Centenario samples 27.9% Cu, 0.31 g/t Au at Los Reyes

Mr. Doug Fulcher reports

RESULTS FROM THE SURFACE AND UNDERGROUND SAMPLING PROGRAM CONFIRM THE EXISTENCE OF A SIGNIFICANT COPPER, MOLY, GOLD SKARN SYSTEM AT LOS REYES

Centenario Gold Corp. has received the assay results from the surface and underground rock samples collected at the Los Reyes 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 copper-rich skarn zones are encountered. The samples were collected from two major old mining areas located 200 metres apart along the mineralized intrusive-limestone contact: the Tueda shaft zone and the Jibosa shaft zone.

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. Samples taken at surface from rock outcrops near the central area;
  2. 11 samples taken from old waste dumps and shallow pits near the Tueda shaft;
  3. 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 metres in width and 100 meters in length, and can extend for 100s of metres 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 per cent Cu (copper) and 2.88 per cent Zn (zinc), 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 per cent 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 metres below surface.

Tueda shaft zone

The underground rock samples taken at the Tueda mine have returned significant Mo (molybdenum) and anomalous Au (gold) 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 four to six holes, totalling 1,500 metres, is planned to commence in early August.

QA/QC (quality assurance/quality control) 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, less than five centimetres in diameter, taken across rock outcrops with the use of a chisel and hammer. Samples weighted between 1.5 kilograms and 2.0 kg and length of sample cuts varied from 0.6 m to 3.0 m. 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 seven 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 overlimits greater than 1 per cent were further analyzed using the analytical method Cu-OG62, Mo-OG62 and Zn-OG62.
