Silver Standard Reports Silver and Zinc Mineralized Intercepts From Three Target Areas at Pirquitas07:00 EDT Tuesday, September 11, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 11, 2012) - Silver Standard Resources Inc. (TSX:SSO)(NASDAQ:SSRI) ("Silver Standard" or the "Company") reported silver and zinc mineralized intercepts from three target areas at its Pirquitas mine in Jujuy, Argentina. Select assay results for the recently completed drill holes include: Cortaderas Breccia Target:DDH-238: 27 meters at 202 g/t Ag and 9.8% Zn DDH-241: 164 meters at 97 g/t Ag and 3.9% Zn DDH-243: 23 meters at 388 g/t Ag and 9.7% Zn Oploca Vein Depth Extension:DDH-244: 0.6 meters at 7,600 g/t Ag and 16.9% Zn 2.5 meters at 469 g/t Ag and 2.5% Zn 2.0 meters at 2,280 g/t Ag and 0.1% Zn DDH-247: 1.65 meters at 119 g/t Ag and 7.3% Zn Portal Drilling Target:DDH-237: 7 meters at 426 g/t Ag and 1.6% Zn DDH-239: 16 meters at 61 g/t Ag and 4.4% Zn Ron Burk, Vice President of Exploration, commented: "These drill results demonstrate that the Cortaderas Breccia deposit extends beyond the eastern limits of the Inferred Mineral Resource reported last November. Specifically, holes DDH-238, DDH-241 and DDH-243 were drilled, respectively, 50, 75 and 110 meters to the east of DDH-2301, and contain significant silver and zinc mineralization." The Company has also received assay results for four drill holes located between the southern edge of the San Miguel open-pit and the Oploca vein system. The mineralized intercepts in drill holes DDH-244, DDH-245 and DDH-247 are interpreted to be intersections of the Oploca vein system between 200 and 250 meters below the historic underground workings2. These results indicate that a resource target exists at Oploca with an east-west dimension of at least 200 meters and a vertical extent of about 250 meters. Silver Standard also received encouraging assay results from drill holes that tested the Portal Drilling Target, a gravity survey anomaly centered approximately 200 meters south-west of the San Miguel open-pit. As shown in Table 1, three of the reported four holes encountered silver-bearing sulphide mineralization. Given the success in applying the gravity-based method of geophysical surveying to detect buried sulphide mineralization at Pirquitas, the Company has commissioned a second phase of gravimetrics surveying over the eastern portion of the mine property. As announced in July, the Company recently accelerated its Pirquitas drilling program by adding a third drilling rig. As of September 6th, the Company had completed approximately 34,000 meters of an expanded 40,000-meter drilling program on the property. The drill program is designed to increase Silver Standard's previously estimated Cortaderas Valley and Cortaderas Breccia Inferred Mineral Resources as described in our NI 43-101 compliant technical report dated December 23, 2011. Periodic updates will be provided as assay results become available.Details of the mineralized drill hole intervals reported in the news release are presented in Table 1, with the locations of the holes shown in Figure 1. The reported drill holes in the Cortaderas Breccia target area are oriented at shallow angles to the inferred plunge orientation of the mineralized breccia body. The current drilling program includes drill holes that will intersect the mineralized breccia zone at orientations that are expected to enable the Company to estimate the true dimensions of the body. Note also that only four of the six new Cortaderas Breccia drill holes (DDH-234, DDH-236, DDH-238 and DDH-241) contain complete assay results. Some assay results are pending for the remaining drill holes in the Cortaderas Breccia target area.1Drill hole DDH-230 was reported in a previous Silver Standard news release (July 25, 2012).2Historic underground mining exploited the high-grade Oploca mineralization for less than 100 meters of strike length and about 75 meters vertically.Table 1: Mineralized intervals from drill holesHole No.Target AreaFrom (m)To (m)Length (m)Ag g/tZn %DDH-230Cortaderas Breccia188.00214.0026.0084.84.6297.00330.0033.00118.46.2338.00354.0016.0056.94.3380.80404.5623.761,763.74.9435.92490.0054.08798.315.6DDH-234Cortaderas Brecciansi3nsi3DDH-235Portal Drilling Target384.00388.384.38280.711.6DDH-236Cortaderas Breccia107.00112.003.04124.912.2DDH-237Portal Drilling Target523.50530.006.50425.51.6DDH-238Cortaderas Breccia190.86215.6024.74135.03.5232.00244.0012.0081.03.3257.74279.5221.7857.95.0286.35292.005.65112.95.9300.30323.4523.1541.14.0343.00370.0027.00201.89.8388.00412.0024.0056.14.1DDH-239Portal Drilling Target310.55326.6816.1361.24.4561.38567.005.6258.16.8DDH-240Cortaderas Breccia109.00112.803.8074.47.0168.00175.957.9576.87.8DDH-241Cortaderas Breccia183.33188.505.1790.87.6192.87216.5023.63153.95.1291.00455.00164.0097.23.9including411.00455.0044.00220.05.2DDH-242Portal Drilling Targetnsi3nsi3DDH-243Cortaderas Breccia428.00451.2823.38388.09.7DDH-244Oploca Depth Extension331.05331.650.607,600.016.9336.06338.602.54468.82.5363.00365.002.002,280.00.1DDH-245Oploca Depth Extension286.66288.511.8553.09.8297.00298.001.0031.010.1301.37301.760.3939.0>30.0DDH-246Cortaderas Breccia392.00396.004.00671.84.9DDH-247Oploca Depth Extension305.35307.001.65119.07.3317.00320.033.0394.55.9323.00324.001.0050.48.0327.00328.001.002.48.8 Notes:DDH-230 was reported in a previous news release (July 25, 2012). Cortaderas Breccia drill holes are oriented at shallow angles to the inferred plunge orientation of the mineralized breccia body. The mineralized intercepts are not true thicknesses, which are to be determined with follow-up drilling. nsi means "no significant intersections". The assay data presented in Table 1 have not been capped (top-cut). Reported intervals were selected above a 20 g/t Ag cut-off. Complete assay results have been received for drill holes DDH-230, DDH-234, DDH-236, DDH-238 and DDH-241. All other drill holes reported in this table have assays pending.

(Hons.), P.Geo., Senior Geologist, for Silver Standard, is a Qualified Person (QP) as defined in National Instrument 43-101 and has approved the technical information in this news release. Standard drill hole core logging and sampling techniques were used. All drill hole core samples were submitted for preparation and analysis by ALS Chemex at its facilities in Mendoza, Argentina. All samples were analyzed using 'near total' four acid digestion followed by 34 element atomic emission ICP spectroscopy. Over limit Ag (>200 g/t) and Zn (>10%) grades were re-analyzed using a four acid digestion with an AAS finish. Ag grades still over limit (>1,500 g/t) were analyzed by fire assay with a gravimetric finish. Silver Standard employs a rigorous QA/QC program, which includes real-time assay quality monitoring through the frequent insertion of blanks, duplicates, and certified reference standards, the submission of samples to an independent third party laboratory, as well as reviewing laboratory-provided QA/QC data.SOURCE: Silver Standard Resources Inc.Silver Standard's current NI 43-101 Technical Report on the Pirquitas Mine, effective date December 23, 2011, is filed with SEDAR and on the Company's website.
