Silverado releases mineral resource estimates for its Ester Dome property in Alaska

    VANCOUVER, July 31 /CNW/ - Silverado Gold Mines Ltd. (the "Company")
(SLGLF OTCBB, SLGL Frankfurt, ), is pleased to announce that
it has received a completed mineral resource estimate for its Ester Dome
property, located about 10 miles west-northwest of the community of Fairbanks
in interior Alaska, from Thomas K. Bundtzen ("Bundtzen") of Pacific Rim
Geological Consulting Inc., the independent mining consultant commissioned by
the Company to prepare a NI 43-101 Technical Report. The Technical Report,
dated July 30, 2008, was filed today on SEDAR and is available at

    Mineral Resource Estimate

    Since 1983, mineral resource estimates have been prepared by the Company
relating to Ester Dome near Fairbanks, Alaska. Bundtzen was given access to
all exploration data previously acquired by the Company to determine the
current resource estimates of lode gold on Ester Dome. The table below
summarizes the mineral resource estimate for the Ester Dome property
(effective July 11, 2008):

                   Cut-Off Grade      Quantity        Grade         Metal
    Category        (oz/ton Au)         (ton)      (oz/ton Au)     (oz Au)
    Indicated           0.08           631,600         0.21        126,700
    Inferred            0.04         2,553,400         0.08        214,100

    Notes :

      -  Mineral resources which are not mineral reserves do not have
         demonstrated economic viability. The estimate of mineral resources
         may be materially affected by environmental, permitting, legal,
         title, taxation, socio-political, marketing, or other relevant
         issues. There has been insufficient exploration to define these
         inferred mineral resources as an indicated or measured mineral
         resource, and it is uncertain if further exploration will result in
         upgrading the inferred mineral resource to an indicated or measured
         mineral resource category.

      -  Rounding may result in some discrepancies.

      -  No processing recovery factors have been applied to these resource

      -  The unit ton refers to short tons.

    All reclamation work on Ester Dome has been completed and the Company is
working towards completion of the closure of the Grant Mill tailings pond.
This pond, which is filled to capacity with tailings, will be capped and
decommissioned after a final approval of the tailings pond closure plan is
received from the Alaska state regulatory authorities.

    Assumptions and Methods

    Bundtzen included the following steps during calculation of the indicated
and inferred resources at Ester Dome:

      -  examination of the Company's Ester Dome and Eagle Creek properties
         in 1980 - 82, during 1995, 2004 and 2008;
      -  database compilation and data validation;
      -  geological interpretation and modeling;
      -  compositing assay intervals to a common length;
      -  determination of average material density for both lode and placer
      -  analysis of grade variability;
      -  polygonal estimation of grade by the compositing of sample assay
         information taken within designated widths and lengths of
         mineralized zones;
      -  assignment of appropriate cut off grades, the lowest grade that can
         be mined economically;
      -  classification of confidence in the estimates with respect to CIM
         (2005) guidelines; and
      -  mineral resource tabulation and validation of the resource estimate.

    To arrive at the resource estimates on Ester Dome, Bundtzen used data
from 18,705 feet of trenching, 11,758 feet of overburden geochemical sample
drilling, 58,396 feet of rotary drilling, 60,011 feet of surface diamond
drilling, 3,740 feet of underground diamond drilling, and 7,917 feet of drift,
raise, and sub-drift activities (in the Grant Mine). Specifically, 53 drill
core holes totalling about 55,000 feet were the most important data source for
both the indicated and inferred categories of gold resources on Ester Dome,
most of which were derived from drilling the O'Dea deposit at the Grant Mine.

    Data Verification

    Bundtzen used exploration data stored in the Company offices on Ester
Dome. During October 2004, he examined core from American Copper Nickel
Company ("ACNC") drill program conducted during 1991 - 1992 in a core shed
behind the Grant Mine complex. The Grant Mine and mill complex is situated on
the southeast flank of Ester Dome, about 8 miles northeast of Fairbanks,
Alaska. Bundtzen also was on site during the 1991 drill program at the Grant
Mine. He also worked underground at the Grant Mine as a geologist then
employed by the Alaska Department of Natural Resources during 1981 - 1982
while the Grant Mine was in development, and has a sound understanding of gold
grades and character of the ore body. Bundtzen also observed drilling activity
at the Ethel-Elmes operation prior to its development in 1988 - 1989. Although
Bundtzen did not conduct independent check samples from the Ester Dome drill
programs, he assessed the analytical integrity of the sample data. Two
analytical facilities were used during past drill programs. The Company used
ACME Analytical in Vancouver. ACNC used Chemex Labs in Vancouver. Both
companies submitted prepared standards, which were inserted every 15th or 20th
sample interval. ACNC also twinned certain drill holes previously drilled by
the Company. Mr. Bundtzen's review of such results did not reveal any
reportable anomalies. During the 2004 review, he reviewed the techniques and
certified assay reports generated by the Company, including the gravimetric
'metallic assay' research work done at the Grant Mine.
