mineralized system, however many of the existing drill holes terminated in sulphide mineralization. This potential is conceptual in nature, and insufficient drilling has been completed to define additional Mineral Resources; however, the observed continuity of alteration and structural controls supports continued exploration. In addition, Centauri is building out a management and exploration team to advance the exploration portfolio, including developing new drill targets for the Rio Grande project with the intention to commence a drill program on the project in 2026. In November 2024, the Company announced an updated mineral resource estimate for Altar, prepared by Independent Mining Consultants Inc. ("IMC") and based on the drilling completed up to and including the 2023-24 field season (independent technical report prepared by IMC, Tucson, Arizona, titled "Technical Report, Estimated Mineral Resources, Altar Project, San Juan Province, Argentina", dated December 31, 2024). In October 25, 2024, the Company announced a Preliminary Economic Assessment for Altar, prepared by SRK Consulting Inc. ("SRK") (independent technical report prepared by SRK, titled "SRK") (independent technical report prepared by SRK Consulting Inc., titled "SRK, titled "SRK"), titled "SRK") ("SRK") (independent technical Report, titled "Technical Report, estimated Mineral Resources, Altar Project.
