Campana National Instrument 43-101 Technical Report Targets Large Mineralized Breccia Complex For Phase 1 Drilling

 Prospero Silver Corp. (TSX-V: PSL) ("Prospero" or the "Company") is pleased to announce that it has received and filed an independent National Instrument 43-101 Technical Report (the "Technical Report") in respect of it's Campana Project located in north central Durango state, 70 km west of Torreon from Peter Christopher, PhD, P.Eng.

The full Technical Report will be posted on SEDAR at and the Company's website at

The Campana project comprises a large cohesive claim position totaling 13,263 hectares. While the project area is covered by alluvium, two outcropping hills have had historic mining. Narrow high grade silver-gold veins were mined from an historic shaft (100 meters deep) located on Tepalcateno Hill. A previous diamond drill program in 2007 encountered multiple intersections of veinlets in both the diatremes and the basement sediments.

The known occurrence outcrops along a small ridge within an alluvium covered valley in a Peñasquito-like (Zacatecas) geological environment. Detailed ground magnetic surveys are in progress and have been used for target definition under alluvium cover in search for the more central (proximal) igneous-associated portion of the system. The zone of stronger alteration/mineralization is associated with magnetic lows. Work to date is centered around a diatreme dike complex 300 meters wide by 600 meters long which is associated with strong argillic alteration (illite-sericite), pyritization. An IP/resistivity survey is being considered to define chargeability anomalies in selected potentially demagnetized target areas. Prospero believes Campana has potential to host bulk-tonnage low-grade precious metal and polymetallic mineralization (Au-Ag-Pb-Zn).

Peter Christopher, PhD, P. Eng is the Qualified Person, in accordance with NI 43-101 of the Canadian Securities Administrators, and is responsible for the technical content of this press release and quality assurance of the exploration data and analytical results.
