Premier Expands High-Grade Mineralization at El Nino, Nevada

 

 

 

 

 

 

Premier Gold Mines Limited (TSX: PG) (OTCPK: PIRGF) is pleased to announce positive drill results from expansion drilling at the El Nino underground mine on the Company’s 40%-owned South Arturo Property, located in the Carlin Trend of Nevada. The South Arturo Mine is a joint venture between Premier and Nevada Gold Mines LLC. These step-out drill results are part of a campaign of 25 holes (3,500 m) designed to substantially increase the extent of known mineralization at depth.

 

Highlight intercepts from the ongoing drill program include:

 

  • 39.6 m of 17.11 g/t Au includes 21.3 m of 24.75 g/t Au (SER20019)
  • 100.6 m of 5.73 g/t Au includes 13.7 m of 8.52 g/t Au (SER20018)
  • 41.1 m of 7.37 g/t Au includes 13.7 m of 11.83 g/t Au (SEC20003)
  • 32.0 m of 7.65 g/t Au includes 10.7 m of 14.83 g/t Au (SER20017)

 

Additional results from the 2020 drilling campaign are pending.

 

“El Nino has returned excellent grade and width intercepts in 2020 that bode well for the future of the mine”, stated Peter Van Alphen, Chief Operating Officer of Premier. “We are hopeful to see an increase in year-end reserves and resources based on these successes that will provide for an expanded mine life. The deposit remains open at depth and along strike”.

 

The El Nino Mine is located on the northern end of the prolific Carlin Trend. As at June 30, 2020, production at El Nino for the year had exceeded 550 tonnes per day at 8.90 g/t Au (100% basis) resulting in 11,495 ounces of production attributable to Premier and supporting all-in sustaining costs (AISC) of $1,031 per ounce sold. Since declaring commercial production in October 2019, the mine has maintained strong performance.

 

El Nino is a Carlin-type deposit hosted in a silica-sulphide breccia within the Rodeo Creek formation at the contact with the Bootstrap limestone. Exploration drilling in 2020 is testing the down-plunge extent of mineralization at intersections of favorable structures, where high-grade ore often resides. To-date, the results of this campaign (see Table 1 and Figure 1) indicate the ore body remains open to the east and along strike north and south.

 

The 2020 program at El Nino includes both in-fill and step-out drilling from underground drill stations proximal to existing mine areas and at depth. The irregularly shaped mineralization mapped from mining excavations suggests true widths are likely 60% to 80% of the lengths summarized in Table 1. The intercept summarized for hole SER20025 may be tracing sub-parallel to its host structure.

 

Additional drilling is currently underway at targets proximal to the proposed Phase 1 and Phase 3 pit projects and results are expected to be received in the fourth quarter. Following the 2020 campaign, a revised mineral resource estimate will be completed.
