Premier Extends High Grade Mineralization at Mccoy-Cove

Download Press Release


PREMIER GOLD MINES LIMITED (TSX:PG) (“Premier”, “the Company”) is pleased to announce that drilling has confirmed the extension of high-grade mineralization between the Helen Zone and the historic Cove South Deep (CSD) underground deposit at the Company’s 100%-owned McCoy-Cove Gold Project, located along the Battle Mountain-Eureka Trend in Nevada.

The focus of the ongoing 10,000 metre, 15-hole drill program is to test for continuity and expansion of the high grade gold and silver system within the 400-metre gap between the two zones, as shown in Figures 1 and 2 below. Results from the first two holes (PG16-01 and PG16-02) confirms a 100m step-out on mineralization both down dip and along strike from hole PG-01, a 2014 exploration hole that intersected the “Carlin-style” mineralization beneath the Cove Pit. Hole PG16-02 is one of the best intercepts drilled on the property to-date and both holes returned thick intercepts of continuous lower grade mineralization. Most importantly, the mineralization remains open for expansion within the gap and drilling continues. Following completion of the drill program Premier anticipates calculating a mineral resource estimate for the Helen and CSD deposits.


Highlights of the recent results include:

  • PG16-01:8.73 g/t Au and 11.82 g/t Ag over 6.3m (0.25 oz.t Au and 0.34 oz./t Ag over 20.6 ft.) beginning at 601.0m
  • PG16-02: 7.08 g/t Au and 19.19 g/t Ag over 50.9m (0.21 oz.t Au and 0.56 oz./t Ag over 167 ft.) beginning at 598.0m

“The continued success of the drill program demonstrates the potential to delineate significant high grade gold and silver mineralization at McCoy-Cove” stated Stephen McGibbon, Executive Vice-President for Premier. “Management continues to view the McCoy-Cove Property as a cornerstone asset within the Company’s portfolio and is aggressively pursuing several scenarios to develop operations on the project.” 

A recent re-interpretation of the Cove geological model proposes that the best gold and silver grades in the Helen, CSD and 2201 Zone deposits are closely associated with the deep seated Cove thrust fault which acted as both primary structural control and fluid conduit for all known Cove deposits (Figure 2). Initial re-modelling efforts for the Helen and CSD zones support the thrust-hosted model and select infill drilling will further test the model and confirm whether greater continuity of mineralization, than was reflected in the 2013 Helen Zone resource estimate, exists. Additional northwest striking thrust faults have also been identified on the property, including the McCoy thrust which acted as a similar control for the mineralization of the McCoy deposit located 1.2 kilometres to the southwest. Future exploration will focus on testing known and previously untested thrust fault targets across the property.

To support mine development scenarios, Premier is also completing baseline environmental and metallurgical work on the Helen and CSD deposits. This work includes investigating the potential to reprocess the historic heap leach pad material.A sonic drill program was completed in May 2016 on three of the heap leach pads with results expected toward the end of Q2. The material and grades appear to justify advanced metallurgical work, including bottle roll and column leach tests, with initial results expected toward the end of Q3. Of interest, a similar reprocessing program has been successfully implemented by Newmont at its nearby Lone Tree operation.

The McCoy-Cove Property is located along the prolific Battle Mountain-Eureka Trend that is host to numerous multi-million ounce producing and past-producing mines.The property is located in close proximity to excellent infrastructure (including paved roads & power).All permits are in place for an expanded surface drilling campaign and include access to underground. The McCoy-Cove gold mines produced 3.3 million ounces of gold and 110 million ounces of silver between 1986 and 2003, a 17-year period of relatively low to historically low gold and silver prices.The mines are believed to have a close genetic relationship and association with the same feeder-fault structures; however the ores mined did occur in different rock units. The feeder structures between the mines have been subjected to only limited exploration in the past and represent a priority target for future exploration.
