3 November 2025

Binding Heads of Term Reached With US Group to Joint Venture Disko-Nuussuaq Project, Greenland

80 Mile PLC ('80M' or the 'Company'), the AIM, FSE, and OTC.BLLYF listed exploration and development company with projects in Greenland, Finland and Italy, is pleased to announce that it has entered into a Binding Head of Terms ("HoT") with USFM Corporation ("the US Partner") setting out the terms for the US Partner to fund US$30 million to earn 51 percent of the Disko-Nuussuaq project in West Greenland ("Disko") (the "Proposed Transaction"). 80 Mile will act as the operator and will receive a management fee equal to 12.5% of the total expenditure as well as a £500,000 cash payment upon signing of definitive agreements.

Under the HoT, the US Partner will fund an initial US$30 million to earn a 51 percent legal and beneficial interest in Disko. 80 Mile will be free carried for its 49% until completion of the earn in then will contribute or dilute.

The HoT explicitly state that all funds are to be directed towards drilling rather than reprocessing data with a minimum of US$10 million to be spent on drilling related activities within 10 months of the signing of the HoT.

USFM Corporation is based in Golden, Colorado, home to the Colorado School of Mines from which the the Company intends to work with current professors & recent post graduates and will also select two interns for the upcoming drilling programme in spring / summer of 2026.

Roderick McIllree is expected to join the board of USFM Corporation following the Proposed Transaction, subject to agreements and approvals. 80 Mile currently owns 100 percent of Nikkeli Greenland A/S, the holder of the Disko licenses.

Roderick McIllree, Executive Director of 80 Mile, commented:

"The global race for critical resources shows no sign of slowing. Greenland sits at the center of this story, and we sit at the center of Greenland's resource landscape. As custodians of several of the country's most significant commodity projects, we are entering an exciting new chapter. Jameson and Disko stand among the most exceptional assets in Greenland, with scale and potential that carry far-reaching implications for global supply security.

"It has taken time and determination to reach this point, but with recent progress at Hydrogen Valley and growing interest from the U.S. administration in Greenland's critical minerals, our timing could not be better. This joint venture represents another major milestone for both Disko and 80 Mile. The funding structure has been purpose built to accelerate drilling and resource definition while preserving our operational leadership through the project's most decisive early stages.

"Disko is rapidly emerging as one of the world's most prospective copper, nickel, cobalt and PGE districts. Surrounded by Anglo American at the licence boundary, this agreement gives us the capital to finally answer the question: "What is this thing?"

"We look forward to working closely with our U.S. partners and, pending final approvals, delivering the first systematic drilling ever undertaken at Disko. This partnership is a clear endorsement of the quality of the project and of our broader strategy to unlock Greenland's immense mineral potential. There is much more to come."

Transaction Overview

•      The US Partner will fund US$30 million of expenditure on the Disko licences to earn a 51 percent legal and beneficial interest in Disko.

About the Disko-Nuussuaq Project

Located on the south-west coast of Greenland, Disko has shown its potential to host mineralisation similar to the nickel/copper sulphide mine Norilsk-Talnakh located in northern Russia. Seven significant Magmatic Massive Sulphide ("MMS") targets have been identified to-date at the licence area, with the largest being confirmed now at 5.9 kilometres ("km") long by 1.1km wide. A 28 tonne ("t") boulder of pure massive sulphides assayed 6.9% nickel, 3.7% copper, 0.6% cobalt and 2 grammes per tonne platinum group metals has also been discovered on the licence area. This boulder is on display at the Danish Geological Museum in Copenhagen. A 28t boulder of metal rich massive sulphides clearly demonstrates the significant potential of the project.

A surface sampling programme undertaken by the company confirmed the existence of a working sulphide system (Photo 1) at Disko, initial results returned averaged between 4.6%-9.3% nickel & 1.5-2.8% copper. (Photo 2)

Fresh samples taken from outcrops confirmed characteristics indicative of large-scale Ni-Cu-Co-PGE sulphide segregation and coarse grained inter-locking crystals of metal sulphides were observed in hand specimens with an average crystal size of +15cm indicating that the significant accumulation / precipitation times required for formation of large-scale MMS deposits has occurred. (Photo 3)

Magmatic massive sulphide deposits are extremely rare and extremely valuable. Notably, based on combined reserves, resources, and historical production, it has been estimated by independent parties that the total value of ores in the Norilsk-Talnakh district surpassed US$1.4 trillion based on 2020 metal prices (Barnes et al., 2020). Disko is estimated to have 28% more picritic lavas than Norilsk. Picritic lavas are magmas sourced from the mantle, a metal dense layer inside the earth and a critical prerequisite for large scale metal accumulations in surficial magmatic massive sulphide deposits.

The Disko and Nuussuaq Project comprises six MELs covering a total area of 3,015 square kilometres located on Disko Island and the Nuussuaq Peninsula in Central West Greenland. The project area is located approximately 120 kilometres northwest of Ilulissat, Greenland's third-largest city, which serves as the educational, commercial, and administrative hub of Central West Greenland, with a population of 4,700. Ilulissat is well-equipped with essential infrastructure including an airport, deep-water port facilities, and various service providers. Notably, a new international airport is currently under construction and is anticipated to be operational by the end of 2025. Since 2016, 80M has maintained a logistical base in Ilulissat, facilities designed to support its operations at Disko-Nuussuaq projects. Additionally, the Nikkeli operates a modular exploration camp for up to 40 personnel situated at the abandoned coal mining town of Qullissat on Disko Island. The Disko-Nuussuaq Project is hosted within the West Greenland Flood Basalt Province ('WGFBP'). The WGFBP is associated with the initial phase of continental breakup and the onset of seafloor spreading of the Labrador Sea during the early Paleogene. This province serves as a recognized geological analogue to the Siberian Flood Basalts of the Noril'sk Region of Siberia. This analogy was first recognised by Cominco (now Teck) and provided the exploration framework that has guided subsequent exploration efforts.
