VANCOUVER, May 10, 2012 /PRNewswire/ - Wildcat Silver Corporation (TSX: WS) ("Wildcat" or "the Company") is pleased to announce the results for 31 additional drill holes completed on the Company's Hermosa property located in Santa Cruz County, Arizona. Results were mainly targeted at the expansion of the Upper Silver Zone, southeast of the current Hermosa resource. The majority of the drill holes encountering leachable Upper Silver Zone mineralization intersected thicknesses of up to 39.6 metres with average silver grades ranging from 32.6 g/t to 104.4 g/t.
Holes HDS-255, HDS-261, HDS-236 and HDS-256 are located in the patented claim blocks to the southeast of the existing Hermosa resource and all returned significant Upper Silver Zone mineralization.
- HDS-255 intersected high grade Upper Silver Zone mineralization over 30.5 metres beginning at the surface which averaged 104.4 g/t silver.
- HDS-261 extends and leaves open the possible expansion of the Upper Silver Zone onto the unpatented claims to the north and northeast. This drill hole encountered five zones of Upper Silver Zone mineralization ranging in thickness from 4.6 metres to 14.3 metres with silver grades ranging from 34.5 g/t up to 92.8 g/t.
- HDS-236 encountered three zones of Upper Silver Zone mineralization with two zones returning 70.9 g/t silver and 75.7 g/t silver, both over 4.6 metres.
- HDS-256, located in close proximity to HDS-255, intersected an extensive interval of Upper Silver Zone mineralization from the surface down 39.6 metres, averaging 49.2 g/t silver.
Hole HDS-240, located in the northern portion of the existing resource, intersected six mineralized intercepts of the Manto Oxide Zone with the best intercept returning 148.9 g/t silver and 11.32% manganese over 16.8 metres. The bottom portion of the drill hole contained four mineralized intersections of Sulfide Skarn Zone, extending mineralization from the previously announced hole HDS-104. These mineralized intercepts contained significant silver, lead, zinc and manganese with one of the best intercepts returning 7.6 metres of 122.7 g/t silver, 8.03% manganese, 6.98% zinc, 5.15% lead and 0.42% copper.
Hole HDS-265, located in the northeast of the Hermosa patented claim block, expands the Upper Silver Zone and the Manto Oxide Zone to the east of the main portion of the Hermosa resource. This hole intersected four zones of Upper Silver Zone mineralization and two zones of Manto Oxide Zone mineralization. The best Upper Silver Zone intercept was 4.9 metres over 91.1 g/t silver and the best Manto Oxide Zone intercept was 21.5 metres of 65.8 g/t silver, 10.56% manganese and 3.68% lead.
The Company's most recent drill program was completed in March 2012, having drilled 212 holes for a total of approximately 55,700 metres. A total of 54% of the drill and assay values were included in the February 2012 mineral resource estimate for the Hermosa project. Wildcat expects to provide a further update to the current mineral resource to incorporate all of the drilling in the third quarter of this year. Following this announcement there are 57 drill holes with assays and analysis still in process, which are expected to be released by the end of this quarter.
The Company is also making significant progress on its metallurgical optimization studies and intends to complete pilot plant work mid-year. As a result, the Company intends to deliver a preliminary economic assessment in the third quarter of this year, which will include the new mineral resource as well as updated metallurgical testwork.
A summary of the drill results is provided below. Please also see attached map.

A complete list of all drill intercepts, location map and 3D model of the Hermosa mineralization are available on the company's website at www.wildcatsilver.com.
The results of Wildcat's drilling results have been reviewed, verified and compiled by Don Taylor, MSc., PG, President and Chief Operating Officer for Wildcat Silver, a qualified person as defined by National Instrument 43-101 (NI 43-101). Mr. Taylor has more than 25 years of mineral exploration and mining experience, and is a Registered Professional Geologist through the SME. Mr. Taylor is also a Licensed Professional Geologist in several US states.
Assays and Quality Assurance/Quality Control
To ensure reliable sample results, Wildcat has a rigorous QA/QC program in place that monitors the chain-of-custody of samples and includes the insertion of blanks, duplicates, and certified reference standards in each batch of samples. Core is photographed and split in half with one-half retained in a secured facility for verification purposes. Sample preparation (crushing and pulverizing) is performed at Skyline Laboratories, an ISO/IEC accredited lab located in Tucson, Arizona. Skyline Laboratories prepares two pulps of all samples and completes analysis of one pulp sample by ICP for Cu% (copper), Pb% (lead), Zn% (zinc) and Mn% (manganese). The second pulp is shipped to Inspectorate Labs, an ISO: 9001-2008 accredited laboratory in Reno, Nevada, where the duplicate pulp is analyzed for Au (gold) and Ag (silver). Silver values are determined by gravimetric fire assay (1 AT) with gold values determined by an AA finish from the same dore bead: Final silver value is the weight of the dore bead minus the AA gold value. In certain drill holes Skyline completes analyses of pulps for gold (FA-1AT/AA) and silver is determined by multi-acid digestion/AA finish. If the silver value is greater than 150 gpt the sample is redone by gravimetric FA (1AT) with the gravimetric gold value subtracted. At both labs if the FA/AA Au value is greater than 3 gpt the Au assay is repeated by FA gravimetric methods. Certain duplicate pulps have gold-silver QA/QC checks run at Skyline by the above methods. Also certain duplicate pulps also have Cu, Pb, Zn, Mn QA/QC checks a using ICP/AA methods and 30 element spectral ICP determined at Inspectorate after 4-acid digestion.
Wildcat is a Canadian mineral exploration company focused on development of Hermosa, its 80% owned silver project located in Santa Cruz County, Arizona. The project currently has an indicated mineral resource of 101.4 million tonnes averaging 53.18 grams per tonne silver for a total of 171.3 million ounces of silver in addition to an inferred mineral resource of 83.6 million tonnes averaging 36.42 grams per tonne silver for a total of 98.6 million ounces of silver as announced in the February 6, 2012 press release.

About Reserves and Resources
This press release uses the terms indicated and inferred resources as a relative measure of the level of confidence in the resource estimate. Readers are cautioned that: (a) mineral resources are not economic mineral reserves; (b) the economic viability of resources that are not mineral reserves has not been demonstrated; and (c) it should not be assumed that further work on the stated resources will lead to mineral reserves that can be mined economically. In addition, inferred resources are considered too geologically speculative to have any economic considerations applied to them. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for certain preliminary economic assessments. Readers should also refer to the Company's Annual Information Form for the period ended December 31, 2011 and other continuous disclosure documents available at www.sedar.com, which is subject to the qualifications and notes set forth therein.
