Emgold Discovers Additional Tungsten Mineralization
In Trenches At Stewart Property, Salmo, B.C.
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 th at 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. Table 3 summarizes results of analyses from trenching on the Free Silver 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.
