Prospero Drills 3.12 Meters of 13 G/T Au, 24.5 G/T Ag at the Baborigame Project, Chihuahua

Vancouver, B.C., - Prospero Silver Corp (TSXV: PSL) (the "Company") is pleased to report the results of Phase 1 drilling at its Baborigame project in southwestern Chihuahua state, Mexico. The project area has a total of 9 vein systems some of which had historic mining. In this first drilling program, 4 of the veins were drilled. Highlights include diamond drill hole PBAB-10-11 with 13 g/t Au and 24.5 g/t Ag over a core length of 3.12 meters; diamond drill hole PBAB-10-09 with 6.1 g/t Au and 75.2 g/t Ag over a core length of 1.4 meters, and diamond drill hole PBAB-10-08 with 2.3 g/t Au and 11 g/t Ag over a core length of 1.58 mts. All three intersections were under the historic Los Angeles mine (see figure at bottom of this News Release). Three other vein systems were drilled in the district including the Diente de Oso vein; the Encerredora North vein and the Cebollas vein (one drill hole). The following table exhibits the results of all the drill holes:

The drill holes on the Los Angeles vein indicate increasing grades and widths of mineralization towards the west, the area believed to represent the feeder zone of the vein as discussed in the website disclosure of the Company for the Baborigame property. A revised longitudinal section of the Los Angeles vein is shown at the end of this news release. The new drill hole data starts verification of the historical gold assays and vein widths shown in the section.

In plan view the intersections are located further west and at the approximate elevation of the western end of level 5. The vein changes strike from east-west to a WNW orientation which may reflect a more dilational trend hosting wider vein material as observed in the increase in both grade and width in hole PBAB-10-11.

The drill holes in Diente de Oso, Encerradora North and Cebollas veins intersected structures hosting robust veins with low grades. A high grade stringer was encountered in the footwall of drill hole PBAB-10-01.

Most of the mineralization in the Baborigame district tops out close to elevation 2100 meters above sea level. The Cebollas vein dips 75° to the north which was shallower than anticipated and the drill hole intersected the vein with anomalous values at elevation 2100 meters. Deeper drilling is required to reach to test the better mineralized zone of the district.

The Company is encouraged by the results from this initial phase of drilling. A follow on drill program will target:

(a) additional holes along the western extension of Los Angeles vein where the presence of high grade hypogene gold mineralization has been identified,
(b) deeper drilling on the Cebollas vein, and
(c) drilling under old stopes of the Dolores, Encerradora, Encerradora South and Encerradora Central veins systems.
