Vancouver, British Columbia--(Newsfile Corp. - November 8, 2017) - Prospero Silver Corp. (TSXV: PSL) ("The Company" or "Prospero") is providing a preliminary update on the first-stage reconnaissance drilling of its Petate project in Hidalgo state, Mexico. Eight shallow holes have been completed to date primarily to establish structure and to allow for more accurate targeting of deeper mineralized zones. The initial holes are in the Apartadero zone which had the highest gold and silver anomalies at surface hosted in extensive outcrops and float of steep to stratabound jasperoid (see Prospero news release dated June 25th, 2014).
Assay results have been received for 5 holes to date. Drill highlights include:
Tawn Albinson, the President of Prospero Silver commented: "We were very pleased to encounter gold grades in some of the early shallow reconnaissance holes. The drill plan developed with Fortuna was designed to get a handle on structural controls on the highest priority targets before deeper drilling. We now see a strong correlation between the presence of black jasperoids after limestone and grade. A few more shallow holes will be required over the next two weeks to get a decent picture of the strike and dip of what we think are the controlling structures."
Hole PET-17-05 returned highly encouraging gold grades over 3 separate intervals (18.3m, 12.2m and 18.5m intervals respectively), with grades increasing downhole, and a best intercept of 0.80g/t gold over 18.5 metres from 48.6m downhole, albeit with poor core recoveries. Hole PET-17-06 is a re-drill of hole #5 using PQ diameter core at a slightly steeper dip of 55º. Hole PET-17-01 tested the Apartadero SE target. Holes 02, 03 and 04 tested the Apartadero Central target. Hole 05 and 06 tested the El Tajo target. 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.
Drilled on section line G-G´ to test beneath extensive outcrops of jasperoids at the El Tajo zone, PET-17-05 is mineralized over most of its 67m length. Highly encouraging gold grades were cut over 3 separate intervals (18.3m, 12.2m and 18.5m intervals respectively), with grades increasing downhole. Difficult drilling conditions with broken jasperoidal ground and poor recoveries forced the abandonment of the hole at a final depth of 67.1m. The highest grades are associated with intervals of black jasperoidal breccias; for example from 63.35m to 64.05m which assayed 3.66g/t Au + 14.5 g/t Ag. Hole PET-17-06 was subsequently drilled from the same collar location with the same azimuth but at a dip of 55 degrees as a redrill of 05. Assays are pending for hole PET-17-06. Key weighted average intervals from hole 05 are:
PET-17-01 was stopped at 178.9m. Gold-mineralized jasperoid zone was intersected over a 3.4m interval from 81.85m to 85.25m which returned 3.5g/t Au, although core recoveries at (32%) were low due to the presence of voids, not bad ground. The jasperoid is similar to a zone mapped at surface which may be its upward projection. From 124.5m to 151.8m (27.3m) the hole intersected calcite-veined, brecciated, and variably decalcified limestone. One sample returned a weak gold anomaly (0.18ppm) in this zone.
It now appears that the hole was drilled in the hanging wall or footwall of a jaseroidal structure and parallel to it rather than perpendicular to its strike. Prospero and Fortuna are considering drilling a second short hole at the Apartadero SE target from north to south in order to test for the presence of an east-west structural control for the Apartadero SE jasperoids.
Apartadero Central Target
Hole PET-17-02
PET-17-02 was drilled due north under the Apartadero Central target to test for its down dip extension. The best candidate to represent the Apartadero Central zone is a brecciated interval from 22.40 to 30.35 meters which hosts grey silicified limestone fragments supported in a soft orange reddish matrix. Only one sample (W680086) returned weakly anomalous gold (0.13 ppm Au over 1.5m).
Hole PET-17-03
PET-17-03, which was stopped at 63.5m depth, was drilled along the same section as PET-17-02 but from north to south and returned no significant results. The purpose of this hole was to clarify if all the brecciated zones of PET-17-01 are related to manto-like sub-horizontal zones or are related to steeper northwest-southeast striking structures. The hole cut fresh limestone with calcite veinlets and stockworks, and no brecciation suggesting the later case is more likely. It is considered likely that hole PET-17-03 was drilled entirely in the footwall of the Apartadero Central occurrence.
Hole PET-17-04
Hole 04, drilled to a final depth of 113m, was collared to test the Apartadero Central target from east to west. The hole cut fossiliferous limestones with local calcite veining, and is also suspected to have drilled the footwall of the Apartadero Central target. No significant assays were received.
Future Drilling at El Petate
An additional 5-6 holes are planned for El Petate in the current round of drilling. The Company hopes to complete this before Christmas. After El Petate, in the New Year Prospero and Fortuna are planning to drill the Pachuca SE and Bermudez projects.
