White Tiger Gold Ltd. Announces Discovery of New Gold Mineralization Zone
Highlights
- Recent drilling completed in February of this year has resulted in the discovery of a major zone of gold mineralization located immediately to the southwest of the current open pit operation.
- Limited drilling to the northeast of the open pit has also encountered oxide gold mineralization but requires additional drilling to define the dimensions of the mineralized zone.
- A total of 106 diamond drill holes were completed in the Southwest Flank Zone on 50 and 100m sections at 50m intervals for a total of 11,682m.
- The drilling has outlined two zones of gold mineralization with a combined strike length of 1200 m, ranging up to 270 m in width and tested to a vertical depth of 160 m. Potential exists to join the two zones of mineralization with additional drilling.
- Potential exists to extend the zone of gold mineralization along strike and at depth.
- Gold mineralization is developed along the Savkino Fault. The fault has been traced intermittently over a strike length of 6 km of which only 2.5 km has been drill tested.
- Extensive alluvial gold mineralization is sourced from Permian granites located in the northwest part of the license area. This area also contains numerous bedrock Zn-Pb-Ag-Au-Sn prospects which have not been drill tested.
- Cyanide bottle roll leach tests conducted by SGS Mineral Services Chita, Russian Federation, are currently in progress to determine metallurgical recovery of gold.
- Micon International Co Limited has been contracted to undertake a mineral resource estimate for the Southwest Flank gold mineralization which is expected to be available within 6-8 weeks.
Mine Location
The Savkino heap leach oxide gold mine is located in the Zabaikal Region of southeast Siberia in the Russian Federation. The mine is situated approximately 400 km from Chita, the administrative capital the Region and 15 km west of the north border of China. Access to the mine is afforded by the Chita-Khabarovsk federal highway to Priargunsk and then serviced by all-weather gravel road to the mine site.
Savkino Gold Deposit
The Savkino gold deposit lies in the Eastern Trans-Baikal polymetallic belt and the license areas host a wide variety of base and precious metal occurrences in addition to areas of placer gold mineralization.
The Savkino mineralization exhibits geological and geochemical characteristics analogous to Carlin-type disseminated gold deposits. Gold mineralization is partly controlled by a steeply-inclined, reverse-faulted curvilinear contact between Cambrian and Jurassic stratigraphic units which is intermittently exposed over a strike length of 6 km.
The majority of the gold mineralization is hosted primarily by Cambrian dolostone, siltstone and shale favoring the footwall limb and hinge zone of the asymmetrical to recumbent Savkino Anticline. Lower grade discontinuous mineralization is also developed in the hangingwall of the Anticline Mineralization. The mineralization has no clear geological boundaries or preferred host rocks and is defined on the basis of sampling and assaying.
The Central Zone of oxide gold mineralization which is currently being mined extends for a strike length of 950 m and has been traced to a minimum depth of 175 m and is open down dip. Historical wide spaced drilling over the Northeast and Southwest Flanks intersected near surface disseminated oxide gold mineralization. The 2010-2011 drilling program reported herein was designed to test the potential extension of the Central Zone mineralization.
Savkino Deposit Mineral Resources and Mineral Reserves
The Savkino mineral resource and mineral reserve estimates were prepared by Micon International Co Limited (“Micon“) in 2010 following CIM guidelines in compliance with National Instrument 43-101 (“NI 43-101“). Such estimates are respectively set out below in Tables 1 and 2.

Savkino Production Details
The Savkino gold deposit was approved for construction and commencement of operations by the Federal authority Glavsgosexpertiza on May 30, 2008. Mining is from an open pit at 1,823 t/day with heap leach cyanide extraction process.
The first gold doré was produced in October 2008 and to date the mine has produced 28,379 ounces of gold.
During 2010, the Savkino heap leach operation produced 15,157 ounces of gold at an average recovery of 79.7%. The average head grade of the ore was 1.29 g/t Au.
