Following the completion of a program of infill
drilling, Tetra Tech has updated the Mineral Resource estimate for the
Vertikalny Central and Northwest deposits from the
Table 1 Updated Mineral Resource Tabulation for the Vertikalny Deposits of the Mangazeisky Property
Zone | Indicated Resource | Inferred Resource | ||||||||||
Tonnes (kt) | Grade Ag (g/t) | Contained Metal Ag (koz) | Tonnes (kt) | Grade Ag (g/t) | Contained Metal Ag (koz) | |||||||
Vertikalny Central | 800 | 909 | 23,400 | 680 | 615 | 13,400 | ||||||

Vertikalny Total | 800 | 909 | 23,400 | 990 | 565 | 18,000 |
Tetra Tech has adopted the definition of Mineral Resources as outlined within the CIM Definition Standards on Mineral Resources and Mineral Reserves (CIM, 2010) in order to classify the resources.
The effective date of the updated Mineral Resource estimate is 10th
Mineral Resource Estimation Assumptions and Methods
Key Assumptions used to estimate the updated Mineral Resource estimate are:
The estimated silver grade distribution for Vertikalny Central zone is illustrated in Figure 1.

Grade Tonnage Sensitivity
The Vertikalny block model has been reported at a range of cut-off's to provide an indication of the grade tonnage sensitivity, Table 2.

The Mangazeisky property contains a number of
satellite deposits that are being explored by Silver Bear, one of which
is Nizhny Endybal located some 3 km to the south east of Vertikalny. In

Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
Geological and 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,
