Mexoro Minerals Announces Inferred 15.25 Million Tons Grading 2.62 g/t Gold Equivalent at Its Cieneguita Project in Mexico

January 14, 2009

CHIHUAHUA, Mexico, Jan. 14 /PRNewswire/ — Mexoro Minerals Ltd. Announces
Inferred 15.25 Million Tons Grading 2.62 G/T Gold Equivalent At Its Cieneguita
Project. (OTC Bulleting Board: MXOM) (Frankfurt: OYA1).

Mexoro Minerals Ltd. is pleased to announce that it has updated its
preliminary technical report estimate at its Cieneguita Project located in
Chihuahua, Mexico. The Company finalized its current drilling program
finishing 100 holes for a total of 20,215 meters of drilling. The Company is
waiting for the results from 48 of these drill holes to come back from
analysis by ALS Chemex labs. Once all the results have been received from the
drilling program, the Company plans to complete a rigorous reserve estimate.
In the interim Dana Durgin, a Certified Professional Geologist with Delve
Consultants, has updated its preliminary cross section-based geologic model
and has calculated inferred mineralized material of 15.25 million tons at a
grade of 2.62 g/t gold-equivalent. These figures represent an in-situ
inferred geologic resource with no consideration of metallurgical recoveries
or smelter returns. His technical report discusses potential recovery factors
and individual metal contents in detail, and the report will be posted soon on
http://www.mexoro.com. This preliminary estimate was done to better understand
the geologic controls of mineralization, and the distribution of areas
requiring more drilling, rather than as a rigorous reserve estimate. Mr.
Durgin is independent of Mexoro by the definitions and criteria set forth in
Canadian National Instrument 43-11. The inferred mineralized material
described conforms to the definitions adopted by the CIM on December 11, 2005.

The Cieneguita deposit is hosted in a diatreme breccia, shaped like a
funnel which has been flattened laterally. At the surface the mineralized
body is approximately one kilometer long and averages 200 meters in width.
The north and south sides are nearly vertical; the east and west sides are
more gently inclined. One of the drill holes was stopped in the breccia at
290 meters, thus the breccia body extends to at least that depth. As well,
the mineralized deposit remains open to the south west.

In calculating the estimate, geology and individual assays from 52 drill
holes were displayed on a cross-section based construction of a set of
orthogonal sections, with surface and drillhole geology and assays plotted on
each section, and as such a three dimensional geologic model was compiled. A
cut-off grade of $30 per ton gold-equivalent was applied and weighted averages
calculated to define the boundaries of mineralized bodies. On cross sections,
mineralization was projected half the distance to adjacent sections, and half
the lateral distance to adjacent holes or 50 meters, whichever was less. The
gold-equivalent figures were calculated using a three year trailing average of
$727.77 per ounce gold, $13.66 per ounce silver, $1.00 per pound lead, and
$1.36 per pound zinc.

The best grades and greatest thicknesses of this Au-Ag-Pb-Zn
mineralization are concentrated in the western half of the deposit, south of

Glamis Gold’s earlier Pit #2. Management believes that Pit #2 is also the
area of the inferred throat of the diatreme, so mineralization is expected to
extend to greater depths in that area.

Barry Quiroz, President stated, “This NI 43-101 compliant resource
estimate is a key first step in advancing the Cieneguita gold project towards
the feasibility stage. These results suggest great consistency and continuity
of the project’s mineralization and having taken in consideration only 50% of
the completed drill holes, we see the potential of Cieneguita to emerge as one
of the major discoveries in the region.”

These results have been prepared under the supervision of Barry Quiroz,
MSc., Mexoro’s President. He has the expertise and authority to verify the
authenticity and validity of this data. The qualified person who has done the
geologic modeling and the resource calculation and has reviewed this news
release is Dana C. Durgin, M. Sc. Economic Geology. He is a Certified
Professional Geologist (CPG #10364) with the American Institute of
Professional Geologists, and a Registered Professional Geologist in Wyoming
