THUNDER BAY, ON, May 7, 2019

Delineation program intersects 31.0 m of 4.96 g/t Au & 71.06 g/t Ag

THUNDER BAY, ON, May 7, 2019 /CNW/ - Premier Gold Mines Limited (TSX: PG) ("Premier", "the Company") is pleased to announce high-grade intercepts from initial underground drilling at the east margin of the Marianas Zone, one of the primary exploration targets at the Company's 100%-owned Mercedes Mine, located in the State of Sonora, Mexico.

Highlights of this delineation drill program include:

• 31.0 m of 4.96 g/t Au & 71.06 g/t Ag including 3.1 m of 25.65 g/t Au & 171.30 g/t Ag (UG-MR19-011)
• 20.5 m of 4.51 g/t Au & 64.09 g/t Ag including 3.8 m of 11.04 g/t Au & 94.09 g/t Ag (UG-MR19-007)
• 3.5 m of 7.29 g/t Au & 8.25 g/t Ag (UG-MR19-010)

"Initial drilling confirms our belief that Marianas will be important to the future of Mercedes", commented Stephen McGibbon, Executive Vice-President. "The drill program is in its very early stages, testing the margins of Marianas from new ramp development. We expect stronger and more consistent results as the drilling progresses toward the core of the Marianas resource later in 2019". 

Marianas

The Marianas Zone comprises the down-plunge extension of the main Mercedes mine trend (Figure 1). Previous surface drilling suggests Marianas has the potential to host economic mineralization of higher than the current reserve grade. It is the Company's goal to convert a portion of Marianas mineral resources to mineral reserves with a delineation drill program during the balance of 2019. Ore development could commence in 2020.

Mercedes is an underground gold and silver mine that exploits quartz veins and quartz-carbonate stockworks in a low sulphidation epithermal system at an extraction rate approaching 2,000 tonnes per day. The main Mercedes mine trend is host to a series of high grade sub-vertical quartz veins that strike in a northwesterly direction. It represents the property's most substantial producing area with total past-production of some 687,000 recovered ounces from 2011 through 2018. Premier has been extending the mine's production ramp to support the delineation and possible expansion of mineral resources into the "Indicated" category with more than 13,000 m of surface and underground drilling planned in 2019. Table 1 provides highlights of significant intercepts from 11 holes completed at the margin of the Marianas East area, away from the core of the mineral resource. Locally, the grade and width of mineralization is exceeding expectations with intercepts of up to 31.0 m of true width grading 4.96 g/t Au and 71.06 g/t Ag in hole MR-UG-011 from drill bay #1 (Figure 2). Importantly, this mineralization is located within 100 m of the main ramp.

Delineation Program

At the end of 2018, mineral resources in the Marianas area stood at 21 kt at 18.39 g/t Au for 13,000 ounces of gold (Indicated) and 645 kt at 4.46 g/t Au for 92,000 ounces of gold (Inferred). The grade x thickness image profiles the current distribution of drilling planned in 2019 and beyond (Figure 2). The delineation program started at the beginning of the year with the development of the ramp west to the Lagunas deposit. The current results are from drill bays 1 & 2, intersecting the Marianas East vein which will be the focus of the 2019 underground program. Delineation from surface is planned on the north side of the deposit, mainly within the Marianas West vein. The objective from the 2019 campaign is to convert half of the inferred mineral resources in this area. In addition to Marianas, the Mercedes team is targeting the Lupita, Diluvio and Rey de Oro areas in 2019 to offset mining depletion and focus on mineral resource growth.
