en.Wedoany.com Reported - Azzuro Resources has encountered high-grade massive sulfide mineralization at its Red Hill copper-gold VMS project in Mongolia, with some drill hole assays exceeding expectations.
Hole MU2603 intersected 21.45 meters at 1.70% copper, 0.85 g/t gold, 16.86 g/t silver, and 0.21% zinc from 83.2 meters depth. Within this, an 8-meter section from 95 meters depth returned 3.27% copper, 1.04 g/t gold, 18.09 g/t silver, and 0.20% zinc. Azzuro Resources (ASX:AZ9) stated that these assays reconfirm the visually observed copper-rich massive sulfides in the hole, with copper grades significantly higher than those from last year's due diligence hole MU2502.
Hole MU2603 was designed to follow the up-dip extension of the massive sulfides in MU2502, intersecting the mineralization zone approximately 75 to 80 meters above the previous intercept. Additionally, the hole encountered a 0.45-meter semi-massive sulfide vein at 126.95 meters depth, grading 2.67% copper, 0.63 g/t gold, 5.9 g/t silver, and 0.68% zinc.
Managing Director Gan-Ochir Zunduisuren stated that the assays from MU2603 exceeded expectations. He noted that the significant increase in copper grades up-dip from last year's due diligence hole further strengthens the company's belief in a large-scale, high-grade copper-gold VMS system at Red Hill.
The second diamond drill hole, MU2602, tested the eastern extension of mineralization beneath hematite-limonite hydrothermal breccia, further expanding the scale of Red Hill. This hole intersected 18.25 meters at 0.67% copper, 0.16 g/t gold, and 0.15% zinc from 68.75 meters depth, including a 4-meter section from 78 meters depth grading 1.51% copper, 0.34 g/t gold, and 0.19% zinc. The hole also intersected 4.3 meters at 0.77% copper, 0.35 g/t gold, and 0.36% zinc from 90 meters depth. Additionally, the hole revealed a shallow gold zone, with a 12-meter section from 19 meters depth grading 0.74 g/t gold, including a 3-meter section from 27 meters depth grading 1.58 g/t gold.
The gold prospectivity has also been enhanced. Assays from three reverse circulation (RC) holes tested the lateral continuity of near-surface oxidized gold-silver mineralization north of the Red Hill VMS system. Hole MURC02 returned a 5-meter section grading 0.63 g/t gold from 5 meters depth, located approximately 335 meters west-northwest of MU2501. Hole MURC03 returned a 9-meter section grading 0.59 g/t gold and 4.17 g/t silver from surface, located approximately 96 meters east-southeast of MU2501. These results outline a gold zone traceable at surface, potentially extending over 600 meters of strike length north of the VMS system. The northernmost RC hole, MURC01, only returned narrow, low-grade copper intervals and did not confirm the continuity of the shallow gold zone at that location.
Red Hill (formerly Maikhan Uul) is located in southwestern Mongolia and is a 100%-owned copper-gold project by Azzuro, considered prospective for volcanogenic massive sulfide mineralization. The project hosts multiple untested geophysical and geochemical anomalies within favorable volcanic stratigraphy, highlighting further discovery potential. Azzuro expects to receive assays for the remaining nine holes at Red Hill in July, along with results from the Copper Ridge hole CRS05 and initial 3D IP data from the Oval copper-nickel target. The company will integrate drilling, geological, DHEM, gravity, resistivity, and chargeability data into the next round of targets, covering massive sulfide systems, near-surface gold-silver zones, and shallow copper-gold prospects. Zunduisuren stated that the fully funded 2026 program will maintain a steady flow of information, and Azzuro is committed to defining the scale of the system.
