Impact Silver Corp. Commences Construction Of Third Mine And
Increases Production
======================================================================

IMPACT Silver Corp. ("IMPACT") is pleased to announce both the
commencement of construction activities at the new high-grade silver
Chivo Mine as well as an increase in production throughput to 300
tonnes per day ("tpd") at the Royal Mines of Zacualpan Silver District,
Mexico.

CHIVO MINE

Permitting is now complete and groundbreaking has begun to put the new
Chivo Mine into production. Chivo will be the third producing mine at
the Royal Mines of Zacualpan Silver Project and the second put into
production by the IMPACT team. The Chivo Mine is located in the
central part of the district. Underground access is expected to reach
the main Chivo Silver Shoot in late October. Once there, development
work will commence to open multiple headings on the mineralization,
creating development muck that will be processed in the mill.
Production from stoping will commence at 60 tpd in early 2008 and will
significantly boost IMPACT's overall silver production.

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 assayed 1,095g/t silver and 0.38g/t gold across
1.25m true width ("TW") in the workings and 2,640g/t silver and 1.36g/t
gold across 0.85m on surface.

Two subsequent drill programs consisting of 18 holes returned
highlights of 937g/t silver, 0.35g/t gold, 1.88% zinc and 0.75% lead
across 2.7m TW (Drill hole Z-06-10) and 378g/t silver, 0.30g/t gold,
4.25% zinc and 1.76% lead across 4.7m TW (Drill hole Z07-03). (See
IMPACT news releases dated October 12, 2006 and July 12, 2007.) This
drilling outlined a silver shoot measuring 100m horizontal by 220m down
dip which remains open for expansion to the northeast and southwest.
The program also discovered a possible second shoot, the Chivo
Northeast Zone, with four holes which returned highlight results of
451g/t silver, 0.43g/t gold, 3.86% zinc and 1.32% lead across 1.4m TW.


As part of the ongoing 10,000m drill program, surface drilling is
further outlining extensions of the Chivo Northeast Zone and several
nearby parallel veins. Underground drilling to further expand the main
Chivo Silver Shoot is being done by IMPACT's wholly-owned underground
drill. IMPACT geologists believe that the cluster of veins in the
Chivo area will form the basis for another significant mining hub in
the Royal Mines of Zacualpan.

THREE HUNDRED TONNES PER DAY PRODUCTION ACHIEVED

IMPACT's two existing mines, the Guadalupe and Gallega Mines, have
achieved consistent production of 300 tpd, more than double the
original production level of 145 tpd when the Royal Mines of Zacualpan
was purchased by IMPACT in January 2006. It is IMPACT's goal to
achieve production of 500 tpd before the end of next year. Production
increases are anticipated to come from the Chivo Mine when it comes on
line, expanded production in the other existing mines and two other
zones being assessed for near term production.

Frederick W. Davidson, President and CEO of IMPACT said: "This is an
important milestone within our overall growth strategy. In 18 months
we increased production from 145 tpd to 300 tpd. We're making
excellent progress on the ground towards our near term goal of ramping
up production at the Royal Mines of Zacualpan to 500 tpd."

was NTW size (5.71cm diameter) and BTW size (4.20 cm diameter). Half
core samples were collected with a rock saw, tagged for identification
and securely stored at the IMPACT base camp until shipment. Chip and
channel samples were collected from cleaned rock faces in old mine
workings and from bedrock outcrops over a continuous representative
interval using a moil and hammer. A total of 5% assay standards and
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 2mm 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 analysed for an additional 30
elements by ICP spectrometry.

IMPACT Silver Corp. is a silver focused mining and exploration company
with a producing silver operation at the Royal Mines of Zacualpan,

million shares of IMPACT.
