March 1 /PRNewswire-FirstCall/ -- Emgold Mining Corporation (EMR -
TSX-V) ("Emgold" or the "Company") is pleased to report that the
total inferred mineral resources at the Idaho-Maryland Mine in
Grass Valley, California, have now surpassed one million ounces of
contained gold. The inferred total resource using the historic Mine
Call Factor ("MCF") of 1.44 includes 43,000 tons ("t") with an
average grade of 0.93 ounces of gold per ton ("opt") to contain
40,000 ounces of contained gold. An additional 5,000t grading 2.05
opt increases the total inferred contained gold to 1,002,000 ounces
of contained gold. The mine also has a measured and indicated
resource consisting of 1,666,000t grading 0.28 opt using the MCF to
contain 472,000 contained ounces as presented in the Company's
November 2004 Technical Report prepared by Amec Americas Ltd. All
resources are summarized in the table below. Sixteen new gold
resource blocks have been identified using the Company's
computerized models increasing the total number of resource blocks
to 216. Each of the 216 resource blocks is a target for further
surface and underground exploration. Approximately 70 percent of
the new resources are from primary veins including the Idaho # 1
Vein, which produced one million ounces of gold from one million
tons over 30 years, and the Idaho # 3 Vein. These veins show
remarkable continuity down-dip; continuous structures that were
mined to depths of over 2000 feet. In addition, the majority of the
new inferred resources were identified at the deeper levels of the
mine where historic mine operations excavated drifts in veins and
detailed sampling was conducted to plan future mining activities.
Mining of the veins between the drifts (termed stoping) never
occurred because stoping of primary and secondary veins essentially
ended at the Idaho 2000 mine level. However, the mine levels below
the 2000 level were developed and sampled in preparation for future
mining. Computer modeling of historic assay data was completed last
year and is being used to determine the sites of potential new
resource blocks and exploration targets. In addition to the new
resources, more than two hundred new exploration targets have been
found. Most targets are along extensions of existing veins. The
exploration targets do not meet the vein thickness criteria
required to be classified as resource blocks, but these areas do
indicate the presence of gold mineralization and will be very
important guides to identify additional gold resources in the
future. 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. In a Preliminary Assessment Technical
Report published in 2004, AMEC reviewed and updated the
requirements for establishing mineral resources at Idaho-Maryland
Mine. Some of the original criteria are: a) the blocks must have a
minimum true thickness of 3 feet, b) the cutoff grade is 0.1 ounce
per ton of gold, and c) the resource blocks are limited to certain
length and height dimensions. The updated requirements that have
been applied to these new resources are: a) the mine call factor
can be used on all resources derived from sampling of development
drifts, b) the mine call factor cannot be used on any resource
blocks developed from drillhole data, and c) resources are to be
reported using uncapped gold grades. The following table is a
summary of all mineral resources, including the new ones, for the
Idaho-Maryland project. Idaho-Maryland Project Gold Mineral

1. MCF = Mine Call Factor (not applicable to Waterman Group
resources). 2. Inferred resources are divided into A (historic data
and mine call factor applied) and B (from 2003-2004 data and no
mine call factor applied). 3. Idaho-Maryland measured resources are
split into two categories: 1. the Eureka, Idaho, Dorsey, and
Brunswick Groups, and 2. the Waterman Group (stockwork/slate type
ore). 4. New inferred resources include 40,000 ounces with MCF (A),
and 10,000 without MCF (B). The November 2004 Technical Report
defines the Mine Call Factor ("MCF") used in determining the gold
grade based on historical assay data for the Idaho-Maryland Mine.
Historically, the planned mill feed tonnage and gold grade rarely
matched the actual results. This was a result of a variety of
factors that could be resolved by adjusting the planned production
by a constant number. This number or factor is called the
multiplier factor or mine call factor. Commonly, deposit types like
the Idaho-Maryland typically under-predict the gold produced. The
report also states, "Two factors were calculated: a "model"
(underground sampling) to "mine" (muck car sampling) factor, equal
to 1.21, and a "mine" to "mill" factor, calculated to be 1.19. The
total Mine Call Factor is equal to 1.44. AMEC reviewed the work
done by James Askew and Associates and agrees with their results.
The use of the Mine Call Factor can be used to establish a
relationship between the historic underground channel samples and
expected production. This factor should only be used on the nuggety
vein system data. The more homogeneous slate-hosted mineralization
should not be factored at any resource category." 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. Since the mine
workings are currently not accessible, as the mine is flooded,
Idaho-Maryland geologists have not verified the sample results used
to delineate these resource blocks, but the historic assay map data
is felt to be a reliable indicator that the veins are open along
strike and dip. These gold resource blocks will be tested in the
future once the planned underground exploration and development
program has commenced at the Idaho-Maryland. Underground
exploration of the 216 resource blocks and 200 exploration targets
should commence after the Company receives its Conditional Mine Use
Permit from the City of Grass Valley. In June 2006, Idaho-Maryland
Mining Corporation ("IMMC") successfully completed Phase 1 of the
three-phase process to permit the reopening of the Idaho-Maryland
Mine. Phase 1 included the completion of the Master Environmental
Assessment ("MEA") as part of the California Environmental Quality
Act. Based on public input during the MEA process, advances in the
Ceramext(TM) technology used to make stone and ceramic tile
products from the mine waste, plus advances in computer modeling of
the historic Idaho-Maryland Mine geology and assay data, IMMC has
been revising its permit application prior to entering Phase 2 of
the permitting process referred to as the Initial Study. This will
be followed by Phase 3, the EIR process, expected to commence in
the summer of 2007 and may be completed in early 2008. For more
