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 step-out drilling within the 400m Gap (CSD Gap) between the Helen Zone and historic Cove South Deep (CSD) underground deposit continues to confirm the extension of high-grade mineralization across substantial widths at the Company’s 100%-owned McCoy-Cove Gold Project, located along the Battle Mountain-Eureka Trend in Nevada.

The focus of the ongoing 15,000 metre, 23-hole drill program is to test for continuity and expansion of the Carlin-style gold and silver system within the CSD Gap, as shown in Figures 1 and 2 below. Results from drill-hole PG16-06, a 100m step-out both up-dip and along strike from hole PG16-02 has extended mineralization towards the Helen Zone with similar grades and thickness. Hole PG16-06, like PG16-02 (previously announced), is one of the higher grade intercepts drilled on the property to-date and indicates the CSD Gap horizon remains open for further expansion. Premier is planning to update all mineral resources on the project by Q1 2017 after the conclusion of the current drill program.


Highlights of the recent results include:

  • PG16-05: 4.57 g/t Au and 1825.00 g/t Ag over 1.0m (0.14 oz.t Au and 53.23 oz./t Ag over 3.4ft.) at 626.7m
  • PG16-06: 7.96 g/t Au and 4.68 g/t Ag over 38.0m (0.23 oz.t Au and 0.14 oz./t Ag over 124.8 ft.) at 645.1m including 17.03 g/t Au and 8.82 g/t Ag over 14.2 m (0.50 oz./t Au and 0.26 oz./t Ag over 46.7 ft.)

“The impressive thickness and high-grade results demonstrated by initial infill drilling of the CSD Gap horizon highlight the potential to significantly add to the resources at McCoy-Cove” stated Chad Peters, Nevada Exploration Manager for Premier on the Company’s C-Suite Blog (

A re-interpretation of the geological model indicates that the most robust gold and silver mineralization 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 drill results from PG16-01 through PG16-06 support the thrust-hosted model that envisions greater continuity of the wide mineralization between zones. The ongoing drill program will further test this thesis and positive results will ultimately increase to the 2013 mineral resource estimate. Also of interest, other northwest striking thrust faults have been identified on the property, including the McCoy thrust which acted as a similar control for the mineralization of the McCoy deposit located some 1.2 kilometres to the southwest. Exploration will continue to focus on evaluating known and previously untested thrust fault targets across the property.

Given the upside of the project, 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 heap leach pads; assay results are expected in the near future.

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 as well as underground exploration access to the Helen deposit. 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 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.
