McEwen Mining: Exploration at Fox

 

 

 

 

 

Building a stronger foundation

 

 

McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to announce that drilling continues to deliver good widths and grades at the Fox Complex, both from exploration at Stock and delineation at Froome.

 

Highlights include:

  • Assay results show the potential of the Stock mineralized zones to extend to depth and down plunge. What has been outlined to date will contribute to our immediate growth plans.
  • Drilling is planned for 2022 to investigate the intercept in hole S21-202, which encountered 21 meters of 4.29 g/t gold. If this intercept connects to mineralization at Stock West, it will materially enlarge the boundaries of the Stock West system.
  • Assay results are starting to arrive from our exploration on Stock Main (the historic Stock mine). Visible gold has been noted in several drill cores, such as in hole SM21-024 that returned 9.1 m of 7.43 g/t gold including 2.6 m of 23.72 g/t gold, within 25 m of surface.

 

Stock West & Main

 

Drill results from holes S21-202 (released on Nov. 3, 2021) and S19-95 (released on Sep. 4, 2019 – 7.0 m (core length) of 27.2 g/t gold) confirm that mineralization remains open to depth and the east (see Figure 1). The intercept in S21-202 is an over 200 m step-out along a prominent shallow eastern plunge from mineralization at Stock West. The current geologic interpretation suggests a possible connection of a further 250 m to the intercept in hole S19-95.

 

The host lithology of the Stock West mineralization, which also occurs in hole S21-202, was recently intersected in the footwall of the Stock mine. These observations support our confidence that the property is early in its discovery phase of development.

 

Forty-six surface drill holes were completed at Stock West (see Table 1) and Stock Main (see Table 2) since the last exploration update in May 2021.

 

Progress made at the Stock Property in 2021 will be reflected in the pending Preliminary Economic Assessment for the Fox Complex, which is currently being finalized for publication.

Froome Mine

 

The best new result is 20 m (true width) of 7.43 g/t gold – Hole 200-F085-14

 

Three hundred and seventeen underground drill holes were completed for delineating the Froome orebody during 2021 (see Table 3). The Froome mine, while only a short distance from the Black Fox mine, is different in important ways that offer several advantages, such as a straighter, shorter, and more efficient underground haulage route, and wider more consistent mineralization that is amenable to lower-cost bulk mining methods. Mining started earlier this year and has been meeting expectations on key ore quality indicators such as gold grade, dilution, and total ounces produced.

Delineation drilling has expanded the deposit further to the west than previously designed, giving the Fox Complex team confidence that the Froome mine life will be extended. 2022 diamond drilling will focus on resource expansion at depth to extend the Froome mine life (see Figure 2).
