Over 45,000 Metres Drilled During the Year

PREMIER GOLD MINES LIMITED (“Premier” or “The Company”) (TSX:PG) is pleased to provide an exploration update of the Company’s 100%- owned Mercedes Mine in the State of Sonora, Mexico. The 2017 exploration program focused on the expansion of potential high-grade, near-infrastructure targets that may be upgraded to resources. Results of the 45,000 metre program of surface and underground drilling will be included in an updated estimate of the resources and reserves, expected in Q1-2018.

Highlights of recent results include:

  • 69.50 g/t Au and 111.78 g/t Ag across 12.2 m in hole UG-BR17-007 at Barrancas.
  • 70.75 g/t Au and 45.16 g/t Ag across 6.0 m in hole R17-169D near surface at Rey de Oro.
  • 22.86 g/t Au and 73.11 g/t Ag across 15.25 m in hole UG-BR17-026 at Barrancas.
  • 84.85 g/t Au and 81.50 g/t Ag across 2.3 m at Brecha Hill in hole UG-BH17-035 testing vein extensions and parallel veins.
  • 13.68 g/t Au and 132.14 g/t Ag across 7.65 m at Casa Blanca in hole MUG17-152D testing vein extensions.

The primary target areas (see Figure 1) included 1) the main Mercedes/Barrancas/Lagunas mine trend; 2) Lupita/Diluvio; 3) open pit and underground targets at Rey de Oro; and 4) new potential vein trends on the property beneath post-mineral cover that had not been previously tested.

A total of 349 core holes were drilled during the year to test for potential extensions of known vein systems and also new mineralized horizons.

Mercedes Mine Trend

Since the mid-year exploration update (June 21, 2017 press release), drilling focused on areas with the highest potential for resource and reserve expansion. This included the Mercedes mine trend, near‑development opportunities at Barrancas, Brecha Hill, Lagunas, Corona de Oro and Casa Blanca (see Table 1 and Figure 2 for highlighted results to-date).

Diluvio-Lupita Target Area

Work at Diluvio-Lupita included surface and underground drilling and an exploration drift to access and bulk sample the Diluvio deposit from the mine workings at Lupita. Table 2 highlights some of the recent drill results and Figure 3 exhibits a cross section of hole L17-337D.

Mineralization at Diluvio-Lupita is distinct from other Mercedes deposits as it occurs in veins along a major fault that can expand into wider mineable vein stockwork systems. Two areas of stockwork mineralization have been identified to-date with Diluvio West interpreted as a faulted offset of the main Diluvio deposit. Recent drill results at Diluvio West display good grades and continuity.

Rey de Oro Target

Recent drilling at Rey de Oro targeted an open-pitable deposit’ focused primarily on the near-surface portion of this vein system with limited deeper drilling to potentially expand underground resources. Table 3 highlights recent drill results from Rey de Oro and Figure 4 provides a cross sectional view of hole R17-169D along with the outline of the resource constrained pit shell.

Generative Targets

The newly discovered Axis vein, 1.5 kilometers south of the main Mercedes vein system, will be a priority drill target in 2018. This wide vein is part of a strong and possibly parallel vein system to Mercedes that was discovered in 2017 by testing below surface. Only one hole has cut the vein system and exhibits wide low-grade gold and silver mineralization. Drilling in early 2018 is designed to vector towards potential higher grade mineralization.

Several other new target areas on the Mercedes property have been identified and will tested systematically in 2018. Geophysical surveys will be conducted prior to drilling in these areas including other Diluvio-style vein stockwork bodies and covered areas between the main Mercedes vein system and Diluvio.
