Prospero Silver Corp. Provides Drill Update

Prospero has selected a drill contractor for its planned 6,000m program on three projects. Drilling is scheduled to begin in late June. Prospero will first drill 4 holes at its Matorral project in the Santa Maria del Oro camp. The plan is then to drill 8 holes at its Petate project followed by 8 holes at Pachuca SE - project descriptions below. This drilling program is under the terms of Prospero's strategic agreement with Fortuna Silver Mines. Drill collar maps for Matorral will be available shortly on Prospero's website.

Project Portfolio

Santa Maria del Oro Project, Durango State

Matorral and Lineament targets

Matorral has over 7km of prospective structures and is one of two targets on the 9,066 hectare Santa Maria del Oro claims. A drill permit has been received by Prospero for 20 drill pads in 3 different areas to test for down-dip precious metal mineralization. Prospero's sampling has returned silver values from trace up to 460g/t Ag at surface.

The second target, the Magistral Lineament on the western side of the district, is approximately 1.8km away from the historic Santa Maria del Oro mine. The Lineament structure was defined by geophysics (see news release dated November 23, 2011). Surface access permits have been obtained and drill permits were received on April 26^th, 2017.

Petate, Hidalgo State 

The 6,868 hectare Petate property is the most advanced of Prospero's projects, with drill permits in progress for 30 drill sites and surface access already secured from the land owners. High-level epithermal alteration is exposed over a 5x4 km area with highly anomalous gold and silver hosted in extensive outcrops and float of steep to strata-bound jasperoid. The significant size of the silicified zones indicates that Petate is a robust mineralized system with excellent potential to host a replacement type deposit at depth. 

Pachuca Southeast, Hidalgo State

The Pachuca SE target consists of high-level epithermal-style alteration exposed in clay pits adjacent and on-strike from the historic Pachuca mining district. Prospero received approvals from the Mexican archaeological agency (INAH) paving the way for obtaining title on the 7,256 hectare claim.

The anomalous geochemistry and clay alteration at Pachuca SE target are very similar to that seen in the Vizcaina structure above the historic Pachuca Mine. The target has size potential, strong hydrothermal alteration and a number of geochemical anomalies have been identified associated with structures that could host a preserved Pachuca-type epithermal deposit at depth. 

Bermudez, Chihuahua

The 430 hectare Bermudez project is in Chihuahua, about 150km west of the City of Chihuahua. Additional mapping and sampling has been completed on the 2.5km strike length of the high-level low-sulfidation vein system. Based on assay results of 51 new samples, the best locations for 4 drill sites have been selected to test the potential for deeper mineralization.

Acquisition of New Projects

Prospero's geologists have completed a 4 month field program. Selection of new projects will be done in collaboration with Fortuna Silver at the upcoming joint technical committee meeting.
