Mexoro Minerals Intersects 23 Meters 8.93 g/t Gold and 63.39 g/t Silver and Continues to Extend the Mineralized Body at Its Cieneguita Project in Mexico

Mexoro Minerals Ltd. Intersects 23 Meters From Surface Of 8.93 g/t Gold and 63.39 g/t Silver And Continues To Extend The Mineralized Body At Its Cieneguita Project Which Remains Open to the West. (OTC Bulletin Board: MXOM.OB) (Frankfurt: OYA1).
Mexoro Minerals is pleased to announce an additional 8 drill holes (CI-40 to CI-47) which are part of the current drilling programs whose objectives are: (1) to extend known mineralized areas by step-out drilling and (2) infill drilling to expand the newly reported inferred mineralized material (see release dated August 29, 2008) for the project. The drilling program is currently drilling hole CI-58 and assay results are still pending for the last 10 completed drill holes. The most significant results for this series of drill holes were encountered in holes CI-44, CI-46 and CI-47:
– CI-46 intersected 23.00 meters averaging 8.93 grams per ton gold and 63.39 grams per ton silver, including 3.75 meters 32.4 g/t gold and 72.0 g/t silver and 1.5 meters of 34.0 g/t gold and 318.0 g/t silver.
– CI-47 intersected 48.80 meters with 0.86 grams per ton gold, 166.91 grams per ton silver, 0.52% lead and 1.10% zinc.
– CI-44 intersected 18.40 meters averaging 1.10 grams per ton gold and 30.25 grams per ton silver.
As the mineralized material is widely disseminated, all drill results are true width. The detailed results are shown below and the geology, the drill logs and the drill hole locations can be found at http://www.mexoro.com/projects/cieneguita.asp
DRILLING RESULTS:
– Drill holes CI-44, CI-45 and CI-46 have confirmed and expanded mineralization in the west-southwest parts of the Cieneguita mineralized body. The three drill holes intersected broad intervals of mineralization and have ended in mineralization prior to reaching their target depth. Diamond drill hole CI-46, which intersected 23.00 meters averaging 8.93 grams per ton gold and 63.69 grams per ton silver, further demonstrates the continuity and depth extent of mineralization in the main part of the Cieneguita deposit. Drill holes CI-44 and CI-45 have extended mineralization a minimum of 100 meters to the southwest of previously reported drill hole CI-34. Hole CI-44 intersected 18.40 meters averaging 1.10 grams gold per ton and 30.25 grams silver per ton whereas CI-45 intersected 43.00 meters with 0.5 grams gold per ton, 36.51 grams silver per ton, 0.28% lead and 0.40% zinc.
– Hole CI-46 is a significant hole because it has high grades over a long interval (23.00 meters of 8.93 grams per ton gold and 63.39 grams per ton silver) — the first time this has been seen at the Cieneguita project. It included two assay intervals greater than 32 grams per ton. This intercept suggests that there are high grade, structurally controlled zones within the more generally disseminated body of mineralization, which may help to raise the overall grade of the deposit.
With these new mineralized intervals, mineralization at Cieneguita has been traced along a length of 1,000 meters and remains open to west-southwest and to depth in the western part of the mineralized body.

– Drill holes CI-40, CI-41 and CI-47 were completed in the central-east part of the Cieneguita mineralized body and intersected attractive mineralization grading 48.80 meters averaging 0.86 grams per ton gold, 166.91 grams per ton silver, 0.52% lead and 1.10% zinc including 16.70 meters averaging 1.18 grams per ton gold, 366.86 grams per ton silver, 0.76% lead and 1.76% zinc. These intersections extend at least 50 meters to the south the previously reported high-grade intersections in drill hole CI-25.
Drill hole CI-40 was collared in the eastern portion of the Cieneguita system close to the western limit of the Pit 1 area intersecting several intervals including 1.88 grams per ton gold over 4.50 meters.

– Drill holes CI-42 and C-43 were collared to the west of the Cieneguita mineralized body beyond the known limit of the mineralization. CI-42 was completed in the west-northwest edge of the known limit of mineralization intersecting attractive gold intervals and broad intervals of lead, zinc, silver mineralization. CI-42 returned 15 meters averaging 0.42 grams per ton gold and 17.23 gram per ton silver and 22.60 meters grading 40.89 grams per ton silver, 0.71% lead and 1.13% zinc. CI-43 intersected favorable alteration and local mineralization grading 0.46 grams per ton gold over 18.00 meters and 53.84 grams per ton silver over 15.00 meters.

Barry Quiroz, VP Exploration says, “These results demonstrate the continuity and depth extent of main mineralization on that portion of the system. Additional drilling will be required to test the full extent of the mineralization zone to the west-northwest part of the Cieneguita system.”
Reconnaissance-style exploration and a detailed mapping and sampling program of the Piedras Blancas area, 500 meters to the south, are currently in progress, aimed to identify additional drilling targets within Mexoro’s concessions at its Cieneguita project.
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.
