Premier Provides Resource Update for Getchell Project

1.465 Million Ounces Au Indicated – 0.465 Million Ounces Au Inferred

THUNDER BAY, Sept. 1, 2020 - Premier Gold Mines Ltd. ("Premier", "the Company") (TSX: PG) (OTCPK: PIRGF) is pleased to provide a resource update for the Getchell Project ("Getchell" or "the Property") that is being acquired by the Company. The Getchell Project hosts both open-pit and underground resources and is strategically located proximal to Nevada Gold Mines' Twin Creeks and Turquoise Ridge mines at the north end of the Battle Mountain Trend at its intersection of the Getchell gold belt in Nevada (see Figure 1 below).

Highlights of the Mineral Resource estimate include:

• Open-Pit:
• • 1.275 Moz Measured & Indicated resources at 0.057 oz/t Au (1.95 g/t)
• Underground:
• • 0.190 Moz Measured & Indicated resources at 0.305 oz/t Au (10.49 g/t)
  • 0.580 Moz Inferred resources at 0.347 oz/t Au (11.90 g/t)

Summary of the Mineral Resources for the Getchell project are summarized in Table 1 (Imperial units) and Table 2 (Metric units), broken down by open-pit (pit-constrained) and underground. They are reported as of 23 July 2020.

"We are pleased to acquire such a high-quality project located in one of the world's most productive gold districts", stated Ewan Downie, President and Chief Executive Officer of Premier. "The grades of both the open-pit and underground deposits rank amongst the highest in North America and our future focus will be to advance both to production. Within our Nevada division, the Getchell Project will become our largest resource, in terms of contained gold resources, and we are confident that it will quickly advance to potentially become our flagship Nevada project."

The gold mineralization at Getchell is located within the Comus Formation which consists of interbedded shale, siltstone and limestone. This formation also hosts the deposits of the mining operations located immediately to the north of the Property.

Several zones of relatively continuous mineralization were defined by historical drilling that had missing original certificates. The decision was then made to exclude them from the current mineral resources. Validation of historical assays in this region with new drilling could confirm these results and may provide additional upside to the project. All the known gold zones on the Property remain open for expansion.

On August 5, 2020, Premier announced that it is contemplating creating a SpinCo including all of Premier's Nevada assets. In the event the Company elects to proceed with the Getchell Property, it is expected to be included in the spin-out transaction.

Premier Gold Mines Ltd. is a gold-producer and respected exploration and development company with a high-quality pipeline of precious metal projects in proven, accessible, and safe mining jurisdictions in Canada, the United States and Mexico.
