ElP,
With all them 8 drills on the ice I think Dave is going for a slam dunk. As one poster said Dave knows "what lies beneath"... with or without the Walmart metal (Au) detector.
The supply line must be quite busy with skidoos running up and down, day and night, along that stretch of ice, keeping drill crews warm with hot chocolate and high energy munchies. It must be a pretty sight with 8 drills @ 100m apart against the white snow on the lake.
With this scale of operation, it wouldn't be too far-fetched to talk about a 1000m extension of the HGZ and 10-12 Moz Au at Borden Gold (Note: PRB already has a pit-constrained resource of over 4 Moz Au).
I would stick with my number, north of $10/s. The only question is how far north?
