Centenario Gold Reports Copper Oxide Intercepts and Extends Vertical Mineralization Below Jibosa & Tueda Zone on the Los Reyes Copper-Gold Skarn Project in Chihuahua State, Mexico NewMediaWire Thu, November 12, 2026 at 6:00 AM EST 9 min read CTG.CN -4.17% HG=F -1.36% GC=F -1.18% VANCOUVER, B.C - November 12, 2026 (NEWMEDIAWIRE) - Centenario Gold Corp. (CSE: CTG) ("Centenario" or the "Company") is pleased to announce an update on the initial drill program on the Company's Los Reyes Project (the "Project") in Chihuahua, Mexico. To date, there have been 5 holes completed for a total of 1140 meters with a total of 344 core samples taken. All samples are being sent to ALS Labs in Chihuahua, Mexico.
The Los Reyes Project is located approximately 170 km south of Chihuahua City, along Highway 49, a main artery connecting the city of Chihuahua to the major cities of Torreon and Monterrey further south. The project's El Rey mineral claim, where most of the old mine workings are located, sits just off Highway 49, some 14 km south of the mid-size town of Jimenez and can be easily accessed driving up a secondary dirt road for a few kilometers. The project has power and rail nearby and the landowner, a local rancher, supports the exploration work.
Los Reyes is a highly prospective copper-moly-gold skarn system, possibly a carbonate-replacement deposit (CRD), that lies along the eastern contact between a granodiorite intrusive (about 1.5 2 km) and Lower Cretaceous limestones and shales. The deposit sits in a regional northwest-trending mineralized belt that hosts important old mines such as Santa Eulalia, Naica, La Ojuela and San Martn. 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.
Centenario Gold Exploration Program Highlights
Surface mapping and sampling in May 2026 confirmed Cu-Mo-Zn mineralization at the Tueda and Jibosa zones.
Underground mapping and sampling in July 2026 confirmed the lateral and vertical extensions of Cu-Mo-Zn mineralization below the Tueda and Jibosa zones. (See News Release on July 13th 2026)

RYS26-01 hit copper oxides about 75 m below surface, & skarn y hornfels between 125 -175 m.
RYS26-02 hit copper oxides about 75 m below Jibosa.
RYS26-03 intersected more than 120 m of pyrite-dominant sulphides with chalcopyrite, plus quartz-pyrite-molybdenite veinlets in hornfels.
RYS26-04 hit an iron-magnetite skarn (171–187 m).
RYS26-05 is testing a northeast-trending extension of the Tueda zone.
Hole RYS26-01 was drilled in the middle between the Jibosa and Tueda Shaft zones. The drill hole location was designed to evaluate the mineralization intrusive-sediment contact zone at 120 meters depth and also to test a deeper, very strong geophysical IP anomaly (greater than 25 ms) that IMMSA obtained from their geophysical work completed in the late 1950s.
At about 105 meters of depth (see Photo below), the drill got stuck in the clay-rich granodiorite-sediment contact zone so drilling was put on hold. The problem was resolved and drilling of RYS26-01 resumed and was completed at a depth of 304 meters on the 10th of November 2026.

The zone of contact in Hole RYS26-01 was intersected between at 78.5 m. The rocks at the contact gradually change from granodiorite to diorite dike, to skarn, and finally to dolomitic limestones, The granodiorite and diorite dike rock contains quartz-pyrite veinlets, with abundant sericite. The skarn portion of the intersection, between 98.5 m to 103.7 m, contains strongly oxidized quartz-calcite veinlets, with the sporadic Cu oxides.

Examples of different alteration styles observed in RYS26-02: Marble, Limestone, Hornfels
Hole RYS26-02 was drilled just below the Jibosa Shaft zone. The hole reached the granodiorite-limestone contact zone at 75 m, testing the continuity of the Cu-oxide mineralization at the Jibosa zone. One of the best intervals was encountered between 95.7 m and 104.2 m in strongly Cu oxidized zones with abundant hematite, breccia textures with quartz veinlets. Another quartz-oxide zone was intersected between 109.40 m and 111.0 m. At depth, a sequence of hornfels was intersected containing sporadic quartz veinlets, piryte, and traces of chalcopyrite y molybdenite.

Drill hole RYS26-03 tested the extension of the old mine workings below the Tueda zone to the North. About 100m down, strated to enter the contact zone which contained more sulfides, mainly pyrite, than Jibosa to the South. Zones of breccia textures were intersected at intervals 123.0–126.0 m and 129.30-143.0 m show evidence of Cu minerals. At depth, between 228.0 and 239.2 m, the hole intersected a zone intercalated hornfels and skarn with pyrite veintes containing traces of calchopirita y molibdenite.
Drill hole RYS26-03 intersected granodiorite, including intervals of very fine-grained intrusive material. Alteration is characterized by varying degrees of strong potassic alteration. Particularly noteworthy are the sulfides and breccias intervals between 129.3 m and 144.4 m, 151.5 m -163.7 m, 168.2 m - 176.7 m, and 185.1 m - 204.7 m, intervals containing abundant pyrite with trace chalcopyrite. Another mineralized interval occurs from 168 m to 204 m, while quartz-pyrite-molybdenite veinlets were observed within hornfels between 229 m and 239 m.

Hole RYS26.04 tested the lateral continuity of mineralization 170 meters south of the Jibosa zone, The granodiorite-dolomitic limestones contact zone was prominent between 171.0 m a 190.6 m, where a pyrite-magnetite skarn with traces of calchopyrite was intersected at deeper depths the rock alteration changes to chlorite -sericite dominant with fluorite veinlets.

Drill hole RYS26-05 is located 200m north of the Tueda zone. As expected, the hole intersected the contact zone at shallow depths, between 47.0m to 61.0. Core logging on this hole is still ongoing.
No assays have been received at this time and will be released once received. A total of 344 samples have been taken from holes 1 – 5 and have been shipped to ALS Lab in Chihuahua, Mexico. The drilling so far points to a large intrusion-related Cu-Mo system, with skarn mineralization along the contact. Grade and economic potential won't be known until the drilling assays come back.
