Centenario Gold Corp. (CSE: CTG) has provided an update on its initial drill program at the Los Reyes copper-gold skarn project in Chihuahua, Mexico, reporting copper oxide intercepts and vertical extensions of mineralization below the Jibosa and Tueda zones. The announcement, disseminated via NEWMEDIAWIRE, details the completion of five holes totaling 1,140 meters, with 344 core samples sent to ALS Labs in Chihuahua for analysis. No assays have been received yet, so grade and economic potential remain unknown.
The project is located approximately 170 km south of Chihuahua City along Highway 49, a major artery connecting Chihuahua to Torreon and Monterrey. The El Rey mineral claim, which hosts most of the old mine workings, is just off the highway, about 14 km south of the mid-size town of Jimenez, and is easily accessible via a secondary dirt road. Power and rail are nearby, and the local rancher who owns the land supports the exploration work.
Los Reyes is a highly prospective copper-moly-gold skarn system, possibly a carbonate-replacement deposit, situated along the eastern contact between a granodiorite intrusive and Lower Cretaceous limestones and shales. The deposit lies in a regional northwest-trending mineralized belt that includes important old mines such as Santa Eulalia, Naica, La Ojuela, and San Martin. Although Penoles, a major Mexican mining company, holds the rest of the intrusive contact, the Los Reyes concession is the only part with significant historical workings.
Surface mapping and sampling in May 2026 confirmed copper-molybdenum-zinc mineralization at the Tueda and Jibosa zones, and underground mapping in July 2026 confirmed lateral and vertical extensions below those zones. The current drill program has returned notable observations. Hole RYS26-01, drilled between the Jibosa and Tueda Shaft zones, encountered copper oxides about 75 meters below surface and skarn and hornfels between 125 and 175 meters. The hole was completed to 304 meters on November 10, 2026, after overcoming a stuck drill in a clay-rich contact zone. A cross-section and selected drill core from RYS26-01 are available for review.
Hole RYS26-02, drilled just below the Jibosa Shaft zone, hit copper oxides about 75 meters below Jibosa, with a strong interval from 95.7 to 104.2 meters in oxidized zones with abundant hematite and breccia textures. Hole RYS26-03, testing the extension of old workings below the Tueda zone to the north, intersected more than 120 meters of pyrite-dominant sulphides with chalcopyrite, plus quartz-pyrite-molybdenite veinlets in hornfels. Hole RYS26-04 tested lateral continuity 170 meters south of Jibosa and intersected an iron-magnetite skarn from 171 to 187 meters. Hole RYS26-05, located 200 meters north of Tueda, intersected the contact zone at shallow depths between 47 and 61 meters, with core logging ongoing.
According to the company, the drilling so far points to a large intrusion-related copper-molybdenum system with skarn mineralization along the contact. The location and description of drill holes and a location map of drill holes and sections provide further context. For investors, the pending assay results will be critical to determining whether the observed mineralization translates into economic grades. The presence of copper oxides near surface and sulphide zones at depth suggests potential for a sizable system, but without assays, the economic viability remains speculative.
The project's location near infrastructure and the support of the local landowner could facilitate future development if results are positive. Centenario Gold, listed on the Canadian Securities Exchange, continues to evaluate new opportunities in Mexico and Canada.
