Amaroq Ltd. Unveils Major Mineral Potential at Minturn Prospect

Amaroq Ltd., an independent mine development company focused on Greenland’s mineral resources, has released an extensive update confirming high-grade iron and the potential for copper and gold mineralisation at its Minturn prospect in Northwest Greenland. The results from the 2025 field exploration campaign show promising geological indicators that suggest Minturn could be a large-scale Iron Oxide Copper Gold (IOCG) system — a class of mineral deposit known worldwide for both its size and economic value.

Background: Strategic Importance of the Minturn Project

The Minturn prospect lies north of the US Pituffik Space Base in the remote Inglefield Land region of Greenland. Historically, this area was explored by Greenland’s government entity NunaMinerals in 2010, which identified a large magnetic anomaly and high-grade iron samples but interpreted the finding mainly as a vanadium-rich iron deposit. Amaroq’s reinterpretation of existing data using modern geophysical techniques has revealed that the system may be much more complex and mineralised than previously believed.

Reprocessing of historic geophysical datasets has enabled Amaroq to build a new geological model showing a significant mineralised system across an ~80 km linear zone — a scale that supports the possibility of a Kiruna-style IOCG deposit. This type of system typically includes high concentrations of iron, copper, and gold, making it an exciting target for exploration.

Key Results from the 2025 Field Campaign

Exceptional Iron Grades

Surface sampling during the 2025 exploration campaign returned remarkably high iron (Fe) grades, with some samples reaching up to 69.5% Fe. Multiple samples registered between 66% and 69% Fe, indicating a robust iron-oxide core area within the system. These grades are significantly high and demonstrate the prospect’s potential to host iron mineralisation that could be suitable for direct shipping ore (DSO), particularly for Direct Reduced Iron (DRI) production.

Importantly, preliminary analyses of these samples showed relatively low levels of impurities, such as silica (SiO₂), alumina (Al₂O₃), and phosphorus (P), which are beneficial for iron ore quality and future commercial production.

Copper and Gold Potential

Beyond iron, the exploration team at Minturn identified an electromagnetic (EM) anomaly running parallel to the main magnetic trend. Follow-up soil sampling over this EM target returned anomalous indications of copper — and associated elements often linked to gold mineralisation. This discovery suggests that the Minturn system could contain sulphide-rich zones with copper and potentially gold mineralisation, adding significantly to its economic potential under the IOCG model.

Geological Indicators of an IOCG System

IOCG systems are characterised by extensive iron oxide alteration, brecciation, and the presence of copper-gold mineralisation. The geological features observed at Minturn — including magnetite-rich breccia and widespread iron oxide alteration over a strike of roughly 9 km — are consistent with this deposit type. These features align with known IOCG deposits globally, which can contain tens of millions to billions of tonnes of ore.

Next Steps: 2026 Exploration Programme

Buoyed by the encouraging findings from the 2025 work, Amaroq is now planning a substantial 2026 field campaign aimed at advancing the Minturn prospect even further. The program is expected to include:

• Scouting drill holes to test copper-gold targets indicated by geophysical surveys.
• Expanded detailed geological mapping to define the geometry and extent of mineralisation.
• Ground geophysical surveys to refine targets and better understand subsurface structures.

This follow-up campaign aims to delineate the mineralised system more precisely and evaluate its economic potential as an IOCG deposit. Successful confirmation of copper and gold mineralisation at depth could transform Minturn into a flagship project in Amaroq’s strategic portfolio.

Implications for Greenland’s Mineral Future

The findings at Minturn add to Greenland’s growing reputation as a frontier for critical mineral exploration. IOCG systems are globally recognised for their value, often containing multiple commodities that are essential for modern technology and infrastructure — including iron, copper, and gold. If Minturn is confirmed as an IOCG deposit through further exploration, it would reinforce Greenland’s potential to host large, world-class mineral systems that extend beyond traditional gold resources.

Amaroq’s strategy — focused on unlocking Greenland’s rich geological potential — includes other projects across the country targeting gold, zinc, nickel, and rare earth elements. The success of Minturn could position the company as a significant contributor to the development of strategic mineral supplies in the Arctic region.

Technical and Quality Assurance Details

Surface rock samples were collected from outcrop locations and analysed by an accredited laboratory using industry-standard procedures, including multi-element analysis and fire assay methods. Soil samples were obtained from consistent B-horizon depths and processed using ionic leach techniques (ME-MS23) to detect subtle geochemical anomalies. These quality assurance and quality control (QA/QC) protocols ensure that the analytical data supporting the exploration results are reliable and robust.

Corporate Context and Forward-Looking Information

Amaroq’s principal objective is to identify, explore, and develop mineral assets in Greenland that have significant economic and strategic value. Alongside its Minturn project, the company’s portfolio includes the operating Nalunaq gold mine and other exploration targets for base and critical metals.

The press release also contains forward-looking information regarding plans for future exploration and potential outcomes. These plans are subject to risks and uncertainties, including geological, regulatory, and market risks. However, the company remains committed to advancing Minturn and other targets to unlock their resource potential.
