SILVER STANDARD PROVIDES FIRST QUARTER 2017 CORPORATE

EXPLORATION UPDATE

VANCOUVER, B.C. -- Silver Standard Resources Inc. (NASDAQ: SSRI) (TSX: SSO) (“Silver

Standard”) provides an update on its exploration ac tivities at its Marigold mine in Nevada, U.S.

and Seabee Gold Operation in Saskatchewan, Canad a, including selected drillhole results from

the first quarter of 2017 and, previously unreleased results, from the fourth quarter of 2016.

Highlights:

 Highlighted drill results at the Marigold mine include:

 At the Mackay pit, drillhole MRA6434 intersected 1.09 g/t gold over 106.7 meters;

 At Valmy, drillhole MRA6368 intersected 0.57 g/t gold over 45.7 meters; and

 At Battle Cry, drillhole MRA6384 intersected 0.51 g/t gold over 91.4 meters.

 Highlighted drill results at the Seabee Gold Operation include:

 At Santoy 8A, drillhole SUG-17-902 intersecte d 21.89 g/t gold over 3.0 meters of true

width;

 At Santoy Gap, drillhole SUG-17-015 intersected uncut grade of 1,004.74 g/t gold over 1.6

meters true width, including an intersected in terval of 3,887.8 g/t gold over 0.4 meters

true width; and

 At Santoy, on a new target Gap HW, drillhole JOY-16-749 intersected 8.20 g/t gold over

9.9 meters of true width.

Paul Benson, President and CEO said, “Our exploration programs at Marigold and Seabee

continue to deliver positive results that demonstrate resource growth potential. We were pleased

with the significant increase in Mineral Reserves at both operations at the end of 2016 and are

confident that our exploration activities this ye ar, supported by strong in-house expertise and

expenditures of $5 million at each mine, will once again have a positive impact on our year-end

Mineral Reserves. Brownfields exploration is a key aspect of our strategy to extend the life of our

operations and create long term shareholder value.”

Exploration activities during the first quarter of 2017 focused on the conversion of Mineral

Resources to Mineral Reserves in areas proximal to the 2016 Mineral Reserves. During the quarter

we completed 10,255 meters of reverse circulation drilling in 44 drillholes on four targets in close

proximity to the existing pits. The most notable results include drillhole MRA6434 located in the

center of the Mackay pit, which intersected 1.09 g/t gold over 106.7 meters from 43 meters below

surface, as shown in Figures 1 and 2. Further drilling will be conducted in these four target areas

during the remainder of the year.

In the fourth quarter of 2016, we continued drillin g on targets at Valmy and Battle Cry with the

objective of increasing Mineral Resources. Result s received in the first quarter of 2017 from this

drill program have increased the mi neralized volume laterally and at depth compared to our

Mineral Resource model at both Valmy and Battle Cry.

At Valmy, the mineralized structural trend co ntinues approximately 400 meters beyond the

south-east corner of the historic mining. Th e best results include drillhole MRA6368, which

intersected 0.57 g/t gold over 45.7 meters from 194 meters below surface, followed by drillhole

MR6379, located 160 meters away, that intersected 0.5 g/t gold over 85.3 meters, as shown in

Figure 3. Such results demonstrate the potentia l to increase and convert Mineral Resources at

Valmy.

The Battle Cry area is located 400 meters south of the Basalt pit and represents a new area that

contributed to 2016 Indicated Mineral Resource s. The most notable result was from drillhole

MRA6384, which intersected 0.51 g/t gold over 91. 4 meters from 69 meters below surface. This

drillhole is outside of our 2016 Mineral Resource model and demonstrates the potential to

increase Mineral Resources for conversion to Mineral Reserves in this area.

The positive drill results received to date from this Marigold drill program warrant further

drilling, which is currently underway. Table 1 lists selected drill results from the first quarter of

2017 and the fourth quarter of 2016, while Table 2 provides the collar coordinates and drillhole

lengths.

