Pretium Resources Inc.: Underground Exploration Drilling at Brucejack Extends Mineralization Below the Current Mining Levels and Intercepts High-Grade Gold to the East

VANCOUVER, May 03, 2021 - Pretium Resources Inc. (TSX/NYSE: PVG) ("Pretivm" or the "Company") today announces that underground exploration drilling conducted in 2020 from the 1080 Level, one of the lowest mining levels at the Brucejack Mine, intercepted high-grade gold mineralization at depth and to the east of the Valley of the Kings deposit.

"These results continue to highlight the potential to extend beyond the defined resource and confirm that the Valley of the Kings deposit remains open at depth," said Jacques Perron, President and Chief Executive Officer of Pretivm. "A new extension of gold mineralization was also intercepted immediately to the east of the existing underground infrastructure that could provide easy access for future development. Our follow-up underground resource expansion drill program is currently underway, and we look forward to announcing the next set of drill results."

The 1080 Level resource expansion drill program is separate from the previously disclosed North Block expansion drill program, which intercepted high-grade gold mineralization to the north of current underground infrastructure (see news release dated February 25, 2021). Both programs formed part of the underground resource expansion drill program.

Drilling on the 1080 Level East and 1080 Level West intercepted high-grade gold mineralization up to 200 meters below and 200 meters east of the current Mineral Resource shell. Four intersections assayed above 1,000 grams per tonne gold. Results include 245.9 grams per tonne gold over 7.5 meters, including 1,635 grams per tonne gold and 1,465 grams per tonne silver over 1.0 meter in VU-2421 and 1,400 grams per tonne gold and 1,310 grams per tonne silver over 1.0 meter in VU-2397.

The 1080 Level resource expansion drill program was comprised of 14,009 meters in 59 drill holes, with 4 drill fans completed in the 1080 Level East and 2 drill fans completed in the 1080 Level West. Drilling tested an area to the east and west of where Pretivm is currently mining on the level.

1080 Level Drilling - Assay Results

Drilling in the 1080 Level East intersected visible gold mineralization in breccias along the Bridge Zone Porphyry contact and in narrow quartz-carbonate veins within the Bridge Zone Porphyry. This is a new area of gold mineralization that presents the down dip extension of domains in higher levels of the mine. Drilling in the 1080 Level West identified high-grade gold mineralization in the footwall of the Domain 20 normal fault and the down dip extension of the Domain 20 quartz stockwork.

In 2021, the 1080 Level resource expansion drill program will focus on infilling between the initial drill fans, particularly on the lower extents of the Brucejack Fault in the West and the visible gold mineralization associated with the Bridge Zone Porphyry contact in the East. Drilling is currently underway, and assay results are pending.

Significant drill results are shown below:

• Hole VU-2355 intersected 303.6 grams per tonne gold over 5.0 meters, including 1,380 grams per tonne gold and 373 grams per tonne silver over 1.0 meters.
• Hole VU-2380 intersected 96.9 grams per tonne gold over 5.3 meters, including 399 grams per tonne gold over 1.0 meters.
• Hole VU-2421 intersected 245.9 grams per tonne gold over 7.5 meters, including 1,635 grams per tonne gold and 1,465 grams per tonne silver over 1.0 meters.
• Hole VU-2422 intersected 16.7 grams per tonne gold over 28.0 meters, including 381 grams per tonne gold over 1.0 meters.
• Hole VU-2383 intersected 1,555 grams per tonne gold and 1,665 grams per tonne silver over 1.0 meters.
• Hole VU-2397 intersected 1,400 grams per tonne gold and 1,310 grams per tonne silver over 1.0 meters.
• Hole VU-2398 intersected 15.7 grams per tonne gold over 7.5 meters.
