Premier Expands High-Grade at Mercedes Mine

Drilling Intersects 8.9 m of 9.41 g/t Au & 34.15 g/t Ag at Lupita Extension

THUNDER BAY, Nov. 21, 2019 - Premier Gold Mines Ltd. (TSX:PG) (OTCPK: PIRGF) ("Premier", "the Company") is pleased to announce an update on its 42,000m exploration and delineation core drilling program at the Company's 100%-owned Mercedes Mine, located in the State of Sonora, Mexico. The 2019 drilling campaign is currently focused on delineating new mineral resources in the Lupita Extension area as well as confirming potentially important discoveries at San Martin and Neo (See Figure 1, Table 1). Highlights from October drilling include:

• San Martin exploration drilling expands high grade zone with:
  
• • 1.4 m of 15.80 g/t Au & 69.00 g/t Ag (L19-457D)
  • 4.6 m of 10.03 g/t Au & 57.65 g/t Ag (L19-496D)
    
    
• Ongoing delineation program at Lupita Extension - highlights:
  
• • 8.9 m of 9.41 g/t Au & 34.15 g/t Ag (L19-488D)
  • 3.6 m of 7.96 g/t Au & 31.69 g/t Ag (L19-480D)

"Our Lupita Extension and San Martin drill program has emerged as an important contributor to the future of Mercedes," commented Stephen McGibbon, Executive Vice-President. "With true widths approaching 3 m and grades well in excess of 2019 production grades, each new result is quickly adding to the value of this operation."

Lupita Extension

The Lupita discovery outcrop hosts a 3 m wide silicified vein of typical low-sulphidation epithermal textures and diagnostic green quartz. The Lupita Extension drill program was designed to expand the Lupita resource to the west. After a successful Phase 1 program of 18 drill holes with a 60 m spacing, Phase 2 started in May 2019 on a 30 m grid, aiming to create indicated mineral resource for the year end.

The Phase 2 drill program at Lupita Extension continues to delineate high grade areas and successfully expand mineralization 300 m to the west, where it remains open for expansion. The delineation program completed a total of 87 drillholes, of which 17 still have assays pending.

Based on drilling to-date, the average true width of Lupita Extension is approximately 2.9 m grading 5.56 g/t Au. Minimum mining widths in the Lupita area in 2020 are expected to be reduced from 4 m to 3 m, minimizing dilution in future mining at Lupita Extension. Development to access the Lupita Extension, which is displaying grades well in excess of the current reserve grade at Mercedes, is planned for H1-2020.

San Martin

San Martin is a target located 600 m to the west of Lupita, discovered with an intercept of 1.5 m of 5.56 g/t Au (L19-396D) in the first hole in May 2019. Additional drilling (10 drillholes) suggest an average true width of approximately 3.2 m grading 6.95 g/t Au. The two new intercepts recently drilled at San Martin continue to expand high grade mineralization with 1.4 m of 15.80 g/t Au & 69.00 g/t Ag in L19-457D and 4.6 m of 10.3 g/t Au & 57.65 g/t Ag in L19-496D.

Although these new results increase the high-grade discovery of San Martin, management believes the distribution and tenor of grade at San Martin may be similar to Lupita Extension. More delineation is planned in 2020 with the intent to upgrade mineralization to an Indicated mineral resource. Given a spacing of less than 60 m of drilling at San Martin during 2019, a portion of the mineralization will warrant inclusion into mineral resources at year end.
