Operational Overview

The Sagebrush Project continues to deliver steady oil production from multiple wells, providing an important revenue stream alongside the Company's helium development activities.

During 2025, the project produced 11,769 barrels of oil gross, and generated sales revenue of US$617,044 gross, with Quantum's net sales revenue after royalties but before lease operating costs of approximately US$409,000. Production was delivered consistently throughout the year with regular sales, supporting Quantum's strategy of leveraging hydrocarbon revenues to help fund and de-risk its helium exploration and appraisal programmes.

Production has continued into 2026 in line with expectations, with January and February delivering stable output from the Sagebrush wells. The Company intends to provide a further update on production for the quarter ending 31 March 2026 at the Company's annual financial year end.

The Company continues to optimise hydrocarbon/oil production across the Sagebrush field while progressing towards the extended production test at the Sagebrush-1 well, which remains the primary near-term operational focus.

The recently completed 3D seismic survey at Sagebrush has significantly improved subsurface understanding and identified additional structural features prospective for hydrocarbons. These targets represent potential future drilling opportunities which could support further growth in oil production over time, complementing the Company's helium-focused development strategy.

Strategic Importance of Oil Production

Oil production at Sagebrush plays a dual role within Quantum's broader strategy:

·      Provides near-term revenue generation

·      Supports funding of helium-focused operations and development

·      Demonstrates existing production capability within the asset base

This integrated approach allows Quantum to advance its helium portfolio while maintaining financial discipline and operational momentum. This revenue contribution, combined with strengthened oil prices, further enhances the financial resilience of the Company as it progresses towards helium production.

Market Context

The Company notes the recent strengthening in global oil prices amid ongoing geopolitical developments in the Middle East. Whilst commodity prices are subject to volatility, the current pricing environment is supportive of increased revenues from the Company's existing oil production which remains unhedged.

Outlook

Quantum expects oil production at Sagebrush to continue alongside its helium-focused activities, with the Company now positioned to enter a highly active period with the planned extended production test at Sagebrush-1.

Howard McLaughlin, Chief Executive Officer of Quantum Helium, commented: "Our 2025 oil production from Sagebrush highlights an important and often underappreciated part of the Quantum story. While our primary focus is on unlocking the significant helium potential across our portfolio, the existing oil production provides us with a valuable source of revenue that helps to support our ongoing operations and helps fund our development activities.

Production has continued in line with expectations into 2026, and with oil prices strengthening in response to global geopolitical developments, this part of the business becomes increasingly valuable. It reinforces our strategy of combining helium exploration with hydrocarbon production to create a more resilient and self-sustaining business model as we move towards the extended production test at Sagebrush-1 and the next phase of growth."
