SILVER SHIELD REPORTS FIRST RESULTS FROM DIAMOND DRILLING AT
JARIPO CONCESSION IN MEXICO
Sep. 15, 2010 (Canada NewsWire Group) --
UP TO 7% ZINC and 360 g/t SILVER
BURLINGTON, ON, Sept. 15 /CNW/ - Silver Shield Resources Corp.
(TSXV - SSR) ("Silver Shield" or "the Company") today announced the
results from its diamond drill program at its 2,954 hectare
"Jaripo" property the State of Michoacan, Mexico.
A total of
1,503 metres was drilled in 12 holes drilling program at Jaripo was
designed to trace the mineralized zone over a 400 metre interval
near the main area of historic mining, and also to investigate
the area to the south where numerous other old mine workings are
located. Historic mining is quite shallow in depth, not exceeding
40 metres and it was expected that
mineralization would continue
to depth. There is no record of previous diamond drilling at the
property.
The Jaripo Concessions are geologically located within the Huetamo
Subterrain in Michoacan State, and cover a generally north-south
trending mineralized structure located at the thrust fault boundary
between a package of sedimentary rocks and limestone. Intruded
between theses rocks is a felsic dike of up to 10 m wide.
Mineralization is generally hosted within a zone of carbonate
veining that flanks the east contact between the dike and the
sediments and within the sediments.
Drillholes JAR-01 and 02 successfully located the mineralized zone
north of the area of previous mining and intersected good Lead/Zinc
and Silver values, with the width of 4 metres in Jar-02 being much
wider than expected. Drillholes JAR-02 to 06 are located around the
area of historic mining and below. In these holes numerous
mineralized intervals were found surrounding the primary vein
structure.
This suggests that while the
mineralization may be more complex than expected,
the potential for significantly more
mineralization than expected is high. While widths were
commonly in the 1 - 2 metre range, a mineralized interval of 13
metres was found in hole JAR-04 and a mineralized interval of 6.25
metres was found in hole JAR-06, also supporting that a larger
tonnage may ultimately be found. Lead grades were generally
below 1 % but ranged up to 3.6 %. Zinc grades were more consistent
and ranged between 2 and 7%. Gold values were low, as expected, but
Silver provided significant value with many intervals over 100 g/t
and some narrow intervals were over 300 g/t. Mr. Tim Towers,
President and CEO of Silver Shield stated "At this time of silver
price appreciation we are extremely pleased with the assay results
to date and we look forward to further development of the silver
resource at Jaripo."
The drilling program has to date, successfully demonstrated the
existence of economically interesting grades of Silver-Lead/Zinc
mineralization on the Jaripo Concessions with greater widths and
more mineralized intervals than expected. Drilling was limited to
approximately 100 metres vertically so a great deal of potential
remains to be explored. Additional drilling is required to further
develop the understanding of the mineralization before a Resource
Estimate can be produced.
Initial Results from the first 6 of 12 drillholes follow.
Additional assay results are pending from Drillholes JAR-07 to 12,
and will be released in the near future.

Drill core is logged, and samples saw split, on site. One half of
the NQ or HQ diameter core was shipped to SGS Minerales-Durango. in
Durango, México, a member of SGS Group of Companies, certified
annually in compliance with the ISO 9001:2000 Guidelines for
Quality Management. All samples received are prepared for analysis
and finished in Durango without shipment to another facility. The
entire sample is thoroughly dried, reduced to (greater than)80% -10
mesh by jaw crusher. A 250-300 grams subsample is then split and
pulverized to (greater than)90% -150 mesh with a pulverizing mill.
Tested barren sand is used as to clean the equipment between each
sample.
Aqua Regia digestion and ICP-AES, is used to determine silver and
other metals content (LDL Silver 0.1 ppm) on a 1 g sample. Gold is
determined by Fire Assay-AA Finish (LDL Au 10 ppb) on a 1 Assay Ton
sample. For Overlimit assays gold is determined by a 30 g Fire
Assay - Gravimetric finish to LDL of 0.005 oz/ton or 0.15 g/t, and
silver is determined by 30 g Fire Assay - Gravimetric finish to a
LDL of Ag 0.5 oz/ton or 15.5 g/t Internal Lab Quality Control
consists of a repeat of every tenth sample, and for every 20
samples run, a standard and a blank sample is also analyzed. Silver
Shield will also be instituting a QA/QC program consisting of
Certified control standards, and coarse field blanks to be inserted
into the sample stream. A program of analysis of duplicate samples
at other labs will be undertaken.
