Azzuro Confirms High-Grade Copper-Gold Zones at Red Hill Project in Mongolia
Azzuro Resources has reported robust high-grade copper-gold-zinc-silver mineralisation from its 2026 drilling at the Red Hill VMS Project, with assays confirming thicker and richer sulphide zones than previous drilling. Shallow gold zones extending over 600 metres add to the project's exploration upside.
- MU2603 drillhole intersects 21.45m at 1.70% copper and 0.85 g/t gold
- Higher copper grades than 2025 due diligence drilling confirmed
- Shallow gold mineralisation extends over 600m strike north of VMS system
- 2026 drilling program fully funded with further assays pending
- Integrated geophysical data to refine future exploration targets
Robust High-Grade Copper-Gold Intercepts at Red Hill
Azzuro Resources (ASX:AZ9) has delivered a second tranche of assay results from its 2026 drilling campaign at the Red Hill Copper-Gold Volcanogenic Massive Sulphide (VMS) Project in Mongolia, revealing significant high-grade mineralisation that surpasses previous benchmarks. Drillhole MU2603 notably intersected 21.45 metres grading 1.70% copper, 0.85 grams per tonne gold, 16.86 grams per tonne silver, and 0.21% zinc from 83.2 metres, including a standout 8 metres at 3.27% copper and 1.04 g/t gold. This intercept confirms a copper-rich massive sulphide zone with substantially higher copper tenor than the 2025 due diligence hole MU2502, reinforcing the project's potential for a substantial VMS system.
Expanding Shallow Gold Zones Bolster Exploration Potential
Beyond the massive sulphide lens, Azzuro's reverse circulation holes MURC02 and MURC03 have confirmed shallow gold mineralisation extending over a strike length of approximately 600 metres north of the VMS system. MURC02 returned 5 metres at 0.63 g/t gold from just 5 metres depth, while MURC03 hit 9 metres at 0.59 g/t gold and 4.17 g/t silver from surface. These results suggest a broad, surface-traceable gold zone that could materially enhance the overall value proposition of Red Hill. Meanwhile, MU2602 corroborated additional shallow copper and gold mineralisation, including 18.25 metres at 0.67% copper and 0.16 g/t gold from 68.75 metres.
Fully Funded Program and Integrated Geophysical Approach
The 2026 exploration program at Red Hill is fully funded, positioning Azzuro to sustain a steady flow of news as it advances the project. Pending assay results for nine additional drillholes are expected shortly, alongside integrated geophysical interpretations combining downhole electromagnetic surveys, gravity, resistivity, and chargeability data. This integrated approach aims to refine targeting and guide subsequent drilling phases, including follow-up on the massive sulphide system and near-surface gold-silver and gold-copper zones. The company also plans to report on the Copper Ridge diamond drillhole CRS05 and initial 3D IP geophysical survey results from the Oval Cu-Ni area.
Contextualising the Red Hill Discovery
Located in southwestern Mongolia, the Red Hill project is interpreted as a felsic VMS deposit hosted in dacitic and rhyolitic volcanics with associated black schists. The mineralisation comprises a steeply north-dipping massive sulphide lens rich in copper, gold, silver, and zinc, folded by multiple deformations. The recent drilling results build on earlier successes, confirming the continuity and up-dip extension of the massive sulphide zone and the presence of a broad shallow gold zone. The project benefits from a 30-year mining licence secured in 2015, with Azzuro having acquired 100% ownership in April 2026.
Geological and Technical Rigour Underpinning Results
The drilling program combines diamond core and reverse circulation techniques, with HQ-sized core samples oriented and assayed by industry-standard laboratories. Quality control protocols, including certified reference materials, blanks, and duplicates, ensure data reliability. While true widths of mineralisation remain undetermined, downhole intervals are interpreted to be greater than true widths for the massive sulphide lens, and similar to true widths for the shallow oxide gold-silver zone. The comprehensive geological logging and integration with geophysical data underpin Azzuro's confidence in delineating the system's scale.
Bottom Line?
Azzuro’s latest assays at Red Hill strengthen the case for a substantial high-grade copper-gold VMS system, but upcoming results and geophysical integration will be critical to define the project's true scale and economic potential.
Questions in the middle?
- How will pending assay results influence the interpretation of Red Hill's mineralisation continuity?
- What impact will integrated geophysical data have on refining drilling targets and resource estimation?
- Could the extensive shallow gold zone north of the VMS system represent a standalone exploration target?
