Acceleware acquires Mannville Stack heavy oil assets

Calgary, Alberta--(Newsfile Corp. - June 8, 2026) - Acceleware Ltd. (TSXV: AXE) ("Acceleware" or the "Company") is pleased to announce it has acquired 35 net sections of heavy oil assets located in the Mannville Stack in Saskatchewan (the "Assets") from a private oil and gas company. The Company paid $100,000 cash and granted a gross overriding royalty on future production. The Assets comprise 35 net sections of land across a multi-zone heavy oil fairway, one horizontal well in the Rex zone producing 15 barrels of working interest heavy oil per day before royalties, another horizontal well requiring a workover, along with associated surface leases and infrastructure.

The acquisition provides a low-cost, scalable entry point into a heavy oil resource base aligned with multi-well RF XL 2.0 development. The transfer of well and facility licenses is conditional upon regulatory approval. "This acquisition provides Acceleware with a highly strategic, low-cost entry into a multi-zone Mannville Stack asset with existing production and significant development upside," said Geoff Clark, Chief Executive Officer of Acceleware.

"The assets combine a producing Rex zone well with a large land position which we believe is well suited for both cold-flow multilateral and RF XL 2.0 development. This establishes a strong foundation for future deployment and production growth." The Assets provide a combination of existing production and undeveloped upside, enabling the Company to pursue a staged development approach. Initial plans include maintaining production from the Rex zone, while evaluating production enhancing opportunities in existing wells.

The Company also intends to advance subsurface and reservoir characterization across the stacked Mannville intervals, while completing necessary regulatory and environmental baseline work. Subsequent phases are expected to include drilling multilateral cold-flow horizontal wells and designing an RF XL 2.0 development plan targeting multiple zones. Based on reservoir characteristics identified to date, Acceleware believes select Mannville Stack intervals represent strong candidates for RF XL 2.0 recovery.

This acquisition represents a key step in Acceleware's strategy to build a portfolio of heavy oil assets suited for RF XL 2.0 deployment while generating near-term production. The Assets provide immediate production exposure through the existing Rex zone wells, along with access to bypassed and undeveloped heavy oil resources. In combination with the Company's two previously announced farm-in projects, this acquisition significantly strengthens Acceleware's inventory within a core heavy oil fairway and establishes a platform for scalable development and future technology deployment.
