Premier Gold Mines Limited(“Premier” or “the Company”) is pleased to provide an update of development programs initiated at the Company’s South Arturo Property located in the Carlin Trend of Nevada where construction of both the Phase 1 open pit and the El Nino underground mine have commenced.

The South Arturo Property is a joint venture between Premier (40% ownership) and Barrick Gold Corporation’s wholly‑owned subsidiary of Barrick Gold Exploration Inc. (“Barrick”). Barrick is the operator and processes ore from South Arturo primarily at their Goldstrike facility located 5 kilometres to the south.

Construction of the Phase 1 open pit and the El Nino underground mine have been accelerated resulting in some production expected from both operations later in 2018. Additional work will assess the potential of additional mining opportunities that include a Phase 3 pit and processing of heap leach material from all pits.

“With new mine developments being advanced ahead of schedule at South Arturo, the stage is set for a solid operational future at this strategic property”, stated Ewan Downie, President & CEO. “Work continues on several additional opportunities that could add to reserves and resources and provide for sustained mining operations”.

Phase 1 Open Pit Project

Development of the Phase 1 open pit has begun and will be one of the first open pit mines operated by Barrick that will include autonomous mining equipment. This new technology could provide an opportunity for reduced mining costs and improved safety. Mine development capital in 2018 for Phase 1, on a 100% basis, is currently forecasted for US$17 million and US$90 million for the entire project.

The run-of-mine (“ROM”) material from Phase 1 will be stockpiled, pending a decision on whether to proceed with a processing facility located on the joint venture property. This has the potential to add to future resources and reserves, and subsequent production, at South Arturo.

El Niño Underground Project

The El Nino underground deposit is the down-plunge extension of the Phase 2 pit which was mined in 2016-17. Ground work including backfilling of the Phase 2 pit has been completed and full construction of the El Nino mine will begin in July 2018 with capital costs in 2018 estimated at US$7.4 million on a 100% basis and US$36.4 million for the entire project. Following development of the upper ore zones, underground exploration will be initiated to identify additional mineralization, which remains open at depth and locally along strike.

Additional Opportunities

Work will continue to advance a potential Phase 3 open-pit and additional run-of-mine (ROM) heap leach material that would complement material from Phase 1. Drilling to further define and expand mineralization is currently occurring.

Drilling in 2017 identified mineralization below the current pit design and demonstrated continuity with higher than expected grades in the southern extent of the current resource model. Drilling will primarily follow-up high-grade results from the 2017 program including 117.0 feet grading 0.48 oz/ton Au (35.7 m of 16.54 g/t Au) with 50 feet grading 0.82 oz/ton Au (15.2 m of 28.26 g/t Au) and an additional intercept of 226.5 feet grading 0.09 oz/ton Au (69.0 m of 3.05 g/t Au) in hole ART17-10C – the final hole of the program.

Column leach testing to verify ROM recoveries will be completed in 2018 to validate recovery curves and some additional drilling will be completed to add mineralization in the eastern portion of the Phase 1 pit.

Drilling is also planned for the South Hinge zone, a primary exploration target on the property owing to its proximity to the Phase 2 and Phase 3 pit designs and it’s potential to expand the planned Phase 3 pit. Future exploration will test the East Dee target, located east of the Phase 1 pit which could provide for an additional open pit or underground opportunity.
