The 2026 copper supply race has reached a new level of intensity in Central Asia. Azzuro Resources (ASX: AZ9) has reported a headline-grabbing drill intercept from its Red Hill Volcanogenic Massive Sulphide (VMS) Project in Mongolia, returning 11.94% copper and 1.63 g/t gold over a 1.6-meter interval in hole MU2605.
The high-grade hit, located within a massive sulphide lens, comes at a critical juncture for the global market. As structural deficits loom and the industry grapples with a significant copper price forecast 2026 driven by AI data centers and electrification, Azzuro’s results suggest that Mongolia’s copper story is evolving beyond the massive porphyry systems of Oyu Tolgoi.
For mining industry professionals and those scouting for critical minerals stocks to buy 2026, the Red Hill discovery highlights the potential for high-value, high-grade VMS deposits in under-explored belts.
Deep Dive: The MU2605 High-Grade Core
The latest drilling at Red Hill has significantly de-risked the geological model for the project. Hole MU2605 intersected the massive sulphide lens from 127.2 meters downhole. The results are some of the highest copper grades reported in Mongolia’s junior exploration sector in recent years:
- 1.6m @ 11.94% Cu, 1.63 g/t Au, 30.13 g/t Ag, and 0.84% Zn
- Broader intercept: 7.0m @ 0.80% Cu and 0.19 g/t Au from 75.0m
The visual logging of MU2605 confirms the presence of primary chalcopyrite, making up approximately 41.6% of the basal interval. This suggests a clean, high-grade mineralogy that is often characteristic of premier VMS districts globally.
High-grade copper mineralization often presents as distinct massive sulphide lenses.
Expanding the Footprint: 550 Meters and Counting
One of the most significant takeaways from the recent campaign is the expansion of the mineralized strike. Azzuro has now confirmed that the VMS system extends over 550 meters and remains open in all directions.
Parallel to the copper-rich core, the company is also defining a near-surface gold corridor that has expanded to approximately 600 meters in length. The presence of both copper-rich massive sulphides and a distinct gold-silver-zinc halo points to a robust, zoned mineralizing system typical of high-quality VMS clusters.

Mongolia’s 2026 Copper Outlook
Mongolia is increasingly viewed as a frontline jurisdiction in the global search for critical minerals. While the country has long been anchored by the Oyu Tolgoi underground ramp-up, the 2026 landscape is shifting.
The government’s pivot from coal toward copper value-addition is evidenced by the planned commissioning of the Khanbogd copper smelter later this year. This infrastructure build-out is expected to lower logistics costs for regional explorers like Azzuro, transforming the economics of smaller, high-grade deposits that can feed into a centralized processing hub.
However, the investment climate remains a "moderate" play. While the resource base is unquestioned, operators must navigate a regulatory environment that is still maturing. The opening of the Investor Protection Center in early 2026 was a significant step toward providing the fiscal predictability required for multi-year exploration programs.
Strategic infrastructure in Mongolia is expanding to support the next generation of copper discoveries.
The 2026 Copper Deficit Impact
The timing of Azzuro’s high-grade hits coincides with a tightening global market. Analysts at J.P. Morgan and Morgan Stanley have projected refined copper deficits ranging from 330,000 to 600,000 tonnes for 2026.
This "copper deficit impact 2026" is largely driven by three factors:
- AI Data Center Build-out: Hyperscale facilities are projected to consume nearly 475,000 tonnes of copper this year alone.
- Mine Disruptions: Continued operational challenges at legacy tier-1 assets in South America and the DRC have constrained concentrate supply.
- Underinvestment: A decade of low exploration spending has left the industry without a "ready" pipeline of new mines.
In this environment, high-grade discoveries in stable mining districts (Red Hill is on a granted mining license) become highly sought after by majors looking to replace depleting reserves.
Strategic Roadmap: What’s Next for Red Hill?
Azzuro Resources is moving quickly to capitalize on the MU2605 momentum. The company has outlined a clear operational schedule for the remainder of 2026:
- August 2026: A 3D Induced Polarization (IP) geophysical survey will commence at the Oval Cu-Ni area, located just 8 km from Red Hill.
- Q3 2026: Initial metallurgical testing is scheduled to begin. This will be a critical milestone for determining the potential recovery rates and concentrate quality.
- Ongoing Drilling: Exploration will continue to test the 550m strike extension and target deeper massive sulphide targets identified by geophysics.
Modern data integration is essential for managing multi-rig exploration programs in remote regions.
Journalistic Perspective: The VMS Opportunity
While porphyry deposits provide the scale, VMS deposits like Red Hill provide the "grade punch" that can significantly boost project internal rates of return (IRR). Azzuro’s ability to hit nearly 12% copper at relatively shallow depths (sub-150 meters) suggests that the Red Hill system could be part of a larger, high-value cluster.
In the broader context of mining news, Azzuro's success is a reminder that the energy transition will be won by those who find the highest-quality ore in jurisdictions willing to build the necessary processing infrastructure. Mongolia, with its 100-year mining legacy and renewed focus on copper, is positioning itself to be that jurisdiction.
As the industry moves toward the latter half of 2026, the results from the upcoming IP survey and metallurgical tests will likely determine if Red Hill is a standalone success or the precursor to a major new Mongolian copper-gold district.
