Sabina Gold & Silver Reports Continued Resource Expansion at the Umwelt Deposit, Back River Gold Project, Nunavut
New High Grade Umwelt G2 Zone being Defined
Hole 11GSE121 at Umwelt returns 14.24 g/t Au over 28.25 m including 29.96 g/t Au over 8.35 m
Hole 11GSE092 at Umwelt returns 6.18 g/t Au over 23.20 m
New assay results expand the mineralized zone width in
previously released Hole 11GSE096 at Umwelt returning 5.19 g/t Au over 60.2m
The 2011 drilling campaign at Back River has been focussing on expanding the existing deposits at Umwelt and Llama, and looking for new discoveries by applying the Company’s exploration tool box to open pit targets on the Goose and George claim blocks, as well as the Wishbone gold claims.
The Umwelt deposit, discovered in 2010, contains an indicated resource of 4.6 m tonnes grading 6.0 g/t Au for a total of 900,000 ounces of Au and an inferred resource of 1.1 m tonnes grading 6.4 g/t Au for a total of 221,000 ounces of Au. Drilling in 2011 has extended this resource approximately 900 m along strike to the south. The Umwelt deposit has now been defined over a 1.15 km strike length and for 1.5 km down plunge and remains open.
Recent drilling at depth of the southern extension of Umwelt continues to encounter high grade thick mineralization in a zone called the Umwelt G2 Zone (G2 stands for, Good grade and Good Thickness). This zone is at a depth of approximately 600 m and is open dip and down plunge to the south. The strong grade and thickness of the zone is typified by recently completed hole 11GSE121 which returned 14.24 g/t Au over 28.25 m. The G2 Zone is the direct extension of the wide mineralized zone that makes up the proposed open pit at Umwelt and appears to have a stronger gold tenor.
“Our work continues to demonstrate the high quality of the Back River Property. In our 2011 campaign, we have extended and expanded our Umwelt and Llama deposits and we have made eight new discoveries on our Back River and Wishbone claims with many assays still pending.” said Tony Walsh, President & CEO “We are very encouraged by the success we are having in identifying good grades and good widths in our deposit areas. On the discovery front we are very encouraged by recent developments. While not all discoveries we make will be of the nature and size we are looking for, our success rate in finding gold mineralization based on the limited number of targets tested this year is excellent. This demonstrates the prospective nature of the land package we have at Back River and Wishbone and we are confident that we will continue to make new discoveries.”
To date, at Back River a total of 175 holes and 61,800 metres of core have been completed, or are in progress, with many assays still pending. Drilling will continue with two drills at Umwelt until approximately October 1, 2011.
To date a total of 63 holes totalling 33,350 m have been drilled or are in progress on the Umwelt zone at the Goose property. Results continue to demonstrate that Umwelt is a strong, well mineralized system with excellent continuity and grade.
New results have been returned for three holes completed in what is now called the Umwelt G2 Zone. Hole 11GSE121 on section 4050N returned 14.24 g/t Au over 28.25 m including 29.96 g/t Au over 8.35 m at a depth of 600 m. Hole 11GSE092 on section 4150N returned 6.18 g/t Au over 23.20 m including 7.28 g/t Au over 18.35 m. A number of additional lower grade zones were also intersected in this hole. Hole 11GSE102BW on section 4000N returned 7.62 g/t Au over 10.00 m including 29.45 g/t Au over 2.00 m. Bounding assays for all of these intercepts have yet to be returned. New assay results have increased the width of the mineralized zone in previously released Hole 11GSE096 collared on section 4400N. Hole 11GSE returned 5.19 g/t Au over 60.2m. Recently returned assay results from Umwelt are summarized in Table 1.
The mineralized zones are hosted within a turbiditic sedimentary sequence containing silicate and oxide facies iron formations. Gold dominantly occurs with quartz +/- carbonate veining and arsenopyrite +/- pyrite +/- pyrrhotite in the iron formation. Drilling at Umwelt has identified an anti-form structure with a fold hinge that plunges to the south. Thick zones of gold mineralization are associated with the fold hinge in what is now known as the Main Zone. Mineralization also occurs along a separate iron formation horizon immediately to the west known as the West Zone.
On September 20, 2011, the Company announced an updated resource for the Goose deposit. Goose, Llama and Umwelt sit within a 5km long corridor and are envisioned as three major open pits supporting one central milling facility at the Goose claim block. The George deposit, located approximately 50 km to the north on the George claim block, is envisioned as an underground satellite deposit that would be mined and transported to the mill at Goose via winter road. The Company has recently engaged SRK Engineering Ltd. to commence work on a Preliminary Economic Assessment of a gold mining operation at Back River. The study will comprise the new open pit Goose resource, the soon to be updated Umwelt and Llama resources (incorporating 2011 drilling) as well as the existing George resource. The study is anticipated to be completed early in 2012, after which, if positive, a Preliminary Project Description will be filed with the Nunavut Water Board to initiate the permitting process for the project.

Sabina Gold & Silver Corp. is an emerging precious metals company with district scale, world class undeveloped assets in one of the world’s newest, most politically stable mining jurisdictions: Nunavut, Canada.
Sabina’s primary properties consist of the Back River Gold Project as well as the Wishbone Claims, a vastly prospective grass roots project and the Hackett River poly metallic project all in Nunavut. The Company has announced a proposed sale of Hackett River and certain claims in the Wishbone greenstone belt to Xstrata Zinc Canada Division (Xstrata). The process to close the transaction with Xstrata is well underway and is expected to close shortly.
