Southern Empire Announces Private Placement Financing

Southern Empire Resources Corp. (Southern Empire; TSX-V: SMP; Frankfurt: 5RE; OTC: SMPEF) announces the close of its previously announced non-brokered private placement financing (see news release dated June 16, 2025) of 2,000,000 units (a "Unit") at a price of $0.05 per Unit for gross proceeds of $100,000 (the "Offering").

Each Unit consists of one common share of Southern Empire (a "Share") and one share purchase warrant of Southern Empire (a "Warrant"). Each Warrant entitles the holder to purchase one additional Share at a price of $0.10 per Share for a period of three years from the date of issue.

No finders' fees were paid under the Offering. The securities issued under the Offering will be subject to resale restrictions for a period of four months and 1 day from the date of issue.

The funds of the Offering will be used for administrative costs associated with Southern Empire's mineral properties in Mexico as well as working capital purposes

About Southern Empire Resources Corp.

Southern Empire is focused on the acquisition, exploration and development of metals and minerals deposits in North America.

In northeastern Durango State, Mexico, Southern Empire has an option to acquire a 100-per-cent beneficial interest in the 1,750-hectare Pedro Gold Project. At Pedro, in the spring of 2022, Southern Empire drilled gold mineralization approximately 800 metres from 2014 drilling by a subsidiary of Newmont Mining Corporation. Gold mineralization, associated with highly anomalous arsenic (orpiment and realgar common), antimony, mercury and thallium, has been identified hosted in permeable basal conglomerates deposited during Oligocene extensional deformation, the latter forming widespread Basin and Range physiography along the easter part of Sierra Madre Occidental. Gold is present in 12 of the 17 holes drilled at Pedro to date. Please see Southern Empire's news releases posted on SEDAR+ for further details.

In the Cargo Muchacho mountains of Imperial County, California, Southern Empire owns 100 percent of the historical gold-producing American Girl mine property and holds options to acquire a 100 percent interest in the adjacent 2,160-hectare (5,338-acre) Oro Cruz Property located approximately 22.5 kilometres (14 miles) southeast of the operating Mesquite gold mine of Equinox Gold Corp.

At Oro Cruz, extensive historical drilling and large-scale open-pit and underground mining of the American Girl, Padre y Madre, Queen, and Cross oxide gold deposits by the American Girl Mining Joint Venture ("AGMJV") occurred between 1987 and 1996. During that time, gold was recovered by either heap leaching of lower- grade, or milling of higher-grade ores until AGMJV operations ceased in late 1996 because of declining gold prices leaving the Oro Cruz Property with many gold exploration targets in addition to a historical inferred resource estimate, reported In 2011 by Lincoln Mining Corp., totaling 341,800 ounces gold based on 4,386,000 tonnes averaging 2.2 grams gold per tonne (g Au /t) at a cut-off grade of 0.68 g Au/t (4,835,000 tons at 0.07 ounce gold per ton; please refer to the Cautionary Notice Regarding the Oro Cruz Property Historical Resource Estimate below).

On behalf of the Board of Directors of Southern Empire Resources Corp., Dale Wallster, CEO and Director

Cautionary Notice on Forward-Looking Information

Information provided in this news release may contain forward-looking information or forward-looking statements that are based on assumptions as of the date of this news release. Such information or statements reflect management's current estimates, beliefs, intentions, and expectations and are not guarantees of future performance. Southern Empire cautions that all forward-looking statements are inherently uncertain and that actual performance may be affected by many material factors, many of which are beyond its respective control. Such factors include, among other things: risks and uncertainties relating to Southern Empire's limited operating history, the need to comply with environmental and governmental regulations, results of exploration programs on its projects, and those risks and uncertainties identified in its annual and interim financial statements and management discussion and analysis. Accordingly, actual and future events, conditions, and results may differ materially from the estimates, beliefs, intentions, and expectations expressed or implied in the forward-looking information. Except as required under applicable securities legislation, Southern Empire undertakes no obligation to publicly update or revise forward-looking information.

Cautionary Notice Regarding Historical Resource Estimate

The Oro Cruz Project historical resource estimate is disclosed in a technical report dated April 29, 2011, prepared for Lincoln Mining Corp. by Tetra Tech, Inc. and filed on Canadian Securities Administrators' System for Electronic Document Analysis and Retrieval ("SEDAR"). It is termed an inferred mineral resource, which is a category set out in NI 43-101. It was based on historical reverse circulation and core drill hole sample, underground channel sample, and blasthole sample assay results and calculated using ordinary kriging to estimate gold grades in 10-foot-by-10-foot-by-five-foot blocks. Accordingly, Southern Empire considers this historical estimate reliable as well as relevant as it represents key targets for future exploration work. However, a QP has not done sufficient work to verify or classify the historical estimate as a current mineral resource and Southern Empire is not treating this historical estimate as current mineral resources.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the Exchange) accept responsibility for the adequacy or accuracy of this release.
