Azzuro Resources has reported a second batch of assay results from its 2026 drilling programme at the Red Hill copper-gold project in southwestern Mongolia, with hole MU2603 returning 21.45 metres at 1.70% copper, 0.85 grams per tonne gold, 16.86 grams per tonne silver and 0.21% zinc from 83.2 metres — confirming a thick massive sulphide zone with higher copper grades than the comparable 2025 due diligence hole drilled up-dip from the same system.
The interval includes a higher-grade core of 8.0 metres at 3.27% copper, 1.04 grams gold, 18.09 grams silver and 0.20% zinc from 95 metres. The hole also returned subsidiary mineralised intervals beneath the main lens, including a semi-massive sulphide vein grading 2.67% copper from 126.95 metres, suggesting the system extends beyond a single narrow intercept.
MU2602, drilled to test the eastern extension beneath a surface hydrothermal breccia, returned an 18.25-metre copper zone averaging 0.67% copper from 68.75 metres, including a four-metre high-grade sub-interval at 1.51% copper, alongside a separate shallow gold zone of 12 metres averaging 0.74 grams gold from 19 metres and a three-metre interval at 1.58 grams gold.
Reverse circulation drilling north of the main volcanogenic massive sulphide system is defining a near-surface oxide gold-silver zone that Azzuro says may extend across approximately 600 metres of strike. Two of three RC holes returned gold intersections: MURC02 hit 5.0 metres at 0.63 grams gold from five metres, and MURC03 returned 9.0 metres at 0.59 grams gold and 4.17 grams silver from surface.
Managing Director Gan-Ochir Zunduisuren said the MU2603 results exceeded expectations and reinforced confidence in a substantial high-grade copper-gold VMS system, while the shallow gold zone adds meaningful exploration optionality. Nine additional diamond holes remain pending, with assays expected in July alongside integration of geology, drilling and geophysical datasets including DHEM, gravity, resistivity and chargeability results.
Azzuro completed its 100% acquisition of the Red Hill project in April 2026. The mining licence covers 79.14 hectares and is valid to 2045.
