Wildcat drilling increases Manto Zone thickness in centre of proposed pit
VANCOUVER, Jan. 10, 2013 /PRNewswire/ - Wildcat Silver Corporation (TSX: WS) ("Wildcat" or "the Company") is pleased to announce the results for six drill holes completed on the Company's Hermosa property located in Santa Cruz County, Arizona. These reverse circulation drill holes, located in the centre of the proposed open pit, were undertaken to validate certain historic results and upgrade the mineral resource estimate. They were also designed to test the depth of the resource in areas of historic shallow rotary-hole infill drilling and provide representative material for additional metallurgical testing.
The new drilling confirmed the results from the historic drilling. In addition, drill hole HDS-329 increased the thickness of the higher grade Manto Oxide Zone mineralization by approximately 23 metres beyond what was tested by previously drilled hole HDS-15. Significant intercepts include HDS-324 returning 44.2 metres of 219.8 g/t silver and 5.09% manganese, HDS-326 returning 13.7 metres of 338.1 g/t silver and 9.91% manganese and HDS-327 returning 64.0 metres of 151.6 g/t silver.
Wildcat plans to incorporate these drill results into a revised mineral resource and mine plan to be included in the Hermosa prefeasibility study, which is being led by M3 Engineering and Technology Corporation of Tucson, Arizona. The prefeasibility study is scheduled for completion in the second quarter of 2013. Further as a result of the current drilling, approximately five tonnes of Manto Oxide Zone and ten tonnes of Upper Silver Zone material were collected for additional prefeasibility metallurgical testwork, which is primarily focused on optimizing silver and by-product recoveries. Testwork is currently underway and being conducted by Hazen Research, Inc. in Golden, Colorado.
A summary of the drill results is provided below. Please also see the map at the end of this press release for drill hole locations.

Qualified Person
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. Further, certain duplicate pulps also have Cu, Pb, Zn, Mn QA/QC checks using ICP/AA methods and 30 element spectral ICP determined at Inspectorate after 4-acid digestion.

About Reserves and Resources
This press release uses the terms measured, 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.
