Impact Drills 11,463g/t (334 oz/ton) Silver Over 0.6M (2ft) At
Chivo Mine And Expands Strike Length By 40%
=======================================================================
IMPACT Silver Corp. ("IMPACT") is pleased to announce that drilling on
extensions of the Chivo Zone has both intersected high grade
mineralization, as well as increased the strike length of the Zone by
40% to over 300 meters.
The Chivo Mine at the Royal Mines of Zacualpan Silver Project in Mexico
achieved commercial production in early 2008 based on successful
exploration over the past two years. This news release reports on
drilling conducted to establish the southern limits of the Chivo Zone.
These results, along with those announced on August 6, 2008 for the
northern extensions, indicate that the high-grade Chivo Zone remains
open for further expansion.
Assays from the new holes drilled on the southern extension of the
Chivo Zone are as follows:

These intersections were drilled on an approximate 25 meters
(horizontal) by 30 meters (vertical) grid pattern. Five other holes
drilled further south intersected low grade mineralization. This newly
discovered mineralization will be accessible by the lower Chivo Mine
adit now being excavated and expected to reach the Chivo Vein in the
fourth quarter of 2008.
During the past year, the objective of the drill program at Chivo was
to define the northern and southern limits of the Chivo high grade
mineralization, as well as down dip extensions. This work continues.
Currently, the Chivo Zone has been defined over a length of 300 meters
and a vertical depth of 250 meters by 46 drill holes, as well as
several hundred meters of underground workings. Mining widths at Chivo
are 3 meters plus. This is up from a length of 200 meters and vertical
depth of 220 meters reported earlier (see IMPACT news release dated
June 17, 2008). A recently completed computer model of the Chivo Zone
indicates two high grade shoots within the Chivo Zone separated by a
medium grade central zone. Within the plane of the vein, the high
grade mineralization rakes to the north and remains open, indicating
the potential for additional high-grade mineralization. Future
drilling from both surface and underground is planned to expand this
zone on all sides.
Chivo was discovered in 2005 when IMPACT crews found high-grade veins
in old mine workings (see IMPACT news release dated September 7, 2005).
Samples from the veins included assays of 1,095 g/t silver and 0.38
g/t gold across 1.25 meters true width. Subsequent drill programs
returned significant grades, including 937 g/t silver, 0.35 g/t gold,
1.88% zinc and 0.75% lead across 2.7 meters true width (see IMPACT news
release dated October 12, 2006). Continued exploration success lead to
a production decision and in January 2008, only 28 months from first
discovery, the Chivo Mine achieved commercial production.
Fred Davidson, President and CEO of IMPACT Silver, states, "Chivo has
become the new cornerstone of our Royal Mines of Zacualpan silver
operations. We are actively mining our best grades here and drilling
continues to expand the zone and deliver high grade results. We have
recently begun excavation of a new lower mine adit which should reach
the main vein later this year and access the high grade zones reported
here."

was NTW size (5.71 cm diameter). Half core samples were collected with
a rock saw and tagged for identification. All samples were securely
stored at the IMPACT base camp until shipment. A total of 5% assay
standards and 5% blanks were inserted into every sample shipment as a
quality control measure. All samples were shipped to the ALS Chemex
preparation laboratory in Guadalajara, Mexico, where they were fine
crushed (70% passing a 2 mm screen), pulverized (85% passing a 75
micron screen) and pulp split separated for assay by a riffle splitter.
These pulps were shipped to the ALS Chemex laboratory in North
Vancouver, Canada, where a 30 gram split of each was assayed for gold
and silver by standard fire assay and a 10 gram split was analyzed for
an additional 30 elements by ICP spectrometry.
