Impact Silver Updates Production And Samples 657G/T Silver Over
2.85M At The Chivo Mine
=======================================================================
IMPACT Silver Corp. ("IMPACT") is pleased to provide an update on
production with information on its new mines, Chivo and San Ramon, in
the central part of the Royal Mines of Zacualpan Silver District as
well as significant equipment purchases.
CHIVO MINE
The Chivo Mine started commercial production in January, one month
ahead of schedule, at 60 tonnes per day (see IMPACT news release dated
September 20, 2007). Underground access is via a 92-metre long
crosscut adit. With good grades and good metallurgy from the Chivo
Zone, mining has now been ramped up to 150 tonnes per day.
The first production stope was developed over a length of 60 meters in
10-meter raises. Samples from this initial 60-meter long mining stope
averaged 269 g/t silver, 0.74 g/t gold, 3.01% zinc and 1.08% lead
across a true width of 3.3 meters ranging to a high of 657 g/t silver,
0.60 g/t gold, 1.13% zinc and 0.18% lead across a true width of 2.85
meters. At the point where the access adit intersected the vein, the
rock section above the vein contained a series of additional sheeted
veins which, when combined with the main vein, averaged 220 g/t silver
across 20.1 meters including one sheeted vein which assayed 392 g/t
silver across a true width of 5.2 meters. The full extent of this wide
bulk mineable section will be further investigated as mining and
underground exploration proceed. The 60-meter section now being mined
is only a small portion of the Chivo Zone, which has now been defined
by surface drilling to be at least 200 meters in length and 220 meters
down dip. Drilling is continuing to expand the zone in all directions
and a second production stope north of the access adit has been brought
into production.
Last week, work began on a second adit to access the Chivo Zone 60
meters below the first adit. The second adit and more working faces
are scheduled to be in place by the end of the year, and will serve to
further increase 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 1,095 g/t silver and 0.38 g/t gold
across 1.25 meters true width in the workings and 2,640 g/t silver and
1.36 g/t gold across 0.85 meters on surface. Subsequent drill programs
consisting of 21 holes returned highlights of 937 g/t silver, 0.35 g/t
gold, 1.88% zinc and 0.75% lead across 2.7 meters true width (Drill
hole Z-06-10) and 378 g/t silver, 0.30 g/t gold, 4.25% zinc and 1.76%
lead across 4.7 meters true width (Drill hole Z07-03) (see IMPACT news
releases dated October 12, 2006 and July 12, 2007).
PRODUCTION PLANS
Presently the Royal Mines of Zacualpan operations are producing at 300
tonnes per day. Plans are to expand production to 500 tonnes per day
over the next 12 months mainly sourcing additional high grade mineral
from the Chivo Mine supplemented by redevelopment in the Guadalupe Mine
to source mineral from the Kena Vein area and production from the
Gallega and San Ramon Mines. To facilitate this significant increase
in production, IMPACT has budgeted $2 million towards underground mine
development, new equipment, plant upgrades and expansion of the
tailings dam. Two new scoop trams have already been received and put
into operation. These upgrades will be completed over the next eight
months and will allow IMPACT to meet its production forecasts.
George Gorzynski, P. Eng., a Qualified Person under the meaning of
Canadian National Instrument 43 101, is responsible for the technical
content of this news release. Channel samples were collected from
cleaned rock faces in mine workings over a continuous representative
interval using a moil and hammer. All samples were securely stored at
the IMPACT base camp until shipment. A total of 5% assay standards and
5% blanks were inserted into the 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 analyzed for an additional 30
elements by ICP spectrometry.
IMPACT Silver Corp. is a silver focused mining and exploration company
operating in Mexico with a producing silver operation at the Royal
Mines of Zacualpan, the 200-square-kilometer advanced Mamatla Silver
District and a portfolio of projects with a producing mill at
Zacatecas.
