80 Mile, an AIM-quoted exploration company and constituent of the FTSE AIM All Share Index, is in an offer period. On 3 November 2026 it announced an extension of the "put up or shut up" deadline and amended terms for a proposed all-share Merger with Greenland Energy Company. A Rule 2.9 announcement followed on the morning of 4 November, and a run of Takeover Code dealing disclosures has filled its announcement list since.

What was announced

According to the 3 November announcement, the deadline for Greenland Energy to announce a firm offer or walk away was extended by seven days to 5:00 p.m. London time on 10 November 2026. The extension gives Greenland time to complete confirmatory Due Diligence on 80 Mile. Under the revised terms, 80 Mile shareholders would receive Greenland shares rather than cash, at an exchange ratio of approximately 0.0079485 Greenland shares for each 80 Mile share, based on 160,500,000 new 80 Mile shares. The summary of the announcement cited an implied value of about 1.596 pence per 80 Mile share, using Greenland's closing price of US$2.68 and an Exchange Rate of 0.75.

The planned issue of warrants has been removed, which takes out a source of dilution. Greenland also indicated it intends to provide a £3.0 million unsecured convertible Loan note with a 12-month term to support 80 Mile's operations while the parties work towards a firm offer under Rule 2.7 of the Takeover Code. No firm offer has been made, and there is no certainty that one will be.

The Disko-Nuussuaq project

On 2 November 2026 the company issued a project update on its Disko exploration work in Greenland. It said it had completed its 2026 drilling programme, with ten diamond core holes totalling 3,926 metres, and that demobilisation and winterisation were complete, with two drill rigs remaining on site. Core samples are being shipped to the ALS laboratory, with delivery expected in about two weeks and assay results due four to six weeks after receipt. The 2027 budget remains subject to further technical review.

Funding position

The company previously announced US$30.0 million of drilling-related funding under what it calls the USFM Agreement. Completing it depends on Greenland government approvals and an extension of the long-stop date, which originally expired on 8 September 2026. The proposed loan note would be a separate bridge while talks continue.

Sector and index context

Greenland has attracted exploration interest because of its geology and strategic mineral prospects, yet its short field season and remote logistics make drilling costly and weather-dependent. Small explorers often rely on partners or Equity funding, so combinations that provide cash and a larger platform are common. The Takeover Code governs how such approaches unfold: the "put up or shut up" mechanism forces a bidder to commit within a set period, though deadlines can be extended with the target's agreement. Dealing disclosures under Form 8.3 and 8.5 are routine in this situation.

Key risks

The main uncertainty is whether a firm offer emerges and on what terms, since the exchange ratio, valuation and conditions can change before then. Shareholders would hold shares in a different company, so the value they receive would move with Greenland's share price. Exploration results from the 2026 holes are yet to be reported, funding approvals remain outstanding and the company has no producing assets. A failed approach could leave 80 Mile needing to find other finance.

What to watch next

The immediate date is 10 November 2026, the extended deadline. Investors will look for the content of the 4 November Rule 2.9 notice, any Rule 2.7 firm offer, assay results from the Disko samples over the coming weeks and clarity on the USFM funding conditions.
