Prospero Silver Corp.: San Luis Cordero Project Drilling Results with JV Partner Silver Standard Resources

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Mar 3, 2014) - Prospero Silver Corp. (TSX VENTURE:PSL) ("Prospero" or the "Company") is pleased to announce that its JV partner Silver Standard Resources Inc. ("Silver Standard") has completed a 15 hole 5,135 meter diamond drill program at the San Luis Cordero project located in central Durango.

This initial program was aimed at multiple targets including the extension at depth of the Santa Rosa mineralized zone, the extension to the northwest of the Santa Rosa trend, the deep chargeability anomaly under the limestone plateau located in the western zone, the extension to the east of the Santa Rosa East skarn zone, and new targets defined by an IP survey and geochemistry in the eastern La Puerta and India Bonita target zones.

• Widths represent intersected lengths. It is estimated most widths are within 70% of true widths. True widths will be reported at a later date once drill hole cross sections are interpreted.

This drill hole program continues to expand the Santa Rosa vein mineralized zone to the west, and the Santa Rosa East skarn zone to the east, and is open in both directions. In the Santa Rosa East skarn, drill hole SSLC-13-21 intersected mineralization hosted in hornfels, whereas holes SSLC-14-33 and SSLC-14-34 intersected mineralization hosted in calc-silicates. The intersection of hole SSLC-13-21 indicates highly fractured hornfels host-rock tends to represent favorable structural preparation for wider mineralization, whereas calc-silicate hosted mineralization tends to be narrower and higher grade. Other targets that remain to be tested include the Canal Zone and La Puerta skarn.

Under the terms of the Definitive Agreement, Silver Standard has the option to earn a 51% interest within 3 years by incurring total property expenditures of US$3.5M, a minimum of 4,000 meters of drilling in Year 1, and total cash payments of US$1.5M (see Prospero´s News Release of March 20, 2013). Upon Silver Standard earning a 51% interest, the initial joint venture program shall have a minimum program cost of US$4M over 36 months and require the preparation of a pre-feasibility level study on the property. The Definitive Agreement also contains provisions related to additional joint venture exploration and development programs, including the dilution of a joint venture partner´s participating interest if such partner does not fund its portion of a program.

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 by ICP21 (Inductively Induced Plasma-Atomic Emission Spectroscopy) which consists of a 30 gram fire assay with an ICP-AES finish. Silver, lead, zinc and copper values in excess of 100 ppm, 1%, 1%, and 1% respectively were repeated with aqua regia digestion and with ICP-AES (Code OG46).
