Prospero Provides Drilling Update for El Petate Project

Vancouver, British Columbia--(Newsfile Corp. - January 10, 2018) - Prospero Silver Corp. (TSXV: PSL) ("The Company" or "Prospero") is pleased to provide a final update on the first-stage reconnaissance drilling of its Petate project in Hidalgo state, Mexico. Twelve shallow holes were completed primarily to establish structure and to allow for more accurate targeting of deeper mineralized zones. The first 5 holes were reported in November 2017 (see news release dated November 18, 2017). The drilling at Petate is being carried out as part of its reconnaissance drilling campaign of 3 targets financed by strategic partner Fortuna Silver Mines Inc.

Tawn Albinson, the President of Prospero Silver commented: "Petate is the second project of three selected for first-pass drilling as agreed with our strategic partner Fortuna Silver. Under our arrangement with Fortuna, when we have completed drilling three projects, they have the right to select one for a joint venture. We are happy with the results at El Petate. In particular, holes 1, 9 and 11 have highlighted interesting grades over intervals of up to 24.9m downhole, although with unknown strike extent, indicating prospective deeper targets for a follow-up program. We are strongly aligned with Fortuna to drill as many of Prospero's projects as possible, hence the plan to mobilise onto the next target, Pachuca SE, as soon as possible — hopefully in January. The Pachuca SE target lies about 20km southeast of the Vizcaina vein, one of the largest silver-rich epithermal veins in the world."

Cross sections for all holes, and a table of drill collar locations, dips and azimuths are available on Prospero's website here: http://www.prosperosilver.com/s/ElPetate.asp. Assay results have now been received for the remaining 7 holes (PET-17-06 to 17-12). Drill highlights include:

*Drill intercepts have been rounded to the nearest 5cm throughout this release.

El-Tajo Zone

Hole PET-17-06

Hole PET-17-06 drilled into the El Tajo target beneath and parallel to hole 17-05 with an azimuth of 325. (Hole 17-05 returned a best interval of 18.5m@ 0.8g/t Au + 5.0 g/t Ag with poor recoveries) Hole 17-06 was stopped at 165.6m and cut multiple mineralized zones including:

NB: The true width of the mineralized intercepts is uncertain.

From surface to 14.7m the hole cut alluvium with clasts of jasperoid and andesites. The gold-bearing intervals from 44m to 54m and from 60.3m to 63.5m are hosted in fragmented black jasperoid after limestone, and correspond to the 18.5m @ 0.8g/t Au reported for hole PET-17-05. From 63.5m to the end of hole, 17-06 cut fresh dolomitized limestones.

Hole PET-17-06 also hosts several intercepts with elevated Ag, Pb, and Zn values including;

• 0.2 m of 30 g/t Ag, 2% Pb, 4.7% Zn from 26.6m downhole;

• 1.5m of 0.43 g/t Au, 117 g/t Ag from 51.15m; and

• 0.25m of 1.21 g/t Au, 271 g/t Ag, 0.12% Pb, and 0.13% Zn from 62.55m downhole.

This suggests that the Tajo target area has potential at depth to zone into precious metal-enhanced base metal mineralization.

Hole PET-17-07

Holes 17-07 and -08 were drilled from the same collar position as hole 17-06, but on a section line oriented roughly northeast-southwest. (Hole 17-07 azimuth roughly SW, 17-08 azimuth to the northeast). The hole cut reddish muddy alluvium with local jasper fragments from surface to 31.6m. From 31.6m to the end of hole at 93.2m it cut limestone with a jasperoidal zone from 48.9m to 54.4m. Interestingly it returned anomalous gold mineralization for much of its length as follows:

NB: The true width of the mineralized intercepts is uncertain.

Hole PET-17-08

Hole 17-08 was drilled from the same collar position as hole 17-07. It ended at 165.2m in fresh limestone. The hole returned 2 anomalous gold intersections with a best of 11.8m @ 0.15g/t Au from 13.3m downhole hosted by a zone of jasperoidal breccia with silica-calcite veining. A second jasoperoid from 53.8m downhole returned 7.3m @ 0.14g/t Au + 11.5g/t Ag. Both zones appear to be steeply dipping and possibly correlate with surface outcrops of jasperoid.

Apartadero SE Target

Hole PET-17-09

Hole 17-09 was drilled across the trace of hole PET-10-01 roughly from north to south to investigate the intersection of 3.4m @ 3.5g/t Au noted from 81.9 to 85.3m in hole PET-17-01 (see news release dated November 8, 2017). The hole cut multiple gold-bearing zones as follows:

NB: The true width of the mineralized intercepts is uncertain. * Recoveries between 6.5m to 31m were poor — approximately 20% recovery of sand, jasperoid fragments and marble.

The intercept from 43.8m appears to be the zone seen in hole 17-01 albeit deeper in the section, suggesting a steep dip to the zone. The highest grade in hole 17-09 was from a 40cm sample which returned 3.5g/t Au from 43.8m downhole. The zone has now been traced for 50m vertitcally below where hole 17-01 cut it.

Hole PET-17-011

Hole 17-11 was drilled from a collar roughly 150m south of 17-09 with an azimuth approximately due north again investigate the intersection of 3.4m @ 3.5g/t Au noted in hole PET-17-01. The hole appears to have cut the same zone from roughly 26.7m to 42.7m downhole, returning 16m @ 0.75 g/t Au and 2g/t Ag (see cross section).

Hole PET-17-012

Hole 17-12 was the last hole drilled in the current program at Petate from a collar roughly 50m south of hole 17-11, with an azimuth north-northeast to test beneath the intercept reported above for hole 17-11. The hole was stopped at 216.2m in limestone after cutting 3 jasperoid zones. Prospero's geologists believe the zone in hole 11 was cut between 66m to 69.9m downhole implying its dip has flattened. This zone returned 3.9m @ 1.2 g/t Au + 3.7 g/t Ag. A second zone from 176.5m downhole returned 4.4m @ 13.6 g/t Ag with trace anomalous gold.

Future Drilling

Prospero and its strategic investor Fortuna Silver Mines Inc are systematically drill testing a number of targets in Prospero's portfolio. Following the completion in December 2017 of the planned 12 holes at El Petate, Prospero is now planning to drill its Pachuca SE target, 20-25km southeast of the historic silver mining city of Pachuca. A 3-4-hole, ±1,800m program is scheduled to begin as soon as the final drill permits have been received.
