[{"type":"text","content":"\nIMPACT Compiles over 1,200 Historical Mine Workings and Successfully Launches GIS Database at Zacualpan\n\n\n Aug. 11, 2009 (TheNewswire.ca) -- In 2006 IMPACT Silver Corp (TSXV:IPT) (\"IMPACT\") initiated a district wide compilation of the historical exploration and mining information on the 272 km2 Royal Mines of Zacualpan Silver District and the adjacent 200 km2 Mamatla District located in the Mexican silver belt. An experienced team has been assembling and re‑discovering historic data over this large claim holding that has been mined for silver since the early 1500's. The historical information is considerable, with maps occupying several rooms at the mine site. Although work on this GIS (Geographic Information System) database is ongoing, selected areas currently have a sufficient degree of completeness to direct modern exploration programs of prospecting, mapping, trenching, sampling, and drilling.One important aspect of the GIS database work is the compilation of historical mine and exploration workings. To date 1,274 historical workings have been located and entered into the GIS database with prospecting and researching old maps adding on average 10-15 more per week. More specifically, the GIS data compilation categorizes the old workings into type and size as listed in the tables below and also tabulates information concerning past production, rock conditions, sampling results, geology and other historical information as may be available. Summarized below is the breakdown by type of historical workings compiled to date:\nZACUALPAN AND MAMATLA DISTRICTS - OLD MINE WORKINGS \nTYPE OF WORKING NUMBER \nUnderground Adits, Drifts and Crosscuts 720 \nShafts 133 \nOpen Pit Mines 15 \nProspect Pits Trenches 359 \nUnspecified Workings 47 \nTOTAL 1,274 \nHistorically over the past 480 years, mines in Mexico have been closed for a variety of reasons unrelated to the exhaustion of reserves. Common reasons include flooding as reliable pumps were often not available to allow mining below the water table, political unrest, the sinking of ships carrying critical supplies from Spain, periods of exorbitant taxes and low silver prices.As these old workings are re-discovered by IMPACT field crews, they are rehabilitated (if possible), mapped and sampled in a systematic manner to generate new drill targets.
