VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 18, 2011) - Sabina Gold & Silver Corp (News - Market indicators) is pleased to announce additional assay results from holes drilled as part of the 2011 exploration program on its Umwelt and Llama deposits at the Goose property and new results from exploration drilling on the George property at its 100% owned Back River Project in Nunavut, Canada.
The 2011 drilling campaign at Back River has two objectives: 1) to expand and extend the existing deposits at Umwelt and Llama, and 2) to make new discoveries using the Company's exploration tool box focussing on open pit targets on the Goose and George claim blocks, as well as the Wishbone claims retained after the Hackett River transaction.
"We are approximately half way through our drilling campaign for 2011 and we are very encouraged with our results. Drilling continues to increase the size of the Umwelt deposit and despite the complexity at Llama, we have also demonstrated that it is still open to the south," said Tony Walsh, President & CEO. "We are particularly encouraged by the success rate our "tool box" is having at the George claim block. While not all discoveries we make will be of the nature and size we are looking for, we can see that the method of applying our assumptions to make gold discoveries is working. We are very excited to start working on the many new discovery targets at Goose."
Two new discoveries have been made on the George property in 2011. The first was at Trigger (announced June 2011) and more recently at Lookout Hill. Drilling at the Lookout Hill target has returned a number of strong intercepts in Hole 11GRL022 returning 5.14 g/t Au over 16.00 including 11.31 g/t Au over 6.95 m.
The Lookout Hill discovery consists of a significant intersection of moderately folded oxide iron formation with strong quartz veining in a sheared controlled mineralized (dominantly pyrite with minor arsenopyrite) zone with visible gold. The zone is interpreted to be similar to the Llama deposit.
Drilling continues at the Lookout Hill target while further drilling options at the Trigger target are being assessed as the target is best drilled in winter conditions.
Drilling of new targets has also begun on the Goose property with assay results from the first hole of the program returning 4.10 g/t Au over 5 m within a broader zone of 2.12 g/t Au over 13.45 m in the Camp Zone. This zone is situated approximately 400 m northeast of the Goose deposit. Drilling continues on this target to evaluate its potential to become another deposit on the Goose block.
These new discoveries continue to validate the Company's strategy of applying the exploration "tool box" to finding new, potentially large scale, open pit deposits.
At Umwelt, two drills continue to infill drill the 2011 extensions of the zone. Highlights include hole 11GSE052, a resource expansion hole, approximately 500 m to the north of hole SE049, which returned 12.58 g/t Au over 26.0 m including 27.16 g/t Au over 9.0 m. This is the best hole drilled to date in the 2011 campaign. The intersection is at a vertical depth of 375 m and further demonstrates the strong continuity and grade at Umwelt.
Step-out Hole 11GSE049, the southernmost hole in which assays have been returned, has extended the Umwelt mineralized structure by a further 100 metres to 1.4 km in total. This hole returned a broad zone lower grade zone grading 2.04 g/t Au over 18.0 m including 4.17 g/t Au over 4.0 m. Hole 11GSE049 is the first hole completed on this section with the mineralization in this hole being similar to the holes drilled on the periphery of the core Umwelt deposit to the north. Further drilling will be required to define the overall grade on this section as well as continue to follow the structure south.
2011 drilling at Llama has been challenging as it is a complicated structure marked by faulting and displacement of the host iron formation as the system moves to the south. In order to maximize resources during the season, drills were redeployed from Llama to carry out other priority work on the Goose block. Since that time, assays for Hole 11GSE046 were received returning 3.57 g/t Au over 43.7 m on the East Limb, effectively extending the Llama strike length approximately 50 m south of the known zone. This hole is significant as it confirms the system is open to the south. Step-out holes are in progress to trace the mineralization further to the south.
There are currently eight drills operating at Back River. Six rigs are in the Goose area, where two are shifting from resource expansion to focussing on the numerous untested targets within the 5 km corridor containing the Goose, Llama and Umwelt deposits. One rig continues at George and one rig is operating on the Wishbone property.
