Includes 25.9 m of 13.33 g/t Au and 18.3 m of 26.76 g/t Au

Premier Gold Mines Limited (TSX: PG) (OTCPK: PIRGF) is pleased to announce additional results from the 2020 drill program focused on expanding mineralization at the El Nino underground mine on the Company’s 40%-owned South Arturo Property. Located on the prolific Carlin Trend of Nevada, the South Arturo Mine is a joint venture between Premier and Nevada Gold Mines LLC, a joint venture between Newmont Mining Corporation and Barrick Gold Corporation operated by Barrick.

 

Highlight intercepts from the drill program include:

 

  • 25.9 m of 13.33 g/t Au includes 18.3 m of 15.84 g/t Au (SEC20004)
  • 10.7 m of 10.70 g/t Au and 16.8 m of 8.57 g/t Au and 18.3 m of 6.77 g/t Au (SEC20008)
  • 9.1 m of 24.11 g/t Au and 6.1 m of 7.84 g/t Au and 3.1 m of 20.45 g/t Au (SEC20009)
  • 3.1 m of 29.21 g/t Au and 18.3 m of 26.76 g/t Au and 4.6 m of 7.05 g/t Au (SEC20010)
  • 3.1 m of 55.73 g/t Au and 3.1 m of 7.08 g/t Au (SEC20011)
  • 6.1 m of 10.46 g/t Au and 10.0 m of 9.45 g/t Au (SER20022)

 

Highlight intercepts from previously released drill holes in 2020 include:

 

  • 41.1 m of 7.37 g/t Au (SEC20003)
  • 100.6 m of 5.72 g/t Au (SER20018)
  • 39.6 m of 17.11 g/t Au (SER20019)
  • 45.7 m of 6.79 g/t Au includes 9.1 m of 10.15 g/t Au and 4.6 m of 18.82 g/t Au (SER20025)

 

“The highly successful drill campaign in 2020 at El Nino has returned numerous impressive intercepts with excellent grade and width that bode well for the future of the mine”, stated Ewan Downie, President and CEO of Premier. “Multiple holes from the program intersected multiple zones of mineralization and we expect an increase reserves and resources and an expanded mine life. The deposit remains open at depth and along strike”.

 

El Nino is a Carlin-type deposit hosted in a silica-sulphide breccia within the Rodeo Creek formation near the contact with the Bootstrap limestone. Ore from El Nino is processed at Nevada Gold Mines’ nearby Goldstrike facility.  Exploration drilling in 2020 tested the down-plunge extent of mineralization at intersections of favorable structures, where high-grade ore often resides.

 

Results received to date (see Figure 1 and Table 1) indicate that the 2020 delineation campaign has successfully extended high–grade mineralization more than 100 m below existing mine workings and confirms the likelihood to continue expanding high-grade mineralization at depth. The irregularly shaped mineralization mapped from mining excavations suggest true widths are 40% to 80% of the core lengths summarized in Table 1. Assays results from six drill holes completed in the northern portion of the lower El Nino target are pending. In 2021, 6,000 metres of drilling is planned to further define and expand the ore body that remains open at depth to the east and along strike north and south.

In addition to the drilling completed in 2020 at El Nino, a surface drilling program was also completed proximal to the Phase 1 pit and Phase 3 deposit in an effort to better define near-surface mineralization potentially amenable to heap leach processing and to test potential high-grade targets. Results from this program are expected to be received in the first quarter. Part of the ongoing work being performed at South Arturo include trade-off work associated with the Phase 3 project (open pit vs underground) and progressing a revised mineral resource estimate that will then be completed once all assay results from 2020 are received.
