ASP Isotopes said it completed the wells required for phase 1 of the Renergen helium project about four months ahead of schedule, marking a faster-than-planned buildout at the Virginia gas project in South Africa.
Since operations restarted in April 2025, the company said the project has advanced across drilling, gas production and plant readiness. The phase 1 drilling program has now reached the required cumulative nameplate flow rate, which the company said materially reduces execution risk for the first phase.
A key operational change came from bringing in a U.S.-based specialist in exploration, well design, drilling and reservoir modeling. The company said that shift helped improve target selection and well design, and recent drilling success produced gas flow rates as much as 16 times those achieved in some earlier wells.
ASP Isotopes said the next step is to tie the new wells into the processing plant over the next few months. Once the wells are completed and production-ready, total flow is expected to meet or exceed phase 1’s nameplate capacity. The company said production will then be increased to match customer demand and off-take capacity.
On the project’s longer-term output, ASP Isotopes reiterated that after phase 1 is completed during 2026, it expects Renergen to produce 2,500 gigajoules per day of LNG and 58 thousand cubic feet per day of liquid helium. After phase 2, which it said carries an anticipated 44-month timeline after phase 1, output is expected to rise to 34,000 gigajoules per day of LNG and 895 thousand cubic feet per day of liquid helium.
The company also pointed to a tightening helium market. It said Qatar accounts for more than 25% of global liquid helium production, and cited U.S. Geological Survey data showing Qatar supplied about 2.3 billion standard cubic feet of helium in 2025, or almost a third of global supply. ASP Isotopes said the market has previously seen prices above $1,000 per mcf during supply crises. Today the company's shares have moved 3.48% to a price of $7.74.
