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
Centenario Gold Corp. has provided an update on the
initial drill program on the
company's
Los
Reyes
project
in Chihuahua, Mexico. To date, there have been five holes completed for a total of 1,140 metres with a total of 344 core samples taken. All samples are being sent to ALS Labs in Chihuahua, Mexico.
Location and access
The
Los
Reyes
project
is
located approximately 170
kilometres south of Chihuahua,
along Highway
49,
a
main artery connecting the
city of
Chihuahua
to
the major
cities
of
Torreon and
Monterrey farther
south. The
project's
El Rey mineral
claim,
where
most
of
the
old
mine
workings
are
located,
sits just
off
Highway
49,
approximately 14
km south
of
the
mid-size
town of
Jimenez, and can be easily accessed by driving
up a
secondary dirt road for a few kilometres. The project has power and rail nearby and the landowner, a local rancher, supports the exploration work.
Geology
Los Reyes is a
highly
prospective copper-molybdenum-gold skarn system, possibly a carbonate-replacement deposit (CRD), that lies along the eastern contact between a granodiorite intrusive (about 1.5 by two 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 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.
Centenario Gold exploration program highlights
Surface mapping and sampling in May, 2026, confirmed copper-molybdenum-zinc 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 dated July 13, 2026).
Current core logging notes:
-
RYS26-01 hit copper oxides about 75 m below surface, skarn and hornfels between 125 and 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 to 187 m).
-
RYS26-05 is testing a northeast-trending extension of the Tueda zone.
Drill hole RYS26-01
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 metres depth and also to test a deeper, very strong geophysical IP (induced polarization) anomaly (greater than 25 milliseconds) that IMMSA obtained from its geophysical work completed in the late 1950s.
At about 105 metres of depth, 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 metres on Nov. 10, 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 and 103.7 m, contains strongly oxidized quartz-calcite veinlets, with the sporadic copper oxides.
Drill hole RYS26-02
Examples of different alteration styles observed in RYS26-02:
marble, limestone and 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 copper-oxide mineralization at the Jibosa zone. One of the best intervals was encountered between 95.7 m and 104.2 m in strongly copper-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, pyrite and traces of chalcopyrite and molybdenite.
Drill hole RYS26-03
Drill hole RYS26-03
tested the extension of the old mine workings below the Tueda zone to the North. About 100 m down, the hole started to enter the contact zone, which contained more sulphides, mainly pyrite, than Jibosa to the south. Zones of breccia textures were intersected at intervals 123.0 to 126.0 m and 129.30 to 143.0 m, showing evidence of copper minerals. At depth, between 228.0 and 239.2 m, the hole intersected a zone intercalated hornfels and skarn with pyrite veinlets containing traces of chalcopyrite and molybdenite.
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 sulphide and breccia intervals between 129.3 m and 144.4 m, between 151.5 m and 163.7 m, between 168.2 m and 176.7 m, and between 185.1 m and 204.7 m; these intervals contain 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.
Drill hole RYS26-04
Hole RYS26-04
tested the lateral continuity of mineralization 170 metres south of the Jibosa zone. The granodiorite-dolomitic limestones contact zone was prominent between 171.0 m and 190.6 m, where a pyrite-magnetite skarn with traces of chalcopyrite was intersected at deeper depths the rock alteration changes to chlorite-sericite dominant with fluorite veinlets.
Drill hole RYS26-05
Drill hole RYS26-05
is located 200 m north of the Tueda zone. As expected, the hole intersected the contact zone at shallow depths, between 47.0 m and 61.0 m. Core logging on this hole is still continuing.
Conclusion
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 to 5 and have been shipped to ALS Labs in Chihuahua, Mexico. The drilling so far points to a large intrusion-related copper-molybdenum system, with skarn mineralization along the contact. Grade and economic potential will not be known until the drilling assays come back.
