Premier Gold Mines Limited (TSX: PG) is pleased to announce an exploration update from an ongoing 42,000 m exploration and delineation core drilling program at the Company’s 100%-owned Mercedes Mine, located in the State of Sonora, Mexico. Multiple new intercepts at the Lupita zone indicate the potential to extend the horizon by up to 600 metres to the west.

Highlights of this program include:

• New mineralized veins confirmed at San Martin opening the area 600 m to the west of the Lupita deposit with high potential for future discoveries (Figure 1)
• San Martin drilling returned multiple intercepts including 7.2 m of 4.64 g/t Au & 30.45 g/t Ag and 1.4 m of 5.56 g/t Au & 37.66 g/t Ag (L19-400D and L19-396D)
• Ongoing delineation program at Lupita including intercepts of 3.9 m of 10.30 g/t Au & 88.25 g/t Ag and 1.5 m of 23.90 g/t Au & 71.15 g/t Ag (L19-403D and L19-408 D)
• Exploration to be activated at La Mesa, which represents the geological extension of the adjacent Santa Gertrudis Property, where Agnico Eagles Mines Ltd is having exploration success (See Figure 3)

“Our Lupita delineation and exploration program is emerging as an important success story at Mercedes,” commented Stephen McGibbon, Executive Vice-President. “We are concurrently activating teams in under-explored areas on the property in an effort to discover new deposits”.

Lupita Extension and San Martin Success

Mercedes is an underground gold and silver mine, with production to date (2011-2018) of 687,000 recovered ounces of gold, that exploits quartz veins and quartz-carbonate stockworks within a low-sulphidation epithermal system (Figure 1). The Lupita-Diluvio basin, located 4 km northeast of the main trend, is attractive for future discoveries. As at December 31, 2018, the Lupita deposit carried a mineral reserve of 329 kt @ 4.42 g/t Au for 47 koz of gold and is located immediately west of the Diluvio deposit. The Lupita Vein outcrops on surface for 1,300 m, has an average width of 3 m, and locally extends down dip up to 450 m. Initial exploration drilling to the west and east of Lupita at both San Martin and Margarita have recently discovered mineralized veins along the Lupita fault (Figure 2). These areas are 3 km apart and remain open further to the east and north.

The Lupita Extension drill program continues to expand 2018 resource mineralization by demonstrating the continuity of the vein to the west (Figure 1). Assay results presented in Table 1 include those received since the initial reported results on May 14, 2019, with grades ranging from 3.57 g/t Au over 1.8 m at the periphery to 10.30 g/t Au over 3.9 m. A Phase 2 infill drill program of 6,000 m is currently underway to support the creation of Indicated mineral resources.

Drilling to test the continuity of the Lupita vein 600 m to the west at the San Martin area (Figures 1 & 2) intercepted 1.5 m of 5.56 g/t Au (L19-396D) in the first hole and up to7.5 m of 4.64 g/t Au (L19-400D). Results from this initial program, planned with a wide spaced drilling, are presented in Table 1.

Margarita Exploration

In addition, the Lupita vein is being tested 1.2 km further to the east at Margarita (Figure 2). The area is marked by the projected trend of outcropping veins to the north. The first drill hole testing the Margarita area intercepted 1.3 m of 2.98 g/t Au & 61.93 g/t Ag (L19-395D), warranting further drilling. New discoveries at San Martin and Margarita demonstrate the potential of the Lupita-Diluvio basin which remains largely untested to date. The Company is expanding and accelerating its evaluation of this emerging corridor.

La Mesa Area Exploration

The La Mesa area, located 24 km NE of the main Mercedes Mine, is host to the same stratigraphy that hosts the Santa Gertrudis property deposits owned by Agnico Eagle Mines Ltd. These geological structures extend onto the La Mesa area as shown in Figure 3. 2019 work by Premier will focus on collecting baseline information expected to include mapping, soil sampling, litho-geochemistry and potentially geophysics to better understand the potential of this area.
