Sabina Gold & Silver Reports Positive Results from Early 2011 Drilling at the Hackett River Silver Rich VMS Project, Nunavut

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 18, 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 100% owned Hackett River project in Nunavut, Canada.

Hackett River, located 45 km west of the Company's Back River gold project in Nunavut, is a silver rich volcanic massive sulphide ("VMS") project and is one of the largest undeveloped projects of its type. The project contains a potentially mineable resource of approximately 60 million tonnes including an indicated resource of 200 million ounces of silver (144 g/t) and 2 million tonnes of zinc (4.65%) along with an additional inferred resource of 64 million ounces of silver (136 g/t) and 652,000 tonnes of zinc (4.46%). The project also contains appreciable copper, lead and gold.

A very encouraging preliminary economic assessment ("PEA") was completed on the project at the end of 2009 in which the project could potentially produce 13 million ounces of silver and 370 million pounds of zinc per year over 16 years through open pit and underground extraction. This scenario would generate $1.8 billion in free cash (pre-tax) and an IRR of 26%. The Company believes, however, that the project economics could be further enhanced.

Beginning in 2010 and continuing this year, work has focussed on looking for opportunities to increase through put and extend the open pit life of the operation by:

• expanding existing deposits;
• finding higher value copper/gold/silver mineralization; and
• finding new deposits.

Initial work has been focused on infill drilling large gaps in the resource model at Main Zone East and at East Cleaver. This initial drilling has been very successful in increasing both the grade and thickness in these areas of the resource model, which will ultimately improve the resource. Once these initial large gaps have been tested, drilling will be moving on to targets at the periphery of the pit shells in an effort to expand the resource.

"Our initial 2011 results at Hackett River continue to demonstrate the quality and size of these deposits," said Tony Walsh, President & CEO. "Hackett River is already one of the largest undeveloped VMS projects of its type and it is continuing to grow. Work also steadily continues to improve the grade of the project, which along with increasing size, enhances the projects already positive economics," said Tony Walsh, President & CEO. "Since the PEA was completed, we have been working hard to identify and quantify opportunities towards these objectives and continue the work this year with 70% of our work directed at infill drilling the pit shells and 30% of our work looking for new deposits on this vastly underexplored project."

Sabina opened the Hackett River camp on February 21^st and drilling for the 2011 campaign began on March 16^th. To date, 5,964 m of drilling has been completed in 24 holes with assay results returned for six.

Main Zone East

Drilling at Main Zone East highlights the precious metal-rich nature of the Hackett River deposits. The initial gap drilling has focused on shallow targets located within the proposed pits. This drilling has resulted in increased confidence in the resource model and has significantly improved the grade in many areas.

Holes SHR-11-01 and SHR-11-03 targeted gaps in the resource model at the southern end of the Main Zone East deposit. Hole SHR-11-01 was designed to test a 115 m gap between historical drilling. Hole SHR-11-01 intersected significantly higher grades in this portion of the deposit returning 268 g/t Ag, 0.52 g/t Au and 6.26% Zn over 21.70 m at a down hole depth of 122.1 m. Included were a 0.90 m interval that graded 929 g/t Ag and 4.71 g/t Au and a 0.70 m interval that graded 1,095 g/t Ag and 1.02 g/t Au.

Hole SHR-11-03 tested an 80 m gap in historical drilling and returned 141 g/t Ag, 3.65% Zn and 1.09% Cu over 43.90 m at a down hole depth of 70.4 m. Included was a 16.80 m interval that graded 266 g/t Ag and 9.03% Zn.

At the north end of Main Zone East, hole SHR-11-07 targeted a 100 m wide area where historical information was in doubt due to imprecise survey methods uses at the time. Hole SHR-11-07 intersected a number of mineralized zones over a 110.65 m section including 285 g/t Ag, 4.03 g/t Au and 2.65% Zn over 11.30 m (which also included a 1.30 m interval that graded 1,500 g/t Ag and 33.00 g/t Au) and 325 g/t Ag and 0.82 g/t Au over 8.35 m.

East Cleaver

Initial drilling at East Cleaver is also targeting extensions and gaps within the resource model with initial focus on shallow targets within the proposed pit shell. Drilling to-date continues to demonstrate the substantial thicknesses of mineralization found at East Cleaver.

Hole SHR-11-06 was designed to fill a 60 x 100 m gap in the near surface drilling of the East Cleaver deposit and returned 134 g/t Ag and 5.47% Zn over 99.75 m starting at a down hole depth of only 5.0 m. This interval included is a silver-rich copper stringer zone which graded 298 g/t Ag, 0.52 g/t Au and 1.10% Cu over 10.45 m and a zinc-rich massive sulphide interval that graded 264 g/t Ag and 11.73% Zn over 10.90 m.
