New Skarn Zone Includes 11 Meters Of 143 G/T Ag And 1.63% Cu At San Luis Del Cordero, Durango Project
|Prospero Silver Corp. (TSX-V: PSL) ("Prospero" or the "Company") is pleased to announce the results from the first two diamond drill holes on its San Luis del Cordero ("Cordero") silver project. Drilling targeted a new mineralized skarn zone buried under alluvium cover located 500 meters east of the historic Sta. Rosa Mine. Results are as follows and include an earlier shallow discovery hole:|
Note: true widths are estimated to vary not more than 15% from intersected widths.
These intercepts differ from earlier more structurally controlled vein-type styles of mineralization in the district such as those in the historic Sta.Rosa and India Bonita veins. The two new intercepts are dominated by prograde grossularite calc-silicate-chalcopyrite, and retrograde quartz-chalcopyrite-tetrahedrite-sphalerite bearing mineralization, and are more characteristic of the upper portions of a higher temperature core zone of a skarn-type deposit. The calc-silicate zone at the explored depths is located within hornfels recrystallized from the Casita formation Jurassic shale and sandstone layers. Massive Aurora limestones of Cretaceous age which outcrop in the district are anticipated to occur at depth under a thrust fault, and are targets for more pervasive and larger development of skarn mineralization.
The exploration strategy is to follow laterally and downwards the mineralized skarn body which is open in all directions. The quartz porphyry/Jurassic sedimentary host rock contact lies under alluvium cover not more than 100 meters to the south of the new skarn zone and will also be explored in the ongoing drill program.
These initial intercepts indicate over 100 meters of longitudinal length on the new mineralized system, are characterized by both sizable widths and grades which suggests a target for either selected or bulk underground mining methods, and are typical of polymetallic skarn and high temperature carbonate replacement deposits in the Mexican Altiplano. At Cordero, this type of mineralization occurs directly under thin alluvium cover and potential targets could be developed quickly by ramping down from the present surface.
