VANCOUVER, May 3 /CNW/ - Emgold Mining Corporation (EMR-TSX-V) ("the
Company") is pleased to report that integration of historic mine maps and
other geologic data into a three-dimensional computer model from data
collected during the time the Idaho-Maryland Mine was an active gold mining
operation from 1851 to 1956 continues to indicate the presence of high-grade
gold exploration targets at the Company's Idaho-Maryland Gold Mine in Grass
Valley, California.
When completed, this comprehensive model will include geologic units,
faults, veins, underground workings, assays and gold resources developed from
the historic data, and geologic information from Emgold's two surface drilling
programs. The data, which includes 220,000 feet of historic core drilling,
24,800 feet of core drilling conducted by Emgold, 36,000 assays, and 4,000
mine maps, is being digitized and entered into the MineSight(R) three-
dimensional modeling software program. All work is under the supervision of
Mr. Robert Pease, Professional Geologist (California), Chief Geologist for the
Idaho-Maryland Project and a Qualified Person in accordance with National
Instrument 43-101.
Historic mine maps detailing operations from 1945 to 1947 demonstrate
that high-grade intercepts were discovered on the Idaho 23 Vein in the
northeastern section of the Idaho mine at the 2000-foot level. In one area, a
drift 350 feet in length was excavated and 61 samples were taken along this
vein that had weighted average grades of 1.0 ounce per ton gold. A raise was
excavated approximately 100 feet up the vein and 17 samples were taken up the
raise that had weighted average grades of 1.8 ounces per ton. In addition, a
winze was excavated approximately 100 feet down the vein and 21 samples
produced weighted average grades of 0.75 ounce per ton. The total weighted
average grade for all samples taken was 1.0 ounce per ton, and the range in
assays was zero to 14.1 ounces per ton. A small amount of stoping (about
500 tons) was done along this part of the Idaho 23 Vein, but no other
production was undertaken. This area became known as "The Rose Garden". A
table of representative grades from the raise, winze and the Idaho 2000 level
drift is shown below:

The geology of this zone includes diabase dikes and ankerite (altered
serpentinite), with gold being present in a quartz vein situated between the
Weimar, H, L, and K faults. The sample thicknesses, including those presented
in the table, were descriptions written on the historical assay maps. The
historical information indicates that the Idaho 23 Vein widths should be
adequate for mining. It is also important to note that based on the Company's
most recent NI 43-101 Preliminary Assessment Technical Report on the Idaho-
Maryland Mine (dated November 22, 2004), the historic average true thickness
of veins within the Idaho-Maryland ranged from 8.1 ft. to 70.7 ft.
It is important to note that this assay data is historical in nature, and
further exploration is required to verify the accuracy of this data. The
Company believes this information is useful as an indication of the
exploration potential of the Idaho-Maryland project and is planning additional
surface and underground exploration to further define its understanding of the
historic mineralization as well as other new targets identified from the
modeling activities.
Emgold developed the "Rose Garden" high-grade zone into a gold resource
block in 2003 using the historic data. The block contains an indicated
resource estimated to be 14,900 tons of 0.54 opt (8,027 ounces of gold), and
an inferred resource estimated to be 21,700 tons of 0.51 opt (11,161 ounces).
These were cut grades with no mine call factor. These resources are included
in the resource estimate presented in the November 2004 Preliminary Assessment
Technical Report prepared by AMEC Americas Limited. Since the mine workings
are not accessible, Idaho-Maryland geologists have not verified the sample
results used to delineate the resource block, but the historic assay map data
is felt to be a reliable indicator that this vein is open along strike and
dip. The gold resource block may be tested in the future once the planned
underground exploration and development program has commenced at the Idaho-
Maryland.
