Ann: NW Flank yields multiple outstanding gold intersections, page-21

Well aliens, that would be an option but consider the trucking time. In the time it takes to truck a load to and from Challenger, about 10 truck loads could be delivered to a nearby heap leach stack.

This was in the MEU 30 Jan 20 report:

"Column Leach tests yield excellent Gold Recoveries
! During the quarter, the first column leach testwork, carried out by Bureau
Veritas, returned excellent gold recoveries of 83% … which is considered very
high by industry standards for column leach metallurgy [ ASX:MEU 10 Oct 2019 ]
! Suggests Aurora Tank is likely to be amenable to low-cost low-capex heap leach
techniques
! A heap leach means Marmota would not need to construct a mill, nor share
revenue with external parties for toll treatment in a mill."
