# Results From The Surface And Underground Sampling Program Confirm The Existence Of A Significant Copper, Moly, Gold Skarn System At Los Reyes *2026-07-13T06:00:00-04:00* Results From The Surface And Underground Sampling Program Confirm The Existence Of A Significant Copper, Moly, Gold Skarn System At Los Reyes (TheNewswire) |  | | --- | | | July 13th, 2026 – TheNewswire -Vancouver, B.C. - CentenarioGoldCorp.(TSXV:CTG)("Centenario”orthe“Company”)ispleasedto announce thattheCompanyhasreceived the assay results fromthe surface and underground rock samples collected at theLosReyesProject(“the Project”) last month. The Los Reyes Project is ahighlyprospective 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 areencountered.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. 1. 1. 1. a)samples takenat surface from rockoutcropsnearthecentralarea, 2. b)11samples taken fromoldwastedumpsandshallowpitsneartheTuedashaft 3. c)42samples collected underground, 12 attheTuedamine, and 30attheJibosamine[]() [](https://www.thenewswire.com/data/tnw/clients/img/b16515c61e046a470d7890590688e9ca.png) 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 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.

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. | Sample No. | Type | Environment | Location | WIDTH (m) | Cu_% | Mo_% | Zn_% | Au g/t | Ag g/t | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | 417962 | Grab | Old Dumps & Pits | 2 m deep | 1.8 | 0.04 | 1.29 | 0.12 | 0.02 | 4.5 | | 417963 | Grab | Old Dumps & Pits | 3 m deep | 2 | 0.05 | 1.13 | 0.09 | 0.03 | 8 | | 417964 | Grab | Old Dumps & Pits | 5 m deep | 1.2 | 0.32 | 2.19 | 0.06 | 0.08 | 13.6 | | 417997 | Channel | Underground | 25 m down | 1.2 | 0.22 | 0.04 | 1.10 | 0.05 | 2.3 | | 417998 | Channel | Und
