Sabina Silver Hires AMEC Americas Limited for Engineering Services as the Silver-Zinc Hackett River Project Advances

VANCOUVER, BC--(Marketwire - May 31, 2007) - SABINA SILVER CORPORATION (TSX-V: SBB) ("Sabina") is pleased to announce that it has signed an agreement for provision of technical support services and pre-feasibility assessment of its Hackett River Project in the Nunavut Territory, Canada with AMEC Americas Limited ("AMEC").

AMEC is a full service engineering company with extensive engineering, procurement and construction management experience on many mining projects around the world including a variety of development/mining projects in the Arctic region of Canada and Alaska.

A recent NI 43-101 compliant Preliminary Economic Assessment of the Hackett River Project has indicated potential production levels of over 12 million ounces silver and 147,000 tonnes zinc per year plus appreciable copper, lead and gold, for a mine life of 13.6 years. The project generates a C$257 million NPV at a full 10% discount rate using conservative metal prices of US$8.69/oz silver, US$0.72/lb zinc, US$1.35/lb copper, US$0.39 lead and US$522.50/oz gold (March 5, 2007).

Drilling activities are fully underway at Hackett River at present. The 2007 work plan includes additional definition drilling to expand the resource, geotechnical drilling and testing for open pit and underground design, further metallurgical testing and optimization, geophysical surveys of additional exploration target areas and initiation of a formal environmental impact assessment process. The information expected from the 2007 work plan will move the Hackett River Project towards an NI43-101 compliant pre-feasibility study later in the season. The total approved exploration and development budget for the Hackett River Project is C$15 million for 2007.

Sabina will also drill two highly encouraging silver-zinc exploration targets at Hackett River in 2007. These occur along strike from the principal resource area within the main host exhalite horizon. These include the Jo Zone resource area previously identified by Cominco and the Patricia Zone, which exhibits a large gravity anomaly and has 4 holes historically showing stratigraphic and geophysical similarities to the three deposits comprising the NI43-101 compliant mineral resource at Hackett River (East Cleaver, Boot Lake and Main Zone).

Sabina will also expend approximately C$700,000 on drilling of high grade silver and gold zones at the Del Norte project in the Stewart-Eskay Creek Mining District which is due to commence shortly. The company now has personnel on the ground and will also expend just over C$1 million to identify and drill gold targets on the Golden Sidewalk and Skinner exploration projects in the Red Lake gold camp of Ontario. The company will also expend up to C$450,000 for initial exploration of the newly acquired Rockstone zinc-silver project in the Thunder Bay Mining District. A recently flown airborne magnetic and electromagnetic survey has identified a variety of promising targets for follow up work.

Silver Corporation has current working capital cash and investments of over $60 million and is well funded to advance all its projects to the next level of value. The Qualified Person reviewing and approving this news release is Abraham Drost, P.Geo.
