    VANCOUVER, March 1 /CNW/ - 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 No. 1 Vein, which produced one million
ounces of gold from one million tons over 30 years, and the Idaho No. 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.

    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.
