("ECR Minerals", "ECR" or the "Company")

Result of significantly oversubscribed WRAP Retail Offer

ECR Minerals plc (AIM: ECR), the gold exploration and development company focused on Australia, is pleased to confirm that, further to the announcements made on 1 October 2025, that it has raised aggregate gross proceeds of £100,000 pursuant to the WRAP Retail Offer, alongside the previously announced Subscription. Accordingly, the Company will issue a total of 50,000,000 new Ordinary Shares at the Issue Price pursuant to the WRAP Retail Offer. The WRAP Retail Offer was significantly oversubscribed.

In total, the Subscription and the WRAP Retail Offer have conditionally raised gross proceeds of £750,000 for the Company, via the Subscription of 325,000,000 Subscription Shares and 50,000,000 WRAP Retail Offer Shares.

Admission and Total Voting Rights

Application has been made for the Subscription Shares and the WRAP Retail Offer Shares to be admitted to trading on AIM ("Admission"). Admission is expected to become effective on or around 8 October 2025.

Upon Admission, the Company's issued ordinary share capital will consist of 2,644,512,954 Ordinary Shares with one voting right each. The Company does not hold any Ordinary Shares in treasury. Therefore, from Admission the total number of Ordinary Shares and voting rights in the Company will be 2,644,512,954. With effect from Admission, this figure may be used by Shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

The new Ordinary Shares to be issued pursuant to the WRAP Retail Offer will be issued free of all liens, charges and encumbrances and will, on Admission, rank pari passu in all respects with the new Ordinary Shares to be issued pursuant to the Subscription and the Company's existing Ordinary Shares.

Terms used but not defined in this announcement have the same meaning as those set out in the Company's announcement released at 13:00 on 1 October 2025.
