Premier confirms mineral resources at Hasaga

Shares Issued: 201,313,187

THUNDER BAY, ON, Jan. 11, 2017 /CNW/ - PREMIER GOLD MINES LIMITED ("Premier" or "The Company") (TSX:PG) is pleased to confirm a maiden Mineral Resource estimate for the Company's 100%-owned Hasaga Property, located in Red Lake, Ontario, Canada some 440 kilometres northwest of Thunder Bay. The estimate, completed by MRB and Associates of Val-d'Or, Quebec (with an effective date of December 30th, 2016) has been completed following a two-year exploration and delineation drilling campaign by Premier that focussed on the Central, Hasaga and Buffalo target areas.

Table 1 provides a property-wide summary of the Mineral Resources at Hasaga, while Table 2 separates the Mineral Resources into respective target areas described in earlier press releases.

Highlights of the December 30th, 2016 Hasaga estimate include:

  • Total Indicated Mineral Resources of 1,123,900 ounces of gold
  • Total Inferred Mineral Resources of 630,500 ounces of gold
  • Central Zone Indicated Mineral Resources of 803,900 ounces of gold and 583,000 ounces inferred
  • Resources restricted to having open-pit potential only; underground potential untested
  • Mineral resources constrained by property boundary and within an optimized pit shell

"Our focus on resource delineation at Hasaga has resulted in a discovery cost of less than $17.00 per indicated resource ounce" commented Premier Executive Vice-President Stephen McGibbon 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 team and an important first step toward assessing the future mining potential at Hasaga."

Importantly, the estimated resources are hosted within mineralization that remains open at depth. Premier will seek to increase property-wide resources by testing for potential higher grade mineralization in 2017 that may be amenable to underground mining methods.

  • Independent Qualified Persons for the Hasaga Mineral Resources Estimate are Abderazzak Ladidi P.Geo and Vincent Jourdain, Eng., Ph.D from MRB & Associates and the effective date of the estimate is December 30th 2016
  • CIM definitions were followed for Mineral Resources
  • Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
  • The estimate includes 13 mineralized zones (3 in Buffalo sector, 6 in Hasaga sector, 4 in Central sector) and 2 lithological envelopes
  • High gold assays were capped at 15 g/t
  • Bulk density data were averaged on a per zone basis (1220, 1230, 1320:2.71 t/m3; 1330, 1510, 1540, 2399: 2.72 t/m3; 1520, 1525: 2.74 t/m3; 1210, 1340: 2.75 t/m3; 1515, 2599: 2.77 t/m3; 1530: 2.79 t/m3; 1310: 2.83 t/m3)
  • Resources were evaluated from drill hole and channel samples using a 5-pass ID2 interpolation in a block model (block size = 5 x 5 x 5metres)
  • Open pit resources are constrained to the property limit in an optimized pitshells at a cut-off grade of 0.5 g/t Au
  • Pitshell optimization parameters: Mining cost = CAD$2.50/t, milling cost = CAD$12.00/t, G&A = CAD$3.00/t, Gold price US$1400/oz (exchange rate CAD$1.30 = US$1.00), milling recovery = 94%, mining recovery = 100%, mining dilution = 0.0%, pit slope = 55°
  • Totals may not add correctly 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 "measured", "indicated", or "inferred" as defined by CIM.

  • Totals may not add correctly due to rounding

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

  • The 5-pass ID2 interpolation method was used in this mineral resource estimate.
  • The optimized pit shell used reflects a revenue factor of 0.74.
  • High grade (outlier) assays managed utilizing a 15 g/t Au capping grade on raw assays as well as using a restricted search approach with a grade threshold established on composites on a per zone basis (generally 3-6 g/t Au) within half of the variography derived search range.
  • An exchange rate of CAD $1.30 to US$1.00 has been assumed.
  • Mineral resources have been restricted to no closer than 50 metres of any shoreline, but are not restricted by cultural effects such as roads and buildings.
  • Total number of below cut-off (waste) tonnes contained within the optimized pits is some 94,000,000 tonnes.

Hasaga Metallurgy Summary

In December, Premier reported on a recently completed metallurgical scoping program on samples from the Hasaga, Central and Buffalo Zones with the intent to characterize the lithological and mineralization domains of the project areas, and to complement the Hasaga mineral resource estimate. Although bottle roll tests utilizing coarser crush sample composites (¼", ½", ¾" crush sizes) does not support a potential heap leach recovery process, the baseline bottle roll cyanidation study indicated very good recoveries for all grade ranges with metallurgical results of between 94% and 97% when grinding to 80% passing 200 mesh.

Investor Day

Premier will be hosting an Investor Day presentation at the Toronto Board of Trade (4th floor, rooms A/B), 1 First Canadian Place, Toronto, Ontario at 10:00am (EST) on Thursday, January 12, 2017.  The Company invites all current and future shareholders to attend this event.
