Uranium, a key element powering nuclear energy and shaping the future of clean energy solutions, is found in vast deposits across the globe. As nuclear power gains traction as a low-carbon energy source, understanding the geography of uranium resources is essential for industry stakeholders and policymakers. This article delves into the ten largest uranium deposits and projects worldwide.
The Top Uranium Deposits & Projects by Size
Olympic Dam, Australia – Owned by BHP Group Ltd, Olympic Dam is the largest uranium deposit globally, with a staggering 5,706 million pounds of uranium classified as Reserves and Resources (R&R). Known for its polymetallic riches, this project also produces significant amounts of copper, gold, and silver.
Viken, Sweden – Managed by District Metals Corp, the Viken deposit is a polymetallic black shale-hosted type deposit. It contains uranium as well as other valuable metals like vanadium, molybdenum, and nickel, making it a multi-resource asset. It boasts a historic resource if 1,038 M lbs of uranium (Inferred Resources). Its potential for large-scale development makes it a noteworthy European asset in the uranium sector.
Elkon, Russia – Operated by JSC Atomredmetzoloto, the Elkon deposit holds 928 M lbs of uranium (R&R). Located in Siberia, it supports Russia's nuclear energy and export goals. Despite its remote location, it's strategically vital for global uranium markets and Russia’s energy security.
Häggån, Sweden – Aura Energy Ltd's Häggån project is another polymetallic black shale-hosted deposit and is located near the Viken deposit. It contains an inferred 800 M lbs of uranium, making it one of the largest undeveloped uranium resources globally.
Kvanefjeld, Greenland – The Kvanefjeld deposit is one of the world's largest undeveloped rare earth element (REE) and uranium resources. it contains substantial resources of REEs like neodymium and praseodymium, critical for green technologies. Kvanefjeld also hosts significant uranium reserves, 593 M lbs of uranium (R&R). Its development is central to debates about Greenland's mining policies and its global role in supplying strategic minerals.
Imouraren, Niger – Orano SA operates the Imouraren deposit, with 520 M lbs of uranium (R&R). Located in northern Niger, the Imouraren deposit is a key asset in the country's uranium industry. Planned for large-scale, low-grade open-pit mining, its development has been delayed by challenging market conditions. However, the project remains vital to both global uranium supply and Niger’s economy, with substantial potential for future production.
Husab, Namibia – The Husab project, owned by Swakop Uranium, contains 478 M lbs of uranium (R&R) and is a major open-pit mining operation. It plays a crucial role in Namibia's economy, solidifying the country's position as a top uranium producer, with output fueling nuclear power plants.
McArthur River, Canada – Cameco Corp’s McArthur River deposit features 381 M lbs of uranium (P&P). It is the world's largest high-grade uranium mine. Located in northern Saskatchewan, it holds some of the richest uranium ore globally, with grades significantly higher than the industry average. Discovered in 1988 and in production since 1999, McArthur River has a production capacity of 18 million pounds of uranium annually.
Itataia, Brazil – A privately owned project, Itataia holds 314 M lbs of uranium (R&R). The The owner aims to produce both uranium and phosphate, which are key for energy and agriculture. It's significant for Brazil's nuclear energy ambitions and fertilizer industry, as the project will also produce phosphate-based fertilizers.
Inkai, Kazakhstan – Jointly operated by Cameco and Kazatomprom, the Inkai project contains 262 M lbs of uranium (P&P). Kazakhstan remains a global leader in uranium production, with Inkai as one of its flagship assets. It is a roll-front type deposit, which means that the uranium is concentrated in a crescent-shaped zone within permeable sandstone.
