Uzbekistan’s In-Situ Uranium Recovery Technology Reshapes Global Supply Dynamics

[[PRRS_LINK_1]] is emerging as a key pillar of the global nuclear fuel supply chain, with Uzbekistan accelerating uranium output through advanced in-situ recovery (ISR) technology that is reshaping how deposits are mined, processed, and brought to market. The country, already the world’s fifth-largest uranium producer, is increasingly relying on technologically advanced extraction methods that significantly reduce costs and environmental disruption while unlocking large sandstone-hosted resources in the Central Kyzylkum Desert.

Uzbekistan strengthens position in global uranium supply

Uzbekistan produced an estimated 4,000 tonnes of uranium in 2024, according to the World Nuclear Association, cementing its place behind [[PRRS_LINK_2]], [[PRRS_LINK_3]], [[PRRS_LINK_4]] and [[PRRS_LINK_5]]. Production is led by state-owned group Navoiyuran, the world’s sixth-largest uranium producer, which controls a resource base of around 151,100 tonnes of uranium across 43 deposits, including 96,600 tonnes of JORC-compliant reserves. Output is rising rapidly. In 2025, Navoiyuran produced 7,000 tonnes of natural uranium, supported by expansion across key deposits and a national strategy targeting higher mining and processing capacity through 2030.

ISR technology becomes the backbone of production

The defining feature of [[PRRS_LINK_6]] uranium industry is its reliance on in-situ recovery (ISR), a method that eliminates the need for traditional open-pit or underground mining. Instead of excavating ore, ISR injects oxygenated solutions into uranium-bearing sandstone formations, dissolving the metal underground before pumping it back to surface for processing into yellowcake. This approach is particularly effective in the Central Kyzylkum Desert, where geological conditions allow controlled fluid movement through permeable sandstone layers.

Key advantages of ISR include:

• Minimal surface disturbance
• Lower capital and operating costs
• Flexible production scaling
• Reduced waste generation

At Navoiyuran’s Qizilkok deposit, ISR operations moved from pilot phase in December 2024 to commercial production in April 2026, reflecting a structured ramp-up model typical of modern uranium projects.

Low-reagent oxygen technology cuts costs and boosts efficiency

A central innovation in Uzbekistan’s uranium strategy is proprietary low-reagent oxygen ISR [[PRRS_LINK_7]], which replaces traditional acid-heavy leaching systems. Instead of relying on large volumes of sulfuric acid, the system uses gaseous oxygen as the primary oxidant, significantly reducing chemical consumption while improving dissolution efficiency.

According to operational data, the technology delivers:

• 2–3x lower production costs
• Higher uranium recovery rates
• Reduced [[PRRS_LINK_8]] footprint
• Lower reliance on imported reagents

The Qizilkok deposit, which holds around 10,900 tonnes of [[PRRS_LINK_9]] resources, has become the flagship site for this method. It supports an estimated 15-year mine life and annual output of roughly 1,200 tonnes of uranium, accounting for a significant share of Navoiyuran’s production base.

Key deposits underpin production growth

Uzbekistan’s uranium output is driven by a small number of large-scale ISR-compatible deposits.

Among the most important are:

• Sugrali deposit – ~20,800 tU reserves
• Uchkuduk deposit – ~14,800 tU reserves
• Qizilkok deposit – ~9,400 tU reserves

The Qizilkok project integrates four licence blocks—Amantau, Myutenbay, Qizilkok and Yuzhny—into a unified production system, enabling shared infrastructure and more efficient extraction. The broader portfolio of 151,100 tonnes of uranium resources provides long-term optionality for sustained production growth and potential expansion beyond current mine plans.

Economics driven by low-cost ISR production

Uzbekistan’s uranium industry benefits from one of the lowest-cost production models globally, driven by ISR efficiency and minimal surface infrastructure requirements.

Key economic advantages include:

• 2–3x lower production costs versus conventional mining
• Reduced capital intensity
• Scalable output aligned with market demand
• High utilisation of existing well-field infrastructure

At Qizilkok alone, production represents about 17% of Navoiyuran’s 2025 output, demonstrating how individual ISR assets can materially shift national production levels. The long-term mine life and low-cost structure also enhance Uzbekistan’s competitiveness in global uranium markets, particularly as nuclear energy demand rises.

Environmental and operational considerations

ISR technology introduces a different [[PRRS_LINK_10]] profile compared with conventional mining.

While surface disruption is minimal, the method requires strict control of groundwater systems, including:

• Continuous aquifer monitoring
• Chemical containment within ore zones
• Well integrity management
• Post-operation restoration planning

The low-reagent oxygen system further reduces environmental risk by limiting chemical usage and lowering contamination potential. The arid conditions of the Central Kyzylkum Desert also reduce surface water risks, although groundwater management remains critical throughout the operational lifecycle.

Strategic importance in global nuclear supply chains

Global uranium demand is expected to rise as countries expand nuclear capacity for energy security and decarbonisation goals. Against this backdrop, Uzbekistan is positioning itself as a stable and scalable supplier.

Key strategic factors include:

• Large, long-life resource base (151,100 tU)
• Rapid production growth trajectory
• Low-cost ISR technology advantage
• Increasing integration into global fuel supply chains

The country’s expansion strengthens supply diversification away from traditional producers and supports long-term energy security for nuclear utilities worldwide.
