Premier Replaces Eighteen Months of Mined Gold Reserves at Mercedes

Increases Measured and Indicated Mineral Resources by 34% and Inferred by 23%

THUNDER BAY, ON, March 26, 2018 /CNW/ - PREMIER GOLD MINES LIMITED ("Premier" or "The Company") (TSX:PG) is pleased to provide an update of mineral reserves and mineral resources ("MRMR") effective December 31, 2017 at the Company's 100%-owned Mercedes Mine in the State of Sonora, Mexico. The estimate, completed by the Mercedes Mine personnel will be documented in an independent technical report completed on behalf of Premier by Roscoe Postle Associates Inc. (RPA).

Highlights from the December 31, 2017 MRMR statements include:

• Mineral reserves of 417,000 ozs gold at 3.94 g/t net of mining depletion since June 30, 2016
• A 34% increase in measured and indicated resource to 511,000 ounces at 4.32 g/t
• A 23% increase in inferred mineral resources to 220,000 ozs gold at 4.2 g/t

Mercedes is an established 2,000-tpd underground mining operation on a 69,000-hectare property that hosts multiple low‑sulphidation, epithermal gold and silver deposits made up of veins, stockworks and breccia zones emplaced within structurally-controlled andesite-filled basins. Results reflect organic growth in MRMR through successful exploration as well as technical de-risking of current mine areas.

"Replacing reserves and expanding resources net of depletion, since acquisition, demonstrates our ability to extend the mine life at Mercedes." stated Ewan Downie, President & CEO. "Improved reserve and resource visibility will continue to be a top priority as we optimize our long-term goal of safe, low-cost production.  A priority for 2018-19 will be to complete underground infrastructure to support definition drilling of the high-grade Marianas Zone in order to move the deposit into the future mine plan."
