Mexoro Minerals Intersects 13 Meters 6.52 G/T Gold and 266.5 G/T Silver and Continues to Extend the Mineralized Body at Its Cieneguita Project In Mexico

CHIHUAHUA, Mexico, Sept. 4 /PRNewswire-FirstCall/ -- Mexoro Minerals Ltd. intersects 13 meters of 6.52 g/t gold and 266.5 g/t silver and continues to extend the mineralized body at its Cieneguita project which remains open to the west. (MXOM.OB) (Frankfurt: OYA1).

Mexoro Minerals Ltd. (BULLETIN BOARD: MXOM) is pleased to announce the results of 6 diamond core drill holes completed in the Central and West part of the Cieneguita project in the state of Chihuahua, Mexico. To date, 52 drill holes have been completed. Assay results are now complete through holes CI-39.

Drilling Results Summary:

-- Drill hole CI-34 further confirmed and expanded near-surface mineralization in the west portion of the known mineralized system at Cieneguita. This hole intersected broad intervals, including: 46.00 meters (0 to 46.0 m) averaging 4.68 g/t Au, 87.67 g/t Ag, 0.24% Pb and 0.22% Zn and 93.0 meters (128.5 to 221.5 m) with 0.10 g/t Au, 15.81 g/t Ag, 0.55% Pb and 0.85% Zn. Hole CI-34 extended the mineralization, originally identified in CI-21, CI-30 and CI-35, further west and it suggests that it remains open in that direction.

-- Drill holes CI-36 and CI-39 intersected significant precious metal mineralization near the surface. Both holes were collared to the north- northeast of CI-34 in the vicinity of Pit No.2, just at the limit of the known mineralized area. CI-36 intersected 33.0 meters (14.50 to 47.5 m) averaging 0.48 g/t Au and 43.89 g/t Ag and 13.5 meters (68.50 to 82.0 m) with 0.53 g/t Au and 41.64 g/t Ag. CI-39 intersected 79.60 meters (12.9 to 91.20 m) averaging 0.43 g/t Au and 17.05 g/t Ag.

-- Three drill holes, CI-26, CI-37 and CI-38, were completed in a low- grade precious and base metal mineralization zone close to an andesitic post- mineral dyke in the central portion of the Cieneguita mineralized system. Drill holes CI-37 and CI-38 intersected important precious metal mineralization starting from surface and ended significant base metal mineralization. CI-38 intersected 91 meters (0 to 91 m) averaging 0.46 g/t Au and 15.20 g/t Ag and ended with 29.05 meters (147.25 to 176.30) averaging 0.26 g/t Au, 31.38 g/t Ag, 0.51% Pb and 1.01% Zn. Hole CI-37 intersected 15 meters (10.50 to 25.5 m) 0.34 g/t Au and 48.88 Ag and ended with 10.60 meters (202.50 to 213.10) with 0.18 g/t Au, 26.89 g/t Ag, 0.54% Pb and 0.69% Zn.

The Cieneguita mineralized deposit is associated with a diatreme breccia body where oxide and sulfide mineralization is mainly hosted by moderately to pervasively quartz-sericite altered diatreme breccias and lapilli tuffs. The mineralized body is shaped like a funnel which has been flattened laterally.

Drill hole CI-34 was collared in the western portion of the Cieneguita mineralized system, where the best grades and greatest thickness of precious and base metals mineralization have been found, which seems to represent the main conduit of the diatreme. Mineralization intersected in CI-34 and CI-29 (previously released) suggests that mineralization still remains open to west, southwest and to depth in the western part of the Cieneguita deposit.

Mexoro's exploration drilling program continues to the west, where access road and drilling platforms have been completed to explore the Cieneguita's potential in the westerly direction. Parallel to this exploration drilling in the western portion, an infill drilling program has been initiated, including preparing access roads and drilling platforms and bringing in a second drill rig. This infill drilling program is designed to significantly expand the inferred mineralization of 14.86 million tons @ 2.12 g/t gold equivalent and to be ready to prepare a more rigorous NI43-101 compliant resource estimation.
