technical report summary technical

"Publication of an updated Technical Report Summary ("TRS") by Intrepid Potash"

A technical report summary is a concise overview of detailed research or analysis about a particular subject, highlighting key findings and important information. For investors, it provides a quick understanding of complex data or technical details, helping them make informed decisions without needing to review the entire report. Think of it as a brief map that points out the most essential parts of a larger, detailed document.

battery-grade lithium carbonate technical

"5,000 tons per year of battery-grade lithium carbonate from an industrial brine"

Battery-grade lithium carbonate is a highly pure chemical compound used as a key ingredient in the manufacture of lithium-ion battery cathodes and electrolytes. Think of it as the flour in a baking recipe: its quality affects the final product’s performance and safety. Investors care because its availability, purity and price influence battery makers’ costs, electric vehicle and storage supply chains, and therefore the revenue and margins of companies across the clean-energy ecosystem.

lithium chloride technical

"combining the extraction of lithium chloride with on-site conversion"

Lithium chloride is a simple chemical salt made from lithium and chlorine that appears as a white, water‑soluble solid used in laboratory work and various industrial processes. It matters to investors because it is part of the broader lithium supply chain—used to make lithium metal and specialty chemicals—so changes in its availability, production costs or demand can signal supply pressures or cost shifts for battery makers and other companies relying on lithium, similar to a connector piece that affects a whole assembly line.

industrial brine technical

"from an industrial brine by-product stream at Intrepid's Potash facility"

Industrial brine is highly salty water used as a raw material or working fluid in manufacturing and resource extraction, from cooling and de-icing to chemical processing and mineral recovery. For investors it matters because control of brine sources and treatment can be a steady revenue stream or a bottleneck: like owning a reliable water supply for a factory, access to and cost of brine affect production, regulatory exposure, and margins in industries such as chemicals, mining, and utilities.

CANONSBURG, Pa., March 4, 2026 /PRNewswire/ -- Publication of an updated Technical Report Summary ("TRS") by Intrepid Potash, Inc. (NYSE:IPI) has confirmed the long-term viability of the White Silver Lithium Project, which will recover 5,000 tons per year of battery-grade lithium carbonate from an industrial brine by-product stream at Intrepid's Potash facility in Wendover, Utah.

On completion, this will be the first project in the USA to deliver high-purity lithium at scale using by-product brine from an existing industrial process (potash).

While much of lithium used for battery production in the USA is extracted in Latin America and refined in East Asia, this project will pioneer a new, fully domestic source of battery raw materials for a new generation of electrification. This project is notable in combining the extraction of lithium chloride with on-site conversion (or refining) to battery-grade (>99.5%) lithium carbonate. Design, engineering and execution of the White Silver Lithium Project is taking place under a joint development agreement comprising Intrepid Potash, Aquatech and Adionics.

The project is being developed by White Silver LLC, a wholly owned subsidiary of Aquatech. Aquatech combines bespoke process development, modular system delivery, and lifecycle performance considerations to ensure project bankability and speed of execution. The modular and scalable nature of Aquatech's PEARL™ process technology platform underpins this effort by supporting capital efficiency and a long-term performance guarantee.

"This milestone reflects the strength of a developer-led approach that integrates resource understanding, process technology, and execution discipline," said Devesh Sharma, CEO at Aquatech. "By applying our PEARL™ technology platform and decades of experience delivering complex water and process projects, we are helping to shape a bankable pathway for domestic lithium production from industrial brine."

About White Silver

White Silver LLC is a project company established by Aquatech to develop a five thousand metric ton per year lithium carbonate processing facility in Wendover, Utah, in collaboration with Intrepid Potash and Adionics via a Joint Development Agreement. This project will strengthen domestic critical mineral supply chains while setting new benchmarks for cost, sustainability, and reliability in U.S. lithium production.

Aquatech will design, build and operate the facility, leveraging its PEARL™ full–flow–sheet process technology platform along with Adionics' direct lithium extraction (DLE) technology.

The estimated measured and indicated lithium carbonate equivalent (LCE) mineral resources total approximately 119,000 tons. However, given the recharging nature of the shallow aquifer and quasi-infinite deep brine aquifer, the brine mineral resources can theoretically be produced in perpetuity.