To date, at Back River a total of 94 holes and 33,000 metres of core have been completed, or are in progress, with many assays still pending.
GEORGE CLAIM BLOCK
To date, a total of 32 holes comprising 6,700 m have been completed or are in progress at George.
Application of the Exploration Tool Box is also in progress at the George claim block, where the Company is looking to find new large shallow open pit deposits in the area that would enhance economics of the existing underground resource at George.
Sabina continues to experience a high level of exploration success, demonstrated by some encouraging results at the Company's Lookout Hill discovery.
The Lookout Hill target is interpreted to be similar to the Llama gold deposit. Both locations are interpreted as synformal structures with common features including a highly disrupted magnetic signature, an interpreted fault structure located centrally within the fold, a large break, an isolated magnetic feature along the eastern limb, a subtle resistivity response, as well as anomalous and significant Au samples in the area.

Target areas for priority testing at George in 2011 include the Bullwinkle, Rifle, Trigger, Lookout Hill, Shadow Pond and NZ locales, all of which are identified as having geological, geochemical, and geophysical attributes analogous to the deposits at the Goose claim block.
George contains a current indicated resource of 1,840,000 tonnes grading 10.9 g/t Au for a total of 590,000 oz and an additional inferred resource of 2,600,000 m tonnes grading 10.5 g/t Au for a total of 866,000 oz of Au and drilling of this area is 100% focused on looking for new shallow open pit discoveries.
Planned drilling has been extended at George to test the extension of this new discovery at Lookout Hill.
UMWELT
Based on last year's drilling, the Company reported indicated resources at Umwelt of 4,601,000 tonnes grading 6.0 g/t Au for a total of 900,000 oz Au and an additional inferred resource of 1,067,000 tonnes grading 6.4 g/t Au for a total of 221,000 oz Au over a strike length of 550 metres.
To date a total of 27 holes totalling 15,200 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.
Currently at Umwelt, one drill is completing 100 m step out holes tracing the deposit to the south, with two drills following behind with infill holes to advance the new mineralization to resource level. Most significantly, Hole 11GSE049, the furthest hole to the south in which assays have been returned, intersected 2.04 g/t Au over 18.0 m including 4.17 g/t Au over 4.0 m. This hole is situated 650 m south of the drilling completed in 2010 and extends the overall strike length of the deposit to over 1.4 km. It is at a vertical depth of 575 m. The deposit continues to remain open along strike and to depth and plunges at a consistent 25 degrees. Other highlights include Hole 11GSE052, an infill hole approximately 500 m to the north of Hole SE049 which returned 12.58 g/t Au over 26.0 m including 27.16 g/t Au over 9.0 m.
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.

LLAMA DEPOSIT
Based on last year's drilling the Company reported indicated resources at Llama of 1,860,000 tonnes grading 9.4 g/t Au for a total of 562,000 oz Au and an additional inferred resource of 980,000 tonnes grading 5.7 g/t Au for a total of 180,000 oz Au over a strike length of 520 metres.
Initial drilling at Llama focussed on minor gaps in the resource model and attempting to extend and expand the mineralized zone both along strike and down plunge.
To date, a total of 27 holes totalling approximately 8,700 m have been drilled or are in progress on the Llama deposit. The deposit has been challenging to expand, as it has a complicated structure marked by faulting and displacement of the host iron formation to the south.
As drilling had not been as productive as anticipated at Llama, drills were redeployed to the Umwelt and new discovery targets. However, the results from Hole 11GSE046, which returned 3.57 g/t Au over 43.7 m on the East Limb confirms that the Llama system is still open to the south along strike at more moderate grade but thicker intervals. A substantial amount of silicification, sulphidation and visible gold was noted in this hole. Two step out holes are planned by Sabina to follow-up on this assay intercept along strike.
