Southern Empire’s Centauro Gold Project Option Transferred to Fortuna Mining

Southern Empire Resources Corp. (Southern Empire; TSX -V: SMP; Frankfurt: 5RE; OTC: SMPEF) announces

that, regarding the Centauro Gold Project located in Chihuahua, México, it has entered into agreements (the

Assignment Agreements) that will allow Monumental Minerals, S.A. de C.V. (“Monumental”), a subsidiary of

Fortuna Mining Corp. (Fortuna; NYSE: FSM; TSX: FVI), to replace Southern Empire as the Optionee of record

in an Option Agreement with the original property vendor (see Southern Empire news release of December

12, 2022), thereby permitting Fortuna , through Monumental, the ability to earn a 100% interest in three

Centauro Gold Project mineral claims totaling 600 hectares (~1,483 acres).

Pertinent Business Terms of the Centauro Gold Project Option Assignment Agreements

Pursuant to the Assignment Agreements, and in exchange for Fortuna replacing Southern Empire as Optionee,

Fortuna may pay to Southern Empire a total of US $975,000 as follows:

• US $ 25,000 (plus VAT) upon the execution of the Assignment Agreements (the “Execution Date”)

• US $ 25,000 (plus VAT) on the first anniversary of the Execution Date

• US $ 25,000 (plus VAT) on the second anniversary of the Execution Date

• US $ 25,000 (plus VAT) on the third anniversary of the Execution Date

• US $ 25,000 (plus VAT) on the fourth anniversary of the Execution Date

• US $350,000 (plus VAT) on the fifth anniversary of the Execution Date

• US $500,000 (plus VAT) upon the filing of a Preliminary Economic Assessment technical report

regarding the Centauro Gold Project

Should the Centauro Gold Project attain commercial production, Southern Empire will retain a 1% Net Smelter

Return royalty interest with Fortuna having the right to a 0.5% buyback for US $1 million anytime prior to

commercial production.

Fortuna, through Monumental, has committed to spend a minimum of $200,000 annually in exploration ,

following an initial 12-month period to allow for drill permitting and the completion of initial reconnaissance

exploration work.

Inclusive in the transaction’s terms, Southern Empire has agreed to issue 400,000 common shares to the

original property vendor. Additionally, should Fortuna at any time decide to drop the Option, then Southern

Empire will have the ability to re-establish itself as Option ee of the Centauro Gold Project with the right to

earn a 100% interest by assuming all remaining payment and other relevant commitments to the underlying

owner that Fortuna might have at that particular time.

The transactions contemplated herein are subject to acceptance of the TSX Venture Exchange.

Centauro Gold Project

The Centauro property is in southeast Chihuahua State, approximately 275 kilometres (171 miles) southeast

of Chihuahua City. The extensive silica alteration exhibited at Centauro, coupled with an array of positive

geochemical, geophysical and historical drill results (see Southern Empire news release of December 12,

2022), point to the strong potential of the property to host a significant epithermal and/or “Carlin -style”

precious metal mineral deposit. Geological features exhibited at Centauro closely reflect those observed at

Southern Empire’s Pedro Gold Project located near Mapimí, in Durango State.

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, México, 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 dep osited 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 t o 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).

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

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 unce rtainties 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

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 the 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 grad es 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.

Cautionary Notice Regarding Proposed Exploration Work Programs

The timing and the ability to conduct Southern Empire's planned or proposed exploration programs are, among

other things, contingent on: governmental regulations allowing for the issuance of permits; affects of the

COVID-19 pandemic; the availability of exploration personnel, drill contractors, equipment, lodging, etc; and

the availability of capital required for exploration programs . Southern Empire will adhere to COVID -19

directives regarding safe working practices putting worker and community health and safety first and will

proceed with exploration and development work programs only if potential COVID-19 risks can be effectively

managed.

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.
