Prairie Lithium Advances Largest North American DLE Unit Testing Ahead of Saskatchewan Launch

Largest DLE Unit in North America Enters Final Testing

Prairie Lithium (ASX:PL9) has taken a significant step toward commercial lithium production with its commercial-scale Direct Lithium Extraction (DLE) unit entering Factory Acceptance Testing (FAT). This four-column unit represents the largest DLE installation built in North America and is a key milestone before its deployment to the company’s Phase 1 production facility in Saskatchewan, Canada.

The scale of Prairie’s DLE unit dwarfs the single-column system deployed by Standard Lithium in Arkansas, which began operations in March 2024 and has since processed approximately one million barrels of brine with lithium recovery exceeding 95%. Prairie’s four-column setup aims to build on this proven technology at roughly four times the scale, positioning the company to accelerate its production ramp-up.

Binding Offtake and Strategic Equipment Partnership Reduce Capital Burden

Phase 1 production is underpinned by a binding offtake agreement with South Korea’s Hydro Lithium, securing 100% of the initial 150 tonnes per annum lithium carbonate equivalent output. Hydro Lithium is also contributing approximately A$10 million worth of proprietary refining equipment, which it will operate on-site, significantly lowering Prairie’s upfront capital requirements and supporting a leaner development model.

This strategic partnership not only ensures a clear revenue pathway but also validates Prairie’s approach to producing an upgraded intermediate lithium product suitable for downstream battery-grade conversion. The collaboration echoes earlier announcements where Hydro Lithium’s involvement was highlighted as a cornerstone of Prairie’s Phase 1 development strategy.

Installation and Commissioning Timeline Targets Q4 2026

Following successful FAT completion, the DLE unit will be transported and installed at the Saskatchewan site, where construction of the Phase 1 facility continues apace. Commissioning remains targeted for Q4 2026, with initial lithium production expected to commence shortly thereafter, marking Prairie’s transition from development to revenue generation.

Prairie plans to continue optimising the DLE unit’s operational performance post-commissioning, focusing on lithium recovery rates and contaminant rejection, while evaluating expansion opportunities through its scalable pad-by-pad development model. This approach aims to leverage existing regional infrastructure and the mining-friendly jurisdiction of Saskatchewan to efficiently scale production.

Building on Momentum from Pad Construction and Offtake Deals

The current FAT milestone complements recent progress at Prairie’s Pad #1 site, where foundation and vertical building works have advanced alongside SaskPower’s installation of powerlines supplying low-cost grid electricity. These developments support the company’s target to deliver first production in Q4 2026 under the binding Hydro Lithium offtake agreement, which also includes the strategic equipment contribution.

These operational strides follow a series of announcements detailing Prairie’s binding offtake agreement and strategic collaboration with Hydro Lithium, as well as the company’s accelerated plant build featuring prefabricated construction methods designed to mitigate weather risks and expedite delivery.
