Emgold Mining Corporation (EMR-TSX Venture) (the "Company"
or "Emgold") is pleased to announce trenching results from its
2007 exploration program on the combined Stewart and Jazz properties,
located near Salmo, B.C. (see Emgold's June 12, 2007 news release). Emgold
is very encouraged by the results of this trenching program.
The focus of the 2007 exploration program at Stewart/Jazz was to test three
exploration targets through trenching and diamond drilling. This news release outlines the
trenching results for the exploration program. Emgold completed a total of
28 trenches on the three zones of mineralization within these properties.
The Stewart Zone is a molybdenum exploration target, the Arrow Zone is a
tungsten exploration target, and the Free Silver Zone is a silver-lead-zinc
exploration target.
Sampling Protocols
Trenches were excavated across geological trends of mineralization in
bedrock utilizing a track mounted backhoe. Debris was cleaned off of
bedrock by hand tools prior to sampling. Bedrock samples were taken along
measured lengths using hammer and chisel, with continuous equal-sized
representative chips taken along the trench. Samples were placed into
labelled bags at the site. Sample batches were shipped directly to Acme
Labs Ltd. (Acme) in Vancouver for assay using standard analytical
procedures. All sample preparation was done at the laboratory by Acme
staff. Periodic check samples were submitted, by the company, to assorted
accredited laboratories located in the Vancouver area. Samples were
analyzed for 30+ elements by ICP methods, including molybdenum, tungsten,
zinc, gold and silver. Results are presented in the tables below. Trenches
not listed in the tables had low assay values that were near or below
detection limits.
Stewart Zone
The Stewart Property was previously explored and drilled by Shell Minerals
and Selco Inc. in the early 1980's. The exploration programs initiated by
these companies focused on molybdenum, delineating three breccia phases
that contained significant mineralization. In late 2005, Emgold conducted a
500 metre diamond drill program to test the historic drill results as part
of a due diligence program. That program successfully verified the presence
of mineralization (see Emgold's November 28, 2005 news release). This
year's trenching on the Stewart Molybdenum Zone (trenches 07ST-01 to
07ST-06) was designed to test for extensions to the high-grade breccia
zone.
The current trenching program tested for molybdenum mineralization in the
surrounding granitic host rocks and along the margins of the known breccia
zone perimeter. A total of 96 rock chip and isolated grab samples were
collected from 291 metres of bedrock in six trenches. Significant
molybdenum mineralization was seen in Trench 07ST-01, which intersected 3 metres
grading 100.44 ppm molybdenum. The other trenches had generally low
molybdenum values, but three contained elevated tungsten levels. In
addition, trench 07ST-05 had a 3 metre chip sample grading 1445.2 ppb gold.
The results are summarized in Table 1 below:

Arrow Zone
The Arrow tungsten zone was discovered by hand trenching in the early
1940's. Previous sampling of the hand trenches by Emgold showed encouraging
values of tungsten and zinc from skarny sedimentary rocks. The current
excavator trenching program (trenches 07ST-07 to 07ST-20) was designed to
better expose mineralization in the historic hand trenches to allow for
systematic chip sampling and geologic mapping. A total of 178 samples were
collected from 496 metres of trenching, with significant values of tungsten
being found over widths of two to three metres. High tungsten values were
generally confined to skarn zones in sedimentary rocks adjacent and
peripheral to underlying granitic dykes and sills. In some instances
elevated tungsten values correlated well with elevated zinc values. Table 2
summarizes results of analyses from trenching on the Arrow Zone:

Free Silver Zone
Trenching at the Free Silver zone (trenches 07FS-01 to 07FS-08) uncovered
shear-hosted vein mineralization, including sphalerite and galena. Trenches
were placed within or close to the margins of a granitic stock in contact
with sedimentary rocks over a strike length of approximately 600 metres. A
total of 86 samples were taken from 224 metres of trenching, resulting in
encouraging values of up to 5.92% lead, 2.71% zinc, and 46 g/t silver.
Exposures in the trenches indicate true vein widths of one to three metres.

zone:

Drilling Programs
In addition to the trenching work, Emgold initiated a diamond drilling
program on the Stewart/Jazz property this year to further define molybdenum
and tungsten mineralization at the Stewart Molybdenum Zone and the Arrow
Tungsten Zone. A small diamond drilling program was also begun on the Rozan
property, located near Nelson BC, to test extensions of a high-grade
gold-bearing quartz vein previously drilled by Emgold (see Emgold's
December 4, 2001, news release). These drilling programs are currently in
progress and will be completed by the end of year 2007. Results are
expected by the end of Q1 2008.
