Block Listing Application

London, 08 January, 2025, Orosur Mining Inc. ("Orosur" or "the Company") (AIM/TSXV: OMI), a minerals explorer and developer with projects in Colombia, Argentina and Nigeria, announces that, a block listing application ("Block Listing") has been made to the London Stock Exchange for up to 31,848,219 common shares of no par value each in the Company ("New Common Shares") to be admitted trading on AIM.

Forming part of the Company's successful capital raisings in February, September and December 2024, the Company has in issue a total of 31,848,219  unlisted investor and broker warrants yet to be exercised. Further details are set out below:

The Block Listing has been filed to enable holders of the Company's warrants to continue to voluntarily exercise them without the need for the issue of a separate RNS and admissions filing each time this occurs. The Company will notify on a monthly basis when there are changes to the issued share capital of the Company, and these monthly figures may be used by shareholders as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company. The Company will also make six-monthly announcements regarding the utilisation of the block admission in line with its obligations under AIM Rule 29. It is expected that the Block Listing will be effective on or around 13 January 2025.

If and when issued, the New Common Shares will rank pari passu in all respects with the existing common shares of the Company.
