Southern Empire Acquires the La Loma Property in Durango, México and Expands the Centauro Property in Chihuahua, México

VANCOUVER, BC / ACCESSWIRE / December 19, 2022 / Southern Empire Resources Corp. (Southern Empire; TSX-V:SMP; Frankfurt:5RE; OTC:SMPEF) announces the acquisition of the 23,750 hectare ("ha"; 58,687 acre) La Loma gold property by staking. La Loma is located in Durango State, México approximately 50 kilometres ("km") southeast of Southern Empire's Pedro Gold Project and 35 km west-southwest of the major city of Torreón (see Figure 1).

Southern Empire also announces the expansion of its recently optioned Centauro Gold ("Au") Project (see Southern Empire news release dated December 12, 2022) located near Jiménez, Chihuahua from an original 600 ha to 4,432 ha (10,951 acres) with the staking of the Tauros and Centauro 2 claims.

"Southern Empire's La Loma, Pedro and Centauro gold projects support our theory that a northwest trending metallogenic belt of "Carlin-style" and/or low sulphidation epithermal gold deposits extends through northern central México. Our projects all exhibit many of the geological and mineralogical features that define these important precious metal deposit types," stated David Tupper, Southern Empire's VP of Exploration.

La Loma Property

Southern Empire's La Loma, Pedro, and Centauro Gold Projects occur within the north Mexican Oligocene Basin and Range physiographic province. These three project areas define a 150-kilometre trend of gold occurrences that are associated with arsenic-mercury-antimony mineralization, together with silica and clay alteration, all hosted in the same package of Cretaceous limestones and mudstones and Tertiary ignimbrite eruptive and polymictic conglomerate lithologies.

As part of the "Laramide" Lower Cretaceous to early Tertiary, Mexican Fold and Trust Belt, the stratigraphy of the area exhibits repeated, elongate north-south folds that are regularly interrupted by moderate- to high-angle thrusts and later extensional faulting (see Figure 2).

A significant portion of the La Loma property covers "Terrano Naccional" (federal land) and is therefore unencumbered by private or communal Ejido ownership (see Figure 2). Access is limited to several broad, ephemeral riverbeds (arroyos) extending from the south.

The La Loma property covers a large, unexplored area having Au, arsenic ("As"), antimony ("Sb"), mercury ("Hg"), molybdenum ("Mo"), and silver ("Ag") stream sediment geochemical anomalies as reported by the Secretaria de Economia de México, ("SGM") in 2006 (see Figure 3). This government stream sediment sampling survey was completed at a low, regional density. Additionally, much of the regional geological mapping was accomplished with the aid of stereoscopic interpretation.

Hyperspectral mapping (ASTER 2003/06; see Figure 2) shows that these geochemical anomalies are often coincident with zones of strong silica alteration.

The SGM regional geochemical sediment sample results also suggest significant potential for Carbonate Replacement Deposit ("CRD") mineralization in the La Loma area, especially with the Ojuela and La Platosa CRD mines (both now closed) located only 50 km to the north. Significant anomalies supporting the prospectivity for CRD mineralization also occur to the southeast of the La Loma claim, however this is a protected area.

At La Loma, Southern Empire has planned exploration programs for spring 2023 that will include:

• Higher density stream sediment sampling
• Prospecting and preliminary geological mapping

Centauro Property Expanded by Staking

The Centauro property has been significantly expanded by staking two claims totalling 3,832 ha that surround the 600-ha claim block, which is held under option by Southern Empire. This staking extends the project area up to 7 kilometres to the west (see Figure 4).

The Tauros and Centauro 2 claims cover areas of silica and kaolinite alteration, and lesser alunite and buddingtonite alteration, as recently identified and mapped (by analysis of Worldview-3 hyperspectral data) along trend and to both the northwest and the northeast of the original Centauro claim block. These suites of probable alteration mineralization are often spatially associated with "Carlin-style" and/or low sulphidation epithermal gold mineralization observed at Centauro to date.

Southern Empire has initiated negotiations to secure surface access rights at the Centauro Gold Project with the local rancher owners who have worked with the claim owner for more than 30 years.

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 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).

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.

Cautionary Notice Regarding Exploration Work Programs

The timing and the ability to conduct Southern Empire's exploration programs are, among other things, contingent on: governmental regulations allowing for the issuance of permits; affects of the COVID-19 pandemic; and the availability of property access, exploration personnel, drill contractors, equipment, lodging, etc. 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.
