CALGARY, AB , April 14, 2026 /PRNewswire/ - Avanti Helium Corp.(TSXV: AVN) (OTC: ARGYF) ("Avanti" or the "Company") is pleased to announce a major execution milestone at its flagship Sweetgrass Helium Project in Montana, having advanced the initial payment installment required to commence final plant modifications, disassembly, and relocation of its helium processing facility to Montana.

This payment formally initiates the next phase of development, allowing plant optimization work, disassembly, logistics coordination, and mobilization activities to begin immediately, marking the transition of Sweetgrass from late-stage development into the final path toward production.

The Company continues to target first helium production by mid-2026, positioning Avanti to become one of the few new North American helium producers entering the market at a time of tightening global supply and growing U.S. strategic demand.

A Major Step Toward Production

The processing plant, which was previously constructed and successfully operated, will now undergo final project-specific modifications before being transported to the Company's Sweetgrass site in Montana for installation and commissioning.

With this milestone now underway, Avanti expects project activities to accelerate significantly over the coming weeks, including:

• Final plant modifications and optimization
• Plant disassembly and transport logistics
• Montana lease site preparation and civil work
• Facility pad construction and infrastructure tie-ins
• Piping, metering, and compression installation
• Final commissioning and start-up preparation

These activities are expected to run in parallel to support the Company's targeted mid-year production timeline.

Montana Site Work to Begin Immediately

In parallel with plant relocation activities, Avanti is preparing to commence site development and lease construction work in Montana, ensuring the Sweetgrass location is ready for plant installation immediately upon arrival.

Ground crews and construction contractors are positioned to begin work as conditions allow, including:

• Site grading and lease preparation
• Civil earthworks and pad construction
• Building and utility installation
• Wellsite integration and inlet infrastructure
• Final pipeline and facility connections

This coordinated execution strategy is designed to compress the timeline to production and materially de-risk the final development phase.

Chris Bakker, CEO of Avanti Helium, commented:

"This is an extremely exciting milestone for Avanti and a major step forward for the Sweetgrass project.

Advancing the initial payment to begin plant modifications, disassembly, and relocation moves us decisively into the execution phase and puts us firmly on the path toward targeted mid-year production. With site work in Montana beginning in parallel, we are now seeing all the major pieces come together to transform Sweetgrass into a producing helium asset and position Avanti for meaningful near-term Helium Production."

Positioned for a Tightening North American Market

As global helium markets remain tight and U.S. supply security becomes increasingly important, Avanti believes Sweetgrass is uniquely positioned to provide a secure North American source of high-purity helium supply.

Upon commissioning, Sweetgrass is expected to become one of the few new domestic helium production facilities entering the U.S. market in the near term, supporting industries including semiconductors, aerospace, healthcare, advanced manufacturing, and defense.
