Prospero begins drilling at Buenavista silver-gold project in Mexico

Prospero Silver Corp (TSXV: PSL) (the "Company" or "Prospero") is pleased to announce that drilling started at the Buenavista project in northwest Durango State, Mexico on May 26, 2018.

This is the fourth project to be drilled under the terms of a second round of strategic investment from Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) made in May 2018, as per the revised agreement and warrant exercise announced on May 7, 2018. As on the first three projects, the drill program is preliminary in nature and intended to confirm below surface structures and allow the Company to determine where in the vertical epithermal column an ore zone might lie.

The 3,000 meter core drill program, starting on Buensavista South Stockwork, will test at least 4 principal drill-ready zones. In addition to the Buenavista South Stockwork, other targets include the Buenavista NE dike/vein, the Camaleon vein and the Pajaro Stockwork. The surface expression of these targets occurs within the lower portion of a strong high-level argillic cap. The exploration program contemplates drilling down to a deeper more favorable geologic level to further investigate the grade potential of a possible preserved epithermal mineralized zone. Information on the Buenavista project can be found on Prospero's website at:

Prospero's field crews have just completed channel sampling at the Pajaro zone and a structural consulting geologist is currently on site to conduct detailed structural mapping and assist in drill hole targetting.

Buenavista is a precious metal-bearing, structurally controlled vein systems centered on a rhyolite dome complex in in NW Durango, 270km northwest of Durango City. Fresnillo's recently commissioned San Julian Mine lies 20 Km to the northwest. . . Alteration at surface is high-level argillic suggestive of the presence of an epithermal deposit at depth, possibly hosted in Lower Volcanic Series andesites.

Between 1996 and 2008, eleven drill holes were completed at the Buenavista NE zone testing for relatively shallow mineralization. The best historic intersections include:

  • 2.37m of 400g/t Ag and 0.27g/t Au 100m in hole 96-1.
  • 4.3m of 87g/t Ag and 0.08g/t Au in hole BE-04 including 245g/t Ag over 1.5m.
  • 9.3m of 125g/t Ag and 0.35g/t Au in hole BE-05 including 276g/t Ag over 1.15m.
  • 8.0m of 129g/t Ag and 0.07g/t Au in hole BE-06 including 206g/t Ag over 4.5m.

Note that these results are historic in nature. Prospero has not yet completed the work required to verify them and as such they cannot be relied upon. However, the drilling and assay work was believed to have been carried out to a high standard.
