NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN WHOLE OR IN PART, TO US PERSONS (AS DEFINED IN REGULATION S UNDER THE US SECURITIES ACT OF 1933 (AS AMENDED)) OR INTO THE UNITED STATES, AUSTRALIA, JAPAN, NEW ZEALAND OR THE REPUBLIC OF SOUTH AFRICA OR INTO ANY OTHER JURISDICTION WHERE TO DO SO MIGHT CONSTITUTE A VIOLATION OR BREACH OF ANY APPLICABLE LAW.

LONDON, September 30, 2024 - Orosur Mining Inc. ("Orosur" or the "Company") (TSX-V:OMI)(AIM:OMI), announces that it has raised the sum of £835,000 (before expenses) through a placing of 30,035,971 new common shares of no par value ("Placing Shares" or "New Common Shares") at a price of 2.78 pence per Placing Share ("Placing Price"), together with a grant of one unlisted warrant to purchase one additional common share exercisable at US$0.0494 (approximately 3.697p) ("Investor Warrant") for every two Placing Shares subscribed for (together the "Placing"). Completion of the Placing is subject, amongst other things, to admission of the New Common Shares to trading on AIM ("Admission").

The Company held cash of US$500,000 (approximately £370,000) as at 27 September 2024, and the additional funds will be used largely to progress the Company's Anzá exploration project in Colombia. Work at Anzá will include drilling at the Pepas prospect and the engagement of external consultants to examine results from 38,000m of drilling at the APTA prospect to determine if a Mineral Resource Estimate may be developed.

Details of the Placing

The Placing Price represents a discount of approximately 15 per cent. to the closing mid-market price of the common shares on 27 September 2024, being the last trading day prior to the release of this announcement of the Placing.

The Placing Shares will, when issued, represent approximately 14.6 per cent of the existing common shares and will represent approximately 12.7 per cent. of the enlarged share capital of the Company.

The Placing was undertaken by Turner Pope Investments (TPI) Ltd ("Turner Pope" or "TPI"), the Company's Joint Broker.

Placing Agreement, Admission and Total Voting Rights

The Company and Turner Pope have entered into a placing agreement ("Placing Agreement") pursuant to which Turner Pope agreed to use its reasonable endeavours to procure placees pursuant to the Placing. The Placing Agreement contains certain warranties and indemnities given by the Company in favour of Turner Pope. It also contains provisions entitling Turner Pope to terminate the Placing Agreement prior to Admission if, among other things, a breach of any of the warranties occurs.

Completion of the Placing is subject, amongst other things, to the 30,035,971 New Common Shares being admitted to trading on AIM and is also conditional upon the Placing Agreement becoming unconditional in all respects and not being terminated in accordance with its terms. Application will be made for Admission. It is expected that Admission will become effective at 8.00am (GMT) on or around 4 October 2024.

Following the issue of the 30,035,971 New Common Shares, which on Admission will rank pari passu with the existing common shares, the total number of common shares in issue with voting rights in the Company will be 235,620,423.

The above figure of 235,620,423 common shares may therefore be used by shareholders as the denominator for the calculation by which they may 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 Placing is subject to approval of the TSX-V. The Placing Price of 2.78 pence translates to 5.0 Canadian cents at the exchange rate of GBP1=CAD$1.8. No finder's fees have been paid as part of the placing.
