Prospero Silver Corp.: Rock-Chip Sampling Yields Highly Anomalous Gold in the Petate West/Apartadero Target Zone, El Petate Project, State of Hidalgo
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/21/13 -- Prospero Silver Corp. (TSX VENTURE: PSL) ("Prospero" or the "Company") is pleased to announce the results of 360 rock chip samples obtained from the Petate West and Petate East target zones of its 6,000 hectare El Petate project. The Apartadero target is part of the Petate West zone, measuring 1.3 km long and up to 200 meters wide and has shown the most anomalous gold geochemistry to date in jasperoid outcrops and float. Mapping of the Petate West zone shows northwest and east-west trending silicified zones associated with andesitic dikes with the same orientation (Figure 1). Mapping and sampling have to date identified the La Escoba, Apartadero and and Tecolotes silicified reefs. Other as yet unmapped reefs are anticipated west of the Apartadero reef and in the southern extension of the Petate West zone (see attached maps). The property boundary lies outside the area of the figures.
The highlights of the Apartadero geochemistry include:
While the Apartadero geochemistry is highly anomalous in gold in its southeast extension, the data to date from the Petate East geochemistry is showing proportionately higher silver geochemistry as follows:
Other Target areas.
La Escoba areas in the northwest portion of the district is divided into Escoba North, Escoba Central, and Escoba south silicified trends. These are characterized by more subtle precious metal and pathfinder-element anomalies, with gold highs in the 0.1 to 1 ppm range, silver highs under 5 ppm, and mercury highs under 5 ppm.
The Tecolotes area in the southwest sector of the district also exhibits significant highs in Au-Ag-Sb-Hg-As (Figures 2 to 4).
Samples obtained from the reconnaissance sampling program represent chip-grab, chip-channel samples, as well continuous channel samples, either in outcrops or in jasperoid boulders and fragments within float. Most samples were obtained along lengths of 1.0 to 1.5 meters.
Next-step activities for the Petate project:
The Apartadero area (in the Petate West zone), and the Petate East areas are prime targets which require a trenching program in zones where the best precious metal anomalies occur, particularly along the northeastern margin of the Apartadero trend which hosts discontinuous outcrops of dikes. Channel sampling in the trenches should provide a better understanding of the length, width and grade of the mineralized zone(s).
Additional reconnaissance mapping and sampling is required west of the Apartadero area and in the southwestern sector of the district.
The Tecolotes area is believed to host several silicified reefs yet to be mapped and sampled in more detail.
The geology of the project is characterized by an anticlinorium/dome of the Mesozoic fold belt of the Sierra Madre Oriental. All mineral occurrences are hosted in the El Abra limestone of Lower Cretaceous age. A north-south trending remnant of the Upper Cretaceous clastics of the Mendez Formation is as yet un-eroded in a recumbent syncline between the Petate West and Petate East zones (see Figure 1). Scattered outliers of overlying andesites of the Tertiary Pachuca Group do not host alteration or hydro-thermalism, thus suggesting the hydrothermal system is more akin to the age of the Zimapan skarn/replacement type deposit (approx. 42 Ma), than the age of the Pachuca vein deposit (approx. 23 Ma).
In summary, the Apartadero zone highlights stronger gold values associated with Ag-Hg-Sb-As, whereas the Petate East areas are characterized by stronger silver values in association with Au-As-Ba-Fe-Mn. These preliminary results show strong geochemical signatures in the Apartadero and Petate East target areas, including multi-ppm values in gold at Apartadero, and greater than 50 ppm Ag at Petate East. Given the length of the silicified reefs, the Petate project area represents a robust system with excellent potential to host a preserved replacement type deposit at depth with elevated precious metals.
Fluid inclusion petrography indicates the fluids associated with deposition of crystalline quartz are relatively low temperature and salinity (130 degrees C to 230 degrees C; 0-3.0 wt.% NaCl equiv) indicating the surface exposures across the project area correspond to the upper portions of a preserved mineralized system at depth.

Samples were collected by Company employees and are shipped in sealed bags to ALS-Chemex Laboratory preparation facilities in Zacatecas City. Sample pulps are shipped to ALS-Chemex Laboratories in North Vancouver, B.C. for analysis. All samples were assayed by multielemental ME-ICP41, and gold ICP21.
