Wildcat further increases Hermosa mineral resource
TORONTO, Aug. 9, 2012 /PRNewswire/ - Wildcat Silver Corporation (TSX: WS) ("Wildcat" or "the Company") is pleased to announce a further increase to the total mineral resource for its Hermosa project located in Santa Cruz, Arizona. The Company has also upgraded a significant portion of its indicated resource into the measured category. The updated mineral resource estimate includes:
- Measured and Indicated resource of 194 million tonnes of 37.7 g/t silver for 236 million oz of silver
- Inferred resource of 80 million tonnes of 30.9 g/t silver for 79 million ounces of silver
"The drill program completed earlier this year has resulted in the global Hermosa mineral resource increasing once again and is now approximately 2.5 times larger than the previous 2010 resource used in the prior preliminary economic assessment," commented Don Taylor, Wildcat's President and Chief Operating Officer. "We are also pleased that we were able to upgrade a significant portion of the resource into the measured category, which comprises more than 40% of the total resource. We are currently focused on incorporating this resource into a revised preliminary economic assessment which we plan to complete by the end of this quarter."
This mineral resource estimate is effective as of August 9, 2012 and includes drill and assay data up to March 2012 which contains all 212 holes (55,700 metres) completed in the most recent 2011/2012 drill program. A summary of the total resource is provided below and is reported on a 100% basis.
It should be noted that mineral resources are not mineral reserves and do not have demonstrated economic viability.

* The mineral resource is constrained within a Whittle optimized pit shell based on the following metal prices and recoveries:
Metal | Price | Recovery |
Silver | $25.76/oz | 90% |
Gold | $1,300/oz | 85% |
Manganese | $0.60/lb | 95% |
Zinc | $0.93/lb | 80% |
Copper | $3.21/lb | 90% |
The mineral resource is based on processing costs of US$27.55/tonne for the Manto Zone. The Upper Silver Zone mineral resource is tabulated using a silver cut-off grade of 8.57 g/t.
Previous mineral resources did not include a resource for gold as no metallurgical test work had been completed to prove its recovery or economic viability. As a result of recent test work the expected recovery included in the above table has been used and gold has been included in the total mineral resource.
In addition to the above mineral resource, Hermosa also has a deep Skarn Sulfide Zone which hosts 3.8 million tonnes of 30.84 g/t silver, 4.68% manganese, 0.07% copper and 2.31% zinc for total contained silver ounces of approximately 4.0 million. This Skarn resource was previously announced in the Company's February 6, 2012 mineral resource press release and included in the NI 43-101 Hermosa Technical Report dated March 21, 2012. The Skarn resource was not affected by the current drilling and therefore was not listed in the updated resource totals as it was not reviewed by Scott E. Wilson Consulting, Inc.
The Company has also completed metallurgical test work including pilot plant studies on both the Manto Oxide and Upper Silver Zone ore at Hazen Research Inc. in Golden, Colorado. Results are expected to be announced later in the quarter once results of the test work have been received and analysed. Wildcat is on track to deliver an updated Preliminary Economic Assessment which will include the new mineral resource announced today and the results from the metallurgical test work by the end of the third quarter of 2012.

About Mineral Reserves and Mineral 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.
