Sabina Gold & Silver Reports Positive Results From Early 2011 Drilling at the Back River Project, Nunavut

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 27, 2011) - Sabina Gold & Silver Corp (TSX:SBB) is pleased to announce significant assay results from the first holes drilled as part of the 2011 exploration program on its Umwelt and Goose deposits at its 100% owned Back River Project in Nunavut, Canada.

The 2011 drilling campaign at Back River started on the Goose claim block in March. To date, a total of 39 holes and 7,872 metres of core have been completed or are in progress, with most assays still pending.

The focus of work in 2011 is to extend and expand the new deposits at Llama and Umwelt, as well as, identify potential new deposits not only on the Goose claim block but elsewhere on the Back River property.

A total of four rigs are currently drilling at the Goose claim block, generating approximately 300 metres of core per day. The four drill rigs are focusing on resource expansion at Llama and Umwelt. Each deposit has one drill completing aggressive 100 metre step outs to the south with a second drill following up with 50 metre infill holes.

2010 drilling had extended the Umwelt corridor of mineralization approximately 750 m along strike. However, only 535 m of strike length had been drilled sufficiently to enable a resource calculation on that deposit. The new drill holes reported today now extend the Umwelt mineralized zone by a further 200m to the south along strike. Hole 11GSE009 drilled 100 m south of last year's drilling returned 10.14 g/t Au over 25.0 m including 16.62 g/t Au over 10.0 m. Hole 11GSE016 drilled 100 m south of Hole 11GSE009 returned 5.55 g/t Au over 19.2 m including 25.39 g/t Au over 2.2 m at a vertical depth of 340 m. Most assays remain pending however it is encouraging to note that grades and widths to date are similar to those encountered in the 2010 drilling program. Both Llama and Umwelt remain open along strike.

Initial 2011 drilling also targeted the Goose deposit to aid in the geological/resource modelling interpretation in support of a calculation of an open pit resource. Most significantly, hole 11GSE002 returned 18.99 g/t Au over 27.2m including 63.51 g/t Au over 4.1m at a vertical depth of 170 metres in a central area of the deposit that was originally thought to be barren. The historical Goose resource is being recalculated to include recent drilling and new resource modelling to determine its potential as an open pit. This calculation is nearing completion and is expected within the next 3-4 weeks.

A fifth rig will be operational shortly and will begin testing regional targets at the Goose claim block.

"Our 2011 drilling campaign is off to a good start," said Tony Walsh, President & CEO, "While 70% of our $30 million Back River budget is focussed on extending the deposits at Llama and Umwelt, we are also very excited about applying our exploration tool box to find new discoveries. At the Goose claim block there are over 15 such targets alone and we have started to direct some of our resources to these anomalies."

The new deposits and target areas at Goose are within a 5 km corridor that have been identified using an exploration tool box developed by Sabina's geological team. This new tool box is based on a set of assumptions that specifically target large buried alteration and mineralized features in folded iron formation units. These types of folded units have the potential to be extracted by open pit methods.

Initial exploration drilling is also underway at the George claim block where two drills are testing large, shallow but covered alteration and mineralization targets similar to that at Llama and Umwelt. The George deposit contains an existing indicated resource of 590,000 oz of Au and an additional inferred resource of 866,000 oz of Au at an average grade of 10.5 g/t Au. While the George deposit itself is more amenable to underground mining methods, the development and application of the new tool box has identified numerous opportunities to find additional large shallow open pit deposits close to the existing resource.

UMWELT

Drilling at Umwelt is planned to extend and expand the mineralized zone both along strike and down plunge.

To date a total of eight holes totalling 3,773m have been drilled or are in progress on the Umwelt target. Assay results have been returned for four holes.

New results include step-out holes 11GSE009 located 100 metres south of the drilling completed in 2010 and 11GSE016 located a further 100 metres south of 11GSE009. Hole 11GSE009 returned 10.14 g/t Au over 25.0m including 16.62 g/t Au over 10.0m. Hole 11GSE016 returned 5.55 g/t Au over 19.2m including 25.39 g/t Au over 2.2m at a vertical depth of 340 metres within the Main Zone.

In addition, results have been returned for holes 11GSE001 and 11GSE006 which targeted the Main Zone immediately below the southern extent of the 2010 drilling. Hole 11GSE001 returned 5.62 g/t Au over 23.3m including 13.70 g/t Au over 5.2m in Main Zone East limb and 15.27 g/t Au over 3.0m in Main Zone West limb. Hole 11GSE006 returned 6.72 g/t Au over 12.5m within a broader zone of 3.40 g/t Au over 31.33m.

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. The relationship between the Main and West zones is uncertain but the West Zone may be a refolded limb of the Main zone.

True widths are estimated to be 70% of the drill widths. Interpretation is currently in progress to confirm the geological relationships at the Umwelt deposit.

Llama Deposit

Initial drilling at Llama focussed on gaps in the resource model and going forward, the plan is to extend and expand the mineralized zone both along strike and down plunge.

To date, a total of 13 holes totalling 2,939m have been drilled or are in progress on the Llama deposit target. Assay results are still pending.

Goose Deposit

A total of 3 holes totalling 590 metres were drilled on the Goose deposit. The holes were drilled to provide information for the ongoing geological / resource modelling interpretation in support of an open pit resource estimate.

Hole 11GSE002, located on local grid section 5180N, was drilled to validate the interpretation that an early hole drilled on this section is inappropriately located due to erroneous down hole deviation tests. Hole 11GSE002 returned 18.99 g/t Au over 27.2m including 63.51 g/t Au over 4.1m at a vertical depth of 170 metres. Both the geology and mineralized zones correlates very well with adjacent holes confirming the interpretation.

Hole 11GSE004B, located on local grid section 4730N targeted a gap in the drilling of the greywacke core within the folded iron formation. The hole intersected numerous gold bearing mineralized zones within the greywacke unit including 9.57 g/t Au over 3.0m at a vertical depth of 55 metres. Currently the known mineralization within the greywackes represents only a small portion of the overall Goose deposit resource. There is excellent potential to expand this greywacke component of the resource with further drilling particularly in an open pit scenario.

RESOURCE UPDATES

The Company has retained RPA to prepare a new resource estimate for the original Goose deposit based on an open pit model. This estimate is due shortly and if positive, the Company anticipates moving to a scoping study in mid-2011.

GEORGE LAKE DRILLING

Diamond drilling started at George in mid April using two rigs to explore for near surface open pitable targets. No assay results have yet been received. A total of six initial high priority target areas have been defined using Sabina's toolbox with the intention of discovering another Banded Iron Formation gold hosted deposit comparable to Goose, Llama or Umwelt. Approximately 4,000 to 6,000m of drilling is planned as part of the initial phase of exploration drilling. The George property is located 60 km northwest of the Goose property.
