Premier Gold Begins Underground Drilling at Marianas / Mercedes

THUNDER BAY, Oct. 23, 2018 - Premier Gold Mines Ltd. ("Premier" or "The Company") (TSX:PG) is pleased to announce the commencement of underground exploration drilling at the Marianas Zone, one of the primary exploration targets at the Company's 100%-owned Mercedes Mine, located in the State of Sonora, Mexico. 

The Marianas Zone was discovered by surface drilling and represents the down-plunge extension of the main Mercedes mine trend (see Figure 1).  Based on previous intercepts, Marianas appears to have the potential to host economic mineralization of higher than the current reserve grade.  It is the Company's goal to convert Marianas mineral resources to mineral reserves with a delineation drill program over the balance of 2018 and 2019.  With success, mining at Marianas could begin in the second half of 2019.

The mine operations team is constructing a decline from the Lagunas mine workings for the purposes of definition drilling followed by mining (see Figure 2).  The multi-year underground drill program will also consist of step-out drilling as the deposit remains open for expansion.  Success at Marianas could result in a significant extension to the mine life at Mercedes.  Supporting the development of Marianas, as well as other future mining areas in the Life of Mine plan, the Company is in the final stages of constructing a new tailings facility, a project that is expected to be completed during the fourth quarter of 2018.

 In addition to the program at Marianas, drilling continues on several other priority target areas with the goal of replacing reserves and adding to resources.  The 2018 program is expected to include more than 40,000 meters of both surface and underground drilling, testing for extensions to the known vein systems in addition to exploring for new mineralized horizons located in close proximity to existing mine workings.

Premier Gold Mines Limited is a gold-producer with a high-quality pipeline of precious metal projects in proven, accessible and safe mining jurisdictions in Canada, the United States, and Mexico. The goal is to evolve into a low-cost, mid-tier gold producer through its two producing mines and the development of its Hardrock Project in Ontario (Greenstone Gold JV) and McCoy-Cove Property in Nevada and where permitting and pre-construction initiatives are well-advanced.
