Azzuro Resources (ASX:AZ9) high grade copper results reported from Red Hill Project

Azzuro Resources has reported the second batch of assay results from its 2026 drilling program at the 100% owned Red Hill Copper Gold Volcanogenic Massive Sulphide Project in Mongolia.

The results comprise drillholes MU2602 and MU2603, and reverse circulation holes MURC01, MURC02 and MURC03, with further assay results from the 2026 program expected over the coming weeks.

Highlights

Drillhole MU2603 was drilled to intersect the downhole electromagnetic conductor plate modelled from drillhole MU2502 and to test an up dip extension of the massive sulphide intersected in MU2502.

The hole intersected the targeted massive sulphide approximately 75m to 80m up dip of the MU2502 intercept and returned 21.45m @ 1.70% Cu, 0.85g/t Au, 16.86g/t Ag and 0.21% Zn from 83.2m, including 8.0m @ 3.27% Cu, 1.04g/t Au, 18.09g/t Ag and 0.20% Zn from 95.0m.

The assays confirm that copper tenor in the MU2603 massive sulphide has increased significantly relative to the equivalent intercept in MU2502.

MU2602 was drilled to test the eastern extension of the mineralised system beneath a hematite limonite rich hydrothermal breccia mapped at surface.

The hole returned copper and gold mineralisation over several intervals, including 18.25m @ 0.67% Cu, 0.16g/t Au and 0.15% Zn from 68.75m, including 4.0m @ 1.51% Cu, 0.34g/t Au and 0.19% Zn from 78.0m.

The hole also returned a shallow gold zone of 12.0m @ 0.74g/t Au from 19.0m, including 3.0m @ 1.58g/t Au from 27.0m.

The company reported that the copper gold mineralisation occurs within strongly pyritic rhyolite carrying chalcopyrite veining and minor bornite.

The three reverse circulation drillholes were drilled to test the lateral continuity of the near surface oxide gold silver zone to the north of the Red Hill VMS system.

MURC02, collared approximately 335m west northwest of MU2501, returned 5.0m @ 0.63g/t Au from 5.0m, while MURC03, approximately 96m from MU2501, returned 9.0m @ 0.59g/t Au and 4.17g/t Ag from surface. Together these results confirm shallow gold mineralisation is present over a long area to the north of the VMS system, including well to the west northwest of the earlier MU2501 intercept.

The Red Hill Project, formerly known as Maikhan Uul, is located in southwestern Mongolia and is considered prospective for volcanogenic massive sulphide mineralisation, hosting multiple untested geophysical and geochemical anomalies within a favourable volcanic stratigraphy.

The company plans to integrate the geological, drilling and geophysical datasets, including DHEM, gravity, resistivity and chargeability, to refine targeting and guide the planning of further drilling at the massive sulphide system and the near surface gold silver and shallow gold copper targets.

Azzuro Managing Director Gan Ochir Zunduisuren said,

“The outstanding results from MU2603 have exceeded our expectations. The significantly higher copper grades encountered up dip from last year’s project due diligence drilling reinforce our belief that Red Hill hosts a substantial high grade copper gold VMS system with excellent potential.”

The company's next planned activities include reporting assay results for the remaining nine drillholes from the 2026 program, integrating the geological, drilling and geophysical datasets, including DHEM, gravity, resistivity and chargeability, to refine targeting and guide the planning of further drilling at the massive sulphide system and the near surface gold silver and shallow gold copper targets, reporting assay results of the Copper Ridge diamond drillhole CRS05, and reporting the initial Oval Cu Ni area geophysical survey 3D IP results.

Further assay results and integrated geophysical interpretation are expected over the coming weeks.
