EP Empire Metals Corp

Colombian Mines Corporation ("Colombian Mines" or "the Company") (TSX
VENTURE:CMJ) is pleased to announce the discovery of two new gold bearing zones
at Rio Negro and the continued definition of high grade gold mineralization on
the Yarumalito drill project. Work programs are ongoing at the Company's
projects as provided in the update below. For further project information,
please refer to the Company website at www.colombianmines.com.


YARUMALITO

Drilling. Drilling at Yarumalito is ongoing under the expanded drill program as
announced in the Company's press release dated July 30, 2010. The Company is
executing its plans to drill up to an additional 6,800 meters of core at
Yarumalito to evaluate both multiple high grade structurally controlled veins
and the bulk tonnage potential in the La Escuela and Balastreras porphyry
systems. Drill results are expected later this month.


MMI Soil Samples. Field crews are conducting detailed, close-spaced Mobil Metal
Ion (MMI) sampling and have completed roughly 25.8 line kilometers of the MMI
grid. This recent sampling program, designed as a grid on nominal 25 meter
sample spacing along lines that are 100 meters apart, will provide much more
detail than the initial MMI grid which consisted of 100 meter sample spacing on
lines 500 meters apart. Alternate lines are being submitted for initial
analysis, with remaining lines retained for future analysis in areas of
anomalies identified by the initial samples. This program is designed to improve
definition of strong linear anomalies visible on the MMI geochemistry map on the
Company's website that suggest multiple structurally controlled zones of high
grade mineralization. Added detail is expected to also help define zones of
structural intersection, where higher grade gold mineralization is expected to
occur. The initial coarsely spaced sample grid displayed MMI results for gold
that were up to 8,600 times background (Response Ratio) along the Escuela -
Poleala ("EP") structural trend, which is interpreted to be more than 3,000
meters long on strike. The EP trend has also been intersected in recent
drilling, where the Company encountered multiple high grade drill intercepts
including hole YAR-011 grading 33.75 grams per metric tonne gold (g/T Au) over
1.8 meters, and in outcrop channel samples that include the recently reported
2.8 meters grading 18.9 g/T Au. The current MMI sampling will also cover areas
where historic sampling yielded channel sample results averaging 11.5 g/T Au
over 6 meters, with individual samples in excess of 21 grams per tonne gold (g/T
Au) in an area of extensive soil and colluvial cover.


Geophysics (Magnetometry). With the recent completion of approximately 23.5 line
kilometers of high resolution ground magnetometry (mag), the Company now has
33.7 kilometers of mag data over the core of the Property. This high resolution
ground mag was conducted along the same lines as the MMI, and when combined with
those results, the increased definition will assist in targeting future drilling
and exploration for both the high grade vein and porphyry style mineralization.
An updated map of the ground mag is currently available on the Company's
website.


RIO NEGRO

At the Company's Rio Negro project, the ongoing surface rock chip channel
sampling program has discovered two new structural zones with grades and widths
that may be amenable to underground mining. Results include 11.43 g/T Au over a
1.5 meter sample width and 9.59 g/T Au over 1.15 meters from vein structures
with no prior prospecting or mining. Both samples represent an approximate true
width of the structure at the surface. Additionally, multiple narrow, irregular
structures in the same area have returned up to 23.75 g/T Au from veins hosted
in substantially the same intrusive and metamorphic rocks that host the majority
of mineralization in the California and Vetas Districts located roughly 23
kilometers northeast of Rio Negro.


As previously reported, vein structures continue to be found that are associated
with two intersecting structural trends. The primary mineralized trend is
northeast oriented, and is parallel to the major mineralized structures in the
California District. Recognition of the importance of northeast veining and
fault structures is leading Company geologists to examine similarly oriented
linear topographic anomalies on the property that could represent new
exploration targets. A second mineralized fault system trending north-northwest
and paralleling the regionally extensive Bucaramanga Fault Zone is also being
examined, with particular attention paid to areas where these structures
intersect the northeasterly faults and vein zones.


All samples with anomalous gold contained elevated tellurium (Te) with a strong
correlation coefficient of 0.68 (1 being perfect correlation and zero being no
correlation), and with a peak value of 210 ppm Te in a sample containing 15.58
g/T Au. This association suggests an epithermal system with a possible magmatic
connection. The epithermal nature of the system is also supported by the local
presence of rhythmically banded chalcedonic to sugary quartz, and coarser
crystalline quartz in some of the higher grade veins. This association may also
provide another geochemical tool for identifying the more important mineralized
vein zones.


Based on these encouraging results the Company plans to complete an MMI soil
sampling program on the Rio Negro Property, with a possible follow-up ground
magnetics survey. This work, coupled with our recent mapping and ongoing rock
chip sampling, is expected to generate drill ready targets at Rio Negro later
this year.


VENECIA

The Company's Venecia gold-copper porphyry project is contiguous with the west
side of Bellhaven Resources' La Mina property, and lies approximately 10
kilometers north of AngloGold's Quebradona gold porphyry. Venecia is hosted
within the productive Cauca - Romeral structural belt, which as reported in the
Company's press release of December 18, 2008, hosts more than 30 million ounces
of combined historic gold production and reported resources, including La Colosa
(AngloGold), Marmato (Medoro), Yarumalito (Colombian Mines), Quebradona
(B2Gold), La Mina (Bellhaven), Titiribi (Sunward), Buritica (Continental Gold)
and others. The geology at Venecia is similar to most other porphyry systems on
the Cauca-Romeral belt including both Quebradona and La Mina, and consists of a
series of late Tertiary stocks that are intrusive into the older Combia
volcano-sedimentary sequence.


Colombian Mines has completed a conventional soil geochemical survey with a
nominal sample spacing of 250 meters that covers most of the eastern half of the
Venecia property. Concurrently, Company geologists collected rock chip and
channel samples where possible. The soil survey identified three large
coincident gold and copper anomalies, while surface rock sampling returned
numerous highly anomalous samples with values up to 3.8 g/T Au and 0.6% Cu over
a 1 meter channel width in an area of very sparse outcrop. A Venecia project
description with maps on general geology and geochemistry will be updated on the
Company website in the near future.


Sample Collection - Quality Control - Quality Assurance

The Company's exploration samples are collected in accordance with accepted
industry best practices. Samples are collected and transported under the
supervision of Company personnel to SGS Laboratory's Medellin sample preparation
facilities and analyzed at SGS's Lima, Peru laboratory (ISO9001:2000). For all
rock and drill samples, gold was analyzed by fire assay with an ICP/AES finish,
and silver and base metal analyses were determined with ICP/AES techniques. As
standard procedure for core and rock channel samples, the Company conducts
routine QA/QC analysis on all assay results, including the systematic
utilization of certified reference materials, blanks, field duplicates, and
umpire laboratory check assays. Rock channel results in this news release
represent approximate true widths. All MMI samples are collected by trained
field technicians and the samples analyzed by SGS at their Lima, Peru facility.
For MMI soil sampling, duplicate samples are collected at a rate of 1 in 30.
