(Includes 374% increase in Inferred Mineral Resources)

Shares Issued: 200,406,337

THUNDER BAY, ON , March 21, 2017 /CNW/ - PREMIER GOLD MINES LIMITED ("Premier" or "The Company") (PG.TO) is pleased to release an updated Mineral Resource estimate for the Company's 100%-owned McCoy-Cove Property, located 32 miles south of Battle Mountain in Lander County, Nevada . The estimate, completed by RPA Inc. of Toronto, Ontario (with an effective date of March 21, 2017 ) is the culmination of a very successful multi-year exploration and delineation drilling campaign by Premier that focussed on the Helen, CSD Gap and 2201 Zone target areas.

Table 1 provides a summary of the Mineral Resources at McCoy-Cove. Highlights of the estimate include:

  • Total Indicated Mineral Resources of 614,000 tonnes grading 11.57 g/t Au (228,000 ounces of gold), an increase of 59% versus the 2013 resource estimate.
  • Total Inferred Mineral Resources of 3,378,000 tonnes grading 12.17 g/t Au (1,322,000 ounces of gold), an increase of 374% versus the 2013 resource estimate.
  • An increase in the grade of both Indicated and Inferred mineral resources of 11% and 24% respectively.
  • Preliminary Economic Assessment (PEA) underway as part of a US$13.4M program in 2017.
  • Exceptional exploration potential remains a hallmark of this property.

"With this updated resource, McCoy-Cove now ranks amongst the most significant exploration successes in recent memory in Nevada ," commented President & CEO Ewan Downie on the Company's C-Suite Blog (http://www.premiergoldmines.com/news/c-suite-blog). "This is the result of excellent work by our on-site and technical team and confirms the potential of this emerging high-grade development opportunity."

Importantly, the mineral resources have been estimated following creation of a robust litho-structural model that unifies the stratigraphic, structural, intrusive and alteration elements that are common with other world-class Carlin-style deposits in Nevada . Further refinements to the model are being conducted on an ongoing basis.

Figure 1 is a longitudinal section profiling the location and geological context of each of the reported resource areas. Premier will continue to seek increasing property-wide resources by testing several existing and new exploration targets that have been refined as a result of a successful 2016 campaign.

Notes:




1.

CIM definitions were followed for mineral resources

2.

Mineral Resources are estimated at a cut-off grade of 5.6 g/t Au

3.

Mineral Resources are estimated using a long-term gold price of US$1400 per ounce

4.

A minimum mining width (vertical height or lens thickness) of 8 feet has been used

5.

Bulk density is 2.1 t/m3 for CSD, GAP and Helen, and 2.6 t/m3 for 2201 & VG.

6.

Numbers may not add due to rounding.

 

The Mineral Resource estimate used the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Definition Standards for Mineral Resources and Mineral Reserves, Definitions and Guidelines prepared by CIM Standing Committee on Reserve Definitions and adopted by CIM Council on May 10 , 2014. The mineral resource estimate is classified as "indicated", or "inferred" as defined by CIM. Premier is not aware of any environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issue that could materially affect the Mineral Resource estimate.

The key assumptions and parameters used in the estimate of the Mineral Resources are summarized as follows:

  • A one pass, ID4 interpolation method was used in this mineral resource estimate
  • High grade assays were manage utilizing a 60 g/t Au capping grade on raw assays for all lenses
  • The compositing was realized on full intercept length
  • Indicated classification has been applied to blocks interpolated using at least 3 drill holes
  • Inferred classification has been applied to remaining blocks within the ore wireframes
  • Ore shapes were trimmed to contain only above cut-off grade composites, and expanded approximately 100 ft past last known pierce point


A comprehensive description of key assumptions and parameters used will be set out in a technical report that will be available on SEDAR and Premier's website within 45 days of this press release.

McCoy-Cove PEA Study Confirmed

As a result of the high-grade nature of, and significant increase in the McCoy-Cove mineral resource estimate, Premier today confirms that it is now undertaking a Preliminary Economic Assessment (PEA) at McCoy-Cove and is targeting its completion during H2 of 2017. The PEA is being conducted by Practical Mining LLC of Elko, Nevada , utilizing the support of Premier's Nevada -based operating team working under the direction of Brent Kristof , Premier's Senior Vice President of Operations. Upon completion of the PEA, Premier anticipates collaring the authourized underground exploration decline in Q4 2017 to allow for an advanced underground drilling and test mining program in 2018. With a successful program, this work will augment completion of a Feasibility Study thereafter.

2017 Infill & Exploration Program

The 2017 program will consist of 17,000 metres and US$5.0M in expenditures will focus on select infill drilling of the Helen and Gap deposits as well as testing multiple priority exploration targets across the property. Highlight results include:

Infill

  • Infill drilling of the Helen Zone has confirmed mineralization in PG17-04: 9.07 g/t Au and 2.89 g/t Ag over 1.7m at 598.0m and 9.31 g/t Au and 12.11 g/t Ag over 5.5m at 642.2m.
  • PG17-07: 9.06 g/t Au and 4.65 g/t Ag over 2.8m at 434.0m and 8.23 g/t Au and 2.55 g/t Ag over 11.4m at 596.0m and 29.52 g/t Au and 8.48 g/t Ag over 5.9m at 629.3m.


Exploration

  • Drilling at the Windy Point target has identified a large mineralized system in PG17-13: 0.66 g/t Au and 0.10 g/t Ag over 197.2m at 402.3m including 7.11 g/t Au and no detectable Ag over 1.8m at 459.0m and 1.03 g/t Au and 0.07 g/t Ag over 58.4m at 541.2m.


Drilling is ongoing and assays are pending on multiple drill holes with a full exploration update planned for early Q2 2017.
