Silver Standard Discovers Higher Grade Mineralized Area at the Marigold Mine

VANCOUVER, Sept. 18, 2015 /CNW/ - Silver Standard Resources Inc. (NASDAQ: SSRI) (TSX: SSO) ("Silver Standard") announces the discovery of a new gold mineralized area at its Marigold mine ("Marigold") in Nevada, U.S. referred to as the HideOut area.

Selected Drillhole Highlights:

Mineral Resources development drilling identified a new higher grade mineralized center known as the HideOut area, located southeast of the 8 South pit.

  • Drillhole MR-6170 intersected 2.47 g/t gold over 76.2 metres from 152.4 metres below surface, including 5.44 g/t gold over 30.5 metres from 161.5 metres below surface.

  • Drillhole MR-6149 intersected 2.05 g/t gold over 33.5 metres from 175.3 metres below surface, including 4.31 g/t gold over 13.7 metres from 189.0 metres below surface.

  • Drillhole MR-6159 intersected 1.91 g/t gold over 54.9 metres from 121.9 metres below surface, including 2.91 g/t gold over 32.0 metres from 128.0 metres below surface.

 

Paul Benson, President and CEO said, "The discovery of another mineralized area with intercepts above average reserve grade, related to our recent 8SX and 8D discoveries, continues to build exploration upside at Marigold. Our exploration team is unlocking value with an ultimate goal of mine life extension and driving better margins through these higher grade discoveries."

Mineral Resource Development Drilling

The 2015 Mineral Resources development program at Marigold is targeting the discovery and development of gold mineralization proximal to the open pits. The primary objective of the program is to upgrade Inferred Mineral Resources to Indicated Mineral Resources and to convert Mineral Resources to Mineral Reserves. In addition to the previously reported discoveries of the 8 South pit extension ("8SX") area and the 8D area, recent exploration drilling at Marigold identified a new mineralized center outside the current resource envelope called the HideOut area, with intercepted grades higher than the Mineral Reserves cut-off grades. HideOut is located 800 metres south of the 8SX area and 60 metres north of the ultimate pit limit. A total of 3,860 metres in 15 reverse circulation drillholes were completed at the HideOut area in the third quarter of 2015.

The HideOut gold mineralization is hosted by Antler Formation carbonate rocks, is oxidized and therefore recoverable using the heap leach process at Marigold. The HideOut area has not previously been drilled and is open to the north into the 8SX area. The mineralized centers at the HideOut and 8SX areas are covered by rock stockpiles. Assay results through these rock stockpiles indicate gold grades above the Mineral Reserves cut-off grades. These rock stockpiles can be considered as low grade mineralization. The rock stockpile assay intervals above the HideOut bedrock mineralized zones are included in all down hole lengths.

Refer to Figure 1 for the location of drillhole collars. Selected results from eight drillholes with higher-grade gold intercepts are included in Table 1. A list of drillhole collar details is included in Table 2.

Next Steps

The HideOut results will be included in an updated Mineral Resources estimate for Marigold reported in our annual 2015 Mineral Resources and Mineral Reserves statement to be published in the first quarter of 2016.

Sampling and Analytical Procedures

All drill samples in respect of the program were sent for processing and analysis to the offices of American Assay Laboratories, Inc. ("AAL") in Sparks, Nevada which is an ISO 17025 accredited laboratory independent from Silver Standard. Fire assay was completed on a 30 gram sample (AAL method code FA-PB30-ICP) with an Inductively Coupled Plasma ("ICP") finish after a two acid digestion.  Samples with assay results greater than 10 g/t were fire assayed on a 30 gram sample (AAL method code Grav Au30) with a gravimetric finish. We employ a rigorous Quality Assurance/Quality Control ("QA/QC") program, which includes real-time assay quality monitoring through the regular insertion of blanks, duplicates, and certified reference material, as well as reviewing laboratory-provided QA/QC data.

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 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. In addition, the SEC's disclosure standards normally do not permit the inclusion of information concerning "Measured Mineral Resources," "Indicated Mineral Resources" or "Inferred Mineral Resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. U.S. investors should understand that "Inferred Mineral Resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Moreover, the requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported by us in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
