VANCOUVER, British Columbia, May 9, 2016 /PRNewswire/ -- Silver Standard Resources Inc. (NASDAQ: SSRI) (TSX: SSO) ("Silver Standard") provides an exploration update for first quarter Mineral Resource development activities at its Marigold mine ("Marigold") in Nevada, U.S.

Highlights:

• Resource development drilling in the Mackay North area continues to confirm the continuity of mineralization with higher grades and consistent widths expected to convert Mineral Resources to Mineral Reserves.  Select results included:
  • At Terry Zone North, drillhole MR6188 intersected 0.88 g/t gold over 74.7 meters from 118.9 meters below surface; and
  • At HideOut, drillhole MR6186 intersected 1.30 g/t gold over 29.0 meters from 94.5 meters below surface.
• Valmy project permits are expected in May 2016 and will enable exploration drilling to begin by the end of the second quarter of 2016.

Paul Benson, President and CEO said, "Our exploration team continues to unlock additional value at Marigold. The ultimate goal of our work is mine life extension and driving better margins through these higher-grade discoveries and better understanding of the resource model."

Mineral Resource Development Drilling at Mackay North

The most recent phase of the Mackay North Mineral Resources development program consisted of 54 drillholes totaling 11,860 meters and was completed during the first quarter of 2016. Drilling as of quarter-end has continued to confirm the continuity of mineralization with higher grades and consistent widths expected to convert Mineral Resources to Mineral Reserves. 

The objectives of the Mackay North Mineral Resources development program are to add Mineral Resources within the Terry Zone North ("TZN"), convert these Mineral Resources to Mineral Reserves by year-end, add definition to the HideOut deposit and conduct step-out drilling to add Mineral Resources on trend.

Drill results as shown on the cross-section A-A' demonstrate the presence and continuity of higher-grade structures with additional drillhole results pending from the continuing program. The best result from the first quarter drilling program was drillhole MR6188 that intersected 0.88 g/t gold over 74.7 meters, including 4.48 g/t over 10.6 meters. This drilling, combined with our program to re-assay historic samples (the "Assay Program") underway within the TZN area, is expected to convert these Mineral Resources to Mineral Reserves upon the completion of the drilling and Assay Program. The TZN deposit has estimated Indicated Mineral Resources of 220,000 ounces of gold at December 31, 2015.

Resource definition drilling in the HideOut deposit has defined and extended gold mineralization south of the discovery hole (MR6127) drilled in 2015 and north of the current Mackay pit limit. The best result from the first quarter drilling program was drillhole MR6186 that intersected 1.30 g/t gold over 29.0 meters, including 3.30 g/t gold over 9.1 meters. The step out drilling in the Hideout deposit area has extended mineralization northward by an additional 125 meters. This drilling within the HideOut deposit area is expected to increase Mineral Resources upon the completion of the drill program later in 2016. The HideOut deposit has estimated Indicated Mineral Resources of 48,500 ounces of gold at December 31, 2015.

Figure 1 shows the location of the 2016 drillhole collars. Figures 2 and 3 are cross-sections through the TZN and HideOut areas, respectively. Results from this quarter's drillholes are included in Table 1. A list of drillhole collar coordinates is included in Table 2. The Mackay North area exploration and development program results will be included in an updated Mineral Resources estimate for Marigold in the fourth quarter of 2016 and reported in our annual 2016 Mineral Resources and Mineral Reserves statement to be published in the first quarter of 2017.

Valmy Property

Valmy property permits are expected to be received in May 2016, which will enable exploration drilling to begin in the second quarter of 2016. The objective of the 2016 Valmy drill program is to convert Mineral Resources to Mineral Reserves. During the quarter, geologic interpretation from historical data was conducted and target areas have been identified. The Valmy property has estimated Inferred Mineral Resources of 300,000 ounces of gold at December 31, 2015.

Assay Program

During 2015, we undertook the Assay Program with the objective of identifying low-grade ore that was not included in the existing Mineral Reserves. In 2015, we assayed a total of 97,950 samples from within the planned production areas through 2019.  We anticipate re-assaying up to 60,000 samples in 2016, which is sufficient to cover the remainder of the current mine plan. The Assay Program has allowed better spatial definition of the lower grade portions of the ore body.

During the first quarter of 2016 we have assayed 25,504 samples. Thus far, results from the Assay Program carried out in 2016 are broadly in line with results achieved in 2015. The Assay Program will be completed by the end of the second quarter 2016 having assayed all samples within the current life of mine plan and those within the TZN area.

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 SEC 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.
