Sabina Gold & Silver Reports Updated Mineral Resource Estimate for the Back River Gold Project, Nunavut

Increase in overall contained Au ounces in the Measured, Indicated and Inferred Resource categories

Significant Increase in Measured Au ounces from 304,000 ounces at 4.4 g/t Au and 2,168 kt to 1,714,000 ounces at 5.2 g/t Au and 10,210 kt for open pit

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Mar 4, 2014) - Sabina Gold & Silver Corp. (TSX:SBB) is pleased to announce an updated Mineral Resource estimate for its 100% owned Back River Gold Project in Nunavut, Canada ("Back River or the "Project").

The updated Mineral Resource Estimate for Back River was undertaken by AMC Mining Consultants (Canada) Ltd. ("AMC"). This new estimate consists of a Measured Mineral Resource of 10.4 million tonnes grading 5.2 g/t for a contained 1,761,000 ounces Au, an Indicated Mineral Resource of 17.9 million tonnes grading 6.1 g/t for a contained 3,536,000 ounces Au and an Inferred Mineral Resource of 8.2 million tonnes grading 7.3 g/t for a contained 1,927,000 ounces Au. Results from drilling in 2013 and geologic modelling on all deposits has increased the Mineral Resource estimate at Back River.

"In 2013, we completed a very significant drill program of approximately 83,000 metres at Back River, none of which was included in the Back River pre-feasibility study ("PFS") released last fall," said Rob Pease, President & CEO, "The resulting increase in overall Mineral Resources and substantial increase in confidence in the continuity and grade of the deposits continues to demonstrate the high quality nature of the Back River Gold Project. We believe this increased Mineral Resource Estimate will increase the potential for a larger Mineral Reserve on the project. Additionally, we continue to make progress on optimization studies which could present opportunities for improved gold recovery and mining methods, the results of which will ultimately be used to support a Feasibility Study ("FS").

We believe we have a premier project, in a premier geopolitical jurisdiction, with a well-funded treasury. Sabina ended 2013 with approximately $58 million in the treasury, which will enable us to advance through permitting and engineering studies with a surplus of cash on hand. We are very excited about the next phase of growth for our Company as we work to become a gold producer."

Highlights of the new Mineral Resource estimate include:

• Increase in Measured Au ounces from 304,000 ounces at 4.4 g/t Au and 2,168 kt to 1,714,000 ounces at 5.2 g/t Au and 10,210 kt for open pit and 47,000 ounces at 6.1 g/t Au and 236 kt for underground
• Increase in total contained Au ounces of 735,000 in the Measured and Indicated Resource categories and 48,000 in the Inferred Resource category
• Significant open pit Measured plus Indicated Mineral Resource of 3,415,000 ounces at 5.0 g/t Au and 21,066 kt
• Underground Measured plus Indicated Mineral Resource of 1,881,000 ounces at 8.0 g/t Au and 7,288 kt

A NI 43-101 Technical Report on the updated Mineral Resource estimate for Back River is underway and will be filed within 45 days of this release in accordance with applicable securities laws. The new Mineral Reserve and economics for the Project are yet to be estimated and will be incorporated into a FS.

Table 1 - Back River Mineral Resource Estimate February 28, 2014

1. CIM definition standards were used for the Mineral Resources.
2. The Qualified Persons are Dinara Nussipakynova, P Geo. and Andrew Fowler MAusIMM CP (Geo) both of AMC Mining Consultants (Canada) Ltd.
3. Open pit Mineral Resources are constrained by an optimized pit shell at a gold price of $1500 oz Au.
4. The cut-off grade applied to the open pit resources are 1.0 g/t Au. The underground cut-off grade for Goose Main, Echo, and Llama deposits is 3.5 g/t Au; and for Umwelt is 4.5 g/t Au. The underground cut-off grade for the George resources is 4.0 g/t Au.
5. Metallurgical recovery varies with gold grade, averaging between 88 and 89%.
6. The George underground Mineral Resources (LCP - North, LCP - South, Locale 1, Locale 2, GH & Slave) were estimated within mineral domains expanded to a minimum width of 2 m.
7. Drilling results to December 31, 2013 were used.
8. The increase in Measured Resources at Goose Main is attributed to re-verifying and resolving previous conflicts of historical surveys and geological data. This has resulted in increased confidence in interpreted geologic continuity and subsequently an increase in resource confidence.
9. Numbers may not add due to rounding.
10. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Infill drilling in 2013 allowed Measured Resources to be classified at Llama and Umwelt for the first time. Gold price and cut-off grade assumptions remained the same as those used for the PFS for the updated Mineral Resource estimates, with the exception of Llama and Goose Main underground. For these two areas the cut-off grade was changed from 4.0 g/t to 3.5 g/t and for Umwelt underground the cut-off grade was changed from 5.0 g/t to 4.5 g/t. The cut-off grade changes reflected the final cost estimates generated in the PFS. The increase in Measured Resources at Goose Main is attributed to re-verifying and resolving previous conflicts of historical surveys and geological data. This has resulted in increased confidence in interpreted geologic continuity and subsequently an increase in resource confidence.

Background and Work Plans 2014

The Back River gold project is located in the West Kitikmeot Region of Nunavut, a new territory of Canada very supportive of responsible mineral resource development and exploration. The project has access to tide water and is situated approximately 75 km from Bathurst Inlet.

The Project is made up of a series of seven claim blocks of which only two have been the primary focus of exploration and resource development to date: Goose and George.

In October 2013 Sabina published a PFS for the Project prepared under the leadership of Tetra Tech by leading industry consultants. The Back River PFS is based on a conventional open pit mine supplemented by underground operations that feed a 5,000 tonne per day whole ore leach process plant. Operations are designed to produce an average of 287,000 ounces Au per year over the life of mine. The Project would be built over a 24-month period at an initial capital cost of $605 million with an estimated payback of 3.3 years from the start of operations.

In 2014, Sabina intends to continue to advance the Back River Project towards completion of a FS with:

• A potential resource expansion drilling program in and around the new resource at Echo. As Echo is on the Goose property, work to bring this resource into the mine plan could have a positive impact on project economics as satellite mining at George can be pushed further into the mine life.
• Ongoing optimization studies to support the FS, including metallurgical testing, mining method and schedule optimizations and additional trade-off studies. These activities are anticipated to be completed by the end of the first quarter.
• Continuation of the environmental assessment and permitting process including the collection of additional environmental baseline data.

The Company expects to initiate a full FS later this year once all optimization studies are complete and analyzed. It is anticipated that results of these various studies will be reported throughout the year. The budget and work program for 2014 will be announced towards the end of the first quarter.
