TORONTO, ONTARIO--(Marketwire - Sept. 20, 2012) - Silver Bear Resources Inc. ("Silver Bear" or the "Company") (News - Market indicators) is pleased to announce that it has received a National Instrument 43-101 ("NI 43-101") compliant Inferred mineral resource estimate on its Nizhny Endybal prospect area. It is located roughly three kilometers from the current NI 43-101 resource area at Vertikalny on the Mangazeisky property (see figure 1). Silver Bear has delineated a new and additional Inferred resource of 13.5 million ounces of Silver at a grade of 133g/t Ag there. Now, the Company's total NI 43-101 compliant resources on its Mangazeisky property are 1.1 million tonnes containing 17.9 million ounces silver at 518 Ag/t of Indicated mineralization and 4.3 million tonnes containing 43.5 million ounces silver at 282 g/t Ag of Inferred mineralization (see table 2). This represents a 44% increase in Inferred resources over previous resource statements (see September 28, 2011 press release).

Table 1 highlights the details of the new Inferred Resource at Nizhny Endybal at various cut off grades. Table 2 the total resource on the Mangazeisky property and Table 3 the final drill results from the summer drilling program (see August 8, 2012 press release for earlier results). 

Commenting on this latest achievement, Mark Trevisiol, President and CEO said, "We have only drilled about 5,500 meters on this prospect and have identified a substantial near surface resource, which is open along strike to the north and south (see figure 2). Also, we believe there is a high potential that most of the silver from this prospect can be mined using open pit methods. This new resource represents an addition to the resources used to calculate the project economics in our Preliminary Economic Assessment ("PEA") released last year in which the mine life was 8.4 years."

Key economic parameters taken from the 2011 PEA are set out in Table 4 (see September 28, 2011 press release). The PEA used a silver production rate of approximately 4 million ounces per year over a 8.4 year mine life. The Company anticipates that this updated mineral resource estimate will be filed on its SEDAR profile by November 4, 2012.

Geological Sampling Procedures

A Quality Assurance/Quality Control program is part of the drilling program on the Mangazeisky deposits. This program includes chain of custody protocols as well as systematic submittals of standards, duplicates and blank samples into the flow of samples produced by the drilling. Prior to 2011, analysis was carried out at Russian certified laboratories in Yakutsk and Aldan, Russia. Analysis for 2012 was completed by ALS Chemex in Chita, Russia.

Mr. P. Gribble, FIMMM C.Eng, of Tetra Tech Wardrop (formerly Wardrop Engineering), is the independent qualified person who prepared the mineral resource estimates disclosed herein, and has reviewed and approved the scientific and technical information contained in this news release. 

Tetra Tech completed a NI 43-101 Technical Report supporting the mineral resource estimate. Tetra Tech also completed the PEA discussed in this news release (see September 28, 2011 news release).

Mark Trevisiol P.Eng, President and CEO of Silver Bear is the Company's designated qualified person under National Instrument 43-101 and has reviewed and approved the scientific and technical content of this press release.

Forward-Looking Information

The PEA is preliminary in nature and is based on a number of assumptions that may be changed in the future as additional information becomes available. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The PEA includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

This release and subsequent oral statements made by and on behalf of the Company may contain forward-looking statements, which reflect management's expectations. Wherever possible, words such as "intends", "expects", "scheduled", "estimates", "anticipates", "believes" and similar expressions or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved, have been used to identify these forward-looking statements. Although the forward-looking statements contained in this release reflect management's current beliefs based upon information currently available to management and based upon what management believes to be reasonable assumptions, Silver Bear cannot be certain that actual results will be consistent with these forward-looking statements.
