Silver Standard Expands Mineral Resources at Marigold with Higher Gold Grade Mineralization

VANCOUVER, Dec. 12, 2014 /CNW/ - Silver Standard Resources Inc. (NASDAQ: SSRI) (TSX: SSO) ("Silver Standard") is pleased to announce the addition of Mineral Resources at the Marigold mine ("Marigold") located in Humboldt County, Nevada. These Mineral Resources lie within the limits of Marigold's existing plan of operations at the southern end of the 8 South pit and are comprised of oxidized gold mineralization, leachable using the current run-of-mine heap leach process. The 8 South pit extension currently contains Indicated Mineral Resources of 2.13 million tonnes at a grade of 1.20 grams per tonne gold and Inferred Mineral Resources of 1.70 million tonnes at a grade of 1.41 grams per tonne gold. The gold mineralization is open to the south, east and west. The grade of these Mineral Resources compares favourably to the Marigold mine average reserve grade of 0.51 grams per tonne gold.

"Exploration efforts at Marigold continue to deliver positive results," said John Smith, President and CEO. "Our goal was to confirm our understanding of the geology and to identify extensions to existing pits for higher margin ounces. The results of our 2014 drill program have exceeded our expectations due to the gold grade encountered and the proximity to the historical 8 South pit."

Category	Tonnes	Gold Grade	Contained Gold
	(Mt)	(g/t)	(oz)
Measured	-	-	-
Indicated	2.13	1.20	82,000
Inferred	1.70	1.41	75,000

Notes:
1.	James N. Carver, Registered SME Member (# 509390), is the Qualified Person for the Mineral Resources estimate. For a complete description of the key assumptions, parameters and methods used to estimate the Mineral Reserves and Mineral Resources at Marigold, please refer to the technical report dated November 19, 2014 and entitled "NI 43-101 Technical Report on the Marigold Mine, Humboldt County, Nevada", which is available under our profile on the SEDAR website at www.sedar.com or on our website at www.silverstandard.com.
2.	The Mineral Resources estimate has been classified in accordance with Canadian Institute of Mining, Metallurgy and Petroleum (CIM, 2010) definition standards.
3.	Reported Mineral Resources are estimated below the as-mined surface as at November 30, 2014 and are inclusive of Mineral Reserves.
4.	Gold values have been estimated using ordinary kriging.
5.	Outlier restriction on gold values above 8.00 g/t has been used for the Mineral Resources estimate.
6.	Densities for different lithological units have been calculated based on detailed test work carried out by Silver Standard and corresponds to the historical mine production.
7.	The Marigold drillhole database including collar survey, assay, lithology, oxidation and densities used for this Mineral Resources estimate has been verified by James N. Carver, SME Registered Member, by conducting detailed verification checks, including Quality Assurance/Quality Control of location, geological, density and assay data.
8.	Mineral Resources include all mineralized material that has the potential for economic recovery of gold from an open pit supply to a run-of-mine heap leach operation.
9.	The Mineral Resources estimate has been calculated based on an optimized pit at a cut-off grade of a payable gold grade of 0.065 g/t (gold assay factored for recovery, royalty and net proceeds per mineral resource block) with a gold price assumption of US$1,500 an ounce.
10.	The cost, recovery and design parameters considered by optimization calculations for this Mineral Resources estimate are considered appropriate based on the current mine production.
11.	The reported Indicated Mineral Resources are regarded as appropriate for medium to long term production open pit planning and mine scheduling on a quarterly basis.
12.	Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. While the classification categories of Mineral Resources used in this news release are recognized and required under Canadian regulations, the U.S. Securities and Exchange Commission ("SEC") does not recognize them and U.S. companies are generally not permitted to disclose resources in documents they file with the SEC.
13.	There are no known legal, political or environmental risks that could materially affect the potential development of the Mineral Resources at Marigold.
14.	Tonnage and grade measurements are in metric units. Contained gold ounces are reported as millions of troy ounces (Moz.).
15.	Only oxidized gold mineralization, amenable to Marigold's existing recovery process, is considered for these estimates.
16.	Figures may not total exactly due to rounding.

The Mineral Resources are located along the southern edge of the previously mined 8 South pit. The 8 South pit produced 530,000 ounces of gold at a grade of 1.51 grams per tonne and supported a milling operation between 1987 and 1994. The gold distribution at the 8 South area is controlled by the Sear Fault, a north-south striking high-angle fault, which extends south of the historic mining area and had not been fully drill-tested. The recently completed exploration work demonstrates the lateral continuation and splaying of the Sear Fault with mineralization now open to the south, east and west. Selected results from the 2014 drill program that illustrate higher-grade gold intercepts have been included in Figure 1 and Table 2.

Next steps

Based on these positive results, the exploration program on the 8 South pit area has been extended with an additional 2,600 meters, in 10 drill holes, to be completed by year-end 2014. It is expected that these drill results and the additional Mineral Resources will be included within the annual 2014 Mineral Resources and Mineral Reserves statement to be published in the first quarter of 2015. The Marigold mine has begun an evaluation to determine the readiness of these Mineral Resources for mining.

Cautionary Note to U.S. Investors

This news release includes Mineral Reserves and Mineral Resources classification terms that comply with reporting standards in Canada and the Mineral Reserves and the Mineral Resources estimates are made in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the requirements of the SEC set out in Industry Guide 7. Consequently, Mineral Reserves and Mineral Resources information included in this news release is not comparable to similar information that would generally be disclosed by domestic U.S. reporting companies subject to the reporting and disclosure requirements of the SEC. Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically produced or extracted at the time the reserve determination is made.
