July 13th, 2026 – TheNewswire - Vancouver, B.C. - Centenario Gold Corp. (TSXV: CTG) ( " Centenario ” or the “ Company ” ) is pleased to announce that the Company has received the assay results from the surface and underground rock samples collected at the Los Reyes Project (“the Project”) last month. The Los Reyes Project is a highly prospective copper and gold asset located near the city of Chihuahua, Mexico.

In May, a program of mapping and sampling of the old mine dumps and underground workings over at the El Rey mineral concession was completed. The samples were taken along the intrusive-limestone contact zone where historical Cu-rich skarn zones are encountered. The samples were collected from two major old mining areas located 200 meters apart along the mineralized intrusive-limestone contact: the Tueda shaft zone and the Jibosa shaft zone (see Photo A. & Figure 1.).

Except for three grab samples and five chip samples taken at surface; all samples collected were channel cut samples taken across rock outcrops. A total of 58 samples were taken from either surface, waste dumps and pits, and underground workings.

      2. b) 11 samples taken from old waste dumps and shallow pits near the Tueda shaft  

      3. c) 42 samples collected underground, 12 at the Tueda mine, and 30 at the Jibosa mine

JIBOSA SHAFT ZONE

Most of the underground samples collected at the Jibosa mine were taken from the peripheral margins of the mineralized skarn body that was previously exploited by IMMSA in the mid 1900s. These copper-rich zones have historically been known to reach up to 30 meters in width and 100 meters in length, and can extend for 100s of meters further down and laterally along the intrusive-sediment contact. The 28 underground rock samples taken at Jibosa have returned significant copper and zinc values.

One grab sample at Jibosa, no. 417995, which returned 7.19% Cu and 2.88% Zn, was taken from a stockpile of rock material that appeared to represent the ‘mine feed’ that was taken out of the Jibosa mine at the time. The high-grade 27.9 % Cu value obtained from rock sample no. 417968, came from a 0.6 m wide fracture filling zone that outcrops along one of the tunnel walls 20 meter below surface.

TUEDA SHAFT ZONE

The underground rock samples taken at the Tueda mine have returned significant Mo and anomalous Au values. This suggest that Au is present in the Los Reyes mineralized system and that its occurrence and grade can increase significantly laterally and at depth.

Results from the mapping and rock sampling program completed during the first phase of exploration at Los Reyes have enabled the Company to better understand the mineralized system and also helped in fine tuning the location, orientation and depth of the drill holes. The upcomig core drilling program, consisting of 4 to 6 holes, totalling 1500 meters, is planned to commence in early August.

QA/QC Sample Preparation and Analytical Procedures

The rock sampling program undertaken on the Los Reyes Property was supervised by a senior professional geologist. The rock samples consisted of rock chips, < 5cm in diameter, taken across rock outcrops with the use of a chisel and hammer. Samples weighted between 1.5 kg and 2.0 kg and length of sample cuts varied from 0.6m to 3.0m. Sample chips were collected in a cotton cloth bag, labelled, and tied with a string.

At the end of the day, the samples were transferred to larger corn bags, labelled, sealed with a zip-tie and transported to the town of Jimenez and stored in the senior geologist’s hotel room. Once the 7 days sampling program was completed, the samples were transported by the senior geologist directly to the ALS Chemex Preparation Laboratory in the City of Chihuahua, Chihuahua.

The rock samples delivered to ALS Chemex were geochemically analyzed using the Au-AA23 and ME-ICP61 analytical methods. The Cu, Mo and Zn over-limits greater than 1% were further analyzed using the analytical method Cu-OG62, Mo-OG62 and Zn-OG62.
