Southern Empire to acquire 100% interest in Suaqui

2023-08-28 12:38 ET - News Release

Mr. Dale Wallster reports

SOUTHERN EMPIRE PURSUES THE SUAQUI VERDE COPPER DEPOSIT IN NORTHWESTERN MEXICO

Southern Empire Resources Corp. has entered into an agreement with Cuprum Mining Corp., an arm's-length private Canadian company, that grants Southern Empire the opportunity to acquire up to a 100-per-cent interest in the share capital of Cuprum, and thereby a 100-per-cent beneficial interest in Cuprum's Suaqui Verde copper project that comprises certain mineral tenements located in the mining-friendly state of Sonora in northwestern Mexico.

Suaqui Verde copper project and agreement highlights:

  • The Suaqui Verde copper deposit comprises oxide copper and secondarily enriched copper sulphide mineralization that outcrops at surface and is outlined by approximately 106 historical reverse circulation (RC) and core drill holes.
  • The Suaqui Verde copper deposit is within the world-class Sonora-Arizona porphyry copper province.
  • Cuprum's mineral concessions cover approximately 1,952 hectares (approximately 4,823 acres) of Suaqui Grande municipality in the mining-friendly state of Sonora in northwestern Mexico.
  • The Suaqui Verde copper deposit has been the subject of a series of unpublished, historical open-pit mineral resource estimates, the most recent prepared by Independent Mining Consultants Inc. (IMC) of Tucson, Ariz.
  • The agreement provides for water usage rights and unfettered access to the ranch land surface rights that cover the immediate area of the Suaqui Verde copper deposit.
  • There is good access to the project area, approximately 140 kilometres (87 miles) southeast of the city of Hermosillo (metropolitan population of approximately 850,000) and 116 kilometres (approximately 72 miles) from the port city of Guaymas.
  • Local infrastructure and work force are available in the nearby town of Suaqui Grande (eight km; five miles).
  • Potential development scenarios may include lower-cost open-pit mining and bulk heap leaching, or alternatively, in situ leaching; both possibilities potentially leading to cathode copper production through solvent extraction-electrowinning (SX/EW) processing methods.

Dale Wallster, chief executive officer of Southern Empire, stated: "With Suaqui Verde, I believe that our team can create significant near-term value for Southern Empire shareholders. Copper, which has just been added to the U.S. Department of Energy's list of critical materials, is now often referred to as the new green metal as the electrification and decarbonization of the world will not happen without it. Suaqui Verde presents an exciting opportunity for Southern Empire to enter the green metals arena by acquiring a little-known copper oxide deposit in mining-friendly Sonora. Southern Empire will be able to immediately capitalize on the substantial investments of previous operators as we investigate the significant exploration potential to expand the Suaqui Verde copper deposit at depth. The case for future development is very compelling, especially with the possible implementation of either conventional heap leach processing or innovative in situ leaching processing."

Geology and copper mineralization of the Suaqui Verde area

The Suaqui Verde copper project area covers an outcropping, oxidized porphyry copper deposit located in the world-class Sonora-Arizona porphyry copper province (also known as the Laramide or the Southwestern North America porphyry copper province) where more than 20 porphyry copper-molybdenum deposits have been mined for decades.

Porphyry copper provinces are time-space clusters of porphyry copper deposits. The Sonora-Arizona porphyry copper province comprises adjacent parts of the American states of Arizona, New Mexico and Texas, and the Mexican states of Sonora, Chihuahua, northern Sinaloa and Baja California. This province contains the world's second-largest copper endowment; an estimated total (production plus reserves plus resources) of 295 million tonnes, 96 per cent of which is in deposits of Laramide age (approximately 80 million to 45 million years (Ma)). The province was particularly fertile between 69 Ma and 54 Ma, bracketing the Suaqui Verde deposit mineralization, which is dated at 57 Ma plus or minus 300,000 years.

The Suaqui Verde copper deposit area has been explored by minor underground development and about 150 historical, mostly vertical RC and core drill holes completed by companies including: American Smelting and Refining Company (ASARCO in the 1940s; now part of Grupo Mexico SAB de CV); Industrias Penoles SAB de CV (in 1964); Minera Constelacion SA de CV (Cominco Ltd. in 1971 to 1972; now Teck Resources Ltd.); Duval Corp.; Azco Mining Inc. (AZCO in 1991); Cambior Inc. (Cambior in 1992 to 1994; now Iamgold Corp.); Phelps Dodge Corp. (Phelps Dodge in 1996; now Freeport-McMoRan Inc.); and Minera Corum SA de CV (Minera Corum in 2006 to 2007; now Cuprum). Overburden is generally shallow and the first 50 metres of the copper mineralized zone often returns poor drill recoveries. Copper mineralized zones are known to continue laterally beyond the drill-defined limits of the deposit and only a few Phelps Dodge drill holes started to explore the copper potential at depth.

The geology of the Suaqui Verde project area is similar to other calc-alkaline porphyry-style copper deposits of the region, featuring a multiphase intermediate (silicic) Laramide-age intrusive complex intruding Cretaceous andesitic rocks of the Tarahaumara formation.

Supergene oxidation, leaching and enrichment have modified the character and position of Suaqui Verde copper mineralization, creating an irregular zone of copper oxides, which may reach depths of up to 350 metres. Supergene copper mineralization consists of a mix of chrysocolla ((Cu, Al)2H2Si2O5(OH)4-nH2O), chalcocite (Cu2S), brochantite (Cu4SO4(OH)6), and minor malachite (Cu2CO3(OH)2) and libethenite (Cu2PO4OH). Chrysocolla and chalcocite are regarded as the most desired mineral species for potential extraction of copper by leach processes. Limonitic copper minerals include cupro-hematite and other metallic gangue minerals include hematite, goethite, jarosite and the manganese oxide neotocite.

Hypogene mineralization comprises pyrite (FeS2), chalcopyrite (CuFeS2) and molybdenite (MoS2). Gypsum is common along fractures especially near sulphide-bearing areas.

Historical metallurgical test work indicates that Suaqui Verde copper mineralization should be amenable to either conventional open-pit mining and heap leach copper extraction, or alternatively, in situ leaching. If either of these operational methods were to be implemented, they would produce a copper-enriched solution from which high-purity cathode copper could subsequently be produced by SX-EW (solvent extraction-electrowinning) processing.

In 2008, an independent, historical open-pit mineral resource estimate was prepared as an internal report for Cuprum by IMC of Tucson, Ariz. IMC's unpublished, historical open-pit mineral resource estimate, at selected cut-off grades and based on 106 total drill holes completed between 1991 and 2007, is set out herein.

Geological mapping and structural interpretation, drilling and satellite alteration mapping (ASTER) suggest the Suaqui Verde copper porphyry system has been structurally tilted to the northeast, supporting the potential for deeper sulphide zones extending at depths below historical drilling.

Location, access and infrastructure

Suaqui Verde is in the municipality of Suaqui Grande approximately 140 km southeast of the city of Hermosillo, the capital city of Sonora, Mexico (metropolitan area population of approximately 880,000). The deepwater port city of Guaymas is approximately 116 km from the project.

Suaqui Grande is a town located eight km (five miles) west of Suaqui Verde that was founded in 1620 by the Spanish missionary Martin Burgencio. Access to Suaqui Grande is by national paved highway from Hermosillo. The Suaqui Verde mineral tenements are accessible throughout by a network of unimproved roads. Given the arid local climate and minimal annual rainfall, these gravel roads remain in good condition year-round.

Suaqui Grande can provide all basic infrastructure required for project assessment, including electricity, water, housing, office and secure core storage facilities, and Internet communications.
