Completion of Jameson Environmental Surveys

80 Mile PLC ("80 Mile" or the "Company"), the AIM, FSE, and OTC listed exploration and development company, is pleased to acknowledge the announcement from Greenland Energy Company, 80 Mile’s joint venture partner for the Jameson Land Basin Project in East Greenland (“Jameson”), regarding the completion of the environmental baseline surveys at Jameson.

On 19 August 2026, Greenland’s Ministry of Business and Mineral Resources granted White Flame Energy A/S, the license holder and 80 Mile’s 100%-owned subsidiary, approval for field activities under OEEL 2015/13 and OEEL 2015/14, covering the period through to 30 September 2026. The approved programme comprised soil and freshwater sampling, vegetation and habitat studies, and the documentation of wildlife and bird activity throughout the project area, with a particular focus on the proposed well locations and the coastal landing site.

These additional baseline surveys built on the extensive environmental studies already completed by the Company at Jameson and provide additional data to support the ongoing Environmental Impact Assessment (EIA) and permitting process.

About 80 Mile PLC

80 Mile PLC is listed on London’s AIM market under the ticker 80M, the Frankfurt Stock Exchange under the symbol S5WA, and traded on the U.S. OTC Market under the ticker BLLYF. 80M is an exploration and development company focused on Hydrocarbons and High-Grade Critical Metal projects in Greenland and an industrial gas and biofuels business in Italy. 80 Mile offers both portfolio and commodity diversification focused on hydrocarbons, base and precious metals, while expanding into sustainable fuels and clean energy solutions in Tier 1 jurisdictions. 80 Mile's strategy is centred on advancing key projects while creating value through partnerships and strategic acquisitions.

80 Mile’s Jameson Project covers 8,429km² across three licences in East Greenland and represents one of the world’s largest remaining untapped gas and liquids-rich basins. An independent 2025 assessment by Sproule ERCE estimated the basin contains 13.03 billion barrels (P10) of recoverable oil, with 80 Mile’s retained interest equating to 3.9 billion barrels valued at approximately US$92 million (based on the listing price of GLND). More than US$275 million has been invested historically by major energy companies and government institutions. In 2025, a milestone agreement with March GL (to be renamed Greenland Energy Co, NASDAQ: GLND) enabled plans for two fully funded 3,500-metre drill holes in the second half of 2026, after which GLND will earn a 70% interest in the Jameson Project, leaving 80 Mile with 30%.

The Disko-Nuussuaq Project, located in West Greenland, covering a district-scale 3,020km² area. Disko is recognised as a world-class geological setting for copper, nickel, cobalt and PGEs, with potential for a Tier-1 nickel-copper discovery analogous to Siberia’s Norilsk Nickel District. The project features multiple walk-up drill targets and which includes seven large, high-priority geophysical anomalies. In late 2025, the company entered into a JV agreement with USFM Corporation under which USFM will fund US$30 million in drilling-related expenditure, including US$10 million in spring/summer 2026, to accelerate drilling and resource definition at Disko. The funding structure will allow 80 Mile to retain operational leadership during the project’s critical early stages.

The Dundas Project, located on Greenland’s northwest coast, is recognised by independent bodies as the world’s highest-grade ilmenite project and the second-largest titanium occurrence globally after Russia. The area hosts high-purity ilmenite, the primary mineral for titanium. Dundas has a JORC-compliant Mineral Resource of 117 million tonnes at 6.1% ilmenite, with further upside highlighted by a late-2024 maiden exploration target of up to 540 million tonnes of additional ilmenite-bearing material. A recent survey by Geological Survey of Denmark and Greenland further impresses on the prospectivity of the area with an estimate of up to 17 billion tonnes (non-JORC) of pure ilmenite within the broader province. With a completed bankable feasibility study and all exploitation permits in place, the project is positioned as a major near-term revenue opportunity for 80 Mile as the company seeks development partners.
