Bo Sears, CEO of Helix Exploration, commented: "We are delighted with the progress Helix has made over the past six months as we enter the final phase before becoming the first producer of its kind in the State of Montana. The pace at which the team has executed this phase of the Rudyard project is a real testament to their professionalism and commitment. Achieving this level of progress so soon after listing is an exceptional accomplishment. We are excited about the opportunities that production presents for the Company and remain focused on maintaining this momentum through the remainder of 2025, into 2026, and beyond."

Project Update

Progress at the Company's flagship project in the Rudyard field, Montana, continues to advance with multiple workstreams for production nearing completion.

Construction of the Company's main asset, the PSA plant, has now been completed. The plant was assembled by Wikota Design & Construction LLC ("Wikota") at their plant in Houston. A Helix representative has inspected and approved the PSA plant for transport, and it is now being prepared for shipment by truck to the Rudyard site.

On site in Montana, the PSA plant will be housed in our fully completed, custom-built plant facility. Instillation of the membrane and PSA will be conducted by a team of engineers from Wikota, with support from Nu Wave Services of Havre, Montana who have overseen the assembly of key components, including the gathering system, membranes, and electrical and gas supply.

Once the helium compressor unit, which is scheduled for delivery in November 2025, arrives at the site, the final connection process will begin. This is expected to be a two-week process to install and then bring the plant online.

Commercialisation

The Board has a clear strategy to deliver long term value for Helix shareholders as it enters this pivotal stage for the Company. The Board are in discussions with multiple industrial gas companies regarding potential offtake contracts. The Company will update the market accordingly once a contract has been signed with the selected partner.
