Pistol Bay drills 5.15% zinc-equivalent over 12.85 metres at NW Ontario’s Confederation Lake

by Greg Klein | May 3, 2018

With three holes totalling 1,525 metres now complete out of a 3,500-metre winter-spring campaign, Pistol Bay Mining TSXV:PST released the first assay on May 2. The initial holes targeted the Arrow zone, part of the 100%-optioned, 15,000-hectare Confederation Lake project in northwestern Ontario.

Sunk on Arrow’s main sulphide zone, hole DDH GL18-02 gave up Russian doll interval-within-interval assays as follows:

Pistol Bay drills 5.15% zinc-equivalent over 12.85 metres at NW Ontario’s Confederation Lake

Pistol Bay hopes to upgrade last year’s
resource estimate for the project’s Arrow zone.

  • 3.07% zinc, 0.42% copper, 0.12% lead, 22.2 g/t silver and 0.59 g/t gold for 5.15% zinc-equivalent over 12.85 metres, starting at 422.95 metres in downhole depth
  • (including 3.82% zinc, 0.5% copper, 0.15% lead, 27.3 g/t silver and 0.71 g/t gold for 6.33% zinc-equivalent over 9.8 metres)
  • (which includes 4.83% zinc, 0.56% copper, 0.15% lead, 26.4 g/t silver and 0.45 g/t gold for 7.13% zinc-equivalent over 7.3 metres)
  • (which includes 8.88% zinc, 0.92% copper, 0.38% lead, 44.3 g/t silver and 0.38 g/t gold for 12.3% zinc-equivalent over 2 metres)
  • (which includes 22% zinc, 0.28% copper, 0.77% lead, 74.9 g/t silver and 0.77 g/t gold for 24.8% zinc-equivalent over 0.6 metres)

Overlapping some of these intervals was a three-metre section described as “conspicuous gold enrichment towards the top of the main sulphide zone”:

  • 0.83% zinc, 0.33% copper, 0.17% lead, 40.4 g/t silver and 1.65 g/t gold for 4.41% zinc-equivalent over 3 metres, starting at 426 metres

A 43-101 resource released last year for Arrow used a base case 3% zinc-equivalent cutoff for an inferred category showing:

  • 2.1 million tonnes averaging 5.78% zinc, 0.72% copper,19.5 g/t silver and 0.6 g/t gold, for a zinc-equivalent grade of 8.42%

Contained amounts come to:

  • 274 million pounds zinc, 34.3 million pounds copper, 1.33 million ounces silver and 41,000 ounces gold

But recent drilling suggests Arrow might consist of “two separate zones arranged en echelon or that the southwestern part is displaced from the northeastern part by a fault,” Pistol Bay stated.

Still to come are assays for the two remaining holes.

From Arrow, the rig moves about eight kilometres west to sink three more holes on the property’s Fredart A zone, also known as Copperlode A. Work dating to the 1960s resulted in two conflicting historic, non-43-101 estimates of 386,000 tonnes averaging 1.56% copper and 33.6 g/t silver, or 219,500 tonnes averaging 1.95% copper and 41.8 g/t silver.

The drill program follows last year’s VTEM-Plus survey, the area’s first exposure to state-of-the-art regional geophysics.
