LibertyStream Begins Installation and Integration of DLE Extraction and Refining Systems at Select Water Solutions' Site; Initial Production Expected Early Q2

• LibertyStream has completed site preparations and begun installing its direct lithium extraction and lithium carbonate refining systems at Select Water Solutions' site in Howard County, Texas.
  
  
  
  
• The systems are being integrated with Select's existing produced water pretreatment and recycling infrastructure and are expected to begin producing technical-grade and battery-grade lithium carbonate in early Q2 2026.
  
  
  
  
• This initial deployment is intended to support continued bulk sample production and customer qualification while establishing the systems-integration template for planned scaling at the site and future deployments across major U.S. basins, including the Permian and Bakken.

LibertyStream Infrastructure Partners Inc. (TSXV:LIB, OTCQB:VLTLF, FSE: I2D)) ("LibertyStream" or the "Company") announces that it has completed site preparations and begun installation of its direct lithium extraction and lithium carbonate refining systems at Select Water Solutions' (NYSE:WTTR) ("Select") facility in Howard County, north of Midland. The systems are being integrated with Select's existing produced water pretreatment and recycling infrastructure and remain on schedule to commence initial lithium carbonate production early in the second quarter of 2026.

LibertyStream integrating infrastructure at Select's water treatment facility.

This initial deployment is intended to validate LibertyStream's on-site systems integration at Select, support continued bulk sample production for customer qualification and establish the operating template for scaling throughout the remainder of 2026. By integrating its proprietary direct lithium extraction ("DLE") technology and refining systems into existing oilfield infrastructure, LibertyStream continues to advance a repeatable development model for future deployments across high-volume U.S. basins, including the Permian and Bakken.

"Our team has made significant progress over the past month preparing the site and installing our DLE extraction and refining systems at Select's facility," said Alex Wylie, President & CEO of LibertyStream. "We remain ahead of schedule for commissioning and expect to begin initial lithium carbonate production early in the second quarter. This deployment is designed to support bulk sample production and customer qualification while establishing the integration template for planned scaling through the balance of 2026."

LibertyStream Near-Term Strategy

LibertyStream's near-term focus is to complete integration with Select's existing produced water infrastructure and commence lithium carbonate production at the site in early Q2 2026, while advancing the separate commercial-scale expansion targeted to bring annualized production capability to up to 1,000 tonnes by year-end 2026.

To achieve this, the Company intends to:

1. Complete installation, systems integration, and commissioning of its on-site DLE extraction and refining systems in early Q2 2026.

2. Commence lithium carbonate production and continue to ship bulk samples—accompanied by certificates of analysis (COAs)—for customer testing and qualification in both industrial and battery-grade markets.

3. Continue qualifying customers for offtake through an ongoing sampling program supporting additional industrial and battery-grade customer qualification.

4. Advance construction of LibertyStream's separate commercial-scale DLE extraction and refining system later in 2026, targeting annualized production capability of up to 1,000 tonnes by year-end 2026.

This phased approach is intended to move LibertyStream from initial site integration and production testing at Select to commercial-scale deployment during 2026, while establishing a repeatable operating template for future deployments across major U.S. basins.
