McEwen Mining Intersects 53.9 g/t Gold Over 8.3 m at the Froome Footwall

 

 

 

 

 

McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) reports an updated resource estimate for the Froome Deposit and highly encouraging exploration results from its ongoing $15 million exploration program at the Black Fox Complex near Timmins, Ontario, Canada.

 

 

Highlights include:

 

  • Froome Footwall: Drilling intersected 53.93 g/t gold over 8.29 m including 322.86 g/t gold over 1.34 m, along the footwall structure located approximately 150 m North of the main Froome deposit.
     
  • Froome Resource: Indicated resource estimate increased by 14% to 181,000 gold ounces at a grade of 5.09 g/t.
     
  • Pike River: Shallow high-grade intersection of 35.04 g/t gold over 3.30 m core length (CL) along the same 7 km long structural belt that hosts the Froome deposit and Gibson mineralization.
     
  • Grey Fox: Multiple shallow intersections including 13.41 g/t gold over 2.82 m including 27.70 g/t gold over 0.94 m, and 5.79 g/t gold over 1.99 m including 9.71 g/t gold over 0.93 m from a mineralized cross-structure located in the hanging wall of the 147 Zone, which has a current Indicated resource of 264,000 gold ounces at a grade of 7.49 g/t.
     
  • Black Fox Mine: 35.08 g/t gold over 1.69 m intersected on the depth extension of the mine. An underground exploration drift is under development and additional drilling will begin in mid-September.

 

 

Froome Footwall

 

 

Surface drilling at Froome during Q3 has been focused on two targets: 1) evaluating the down-plunge extension of the Froome Deposit, and 2) assessing the potential of the mineralized footwall, which returned 53.93 g/t gold over 8.29 m including 322.86 g/t gold over 1.34 m. The current interpretation suggests that this new occurrence extends the complex, braided ‘belt’ of elevated gold mineralization (running parallel to Froome) by approximately 350 m strike length to the East.

 

 

The addition of these new drill intersections within the Froome Footwall could provide an economic enhancement to the proposed underground development planned to commence later in September. Definition drilling to further evaluate the footwall target is ongoing.

 

 

Significant Froome Footwall drill intersections include:

TW = True width (mathematically calculated based on current interpretation)

 

 

Pike River Target

 

 

The Pike River Target Area, located between the Froome Deposit to the northwest and Gibson Deposit to the southwest, is underlain by the Gibson-Kelore Fault zone. These mineralized intercepts indicate the high potential for a new discovery within this underexplored segment of the Gibson-Kelore Fault Zone.

 

 

Significant Pike River drill intersections include:

 

 

Hole Area From (m) To (m) Length (m) TW (m) Gold (g/t)
18PR-032 Pike River 70.00 72.00 2.00 * 2.12
And   79.00 82.30 3.30 * 35.04
* True width unknown

 

 

Grey Fox – 147 Zone Hanging Wall Target

 

 

Previous exploration activities at Grey Fox focused on east dipping oreshoots. A 3,000 m drill program traced a mineralized cross-structure at a different orientation over a strike length of 140 m, and from the surface to a depth of 125 m. These results indicate that the mineralized cross-structure is continuous and traceable, and provides a framework for adding resource ounces at Grey Fox.

 

 

Significant Grey Fox drill intersections include:

 

 

Hole Area From (m) To (m) Length (m) TW (m) Gold (g/t)
18GF-1087 147 HW 30.10 33.48 3.38 2.76 1.14
And   129.90 136.00 6.10 4.96 3.64
Including   133.00 136.00 3.00 2.44 6.75

18GF-1092 147 HW 7.00 10.00 3.00 2.82 13.41
Including   9.00 10.00 1.00 0.94 27.70

 

 

Black Fox Underground

 

 

One underground drill rig has been testing the down-plunge extension of the Deep Central Zone (see Figure 1). Drilling intersected multi-phase quartz-carbonated veining, which returned an intercept of 35.08 g/t gold over 1.69 m including 55.10 g/t gold over 1.01 m. This represents the deepest high-grade intercept at the mine, and supports the belief that mineralization extends deeper down plunge. Drilling will resume in mid-September from better positions in the newly constructed drilling bays on the 810 m level.

 

 

Significant DCZ drilling highlights include:

 

 

Hole Area From (m) To (m) Length (m) TW (m) Gold (g/t)
520-EX346-42 DCZ 426.50 428.00 1.50 1.30 6.87
And   561.00 563.00 2.00 1.69 35.08
