Southern Empire and Enduro Metals Finalise SMP’s Earn-In of the Pedro Gold Project, México
Southern Empire Resources Corp. (Southern Empire; TSX -V: SMP; Frankfurt: 5RE; OTC: SMPEF) and Enduro
Metals Corporation (Enduro; TSX-V: ENDR) are pleased to announce that they have agreed to close Southern
Empire’s acquisition of the 1,750-hectare Pedro Gold Project (Pedro) in Durango State, México.
Pursuant to amendments of the original Option Agreement (see news release of July 27, 2021), Southern
Empire will now, subject to TSX Venture Exchange approval, acquire a 100% interest in the Pedro mineral
tenements by becoming the owner of a 100% beneficial interest in Minera BRG, S.A. de C.V. (currently the
Mexican subsidiary of Enduro that owns Pedro) by issuing to Enduro 2,000,000 common shares of Southern
Empire and committing to a future milestone payment of $2,000,000 upon commencement of commercial
production. Enduro retains a 2% net smelter return (NSR) royalty interest from future Pedro production with
no buydown provision.
The Pedro Gold Project is located 80 kilometres (~50 miles) from Torreon, México, in the northeastern part of
the state of Durango and approximately 30 km west of the town of Mapimí. At Pedro, a gold exploration target
is outlined at surface by a gold-in-soil geochemical anomaly (greater than 10 parts per billion) with dimensions
of 4,000 metres (m) by 1,000 m. Outcrop exposure comprises prominent hematite -stained, silica-rich ridges
of angular chalcedony fragments and silicified sedimentary rocks within a coarse breccia. Historical sampling
of these exposed zones has returned gold values (in rock) ranging from background levels to a maximum of
2.3 grams gold per tonne (g Au/t) with 58 samples greater than 0.25 g Au/t and 11 greater than 1 g Au/t).
Induced Polarization ground geophysical surveys have defined zones of elevated chargeability and identified
discreet deep target features. Southern Empire completed 856.3 m of core drilling at Pedro in 2022, returning
a best interval of 15.23 m grading 0.577 g Au/t in hole P22-03, approximately 800 m from 2014 drilling by a
subsidiary of Newmont Mining Corporation . Gold mineralization at Pedro is 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. This regional structural setting, together
with a highly anomalous trace element association with arsenic (orpiment and realgar are common),
antimony, mercury and thallium, and alteration indicate a possible “Carlin-style” mineral system.
Quality Assurance/Quality Control (QA/QC) Data Verification Statement
Historical samples mentioned in this release were prepared and analyzed at various times by ALS Chemex at
its labs in Chihuahua, México, and Vancouver, Canada. See news dated September 16, 2012, and July 2, 2014
(historical drill results) posted on SEDAR under Bearing Lithium Corp., and news dated February 19th, 2020 ,
March 30th, 2021 and July 27, 2021 for Commander Resources Ltd. for QA/QC details. Drill samples collected
by Southern Empire were prepared at an ALS Geochemistry lab facility in Chihuahua, Chihuahua State, México
and then shipped by ALS to its North Vancouver, British Columbia facility for gold and multielement analysis
(see Commander and Southern Empire release dated April 27, 2022 for QA/QC details).

About Southern Empire Resources Corp.
Southern Empire is focused on the acquisition, exploration and development of metals and minerals deposits
in North America.
On Southern Empire’s Pedro Gold Project i n northeastern Durango State, México, gold mineralization is
present in 12 of the 17 holes drilled to date. Please see Southern Empire’s news releases posted on SEDAR+ or
www.smp.gold 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).

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

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 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.
