Los Reyes sampling confirms copper-moly-gold skarn system

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. a) samples taken at surface from rock outcrops near the central area,   b) 11 samples taken from old waste dumps and shallow pits near the Tueda shaft   c) 42 samples collected underground, 12 at the Tueda mine, and 30 at the Jibosa mine   Click Image To View Full Size Photo A. Location of the two exploration targets at Los Reyes: the Tueda and Jibosa Shaft Zones 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 mete
