Impact Silver Extends Strike Length Of Chivo Mine; Drills 12.3 Meters Of 6% Zinc And 2% Lead
|IMPACT Silver Corp. ("IMPACT") is pleased to announce that continued drilling on extensions of the Chivo Mine has significantly extended the trend northward and has intersected strong mineralization.|
The Chivo Mine, located in the Royal Mines of Zacualpan Silver District in Mexico, achieved commercial production in early 2008 based on successful exploration over the past two years. The mine was put into production based on 21 drill holes and sampling of old workings. This news release reports on an additional five holes drilled on the northern extension of the Chivo Zone. Beyond these results, there have been a further 20 holes completed on both the northern and southern extensions of the Chivo Zone. Assays are pending. The main Chivo Zone remains open in all directions for further expansion.
Highlights of the additional holes drilled on the northern extension of the Chivo Zone are as follows:
The deepest holes on both these sections were the widest and highest grade intersections leaving the zone open for expansion to depth and to the north. Drill hole Z08-49 was drilled at depth on the same section as drill hole Z07-08-11 (see IMPACT news release dated July 12, 2007) and extended the zone of mineralization an additional 50 meters down dip. Drill holes Z08-45 through Z08-48 were drilled on a new section 30 meters north of any previous drilling.
On a deposit scale, the Chivo Zone is showing itself to be increasingly zinc and lead-rich to the north where these holes were drilled and silver-rich to the south where IMPACT has recently completed additional drill holes (assays pending).
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 TW 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 TW (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 TW (Drill hole Z07-03) (see IMPACT news releases dated October 12, 2006 and July 12, 2007). To date, 41 drill holes have been completed on the zone (assays pending for 15 holes) and additional drilling is planned to begin in May 2008.
Fred Davidson, President of IMPACT Silver, states, "Chivo continues to deliver wide zones of high grade mineralization with each step out in the drill grid. This drilling success is rapidly growing this zone and nearby zones to where we are now looking at the Chivo area as a second major mining hub in the district. With the huge land package we control and the exploration successes we are having throughout the area, we envision a future with multiple mining and processing centres spread over the entire district."

Drill core was NTW size (5.71 cm diameter). Half core samples were collected with a rock saw and tagged for identification. 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. 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.
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.
