HIGHLIGHTS

Operational and financial highlights for the six months ended November 30, 2024 are set out below:

Operational

·      In Colombia, on November 27, 2024, the Company completed the acquisition of Minera Monte Aguila S.A.S. ("Monte Aguila") as a result of which the Company now has 100% ownership of the Company's flagship Anzá Gold Project. Under the terms of the acquisition, Orosur's wholly owned Canadian subsidiary, Waymar Resources Ltd., purchased all of the issued shares of Monte Aguila from wholly owned subsidiaries of Newmont and Agnico resulting in Orosur regaining 100% ownership of the Project. No cash is payable up front, with all consideration deferred and wholly contingent upon commercial production from the Anza Project. The agreed consideration is a net smelter royalty of 1.5% on all future mineral production, plus a capped fixed royalty of an aggregate amount of US$75 per ounce of gold or gold equivalent ounce on the first 200,000 gold equivalent ounces of mineral production. Completion of the acquisition was subject to customary conditions including the approval of the TSXV, which conditions have all been met. The Company also re-took operatorship of the Anza Gold Project, commencing a drilling program at the Pepas prospect in late November 2024 which has extended post quarter end with very good results.

·      In Argentina, the Company has completed and submitted all the necessary environmental studies that are required as part of the Santa Cruz Province drilling permit process.  Consideration of these reports and drilling approval was expected to take several months. The Company has now received the approval necessary for drilling. A further geo-physical campaign is planned to refine targets after which the Company will consider drilling, likely to take place later in 2025 subject to funding.

·      In Nigeria, the Company will look to make some advances on its lithium project, but at a slower pace whilst lithium prices continue to recover.

·      In Uruguay, the Company's wholly owned subsidiary, Loryser, continues to focus its activities on the final stages of the Creditors Agreement. In line with the Creditors Agreement, Loryser has sold all of its assets. It has paid for the settlements with all of its former employees; it has finalised the reclamation and remediation works on the tailings dam and has successfully concluded a one-year post-closure control phase. Loryser is well advanced in distributing the proceeds to Loryser's trade creditors in accordance with the Creditors' Agreement, via a Court approved settlement agent.

Financial

·      The unaudited condensed interim consolidated financial statements have been prepared on a going concern basis under the historical cost method except for certain financial assets and liabilities which are accounted for as Assets and Liabilities held for sale (at the lower of book value or fair value) and Profit and Loss from discontinuing operations. This accounting treatment has been applied to the activities in Uruguay and Chile.

·      On September 30^th, 2024, the Company announced that it had raised the sum of £835,000 (before expenses) through a placing of 30,035,971 new common shares of no par value at a price of 2.78 pence per Placing Share, together with a grant of one unlisted warrant to purchase one additional common share exercisable at US$0.0494 (approximately 3.697p) for every two Placing Shares subscribed for. 

·      On November 30, 2024, the Company had a cash balance of $945,000 (May 31, 2024 $2,104,000). As at the date of this announcement the Company has a cash balance of $2,200,000.
