Centenario Gold Corp. Provides Update on Initial Drill Program at Los Reyes Project

November 12, 2026, Vancouver, B.C. — Leads & Copy — Centenario Gold Corp. (CSE: CTG) has provided an update on its initial drill program at the Los Reyes Project in Chihuahua, Mexico. To date, five holes have been completed, totaling 1140 meters, with 344 core samples collected and sent to ALS Labs in Chihuahua for analysis.

The Los Reyes Project is situated approximately 170 km south of Chihuahua City, accessible via Highway 49. The El Rey mineral claim, which hosts most of the historical mine workings, is located about 14 km south of Jimenez, with easy access from the highway via a secondary dirt road. The project benefits from nearby power and rail infrastructure, and the landowner has expressed support for the exploration efforts.

Geologically, Los Reyes is described as a prospective copper-moly-gold skarn system, potentially a carbonate-replacement deposit (CRD). It is positioned along the eastern contact of a granodiorite intrusive and Lower Cretaceous limestones and shales. The deposit lies within a northwest-trending mineralized belt that includes significant historical mines such as Santa Eulalia, Naica, La Ojuela, and San Martín. While Peñoles, a major Mexican mining company, controls the remainder of the intrusive contact, the Los Reyes concession is unique for its substantial historical workings.

Centenario Gold's exploration program included surface mapping and sampling in May 2026, which confirmed Cu-Mo-Zn mineralization at the Tueda and Jibosa zones. Further underground mapping and sampling in July 2026 confirmed the lateral and vertical extensions of this mineralization below these zones.

The initial five drill holes have provided preliminary geological observations. RYS26-01, drilled between the Jibosa and Tueda Shaft zones, encountered copper oxides around 75 meters below the surface, followed by skarn and hornfels between 125-175 meters. It reached the granodiorite-limestone contact zone at 78.5 meters. Drilling of RYS26-01 was completed at a depth of 304 meters after an interruption due to difficult ground conditions.

RYS26-02, drilled below the Jibosa Shaft zone, tested the continuity of Cu-oxide mineralization at the Jibosa zone, reaching the granodiorite-limestone contact zone at 75 meters. Notable intervals included strongly Cu oxidized zones with abundant hematite and breccia textures between 95.7 m and 104.2 m. Deeper intervals contained hornfels with sporadic quartz veinlets, pyrite, and traces of chalcopyrite and molybdenite.

Drill hole RYS26-03, which tested the extension of old mine workings north of the Tueda zone, encountered more sulfides, primarily pyrite, starting around 100 meters down. Breccia textures with Cu minerals were observed at intervals, and deeper sections showed intercalated hornfels and skarn with pyrite veinlets containing traces of chalcopyrite and molybdenite.

RYS26-04, located 170 meters south of the Jibosa zone, tested lateral mineralization continuity. It intersected a pyrite-magnetite skarn with traces of chalcopyrite between 171.0 m and 190.6 m, with alteration changing to chlorite-sericite dominant with fluorite veinlets at deeper depths.

Drill hole RYS26-05, situated 200 meters north of the Tueda zone, intersected the contact zone at shallow depths between 47.0 m and 61.0 m. Core logging for this hole is ongoing.

The company has stated that no assay results have been received yet and will be released upon receipt. The drilling to date suggests a significant intrusion-related Cu-Mo system with skarn mineralization along the contact, though the grade and economic potential remain to be determined by the upcoming assay results.

Derrick Strickland, an independent Qualified Person as defined by National Instrument 43-101, has reviewed and approved the technical disclosures in this release. The company noted that mineralization on adjacent properties is not necessarily indicative of mineralization on the Los Reyes Project.
