Aldebaran Resources Inc. Provides Results of Seven Holes from Infill Drilling Program at Altar Project in San Juan, Argentina
Aldebaran Resources Inc. provided results of seven holes from the infill drilling program at the Altar project in San Juan, Argentina. The goal of these holes was to upgrade resource blocks classified as Inferred to the Measured & Indicated categories. ALD-26-173EXT: 1,339.30 m of 0.45% CuEq1 from 12 m depth, including 500 m of 0.71% CuEq1 from 326 m depth, including 96 m of 0.94% CuEq1 from 436 m depth, including 60 m of 1.00% CuEq1 from 606 m depth. ALD-26-199EXT: 1,059.20 m of 0.51% CuEq1 from 326 m depth, including 221.50 m of 0.61% CuEq1 from 868.50 m depth, including 249.20 m of 0.71% CuEq1 from 1,136 m depth, including 54 m of 0.92% CuEq1 from 1,270 m depth. ALD-26-174EXT: 1,198.00 m of 0.43% CuEq1 from 92 m depth, including 388 m of 0.63% CuEq1 from 530 m depth. ALD-26-036EXT: 826.10 m of 0.54% CuEq1 from 124 m depth, including 98 m of 1.07% CuEq1 from 140 m depth, including 78 m of 0.68% CuEq1 from 280 m depth. ALD-26-187DEXT: 934.00 m of 0.37% CuEq1 from 324 m depth. ALD-26-180EXT: 895 m of 0.28% CuEq1 from 496 m depth. ALD-26-259: 513 m of 0.47% CuEq1 from 924 m depth, including 59 m of 0.62% CuEq1 from 1,378 m depth. Table 1 below shows detailed assays for all seven holes. The grades are uncut. CuEq values were calculated using copper, gold, silver, and molybdenum. Metal prices utilized for the calculations are Cu = USD 3.00/lb, Au = USD 1,400/oz, Ag = USD 18/oz, and Mo = USD 10/lb. Recoveries used for the supporting metals found in the CuEq equation are as follows: Au = 50%, Ag = 51%, (based on historical metallurgical test work) and Mo = 70% (benchmarking from similar deposits). The formula utilized to calculate equivalent values is CuEq % = Cu % + (Au g/t 0.34025) + (Ag g/t 0.00446) + (Mo ppm 0.00023). EXT indicates the hole was extended from a previously drilled hole. Intervals represent true thickness of the deposit. The scientific and technical data contained in this news release has been reviewed and approved by Dr. Kevin B. Heather, B.Sc. (Hons), M.Sc, Ph.D, FAusIMM, FGS, Chief Geological Officer and director of Aldebaran, who serves as the qualified person (QP) under the definitions of National Instrument 43-101. Altar follows systematic and rigorous sampling and analytical protocols which meet and exceed industry standards. These protocols are summarized below and are available on the Aldebaran website. All drill holes are diamond core holes with PQ, HQ or NQ core diameters. Drill core is collected at the drill site where recovery and RQD (Rock Quality Designation) measurements are taken before the core is boxed and transported to the Altar camp facilities, a short distance away, where the whole core is photographed under more optimum lighting conditions and geological quick log is produced. The whole-core is then marked and sampled into geological defined, systematic 1- to 2-metre sample intervals, unless the geologist determines the presence of an important geological contact, which should not be crossed. The whole-core is then cut-in-half with a diamond saw blade, with half the sample retained in the core box for future reference and the other half placed into a pre-labelled plastic bag, sealed with a two plastic security zip ties, and labeled with a unique sample number. The bagged samples are then placed into larger plastic sacks, and those sacks are sealed with another plastic security zip tie and labelled for shipment. The sacks are then placed onto wooden pallets and wrapped in plastic shrink-wrap and stored in a secure area pending shipment to a certified ALS laboratory sample preparation facility located in Mendoza, Argentina, where the samples are dried, crushed, and pulverized. The resulting sample pulps are sent by batch to the ALS laboratory in Lima for geochemical assay analysis, including a 30g fire assay with an atomic absorption (AA) finish analysis for gold and a full multi-acid digestion (4-acid) with ICP-AES analysis for other elements. Samples with results that exceed maximum detection values for gold are re-analyzed by fire assay with a gravimetric finish and other elements of interest are re-analyzed using precise ore-grade ICP analytical techniques. Aldebaran independently inserts certified control standards (Super Certified Reference Materials (SCRM’s), coarse field blanks, and duplicates into the sample stream to monitor data quality. These control samples represent 10-12% of the total samples submitted and are inserted “blindly” to the laboratory in the sample sequence prior to departure from the Aldebaran facilities.
