IMPACT SILVER ANNOUNCES NEW DISCOVERY AT THE ROYAL MINES OF ZACUALPAN
Impact Silver Corp. has made a new discovery on the San Antonio target within the Royal mines of the Zacualpan silver district. Recent drilling returned the highest zinc and lead grades with significant gold and silver mineralization encountered by Impact to date. These results are part of the 10,000-metre drill program budgeted for 2007.
The San Antonio zone is located four kilometres southeast of the Zacualpan mill. On surface, it is marked by a glory hole measuring 45 metres by three metres by 30 metres deep, two adits and a foundation for an old processing plant. The mineralized intercepts occur below the water table, which appears to have been left undisturbed by historic mining.

Drill holes Z07-16 to Z07-19 were drilled to test the southeast boundary of the system and intersected lower grades. The zone remains open for expansion to the northwest. Surface work is continuing in preparation for phase two drilling.
Vice-president of exploration, George Gorzynski, said: "We are very excited about San Antonio. After San Ramon and Chivo, this is the third discovery with near-term production potential made by our team in Zacualpan since the acquisition of the project."
George Gorzynski, PEng, and Nigel Hulme, PGeo, qualified persons under the meaning of Canadian National Instrument 43-101, are responsible for the technical content of this news release. Drill core was NTW size (5.71-centimetre diameter) and BTW size (4.2-centimetre 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 per cent of 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 per cent passing a two-millimetre screen), pulverized (85 per cent 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, 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.
