Shares Issued:  170,692,322

THUNDER BAY, ON, July 23, 2015 /CNW/ - PREMIER GOLD MINES LIMITED ("Premier" or "The Company") (TSX:PG) is pleased to confirm a current Mineral Reserve and Resource estimate for the Company's 40%-owned South Arturo Mine, located in Elko County, Nevada some five (5) kilometres northwest of the Goldstrike operations of Barrick Gold Inc. The South Arturo Mine is a joint venture between Barrick's wholly-owned subsidiary Barrick Gold Exploration Inc. (60%) and Premier. The estimate, completed by Barrick Gold (with an effective date of December 31, 2014) is documented in an independent technical report completed on behalf of Premier by Roscoe Postle Associates Inc. (RPA).

Table 1 provides a deposit summary of the Mineral Resources at South Arturo, while Table 2 provides a deposit summary of Mineral Reserves.

Highlights of the December 31, 2014 South Arturo estimates include:

  • Measured & Indicated Resources exceed 830,000 ounces gold and 4.3 million ounces of silver on a 40% basis.
  • Probable Reserves exceed 160,000 ounces gold on a 40% basis
  • Probable Reserve grade exceeds 4.00 grams per tonne gold

"Barrick's work at South Arturo has been conducted with a high degree of professionalism" commented Premier President & CEO Ewan Downie. "With mine construction well underway, Premier is now participating in the joint venture as a fully-engaged partner."

  1. CIM definitions were followed for Mineral Resources.
  2. Mineral Resources are estimated using a long-term gold price of US$1,400 per ounce, a long term silver price of US$19, and a C$/US$ exchange rate of 1.10.
  3. Mineral Resources are reported using cut-off grades of 0.79 g/t Au, 1.20 g/t Au, and 1.89 g/t Au for the oxide mill, refractory roaster and total carbonaceous material (TCM), respectively, and a grade range from 0.14 g/t Au to 0.79 g/t Au for heap leach material.
  4. Mineral Resources represent attributable ounces to Premier, equal to 40% of the Joint Venture controlled ounces. Material from the Rossi property has been excluded.
  5. Bulk density is specific to geological formation and varies from 2.00 t/m3 to 2.67 t/m3.
  6. Mineral Resources are exclusive of Mineral Reserves.
  7. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title socio-political, marketing or other relevant issues. In addition, The quantity and grade of reported inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred Mineral Resources as an indicated or measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured Mineral Resource category.
  8. Numbers may not add due to rounding.
