Prospero Silver Announces Initial San Luis Cordero Resource Estimate

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct 7, 2014) - Prospero Silver Corp. (TSX VENTURE:PSL) ("Prospero" or the "Company") is pleased to announce the initial NI-43-101 compliant resource estimate for the Santa Rosa vein and the Santa Rosa East skarn of its San Luis del Cordero property located in central Durango, Mexico. A total of 6,127 meters of diamond drill holes were incorporated into a database to calculate a resource along a 1,200 meter E-W segment of the Skarn Rim Zone (see Figure 1).

Highlights include:

• The table below shows the estimated indicated and inferred resources for both mineralized zones as of October 1^st, 2014. Resources were calculated using Inverse Distance cubed (ID³).
• Resources are reported at a silver-equivalent cut-off grade of 85 g/t. Metal prices: silver=$19/oz, copper= $3.00/lb, zinc=$0.90/lb.
• The known mineralization is open in several directions and the property has potential for new mineralized zones, which require additional drilling, such as the Canal and La Puerta targets.

Figure 2 exhibits the distribution of AgEq grade in the two mineralized zones.

Note: The Sta. Rosa East skarn zone in its western extension overlaps slightly the Sta. Rosa vein so the zones are shown separately in Figure 2.

The Company considers the project´s immediate potential to add ounces of silver will be in the extensions of the known mineralized zones, namely A), west of the Santa Rosa vein, B), additional skarn lenses in the HW of the vein, and C) the eastern extension of the Sta. Rosa East skarn zone. The 2.5 km stretch of the NE striking eastern segment of the Skarn Rim Zone will also be a high priority drilling target. Having completed the initial resource, follow up programs will include drilling to upgrade and expand the existing Indicated and Inferred Resources, and initial metallurgical testwork. The Company also sees the need to review overall priorities for the property including focusing exploration and development efforts on the high grade vein resource.
Geology

The Sta. Rosa vein intersections vary in width from 2.10 meters to 2.62 meters and have an average true width of 1.99 meters with well-defined walls. The Sta. Rosa East skarn intersections vary in width from 2.19 meters to 30.59 meters with an average true width of 9.0 meters, with grade rather than structure generally defining the limits of mineralization.

3D modeling of the Sta. Rosa vein indicates the vein may be steeper than anticipated and that historic holes SL-00-2 and SL-00-3 were shut down before reaching the vein, suggesting the vein may continue at depth under hole SL-00-1. Additionally, holes SL-00-1, SL-00-2 and SL-00-3 intersected several mineralized skarn lenses up to 140 meters in the HW of the Sta. Rosa vein. These lenses may represent the upper parts of another mineralized skarn at greater depth and require deeper drilling to test this possibility.

The Sta. Rosa vein is open to the west and appears to be related to the shallow intersection of drill hole SSLC-13-24 (11.08 to 12.10 meters, 1.02 meters with 115 g/t silver, 0.14% copper, 0.98% zinc), located 450 meters further west, if the vein changes to a more westerly strike along its western extension (Figures 1, 2). The intersection of SSLC-13-24 is slightly below the contact with the Aurora limestones, in a position where the Sta. Rosa ore shoot is known to be lower grade (Figure 2).

The Sta. Rosa East skarn is open both to the east and at depth. There are insufficient holes at depth (PSLC-11-18, PSLC-11-12, SSLC-14-32 and SSLC-13-22) to establish clearly the degree of continuity of mineralization along its extension at depth. There is a 500 meter gap between holes PSLC-11-18 and SSLC-14-32 where a feeder zone could be present which requires additional drilling. A hanging wall skarn zone located at the eastern end of the main skarn zone has been traced by drill holes. This structure remains open along strike and down dip and requires additional drilling to confirm continuity and to define its extent.

Subsequent to the last drill program in 2014 and additional mapping, the Skarn Rim Zone is shown to envelope the intrusive complex in a "V" shape as shown in Figure 1. The initial focus has been on the 1,200 meter stretch between the Santa Rosa vein and the Sta. Rosa East skarn. Further attention and drilling will focus along the 2500 meter long NE striking eastern shoulder of the intrusive complex. This includes, at the northeast end, the La Puerta skarn, which outcrops as a continuous 800 meter length and remains unexplored. Hole SSLC-13-30 was stopped before reaching the La Puerta skarn indicating it is steeper than anticipated, and will require drilling pads closer to the outcrop to explore the skarn at depth. To the southwest, hole PSLC-17 was drilled in the Canal Target zone, had an intersection which showed elevated zinc values (4.14 meters with 96 g/t silver, 0.38% copper and 11.9% zinc), and is open in all directions.

"We are very pleased to get this initial resource estimate published. Having worked on SLC and neighboring projects for over 10 years we see considerable exploration potential in the district" said Tawn Albinson, President and CEO of the Company. "We see two types of mineralization, a high grade vein component that could potentially support an initial startup operation, as well as a higher tonnage lower grade skarn type component that could sustain a longer term operation. Our internal mission as a next step, is to expand the existing resources by focusing on high priority drill targets."

A quality control program is adopted to ensure best practices in the sampling and analysis of drill core. Samples are shipped in sealed bags to ALS-Chemex Laboratory preparation facilities in Chihuahua City (ISO 9001). Shipments include intermittent standards and blanks. Sample pulps are shipped to ALS-Chemex Laboratories in North Vancouver, B.C. for analysis. All samples were assayed by multielemental ME-ICP41, and gold by ICP21 (Inductively Induced Plasma-Atomic Emission Spectroscopy) which consists of a 30 gram fire assay with an ICP-AES finish. Silver, lead, zinc and copper values in excess of 100 ppm, 1%, 1%, and 1% respectively were repeated with aqua regia digestion and with ICP-AES (Code OG46). T. Hodson, P.
