Wildcat announces substantial resource increase at Hermosa - Includes new silver-only zone

VANCOUVER, Feb. 6, 2012 /PRNewswire/ - Wildcat Silver Corporation (TSX: WS) ("Wildcat" or "the Company") is pleased to announce an updated mineral resource estimate for its Hermosa project, located in Santa Cruz, Arizona.  The updated mineral resource is comprised of:

  • Indicated resource of 101.4 million tonnes of 53.18 g/t silver for 171.3 million ounces of silver.
  • Inferred resource of 83.6 million tonnes of 36.42 g/t silver for 98.6 million ounces of silver.

This represents a significant increase compared to the previous 2010 mineral resource estimate. The Company has also identified and included in the revised resource a new silver-only zone which is amenable to standard cyanidation and Merrill Crowe recovery.

"We have been successful in increasing the total silver resource today by more than two times when compared to the previous 2010 resource at Hermosa, and by five times when compared to the initial resource in 2007," said Chris Jones, Wildcat's President and CEO. "Further, through definition drilling we have significantly upgraded the quality of the resource. The new resource reflects a full 64% of the contained silver ounces in the indicated category, which is more than double the portion contained in the 2010 resource.  While achieving this increase, our discovery cost per ounce of silver added in the 2012 resource was minimal at C$0.056 per ounce."

New Upper Silver Zone

The new silver-only zone ("Upper Silver Zone") lies above and adjacent to the Manto Zone in the overlying volcanic rocks.  The new zone has been included in the resource as a result of recent metallurgical testing that indicates that it is amenable to standard cyanidation and Merrill Crowe recovery. The previously disclosed drill results for this zone reported silver grades ranging from 3.5 grams per tonne up to 175 grams per tonne. Preliminary metallurgical testing indicates that recoveries for this material are expected to be in the 40 - 45% range with low cost, direct cyanidation. This new leachable Upper Silver Zone has the potential to positively impact the project because this material was previously considered waste.  This zone remains open to the north, east and south for further expansion.

Updated Mineral Resource Estimate

Wildcat's updated mineral resource for its Hermosa project is comprised of 171.3 million ounces of silver in the indicated category and 98.6 million ounces in the inferred category.  A summary of the mineral resource is provided in the table below.  It should be noted that mineral resources that are not mineral reserves do not have demonstrated economic viability.

    1. The mineral resource is tabulated on a recovered value per tonne calculation including metal price and recovery of Ag, Mn, Zn and Cu based on the following inputs.

            Metal   Price   Recovery
            Silver   $25.76/oz   90%
            Manganese  $0.60/lb  95%
            Zinc   $0.93/lb   80%
            Copper   $3.21/lb   90%
                 
      The Manto and Upper Silver Zone resources are within an open pit cone geometry based on a $27.55/tonne process plus G&A cost and $1.65/tonne mining cost and the Manto resource is tabulated at a $27.55 per tonne recovered value cut-off grade.

The Upper Silver Zone resource is within the open pit cone geometry and is tabulated using a $7.12 per tonne recovered value cut-off grade.

The Skarn Zone resource is located below the open pit cone geometry and is tabulated using a $60.60 per tonne recovered value cut-off grade.
       

To-date the Company has completed approximately 49,045 metres of a planned 51,850 metre drill program.  This 2012 mineral resource estimate includes drill and assay data up to mid-September 2011, which accounts for only 54% of the planned drill program. Exploration on the Hermosa property continues with four drill rigs (two core, 2 RC) operating on site.  Wildcat expects to provide a further update to the current mineral resource in order to incorporate all of the drilling later this year. The Company is on track to deliver an updated Preliminary Economic Assessment based on the current resource announced today in the first quarter of 2012 and expects to provide a further update based on the current drilling results later in 2012.

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 year ended June 30, 2011 and other continuous disclosure documents available at www.sedar.com, which is subject to the qualifications and notes set forth therein.
