Mexoro Minerals Announces Drill Results From the Cieneguita Project

CHIHUAHUA, Mexico, June 23 /PRNewswire-FirstCall/ -- Mexoro Minerals Ltd. (BULLETIN BOARD: MXOM) is pleased to announce the drill results from three additional holes from the Cieneguita project, located in Chihuahua, Mexico. Drill holes CI-21 to CI-24 were part of the recently completed drill project at Cieneguita, consisting of 31 core holes totaling 7,166 meters. The Company has also included the complete assay results for hole CI-21 (partially reported results from CI-21 in a press release dated May 21, 2008 included 74 meters of 1.72 g/t gold and 119.77 g/t silver).

Partial results from Hole CI-22 stopped in mineralization, including a 5 meter mineralized interval of 1.17 g/t Au and 157 g/t Ag (intercepted at the end of the hole). In addition, the complete assay results from CI-21 included 111.50 meters of 1.24 g/t Au, 99.59 g/t Ag, 0.45% Pb and 0.73% Zn, and 74 meters of 1.72 g/t Au and 119.77 g/t Ag. Hole CI-24 yielded 59.50 meters of 1.31 g/t Au and 60.38 g/t Ag. Hole CI-23 did not encounter economic mineralization.

The Summary of these assay results are seen in the table below (visit http://www.mexoro.com/ for further assay details, and a map showing the locations of holes CI-01 to CI-31).

In a press release dated May 21, 2008, Hole CI-21 was collared to the south of Pit 2 in a southeast direction. This drill hole was designed to test anomalous and high grade gold values obtained from surface samples taken during the mapping process carried out in 2007. The results indicate an expansion of both the near surface oxide mineralization and the deeper sulfide gold-silver (+lead-zinc) mineralization. Gold, silver and base metals mineralization intersected in drillhole CI-21 may represent a new hydrothermal mineralization center at the southwest portion of the Cieneguita system that could significantly increase the potential of the project. Assay results from CI-26 to CI-31 are still pending from ALS Chemex.

Barry Quiroz, VP Exploration for Mexoro, comments, "We are very pleased to see these extensions of the mineralization, and the consistency in grades provides evidence of large bulk tonnage precious metals (+/- base metals) deposit."
