Project Update at Rudyard Project
Helix Exploration PLC has secured a drilling rig for a re-entry and coring program at its Rudyard Project, commencing the week of November 17, 2025, to evaluate potential hydrogen resources by coring ultramafic rock. Previous geochemical studies confirmed a ³He/⁴He ratio of 0.74 Rₐ, indicating a significant mantle helium component. Following coring, the company will perforate the Souris River zone for helium production, aiming to supply its new processing plant and advance its goal of unlocking both helium and hydrogen from the same system.

[{"type":"text","content":"\n\n13 November 2025\nHelix Exploration PLC\n(\"Helix Exploration\" or \"Helix\" or the \"Company\")\nProject Update at Rudyard Project - Rig Secured for Rudyard Re-Entry and Coring Program\nHelix Exploration PLC, the helium exploration and development company with near-term production assets within the 'Montana Helium Fairway', is pleased to announce that it has secured a drilling rig to re-enter the Inez #1 well at its flagship Rudyard Project.\nThe operation represents the next step in evaluating the Rudyard subsurface system for potential hydrogen resources, supported by previous findings of mantle helium signatures and rock chemistry conducive to natural hydrogen generation.\nHighlights\n· Rig Secured for Re-Entry: Helix has finalised a rig contract to re-enter the Inez #1 commencing the week of 17 November 2025.\n· Targeting Hydrogen Source Rocks: The Company will remove existing production tubing and drill through to total depth, coring an additional 30-40 feet of ultramafic rock - the critical rock type responsible for natural hydrogen generation.\n· Evidence of Deep Mantle Connection: As announced on 16 October 2025, geochemical studies have confirmed a ³He/⁴He ratio of 0.74 Rₐ, representing a ~9 % mantle helium component and one of the highest ratios recorded in the continental United States outside Yellowstone.\n· Hydrogen Potential: The combination of altered ultramafic lithologies, mantle helium, and active fluid pathways makes Rudyard one of the most scientifically compelling and economically attractive natural hydrogen prospects in North America.\n· Helium Production Integration: Following coring operations, Helix will perforate the entire Souris River zone to complete the well for helium production, enabling helium bearing gas to supply the Company's new PSA/Membrane processing plant in Rudyard.\nBackground\nNatural hydrogen is the cleanest and most cost-effective hydrogen on Earth, generated deep underground by simple natural reactions between water and ultramafic rock - with zero carbon emissions. Unlike synthetic hydrogen (\"grey hydrogen\") produced from fossil fuels, geological hydrogen offers a self-recharging, emission-free resource.\nHelix intends to deliver near-term helium revenue while pioneering one of North Americ...
