Helix Exploration starts drilling at Inez-1

Helix Exploration PLC has commenced drilling the Inez-1 well at its Rudyard Project in northern Montana, targeting the Souris River and Red River formations within the southern dome, which holds 2C gross contingent resources of 280.00 million cubic feet of helium. This fourth production well is crucial for potentially expanding the company's helium reserves, with drilling expected to conclude within 10-14 days. Concurrently, Helix is advancing towards operational readiness with on-site plant pad construction beginning this month and full plant mobilization anticipated by late July 2025, underscoring its transition to production.

Analysis

Helix Exploration PLC (AIM:HEX) has initiated a key operational phase by commencing the drilling of its Inez-1 well at the Rudyard Project in Montana. This well is strategically significant as it is the first to target the project's southern dome, which holds an estimated 280 million cubic feet of 2C gross contingent helium resources. While it is the fourth well in the field, a successful test of the Souris River and Red River formations in this new area could materially expand the company's reserves, representing a critical de-risking event. The operational timeline is aggressive, with drilling expected to last 10-14 days, followed immediately by wireline logging and flow tests, providing a near-term stream of potential catalysts. Concurrently, the company is making tangible progress in its transition to a producer, with on-site plant pad construction beginning in June and full plant mobilization scheduled before the end of July 2025. This dual focus on resource expansion and infrastructure development, underscored by management's commentary on disciplined execution, signals a clear strategic pivot from exploration to production.

Key Decisions for Investors

• Investors should closely monitor the drilling and subsequent flow test results from the Inez-1 well over the next few weeks, as a positive outcome would validate the southern dome's potential and likely serve as a significant stock catalyst.
• The company's ability to meet its stated timelines for plant construction this month and full mobilization by the end of July is a key indicator of execution risk; any delays could impact the projected start of production.
• Given this is the first well in a new dome, the outcome is binary; a successful test could lead to a substantial re-rating of the asset, while failure would confine proven resources to the previously drilled areas, making this a high-impact, short-term event to watch.
