Development Activities At Marigold Mine

 

VANCOUVER, BC - Silver Standard Resources Inc. reported an exploration update for first quarter Mineral Resource development activities at its Marigold mine in Nevada. 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; 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."

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 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 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.

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.

Silver Standard undertook the Assay Program with the objective of identifying low-grade ore that was not included in the existing Mineral Reserves. In 2015, the company assayed a total of 97,950 samples from within the planned production areas through 2019 and anticipates 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.
