Premier Extends High Grade Mineralization at McCoy-Cove

Download Press Release


PREMIER GOLD MINES LIMITED (TSX:PG) (“Premier”, “the Company”) is pleased to announce additional positive drill results that indicate further extension of the high grade CSD Gap zone at the Company’s 100%-owned McCoy-Cove Gold Project, situated along the Battle Mountain-Eureka Trend in Nevada. The results from the ongoing 15,000 metre drill program listed in this release all occur between the Helen Zone and the historic Cove South Deep (CSD) underground zone, and continue to exhibit high-grade mineralization over substantial widths.

The focus of the ongoing drill program is to delineate and expand the zone of the Carlin-style gold and silver system within the CSD Gap, as shown in Figure 1 and Table 1 below. Results from drill-hole PG16-12, a 100m step-out along strike from hole PG16-10 extends high grade mineralization towards the Helen Zone and remains open for expansion along strike to the northwest. Upon completion of the program Premier plans to commence a property-wide mineral resource estimate and a Preliminary Economic Assessment.


Highlights of the recent results include:

  • PG16-12: 28.64 g/t Au and 7.37 g/t Ag over 12.0m at 599.7m (or 0.84 oz/t Au and 0.21 oz/t Ag over 39.5 ft.)
    and 27.71 g/t Au and 12.95 g/t Ag over 6.9m at 627.1m (or 0.81 oz/t Au and 0.38 oz/t Ag over 22.5 ft.)
  • PG16-14: 6.16 g/t Au and 0.86 g/t Ag over 10.8m at 653.9m (or 0.18 oz/t Au and 0.03 oz/t Ag over 35.5 ft.)
    including 9.48 g/t Au and 0.45 g/t Ag over 3.2m (or 0.0.28 oz/t Au and 0.01 oz/t Ag over 10.5 ft.)
  • PG16-16: 5.31 g/t Au and 1.20 g/t Ag over 32.3m at 551.7m (or 0.15 oz/t Au and 0.04 oz/t Ag over 106 ft.)
    including 8.55 g/t Au and 2.41 g/t Ag over 7.6m ( or 0.25 oz/t Au and 0.07 oz/t Ag over 25.0 ft.)
  • PG14-18: 5.56 g/t Au and 11.93 g/t Ag over 6.0m (or 0.16 oz/t Au and 0.35 oz/t Ag over 19.8 ft.) at 571.1m.
    This hole was drilled to complete the core tail of a pre-collared hole drilled in 2014

“The 2016 exploration program continues to exceed expectations with PG16-16 further closing the gap with the Helen Zone to the northwest” stated Chad Peters, Nevada Exploration Manager for Premier on the Company’s C-Suite Blog. “We currently have four rigs mobilized at McCoy-Cove with the remainder of 2016 focusing on select Helen and CSD Gap infill and expansion drilling to support the upcoming Q1 2017 resource estimate.”

The Cove geologic model proposes that the most robust gold and silver mineralization in the Helen deposit, the CSD gap and the 2201 Zones are closely associated with the deep-seated Cove thrust fault and altered mafic sills that acted as both primary structural controls and fluid conduits. The 2016 drill results continue to confirm this model as well as highlight multiple, high-grade silver intercepts outside of the defined CSD Gap horizon. These intercepts are directly adjacent to the Cove thrust and the historically untested CT-1 splay which suggests additional potential remains to define high grade gold and silver mineralization outside of the known mineralized horizon. The ongoing drill program will therefore also target mineralization hosted within the hanging wall of the CT-1 splay as a means to further expand the known footprint of the CSD Gap and Helen deposits.

Plan of Operations/2017 Guidance

The Cove-Helen Underground Exploration Plan of Operations (PoO) was approved in 2013 granting Premier the option of pursuing an underground exploratory drill program as well as test mining in the Helen Zone. A supplementary 2016 budget has led Premier to initiate preliminary engineering, dewatering and baseline studies required to advance the underground exploration PoO towards development. Dewatering was an important aspect of historic mine operations at Cove and as a result, the installation of vibrating wire piezometers in select exploration drill holes commenced in Q2 in order to monitor groundwater in the vicinity of the Helen and CSD Gap deposits. Preliminary dewatering simulations of the proposed test mining scenario are now complete and results indicate that the potential dewatering outflow levels for the test mining scenario would fall within the currently permitted PoO. Further optimization and validation of the dewatering scenario is ongoing including a pump test that is planned for Q1 2017 to confirm dewatering rates prior to initiating a PEA in H2 2017.