Seabee Gold Operation, Canada

In the first quarter of 2017, we completed 16,267 meters of underground drilling and 11,394

meters of surface drilling in 42 and 24 drillholes, respectively, with the goals to discover, increase

and convert Mineral Resources.

Our underground drill program for the first quarter of 2017 focused on three targets, including

Santoy Gap, Santoy 8A vein and the new Santoy Gap Hanging Wall (“Gap HW”), with positive

results at all three areas.

Drilling at Santoy Gap aims to increase or upgr ade Inferred Mineral Resources, with the most

notable result being drillhole SUG-17-015, which intersected an uncut grade of 1004.74 g/t gold

over 1.6 meters true width, including 3,887.8 g/t go ld over 0.4 meters true width. This drillhole

is located in an area outside current Mineral Resources but is within 25 meters of existing

mineralization. Six drillholes in this area have an average grade of 11.8 g/t gold over a true width

of 2.3 meters.

At Santoy 8, drilling was focused on upgrading existing Mineral Resources at the Santoy 8A vein,

with the most notable result from drillhole SUG-17-902, which intersected 21.89 g/t gold over 3.0

meters on the lower zone of Inferred Mineral Resources. Also on the Santoy 8A vein, we received

results from drillhole JOY-16-751, which assayed 9. 11 g/t gold over 9.5 meters. This drillhole is

located between two areas of Inferred Mineral Re sources and has the potential to re-establish

continuity between these two zones.

At Gap HW, surface drilling designed to confirm th e new target returned an assay of 8.20 g/t

gold over 9.9 meters in hole JOY-16-749. Gap HW is mineralization that is associated with a dyke-

like mass of granodiorite located almost 200 meters in the hangingwall of the Gap shear zone. If

Mineral Resources are confirmed here, they would offer increased operational flexibility.

Further drilling at all three targ ets is underway to determine the continuity of the identified

mineralization. The drill results from our firs t quarter underground program are shown on the

longitudinal section in Figure 4. Table 3 lists highlighted drill results at the Seabee Gold Operation

for the fourth quarter of 2016 and first quarter of 2017.

Surface exploration drilling in the first quarter focused on three areas including Porky Main, Carr

and Herb, with positive results identified at the former two areas. At Porky Main, three drillholes

have been completed to explore the down dip region up to 350 meters below the existing Mineral

Resources. Results are still pending, but dr illhole PKY-17-049 intersected quartz veining and

arsenopyrite with visible gold. Drilling at th e Carr target has define d a linear mineralized

structure with alteration and mineralization similar to Santoy Gap. Thus far, nine holes have been

completed with analytical results received fo r drillhole CAR-17-001, which intersected 3.09 g/t

gold over 1.15 meters. Due to these encouraging results, additional exploration drilling has been

planned for the first half of 2017 at both areas to define additional Inferred Mineral Resources.

At the Fisher project, where we hold an option, planning is underway for exploration activities

in the second half of 2017. We have compiled ava ilable data and prioritized field targets, which

will be used to select drill targets. Material s and equipment for the exploration camp, field

activities and drilling at the Fisher project were delivered via ice roads during the first quarter of

2017.

Next Steps

At the Marigold mine, 2017 exploration objectives are to replace depleted Mineral Reserves

through conversion of existing Mineral Resour ces and to discover new Mineral Resources.

Conversion targets exist at the East Basalt, Ba ttle Cry, Crossfire, and Hollow Point areas and

within the Mackay pit.

At the Seabee Gold Operation, our underground 2017 exploration plan is for the completion of

up to 60,000 meters of drilling to upgrade existing Mineral Resources and to discover additional

Inferred Mineral Resources at Santoy Gap, Santoy 8 and the Seabee mine. At the Seabee mine, we

have allocated approximately 30% of underground drilling for testing of targets to maximize

Mineral Resource potential at the mine as we develop our longer term strategy for this historically

productive area. Our surface drill programs at the Seabee Gold Operation are expected to

complete approximately 28,500 meters on up to nine district targets.