2010-2011 Drilling Southwest Flank Zone
A total of 106 diamond drill holes were completed on 50 and 100 m sections at 50 m intervals for a total of 11,682 m. The drilling has defined two mineralized bodies. The 100 m gap between the mineralized bodies has not been drilled due to lack of soil geochemical and geophysical responses. The Company believes that potential exists to join the two zones of mineralization with additional drilling.
Oxidation is variable in the Southwest Flank Zone with minor sulphides present in some of the drill holes. Primary gold mineralization is associated with variable silicification and fine quartz vein stockwork with minor disseminated pyrite and marcasite. Oxide-type mineralization is associated with intensive clay-iron oxide alteration and silicification, with the highest gold grades occurring in zones of faulting, shearing and brecciation.
The largest and most continuous mineralized body to the southwest extends over a strike length of 780 m and variable width from 50 to 200 m, with variable dip 40 to 70°SE and intersections to 160 m vertical depth. Mineralization occurs in two subparallel structural zones which are highly variable in thickness along strike and down dip.
The second mineralized body closest to the mine in the Central Zone has similar mineralogical characteristics as the oxide zone in the main body, but continuity has not been confirmed due to irregular drill spacing. This zone extends approximately 420 m along strike and 270 m wide. The zone dips 40 to 50°SE and has been intersected to a maximum depth of 120 m.
The Company is presently undertaking cyanide assaying on all fire assay results ≥0.2 g/t Au to determine the leaching characteristics of the gold mineralization.
The drill hole statistics and significant assay intervals greater than or equal to 0.3 gpt Au are summarized in Table 3 below.
Micon has been involved with the Savkino project since its inception and is intimately familiar with all aspects of the mining operation. Micon has been contracted to undertake a mineral resource estimate for the Southwest Flank Zone. The Company anticipates such estimate will be available within 6-8 weeks.
Regional Potential Savkino License Area
Extensive alluvial gold mineralization is sourced from Permian granites located in the northwest part of the license area. This area contains numerous bedrock Zn-Pb-Ag, and Ag-Au prospects, which have not been drill tested. In addition, four significant Ag-Au soil anomalies have been defined within and along the contact of the Permian granitic batholiths. The most significant Ag soil anomaly measures 3 km in length and up to 1.5 km in width and is coincident with a strong IP chargeability high.
Sample Preparation, Analytical Protocol and Quality Control
Analytical samples were taken from half core cut with a diamond saw and composited over 1 m intervals. Samples were prepared at site by Vostokgeologiya LLC, an independent government approved geological contracting company, and assayed at the independent commercial laboratories of ALS Laboratory Group and SGS Mineral Services in Chita.
Samples were crushed to 100% passing -5 mm, sub-sampled using a rotary sample divider, recrushed to -2 mm and pulverized to 95% passing 75 microns, and sub-sampled to 200 g submitted to the commercial laboratory. Control samples, including 4 Certified Reference Material (CRM), 5 pulp duplicates and 3 blanks were inserted with each analytical batch of 100 samples. CRM and blank material is internationally certified and supplied by Geostats Pty Ltd in Australia and Rocklabs Ltd. in New Zealand (each independent of the Company).
Analytical results of control samples indicate there is no apparent analytical bias or systematic contamination of samples, and accuracy is within the stated specifications of the CRM.

Additional information about these assumptions and risks and uncertainties are contained in the Company's filings with securities regulators, including its management's discussion and analysis dated March 30, 2011 (available on SEDAR at www.sedar.com). All of the forward-looking information made in this news release is qualified by the foregoing cautionary statements and those made in the “Risk Factors“ section of the Company's most recently filed Annual Information Form dated March 30, 2011.
Mineral resources are not mineral reserves and do not have demonstrated economic viability. Inferred mineral resources are estimated on limited information not sufficient to verify geological and grade continuity or to allow technical and economic parameters to be applied. Inferred mineral resources are too speculative geologically to have economic considerations applied to them to enable them to be categorized as mineral reserves. There is no certainty that mineral resources can be upgraded to mineral reserves through continued exploration.
