Exploration took place from 1988-2002, a period during which the silver price ranged from $4-6 per ounce and there was little incentive to evaluate the geologic potential for higher grade silver zones, similar to those which existed in the vein system mined by previous underground mining operations.
Equally important, no significant studies were completed to fully evaluate the production potential of silver with extensive metallurgical testing.
Vista's drill plan is focused on examining the potential for expansion of the bulk mineable resource estimates already identified and the high grade potential of the underground minable vein systems in the district and in the lower zones of the historic mine operations.
Following the drilling program, Vista plans to commence a systematic metallurgical testing program so that the economic potential of the deposit can be evaluated.
The style of mineralization is similar to that of Primero Mining's Tayoltita operation located 60 kilometers to the southeast with a historical production of greater than 9 million ounces of gold and 600 million ounces of silver.
Vista owns 28 contiguous claims in the Guadalupe district with a total area of 6,790 hectares (16,779 acres).
