CASPER, WY / ACCESS Newswire / December 1, 2025 / Lost Soldier Oil and Gas II Master Series LLC ("Lost Soldier" or the "Company"), a Wyoming Limited Liability Company, today announced it has entered into a Strategic Partnership and Framework Agreement with Upland Resources Limited ("Upland"), (LSE:UPL), a United Kingdom public company, establishing a commercial bilateral investment, intended farm-in arrangements, and a broader operational partnership.

The framework agreement is a combined total of ~USD $8.6 million of bilateral strategic investment through a mutual stock and private placement unit subscription. Lost Soldier will provide technical services support in the areas of drilling, midstream, unconventional development and operational oversight. Lost Soldier has the option to farm-in and participate for up to 20% working interest at the project level in Upland's focus areas in Southeast Asia. Upland gains a strong partner with technical expertise and unconventional high pressure gas experience to develop their projects.

The execution of this framework agreement and bilateral investment represents a significant milestone for Lost Soldier, giving the company exposure to future international oil and gas production. The investment also makes Lost Soldier one of the largest shareholders in Upland, whose primary focus is on exploration and developing oil and gas assets.

This transformative investment provides Lost Soldier with direct exposure to areas of unexplored potential, directly offsetting proven world-class production. The petroleum systems in these areas are well documented and include untapped unconventional targets. This enables Lost Soldier's operational expertise and drilling capability to provide synergy to Upland and value for Lost Soldier's investors and Upland's shareholders.

Marc Bruner, CEO of Lost Soldier LLC, commented: "We are excited by the scale, revenue potential, and long-term prospects of Upland's Southeast Asian opportunities and the exclusive position Upland have secured. This partnership synergizes our experience in large-scale unconventional gas development alongside Upland's high-quality targets. We look forward to advancing these projects and generating sustainable, long-term value for both companies and their shareholders."

Bolhassan Di, Chairman and CEO of Upland, added: "This strategic partnership with Lost Soldier is a significant milestone for Upland. Lost Soldier has a proven track record with the drilling and development of high-pressure gas discoveries. These capabilities align perfectly with the growing requirement throughout Southeast Asia to develop high pressure gas fields and unconventional resources. What began as an introduction through Josh Galloway, now our Head of Drilling Services, over one year ago, has developed into a bilateral investment providing exposure to world-class unconventional gas resources, long-term revenue streams, and substantial operational capability. This agreement positions Upland to accelerate project development, optimize operations, and deliver decades of recurring cash flow and shareholder value."

Upland and Lost Soldier have agreed to a balanced bilateral investment structure, totaling ~ $USD 8.6 million:
