The dawn of the American lithium industry has arrived in Southern Arkansas. With this opportunity comes a water problem — and we have the solution.

Hidden in Arkansas’s Smackover Formation is a generational opportunity. Not in the form of gold or diamonds, but lithium. The technological cornerstone of this revolution is Direct Lithium Extraction (DLE), but capitalizing on this boom hinges on efficiently and sustainably managing the complete water lifecycle, including pre-treating challenging brines, processing massive volumes, and ensuring environmentally sound reinjection.

Fortunately, there is an award-winning team of water treatment experts with patented technology and a holistic portfolio of services designed to harness Arkansas's lithium future sustainably and profitably. And the best part: We have called Arkansas home for generations.

We are Menen Group, and we are here for good.

DLE Market CAGR

  • The Smackover Formation contains lithium dissolved in hot, high-salinity brine trapped in Jurassic-era limestone. With concentrations exceeding 400 mg/L and recent discoveries showing up to 671 mg/L, these grades rival South America's "Lithium Triangle."

    Unlike arid regions, Arkansas doesn't face water scarcity issues, making closed-loop water management systems more feasible and sustainable.

  • DLE technologies offer a faster, more efficient alternative to traditional solar evaporation. These advanced water treatment processes can produce lithium in hours instead of months, with a much smaller environmental footprint.

  • Success depends on managing complex water lifecycles: pre-treating challenging brines, processing massive volumes, and ensuring environmentally sound reinjection. This creates opportunities for both primary lithium extraction and secondary municipal infrastructure growth.

Key Takeaways

The Smackover Formation

World-Class Resource: The Smackover Formation contains 5-19M metric tons of lithium with high concentrations comparable to South America.

Technology-Driven: Extraction relies on Direct Lithium Extraction (DLE), advanced water treatment technologies faster and more sustainable than traditional methods.

Water Challenge at Core: Success depends on managing complex water lifecycles, processing massive volumes, and ensuring environmentally sound reinjection.

Dual Opportunity: Creates demand for both primary lithium extraction solutions and secondary municipal infrastructure growth.

"The Smackover is sort of the right time, the right place, and the right geology combined."

It all starts with cost-effective, sustainable extraction and concentration — delivered by WATR™ Labs MPVD Technology.

Patented Innovation

WATR™ Labs MPVD Technology

Multi-phase Vacuum Desalination (MPVD). A breakthrough solution for high-salinity brine treatment, protected by U.S. Patent No. 11,878,919 B1.

How MPVD Works

MPVD leverages reduced pressure to lower the boiling point of brine, enabling efficient water vapor separation at lower temperatures than traditional thermal methods. This significantly reduces energy consumption while achieving higher concentration factors.

The "multi-phase" staged process prevents premature salt precipitation and scaling, common failure points in other high-salinity treatment systems.

  • Reduced temperature operation saves energy costs

  • Superior concentration factors vs. competitors

  • Smaller footprint than evaporation ponds

  • Increases lithium concentration before primary DLE

  • Concentrates dilute lithium solutions to high-purity product

  • Arkansas-developed technology for worldwide deployment

  • Enhanced Recovery

    MPVD significantly increases overall lithium recovery rates by efficiently concentrating post-DLE solutions, maximizing sellable product from the same brine volume.

    Higher purity lithium concentrate

    Premium pricing potential

    Reduced refining costs

  • Cost Efficiency

    Multi-faceted cost reduction through lower energy requirements, compact design, and water recovery capabilities

    Reduced OPEX through energy savings

    Lower CAPEX with smaller footprint

    Water reuse reduces costs

  • Sustainability

    Zero Liquid Discharge capability positions projects as leaders in sustainable resource extraction with minimal environmental impact.

    ✔ Maximum water recovery

    ✔ Minimal waste generation

    ✔ Enhanced social license
